ABSTRACT:
A heat exchanger such as an oil cooler for exchanging heat between two fluids such as coolant water and oil in which the heat exchanger has a tank or casing through which coolant is circulated and containing a stack of heat exchange units each comprising a pair of plates joined together at peripheral edges but spaced apart to provide an oil path defined also by spacer means through the successive internal fluid chambers of the units and a coolant path also defined by spacer means between the units. The spacers between the units comprise sections of the plates making up the units and spacers. The disclosure also includes a bypass valve for bypassing most of the internal fluid chambers in the successive units when fluid such as oil is above a selected viscosity which indicates that much less cooling is required.
