A heat exchanger for cooling oil, including a plurality of pan-shaped heat-transfer plates stacked onto one another to define alternating channels for coolant and oil, a mounting plate soldered on one side to a side of the stacked plates and adapted to mount on its opposite side to a separate component. Openings through the heat-transfer plates and the mounting plate are provided for the passage of the oil and of the coolant, where the openings in the mounting plate have recesses therearound on the side opposite the heat-transfer plates. The recesses are adapted to receive seals therein.

The invention claimed is: 1. A heat exchanger for cooling oil, comprising: a plurality of pan-shaped heat-transfer plates stacked onto one another to define alternating channels for coolant and oil; a mounting plate soldered on one side to a side of the stacked plates, said mounting plate being adapted for mounting on its opposite side to a separate component, said mounting plate being formed from two sheet metal plates secured to one another along adjacent faces, and both of said metal plates being solder coated on said one side; openings through the heat-transfer plates and the mounting plate defining oil and coolant passages communicating with the alternating channels between the stacked plates, said openings in said mounting plate having recesses therearound on said opposite side adapted to receive seals therein; and impressions in said adjacent face of one of said metal plates, said impressions being around said recesses to provide a solder depot. 2. The heat exchanger of claim 1, wherein said recesses are stamped out from the mounting plate. 3. The heat exchanger of claim 1, wherein said openings are stamped out from the mounting plate. 4. The heat exchanger of claim 1, wherein said mounting plate includes bores for fasteners securable to said separate component. 5. A heat exchanger for cooling oil, comprising: a plurality of pan-shaped heat-transfer plates stacked onto one another to define alternating channels for coolant and oil; a mounting plate soldered on one side to a side of the stacked plates, said mounting plate being adapted for mounting on its opposite side to a separate component; and openings through the heat-transfer plates and the mounting plate defining oil and coolant passages communicating with the alternating channels between the stacked plates, said openings in said mounting plate having recesses therearound on said opposite side adapted to receive seals therein, said seals comprising annular sealing members received in said recesses and sealing around said openings, said recesses including first and second recess portions around two of said openings and a slit between said annular recesses. 6. The heat exchanger of claim 5, wherein said mounting plate is formed from two sheet metal plates secured to one another along adjacent faces, and said recess is stamped out of one of said sheet metal plates. 7. The heat exchanger of claim 5, further comprising seals receivable in said recesses, each of said seals comprising two annular members receivable in said first and second recess portions and a connecting portion receivable in said recess slit. 8. The heat exchanger of claim 7, wherein said mounting plate is formed from two sheet metal plates secured to one another along adjacent faces. 9. The heat exchanger of claim 8, wherein both of said metal plates are solder coated on said one side.
