Abstract

【課題】従来の縦型ヒートパイプは、下部が温熱源の場合は冷媒液の循環が効果的に行えるが、上部が温熱源の場合には効率が悪く、活用されていなかった。【解決手段】従来の縦型ヒートパイプにウィックを取り付けた毛細管を挿入し冷媒液面を当該毛細管より上部にすることにより、毛細管現象による冷媒の上昇する力が内部のウィックにより強められ、また、上部の温熱源で気化した冷媒が冷媒液面を圧迫する力を用いて自発的に熱交換が行えるようにした。また、下部が温熱源の場合は毛細管外壁のウィックと壁面のウィックによるヒートパイプとして熱交換を行うことが可能である。【選択図】図１A conventional vertical heat pipe can effectively circulate a refrigerant liquid when the lower portion is a heat source, but is inefficient when the upper portion is a heat source, and has not been utilized. By inserting a capillary tube with a wick attached to a conventional vertical heat pipe so that the liquid level of the refrigerant is above the capillary tube, the upward force of the refrigerant due to capillary action is strengthened by the internal wick, and The vaporized refrigerant in the upper heat source presses the liquid surface of the refrigerant to allow spontaneous heat exchange. Moreover, when the lower part is a heat source, it is possible to perform heat exchange as a heat pipe with a wick on the outer wall of the capillary tube and a wick on the wall surface.

Description

この発明は従来の縦型ヒートパイプにウィック付毛細管を挿入し冷媒液面を当該毛細管より上部にすることにより、上部が温熱源の場合に毛細管により冷媒が一定方向に自発的に循環できるようにし、下部が温熱源の場合には従来のヒートパイプとして稼働するヒートパイプである。In this invention, a capillary tube with a wick is inserted into a conventional vertical heat pipe so that the liquid surface of the refrigerant is above the capillary tube , so that when the upper part is a heat source, the refrigerant can circulate spontaneously in a certain direction through the capillary tube. , is a heat pipe that operates as a conventional heat pipe when the lower part is a heat source.

従来の縦型ヒートパイプは地中熱を利用した融雪の用途でしか活用されていなかった。Conventional vertical heat pipes were used only for melting snow using geothermal heat.

縦型ヒートパイプは、下部が温熱源の場合は冷媒液の循環が効果的に行えるが、上部が温熱源の場合は冷媒が下降する力が暖められた冷媒が上昇しようとする力により弱められ効率が良くなかった。The vertical heat pipe can effectively circulate the refrigerant liquid when the lower part is the heat source, but when the upper part is the heat source, the downward force of the refrigerant is weakened by the upward force of the warmed refrigerant. It wasn't efficient.

従来のヒートパイプにウィックを取り付けた毛細管を挿入し冷媒液 面を当該毛細管より上部にすることにより、上部が温熱源の場合、毛細管現象による冷媒の上昇する力が内部のウィックにより強められ、また、上部の温熱源で気化した冷媒が冷媒液面を圧迫する力を用いて冷媒液が毛細管内を上昇する一定方向の流れを作り出すことにより自発的に熱交換が行えるようにした。また、下部が温熱源の場合は毛細管外壁のウィックによりウィックの表面積が通常のヒートパイプより増加した高効率ヒートパイプとなる。By inserting a capillary tube with a wick attached to a conventional heat pipe and raising the liquid level of the refrigerant above the capillary tube , when the upper part is a heat source, the upward force of the refrigerant due to the capillary phenomenon is strengthened by the internal wick. , the vaporized refrigerant in the upper heat source presses the liquid surface of the refrigerant, creating a unidirectional flow in which the liquid refrigerant rises in the capillaries, enabling spontaneous heat exchange. In addition, when the lower portion is a heat source, the wick on the outer wall of the capillary increases the surface area of the wick, resulting in a highly efficient heat pipe.

本発明により、ヒートパイプの温熱源が上部及び下部のいずれの場合においても効率の良い熱交換が行え、地中熱利用や高層ビル等の熱輸送等に応用できる。According to the present invention, efficient heat exchange can be performed regardless of whether the heat source of the heat pipe is in the upper part or the lower part, and it can be applied to geothermal heat utilization, heat transport in high-rise buildings, and the like.
