[0002] A plate heat exchanger that uses fluid to distribute evenly is a device used for heat transfer, usually used to transfer heat from one fluid to another, such as transferring heat from hot water or steam to cooling water or air. This type of plate heat exchanger separates the heat source and cooling medium through a plate structure, and uses the space between the plates to achieve heat transfer.

[0003] After searching, the Chinese patent document with announcement number CN216132336U discloses a plate heat exchanger plate with unequal cross-sectional areas of fluid channels, which belongs to the field of plate heat exchanger production equipment. The key points of its technical solution include a heat exchange plate body, a gripping groove is provided in the middle of the left and right sides of the heat exchange plate body, and two evenly and symmetrically distributed inlets and outlets are provided on the left and right sides of the front end surface of the heat exchange plate body. A heat transfer area is provided in the middle of the front end surface of the heat exchange plate body, and a diversion area and a guide area are provided on the left and right sides of the heat transfer area from the inside to the outside. A plurality of evenly distributed heat transfer protrusions are fixedly connected inside the heat transfer area. The heat transfer protrusions and the heat transfer grooves increase the cross-sectional area of ​​the fluid channel, and the quality of heat exchange is improved. The width and depth of the upper opening of the V-shaped groove are different, so that the flow rate of the plate heat exchanger plate is unequal, and the channel space formed between the plate heat exchanger plates is fully utilized, thereby improving the heat exchange efficiency, reducing the cost, and effectively avoiding waste.

[0004] The working principle of the above patent specification mentions that "after the heat exchange plate body 1 is installed, the medium enters and exits through the inlet and outlet 102 for exchange, and a sealing gasket groove 1021 is opened on the outside of the inlet and outlet 102, so that the sealing gasket can be conveniently placed in the sealing gasket groove 1021, so that the sealing performance between two adjacent heat exchange plate bodies is enhanced, and a heat transfer protrusion 1031 and a heat transfer groove 1032 are arranged in the middle of the heat transfer area 103 in a "wave" shape, which increases the cross-sectional area of ​​the fluid channel and improves the quality of heat exchange.
