Abstract
In an arrangement for the cooling of vehicle components comprising a first coolant circuit including a first component to be cooled, a radiator with cooling fan and a coolant pump for circulating coolant through the first component and the radiator, a by-pass line arranged in parallel flow relationship with the radiator and including a second heat exchanger with a fan for providing heated air for the passenger compartment of the vehicle and a control valve for controlling the flow of coolant through the by-pass line and the second heat exchanger, there is provided a second coolant circuit which extends also through the second heat exchanger separately from the first coolant circuit and includes an additional component to be cooled.
Claims8
An arrangement for the cooling of components of a vehicle comprising:
- a first coolant circuit with a first component to be cooled, a first heat exchanger with a cooling fan for blowing cooling air through said first heat exchanger, a coolant pump for circulating the coolant, a by-pass line arranged in parallel flow relationship with said first heat exchanger and including a second heat exchanger with a second cooling fan for blowing air through said second heat exchanger for heating said air, a control valve for controlling the flow of coolant through said by-pass line, a second coolant circuit also extending through said second heat exchanger in separate flow relationship from said first coolant circuit and including at least one additional component to be cooled and a control unit for controlling operation of said coolant pump, said cooling fans and said control valve, depending on operating parameters of the vehicle by sensors connected to said control unit.
