A heat sink’s primary function is to keep a device’s temperature below the maximum temperature permitted by the device’s manufacturers. Thermal management is essential for the performance, durability, and safety of electric vehicles. Electric car batteries are prone to temperature fluctuations brought on by both internal and external sources. If exposed to temperatures outside their ideal range, they may suffer damage or degradation.
This is especially important while operating in extremely hot or cold conditions or when charging quickly. Thermal management plates for Senior Flexonics batteries are made to control temperatures, ensuring that performance, safety, and battery life are all maximised. When two objects with different surface temperatures come in touch, thermal conduction occurs. The fast molecules of the hotter substance collide with the slow moving molecules of the colder object in this process.
Energy is transferred from the hot object to the cooler object as a result. Thus, a heat sink uses conduction and subsequently convection to transport heat from a high-temperature component, like a transistor, to a low-temperature medium, like air, oil, water, or any other suitable medium.
The Global EV Aluminum heat sink Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A heat sink is an electronic device used to dissipate extra heat that is typically attached to an electronic device and constructed of good thermal conductivity material. It is used to cool the circuit parts by dispersing extra heat to avoid overheating and early component failure as well as to increase the parts’ dependability and performance.
In order to maximise the surface area in contact with the cooling medium, such as air, the heat sink is typically built to function as a heat exchanger. The material, surface treatment, physical characteristics including protrusion design, air velocity, and attachment techniques all affect performance.
Among the materials utilised between a component’s heat spreader surface and the heat sink surface to enhance heat transmission and, consequently, heat sink performance are thermal pastes, compounds, and conductive tapes.
Fourier’s law of heat serves as the foundation for heat sink operation. Heat moves from high temperature regions to lower temperature regions whenever there is a temperature differential in a body. Radiation, conduction, and convection are the three methods through which heat can be transmitted.
