[0002] A heat exchanger is a heat exchange device used to transfer heat between two fluids. Its main purpose is to achieve energy transfer, so that the temperature of one fluid increases and the temperature of the other fluid decreases. This is very important in many industrial processes and applications in life. The parallel flow heat exchanger is mainly composed of multiple perforated tubes and louver-like fins. There are headers at both ends. Depending on whether the headers are segmented or not, it can be divided into multi-parallel flow type and unit parallel flow type.

[0031] Specifically, the steel tube 17 and the steel tube 2 19 are small-diameter heat exchange tubes. Multiple steel tubes 19 and the second aluminum fins 20 form the first core.

Through the upper water chamber upper cavity structure, the first process of the core is realized. By connecting multiple steel tubes 17 and the first aluminum fins 20 to form the second core, the upper side brackets 14 are placed at both ends, and are respectively connected to the upper and lower water chamber supports by welding (or expansion joint).

When the steam passes through the steel pipe 17, the fan inhales the external air and blows it over the surface of the first aluminum fin 8 and the second aluminum fin 20, and the heat is liquefied into liquid through the first aluminum fin 8 on the outer wall of the steel pipe 7. Then, the liquid and some incompletely liquefied steam enter the cavity composed of the upper water chamber support 16, the upper water chamber main board 17 and the upper water chamber sealing plate 18 through the water pipe 13. The silicone tube 13 connects the two heat exchangers through the connecting pipe 12 and the connecting pipe 2 15. After further cooling and liquefaction through the steel pipe 2 19, it flows into the cavity composed of the upper water chamber sealing plate 23, the upper water chamber main board 22 and the upper water chamber support 21, and is finally discharged through the liquid outlet pipe 24.
