Car radiator fins are thin, metallic components that increase the surface area of the radiator, allowing for air to pass through and playing a crucial role in the efficient cooling of the engine.
As in a car radiator, the air passes through the tube in crossflow. This supports cooling the liquid inside, and the advantage of fins over ordinary tubes is that they provide more significant contact with the liquid outside. Also, this allows for quicker heat exchange between the inside and outside of the tube.
Radiator fin: the quality of the fin we can judage from the below points: 1. the fin thickness 2. the fin height and 3. the fin pitch and 4. the fin louvers number and angle. Firstly the thickness of the fin can influence the radiating performance, the thicker the better, for passenger cars usually we use thickness at 0.8mm and 1.0 mm for heavy duty trucks, while the other factories might to use 0.7 for passenger cars and 0.8 for truck radiator. Second the fin height: At most situation, less distance between tubes will make the heat radiating more efficiently, e.g., fin height at 8mm will be better than fin height 9mm; fin height at 5mm will be better than fin height 8mm. On the other side, radiator with 9mm fins will save material than 8mm, and the material cost is reduced. Third the fin pitch: the smaller the pitch is, the performance will be better as there are more heat can be transfered from the fins, usually most of the factory make the fin pitch at 3.0 mm, VALSENS makes all fin pitch at 2.7-2.8mm, while the OE products usually make at 2.5-2.6mm for most of the radiators. At last the fin louve number and angle: usually more number of louvers will have better heat transfermation ability and a good angle of the louver designed is also very importand to make the heat away from the radiators, VALSENS ' fin are designed to have the most louvers as it could be as well as the louver angle at the most scientific positions.
Aluminum Flat Oval Welded Tube For Radiators (Radiator Tube)A flat oval welded tube is mainly used as a radiator tube, the radiator is the most important component of the cooling module, which consists of the radiator core and plastic tanks with all requisite connections and fastening elements.
Radiator Tube: Usually, Aluminum radiator use HF tube. (High frequency welded tube). This tube material includes 3 layers: 4343/3003/7072. The inside 7072 layer is very important to prevent the corrosion from the chemicals in the water coolant inside the radiator. There is another kind of tube--extrude tube. This tube doesn’t have 4343 outside layer to help the tube and fins to be brazed during production, and there is none 7072 inside to help anti-corrosion, but it's cheap. We found another problem from extrude tube are the hardness. It's weakly than the HF tube due to the process for the extrude tube. Valsens use all HF tubes with material 4343/3003/7072 to ensure the good quality.
Header and side plate: for radiator use big tanks, the header-plate will bear more pressure. Then, the thickness of the header-plate became very important. Normal 1.5mm thickness is not enough. The designer must notice this. Valsens use 1.5 mm thickness for most of the header and plate and 1.8mm for these radiators with big tank and 2.0mm for bigger engine cars.
Your radiator’s job in your vehicle is simply to keep the engine from overheating. The radiator is a vital component of the cooling system of your vehicle. When your car radiator is not working properly, there are many different signs that you will notice. If you are not familiar with these or are not sure, here are three main symptoms of a failing radiator
1. Vehicle is overheatingIf your car temperature gauge indicates the temperature is way too high or your check engine light illuminates on the dash, your car is most likely overheating. This could be due to a bad or failing radiator. It may not be completely failing but close to that condition. So you want to make sure to address the situation right away! If this is not repaired immediately, your car may break down because of your overheated engine and the radiator cost repair will be higher. If you’re not sure if your car is overheating, play it safe and visit your local automotive repair shop right away! Better safe than sorry.
2. Leaking coolantIf you find that your vehicle is leaking a lot while you’re driving or when it’s parked, it could be from coolant from your bad radiator. You may be able to identify where it is leaking from. If not, take it in and see the professionals to find out how much the radiator cost repair will be. Find a local automotive repair shop or mechanic that can give you professional advice on how to best handle this repair
3. Sludge in your vehicle’s radiatorSludge in your radiator is a sign that your radiator is in need of repair. A bad mix of coolants can cause this sludge in your radiator and cause lots of problems. A bad head gasket can cause oil and coolant to mix and form sludge as well. Visit your local automotive to find out what your radiator cost repair will be and to see why this sludge may be forming in your vehicle.
4. Get a radiator flush!We at Majestic Auto parts recommend getting a radiator flush about every 40 to 60 thousand miles you drive! But some people do a radiator flush every year to play it safe. It’s totally up to you! Check your vehicle’s owner’s manual to find the best advice for your specific vehicle.
5. So, what is a radiator flush?A radiator flush will flush out all of the contaminants in your cooling system that could be affecting your vehicle.
