How to reduce the influence of inductor coil heat on the circuit | GETWELL

In the circuit design process, the heat generated by the induction coil is an important part of the circuit.Heat will lead to the rise of the inductance coil temperature, temperature has a great influence on the inductance coil, coil resistance generally increases with the rise of temperature.So, how to reduce the effect of heat on the coil?The following is a summary of the professional inductor manufacturers of Getwell to you.

There are usually several ways to reduce the influence of the heat conduction of the induction coil on the circuit:

1. In each circuit, each electronic element has a thermal impedance, the value of which can reflect the heat transfer capacity between or between mediums.The value of thermal resistance varies with the material, the area of the outer wall, the use and the location of installation.Using thermal impedance electronic components with high thermal conductivity is a traditional and effective method to reduce the heat conduction of inductor coils.

2. In terms of heat dissipation, the most widely used cooling fan exhaust heat on the market at present.Converts hot air around the induction coil to forced convection cold air, thereby continuously transferring heat from the circuit to the surrounding air.Generally speaking, the cooling fan can effectively enhance the heat dissipation of 30%, the disadvantage is that it will produce vibration and noise, and it is only suitable for traditional or modern equipment such as large volume computers, auto parts, frequency converters, hardware tools, refrigeration equipment and so on.

3. The thermal dispersion layer is directly constructed on the surface of the object (induction coil) to dissipate and cool, absorbs heat energy and heats it at the same time, absorbs heat energy and radiates heat dissipation to the outer space at the same time.At the same time, it can improve the properties of self-cleaning, insulation, corrosion resistance, moisture resistance and so on. It is a new method to reduce the influence of induction coil heat conduction on the circuit.

4. The thermal conductivity and hot melt of liquid are larger than that of gas, so the cooling by liquid cooler will be more effective than the cooling by fan.Direct or indirect contact with the generator coil or other electronic components, through the coolant to emit heat, heat out of the circuit.Its disadvantage is higher cost, volume weight, difficult to maintain.

5. The effect of thermal conductivity adhesive glue and heat paste like literally, has the extremely good thermal conductivity, can effectively improve the circuit in the electronic components of the cooling capacity, is often used for coating on the surface of the electronic components (inductor), the quantity of heat to the radiator (copper or aluminum), after the heat radiator to external heat emission circuit, maintain circuit temperature is normal.Second, the cooling paste has a certain moistureproof, dustproof, anti-corrosion effect, is to improve the electronic components cooling performance and stability of the effective means.

The above is the inductor supplier's introduction on how to reduce the influence of inductor coil heat on the circuit. I hope it can help you.For more information on high-frequency transformers, search "inductorchina.com" and consult us.
