The curved path 701 and the tube pass 7 are an integrated connection structure, and the spiral plate 703 and the groove 702 are evenly arranged on the surface of the curved path 701. Through the arrangement of the curved path 701, the straight tube pass 7 is transformed into a pipeline with a curved structure, which can slow down the flow speed of the fluid inside the tube pass 7 and improve the heat exchange effect between the fluids.

Through the provision of the tube hole 801, the tube pass 7 can be positioned and installed.

Through the setting of the bracket 9, the heat exchanger body 1 is supported from the bottom of the heat exchanger body 1. The support 903 at the bottom of the bracket 9 is installed in an eight-shaped shape at the bottom of the bracket 9, which can increase the stability of the heat exchanger body 1. At the same time, a heat dissipation fan 901 is installed on the surface of the bracket 9, which can assist in heat dissipation of the bottom surface of the shell of the heat exchanger body 1.
[0023] Working principle: For this type of heat dissipation shell and tube heat exchanger, first, the cold fluid will enter the interior of the heat exchanger body 1 from the cold fluid inlet 3 at the right end of the heat exchanger body 1. Due to the setting of the tube box plate 6, the internal middle of the heat exchanger body 1 is blocked, so the cold fluid will flow into the interior of the tube pass 7. At the same time, the hot fluid enters the internal middle of the heat exchanger body 1 from the hot fluid inlet 4 above the heat exchanger body 1. The tube box plate 6 seals and isolates the middle space of the heat exchanger body 1. Therefore, the hot fluid will flow outside the tube pass 7. The setting of the curved channel 701 transforms the straight tube pass 7 into a pipe with a curved structure, which allows the fluid to flow in the tube pass 7. The flow speed is slowed down, so that the hot fluid on the outside can better exchange heat with the fluid inside the tube 7. During the flow process, the setting of the baffle 8 will change the flow direction of the fluid and allow the fluid to contact the tube 7 more. When the fluid contacts the baffle 8, the flow strip 802 increases the resistance amount and slows down the flow speed of the fluid. The fluid enters from the hot fluid inlet 4 and flows from left to right. After exchanging heat with the tube 7, it is discharged from the hot fluid outlet 5. Secondly, the heat on the shell surface of the heat exchanger body 1 will be dissipated by the heat sink 101, thus completing the use process of the entire heat dissipation shell and tube heat exchanger.
