Brazed heat exchanger does not have sealant pad, all the plates are made of high temperature melted and welded copper foil, plate has a unique herringbone corrugated design, can make the fluid in low flow rate also achieve the effect of turbulence, heat transfer efficiency is high, its volume is usually small, mainly used in high temperature and high pressure, rubber pad can not adapt to the working conditions. It also has certain disadvantages, brazing heat exchanger can not be separated to clean, can not be repaired, the price is slightly higher.

Brazed plate heat exchanger is one of the new equipment in the field of heating and cooling. It has the advantages of compact structure, small footprint, high heat transfer efficiency, convenient operation and maintenance, and the ability to deal with small temperature difference. As a high efficiency and energy saving product, it has been widely used in mining, metallurgy, petroleum, chemical industry, machinery, electric power, medicine, food, textile, paper, shipping, Marine development and other industrial fields.
