Problems solved by technology

The structure is relatively complicated and because the rubber gasket is easy to age at high temperature and loses its sealing effect, resulting in a large amount of fluid leakage, which endangers the safety of the equipment; in addition, the rubber gasket also has compatibility problems with the fluid. It cannot be used in corrosive fluids, which limits the range of use of the plate heat exchanger; in addition, due to the high degree of turbulence in some areas of the plate heat exchanger, when the fluid flows, the exchange Th

Abstract

The invention discloses a welding plate heat exchanger. The welding plate heat exchanger comprises a shell and a heat exchange plate set inside the shell; the shell is rectangular and horizontally arranged; large half round channels are arranged at the two ends of the shell; the top of one of the large half round channels is provided with a cooled medium inlet; the top of the other large half round channel is provided with a cooled medium outlet; a small half round channel is arranged on the shell wall of the upper side, close to the cooled medium inlet, of the shell; the top of the small halfround channel is provided with a cooling medium outlet; a small half round channel is arranged on the shell wall of the lower side, close to the cooled medium outlet, of the shell; the top of the small half round channel is provided with a cooling medium inlet; the heat exchange plate set is formed by overlapping a plurality of heat exchange plate pair layer by layer; and each heat exchange platepair comprises an upper heat exchange plate and a lower heat exchange plate which are opposite. The effects that the welding plate heat exchanger can bear high temperature, is resistant to corrosion,high in intensity, not prone to deforming, not prone to being blocked and high in heat exchange efficiency can be achieved.

Description

technical field [0001] The invention relates to a plate heat exchanger, in particular to a welded plate heat exchanger. Background technique [0002] Heat exchangers (also known as heat exchangers or heat exchange equipment) are used to transfer heat from hot fluid to cold fluid, and can be divided into coil-plate heat exchangers, plate heat exchangers, and shell-and-tube heat exchangers according to their structure . The traditional plate heat exchanger is composed of a group of rectangular thin metals arranged in parallel and tightly assembled on the bracket. The edges of the adjacent plates are provided with rubber gaskets, and a sealed fluid channel is formed between the plates after compression, and the size of the channels can be adjusted by the thickness of the rubber gaskets. On the four corners of each plate, a circular hole is opened, and a pair of circular holes communicate with the flow channels between a group of plates, and the other pair of circular holes pr...
