内由於液態工作介質回流不及時，造成蒸發腔225内供液 不足而發生乾涸或燒毁。同時，蒸發腔225内液態工作介 質吸熱蒸發膨脹成氣態後，由於毛細結構20的第二支撐 壁222的阻擋，蒸氣不會倒流至儲液室220内產生漏熱（ 即蒸發腔225内的熱量進入儲液室220内造成蒸發部11性 能下降甚至失效），而只能順沿蒸氣槽227流向蒸氣室 228並通過與蒸氣室228連通的蒸發部出口 116進入蒸氣 管線13内，如此更有利於提升迴路熱管10的性能。另外 ，由於該毛細結構20支撐於該蒸發部11的蓋板113與底板 110之間，該毛細結構20自身具有較強的支撐強度，從而 可以加強蒸發部11的抗壓強度，因此，該蒸發部11的底 座111及蓋板113均可以採用更薄的殼體制成，從而減小 099128164 表單編號A0101 第10頁/共22頁 0992049521-0 201209366 Ο Ο

The evaporating part is affixed with a capillary structure, and the inner surface is provided with a working medium for storing the temporary cavity. When the heat pipe of the circuit is purchased, the evaporation portion of the object is heated. The liquid working medium of the wool structure absorbs the sucking ❹, and the working state of the gaseous state temporarily fills the air-testing part, and the heat is condensed and contracted into the cold part, and the cold__ quality is returned to the evaporation part via the liquid pipeline.

SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a loop heat pipe that can effectively improve work performance. [0006] A loop heat pipe includes an evaporation portion, a condensation portion, a vapor line, and a liquid line. The vapor line and the liquid line are disposed between the evaporation portion and the condensation portion, and the evaporation portion and the condensation portion are connected in a loop. Filled with a working medium, the evaporating portion is provided with a capillary structure including a flat plate portion attached to the bottom surface of the evaporation portion, a support wall extending from the flat plate portion to the top surface of the evaporation portion, and a side from the side of the support wall to the vapor line a plurality of strip portions extending on one side, the support wall and the strip portion partitioning a space in the evaporation portion into a liquid storage chamber communicating with the liquid line and a vapor chamber communicating with the vapor line, adjacent two shapes A vapor tank that communicates with the vapor chamber is formed between the portions. [0007] Compared with the prior art, the evaporation portion of the loop heat pipe is divided into a liquid storage chamber and an evaporation chamber by a capillary structure. During operation, the liquid storage medium can store more liquid working medium and accumulate in the storage. The liquid working medium of the liquid chamber can be replenished to the inside of the capillary structure in time, thereby avoiding the backflow of the liquid working medium in the evaporation chamber, which causes the liquid in the evaporation chamber to be insufficiently dried or burned; and the gaseous working medium in the evaporation chamber Blocked by the support wall, it will not flow back to the reservoir to generate heat leakage, which is beneficial to improve the performance of the loop heat pipe. [Embodiment] Referring to Figure 1, a loop heat pipe 10 in a first embodiment of the present invention includes an evaporation portion 11, a condensation portion 12, a vapor line 13, and a liquid line 14 099128164.

