Abstract
The present invention is to connect the engine and PE parts in parallel to one water pump so that the engine and PE parts can be cooled smoothly with fewer parts, contributing to reducing the cost and weight of the vehicle, improving the NVH performance of the vehicle It can be used to secure a relatively advantageous characteristic in terms of securing an installation space in a vehicle.
Description
The present invention relates to a cooling system for a hybrid vehicle, and more particularly, to a cooling system for a vehicle requiring both cooling of an engine, which is an internal combustion engine, and cooling of a power electronic component (PE) for driving an electric motor. to be.
In addition to the cooling route for cooling the engine, the hybrid vehicle should be further provided with a cooling route for cooling the PE parts. In the conventional hybrid vehicle, as shown in FIG. It is provided.
The independent cooling structure as described above requires a plurality of water pumps to increase the weight and cost of the vehicle, and noise and vibration generated when the plurality of water pumps are operated act as a deterioration of the NVH performance of the vehicle. Done.
In addition, a relatively large number of hoses are required to form two independent cooling routes, which, together with a plurality of water pumps as described above, act as a detrimental factor in securing an installation space in a vehicle.
The present invention has been made in view of the above problems, by connecting the engine and the PE parts in parallel to one water pump to enable the cooling of the engine and PE parts with fewer components, the cost of the vehicle The present invention aims to provide a cooling system for a hybrid vehicle that contributes to weight reduction, contributes to improving the vehicle's NVH performance, and is relatively advantageous in terms of securing space in the vehicle.
Cooling system of the present invention hybrid vehicle for achieving the above object is
A dual pump having separate first pumps and second pumps on both sides of the motor rotor;
An engine side cooling route connected to the first pump of the dual pump;
A PE component side cooling route connected to the second pump of the dual pump;
A reservoir tank commonly connected to both the engine side cooling route and the PE component side cooling route, and connected to the first pump and the second pump of the dual pump;
And a control unit.
The present invention is to connect the engine and PE parts in parallel to one water pump so that the engine and PE parts can be cooled smoothly with fewer parts, contributing to reducing the cost and weight of the vehicle, improving the NVH performance of the vehicle In addition, it is possible to secure a relatively advantageous characteristic in terms of securing an installation space in the vehicle.
