Transfer of heat within thermally conductive body or between thermally contacted bodies due to temperature difference is known as * Conductive Heat Transfer.* You can use conductive heat transfer calculator to calculate conductive heat transfer in solid bodies. For more details, Read this article on Conduction Heat Transfer.

## Conductive heat Transfer Formula

**Conductive Heat transfer (Qc) = – K A dT/L**

Where

Qc = Conductive heat transfer per unit time in watt

A = cross section area in square meter

k = Material Thermal Conductivity (W/mK)

dT = Temperature Differential

L = Thickness/Length of the part in Meter

## Conductive Heat Transfer Calculator

## Conductive Heat Transfer Problem Example

**Question:** Consider an copper flat plate of size 200 x 200 mm and thickness 100 mm. Temperature of the plate near heat source is 50 ºC. Whereas as cooler side its 20 ºC. Thermal Conductivity of copper is 385 W/mK. Calculate the conductive heat Transfer?

**Answer:** This is the example of real life problems that engineers face during product Design. This Problem can be solved by using a convection calculator or manually.

Temperature Difference = 50 – 20 = 30 ºC

Conductive Heat transfer Coefficient for Copper = 385 W/mK

Surface Area = 200 x 200 = 40000 mm² = 0.04 m²

**Convective Heat Transfer = (385 x 0.04 x 30) / (0.1) = 4620 watt**
