Description

553323 V. Creation instructions (1) [Creation area This creation is about a horizontal convection fan structure, the air inlet and outlet of which are connected through a horizontal airflow channel, and j = about the fan blade (centrifugal blower blade) to drive the horizontal a centrifugation The drum gains horizontal airflow in airflow channels of limited height. For the lice, according to the previous technology, most of the conventional fans use air inlets at the top and air outlets at the sides. Therefore, the fan must leave a space at the top for air. Therefore, the thickness of the fan cannot be effectively reduced, so it is not suitable for electronic devices, such as a notebook computer. 'Published in the Republic of China Patent Gazette Announcement No. 47 1 660, a new patent published on January 1, Republic of China, characterized in that the air inlet and outlet are formed on any two side walls of the base There is a difference in height between the air inlet and the air outlet. The first figure reveals a perspective view of the fan of Announcement No. 471660. The second figure discloses a partial cross-sectional elevation-body diagram of the fan of the announcement No. 4 7 16 6 0. The third figure is the schematic diagram of the fan used in the notebook computer under the announcement No. 471660. Referring to the first figure, an air inlet 11 and an air outlet 12 are provided on both sides of a housing base 10 of a fan 1. The air inlet 11 and the air outlet 12 have a height difference, which makes the air inlet 11 higher than Air outlet 1 2. Referring to the second figure, an axial propeuer blade 13 is disposed between the air inlet 11 and the air outlet 12. Due to the height difference between the air inlet 11 and the air outlet 12, the bottom plate of the base 10 is thicker at the air inlet 11 and thinner at the air outlet 12, so that there is a height difference between the two. Because the air inlet 11 and air outlet 12 are set high

553323 V. Creation instructions (2) t: Connection: t: The structure of the base 10 is complicated, and the height difference causes no wind and reduces airflow efficiency. At the same time, this height difference is obviously also :: ;;; 1. Therefore, the total thickness of the fan 1 does not correspond to the reduction of the overall thickness of the fan 1 itself and :: 2 1,;:-as shown in the figure, the axial-flow-type leaf 13 is vertically driven on the horizontal surface of the air inlet 1 1. Obviously, the vertical ΐ 2 ΐ 2 = ΐ horizontally reduces the water between the person's air outlet 11 and the air outlet 12 ^ /; 'L / ;, L >; Therefore, the air flow efficiency driven by the fan 1 is not good 0 Please refer to the third figure, the fan 1 is assembled in a notebook computer 2. The air inlet and air outlet 12 of the fan 1 only corresponds to one of the air inlet 21 and the air outlet 22 of a housing 20, so the note The heat generated by other electronic components in the type computer 2 cannot be properly discharged. In view of this, this creation improves the above-mentioned disadvantages. It connects the air inlet and the air outlet through a flat airflow channel correspondingly, and uses a centrifugal fan-type fan to drive the horizontal airflow, so as to increase the flow of airflow in the horizontal airflow channel. 〇 [Summary of the creation] The main purpose of this creation is to provide a horizontal convection fan structure, which includes an air inlet and an air outlet directly connected horizontally to reduce the airflow obstructions corresponding to the air inlet and the air outlet. Gain the effect of air flow. The secondary purpose of this creation is to provide a horizontal convection fan structure that uses a centrifugal fan-type fan blade to drive the horizontal airflow in a horizontal airflow channel.

The purpose of "utilization" is to provide a horizontal convection fan structure. The position of the inlet and outlet fan blades is deviated from the center of a shell seat and leans against the mouth, so that this creation has the effect of increasing horizontal air flow. in. ^ Created horizontal convection fan structure, the fan structure contains one and = centrifugal drum fan wheel. The shell seat is provided with an air inlet and an air outlet. The horizontal airflow is directly connected horizontally, and the centrifugal fan is placed in the horizontal airflow channel. The centrifugal fan wheel is selected to be formed at the center of the shell. Yes or no. [Description of creation] In order to make the above and other purposes, features, and advantages of the four creations clearer, ‘the preferred embodiment of the creation will be enumerated below, and described in detail with the accompanying drawings’. Fig. 2 illustrates an exploded view of the ancestor of the horizontal convection fan structure of the first preferred embodiment of the present invention. The fifth figure reveals the horizontal convection wind of the first preferred embodiment: a partially cutaway perspective view of the structure k. The sixth figure shows a schematic diagram of the horizontal flow t fan structure of the first preferred embodiment used in a notebook computer. t taxi. As shown in Figs. 4 and 5, the horizontal flow fan 3 of the first preferred embodiment of the present invention includes a housing base 30 and a centrifugal fan fan wheel 35. The case base 30 is made of a thermally conductive material, which can be attached to a heat source [CPU] for heat dissipation. The side wall of the shell base 30 is provided with two air inlets 3 丨 and two air outlets 32 ', and is equally spaced around the center of the shell base 30. The air inlet M and the air outlet 32 are directly connected horizontally and correspondingly through a horizontal airflow channel 34. The centrifugal fan fan wheel 35 is placed in the horizontal air passage 34, and the centrifugal fan fan wheel 35 is in the center.

V. Creative Instructions (4), > η corresponds to a vertical reference with the center 3 3 of the shell base 30, and each fan 3 can choose to have a cover plate (not marked) or no cover plate. 'If no cover is provided, the cover of the notebook computer can be used to form the cover. Please refer to the sixth figure, the fan 3 is assembled in a notebook computer 4, the air inlet 31 of the fan 3 corresponds to the inside of a casing 40, and the air outlet 32 of the fan 3 corresponds to the casing 40. The second air outlet 41, so the heat generated by other electronic components in the notebook computer 4 can be properly and smoothly discharged. Please refer to the fourth to sixth figures again. When the centrifugal fan fan wheel 3 5 starts to rotate, A part of the centrifugal airflow driven by the centrifugal fan fan wheel 35 is discharged from the air outlet 32 to the outside of the casing 40. Next, when the centrifugal fan fan wheel 35 is rotated for a period of centrifugal blast, a gas pressure difference will be generated between the air inlet 31 and the air outlet 32, so that the airflow will be between the air inlet 31 and the air outlet 32. Convection is generated along the horizontal airflow channel 34, so that heat generated by other electronic components (not shown) in the notebook computer 4 is discharged out of the casing 40 through the air inlet 31 and the air outlet 32.
