Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/213131
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a cooling device, comprising a container, a foaming device, and a circulation device. A cooling cavity is provided in the container, and a cooling liquid is contained in the cooling cavity to cool a heat-generating object; a part of the structure of the foaming device is immersed in the cooling liquid, and can generate bubbles, and the bubbles can rise in the cooling liquid to be attached to the surface of the heat-generating object needing to be cooled; the circulation device is connected to the container, and is configured to collect and condense vaporized cooling liquid and then re-convey the condensed cooling liquid into the cooling cavity. The foaming device is arranged to generate a bubble cluster to flush the surface of a heat-generating element, so that the bubbles can replace a vaporization core to accelerate evaporation of liquid near the heat-generating element, and the superheat degree of the surface of the heat-generating element can be reduced. Moreover, the bubble cluster may assist in separation of the vaporization core on the surface of the heat-generating element, thereby improving the upper limit of the heat exchange capability, preventing or delaying occurrence of film boiling, increasing the critical heat flux density, further improving the phase-change heat exchange cooling capacity of an apparatus, and meeting high-strength heat dissipation requirements.
