the water inlet pipe and the water outlet pipe are respectively connected with two ends of the heat exchange pipes, and the water inlet pipe and the water outlet pipe are communicated through the plurality of heat exchange pipes.
Further, the heat exchange tube is elliptical.
Further, the number of the heat exchange tubes is nine, and the nine heat exchange tubes are arranged in parallel between the two support plates.
Further, the bayonet in the fin is in a shape matched with the heat exchange tube.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
according to the stainless steel heat exchanger, the heat exchange tubes adopt the elliptical shape, so that the heat exchange area is effectively increased, the effective space can be provided with a plurality of rows of heat exchange tubes, the heat exchange area is increased, and the heat energy conversion rate is improved; meanwhile, the bottom of the flanging of the fin is provided with the guide groove, and the welding liquid or soldering paste is guided into the gap between the fin and the heat exchange tube through the guide groove, so that the use of raw materials is reduced, and meanwhile, the connection is firm.
