After searching, the Chinese patent authorization number CN219623416U discloses a spiral thick-walled seamless internal thread refrigeration copper tube. Although through holes are opened at both ends of the inner wall of the copper tube body, the through groove is connected with the inside of the copper tube body through the through holes. When the refrigerant of the utility model flows in the copper tube body, it can flow into the inside of the through groove through the through holes. The vertical lines can increase the surface area of ​​the inner wall of the through groove, thereby greatly improving the contact area between the refrigerant and the copper tube body. The purpose of quickly cooling the internal threaded copper tube can be achieved without increasing the depth of the internal thread. However, the copper tube can only increase the contact area between the refrigerant and the copper tube body, while the surface area of ​​the outer wall of the copper tube remains unchanged, which can only improve the heat exchange efficiency between the refrigerant and the copper tube body. In fact, the surface area of ​​the copper tube body for heat exchange with the external air does not change much, so the lifting effect of the refrigeration copper tube does not change much.
