Multi-cold water pipe and multichannel heat absorption open-type communicating heat exchanger and manufacturing process thereof

Abstract

The invention discloses a multi-cold water pipe and multichannel heat absorption open-type communicating heat exchanger and a manufacturing process thereof and is used for changing cold water into hot water to take a bath in families. Porous inner plates are respectively and fixedly welded in both ends of more than two heat supply pipes; end sealing plates are fixedly welded outside both ends of each heat supply pipe; cold water heat collection distribution chambers are formed by the porous inner plates and the end sealing plates; each two heat supply pipes are welded to be communicated through a heat supply pipe communicating straight pipe; more than two cold water pipes are interpenetrated into each heat supply pipe; both ends of each cold water pipe and the porous inner plates are welded to be communicated in the manner of opening; a cold water communicating pipe penetrates through the heat supply pipe communicating straight pipe, and both ends of the cold water communicating pipe and the porous inner plates in the adjacent two heat supply pipes are welded to be communicated; a cold water inlet / outlet and the cold water heat collection distribution chambers of side pipes at both sides of the heat supply pipes are welded to be communicated; and a warm air inlet / outlet and the side pipes at both sides of the heat supply pipes are welded to be communicated. According to the multi-cold water pipe and multichannel heat absorption open-type communicating heat exchanger disclosed by the invention, the heat absorption area is increased by fully utilizing an effective heat source through multi-dividing wall heat absorption and stepped heat transfer, therefore, the heat absorption is rapid, and the heat exchange efficiency that the temperature is changed in the manner of gradient is high.
