CA 2113519
A heat exchanger is disclosed for automotive lubricants and coolants wherein the heat exchanger has a calibrated bypass orifice 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 defining a fluid inlet chamber and a fluid outlet chamber. A separator is located between the inlet and outlet chambers and heat exchange passages are located between and communicate with the inlet and outlet chambers. The separator has a calibrated bypass orifice therethrough for the continuous flow of fluid between the inlet and outlet chambers bypassing the heat exchange passages.
