Embodiment Construction

[0051] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0052] 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;

[0053] 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 uniform temperature control method for a liquid-cooled plate heat exchanger, which includes a bottom plate and a cover plate, the highest temperature and the lowest temperature of the four outlet temperatures detected, and when the difference between the highest temperature and the lowest temperature exceeds a certain value, control The device automatically controls the opening of the valve at the outlet with the lowest temperature to decrease, and the opening of the valve at the outlet with the highest temperature to increase, so that the liquid flow at the outlet with the lowest temperature decreases and the liquid flow at the outlet with the highest temperature increases. By adjusting the flow rate of the liquid at the lowest and highest temperature outlets, the heat exchange of liquids participating in the lowest and highest temperature sides can be adjusted. In the present application, by adjusting the liquid flow rate, the overall output temperature can be kept balanced, and the local temperature can be avoided from being too high or too low.

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 guide 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 ach...
