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 an interval-variable liquid cooling plate heat exchanger which comprises a bottom plate and a cover plate, wherein the bottom plate and the cover plate are of a square structureand are assembled together to form a square cavity, cooling liquid flows in the cavity, and baffle plates and fins are arranged on the bottom plate; the baffle plates comprise a first baffle plate positioned in the center of the bottom plate, a second baffle plate surrounding the first baffle plate, a third baffle plate surrounding the second baffle plate and a fourth baffle plate surrounding thethird baffle plate; a plurality of ribs are arranged in the first baffle plate; and the ratio of the first interval to the baffle plate wall length of the first baffle plate, the ratio of the secondinterval to the baffle plate wall length of the second baffle plate, the ratio of the third interval to the baffle plate wall length of the third baffle plate, and the ratio of the fourth interval tothe baffle plate wall length of the fourth baffle plate are from big to small. By changing the ratios of the intervals to the baffle plate walls, the intervals are smaller if diffusion to the outsideis further, so that heat exchange effect is improved, and heat transfer is strengthened.

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...
