Problems solved by technology

[0005] The purpose of the present invention is to provide a herringbone corrugated plate for welded plate heat exchangers to solve the problems of uneven distribution of fluid in the original plate and difficult design of medium inlet and outlet structures. It is difficult to design the inlet and outlet structure of the beam medium, and at the same time eliminate the flow dead zone and improve the heat transfer efficiency

Abstract

The invention discloses a herringbone corrugated plate structure for a welding plate type heat exchanger, which comprises distributing diversion areas and a heat transfer area, wherein the triangle distributing diversion areas are arranged at the upper end and the lower end of a plate, and the rectangular heat transfer area is arranged in the middle; when the plates are assembled, supporting pieces are not needed to be additionally arranged between the plates, and the hypotenuses of the triangle distribution areas far away from the rectangular heat transfer area are connected with each other by a welding method after the plates are assembled; and the two sides of the plate are respectively used as runners of different media, and the flow directions of the media at the two sides of the plate are opposite. The invention has simple structure, even fluid distribution and no dead zone.

Description

technical field [0001] The invention relates to a herringbone corrugated plate structure for a welded plate heat exchanger. Background technique [0002] Welded plate heat exchanger is an advanced heat exchanger structure in the world at present. It uses plate heat exchange elements and welded sealing to replace the rubber gasket seal of ordinary plate heat exchangers, which greatly improves the efficiency of plate heat exchangers. Use temperature and pressure capacity. [0003] In the plate-shell feed heat exchanger, the plate is the core, and the structure of the plate directly affects the structure and heat transfer efficiency of the plate bundle. . [0004] In the existing welded plate heat exchanger, there are two types of plate structures: circular and rectangular. The circular plate and rectangular plate are complex in the design of the plate bundle structure, especially in the design of the material inlet and outlet, which is easy to cause flow dead area, which af...
