At the same time, each graphite modified heat exchanger body 80 is connected end to end in sequence through the connecting pipe 70, which can ensure the smooth flow of the fluid and reduce the flow resistance. By installing a plurality of groups of graphite modified heat exchange straight pipes 10 evenly and equidistantly arranged between the inlet cover 20 and the outlet cover 30, the heat exchange area can be further expanded and the heat exchange efficiency can be improved. At the same time, due to the special material and structure of the graphite modified heat exchange straight pipe 10, the heat exchange effect can be enhanced and the performance of the heat exchanger can be improved. By installing flanges 41 at the ends of the inlet pipe 50, the outlet pipe 40 and the connecting pipe 70, and opening a plurality of evenly and equidistantly arranged connecting holes 42, other pipelines or equipment can be easily connected to realize the expansion and integration of the entire heat exchange system.

[0035] It is worth noting that the number of the graphite modified heat exchanger bodies 80 on the fixed chassis 60 is at least 2 groups, which can increase the heat exchange area of ​​the heat exchanger and improve the heat exchange efficiency.

[0036] Furthermore, the thickness of the graphite modified heat exchange straight tube 10 is 1-3 mm, which can ensure the strength and rigidity of the heat exchange straight tube, while reducing the overall weight, saving materials and costs.
