環状熱交換器を軸方向に並列に並べている。 Recently, a cooling device having an annular heat exchanger has been proposed for the purpose of reducing noise and downsizing. In some cases, there are multiple objects to be cooled by such a cooling device. For example, construction machinery requires cooling of engine cooling water and hydraulic oil. In this case, a plurality of annular heat exchangers that cool each object to be cooled are arranged in parallel in the axial direction.

アン７の寸法が大きくなる。 In this cooling device, since one fan 7 blows cooling air to both heat exchangers 5a and 5b, it may not be possible to maintain the cooled bodies of the heat exchangers 5a and 5b at an appropriate temperature. . That is, for example, when the temperature of the object to be cooled in the heat exchanger 5a is low and the temperature of the object to be cooled in the heat exchanger 5b is high, the rotation speed of the fan 7 is increased to increase the cooling air volume, and the temperature of the object to be cooled in the heat exchanger 5b is increased. If an attempt is made to maintain the temperature of the object to be cooled in the heat exchanger 5a at an appropriate temperature, the object to be cooled in the heat exchanger 5a will be supercooled. If an attempt is made to maintain the temperature of the object to be cooled in the heat exchanger 5b at an appropriate temperature, the object to be cooled in the heat exchanger 5b will overheat. Furthermore, if one of the objects to be cooled is overcooled, the fan 7 is being driven more than necessary, and this energy loss cannot be ignored. moreover,
Since the required amount of air is supplied by one fan 7, the size of the fan 7 becomes large.
