2. Thermal management (electronics) - Wikipedia

   en.wikipedia.org/wiki/Thermal_management...

   Online heat sink calculators from companies such as Novel Concepts, Inc. and at www.heatsinkcalculator.com [7] can accurately estimate forced and natural convection heat sink performance. For more complex heat sink geometries, or heat sinks with multiple materials or multiple fluids, computation fluid dynamics (CFD) analysis is recommended (see ...

3. Logarithmic mean temperature difference - Wikipedia

   en.wikipedia.org/wiki/Logarithmic_mean...

   In a cross-flow, in which one system, usually the heat sink, has the same nominal temperature at all points on the heat transfer surface, a similar relation between exchanged heat and LMTD holds, but with a correction factor. A correction factor is also required for other more complex geometries, such as a shell and tube exchanger with baffles.

4. Cooling load temperature difference calculation method

   en.wikipedia.org/wiki/Cooling_load_temperature...

   The data is divided into many different sections based on many different variables. These variables include, building material of the envelope, thicknesses of the building materials, day of the year, time of day, orientation of the surface (e.g. wall or roof, 90 degrees or 180), and wall face orientation (cardinal directions, i.e. N, NW, S, SE ...

5. Heat transfer coefficient - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_coefficient

   There are also online calculators available specifically for Heat-transfer fluid applications. Experimental assessment of the heat transfer coefficient poses some challenges especially when small fluxes are to be measured (e.g. < 0.2 W/cm 2). [1] [2]

6. Heat sink - Wikipedia

   en.wikipedia.org/wiki/Heat_sink

   The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:

7. Thermal conductance and resistance - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductance_and...

   is the absolute thermal resistance of the heat sink. The heat flow can be modelled by analogy to an electrical circuit where heat flow is represented by current, temperatures are represented by voltages, heat sources are represented by constant current sources, absolute thermal resistances are represented by resistors and thermal capacitances ...

8. Thermal mass - Wikipedia

   en.wikipedia.org/wiki/Thermal_mass

   The equation relating thermal energy to thermal mass is: = where Q is the thermal energy transferred, C th is the thermal mass of the body, and ΔT is the change in temperature.

9. Fin (extended surface) - Wikipedia

   en.wikipedia.org/wiki/Fin_(extended_surface)

   Sometimes it is not feasible or economical to change the first two options. Thus, adding a fin to an object, increases the surface area and can sometimes be an economical solution to heat transfer problems. One-piece finned heat sinks are produced by extrusion, casting, skiving, or milling.
