Auto Radiator Structure Is Also Constantly Adapt To The New Development
Jiangsu Guokai Autoparts Co.,Ltd | Updated: Oct 26, 2017

Radiator is a car cooling system, the engine water cooling system in the radiator from the water chamber, the water chamber, the main film and radiator core and other three parts.

The radiator cools up to a high temperature coolant. When the heatsink tube and the heat sink are exposed to the airflow generated by the cooling fan and the airflow generated by the vehicle movement, the coolant in the radiator cools.


There are two main types of radiator: aluminum and copper, the former for general passenger cars, the latter for large commercial vehicles.

Auto Radiator materials and manufacturing technology developed rapidly. Aluminum radiator with its light weight in the obvious advantages in the field of cars and light vehicles gradually replace the copper radiator at the same time, copper radiator manufacturing technology and technology has made great progress, copper brazing radiator in the bus, Engineering machinery, heavy trucks and other aspects of the engine radiator obvious advantages. Foreign car supporting the radiator for the aluminum radiator, mainly from the perspective of environmental protection to consider (especially Europe and the United States). In Europe, the proportion of aluminum radiators occupies an average of 64%. From China's auto radiator production development prospects, brazing production of aluminum radiator gradually increased. Brazing copper radiators are also used in buses, trucks and other engineering equipment.


Auto Radiator is an indispensable and important component in the cooling system of automotive water-cooled engines, and is moving in light, efficient and economical direction. Auto Radiator structure is also constantly adapt to the new development.

The most common form of Auto Radiator can be divided into two types of DC and cross flow.

Radiator core structure of the main form of tube and tube with two major categories. Segmental radiator core is composed of many fine cooling tube and heat sink, cooling pipe mostly use flat circular cross section to reduce air resistance, increase the heat transfer area.

Radiator core should have a sufficient flow area, so that coolant through, but also should have enough air flow area, so that sufficient air to take the coolant to the heat sink heat.

At the same time must also have enough heat dissipation area to complete the heat exchange between the coolant, air and heat sink.

Tubular radiator is made of corrugated heat dissipation and cooling tube.

Compared with the segment heatsink, the tube-type radiator under the same conditions, the heat dissipation area can be increased by about 12%, and the other on the radiating belt with a disturbing air flow similar to the blinds to break the flow of air in the heat On the adhesion layer, improve the cooling capacity.

Use and maintenance:

1, the radiator should not be in contact with any acid, alkali or other corrosive properties.

2, the proposed use of soft water, hard water to be softened after use, to avoid the internal heat block and scale generation.

3, in the use of antifreeze, in order to avoid corrosion of the radiator, be sure to use regular manufacturers and in line with national standards of long-term anti-rust antifreeze.

4, in the installation of radiator process, please do not damage the radiator (film) and bumps radiator to ensure the cooling capacity and sealing.

5, the radiator completely re-water and then water, the first engine block to open the water switch twist open, when the water out, and then closed, so as to avoid blisters.

6, in daily use should always check the water level, to stop cooling after the water. When the water is added, the tank cover is opened slowly. The operator's body should be kept away from the water inlet to prevent high pressure steam from being burned by the nozzle.

7, in the winter to prevent freezing caused by the phenomenon of core, such as long-term parking or indirect parking, the water tank cover and the water switch, the water will be released.

8, spare radiator effective environment should be kept ventilated, dry.

9, depending on the actual situation the user should be 1 to 3 months on the radiator for a complete cleaning of the core. When cleaning, rinse with water to the side.

10, the water level gauge should be cleaned every 3 months or depending on the actual situation, the parts removed with warm water plus non-corrosive detergent cleaning.
