Abstract:
In a computer system having a computer enclosure and a circuit board disposed therein, a heat transfer system comprising:a heat absorption chamber comprising an outer chamber having an inlet and an outlet to circulate a heat transfer liquid, the outer chamber including a top plate having the inlet formed therein and a bottom plate thermally coupled to an integrated circuit chip on the circuit board; andan inner chamber formed within the outer chamber, the inner chamber including a perforated plate disposed between the top and the bottom plates of the outer chamber and substantially perpendicular to the flow of the heat transfer liquid from the inlet such that the heat transfer liquid flows from the inner chamber to the outer chamber:a pump connected to the outlet, the pump to pump heated heat transfer liquid out of the heat absorption chamber;a heat exchanger comprising a floor of the computer enclosure and an upper surface of said floor supporting the circuit board, the heat exchanger further comprising a plurality of cooling fins substantially perpendicular to the floor and supported on the circuit board, the heat exchanger connected to the pump and to the inlet, the heat exchanger to receive and cool the heated heat transfer liquid resulting in cooled heat transfer liquid, the cooled heat transfer liquid being transferred to the heat absorption chamber via the inlet, the heat exchanger further comprising a plurality of channels formed in the upper surface that allow circulation of the heat transfer liquid from the pump to the inlet of the heat absorption chamber; anda fan to create air flow between the plurality of cooling fins.
