Definition of
Radiator
A radiator it’s a exchanger heat. It is an element that allows dissipate heat from somethingeither to prevent it from overheating or to take advantage of it in heating a place.

radiation and convection
Radiators can work for radiation and by convection. What these devices do is receive or release heat, depending on their function and the difference in temperature between the exchange media.
In the internal combustion engines used by automobiles and other machines, the radiator is used to remove heat from coolantgiving it to air. Its operation is very important since, while they are on, these motors produce a lot of heat that is essential to dissipate.
The radiator, in this framework, is part of the circuit liquid cooling vehicle. In order to enhance the effect of convection, a fan with thermostat and equipped with a small motor favors air circulation through the device.

on electronic devices
The computers (computers), on the other hand, have radiators attached to fans to dissipate the heat that is generated in the circuits, thus avoiding damage to the electronic components. These radiators, known as heat sinksmake it possible to cool microprocessors, especially the CPU and GPU.
To this day, this also occurs in other devices, beyond computers. For example, in video game consoles. Basically, any device that requires at least one microprocessor for its operation and that, for reasons related to its design and its application generates too much heat to dissipate it in any other way, requires the installation of a radiator.
Interestingly, today’s most popular devices, mobile phones, do not take advantage of this technique to dissipate heat, as they are too narrow. How do manufacturers of phones, tablets and other ultra-thin devices prevent their processors from burning out? They usually take advantage of their own Case metal to act for this purpose. In fact, one of the reasons they don’t generate as much heat as a desktop computer is that they use much less electrical power.

Finally, as a heating device, the radiator is a device that contemplates the circulation of a hot liquid inside for radiate heat to the environment. It may have tubes, fins, or panels to emit such heat. In general, this resource is used in the development of a system central heating.
In this context, one speaks of heat transfer fluid, the liquid that transports heat from one point to another, passing through different channels. The process is relatively simple, although it must be repeated many times throughout the operation: the fluent it heats up at one point and then moves to give it up at another. There are different types of radiators, such as steel tubeswhich are usually arranged vertically and welded to two collectors, one above and one below.
Steel tube radiators effectively resist pressure and are used in industrial environments, at high altitudes and where there is steam in the environment. We also have the finned tubular radiators, which have a larger emission surface. These fins are placed on the tubes and thanks to this design it is possible to manufacture smaller radiators, although cleaning becomes more difficult, since it has more recesses than the previous one.
Another common type of radiator is flat panelswhich consists of two sheets steel with a maximum thickness of 4 millimeters, smooth or channel-shaped. It is the cheapest on the market.
