For most electronic products, the operation will continue to heat, and the temperature rise exceeds a certain limit, which may cause the performance of electronic products to be reduced, or even the electronic products can not be damaged, and the electronic components may burst and cause fire. In order to ensure the normal operation of electronic products, the temperature of the circuit needs to be controlled within the appropriate temperature range, and the inductance coil is a very common electronic component of electronic products, so how to deal with the heat accumulation problem of the inductor coil?
1. The most common way to deal with heat accumulation is physical heat dissipation, and the most effective and reliable physical heat dissipation is to use air-cooled and radiator. Air-cooled and heat sinks can change the air around the inductor coil by exchanging them, replacing hot air with cold air, cooling various high-heat electronic devices and reducing the impact of heat on the circuit. Taking the computer as an example, the air-cooled and radiator can take away the heat through the heat sink, which can control the high-temperature CPU at 35~45 degrees Celsius for a long time during operation, of course, the disadvantage of the air-cooled and radiator is that it will produce vibration and noise, and it is only suitable for traditional or modern equipment such as computers, auto parts and equipment, inverters, hardware tools, refrigeration equipment, etc.
2. Thermally conductive adhesive and heat dissipation paste are also common heat dissipation materials for inductance coils, with excellent thermal conductivity. Its function is to apply it to the surface of the inductance coil, fill the gap between the inductance coil and the heat sink, so that the two can achieve full contact, effectively conduct the heat to the heat sink, and the heat sink absorbs the heat and dissipates it to the outside of the circuit, keeping the temperature of the circuit normal. Secondly, heat dissipation paste has stable chemical properties such as thermal conductivity, temperature resistance, and insulation, which is an effective means to improve the heat dissipation ability and stability of electronic components.
3. The specific heat capacity of the liquid is generally larger, so the water-cooled radiator has more high-performance radiator capacity than the traditional air-cooled radiator. Water-cooled heat sinks use coolant to indirectly contact inductor coils or other electronic components, and the heat sink is responsible for absorbing this heat to keep the circuit at a normal temperature. The advantages of water-cooled radiators are that they have the advantages of quietness, stable cooling, and less dependence on the environment. The disadvantage is that the stability is worse than that of air-cooled radiators, and the cost is relatively high, and the volume and weight are relatively large.
4. Each electronic component in each circuit has thermal impedance, and the size of the thermal impedance value can reflect the heat transfer capacity of the medium or the medium. The magnitude of the thermal impedance value varies depending on the material, the external area, the purpose of use, and the installation location. The use of thermally conductive electronic components with high thermal conductivity is the most traditional and effective way to reduce the heat conduction of inductor coils.
