Abstract:
A heat dissipating apparatus for dissipating heat released from a heat-generating side of an integrated circuit device that is mounted on a circuit board, said heat-dissipating apparatus comprising:a base member having an upright surrounding wall portion that confines a receiving space with an area larger than the integrated circuit device, and a top wall that is formed on a top end of said surrounding wall portion so as to close a top side of said receiving space, said base member being adapted to be disposed on the circuit board such that the integrated circuit device is accommodated within said receiving space, said top wall having an upper wall surface and a lower wall surface opposite to said upper wall surface and formed with a serpentine fluid groove that opens downwardly and that has opposing first and second groove ends, said top wall further having a fluid inlet in fluid communication with said first groove end, and a fluid outlet in fluid communication with said second groove end;a thermoelectric cooling unit disposed in said receiving space below said top wall and having a heat-absorbing side adapted to be placed in contact with the heat-generating side of the integrated circuit device, and a heat-releasing side opposite to the heat-absorbing side, said cooling unit having a size corresponding to the area of the receiving space and being adapted to separate the integrated circuit device from said fluid groove; anda washer member disposed in said receiving space below said cooling unit, said washer member having an inner peripheral portion formed with a through hole that is adapted to contain the integrated circuit device therein, an outer peripheral portion that establishes a fluid-tight seal with said surrounding wall portion of said base member, a top surface that establishes a fluid-tight seal with said heat-absorbing side of said cooling unit, and a bottom surface that is adapted to establish a fluid-tight seal with the circuit board.
