Abstract
A fluid temperature adjustment device that includes a circulation flow path that circulates the cooling water in one direction between the engine and the radiator; a first flow path branched from the circulation flow path at a location downstream of the engine and upstream of the radiator; a second flow path branched from the circulation flow path at a location downstream of the radiator and upstream of the engine; a third flow path that communicates with a cooling water outlet of the heat exchanger and that is merged with the circulation flow path at a location downstream of the radiator and upstream of the engine; and a switching valve that selectively communicates between one of the first and second flow paths and a cooling water inlet of the heat exchanger.
