2. Automobile auxiliary power outlet - Wikipedia

   en.wikipedia.org/wiki/Automobile_auxiliary_power...

   For the 12 volt systems, the center contact is the positive terminal and the shell is the negative terminal. Most automobiles connect the negative terminal to the frame of the vehicle (negative ground). 12 volt auto connectors are made to comply with a standard by Underwriters Laboratories for safety. UL2089 was developed to cover the ...

3. Internal fan-cooled electric motor - Wikipedia

   en.wikipedia.org/wiki/Internal_fan-cooled...

   An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor.Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.

4. TEFC motor - Wikipedia

   en.wikipedia.org/wiki/TEFC_motor

   TEFC enclosed motors usually cost more than open motors, but offer increased protection against weather, dirt, and moisture. TEFC motors are constructed with a small fan on the rear shaft of the motor, covered by a housing. This fan forces air over the motor frame fins, and cools the motor. The enclosure is "Totally Enclosed". This means that ...

5. Computer fan - Wikipedia

   en.wikipedia.org/wiki/Computer_fan

   Larger fans are usually used for cooling case, CPUs with large heatsink and ATX power supply. Square 80 mm and 92 mm fans are used in less demanding applications, or where larger fans would not be compatible. Smaller fans are usually used for cooling CPUs with small heatsink, SFX power supply, graphics cards, northbridges, etc.

6. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

7. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   An axial box fan for cooling electrical equipment. Axial-flow fans have blades that force air to move parallel to the shaft about which the blades rotate. This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in cooling towers. Axial flow fans are applied in air ...

8. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   [15] Electric fans, lamps, alarms, coffee warmers, battery chargers, and even toys have been designed to tap power from a USB connector. Plug-in adapters equipped with USB receptacles are widely available to convert 120 VAC or 240 VAC power or 12 VDC automotive power to 5 VDC USB power (see photo at right).

9. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   The +12 V supply was used for computer fan motors, disk drive motors and serial interfaces (which also used the −12 V supply). A further use of the 12 V came with the sound cards, using linear chip audio power amplifiers, sometimes filtered by a 9 V linear regulator on the card to cut the noise of the motors.
