WebNov 12, 2013 · How to calculate the heat dissipation in BTU per hour. Product Line: All Schneider product lines. Cause: The calculation to determine the BTU for adding a piece of equipment to a cabinet to prevent overheating. Resolution: To calculate heat dissipation, multiply watts by 3.4192. The result will be expressed as 1 kW is equal to BTU / HR. WebTo use this enclosure heat calculator quantify the amount of heat from components in Watts. With total heat calculated, the calculator determines the expected temperature rise based on the control panel size and type. If required, engineers may elect to discharge heat via venting or air conditioning.
Webadded to aluminum or copper heat sinks to ease spreading resistance. 2.2.2 Shape - Heat transfer takes place at the surface of the heat sink. Therefore, heat sinks should be considered to have a large surface area. This goal can be reached by using a large number of fine fins or by increasing the size of the heat sink itself.
