Examples

As shown in fig. 1 to 6, the efficient fin 20 type heat exchanger of the present embodiment includes a plurality of fins 20 parallel to each other, a plurality of main tubes 10 inserted into the fins 20, a conduit 11 disposed at an end of the main tubes 10, a first heat pipe 12 disposed inside the main tubes 10, a plurality of second heat pipes 13 inserted into the fins 20, a connecting pipe 14, and a circulation device; the plurality of main pipes 10 and the plurality of second heat-conducting pipes 13 are arranged alternately in sequence; the two ends of the first heat pipe 12 are closed ends, and the end of the first heat pipe 12 is connected to the end of the adjacent second heat pipe 13 through a connecting pipe 14; the first heat conduction pipe 12 and the second heat conduction pipe 13 are sequentially connected in an end-to-end manner to form a single channel; the circulation device is in conductive connection with both the first heat transfer pipe 12 and the second heat transfer pipe 13 at the end portions. Specifically, when in use, the conduits 11 at the two ends of the main pipe 10 are connected to an external water supply pipeline (wherein the main pipe 10 may also be connected in a terminating manner, so that a plurality of main pipes 10 form a single or multiple pipelines), so that the heat medium can enter the inside of the main pipe 10 and exchange heat through the fins 20, in the process, the heat medium inside the main pipe 10 can also heat the heat medium inside the first heat conduction pipe 12 and make the heat medium in the first heat conduction pipe 12 and the heat medium in the second heat conduction pipe 13 circularly flow under the action of the circulating device, so that the heated heat medium inside the first heat conduction pipe 12 enters the second heat conduction pipe 13 through the connecting pipe 14, the second heat conduction pipe 13 is connected to the fins 20 and can further exchange heat with the outside, the cooled heat medium inside the second heat conduction pipe 13 enters the next first heat conduction pipe 12 through the connecting pipe 14 and is heated again, this cycle repeats the process, so that heat exchange can be performed by sufficiently using the heat of the heat medium in the main pipe 10, the heat exchange efficiency is remarkably improved, and the efficiency of heating or heat radiation is improved.

In this embodiment, the outer wall of the first heat pipe 12 is uniformly provided with a plurality of connecting blocks 15, and the connecting blocks 15 are fixedly connected with the inner wall of the main pipe 10. Specifically, the connecting blocks 15 are not only used for connecting the first heat pipe 12 and the main pipe 10, but also can ensure a certain gap between the first heat pipe 12 and the main pipe 10, wherein for the convenience of installation, it is sufficient to weld the connecting blocks 15 at two ends of the first heat pipe 12 and the inner wall of the main pipe 10.
