Automobile Brazed Radiator materials and manufacturing technology are developing rapidly
There are two main kinds of automobile Brazed Radiators: aluminum and copper, the former for general passenger cars and the latter for large commercial vehicles. Automobile Brazed Radiator materials and manufacturing technology are developing rapidly. Aluminum Brazed Radiator with its obvious advantages in lightweight materials, in the field of car and light vehicle gradually replace copper Brazed Radiator at the same time, the copper Brazed Radiator manufacturing technique and technology has made considerable development, copper brazing Brazed Radiator such as buses, engineering machinery, heavy truck engine Brazed Radiator has obvious advantages. The Brazed Radiators of foreign cars are mostly aluminum Brazed Radiators, which are mainly concerned with environmental protection (especially in Europe and the United States). In the new European car, the proportion of aluminum Brazed Radiator is 64%. From the development prospect of the production of the Brazed Radiators in China, the Brazed Radiators of brazing brazing are gradually increasing. Brazing Brazed Radiators are also used in buses, truck and other engineering equipment.
Engine Brazed Radiator hose use for a long time will be aging, easy to burst and water is easy to enter the Brazed Radiator, hose burst in the process of driving, spitting out the hot water will form a large mass of water vapor from under the hood, this phenomenon occurs, should immediately select safe parking places, and take emergency measures to solve. Under normal circumstances, the Brazed Radiator, the water hose of the most easy to produce cracks and joint leaks, then you can use scissors to cut off the damaged parts, and then put the hose to Brazed Radiator inlet on the joint, with clip or wire clamping. If the gap in the middle of hose, seizing leaking fissure can use tape before seizing hose will wipe up, wait for leaking place after drying, the tape winding hose leaks, due to engine working when the tube and the water pressure is higher, so to try to tape wrapped tightly. If you don't have the tape at hand, you can wrap the plastic wrap around the crack, then cut the old cloth into strips and wrap them around the hose. Sometimes the hoses are large and can still leak when they are wrapped, so the cap can be opened to reduce the pressure in the channel and reduce the leakage. After the above measures, engine speed cannot too fast, try to hang a high-grade road, the road to pay attention to the cursor position water thermometer, found that the water temperature is too high to stop cooling or cooling water.
The note related to the use of Brazed Radiator: see the shape of the shape fin Brazed Radiator through a thin aluminum plate, which looks like the bellows of the accordion. Each cooling blade of the eddy soldering radiator incline in one direction to help the air flow. The two products have better heat dissipation efficiency. The price of Brazed Radiator of material aluminum extrusion profile is the lowest, but the heat dissipation is not good. Gold, silver and copper Brazed Radiators have good heat dissipation, but they are expensive and heavy. The most cost-effective is the Brazed Radiator of aluminum alloy. See area Brazed Radiator is through the form of convection to heat emission, the surface area is bigger, the heat dissipation effect is better. When choosing Brazed Radiator, it should pay attention to the heat sink area of Brazed Radiator. Other: when choosing the Brazed Radiator of aluminum products, it should also be noted that the bottom of Brazed Radiator should not be too thick, because the thermal conductivity of aluminum is not good, so thick will affect the transfer of heat. In addition, the guide groove of the Brazed Radiator surface should be dense, so that the soldering radiator can have a larger contact area with the air, thus enhancing the cooling effect. Do not recommend buying silent passive laptop Brazed Radiator, because at the bottom of the notebook computer design and Brazed Radiator support contact area is very small, it is difficult to heat conduction from the fuselage on Brazed Radiator.
