Embodiment Construction

[0040] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] 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;

[0042] As preferred, such as Figure 1-2As 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-cooling tube plate type heat exchanger which comprises a base plate and a cover plate. The cover plate and the base plate are assembled together to form a fluid space. Abaffle plate and a cylindrical fin are arranged on the base plate. The baffle plate comprises a first baffle plate located at the center of the base plate, a second baffle plate encircling the outerside of the first baffle plate and a third baffle plate encircling the outer side of the second baffle plate. The heat exchanger comprises a fluid inlet and fluid outlets formed in the cover plate. Acold fluid inlet is formed in the center of a first square, and the two fluid outlets are separately formed in outer positions of parallel lines formed by two fourth baffle plates. The invention aimsto provide a center diffusing type water cooling plate. A refrigerant inlet / outlet mode of a common water cooling plate is changed by the water cooling plate, the flow equalizing property of a refrigerant in the cold plate is improved by additionally arranging the baffle plate, and the heat-dissipating characteristic of the water cooling plate is improved by arranging column ribs.

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...
