Title:
CAPILLARY PHASE-CHANGE COOLER AND INSTALLATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/137266
Kind Code:
A1
Abstract:
A capillary phase-change cooler (10) for dissipating heat from a power device (20) comprises a cooler main body (100) and a capillary liquid-absorbent layer (200). The cooler main body (100) has a cooling cavity (110) and a heat dissipation opening. A liquid reservoir portion for containing a cooling liquid (30) is arranged at the bottom of the cooling cavity (110). The heat dissipation opening and a heat dissipation wall of the power device (20) cooperate to seal the cooling cavity (110). The capillary liquid-absorbent layer (200) is provided at the heat dissipation opening and firmly attaches to the heat dissipation wall of the power device (20). One end of the capillary liquid-absorbent layer (200) extends into the liquid reservoir portion. In the capillary phase-change cooler (10), the capillary liquid-absorbent layer (200) is directly provided at the heat dissipation wall of the power device (20), such that the heat dissipation wall of the power device (20) has a constant surface temperature, thereby improving heat dissipation efficiency.
