Abstract

See full text

Provided is a technique for improving the cooling efficiency of a vehicle heat exchange system configured to cool a cooling liquid discharged from each of a plurality of heat sources. The vehicle heat exchange system comprises a high-temperature side radiator unit and a low-temperature side radiator unit, the high-temperature side radiator including: a first high-temperature side radiator that faces a first fan and is connected to a high-temperature side discharge pipe; a second high-temperature side radiator that faces a second fan and is connected to a high-temperature side supply pipe; and a high-temperature side connection pipe for supplying the cooling liquid from the first high-temperature side radiator to the second high-temperature side radiator, and the low-temperature side radiator unit including: a first low-temperature side radiator that is arranged to face the second high-temperature side radiator on the upstream side of the cooling air flow, and is connected to a low-temperature side discharge pipe; a second low-temperature side radiator that is arranged to face the first high-temperature side radiator on the upstream side of the cooling air flow, and is connected to a low-temperature side supply pipe; and a low-temperature side connection pipe for supplying the cooling liquid from the first low-temperature side radiator to the second low-temperature side radiator.
