Patent attributes
A radiator of a display card includes a heat absorbing set, a main cooling set, and a pump assembly. The heat absorbing set has a heat absorbing base disposed on the display card and a heat exchanging tank disposed on the heat absorbing base. The main cooling set mainly includes two opposite containers disposed at two ends of a frame unit and filled with a cooling material, heat dissipating pipes communicating with the containers and inserting into the heat exchanging tank, and radiating fins disposed between the heat dissipating pipes to contribute to heat dissipation. The cooling material circulates between the containers and passes the heat exchanging tank via the heat dissipating pipes to dissipate heat and reduce the temperature of the display card effectively. The radiator is assembled with a compact structure whereby a small volume is provided to facilitate the development of computer miniaturization.
