[0002] The structural form of the existing detachable plate heat exchanger is that the plates are sealed with sealing rubber pads to form half-sheet pairs, and the multiple half-sheet pairs are sealed with sealing rubber pads to form a plate bundle. Due to the limitations of its own structure, the operating pressure does not exceed 2.5MPa, and the operating temperature does not exceed 180°C. In addition, since the plates are completely sealed by sealing rubber pads, there is also a compatibility problem between the

Abstract

The invention relates to a semi-welded plate heat exchanger which comprises a fixed clamping plate, a movable pressing plate, an upper guide rod, a lower guide rod, a supporting column, semi-welded plate pairs, sealing gaskets and a clamping bolt pair. The fixed clamping plate, the movable pressing plate, the upper guide rod, the lower guide rod and the supporting column form the frame of the heat exchanger. A plurality of semi-welded plate pairs are assembled by the sealing gaskets to form a plate which is arranged between the fixed clamping plate and the movable pressing plate and fixed by the clamping bolt pair. A plurality of semi-welded plate pairs at the plate are sealed by the sealing gaskets. Meanwhile, the sealing position of a plate A and a plate B of the semi-welded plate pairs adopts the structure of two-sided laser welding, so as to effectively overcome the deformation of the plate pairs during welding and eliminate the deformation stress during welding. The heat exchanger has the advantages of simple and reasonable structure, convenience in use and good heat exchanging effect.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a detachable semi-welded plate heat exchanger. Background technique [0002] The structural form of the existing detachable plate heat exchanger is that the plates are sealed with sealing rubber pads to form half-sheet pairs, and the multiple half-sheet pairs are sealed with sealing rubber pads to form a plate bundle. Due to the limitations of its own structure, the operating pressure does not exceed 2.5MPa, and the operating temperature does not exceed 180°C. In addition, since the plates are completely sealed by sealing rubber pads, there is also a compatibility problem between the fluid and the sealing rubber pads. It cannot be used in corrosive media, which limits the scope of use of the detachable plate heat exchanger; while the traditional shell-and-tube heat exchanger has disadvantages such as low heat transfer efficiency, inconvenient disassembly and cleaning; the fully welded pl...
