How to Manage Heat Dissipation with Non-Metal Electrical Enclosures
When you run things on electricity, you get a lot of extra heat for your troubles. It’s pretty simple. When electricity flows through anything, there is resistance, and that resistance creates heat. If you have enough electricity flowing, the heat can build up excessively, and it creates problems. In fact, there’s a feedback loop that occurs. As wires get hotter, they create more resistance, and thus more heat. Needless to say, heat management matters a lot for electricity, and sometimes, that can be tricky. Many electric components need protection from the elements, so we put them in enclosures. But enclosures can trap heat, causing you to trade one problem for another. It’s all manageable when you learn the essentials of heat dissipation. As it applies to non-metal electrical enclosures , there are really three concepts you need to learn: radiation, surface area, and ventilation. Radiation The primary way enclosures dissipate heat is through radiation. In a manner of speakin...
