Gas-plate heat exchanger is a group of modular heat exchange components made of plates with special structure by welding, and then assembled into integrated heat exchange equipment in line with the actual operating conditions of users after pressure testing and other links. It has the characteristics of high heat exchange efficiency, compact equipment, light weight, small area and low resistance, and the heat exchange area per cubic meter can reach 50-80 square meters. Suitable heat exchanger is the product of the combination of practice and theory for many years, its heat transfer film coefficient is high, is 1.5 times of ordinary tube, finned tube more than 2 times, at the same time does not have the characteristics of heat pipe heat exchanger attenuation, its life can be guaranteed. Following the pace of industrial modularization, suitable heat plate heat exchanger also adopts the modular design, the maximum area of a single assembly can reach 10000m2.
