Spiral wound tube heat exchanger, also known as threaded tube wound heat exchanger or spiral threaded tube heat exchanger, is a representative work of the new heat exchange products. Mainly applicable to vapor-liquid heat exchange conditions, it is designed based on CFD computational fluid dynamics technology, FEM differential finite element technology, 0WEN turbulent oscillation frequency criterion, Eisinger criterion, Bevinsbbb criterion, asymmetric flow design and other techniques. At present, the highest heat transfer coefficient under steam water heat exchange conditions can reach 14000w/m ºC. According to the flow rate, flow channel, or other requirements of the enterprise itself, the specifications of ¢ 8, ¢ 10, ¢ 12, and ¢ 19 wrapped pipes can be selected to meet the production requirements of the enterprise. The steam water heat exchange unit consists of a heat exchanger, a circulating pump unit, a constant pressure pump unit, sensing instruments, control valves, and an automatic control device (frequency conversion cabinet). It is a fully automatic unmanned heat exchange equipment developed by Tengrui Energy saving. Its main components - the coil heat exchanger, controller, frequency converter, etc. - are all international brands, with excellent options, compact structure, high heat exchange efficiency, stable system operation, and convenient construction. It is currently the most ideal heat exchange equipment. Reasonable combination of multiple systems, integrating heat exchange system and constant pressure system, without the need for additional high-level water tanks or other constant pressure devices, compact structure, small footprint, and easy maintenance for fully automatic operation.
