car radiator myth busters: the facts about vehicle cooling systems - aluminum heat dissipation
Since automakers began using radiators with plastic cans, myths about radiators have begun to circulate.
By providing facts, this article dispels some of the more popular myths circulating on the Internet.
Myth 1: slow down or slow down the engine when overheating. This is a bad suggestion.
Engine cooling is a combination of coolant flow and radiator air flow.
Sometimes the best thing you can do is increase the speed or engine speed to provide more coolant flow, more airflow, or both.
I remember on a coast. to-
Drive through the coast of Arizona at a temperature of 120 degrees.
My Porsche 944 Turbo had a hard time keeping it at 65 mph, so I increased the speed to 80 to a normal operating temperature.
Another trick you can use if your vehicle is overheating is to turn on the heater.
This is feasible because the heater is basically a cooling coil that dumping heat from the engine inside the cabin of the vehicle.
You will not be comfortable if it is hot outside, but you will save the engine.
Myth 2: insects will ruin your radio and while this may be true, the situation must be very extreme.
We are talking about driving through a group of locusts at a very high speed. Not likely.
This is the case.
In areas with a large number of insects, your car, truck or SUV radiator will collect insect remains.
The hot cooling coil dehydrate quickly until the only thing left is the wings and the outer bones.
It is easy to wash away the remains with a hard good water.
As long as you keep the car clean, you have nothing to worry about when it comes to worms.
Myth 3: The small coolant drops on the garage floor are not big DealA, a little bit of ethylene glycol may not seem like a big deal, but it does.
First, dumping ethylene glycol and other harmful substances into surface water is a violation of state and federal laws.
This is exactly what you are going to do when you park your car on the street.
The rain washes the coolant into the rain drain and then pours into the surface water.
It is very toxic.
Both dogs and children find it irresistible and sweet.
So get it out of your car. -
In one way or another-
The secret of disaster.
In addition to health and environmental hazards, car radiator leakage will become a cooling system failure sooner or later.
If it leaks on the radiator, it will eventually open its mouth and discharge all the coolant.
If it is a hose, the hose will blow out and fail.
If it is sealed, you will introduce air into the system, which may cause the steam lock to prevent proper cooling.
In other words, all sorts of annoying things can happen, which will cost you more time and money than solving problems when they are small.
Myth 4: All against
Frozen products are almost SameI hoping the myth is true, but this is not the case.
In fact, some car manufacturers, such as Porsche, will cancel the car warranty if you do not use the specified liquid.
Be sure to check your owner's guide before you pour any old product into the cooling system.
Like your oil, this is a fluid that is critical and requires the right specification.
Myth 5: If you are building a very high-performance car or a racing car, then the all-aluminum radiator is possible.
Aluminum is very light and weight loss is important when your goal is moving fast.
That is to say, aluminum is not the best thermal conductor.
Copper is much better, for example.
In fact, a number of factors have been taken into account by car manufacturers, including weight, size, heat dissipation quality, cost and durability.
If you replace the defective device, then your best choice will always be the original device (OE)
Or OE specifications.
If you are building a high-performance car, custom radiators should be considered.
