Description

Technical Field

[0001] The utility model relates to the field of heat exchange equipment, in particular to a heat exchanger. Background Art

[0002] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed by heat conduction, heat convection and heat radiation. Heat exchange is also called heat exchange, which is the process of heat energy being transferred from hot fluid to cold fluid indirectly or directly. It is complex in nature and not only heat conduction through the partition wall must be considered, but also convection heat transfer of the fluids on both sides of the partition wall, and sometimes radiation heat transfer must also be considered.

The heat exchanger, through the arrangement of the mounting assembly and the heat exchange assembly, starts the water pump to input cold water from the water pipe into the heat exchange assembly, connects the pipe for outputting hot air to the air inlet pipe, turns on the air pump to extract the gas in the mounting seat, and the hot air enters the mounting seat to heat the water source in the heat exchange pipe. After the heating is completed, the air pump is started again to input and extract the cold air and input the hot air, and the regulating valve is opened to allow the heated water to enter the water storage tank to complete the heat exchange operation, so that the device can absorb and utilize the heat in the discharged hot air to avoid direct discharge and pollution to the air, and the device has low cost and high versatility.
