Heat Sink Calculator Excel

The flow between the fins of the heat sink will the modeled as internal fully developed flow.

Heat sink calculator excel.

Values for l and h are first chosen based on your heat sink design constraints. Heat sink sizing calculations in order to calculate the heat transfer characteristics of the heat sink the convection coefficient h must be calculated. A fin n ed heat sink temperature distribution can be determined given heat sources. How does the heat sink calculator work.

The heat sink calculator is very useful when you are choosing power transistors heat sink etc. The heat source is assumed to cover the entire base of the heat sink. A reference link has been placed below the calculator for further reading. Heat sink convection with fins calculator.

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. Steady state or transient solutions are available for forced are natural convection. 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.

7 for air at stp pr 707. The heat sink calculator is easy to use enter the parameters except the one you want to calculate and then press calculate see example below. In our experience it generally estimates the overall heat sink volume within 15 of a final design. Et heat sink v1 0 this module is an excel com add in.

Fin spacing height and thickness. This tool is designed to calculate junction temperature of an electronic device typically power devices given four parameters. The convection heat dissipation q c1 from area a 1 the external side surfaces of the heat sink shown figure 2 is first. It has the following features.

Heat sink calculator is a tool for designing analysing and optimizing heat sink performance contact us today for custom heatsink solutions. The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling. Heat transfer by convection of a heat sink with fins calculator and equations. Fins are used to increase heat transfer area and provide a cooling effect.

The maximum ambient temperature the device s junction to package thermal resistance the thermal resistance of the heat sink and the power applied.
