Spiral tube heat exchanger is a high-efficiency heat exchange equipment, which consists of two or more spiral shaped channels, which are usually composed of metal plates or tubes, which are wound around each other to form a spiral. In these spiral channels, one fluid flows in the inner spiral channel, while another fluid flows in the adjacent outer spiral channel. Because of the spiral shape, the fluid forms continuous turbulence during flow, which helps to improve the efficiency of heat exchange.
