<p>A heat exchanger is disclosed for automotive lubricants and coolants wherein the heat exchanger has a calibrated bypass orifice (36) located therein to maintain the flow therethrough at all times, particularly during cold flow operation, or high pressure transient conditions such as at engine start-up. The heat exchanger has a housing (16) defining a fluid inlet chamber (18) and a fluid outlet chamber (20). A separator (34) is located between the inlet and outlet chambers and heat exchange passages (24) are located between and communicate with the inlet and outlet chambers. The separator (34) has a calibrated bypass orifice (36) therethrough for the continuous flow of fluid between the inlet and outlet chambers bypassing the heat exchange passages.</p> |
