Calculate Thermal Resistance Heat Sink

Heat sink thermal resistance delta t for each component part of the heat sink.

Calculate thermal resistance heat sink.

Multiple heat sources attached to the heat sink can be evaluated. P d power dissipated 45 w. 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 heatsinkcalculator offers online heat sink analysis software that allows you to analyze plate fins heat sinks cooled via radiation and natural or forced convection.

In addition the calculator automatically determines the optimal dimensions of your heat sink to achieve the lowest heat source temperature. How to calculate thermal resistance of a heat sink in an enclosure the structures in the enclosure do not significantly obstruct the movement of air flow throughout the enclosure air flow through the heat sink is not restricted due to the lack of ventilation in the enclosure radiation exchange. Multiple heat sources attached to the heat sink can be evaluated. Heat sink thermal resistance calculator.

Fin pack air fin to air and fin delta ts interface materials tim and base to fin usually solder and the base both solid metal and vapor chamber bases are shown. Jsa heat sink thermal resistance required 0 222222222222 w. Thermal conductivity of material w mk or. R1 r 1 thermal resistance of device junction to air if no heat sink or thermal resistance of heat sink r2 r 2 thermal resistance of device junction to air applications of a heat sink calculator the highest operating temperature that a semiconductor in an electronic device can withstand is called its junction temperature.

This tool is designed to calculate the heat dissipation and the heatsink thermal resistance required given four parameters. Maximum ambient temperature maximum case temperature power output of your rf amplifier. Using the following specifications we can use our preferred formula to calculate the thermal resistance of both the s shaped heat sink and our generative heat sink. Input the cross sectional area m 2 add your materials thickness m enter the hot side temperature c enter the cold side temperature c click calculate solve for conduction heat transfer.

Heat source q 1500 w inlet temperature t in 293 k. Cross sectional area m 2. This heat sink calculator compares heat sinks using a solid metal base to those using a vapor chamber base. The total heat sink delta t is the sum of the following change in temperatures.
