- the heat dissipation component when the cold plate 300 adopts air-cooling for heat dissipation, the heat dissipation component includes a fan, and the fan drives the internal airflow of the cold plate 300 to exchange heat with the cold air of the external environment to cool the cold plate 300 , and then uses the cold plate 300 to cool the first circuit board 120 and a second circuit board 220 .
- the heat dissipation system may include one or more control modules 10 .
- the vehicle includes a vehicle frame and a heat dissipation system as described above.
- the heat dissipation system is installed on the vehicle frame.
- Vehicles refer to wheeled vehicles driven or towed by power devices and used for people traveling on the road or for transporting items and performing special engineering operations.
- Vehicles include two-wheeled, three-wheeled or four-wheeled vehicles.
- Vehicles also include various special operation vehicles with specific functions, such as engineering rescue vehicles, sprinkler trucks, sewage suction trucks, cement mixer trucks, crane trucks, medical vehicles, etc.
- the vehicle can be an electric vehicle or a fuel vehicle.
- the electric vehicle can be, but is not limited to, a pure electric vehicle (Pure Electric Vehicle/Battery Electric Vehicle, PEV/BEV), a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), or a range-extended vehicle. This application is not limited to electric vehicles (Range Extended Electric Vehicle, REEV), plug-in hybrid electric vehicles (Plug-in Hybrid Electric Vehicle, PHEV), and new energy vehicles (New Energy Vehicle).
- the frame As the structural skeleton of the vehicle, the frame is used to support, fix and connect the vehicle's heat dissipation system, and bear the loads inside the vehicle system and from the external environment.
- the electronic control unit equipment in the vehicle will generate heat.
- the heat dissipation system can enable the electronic control unit and other electronic equipment to obtain good heat dissipation, ensuring that the electronic control unit can work stably and with high performance. It should be understood that one or more heat dissipation systems may be included in the vehicle, and the application of the heat dissipation system may not be limited to vehicles, but may also be applied to other mechanical equipment.
