Convective Cooling of a Potcore Inductor

Application ID: 2174

The inductor is a common component in a variety of electrical devices. Its applications include power transformation and measurements, and it can also be used together with capacitors to create oscillators. In small devices with many components, such as in laptops, heat generation can be a problem and must be accounted for in the design.

This axi-symmetric model studies the heat transfer in such a potcore inductor. It solves for the heat transfer inside the inductor and in the surrounding air, taking into consideration the air flow around the inductor.

The model accounts for both convective heat transfer as well as surface to surface radiation.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
