A waste heat recovery system is provided and relates to the technical field of servers. The waste heat recovery system includes an immersion box body, an evaporation box body, a heat exchanger, a circulating pipe and a first driving assembly, wherein the immersion box body is filled with a single-phase coolant; the evaporation box body is filled with a two-phase coolant and is provided with an extending portion that extends into the immersion box body and is in contact with the single-phase coolant; a water inlet and a water outlet of the heat exchanger are respectively communicated to different positions of the immersion box body. Based on that the pumpless driven cold and heat circulation flow of a coolant are achieved, the energy consumption of the system is reduced, and the energy utilization efficiency and the environmental protection performance are improved.

A cryogenic structure can include a cryogenic chamber that houses a plurality of circuits that operate and cryogenic temperatures, and a room temperature portion that houses a plurality of circuits that operate at non-cryogenic temperatures. The circuits can include computer chips, such as electrical or photonic chips, that are housed on movable structures that insertable into the cryogenic structure.

An immersion cooling system including a cooling tank, an immersion unit, and a baffle assembly is provided. The cooling tank has a receiving portion. The immersion unit is in the receiving portion and includes a boiler plate. The baffle assembly divides the receiving portion into an inner upper portion, an inner lower portion, and a peripheral portion. The boiler plate is in the inner lower portion, and a width of the inner upper portion is less than or equal to a width of the boiler plate.

A dual-inverter assembly is disclosed and includes an elongated base, a first power module, a second power module, an input copper busbar and two output copper busbars. The elongated base includes a first elongated sidewall and a second elongated sidewall opposite to each other and extended along a first direction. The first power module and the second power module are disposed on a first side and a second side of the elongated base along the first direction, respectively. The input copper busbar is spatially corresponding to the first elongated sidewall, and electrically connected to the first power module and the second power module. The two output copper busbars are spatially corresponding to the second elongated sidewall, and electrically connected to the first power module and the second power module, respectively, so as to achieve an optimized configuration.
