The common measure of the ability of a metal to conduct heat is its Thermal conductivity is defined as:-
“The quantity of heat transmitted through a unit thickness of a material – in a direction normal to a surface of unit area – due to a unit temperature gradient under steady state conditions”.
Equation for the rate of thermal conduction:
Q/t= kAΔT/d
Q => The amount of heat transferred in a time t
K => Thermal conductivity constant for the material
A => Cross sectional area of the material transferring heat
D => thickness of the material
ΔT => Difference in temperature between one side of the material and the other
Thermal conductivity for common materials and products:
The high rate of thermal conduction in copper and some of its alloys makes it a favorite among various industrial and commercial applications. To know more about it visit supermetalind.com.
APPLICATIONS:
- Copper is a popular choice for heat exchangers. Heat exchangers do their job by transferring heat to achieve heating or cooling. Copper is used in
- industrial facilities,
- air conditioning,
- refrigeration,
- hot water tanks
- under-floor heating systems.
- solar thermal water systems
- Water heaters
- Furnaces boilers and stoves
Copper allows heat to pass through it quickly. Also because of its corrosion resistance and thermal expansion, copper is favored over other metals like aluminum which are cost effective.
- Used in CPUs and graphics processors to absorb heat generated by the system
- Copper is used a heat sink material in power transistors and LEDs
- Copper is used in kitchenware and cookware
