Heat exchanger pipe for use in heat exchanger of air conditioning system, has lamellas with bent section including bent areas separated from each other by recesses, where adjacent areas of bent section are bent in opposite directions

摘要

The pipe (1) has lamellas (5) winding screw-shaped around a fluid pipe (3) and exhibiting a bend section at ends of the lamellas, where the ends turned to the fluid pipe and the lamellas are connected adhesively with the fluid pipe in the bend section. The bent section includes bent areas separated from each other by recesses, where the adjacent areas of the bent section are bent in opposite directions. External radius of the lamellas lies in a range between double and quadruple radius of the fluid pipe. An independent claim is also included for an air conditioning system, comprising a heat exchanger.
