Flat-plate loop heat pipe

Abstract

The invention discloses a flat-plate loop heat pipe. A first liquid aspirating core and a first supporting frame form an evaporation chamber; and a second liquid aspirating core and a second supporting frame form a compensated chamber. Therefore, the problems that the conventional loop heat pipe is difficult to start under low-wattage heat sources and the first liquid aspirating core is dried up are solved.

Description

technical field [0001] The present invention is related to the heat fransfer element, and more specifically refers to a flat-plate loop heat pipe. Background technique [0002] A loop heat pipe (LHP) is an effective heat dissipation element; a general loop heat pipe includes an evaporator, a vapor line, a condenser and a liquid line. line), and the above components communicate with each other to form a circuit; the circuit is still filled with working fluid, and the evaporation part has a capillary structure connected to a heat source; a compensation chamber is provided between the liquid pipeline and the capillary structure in the evaporation part (compensation chamber). When the evaporation part of the loop heat pipe absorbs the heat from the heat source, the working fluid in the loop heat pipe also absorbs the heat from the heat source and evaporates to form steam; the steam flows through the steam pipeline through the condensation part, and releases heat and condenses i...

Problems solved by technology

[0004] In view of this, aiming at the shortcomings of the above-mentioned existing devices, the main purpose of the present invention is to provide a flat-plate loop heat pipe, which can also allow the formed vapor to escape to the evaporation chamber under the condition of a low-wattage heat source, and There are no obstacles in the evaporation chamber, so the flow resistance of the steam is small, and it will not cause excessive local pressure inside the evaporation chamber and make it difficult to start.
