Embodiment Construction

[0045] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as Figure 1-4 A liquid-cooled plate heat exchanger with a square structure is shown, including a bottom plate 10 and a cover plate 20. The bottom plate 10 and the cover plate 20 are square structures, and the cover plate 20 and the bottom plate 10 are assembled together to form a square cavity. The cooling liquid (preferably water) flows in the cavity, and baffles 401-404 and ribs 501-504 are arranged on the bottom plate 10, and the baffles include the first baffle 401 located in the center of the bottom plate, surrounded by the second A second baffle 402 outside the first baffle 401, a third baffle 403 outside the second baffle 402, and a fourth baffle 404 outside the third baffle 403;

[0047] As preferred, such as Figure 1-3 As shown, the first baffle 401 includes four pieces, and each first baffle 401 includes two baffle wa...

Abstract

The invention provides a multi-outlet distributed liquid cooling plate heat exchanger. The multi-outlet distributed liquid cooling plate heat exchanger comprises a bottom plate and a cover plate, thebottom plate and the cover plate are of square structures, the cover plate and the bottom plate are assembled together to form a square cavity, and cooling liquid flows in the cavity. The multi-outletdistributed liquid cooling plate heat exchanger is characterized by comprising a liquid inlet and liquid outlets, wherein the liquid inlet and the liquid outlets are formed in the cover plate, the liquid inlet is formed in the center position of the cover plate, and the four liquid outlets are correspondingly formed in the four vertex angles of the cover plate. According to the multi-outlet distributed liquid cooling plate heat exchanger, the cold liquid flows in from the center area of the cover plate, when the cold liquid just enters the heat exchanger, the temperature is low, the temperature difference between the cold liquid and a heat source is large, the heat exchange capacity is high, the temperature of the heat source area can be more effectively controlled, so that outlets are evenly distributed, liquid distribution can be more even, and the heat exchange effect is better.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a plate heat exchanger in which a flow guiding structure and fins are combined. Background technique [0002] The plate heat exchanger is the heat exchanger with the highest heat exchange efficiency among all kinds of heat exchangers at present. It has the advantages of small space occupation and convenient installation and disassembly. It is composed of stamped concave-convex stainless steel plates. The concave-convex lines between two adjacent plates are combined at 180 degrees. Therefore, the concave-convex ridges between the two plates of the plate heat exchanger form staggered contact points, and the contact points After being combined by vacuum welding, the high-pressure staggered flow structure of the plate heat exchanger is formed. These staggered flow structures make the hot and cold liquids in the plate heat exchanger generate strong turbulence and a...
