Heat Sink Calculator Free

Multiple heat sources attached to the heat sink can be evaluated.

Heat sink calculator free.

Heat sink temperature calculator. 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. When designing power electronics the heat dissipation of the device coupled with any heat sinks as well as.

Heat sink thermal resistance calculator use this online calculator to determine the heat sink thermal resistance required to maintain a specified component junction temperature.

The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. In our experience it generally estimates the overall heat sink volume within 15 of a final design. A reference link has been placed below the calculator for further reading.

Heat transfer design and engineering. How does the heat sink calculator work. Use this free online calculator to estimate the performance of a flat plate used as heat sink for leds mosfets diodes or other electronic or electrical devices. The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink.

However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow. The resistance to heat flow from the junction of the heat generating component through the casing thermal interface material heat sink and finally to environment is. The heat source is assumed to cover the entire base of the heat sink. Devices are encapsulated in packages which have different levels of thermal resistance.

Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions. Power components have a maximum junction temperature which must not be exceeded to prevent damage to the device. In addition the calculator automatically determines the optimal dimensions of your heat sink to achieve the lowest heat source temperature.
