  2. Computer fan control - Wikipedia

    en.wikipedia.org/wiki/Computer_fan_control

    The sense pin is used to relay the rotation speed of the fan and the control pin is an open-drain or open-collector output, which requires a pull-up to 5 V or 3.3 V in the fan. Unlike linear voltage regulation, where the fan voltage is proportional to the speed, the fan is driven with a constant supply voltage; the speed control is performed by ...

  3. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    To the right is a smaller heat sink cooling another integrated circuit of the motherboard. Typical heatsink-fan combination found on a consumer laptop. The heatpipes which contain a working fluid make direct contact with the CPU and GPU, conducting heat away from the component and transferring it to the fin-stack mounted on the exhaust port of ...

  5. Thermal management (electronics) - Wikipedia

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

    Peltier cooling plates / ˈ p ɛ l t i. eɪ / take advantage of the Peltier effect to create a heat flux between the junction of two different conductors of electricity by applying an electric current. [9] This effect is commonly used for cooling electronic components and small instruments.

  6. 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.

  7. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

  9. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
