Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] like figure 1 - The arrangement structure of the cooling system of the hybrid electric vehicle shown in 16, including the engine cooling system, the air conditioning cooling system and the motor cooling system.

[0036] The layout structure of the engine cooling system has the following two types:

[0037] Structure 1: The engine cooling system includes an engine radiator 3 and a fan 4 arranged at the air intake of the air intake grille 1 in the middle and arranged in sequence along the axial direction of the vehicle, such as figure 2 As shown, the engine cooling system also includes an intercooler 7 and an oil cooler 8 respectively arranged at the air intakes of the side air intake grilles 2 on the left and right sides of the vehicle. An intercooler guide structure is set between the intercooler 7 and the side air intake gr...

Abstract

The invention discloses an arrangement structure of a hybrid electric vehicle cooling system, which comprises an engine cooling system, an air conditioner cooling system and a motor cooling system, and is characterized in that the engine cooling system is arranged at an air inlet of a middle air inlet grille of a vehicle and an air inlet of a side air inlet grille of the vehicle, the air conditioner cooling system is arranged at the air inlet of the middle air inlet grille, and the motor cooling system is arranged at the air inlet of the lower portion of the middle air inlet grille; and an engine cooling flow guide structure is arranged between the engine cooling system and the side air inlet grille, an air conditioner cooling flow guide structure is arranged between the air conditioner cooling system and the middle air inlet grille, and a motor cooling flow guide structure is arranged between the motor cooling system and the lower portion of the middle air inlet grille. The engine cooling system, the air conditioner cooling system and the motor cooling system are arranged in different areas and correspond to the air inlet grilles of all the areas, and then the air inlet requirement of all the cooling systems is met. The air inlet amount of each cooling system is increased, and the cooling performance of each cooling system is improved.

Description

technical field [0001] The invention relates to the technical field of the cooling system of a hybrid electric vehicle, in particular to an arrangement structure of a cooling system of a hybrid electric vehicle. Background technique [0002] The range-extended electric vehicle is a series hybrid. The whole vehicle contains two systems (pure electric system and range extender system). The lower body has both three electric systems and an engine system and cooling system. The layout of the cooling system is complex. Whether the space is suitable or not affects the performance of the related vehicle, so the layout of the cooling system is a major difficulty in the range-extended electric vehicle. The engine itself has a set of heat dissipation device and fan, the motor and the controller have their own heat dissipation system, and there are also a number of systems such as the air conditioner condenser and the engine intercooler, especially the intercooler is generally arranged...
