| 摘要 |
The invention relates to a cooling system for an internal combustion engine (12) on a vehicle, preferably for an agricultural or industrial commercial vehicle, in particular, for a tractor. The cooling system (10) comprises a high temperature circuit (14) and a low-temperature circuit (20). The high temperature circuit (14) is provided for cooling the internal combustion engine (12) and comprises at least one cooler (18). The low temperature circuit (20) is provided for cooling a charge air cooler (22) and, optionally, an oil cooler (24) and comprises at least one cooler (26). The charge air cooler (22) is embodied with at least two parts or in two stages. According to the invention, the cooling system shall have an improved power capacity, whereby said cooling system (10) is characterised in that, in the direction of flow of coolant in the low temperature circuit (20), the cooler (26) is arranged after a part (46) of the charge air cooler (22), the oil cooler (24) and a further part of the charge air cooler (44). Alternatively or additionally a further cooling circuit (36) is provided, by means of which the charge air cooler (22) may be cooled and which comprises at least one cooler (38).
