Embodiment Construction

[0043] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044]Such as Figure 1-3 A water-cooled plate heat exchanger shown includes a base plate 10 and a cover plate 20, the cover plate 20 and the base plate 10 are assembled together to form a cavity, and a cooling fluid (preferably water) flows in the cavity, and the base plate 10 is provided with The baffles 401-404 and cylindrical ribs 501, 502, the baffles include a first baffle 401 located at the center of the base plate, a second baffle 402 surrounding the first baffle 401, and a second baffle surrounded by the second baffle The third baffle 403 outside 402;

[0045] As preferred, such as Figure 1-2 As shown, the first baffle plate 401 includes four pieces, and intervals are set between adjacent first baffle plates 401, and there is a vertical relationship between adjacent first baffle plates 401, and the extension lines of the four first...

Abstract

The invention provides a water-cooled tube-sheet heat exchanger with variable spacing between cylindrical fins, which includes a base plate and a cover plate, the cover plate and the base plate are assembled together to form a fluid space, and a baffle plate and cylindrical fins are arranged on the base plate, so that The baffle includes a first baffle located at the center of the substrate, a second baffle surrounding the first baffle, and a third baffle surrounding the second baffle; between the second baffle and the third baffle Cylindrical fins are arranged between them, outward from the center of the substrate, the farther away from the center of the substrate, the farther the distance between adjacent cylindrical fins is. The purpose of the present invention is to keep the fluid flow rate relatively stable by setting the distance between adjacent cylindrical fins so that the overall heat transfer can be relatively uniform, and avoid local uneven heating, causing local premature damage .

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a plate heat exchanger with a flow guide structure combined with column ribs. 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 concave-convex stainless steel plates formed by stamping. The concave-convex lines between the 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 resistant staggered flow structure of the plate heat exchanger is formed. These staggered flow structures make the cold and hot fluids in the plate heat exchanger generate strong turbul...
