Patent attributes
The present invention discloses a two-phase immersion-cooling micro-grooved boiler, which is mainly used for heat dissipation of heat generating objects. The boiler comprises a heat transfer member and a capillary layer positioned in tight contact with a surface of the heat transfer member. The capillary layer has an array of micro-grooves which divides the capillary layer into a plurality of heat dissipating units. The bottom surface of the micro-grooves is coated with a thermal resistance layer. While the boiler operates, the working liquid can flow into the heat dissipating units from the sidewall of the micro-grooves without being blocked from contact with the heat transfer member by boiling-triggered bubbles. As a result, dry-out of the heat transfer member can be avoided, thereby improving the heat exchange efficiency of the boiler and the flow-back rate of the working fluid.
