Problems solved by technology

Traditional heat exchangers have the following disadvantages: small heat transfer area, poor heat transfer effect, suitable for use in small spaces such as homes, for places with large spaces such as factories, a large number of heat exchangers need to be installed to meet the use requirements, not only The investment is large, and more production space is occupied by the heat exchanger and the connecting pipeline; if the traditional tubular heat exchanger wants to improve the heat exchange efficiency, the most direct way is to use copper with high cost, and the thermal conductivity will be greatly improved. However, for the sake of cost performance, cheap stainless steel is still used in common occasions
