To220 heat sink calculator.

θ ja total is a value that we have to calculate which is easy to do and shown in the following sections of this article however for the time being assume you have it. The user can choose between natural or forced convection and or radiation for the modes of heat transfer. Power components have a maximum junction temperature which must not be exceeded to prevent damage to the device. Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance.

The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling. The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. When designing power electronics the heat dissipation of the device coupled with any heat sinks as well as. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters.

Devices are encapsulated in packages which have different levels of thermal resistance. Heat sink temperature calculator.

Free shipping on your first order shipped by amazon. Heat sink calculator is a software tool for designing analysing and optimizing heat sink performance. The thermal resistance of the heat sink and temperature of the power source is calculated. In our experience it generally estimates the overall heat sink volume within 15 of a final design.

The heat source is assumed to cover the entire base of the heat sink. Once we have this very important calculated figure we can use it in various inequalities shown. To determine if you need a heat sink for your voltage regulator there are some very simple parameters that you need to compare. Get it as soon as thu sep 17.

A reference link has been placed below the calculator for further reading. The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink.
