1results about How to "Good heat conduction efficiency" patented technology

The application provides a heat dissipation device, an electronic module and an energy storage device. The heat dissipation device comprises a heat conduction member, the heat conduction member is integrally formed with a first heat conduction part and a second heat conduction part; the cross sections of the first heat conduction part and the second heat conduction part are circular in a direction perpendicular to a circuit board, and the diameter of the first heat conduction part is smaller than that of the second heat conduction part; the first heat conduction part is arranged in a through hole and is in heat conduction connection with an electronic device; and the second heat conduction part is fixedly connected to the circuit board. The heat conduction member is integrally formed, the heat conduction efficiency is better, the heat dissipation effect is better, the turning processing is easier, the processing mode is simpler, the production manufacturing cost is reduced, and the production benefit is improved.
