Why Do Car Accessories Sell As Hot Cakes?...
An automobile isn't just a means of transport, it's also a possession, a convenience, a fashion statement....


 Automobile Cooling System    Industry
Automobile cooling parts manufacturing industry is growing at a rate of 4.3 percent annually, which is soon predicted to reach to US $ 9.1 billion by the end of year 2010. This industry is experiencing boom because of new innovations, technologies and introduction of stringent emission regulations. China, Czech Republic, Hungry, India, Brazil, Iran, Mexico, Thailand and Turkey are the emerging markets of engine cooling systems and their parts.

Automobile Cooling System
The cooling system forms an intrinsic part of an automobile engine. It performs multitude of functions such as removing excess heat from the engine, maintaining efficient temperature and allowing engine to perform its task within a short span of time. Ideally, automobile cooling system keeps the engine running at an optimum temperature whatever the operating conditions are. Automobile Cooling System consists of components or equipment installed in vehicles for removing heat from all the moving parts so that they can work suitably without melting, seizing and overheating. More specifically, automotive cooling system makes use of coolant, lubricating oil and fan to maintain and regulate the temperature of other parts of an engine. Basically, there are two types of automobile cooling systems, which are widely used by the automobiles namely: liquid cooling and air-cooling. Liquid cooling is one of the sought after system used by most of the vehicles today while air-cooling is mostly used by airplanes, motorcycles and lawn mowers. The liquid-cooling system for automobiles offers the most positive cooling and it maintains an optimum engine temperature. While air cooling system is feasible for only small vehicles and equipment, as air-cooled engines do not operate at consistent temperature and command extensive use of aluminum to disperse heat.

Working of an Automobile Cooling System 



Figure illustrated above describes the functioning of cooling system of an automobile. The key components used in a cooling system are pressure cap, heater hoses, thermostat, heater core, reserve tank, lower hose, transmission cooler, water pump, fan, radiator and upper house. The cooling system of a vehicle operates or functions by directing liquid coolant via passages in the engine block and heads. After that the liquid coolant which flows through passages absorb the heat from an engine. Then this fluid passes through a rubber hose to reach to the radiator. At this stage the hot liquid is cooled by air stream entering the engine compartment via grills. Once it gets cooled, then it goes back to engine and same process repeats again.

Engine Cooling Fluids are the liquids or gases which are passed through an internal combustion engine with the key function of regulating temperature, stopping overheating and maintaining operating clearances. These are mainly used for cooling the heated fluid within a thermal system or a machine.
Different types of engine cooling fluids available in the market are:

Engine Cooling Fluids
Water Cooling Systems
Water Cooling Systems includes various components, equipment and accessories that are explicitly used for cooling internal combustion engines in automobiles. An automobile engine cooling system basically need water and other anti freeze mixtures to lower down the shooting temperature of the engine.
Water Cooling System constitute of various parts which are mentioned below:

Valves are the mechanical devices, equipment or accessories, which are inserted into the engine of a vehicle for directing and controlling the flow of a liquid or gases within an engine. In simpler terms, valves and its different parts monitor the entry as well as the exit of air and fuel mixture into a combustion chamber of the engine.
Valves used in automobile engine can be classified into following categories:

Valves
A/C Parts
A/C Parts consists of whole ensemble of mechanical components or apparatus used for controlling and lowering the temperature and humidity within an enclosed space. In other words, air conditioning parts are those, which are used for cooling and dehumidifying impure air entering the passenger compartment of a vehicle. The air conditioning system of a vehicle makes use of refrigerant for cooling the air and taking away the heat from the passenger compartment.
Major components of automobile air conditioning systems are:

Cooling System Gaskets are seals or packing especially designed for joining or sealing the matched components or pipe joints in an automobile cooling system with the main purpose of stopping the escape of a gas or liquid. Usually, cooling system gaskets are made up of soft sheet metal, which are stamped with ridges that enclose all leak points. Even steel, copper and asbestos can also be used for making cooling system gaskets. The main function of cooling system gaskets is to prevent fluid or gas leaks by offering a close or tight barrier between two mating surfaces.
Types of cooling system gaskets are:

Cooling System Gaskets
Aluminum Housing
Aluminum Housing As its name suggest, aluminum housing are the protective coverings or fully enclosed cases made of aluminum metal for containing or supporting mechanical components of a vehicle. In other words, housings are basically frames, brackets or boxes of varied sizes designed to hold or protect a mechanical part of a vehicle.
