Abstract

Abstract A cooling system for cooling at least one semiconductor component, including a convection heat exchanger thermally coupled to the component and a refrigeration cycle thermally coupled to the heat exchanger and including a compressor, a condenser, a collector, an expansion valve and an evaporator. The evaporator is coupled in series with the heat exchanger to form a coolant cycle for recooling of the coolant. At least one fan is provided for forcibly ventilating the convection heat exchanger. The condenser of the refrigeration cycle is installed in the heat exchanger whereby the fan serves also to cool the condenser. A coolant, in particular trifluortrichlorethane (C 2 F 3 Cl 3 ), having a boiling point below the wall temperature of the semiconductor component being cooled is used.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 145 words
A cooling system for cooling at least one semiconductor component, comprising: a coolant flow circuit connected with said component a convection heat exchanger connected in said circuit; a refrigeration cycle system thermally coupled to said coolant circuit and including a compressor, a condenser, a collector, an expansion valve, and an evaporator, said evaporator coupled in series with said exchanger in said circuit; at least one fan for forcibly ventilating said convection heat exchanger for thereby cooling the at least one semiconductor component; said condenser of said refrigeration cycle system installed in said forcibly ventilated convection heat exchanger whereby said at least one fan serves also to cool said condenser; and a coolant suitable for combined convection and boiling cooling being used in the coolant circiut, said coolant having a boiling point below the wall temperature of said at least one semiconductor component to be cooled.
