Abstract
Abstract An apparatus (10) for cooling a vehicle air conditioning system electrical controller (20) includes a chill block (10) in juxtaposition to the controller (20). The chill block (10) includes a channel (22) that forms a cooling groove in heat exchange relation with the controller (20). The chill block (10) receives a portion of the refrigerant being circulated in the system (12). The portion of the refrigerant received expands in the chill block (10) to a saturated vapor and extracts heat from the controller (20) as the heat of vaporization from such expansion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
A cooling apparatus in combination with an electrically driven automotive air conditioning system including an electrical component and a liquid refrigerant for the system, the cooling apparatus comprising: a member having a channel having an inlet and outlet therein mounted on a surface of the component; the inlet of said channel being in communication with the refrigerant for receiving and communicating the refrigerant to the outlet; said member expanding the liquid refrigerant between the inlet and outlet to a saturated vapor which is thereby communicated in heat exchange relation with the electrical component, to cool the component; and a seal of an aluminum plate for effecting a seal between said member and component so that the component can be disconnected from the cooling apparatus without leaking refrigerant.
Claim 2
Dependent Claim
127 words
A cooling apparatus in combination with an electrically driven automotive air conditioning system including an electrical component and a liquid refrigerant for the system, the cooling apparatus comprising: a member having a channel having an inlet and outlet therein mounted on a surface of the component; the inlet of said channel being in communication with the refrigerant for receiving and communicating the refrigerant to the outlet; said member expanding the liquid refrigerant between the inlet and outlet to a saturated vapor which is thereby communicated in heat exchange relation with the electrical component, to cool the component; and a seal of an aluminum plate for effecting a seal between said member and component so that the component can be disconnected from the cooling apparatus without leaking refrigerant.
Claim 3
Dependent Claim
20 words
The combination of claim 1 wherein said seal means further includes an O-ring mounted between said aluminum plate and member.
Claim 4
Dependent Claim
103 words
Apparatus for cooling the electrical controller of an air conditioning system having a condenser, evaporator, expansion device and a compressor for circulating refrigerant to the evaporator and from the condenser, and comprising: a chill block that comprises a non-heat conductive plastic material in juxtaposition to said controller and forming therewith a cooling groove in heat exchange relation with said controller and receiving at least a portion of the refrigerant being circulated to the evaporator, said portion received into said groove expanding in the chill block to a saturated vapor and extracting heat from said controller as the heat of vaporization from such expansion.
Claim 5
Dependent Claim
103 words
Apparatus for cooling the electrical controller of an air conditioning system having a condenser, evaporator, expansion device and a compressor for circulating refrigerant to the evaporator and from the condenser, and comprising: a chill block that comprises a non-heat conductive plastic material in juxtaposition to said controller and forming therewith a cooling groove in heat exchange relation with said controller and receiving at least a portion of the refrigerant being circulated to the evaporator, said portion received into said groove expanding in the chill block to a saturated vapor and extracting heat from said controller as the heat of vaporization from such expansion.
Claim 6
Dependent Claim
13 words
Apparatus as in claim 3 wherein said sealing means is an aluminum plate.
Claim 7
Dependent Claim
21 words
Apparatus as in claim 4 wherein said sealing means further includes an O-ring mounted between said aluminum plate and chill block.
