Thermal Paste Conductivity Calculation

The parameters used to calculate thermal conductivity are the steady state temperatures the heat used for the warmer plate and the thickness of the material.

Thermal paste conductivity calculation.

A tube of 8 5w mk carbon based compound which is. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. I found in the manufacturers datasheet is has a thermal conductivity of 1 6w mk watt meter kelvin. Enter the thermal conductivity of your material w m k.

Carbon dioxide thermal conductivity online calculator figures and table showing thermal conductivity of carbon dioxide co 2 at temperatures ranging from 50 to 775 c 50 to 1400 f at atmospheric and higher pressure imperial and si units. I took 0 1mm as a wild guess. The heat transfer conduction calculator below is simple to use. It can be used for temperature ranges of 80 1500 k and for materials such as plastic glass and insulation samples.

I need to calculate thermal resistance of glue layer. Whilst all other data i have for the heatsink is in c w. For example the thermal conductivity of a high grade thermal paste is 8 5 w mk and the heat conductivity of copper is 385 w mk or for aluminum 205 w mk. How does the heat transfer conduction calculator works.

It is very accurate but takes a significant amount of time to. So rglue thickness area k k thermal conductivity. Price is normally set based upon thermal conductivity and the amount of compound in the tube generally in the range of 3g which is a few uses. You can see that the thermal compound is actually a poor heat conductor and that is exactly the reason why you only need a very thin layer of paste to fill the micro imperfections between.

The pcb thermal calculator helps you estimate the junction temperatures of components which use exposed pad packages. I my case area is 0 01m 0 009m 0 0000054 sq m k is 1 7 and i have no clue what thickness will be. Input the cross sectional area m 2 add your materials thickness m enter the hot side temperature c enter the cold side temperature c. But heat sink will be glued using thermal glue like hc910 which has thermal conductivity of 1 7 w m k.

This tool generates a quick estimate of the expected junction temperature based on the copper spreading area on the pcb. Or select a value from our material database. Thermal paste also called thermal compound thermal grease thermal interface material tim thermal gel heat paste heat sink compound heat sink paste or cpu grease is a thermally conductive but usually electrically insulating chemical compound which is commonly used as an interface between heat sinks and heat sources such as high power semiconductor devices.