The side plates 2 located at the left and right ends of the evaporation portion 11 are respectively provided with an evaporation portion inlet 115 connected to one end of the liquid line 14 and an evaporation portion outlet 116 connected to one end of the vapor line 13. ο The capillary structure 20 is a metal powder sintered capillary structure having a large number of pores therein so as to adsorb a large amount of liquid working medium in the pores. The capillary structure 20 includes a rectangular flat plate portion 21, an annular receiving portion 2 2 extending upward from an upper surface of one end of the flat plate portion 21, and a side from the side of the receiving portion 22 to the flat plate portion 21. The other end has a plurality of strip portions 23 extending horizontally. The shape and size of the flat plate portion 21 are opposite to the shape and size of the bottom plate 110 of the evaporation portion 11, and when the thin structure 2 is accommodated in the evaporation portion 11, the flat plate portion 21 can be attached to the evaporation portion. ^ on the upper surface of the bottom plate 110. [0011] Referring to FIG. 3, the accommodating portion 22 includes a first supporting wall 221 and a second supporting wall 222 which are parallel to each other and are respectively connected to the two ends of the first supporting wall 221 and the second supporting wall 222. A third support wall 223 and a fourth support wall 224 are parallel to each other. The first support wall 221 is flush with the edge of the left end of the flat portion 21. The center of the first support wall 221 is provided with a square notch 226. The second support wall 222 is spaced apart from the first support wall 221 099128164 Form No. A0101, page 7 / 22 pages 0992049521-0 201209366, and the second support wall 222 divides the space in the evaporation portion 11 into the liquid storage chamber 220 And two parts of the evaporation chamber 225. The first, second, third, and fourth support walls 221, 222, 223, and 224 are collectively formed to define the liquid storage chamber 220. The interval between the second support wall 222 and the first support wall 221 is less than one-half of the length of the flat plate portion 21 such that the length of the liquid storage chamber 220 is less than one-half of the length of the flat plate portion 21. In the present embodiment, the length of the liquid storage chamber 220 is approximately one fifth of the length of the flat plate portion 21. The thickness of the second supporting wall 222 is greater than the thickness of the first supporting wall 221, and the liquid working medium in the liquid storage chamber 220 penetrates into the strip portion 23 by the capillary force of the second supporting wall 222, and the second support The wall 222 can block the return of the gaseous working medium within the evaporation chamber 225 into the reservoir 220. The third and fourth support walls 2, 23, 224 are flush with the edges of the front and rear sides of the flat plate portion 21, respectively. The heights of the first, second, third, and fourth support walls 221, 222, 223, and 224 are substantially equal to the heights of the side plates 112 of the evaporation portion 11, and when the capillary structure 20 is received in the evaporation portion 11, The lower surface of the cover plate 113 is in contact with the top ends of the first, second, third, and fourth support walls 221, 222, 223, and 224, and the first support wall 221 and the evaporation portion 11 are provided with the evaporation portion inlet 115. The side panels 112 on one side are attached to each other, and the notches 226 are horizontally aligned with the evaporation portion inlets 115. [0012] Please refer to FIG. 4 to FIG. 5 at the same time, the strip portion 23 is located in the evaporation chamber 225. Each of the strip portions 23 has a rectangular shape and extends perpendicularly from the second support wall 222 in a direction away from the liquid storage chamber 220. The strip portions 23 are parallel to each other and spaced apart from each other, wherein the outermost two-shaped portions 23 are spaced apart from the edges on the front and rear sides of the flat plate portion 21. The sum of the length of the strip portion 23 and the length of the liquid storage chamber 220 is smaller than the length of the flat plate portion 21, and therefore, each strip portion 099128164 Form No. A0101 Page 8 / Total 22 Page 0992049521-0 201209366 Ο [0013] The end of the crucible 23 away from the second support wall 222 is spaced apart from the right end edge of the flat plate portion 21. The height of the strip portion 23 is substantially equal to the degree of the side plate 112 of the evaporation portion ' 'When the capillary structure 20 is received in the evaporation portion η', the top end of each strip portion 23 and the lower surface of the cover plate 113 A vapor chamber 228 is formed between the end of the strip portion 23 and the side plate 11 2 on the side of the evaporation portion 11 where the evaporation portion outlet 1 丨 6 is disposed; between any two adjacent portions 23 And a rectangular vapor groove 227 that communicates with the vapor chamber 228 is formed between the outermost two-shaped portion 23 and the side plates 112 on the front and rear sides of the evaporation portion u. The vapor chamber 228 and the liquid storage chamber 22 are located at opposite ends of the evaporation portion 11, respectively. The condensing portion 12, the vapor line 13 and the liquid line 14 are respectively in a circular tube shape, and the condensing portion 12 is parallel to each other.

The liquid is shrunk into a liquid state, and then flows from the condensing portion outlet 123 to the evaporation portion 11 via the liquid line 14. Finally, the condensed working medium is returned from the evaporation portion inlet 115 to the liquid storage chamber 220 of the evaporation portion 11, and the liquid storage chamber 220 is inside. The working medium is further replenished into the strip portion 23 of the capillary structure 20 of the evaporation portion 11 to enter the next cycle. [0015] Since the evaporation portion 11 is provided with the liquid storage chamber 220 and the evaporation chamber 225 which are isolated from each other. The liquid heat pipe 10 can store a large amount of liquid working medium through the liquid storage chamber 220, and the liquid working medium accumulated in the liquid storage chamber 220 can pass through the second support wall 222 of the capillary structure 20 and the lower flat plate portion 21 in time. The inside of the entire capillary structure 20 is replenished, so that the evaporation of the liquid working medium in the evaporation chamber 225 is not timely, and the liquid supply in the evaporation chamber 225 is insufficient to be dried or burned. At the same time, the liquid working medium in the evaporation chamber 225 absorbs heat and evaporates. After being in a gaseous state, due to the blocking of the second support wall 222 of the capillary structure 20, the vapor does not flow back into the liquid storage chamber 220 to generate heat leakage (ie, heat in the evaporation chamber 225 enters the liquid storage chamber 220, causing the performance of the evaporation portion 11 to decrease. Even if it fails, it can only flow along the vapor channel 227 to the vapor chamber 228 and into the vapor line 13 through the evaporation portion outlet 116 that communicates with the vapor chamber 228, which is more advantageous for improving the performance of the loop heat pipe 10. In addition, due to the capillary The structure 20 is supported between the cover plate 113 of the evaporation portion 11 and the bottom plate 110, and the capillary structure 20 itself has strong supporting strength, so that it can be added The compressive strength of the evaporation portion 11, therefore, the base 111 and the cover 113 of the evaporation portion 11 can be made of a thinner casing, thereby reducing 099128164 Form No. A0101 Page 10 / Total 22 Page 0992049521-0 201209366 Ο厚度 The thickness and weight of the evaporation portion 11 are reduced in manufacturing cost. The difference between the a in the second embodiment of the loop heat pipe of the present invention and the capillary lion in the first embodiment is that the structure 20a is also included. The strip portion is flattened at the top end. When the capillary side is clear in the evaporation portion n, the = plate portion 24 is respectively attached to the upper surface of the bottom plate and the cover plate; In this embodiment, the strip 113 is placed on the cover plate 113 to be in contact with the heat-generating electronic component as a heating region. The capillary structure b' in the third embodiment which is not the fresh-keeping tube of the present invention is different from the capillary structure 20a in the second embodiment in that it is formed between the flat plate portion 21 and the other flat plate portion 24. The vapor grooves are each circular. In the above, the invention conforms to the payment of the financial item, and the patent application is filed according to law.
