摘要

PPROBLEM TO BE SOLVED: To solve a problem in heat transfer promotion using a flow deflection plate, in which placing a single long flow deflection plate in the width direction of a heat radiation surface causes the heat transfer amount, which once increases immediately after the deflection plate, to deteriorate as it moves toward the downstream side (upper side) and eventually to become lesser than a case without the deflection plate, and to increase the heat transfer amount in a wider flow range. PSOLUTION: A plurality of deflection plates are arranged with an interval in the width direction of the heat radiating surface to significantly increase the heat transfer amount to more than a case with a single long flow deflection plate. The heat transfer deterioration is suppressed even in the downstream part of the flow deflection plate. In addition, a plurality of such rows of deflection plates can be incorporated in the height direction of the heat radiating surface with a certain interval, enabling wide range of facilitation of the heat radiation surface.

要解决的问题：为了解决使用导流板促进传热的问题，其中在散热表面的宽度方向上放置单个长导流板会引起传热量，一旦传热立即增加与没有偏转板的情况相比，在偏转板之后的情况下，随着向下游侧（上侧）移动而劣化，最终变小，并且在较宽的流动范围内增加了传热量。

解决方案：多个偏转板在散热表面的宽度方向上间隔开布置，从而与单个长流偏转板的情况相比，显着增加了传热量。即使在导流板的下游部分，也抑制了传热恶化。另外，可以在散热表面的高度方向上以一定间隔并入多个这样的偏转板行，从而可以大范围地促进散热表面。
