Vehicles are driven by the thermal power generated from the fuel combustion inside the engine cylinder with a working temperature of more than 2000℃. Without timely cooling, the engine components will expand in response to overheating, resulting in unacceptable and even dangerous levels of expansion that would eventually lead to engine damages. To prevent the engine from overheating, a cooling system must be installed to cool those components located around the combustion chamber, including the cylinder head, cylinder block, cylinder valve and other components.
The cooling of the engines is usually one of these two types: liquid-cooled and air-cooled. Traditionally, the liquid-cooled systems are comprised of the radiator, thermostat, water pump, passages inside the engine block and heads, and radiator cooling fans. The cooling systems work with a heat transfer process of the inside liquid to the outside air. The liquid coolant is circulated by the water pump to flow through the engine, carrying the heat generated by the combustion in the cylinders, then cooled by the air flow through the radiator. While the coolant flows through the aluminum tubes of the radiator core, the heat is transferred to exterior air with the aid of the fins or flakes and carried away from the engine. The radiator is usually comprised of the aluminum radiator core and plastic header tanks.
The radiator is an essential element of the liquid-cooled system for an internal combustion engine. With the development trend towards a lighter structure, higher efficiency and better cost effectiveness, the automobile radiator features a new, innovative structure designed to meet new technologies and requirements.
The tube-flake radiator core uses thin flattened tubes fitting through the flakes. The tubes are designed with a flattened round cross-section to reduce air resistance and increase the heat exchange surface. The radiator core features a sufficient flow area for liquid coolant and air stream and a large enough heat dissipation area for rapid transfer of heat from the coolant to the air.
The tube-fin radiator is welded by corrugated fins alternatively with cooling tubes. Compared to a traditional tube-flake radiator, this type of radiator features an increase of 12% in the heat radiating area. In addition to that, louver-like holes on the corrugated fins can help enhance the cooling efficiency.
