Abstract

The present invention provides an electric vehicle power unit cooling system. The system at least comprises a generator cooling unit, a driving motor cooling unit and a heat radiator, after being connected with a cooling water inlet of the driving motor cooling unit in parallel, a cooling water inlet of the generator cooling unit is connected with a cooling water outlet of the heat radiator through a pipeline, and after being connected with a cooling water outlet of the driving motor cooling unit in parallel, a cooling water outlet of the generator cooling unit is connected with a cooling water inlet of the heat radiator through a pipeline. The connecting mode is equivalent to the mode that the generator cooling unit and the driving motor cooling unit are connected in parallel, and therefore the temperature of water entering the generator cooling unit and the temperature of water entering the driving motor cooling unit are consistent basically, the heat management environment of a generator and the heat management environment of a driving motor can be kept consistent, further, working conditions of the generator and working conditions of the driving motor can be kept consistent, the cooling effect of the generator and the cooling effect of the driving motor can be kept consistent, and the service life of an electric vehicle power unit can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a cooling system for a power unit of an electric vehicle. Background technique [0002] With the increasing scarcity of energy and the aggravation of environmental pollution, people's awareness of environmental protection is getting stronger and stronger. Electric vehicles, as an energy-saving and environment-friendly means of transportation, have been paid more and more attention by people. Since electricity can be obtained from a variety of primary energy sources, such as coal, nuclear energy, hydraulic power, wind power, light, heat, etc., people's worries about the depletion of oil resources are relieved. Electric vehicles can also make full use of the surplus electricity when the electricity consumption is low at night to charge, so that the power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Relevant studies have shown t...
