Heat-transfer heat exchanger with double-channel heat supply pipes and production process of heat-transfer heat exchanger with double-channel heat supply pipes

Abstract

The invention relates to a heat-transfer heat exchanger with double-channel heat supply pipes and a production process of the heat-transfer heat exchanger with the double-channel heat supply pipes. The heat-transfer heat exchanger comprises two or more outer heat supply pipes. An outer heat supply pipe seal is fixedly connected to the end of each outer heat supply pipe, a tap water heat absorption pipe is arranged in each outer heat supply pipe, the heat supply pipes are communicated with one another through heat supply pipe communication pipes, and the tap water heat absorption pipe are communicated with one another through water tap communication pipes. A hot air inlet and a hot air outlet are fixedly communicated with an inlet end and an outlet end of the outer heat supply pipes respectively, a tap water inlet and a tap water outlet are fixedly communicated with an inlet end and an outlet end of the tap water heat absorption pipes respectively, part or all of tap water heat absorption pipes are provided with inner heat supply pipes which are communicated with cavities of the outer heat supply pipes. By means of double-channel reverse-flow type convective heat transfer with the inner and outer heat supply pipes, heat transfer area is widened, heat transfer efficiency is improved, and hot water at a temperature higher than 38 DEG C can be outputted continuously for a long time without stopping. The heat-transfer heat exchanger with the double-channel heat supply pipes belongs to updated products.
