【発明の詳細な説明】 〔産業上の利用分野〕 本発明はヒートパイプによる冷却機構に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a cooling mechanism using a heat pipe.

却フィン3,3・・・の間隔も同じに設定されていた。Conventionally, as shown in FIG. 3, a plurality of heat pipes 2 of the same length each have a plurality of cooling fins 3, 3, . . . in a cooling section.
When the cooling portions of the heat pipes 2a, 2b, and 2c are arranged in series from the inflow side to the outflow side of the cooling wind W in the wind tunnel 4, the cooling fins 3, 3, . . . The number of cooling fins 3, 3, . . . was the same, and the intervals between adjacent cooling fins 3, 3, . . .
また1は発熱体である。Further, 1 is a heating element.

一化ができないという欠点があった。As described above, conventionally, when heat pipes of the same length each having a plurality of cooling fins are arranged in a wind tunnel in series from the inflow side to the outflow side of the cooling air in the cooling section, the wind tunnel as shown in FIG. The wind speed within the wind tunnel is highest at the center of the wind tunnel and decreases as it gets closer to the wall of the wind tunnel, so the cooling efficiency of the cooling part of the heat pipe located at the center of the wind tunnel is highest, and Since the cooling efficiency of the cooling portion of the heat pipe is reduced, there is a drawback that the cooling efficiency cannot be made uniform.
本発明の目的は前記課題を解決したヒートバイプによる
冷却機構を提供することにある。An object of the present invention is to provide a cooling mechanism using a heat vip that solves the above problems.
上述した従来のヒートパイプによる冷却機構に対し、本
発明は冷却効率の均一化を図るという相違点を有する。The present invention differs from the conventional cooling mechanism using a heat pipe described above in that it aims to equalize cooling efficiency.

く設定したものである。In order to achieve the above object, the present invention has a plurality of heat vibrators of the same length each having a plurality of cooling fins at one end and a heating element attached to the other end, and the cooling portion is placed in a wind tunnel so that cooling air flows into the wind tunnel. In a cooling mechanism that is arranged in series from the side to the outflow side, heat pipes with fewer cooling fins are placed on the inlet side of the cooling air, and heat pipes with more cooling fins are placed closer to the outflow side of the cooling air. Furthermore, the arrangement of the cooling fins of each heat pipe is such that the distance between adjacent cooling fins becomes narrower as they get closer to the wall of the wind tunnel, and the distance between adjacent cooling fins becomes wider in the center of the wind tunnel. This is the setting.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

The cooling parts of a plurality of heat pipes 2a, 2b, 2c of the same length each having a heating element 1 attached to the other end are placed in the wind tunnel 4 from the inflow side of the cooling air W to the outflow side. When arranged in series, the heat pipes 2a having a smaller number of cooling fins 3 are arranged on the inflow side of the cooling air, and the heat pipes 2b and 2c having a larger number of cooling fins 3 are arranged closer to the outflow side of the cooling air. Furthermore, each heat pipe 2a, 2
The arrangement of the cooling fins 3 in FIGS. b and 2c is such that the distance between adjacent cooling fins becomes narrower closer to the wall of the wind tunnel, and the distance between adjacent cooling fins is set wider in the center of the wind tunnel.
