Electric Vehicle Heat Dissipation Challenges
Lithium battery cells belong to the substable system, very sensitive to changes in temperature. Temperature is too low, lithium battery battery dynamics characteristics greatly reduced; while the temperature is too high, the capacity will be attenuated and thermal runaway risk will be greatly increased, so effective heat dissipation is an important measure to protect the new energy of the power battery. Inside the battery pack, the electric cell achieves effective heat dissipation by contacting with the heat sink and taking away the heat generated by the electric cell through the coolant.
However, there are micro-gaps and holes with uneven surfaces between the surface of the electric core and the heat sink, and if they are directly mounted together, the actual contact area is only about 10% of the base, and the rest is air gap. The thermal conductivity of air is only 0.024 W/m-degree, which is not conducive to heat dissipation and hinders heat conduction. The thermal conductivity interface material can exclude the air in the electronic equipment, and establish an efficient heat conduction channel between the electronic components and the heat sink, which can improve the efficiency of the heat sink.
TrumonyTechs Thermal Conductive Interfacial Materials
Thermal conductive interface materials are the general term for materials used to coat between heat sinks and heat generating devices to reduce the thermal resistance of contact between them. They are indispensable materials for new energy vehicles, energy storage, consumer electronics, communication equipment, industry and other fields, and their design concepts and development of production processes are greatly influenced by the needs of the application fields. Common thermally conductive interface materials include thermally conductive paste, thermally conductive gel, phase change materials, graphite flakes, sheet thermal gap fillers, liquid thermal gap fillers, and so on.

Classification and characteristics of thermally conductive interface materials
Thermal conductive interface materials need to have excellent thermal conductivity, insulation, fluidity, low coefficient of thermal expansion and other characteristics, according to its characteristics can be broadly divided into thermally conductive gel, thermally conductive silicone grease, thermal conductive gaskets and phase change materials.
Thermal conductive gel thermal conductivity of 0.85-2.5W/(m-K), with good compression deformation ability and stability, but the disadvantage is the need for a phase change material. It has good compression deformation ability and stability, but the disadvantages are that it needs curing treatment, stability test of peeling layer and thermal stress problem.
Thermal conductive silicone grease (thermal paste) thermal conductivity in the 0.4-6 W / (m-K), the advantages of thin thickness, adhesion, easy to process, cost-effective, but the disadvantage is prone to overflow and phase separation problems, easy to contaminate the substrate material in the process of use.
Thermal conductive gasket thermal conductivity in 0.8-3W / (m-K) advantages are good insulation, plasticity, cuttable, shock absorption, insulation, sealing, the disadvantage is that the high filler of thermal conductivity filler on the softness, which seriously limits the overall performance of the thermal conductive gasket.
Phase change thermal conductive organic materials thermal conductivity in the 0.7-1.5 W / (m-K), the advantage is solid at room temperature, easy to mass production, but low thermal conductivity.
