Embodiment Construction

[0049] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] 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;

[0051] 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 liquid-cooled plate heat exchanger with variable intervals, including a bottom plate and a cover plate, the bottom plate and the cover plate are square structures, the cover plate and the bottom plate are assembled together to form a square cavity, and the cooling liquid flows in the cavity. A baffle and a rib are arranged on the bottom plate, and the baffle includes a first baffle located at the center of the bottom plate, a second baffle surrounded outside the first baffle, and a second baffle surrounded by the second baffle. The third baffle on the outside and the fourth baffle surrounding the outside of the third baffle, a plurality of ribs are arranged inside the first baffle; the ratio of the length of the baffle wall between the first interval and the first baffle > The ratio of the length of the baffle wall of the second compartment to the baffle wall of the second baffle > The ratio of the length of the baffle wall of the third compartment to the baffle wall of the third baffle > The ratio of the baffle wall of the fourth compartment to the baffle wall of the fourth baffle ratio of lengths. Through the change of the ratio of the space to the wall of the baffle plate, the more the space diffuses to the outside, the smaller the space is, which can improve the heat exchange effect and enhance the heat transfer.

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...
