A heat dissipation structure for high-power heat sources

Abstract

This invention discloses a heat dissipation structure for a high-power heat source, including a heat dissipation base, a water-cooled heat dissipation assembly, and an auxiliary heat dissipation assembly. The heat dissipation base has a receiving groove. The water-cooled heat dissipation assembly includes a water-cooled plate, an inlet pipe, an outlet pipe, and a driving component. The water-cooled plate is housed in the receiving groove, and the side of the water-cooled plate away from the bottom wall of the receiving groove is a heat source contact area, which is used to contact the heat source to absorb the heat generated by the heat source. Both ends of the inlet pipe are connected to the driving component and the water-cooled plate, respectively. Both ends of the outlet pipe are also connected to the driving component and the water-cooled plate, respectively. The driving component drives the cooling fluid to circulate between the inlet pipe, the water-cooled plate, and the outlet pipe. The auxiliary heat dissipation assembly assists the water-cooled plate in heat dissipation. This invention solves the problems of traditional water-cooling heat dissipation having a single heat dissipation path and incomplete heat removal.
