Heat pipe radiating device

The utility model relates to a heat pipe radiating device, which is connected with a heating element, and comprises a ventilator with an air inlet and an air outlet; cooling fin assembly, the radiatorcomprises a first radiating fin group and a second radiating fin group connected with the first radiating fin group in an inserted manner, the cooling fins of the first cooling fin set are arranged at intervals in the second direction, the cooling fins of the second cooling fin set are arranged at intervals in the third direction to form a cooling channel extending in the first direction, the cooling channel is communicated with an air outlet of the ventilator, and the first direction, the second direction and the third direction are arranged in an intersecting mode. The heat pipe assembly isarranged on the peripheral side of the cooling fin assembly; heat generated by the heating element is transmitted to the cooling fin assembly through the heat pipe assembly and diffused out through the ventilator. The cooling
