Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a transport heat amount control device for a heat transport device comprising a large number of heat pipes.

(Prior Art) The present applicant previously combined a plurality of heat pipes 01 into a bundle as shown in FIG. Condensing section 01b and evaporating section 01a of other adjacent heat pipes 01
We proposed a heat transport device in which the heat transport devices are arranged adjacent to each other and overlapped in the length direction. (Special application 1986-
(Refer to JP-A-61-237994 (No. 76757)) (Problem to be solved by the invention) In the above heat transport device, the supply temperature on the heat source side was adjusted according to the change in the load on the heat utilization side, so the time There was a problem that the delay was large and that the amount of transported heat could not be adjusted continuously and accurately over a wide range from full load to almost no load on the heat utilization side.

(Means for solving the problem) The present invention was proposed to solve the above problem, and its gist is to combine a plurality of heat pipes into a bundle and to arrange them adjacent to each other. In a heat transport device in which heat pipes are arranged overlappingly in the length direction, the heat pipes are arranged in multiple rows and stages in parallel at predetermined intervals and facing each other in the middle of the length direction of the heat transport device. A connected heat pipe element having heat pipes arranged in parallel in multiple rows and multiple stages within the predetermined interval is movably interposed via a moving means, and the heat pipes of the connected heat pipe element and There is provided a transport heat amount control device in a heat transport device, characterized in that the overlapping area with the heat pipes facing each other at the predetermined interval can be adjusted by moving the connected heat pipe elements.

(Function) Since the present invention has the above configuration, by moving the connected heat pipe element using a moving means and adjusting the overlapping area between this heat pipe and a heat pipe facing each other at a predetermined distance, Controls the amount of heat transported.

(Embodiment) An embodiment of the present invention is shown in FIG. 1, in which 1 is a heat transport device, in which a plurality of heat pipes 2 are combined into a bundle, and adjacent heat pipes 2 are arranged in the longitudinal direction. They are arranged in an overlapping manner, and their outer circumferences are covered with an outer skin 3 via a heat insulating material. and,
One end A of this heat transport device 1 extends to a heat source, and the other end B
extends to the heat utilization side. A transport heat amount control device 4 is interposed midway in the length direction of this heat transport device 1 . Inside the casing 5 of the transport heat amount control device 4, the heat pipes 2 are arranged in parallel in multiple rows and stages (7 rows and 3 stages in the figure) facing each other at a predetermined interval. pipe 6
The connected heat pipe elements 7 are arranged in parallel in multiple rows and multiple stages (8 rows and 3 stages in the figure).
is interposed. The heat pipes 6 of the connected heat pipe element 7 are made longer than the above-mentioned predetermined interval, and are supported by a metal fitting 8 at their central portions. The connecting heat pipe element 7 has a shaft 9 fixed to a metal fitting 8, which is connected to a stepping motor (not shown),
The heat pipe 6 rotates around the shaft 9 by being driven manually or by a drive device such as an oil motor or an air motor, and rotates so that the heat pipe 6 is parallel to both heat pipes 2 facing each other at a predetermined interval. When the heat pipe 6 is connected, each end of the heat pipe 6 overlaps the heat pipe 2a communicating with the heat source side A and the end of the heat pipe 2b communicating with the user side B with a maximum area to transfer the maximum amount of heat from the heat source side A to the user side. Can be transported to B.
By rotating the connected heat pipe element 7 from this state to reduce the overlapping area, the amount of heat transported can be continuously reduced.

FIG. 2 shows a second embodiment of the invention. The connected heat pipe elements 7 include multiple rows that communicate with the heat source side A, multiple rows that may overlap with the multiple stages of heat pipes 2a, multiple rows that communicate with the multiple stages of heat pipes 21a and the usage side B, and multiple stages of heat pipes 2b. Multiple rows and multiple stages of heat pipes 21b that may overlap, and these heat pipes 21a, 21b.
It consists of tubular metal fittings 22a and 22b to which are fixed.
From the upper end of the tubular fittings 22a, 22b, the round bar 23a
23b is inserted and retracted freely, and these round bars 23
Links 24a and 24b are pivotally attached to the upper ends of a and 23b via pins 25a and 25b. The links 24a and 24b are pivotally connected to each other by a pin 26 in the middle thereof, and the links 24a and 24b are
The upper ends of a and 24b are pivotally connected to nuts 28a and 28b via pins 27a and 27b. These nuts 28a, 28b are screwed into opposing male threads 30a, 30b of the threaded rod 29, and
A handle 31 is wedged at one end of the handle 9. The rest of the structure is the same as that of the first embodiment shown in FIG. 1, and corresponding members are given the same reference numerals.

Therefore, when the handle 31 is rotated, the threaded rod 29 rotates, and accordingly, the nuts 28a, 28
b move equidistantly in opposite directions. As a result, the links 24a, 24b rotate around the pin 26 in opposite directions, and the pins 25a, 24b rotate in opposite directions.
5b, the tubular fitting 22 via the round bars 23a, 23b
Heat pipes 21a, 2 fixed to a, 22b
1b are moved an equal distance in opposite directions. By adjusting the overlapping area of the heat pipes 21a, 21b and the heat pipes 2a, 2b,
The amount of heat transferred can be adjusted, and heat is transferred from the left end, ie, the condensation end, of the heat pipe 2a to the right end, ie, the evaporation end, of the heat pipe 21a, and then
The heat pipe 2b is transferred from the right end, ie, the condensation end, to the right end, ie, the evaporation end, of the heat pipe 2b.

In addition, if an auxiliary heat conductive medium is enclosed in the case 5, the heat pipes 2a, 2b, 22a, 22b
It is possible to control the decrease in heat transport efficiency due to poor contact between the two.

(Effects of the invention) In the present invention, in a heat transport device in which a plurality of heat pipes are combined into a bundle and adjacent heat pipes are arranged so as to overlap in the length direction, the heat transport device is A connection formed by arranging the heat pipes in parallel in multiple rows and stages facing each other at predetermined intervals in the middle of the length direction, and arranging the heat pipes in parallel in multiple rows and stages within the predetermined intervals. The heat pipe element is movably interposed via a moving means, and the overlapping area between the heat pipe of the connected heat pipe element and the heat pipe facing each other at the predetermined interval can be adjusted by moving the connected heat pipe element. Therefore, by moving the connected heat pipe elements using a moving means,
By adjusting the overlapping area between the heat pipe of the connected heat pipe element and the heat pipe facing each other at a predetermined interval, the amount of heat transferred from the heat source side to the user side can be easily and quickly adjusted. Therefore, it is possible to quickly respond to changes in the load on the user side, and to adjust the amount of transported heat continuously and accurately from full load to partial load without reducing heat transport efficiency.
