Patent attributes
A heat exchanger assembly has a first heat exchanger with a first heat radiating area receiving a first cooling fluid, a second heat exchanger with a second heat radiating area receiving a second cooling fluid and a third heat radiating area receiving a third cooling fluid. In use, the difference in temperature between the first cooling fluid entering and exiting the first heat radiating area is greater than the difference in temperature between the second cooling fluid entering and exiting the second heat radiating area and greater than the difference in temperature between the third cooling fluid entering and exiting the third heat radiating area. The temperature of the second cooling fluid flowing through the second heat radiating area is higher than the temperature of the third cooling fluid flowing through the third heat radiating area.
