Electric car cooling waterway, electric car cooling system and electric car

Abstract

Disclosed is an electric car cooling waterway. The electric car cooling waterway comprises at least two unit waterways (5, 6). Each unit waterway respectively passes through different parts, to be cooled, of the electric car, and two ends of each unit waterway are respectively communicated with a water inlet chamber (2) and a water outlet chamber (3) of a radiator (1) to respectively form a circulating waterway. In addition, the invention further provides an electric car cooling system provided with the electric car cooling waterway and the electric car. According to the electric car cooling waterway and the electric car cooling system formed by the electric car cooling waterway, through the formation of more than two independent or shunt-wound cooling circulation waterways, the number of parts to be cooled on each unit waterway is enabled to be relatively reduced, and therefore arrangement of waterways is simplified, flow resistance of cooling water is notably reduced, the cooling water is enabled to circulate smoothly, and therefore each parts, to be cooled, of the electric car can be effectively cooled.

Description

technical field [0001] The invention relates to an automobile cooling system, in particular to an electric automobile cooling water circuit. Further, the present invention relates to a cooling system having the electric vehicle cooling water circuit. In addition, the invention also relates to an electric vehicle. Background technique [0002] At present, the development of electric vehicles is getting faster and faster, and components such as motors and controllers used for power output need to be cooled to ensure their performance. Existing electric vehicles usually use water cooling systems for heat dissipation and cooling. Therefore, the cooling water circuit circulation of the electric vehicle cooling system is very important. [0003] The existing electric vehicle cooling waterway basically adopts a series waterway, that is, the cooling waterway passes through each component that needs to be cooled on the electric vehicle and then flows into the radiator, thereby form...

AI Technical Summary

Problems solved by technology

However, such high-performance water pumps are still lacking at home and abroad, and the price is high.

[0004] In particular, with the increasing number of integrated functions on electric vehicles, the number of units that need to be cooled is also increasing, especially in large-scale pure electric vehicles, which have multiple motors and controllers, resulting in complex cooling water circuits and large water resistance in the cooling system. As a result, the local cooling water circulation is not smooth or difficult, and the local water temperature of the cooling unit is high. At the same time, the performance of the electronic water pump is low, and it cannot meet the complex water circuit circulation function. Due to the many cooling units, the water circuit is complicated.

This often results in the parts that need to be cooled on the electric vehicle not working properly because they cannot be cooled effectively, which leads to the failure of the electric vehicle

[0005] Therefore, the traditional simple series cooling water circuit can no longer meet the cooling performance requirements of electric vehicles today.
