Patent JP-H03134493-A (JP)
Title: Heat pipe
Inventor: SOTANI JIYUNJI
IPC: F28D15/02
Filed: 1989-10-18
Abstract: PURPOSE:To increase the maximum transportation capacity of heat under gravity-free state by installing into a container an inner pipe which runs continuously from a heating section to a cooling section by way of an insulation section with both ends opened and forming a wick layer in the insulation section between a groove and the inner pipe inside said container. CONSTITUTION:The steam which has evaporated an actuation liquid at a heating section 'a', moves to a cooling section (c), passing through an inner pipe 2. The liquid condensed at the cooling section (c) is carried into the heating section 'a' by a wick layer 3 in grooves 11 of a container 1 and an insulation section (b). Therefore, the flow of gas-liquid is perfectly separated by the inner pipe 2 in the opposite direction so that they may not come in contact with each other, which m makes it possible to prevent the drop in the maximum heat transportation capacity. When the actuation liquid which has been carried over to the heating section 'a', is evaporated, the pres sure of steam produced by vaporization expansion does not act on the actuation liquid in a reverse flow direction flowing in the region of the insulation section (b) at the heating section 'a'. Moreover, when the steam is flowing in a space of the heating section 'a' of the container 1 in the direction of its end 1a as marked with an arrow 'A', the actuation liquid is promoted to flow in a forward direction, thereby increasing the heat transportation capacity at the maximum.
