The heat transfer element is a heat exchanger composed of spiral plates.

Spiral plate heat exchanger is an efficient heat exchange equipment, which is suitable for steam-steam, steam-liquid and liquid-liquid heat transfer. Suitable for chemical industry, petroleum, solvent, medicine, food, light industry, textile, metallurgy, steel rolling, coking and other industries. According to the structural form, it can be divided into non-detachable spiral plate heat exchangers (type ⅰ) and detachable spiral plate heat exchangers (types ⅱ and ⅲ).

The current standard is JB/T475 1-2003 Spiral Plate Heat Exchanger.
