The radiators are heat exchangers accustomed to transfer thermal energy from one medium to another for the aim of cooling and heating. A radiator may be a device consisting of an outsized amount of cooling surface which contains large amounts of air so it spreads through the water to chill efficiently.
There are two basic forms of radiator:
• Tubular type
• Cellular type
In a tubular type core, the upper and lower tanks are connected by a series of tubes through which water passes. Fins are placed round the tubes to enhance heat transfer. Air passes round the outside of the tubes, between the fins, absorbing heat from the water en passant. In a tubular radiator, because the water passes through all the tubes, if one tube becomes clogged, the cooling effect of the whole tube is lost. in an exceedingly cellular environment. radiator, the clogging of any passage leads to a loss but of a little a part of the whole cooling surface.
In a cellular type core, air passes through the tubes and therefore the water flows within the spaces between them. The core consists of an outsized number of individual air cells which are surrounded by water. Due to its appearance, the cellular type usually is thought of as a honeycomb radiator, especially when the cells ahead are hexagonal in form. In a cellular radiator, the clogging of any passage ends up in a loss but of a little a part of the overall cooling surface.
It consists of an upper tank and a lower tank and between them a core.
• The upper tank is connected to the water outlet or outlets from the engine jacket by a hose pipe
• The lower tank is connected to the jacket inlet through the pump.
• The core could be a radiating element, which cools the water.
The radiator may be a pretty simple device. Nowadays, the latest cars use aluminum radiators. Radiators usually have a tank on all sides, and inside the tank could be a transmission cooler.
