Problems solved by technology

In addition, the temperature of the brake disc system is different under different working conditions. When braking, the temperature rise of the brake system will increase sharply. If the heat cannot be effectively dissipated, the life of the brake disc will be greatly shortened, and even bring safety hazards

Abstract

The invention discloses a comprehensive thermal management system for an embedded hub motor of an electric vehicle based on a chemical solution. The system comprises an embedded magnetic steel heat dissipation system and a brake disc spiral flow deflector heat dissipation system; the embedded magnetic steel heat dissipation system comprises embedded magnetic steel, an electromagnetic valve A, a temperature sensor A, a solution return pipe, a steam return pipe A, a condensation water storage tank, a solution pump A, an integrated solution storage tank, a booster pump, a fan, a power supply, a controller, a solution pump B and a solution pump C; the brake disc spiral flow deflector heat dissipation system comprises a brake disc spiral flow deflector, an electromagnetic valve B, a temperaturesensor B, a gas-liquid separator, a solution return pipe B, a steam return pipe B, a condensation water storage tank, a solution pump A, an integrated solution storage tank, a booster pump, a fan, apower supply, a controller, a solution pump B and a solution pump C. The comprehensive thermal management system has the advantages that heat of a coil of the embedded hub motor is collected, transmitted and dissipated, and a pulse thermal load generated by a brake disc is converted into a steady thermal load.

Description

technical field [0001] The invention relates to the technical field of hub motor thermal management systems, in particular to a comprehensive thermal management system for embedded hub motors of electric vehicles. Background technique [0002] With the rapid development of my country's economy, the number of motor vehicles in the country is increasing at a rate of 3.5% per year. The increase in car ownership not only causes an energy crisis, but also the harmful substances emitted by cars have become an important source of air pollution, which has caused extremely adverse effects on people's production and life. Transportation energy consumption has become the main source of local environmental pollution and global greenhouse gas emissions, and people have to turn their attention to the development and utilization of new energy vehicles. The data shows that compared with traditional fuel vehicles, electric vehicles can reduce CO emissions every 100km. 2 It is 7.6kg. Among...
