Double-layer five-pipe double-pipe exchanger for gas water heating furnace heating

Abstract

The invention discloses a double-layer five-pipe double-pipe exchanger for gas water heating furnace heating. The double-layer five-pipe double-pipe exchanger comprises a heat exchanger body, and is provided with five water passing pipelines which are longitudinally double-layer parallel and are arranged in a staggered mode, and the five water passing pipelines are used for providing heating waterand bathing water; a plurality of heat collecting sheets are arranged on the outer sides of the water passing pipelines, the water passing pipelines matches with round tubular inner sleeves to form adouble water passing pipeline which is internally provided with an upper heating water channel, a lower heating water channel and a middle bathing water channel which are independent from one another; the two ends of the five water passing pipelines are correspondingly connected with a heating water inlet water box and a heating water outlet water box, the heating water inlet water box is connected with a heating water inlet connector, and the heating water outlet water box is connected with a heating water outlet connector; and a bathing water inlet connecting bend is arranged at pipe orifices of the two adjacent water passing pipelines, and meanwhile, opposite end ports of the two water passing pipelines at the outermost side are correspondingly provided with a bathing water inlet connector and a bathing water outlet connector. According to the double-layer five-pipe double-pipe exchanger, the use amount of sheet metal of a whole machine product can be effectively reduced, the production material and the transportation cost are reduced, and the excellent heating effect of rapid heating speed and excellent heat exchange is achieved.

Description

technical field [0001] The invention relates to the technical field of gas-fired heating water heaters, in particular to a double-layer five-pipe casing heat exchanger for heating with a gas-fired water heater. Background technique [0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. The water pipes of traditional heat exchangers are directly arranged in series, and the ports of adjacent water pipes are connected by connecting pipes, while the ports that are not connected to each other are connected with water inlet and outlet pipes, cold water directly enters the water pipes, and the water pipes are directly installed There are heat collectors, and the heat exchanger is heated by the cold water in the tubes through the heat collectors, but this kind of heat exchanger needs to use a lot of metal materials, and th...
