Vehicle heat exchange system and dump truck

A vehicle heat exchange system comprising:

• a plurality of cooling fans for generating a flow of cooling air;
• a high-temperature side radiator unit configured to transfer heat between a cooling liquid discharged from a high-temperature heat source and the cooling air generated by the plurality of cooling fans, and supply the cooling liquid to the high-temperature heat source again;
• and
• a low-temperature side radiator unit configured to transfer heat between the cooling liquid discharged from a low-temperature heat source whose temperature is less than that of the high-temperature heat source and the cooling air generated by the plurality of cooling fans, and supply the cooling liquid to the low-temperature heat source again,
• wherein
• the high-temperature side radiator unit includes:
• a first high-temperature side radiator that faces a first fan, which is a part of the plurality of cooling fans, and is connected to a high-temperature side discharge pipe for discharging the cooling liquid from the high-temperature heat source;
• a second high-temperature side radiator that faces a second fan, which is different from the first fan among the plurality of cooling fans, and is connected to a high-temperature side supply pipe for supplying the cooling liquid to the high-temperature heat source;
• 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 includes:
• a first low-temperature side radiator that is arranged so as to face the second high-temperature side radiator on an upstream side of the flow of the cooling air, and is connected to a low-temperature side discharge pipe for discharging the cooling liquid from the low-temperature heat source;
• a second low-temperature side radiator that is arranged so as to face the first high-temperature side radiator on the upstream side of the flow of the cooling air, and is connected to a low-temperature side supply pipe for supplying the cooling liquid to the low-temperature heat source;
• 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.
