Abstract

The invention relates to a loop type heat pipe which is suitable for radiating heat of a heat source. The loop type heat pipe comprises a conduit, a first capillary structure, a second capillary structure and a working fluid arranged in the conduit, wherein the conduit is provided with a condensation section, a barrier section and an evaporation section, the evaporation section is suitable for touching the heat source in a heat conduction mode, and the barrier section is adjacent to the evaporation section; the first capillary structure is arranged on the inner surface of the conduit and between the condensation section and the barrier section; the second capillary structure is provided with a first part and a second part connected with the first part, and the first part is arranged on the inner surface of the conduit and extends to the barrier section from the evaporation section; the second part passes through the barrier section and extends towards the condensation section from the barrier section; and a gap is preserved between the first capillary structure and the second part of the second capillary structure and limits a compensated chamber.

Description

technical field [0001] The present invention relates to a heat pipe (Heat Pipe), specifically, a loop heat pipe (LoopHeat Pipe). Background technique [0002] The working principle of the heat pipe is to use the evaporation and condensation of the working fluid to transfer heat. First, the liquid working fluid evaporates into a gas by absorbing the heat emitted by the heating element adjacent to the evaporator of the heat pipe. When the gaseous working fluid is subjected to a slight pressure difference, it will flow to the condenser of the heat pipe, where it will condense into a liquid and release heat. The liquid working fluid condensed at the condensing end can be transported back to the evaporating end through the capillary structure on the inner wall of the cooked tube. Therefore, the heat pipe can be applied to heat dissipation of heat generating components. Patents related to heat pipes are, for example, US Patent No. 20080078530, and ROC Patent Nos. I248781 and 59...
