HEAT EXCHANGE TUBE, HEAT EXCHANGER AND HEAT PUMP SYSTEM Russian patent published in 2021 - IPC F28F1/42 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat engineering and can be used for the heat exchange tube of heat exchangers and in heat pumping units. The heat exchange tube contains a pipe body and an edge located on the outer surface of the pipe body, while the rib contains a tail part located on the outer surface of the pipe body, a transverse part of the rib located on the upper side of the tail part of the rib extending laterally from the two sides of the tail part of the rib, and the upper part of the rib located on the upper part of the transverse part of the rib, made in the form of a sawtooth part, while the concave part of the specified sawtooth part passes to the transverse part of the rib.

EFFECT: increase in the heat exchange area of the upper part of the rib and the thinning of the liquid film; the specified upper sawtooth part of the rib is effective for the flow of the refrigerant, while the ability to condense increases; and the transverse part of the rib departs laterally from the two sides of the rib to form the lower tier of the channel and the upper tier of the channel, significant for evaporation and condensation, and as a result, the heat exchange tube has the ability to evaporate and condense.
