Heat Sink Calculator Free

Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions.

Heat sink calculator free.

Power components have a maximum junction temperature which must not be exceeded to prevent damage to the device. The heat source is assumed to cover the entire base of the heat sink. Heat sink thermal resistance calculator use this online calculator to determine the heat sink thermal resistance required to maintain a specified component junction temperature. In addition the calculator automatically determines the optimal dimensions of your heat sink to achieve the lowest heat source temperature.

Heat sink convection with fins calculator. 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 heat sink size calculator is based on a well established equation for estimating heat sink volume during the early stages of heat sink design. How does the heat sink calculator work.

Calculate the thermal resistance and pressure drop of a plate fin heat sink and study how individual parameters affect the heat sink performance. This calculator uses the calculation methodology explained in the blog posts how to design a flat plate heat sink and performance of a led flat plate heat sink in multiple orientations. In our experience it generally estimates the overall heat sink volume within 15 of a final design. Heat sink temperature calculator.

The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink. Heat transfer design and engineering. 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. Heat transfer by convection of a heat sink with fins calculator and equations.

The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied. However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow.

The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling. A reference link has been placed below the calculator for further reading. Fins are used to increase heat transfer area and provide a cooling effect.
