Loop type heat pipe

Abstract

The invention provides a loop type heat pipe. The loop type heat pipe comprises a loop pipe body and an evaporation cavity, wherein the evaporation cavity comprises a first containing chamber, a second containing chamber and a third containing chamber, the first containing chamber, the second containing chamber and the third containing chamber communicate with one another, the first containing chamber comprises a first liquid storage area, the second containing chamber comprises at least one backflow prevention flow channel, the third containing chamber comprises a second liquid storage area,and the third containing chamber is in contact with a heat source of the outside; and the first liquid storage area and the second liquid storage area are arranged so that water cooling liquid in thesecond liquid storage area can be rapidly and completely consumed, the water cooling liquid in the first liquid storage area can flow to the second liquid storage area to be used as adjustment. According to the loop type heat pipe, the back flowing of the water cooling liquid can be avoided, and air burning of a heated cavity can be prevented.

Description

technical field [0001] The present invention relates to a loop-type heat pipe, in particular to a loop-type heat pipe with a compensation chamber additionally storing water-cooling liquid. Background technique [0002] With the rapid development of computers and various electronic products, the convenience brought by them has made modern people develop the habit of using them for a long time, but the heat generated by computers and various electronic products during long-term operation The disadvantage of not being able to disperse in time accordingly also comes with it. So the loop heat pipe was born accordingly. [0003] The traditional loop heat pipe has a heating cavity and a pipeline connected to the heating cavity. The heating cavity and the pipeline together define a loop flow channel, and the water-cooling liquid flows in the loop flow channel. Ideally, the water-cooled liquid in the heated cavity advances toward an outlet of the heated cavity along a specific circ...

Problems solved by technology

However, a disadvantage of the traditional loop heat pipe is that when the water-cooled liquid in the heated cavity changes from a liquid state to a gaseous state when heated, the gaseous water-cooled liquid is not easy to be controlled, and may continue to flow to one side of the heated cavity. counter flow

[0004] In addition, another disadvantage of the traditional loop heat pipe is that when the water-cooling liquid in the heating chamber is heated higher than expected, the water-cooling liquid will be evaporated in a short time. In the case of condensation cooling and lack of water coolant that is not circulated back to the heated cavity, it will lead to a situation similar to empty fire, making the loop heat pipe overheated and unable to assist heat dissipation
