▎ 摘  要

NOVELTY - The utility model relates to the technical field of heat exchanger, and claims a shell-and-tube heat exchanger, comprising a heat exchanger main pipe. The utility model through the first graphene heat exchange tube is sleeved with a second graphene heat exchange tube, using graphene good thermal conductivity to improve the heat exchange effect, the middle end position of the first graphene heat exchange tube and the second graphene heat exchange tube are set as a spiral structure, in the limited space, enlarging the heat exchange contact area, enhances the heat exchange effect, the spiral structure of the first graphene heat exchange pipe and the second graphene heat exchange pipe is located in the cooling heat exchange cavity, and the heat exchanger main pipe is equipped with a motor rotating device, the motor rotating device and the heat exchange mechanism are matched with each other, so that the first graphene heat exchange tube and the second graphene heat exchange tube are rotated in the cooling liquid of the cooling heat exchange cavity, further improving the heat exchange effect and heat exchange efficiency.
