Title:
THIN PLATE TYPE LOOP HEAT PIPE
Document Type and Number:
WIPO Patent Application WO/2022/183793
Kind Code:
A1
Abstract:
The present invention relates to the technical field of heat dissipation devices, and in particular to a thin plate type loop heat pipe, comprising a housing. The housing comprises a first housing plate and a second housing plate that cover each other, and the edges of the first housing plate and the second housing plate are connected in a sealing mode; an evaporation chamber, a steam channel, a condensation chamber, a liquid channel, a compensation chamber, and an auxiliary fluid channel are formed between the first housing plate and the second housing plate; the compensation chamber stores a liquid phase working medium; the evaporation chamber is provided with a first capillary structure that divides the evaporation chamber into a first steam chamber and a second steam chamber; the second steam chamber is located between the first steam chamber and the compensation chamber; the second steam chamber is separated from the compensation chamber by means of the first capillary structure; the first steam chamber and the second steam chamber are respectively communicated with the condensation chamber by means of the steam channel and the auxiliary fluid channel; and the condensation chamber is communicated with the compensation chamber by means of the liquid channel. All the components of the loop heat pipe are integrated between the two housing plates, and thus, a manufacturing process is simpler and more efficient. The second steam chamber and the auxiliary fluid channel are added, and thus, a heat transfer temperature difference of the loop heat pipe can be reduced.
