AI Technical Summary

Technical Problem

In existing plate heat exchangers, the rubber gaskets are not accurately positioned when the plates are bonded together, resulting in uneven stress, which may lead to leakage. In addition, the heat exchange surface area is small, affecting the heat exchange efficiency.

Method used

The heat exchange plate is designed with multiple raised strips and guide grooves. The raised strips are spaced apart with grooves. The bottom surface of the grooves is inclined. The guide grooves are tilted. Combined with the positioning protrusions and positioning holes, the rubber gasket is laid flat and the sealing performance is improved.

Benefits of technology

By increasing the heat exchange area and guiding the flow, the heat exchange efficiency is improved, and the sealing performance is enhanced to prevent leakage.

Abstract

This utility model discloses a heat exchanger with high heat exchange efficiency, comprising: a heat exchange zone on a heat exchange plate, multiple raised strips and guide grooves spaced apart on the heat exchange zone, multiple spaced grooves on the raised strips, the bottom surface of the grooves being inclined, and the bottom surfaces of adjacent grooves having opposite inclination directions; positioning protrusions on both sides of the heat exchange zone; positioning grooves on the periphery of the heat exchange plate, and positioning holes in the positioning grooves. The heat exchange zone of this utility model features symmetrical guide grooves, and the grooves spaced apart on the raised strips, with inclined bottom surfaces, expand the heat exchange area. The inclined bottom surfaces act as guides, and the positioning protrusions and positioning holes on the plate facilitate the fixing of rubber gaskets, ensuring a smooth fit and improving sealing performance.
