OIL COOLER FOR A VEHICLE WITH A BYPASS VALVE THAT IS ACTUATED BY A TEMPERATURE OF A WORKFLUID

摘要

An oil cooler for a vehicle has an inflow tank for inflow of working fluid. An outflow tank is spaced from the inflow tank by a predetermined distance and has a discharge hole at a side facing the inflow tank. A plurality of tubes connect the inflow tank with the discharge tank in the longitudinal direction, so that the working fluid flows through. A bypass valve is integrally attached to an outside of the one end portion of the inflow tank and connected to an inside of the inflow tank to divert the working fluid flowing therein or into the inflow tank by selectively opening and closing depending on a temperature of the working fluid. A drain line has one end attached to the discharge hole and another end attached to the bypass valve to connect the drain tank to the bypass valve.
