Integrated cooling system and electric driving system of automobile

Abstract

The invention provides an integrated cooling system and an electric driving system of an automobile. The integrated cooling system comprises a first cooling pipeline (11) capable of cooling an electric motor (21) of an automobile. A second cooling line (12) capable of cooling the transmission (22) of the vehicle; A third cooling line (13) capable of cooling the controller (23) of the vehicle; Wherein the first cooling pipe line (11) and the second cooling pipe line (12) are in parallel or in series; And / or wherein the first cooling line (11) and the third cooling line (13) are arranged in parallel or in series; And / or wherein the second cooling line (12) and the third cooling line (13) are configured in parallel or in series. The invention can integrate the original three mutually independent liquid cooling systems into a three-in-one system, so that the whole driving system is compact in structure, the occupying space of the engine room is reduced, the weight is reduced, and the battery range is increased.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an integrated cooling system and an electric drive system for automobiles. Background technique [0002] In recent years, with the vigorous advocacy of national policies, the field of new energy vehicles has developed rapidly, and competition in the industry has also increased. From a technical point of view, improving the power density of the main drive system, efficient cooling of the system, and system integration are unavoidable directions. . [0003] The patent No. ZL201510488880.6 discloses a motor oil cooling system. In this patent, the motor with a casing is placed inside the gearbox, and the oil in the gearbox is sprayed on the outer surface of the motor by a pump to achieve simple integration. . The heat inside the motor can only be taken away by the oil after being conducted through the casing, the cooling effect is not good, the thermal load of the m...
