This generator set is provided with an airflow path which has an air inlet and an air outlet and through which a cooling air flows, a power generator, an alternator which is driven by the power generator, and a radiator which is installed in the airflow path, with a cooling medium circulating between the power generator and the radiator, wherein the inflow area of the cooling airflow into the radiator is greater than the passage area of the air inlet.

A heat accumulating unit includes an upstream heat accumulator and a downstream heat accumulator each accommodating a supercooling heat accumulating material. Each of the upstream heat accumulator and the downstream heat accumulator has a channel in which fluid flows. In heat accumulation of the supercooling heat accumulating material, the channel of the upstream heat accumulator and the channel of the downstream heat accumulator are set in a serial connection state by a serial connection pipe. In a temperature rise mode, fluid that has passed through the channel of the upstream heat accumulator flows in a bypass pipe.

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).
