The most notable fan used for both heating and cooling would probably be of the Dyson brand. They have a product called the Dyson Hot+Cold, which is a bladeless heater fan used for both cooling and heating.

∙ 10y agoFan is the thing that makes air to the cooling metal things, the ones that carrys the water. Exhaust is the thing it puts out all the noise.
If the question is about the motor fan or engine fan, the main function of this fan is cooling the radiator of the engine which in turn is cooling the water circulating inside the engine unto the radiator and back. This keeps the engine at a fairly operable temperature without overheating and damaging damaging its parts.
The first cooling fan was invented in 1882. It was invented by Schuyler Skaats Wheeler. The ceiling fan was invented in 1887 by Philip Diehl.
heat sensor with fan cooling it will be used for cpu . it will be cool thing the mother board it will be reduce cpu temperature.........
Some motors are specially designed for low speed. Some are "invertor Duty" classified so that they can be run on invertor (VFD) normally with a high heat dissipating design. On low speed the cooling effect reduces drastically since the cooling fan is mounted on the same motor shaft. Hence a separate small cooling fan is mounted on the motor, driven by separate power such that it keeps running at normal speed irrespective of main motor speed, thus providing the required cooling effect.
A ceiling fan should blow downwards when used with cooling, upward when used with heating.
It is the relay for the heating and cooling fan
Have you checked the coolant levels or the cooling fan?
You may have a bad or weak cooling fan sensor.
That is the fan cooling the liquid in the radiator to keep the engine from over heating.
It's quite literally a combined heat sink and fan. It's used to help keep a CPU -- Central Processing Unit -- from over heating.
Computer cooling fan
An advantage of the Targus cooling fan is that you can remove the chill hub to make it easier to carry while traveling.
indoor fan relay An electric relay that starts and stops an indoor fan on cooling, electric - heating, and heat pump systems
1. The possibility that the setting switch is for blower/ fan or for heating and not cooling in air conditioners that have both heating/cooling system.. 2.The chilling compartment /compression of cooling gas has leaked. 3.The compression is weak to chill the cooling compartment.
While your car is running the engine is heating up. While your driving you have air being forced over the radiator cooling it off. When you are sitting still you don't have that air so your engine is heating up even more so the cooling fan comes on to help cool you engine off. Via cooling the radiator.
Sounds like a bad switch or solenoid.
