Problems solved by technology

[0011] 1. The auxiliary heat dissipation system and the heat dissipation system of the vehicle motor electric control mainly work when the ambient temperature is high, and the utilization rate is not high
[0012] 2. Each cooling system is independent, which increases the cost
[0013] 3. Each heat dissipation system has complementary features, and the complementary features are not utilized. The performance indicators are not optimal (such as improving cold start performance and efficiency) and at the same time waste energy and cause damage to equipment (such as electric control of motors in winter. waste and reduced fuel cell life, etc.)
However, the heating system used in this patent is not a certain configuration of the vehicle, and it cannot be implemented in places without a heating device.
In addition, it does not use the feedback current, and does not manage the heat system of electrical equipment such as motor electric control in a unified manner.

Abstract

The invention discloses a vehicle integrated thermal management system, comprising a first cooling water channel and a second cooling water channel, wherein a power battery and a first radiator assembly are connected in series in the first cooling water channel; a control assembly, a motor and a second radiator assembly are connected in series in the second cooling water channel; the first radiator assembly and the second radiator assembly are connected in parallel with one heat exchange assembly, two ends of the heat exchange assembly are connected with two ends of the first radiator assemblyand the second radiator assembly through pipelines. The vehicle integrated thermal management system of the invention has the advantages of reducing cost, saving energy, organically ordinating heat on a vehicle and so on.

Description

technical field [0001] The invention mainly relates to the technical field of thermal management, in particular to a vehicle integrated thermal management system. Background technique [0002] Hydrogen energy is known as the "ultimate energy source" in the 21st century. It has the characteristics of wide source, storable, renewable, electric and combustible, zero pollution, zero carbon emission, etc. It helps to solve the problems of energy crisis and environmental pollution. [0003] The United States, Canada, the European Union, Japan and South Korea have all taken substantial steps in the industrial application of hydrogen energy. Both the government and industrial capital are actively promoting the development of the hydrogen energy industry. Some cities in Europe have started trials of a hydrogen energy society, and the Japanese government has proposed to build a "hydrogen energy society" and to turn the 2020 Tokyo Olympics into a "hydrogen energy event". [0004] As t...
