2. Thermal management (electronics) - Wikipedia

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

   CPU heat sink with fan attached A heat sink (aluminium) incorporating a heat pipe (copper) All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. [1]

3. Computer fan control - Wikipedia

   en.wikipedia.org/wiki/Computer_fan_control

   Full-tower computer cases may contain multiple cooling fans. At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they ...

4. Auto-defrost - Wikipedia

   en.wikipedia.org/wiki/Auto-defrost

   A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.

5. Computer cooling - Wikipedia

   A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan. Vertical aluminium ...

6. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

7. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.

8. Pulse tube refrigerator - Wikipedia

   en.wikipedia.org/wiki/Pulse_tube_refrigerator

   Figure 1: Schematic drawing of a Stirling-type single-orifice PTR. From left to right: a compressor, a heat exchanger (X 1), a regenerator, a heat exchanger (X 2), a tube (often called the pulse tube), a heat exchanger (X 3), a flow resistance (orifice), and a buffer volume. The cooling is generated at the low temperature T L. Room temperature ...

9. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...
