TUBULAR SPIRAL AND HEAT EXCHANGER WITH IMPLEMENTATION THEREOF Russian patent published in 2018 - IPC F28F1/02 F28D7/04 

FIELD: heating equipment.

SUBSTANCE: invention relates to the field of heat engineering and can be used in heat exchangers for the utilization of heat, heating and cooling liquid food products; distillation, desalination of water. Invention consists in the fact that in a heat exchange device containing at least one tubular spiral in the form of an Archimedes spiral with a gap between the turns, forming an annular space and the elements of its connection to the external main, the body and the cover with the elements of input and output of the medium of the annular space, the transverse profile of the turns of the helix has an arcuate shape with a slit-like gap between the inner walls forming the inside-tube space and the round ends, and the elements of the spiral connection with the external connection are the fittings inserted into the round ends of the spiral. In the heat exchanger, the lid is not connected to the body, but is pressed against the spiral by its own weight or weight. Heat exchanger can be installed under the shower tray.

EFFECT: simplified design of the spiral heat exchange device, increased service life and heat exchange efficiency.
