HEAT EXCHANGER Russian patent published in 1996 - IPC

FIELD: air-conditioning systems of transport facilities. SUBSTANCE: heat exchanger is made in form of coil from flat multi-pass tube 1 provided with external fins due to which hydraulic losses in passages of heat exchanger are considerably reduced. Tube 1 is provided with inlet and outlet manifolds which are divided by partition 5 which closes passage area of tube 1. Tube 1 is also provided with additional outlet manifolds 6 and inlet manifolds 7 connected before and after partition 5 in way of flow of working medium. Length of route of working medium flow from inlet to outlet of heat exchanger is reduced due to availability of partition 5 and additional inlet manifold 7 and outlet manifold, thus reducing hydraulic losses in heat exchanger passages and enhancing efficiency of heat exchange. EFFECT: reduction of hydraulic losses and enhanced efficiency of heat exchange. 2 dwg
