  • Patent number: 12385655
    Abstract: An indirect evaporative cooling air conditioner is provided, which includes a housing, multiple partition plates located in the housing and at least two heat exchangers arranged side by side. The multiple partition plates and the at least two heat exchangers separate the housing into multiple indoor air flow passages and multiple outdoor air flow passages, each heat exchange has a first heat exchange flow passage and a second heat exchange flow passage crosswise and independently arranged, the indoor air flow passages are in communication with the first heat exchange flow passages to form an indoor circulation passage, the outdoor air flow passages are in communication with the second heat exchange flow passages to form an outdoor circulation passage, and the fluid in the indoor circulation passages exchange heat with the fluid in the outdoor circulation passages through the at least two heat exchangers.

  • Patent number: 12160977
    Abstract: A liquid cooled plate and an electronic computing device are provided. The liquid cooled plate includes multiple channels communicated in sequence, and adjacent channels are communicated via a communicating portion. Multiple partitions divide each of the channels to multiple flow passages, and a part of each of the partitions extends into the communicating portion, and lengths of the multiple partitions extending into the communicating portion gradually increases or decreases according to a preset rule. With this arrangement, the coolant can be collected and redistributed before entering the next channel, which is more conducive to the uniform distribution of the coolant, thereby improving the overall heat exchange capacity of the liquid cooled plate, and thus can better meet the actual usage requirements.

  • Publication number: 20220369507
    Abstract: A cooling device includes a cooling plate and a buffer portion, a flow passage is formed in the cooling plate, and the buffer portion is arranged on the cooling plate. An inlet buffer zone and an outlet buffer portion are defined in the buffer portion, liquid flows into the flow passage through the inlet buffer zone and flows out of the flow passage through the outlet buffer portion. The liquid flows into the flow passage through the buffer portion, and the buffer portion can reduce the flow resistance of the liquid flowing into the flow passage. The liquid in the flow passage also flows out through the buffer portion, and the buffer portion can also reduce the flow resistance of the liquid flowing out of the flow passage.
