Abstract: An arrangement and a method for cooling coolant in a cooling system in a vehicle: The cooling system includes a first cooling circuit, a first coolant pump (11) to circulate coolant through the first cooling circuit, a first radiator (13) to cool the coolant, and a thermostat (12) which opens to direct coolant to the first radiator (13) when the coolant is above the thermostat's regulating temperature (t2); and a second cooling circuit includes a second radiator (20) to cool coolant. A flow device (23, 29) selectively transfers a portion of coolant from the first cooling circuit to the second cooling circuit, so that this portion of the coolant is cooled in the second radiator (20) when the coolant in the first cooling circuit is within a temperature range defined by a lowest temperature (t1) at which the coolant initially needs cooling and a highest temperature which is equal to the thermostat's regulating temperature (t2).

Abstract: A thermostat device (8) for a cooling system in a vehicle. The device (8) includes a thermostat housing (15) enclosing a movably arranged valve body (16, 20, 34, 44). The valve body is configured to distribute coolant from a thermostat chamber (15a) to a radiator bypass line (9) and/or a radiator (11) in dependence on the position of the valve body. The device (8) has a first thermal expansion element (31) providing a first stroke of a valve body (16, 20, 34, 44) in response to the temperature of the coolant in a the pilot chamber (14a), and a second thermal expansion element (32) providing a second stroke of the valve body (16, 20, 34, 44) in response to the temperature of the coolant in the thermostat chamber (15a) such that the valve body (16, 20, 34, 44) is moved to a position defined by the strokes from the thermal expansion elements (31, 32). The pilot chamber (14a) has an outlet passage (14b) for directing coolant from the pilot chamber (14a) to the thermostat chamber (15a).

Abstract: A cooling arrangement for a WHR-system in a vehicle, includes a first cooling circuit including a first radiator in which a circulating coolant is cooled, and a second cooling circuit including a second radiator in which a coolant is cooled to a lower temperature than the coolant in the first radiator. A condenser inlet line directs coolant from one of the cooling circuits to a condenser to provide cooling for a working medium flowing therethrough. A cooling adjusting device adjusts the temperature of the coolant in the inlet line to the condenser by the coolant in the other cooling circuit based on information received about the coolant such that the coolant in the condenser inlet line provides the estimated suitable cooling of the working medium in the condenser.
