The specific type of spiral heat exchanger
Apr 25, 2021

Spiral plate heat exchangers are generally divided into two types: detachable and non-detachable. Among them, the non-detachable structure is relatively simple, that is, all ends of the spiral channel are welded to death, so that it is not removable. The detachable spiral plate heat exchanger is different in structure from the non-detachable type, mainly in that the two ends of the spiral channel are sealed structures instead of welded dead. As for the other parts, it is exactly the same. For sealing, it is generally sealed with a flat cover and gasket. In addition, in order to improve the pressure-bearing capacity of the spiral plates, spacers are also used between the plates to support.
