Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and more specifically, it relates to a vortex heat exchanger. Background Technology

[0002] A boiler (water heater) is a commonly used thermal energy device that converts the chemical energy of fuel into mechanical energy. It mainly consists of a combustion chamber and a heat exchanger. The heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Currently, the tube bundle of the heat exchanger is the core part of heat exchange.
