Abstract: The present invention discloses an openable and closeable condensing apparatus, which is particularly applied in a two-phase liquid immersion cooling system. When servers start to operate, a large amount of heat will be dissipated from servers. The coolant is vaporized into a rising coolant vapor by absorbing heat dissipated from servers. Upon contact with a condenser, the coolant vapor is condensed back into a cooling liquid that is returned to the coolant-containing tank. By the heat exchange cycle in which heat dissipated from serves is absorbed by the coolant, servers can be maintained at a normal working temperature. However, in the process of condensation, the rising coolant vapor tends to scatter in all directions resulting in a failure to condense all of the coolant vapor. Therefore, the uncondensed coolant vapor will cause the pressure in the system to gradually rise, which eventually leads to an ineffective cooling of servers.

Abstract: 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.

Abstract: Provided is a cabinet, which comprises a top cover, four tri-layer side walls and a tri-layer base. The top cover, the four tri-layer side walls and the tri-layer base are connected with and fixed to one another by aluminum extrusion fixing assemblies. The tri-layer structure includes an inner honeycomb panel, a middle strengthening assembly and an outer wall panel. The middle strengthening assembly is formed by a plurality of horizontal tension rods and a plurality of vertical tension rods intersecting. The inner honeycomb panel has a hexagonal-celled hollow geometric structure, which confers the panel with such properties as high pressure-endurable strength, light weight, excellent rigidity and high structural stability. In addition, the hexagonal hollow cells can also make the honeycomb panel capable of better thermal insulation by preventing the air flow.

Abstract: The present invention discloses a three-chambered constant pressure apparatus for liquid immersion cooling of servers. The apparatus comprises a housing within which two partitions are disposed. The two partitions divide the housing into a first chamber, a second chamber and a third chamber. A coolant is maintained within the first chamber, and an isolating liquid is maintained within the second chamber and the third chamber. At least one heat-generating device is submerged within the coolant maintained within the first chamber. During the operation of a server, a coolant is heated to a boiling point temperature generating a coolant vapor that causes the pressure in chambers to rise. By adjusting the air pressure in chambers prior to use, the rising pressure in chambers caused by the coolant vapor can be efficiently relieved.

Abstract: The present invention discloses a one-chambered constant pressure apparatus for liquid immersion cooling of servers, which are submerged within a non-conductive coolant maintained in the apparatus. When servers start to operate, a large amount of heat will be dissipated from servers. The coolant is vaporized into a coolant vapor by absorbing heat dissipated from servers, which enables servers to be cooled. The coolant vapor is condensed into a cooling liquid by a condenser. However, in the process of condensation, the rising coolant vapor tends to scatter in all directions resulting in a failure to condense all of the coolant vapor. Therefore, the uncondensed coolant vapor will cause the pressure in the apparatus to gradually rise, which eventually leads to the ineffective cooling of servers.
