Accordingly, a PE cooling circuit for cooling the PE parts by circulating coolant and a battery cooling circuit for cooling the battery by circulating coolant are provided. Additionally, a radiator circulation line through which the coolant is cooled via the radiator may be further provided.

Accordingly, in a connected operation mode in which coolant passes through the radiator circulation line, there may be a problem in which the flow of coolant to the radiator circulation line is impeded, and since the reservoir is not placed in front of the radiator in that operation mode, there may be a momentary lack of coolant replenishment. This may cause problems such as increased noise and reduced cooling performance.

- the highest height of the second unit tank body 100-2 that is, the highest height of the third space 103, is the lowest water level (Min) preset in the first unit tank body 100-1, that is, the first space ( 101) and the second space 102 may be formed lower than the preset minimum water level (Min).
- the coolant inlet 200 may be configured as one, so that the single coolant inlet 200 may be disposed at the top of the first unit tank body 100-1 and at the vertical top of the first partition 310. Additionally, the height of the first partition wall 310 may be formed to be higher than the highest water level (Max) preset in the first tank body 100-1. Since the reason or principle for adopting the above configuration is substantially the same as described in the previous example, detailed description will be omitted.
- the reservoir tank of the present invention includes three spaces partitioned from each other, where the first space and the second space are in communication with each other, and the third space is separated from the first space and the second space to form an independent space. Accordingly, the problem of insufficient coolant replenishment when operating the cooling system can be solved, and the maximum height of the third space can be set lower than the lowest water level of the first space and the second space to prevent cooling performance deterioration due to coolant bypass. As the coolant inlet is formed into one, coolant injection into the cooling system is improved and manufacturing costs can be reduced.
