Description
The auto radiator has two key parts: heat sink composed of small flat tube, andoverflow tank (on the top, bottom or both sides of the radiator). If theautomobile has a service time five years or above five years, the coolingsystem maybe has some problems. The automobile has been exposed to environmentswith salinity, fragment and other chemical materials which do harm to thecooling system for a long time, the metal parts of the auto radiator have beendestroyed, the engine maybe overheated, and the cylinder maybe exploded. In thatcase, you need a new auto radiator.

Principle
When the engine is in the cold clean criticality or the low temperature, theroute of engine coolant is a minor cycle. In that case, the coolant does notflow through the auto radiator. When the coolant temperature arrives in acertain value, the coolant is in a big circulation. It may reduce the time ofengine's temperature rising, the energy loss and the metal parts’ attritioneffectively. The cooling circulation route is controlled by thermostat which isin the lower part of water pump. When the engine coolant temperature arrives to- 358K (85°C),thermostat valve is open, the engine coolant starts to flow through the autoradiator in a big circulation. When the engine coolant temperature arrives to378K (105°C), thethermostat valve is open completely, the engine coolant circulation andradiation are strengthened, the engine coolant’s temperature rising is alsocontrolled. The principle of an auto radiator is to use cool air to reduce thetemperature of engine coolant

Function
When you start the automobile, the overheating ofengine destroys the automobile. Therefore, there should be a cooling systeminstalled on the automobile to maintain the engine in a suitable temperaturerange. Auto radiator is the main part of a cooling system. It is designed toprotect the engine from destruction caused by overheating. An auto radiator isused to reduce the temperature of engine coolant by cooling air.
