Electric Cars
Reducing carbon emissions to mitigate global warming is a policy being strongly promoted by countries worldwide. Coupled with the increase in environmental awareness, the global sales of electric cars have been surging in recent years, becoming a new force that cannot be ignored in the global automobile market.
The important components of electric cars, such as battery modules, intelligent driving assistance systems, and even charging piles, will inevitably have overheating problems due to high-speed operations. Therefore, the key technology and material selection for heat dissipation are essential issues in emerging technologies today.
Thermal Utilization in Electric Cars
The core components of electric cars generate heat energy when in operation, and overheating is a stability killer for electronic devices. If heat dissipation is not effectively carried out, it will not only affect the efficiency and stability of operation, but may also seriously affect the normal driving of electric cars, resulting in safety issues. Therefore, a good heat dissipation solution is crucial for electric cars.
The heat dissipation solution needs to provide corresponding solutions for different systems such as battery modules, intelligent driving assistance systems, voltage converters, and in-car entertainment.
In-car Entertainment System
Due to the multifunctionality and high efficiency of car entertainment systems, "heat" issues will become more apparent, especially with image processing chips. High-definition audio and video require thermal pads with high thermal conductivity to transfer heat to the heat sink and exhaust it, or use heat pipes to bring concentrated heat sources to other areas to solve the problem of excessive concentration of heat sources, thus maintaining a stable and efficient entertainment experience.
ADAS Driving Assistance System
As the assisted driving function becomes more powerful, the systems contained in ADAS are also increasing, responsible for collecting and analyzing various information and outputting control signals through electronic control units (ECUs). They must also strictly control the temperature to prevent the system from failing to operate normally due to overheating.
Battery Module
Temperature is a critical factor affecting battery life and charge and discharge efficiency. The waste heat generated by the battery is transferred to the outer casing of the battery module through conduction for heat exchange. At the same time, it is applied to single-dose thermal conductive glue or dual-dose thermal sealing glue as a gap between batteries to achieve good temperature control effects for electric car batteries.
