[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements, and it is an industrial application of convective heat transfer and heat conduction. The household heat exchanger solves the problems of collective heating households and using hot water in winter. Its working principle is the same as that of the heat exchanger for collective heating, only the size and style are different.

[0003] Among them, the publication (announcement) number: CN210154087U discloses a composite condensing heat exchanger, which includes a heat exchanger housing. A water pipe is fixedly connected inside the heat exchanger housing for the input and output of cold water. An anti-corrosion coating is applied to the outer end of the water pipe to protect the water pipe from being corroded by acidic liquids. An output pipe is fixedly connected to the upper end of the heat exchanger housing for outputting the cooled flue gas. Please refer to the figure. An input pipe is fixedly connected to the side end of the heat exchanger housing for inputting the flue gas at high temperature. The water pipe is located between the input pipe and the output pipe. A water outlet pipe is fixedly connected to the bottom end of the heat exchanger housing for outputting condensed water.

The condensing pipe 2 is a serpentine pipe, and two fixed pipe clamps 11 are symmetrically arranged on the pipe wall of the condensing pipe 2. The fixed pipe clamps 11 can increase the overall structural strength of the condensing pipe 2. The upper and lower ends of the condensing pipe 2 are respectively rotatably connected to the top and bottom of the housing 1. A water supply tank 3 is fixedly arranged at the top of the housing 1, and a communicating water tank 4 is fixedly arranged at the top of the housing 1. The output end of the water supply tank 3 is connected to the communicating water tank 4. The upper end of the condensing pipe 2 is connected to the communicating water tank 4. The upper end of the condensing pipe 2 extends into the interior of the communicating water tank 4, and a water inlet hole 12 is formed in the pipe wall of the condensing pipe 2. The condensing pipe 2 is rotatably connected to the housing 1 and the communicating water tank 4 through sealed bearings, which can improve the rotational sealing performance of the condensing pipe 2 and avoid leakage. The condensed water inside the water supply tank 3 can be discharged into the communicating water tank 4 and then enter the interior of the condensing pipe 2 through the water inlet hole 12, so that the pipe wall of the condensing pipe 2 is cooled; a fixed frame 5 is fixedly arranged at the top of the communicating water tank 4, a motor 6 is fixedly arranged inside the fixed frame 5, the output end of the motor 6 is fixedly connected to the upper end of the condensing pipe 2, a return water tank 7 is fixedly arranged at the bottom of the housing 1, a bottom frame 14 is fixedly arranged at the bottom of the housing 1, and the return water tank 7 is fixedly arranged inside the bottom frame 14. The lower end of the condensing pipe 2 is rotatably connected to the input end of the return water tank 7. A rotary joint 13 is fixedly arranged at the input end of the return water tank 7. The lower end of the condensing pipe 2 is rotatably connected to the input end of the return water tank 7 through the rotary joint 13. A water inlet pipe 8 is fixedly arranged at the top of one side of the housing 1, and a water outlet pipe 10 is fixedly arranged at the bottom of the other side of the housing 1. The hot fluid enters the interior of the housing 1 through the water inlet pipe 8, so that the hot fluid contacts the pipe wall of the condensing pipe 2 and conducts heat exchange. After the hot fluid is cooled, it is discharged outward through the water outlet pipe 19. When the motor 6 works, it can drive the condensing pipe 2 to rotate, so that the condensing pipe 2 rotates inside the housing 1 and stirs the hot fluid, accelerating the flow rate of the hot fluid and improving the contact effect between the hot fluid and the pipe wall of the condensing pipe 2, thereby improving the efficiency of heat exchange.

[0030] Embodiment 2

[0031] Referring to Figure 1 and 3, stirring plates 15 are vertically and fixedly arranged on both sides of the condenser tube 2. A plurality of uniformly distributed stirring holes are formed on the side surface of the stirring plate 15. The housing 1 is in a cylindrical shape, and a plurality of uniformly distributed flow disturbing blocks 16 are fixedly arranged on the inner side wall of the housing 1.
