Heat exchanger

By controlling the relationship between the thickness of the heat exchanger plates and the height of the protrusions, designing point-like maximum thinning areas and fixing the top and sides of the protrusions, the problem of insufficient strength and corrosion resistance in the processing of thin plates is solved, achieving high strength and corrosion resistance for even thinner plates.

AI Technical Summary

Technical Problem

In existing heat exchangers, the high material thinning rate when processing grooves or protrusions in thin plates leads to insufficient strength and corrosion resistance.

Method used

By employing a first and second plate design, the relationship between the plate thickness and the protrusion height is controlled, ensuring that the thickness of the top of the protrusion is less than the thickness of the side. By fixing the top and side of the protrusion, the thickness of the weak area is increased, forming a point-like maximum thinning area, ensuring that the side of the protrusion has sufficient thickness, thereby improving strength and corrosion resistance.

Benefits of technology

It effectively reduces the range of the maximum thinning area of ​​the plate, improves the strength and corrosion resistance of the heat exchanger, and is suitable for thinner plates to reduce weight and cost.
