Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment and parts thereof, and in particular to an incoming line structure of an electric control module, an electric control module and a thermal management system using the same. Background Art

[0002] An energy storage system is a system used to store and release electrical energy. It involves the conversion between electrical energy and chemical energy, as well as the conversion between electrical energy and electrical energy. In the above process, a lot of heat will be generated. If the heat cannot be discharged in time, the temperature of the energy storage system will rise, bringing safety hazards, and thus affecting the performance, life and normal operation of the energy storage system.

[0003] In order to control the temperature of the energy storage system and improve the charging and discharging efficiency of the energy storage system, a thermal management system needs to be configured in the energy storage system to dissipate heat for the energy storage system.

[0004] The thermal management system in the prior art is usually equipped with electrically driven components such as compressors, electronic expansion valves, liquid cooling medium drivers (such as water pumps), water valves and fans. The above components will be integrated in a chassis / frame. At the same time, the above components require power input, signal input and signal feedback. Therefore, the thermal management system also needs to be equipped with an electronic control module, which is equipped with a controller, power electronic drivers (such as compressor frequency conversion drivers, special drivers for water pumps and fans, etc.), sensors and input / output interfaces (divided into power input / output interfaces and signal input / output interfaces).

[0005] In the above-mentioned electric control module, each component is integrated in an electric control box. Obviously, more cables (including power lines and signal lines, etc.) need to pass through the electric control box. Therefore, a wire hole needs to be opened in the electric control box.

[0006] Some thermal management systems require waterproof sealing performance for their electronic control modules. Although a cable gland can be configured at the wire hole of the electronic control box to make the wire hole of the electronic control box waterproof and sealed, when multiple cables need to pass through the electronic control box, a cable gland needs to be configured for each cable, which obviously increases the material cost and assembly cost of the equipment, and also increases the weight and volume of the equipment, and there is also the problem of inconvenience in subsequent inspection and maintenance.

[0007] The cables are integrated into a wiring harness, passed through the wire holes of the electric control box together, and the wire holes of the electric control box are filled with sealing material. The wire holes of the electric control box can also obtain waterproof sealing performance. However, there are certain gaps between the cables, and there are also certain gaps between the cables and the wire holes. It is difficult for the sealing material to fill the above-mentioned gaps one by one, and there is a risk of aging and failure of the sealing material. The inherent problem of inconvenience in subsequent inspection and maintenance still exists.

[0008] In summary, how to provide the electronic control module of the thermal management system with a wiring structure that has reliable waterproof sealing performance and is easy to inspect and maintain has become an urgent problem to be solved. Summary of the invention

[0013] In the above technical solution, the screw is provided with a gasket.

[0014] In the above technical solution, the line inlet structure of the electric control module of the present invention further includes a tightening fastener; the tightening fastener can tighten the sealing component body of the porous sealing component and apply pressure to the sealing component body.

[0015] In the above technical solution, the sealed wire-passing hole of the porous sealing component is used for one or several cables to pass through.
