Introduction to radiators

A radiator is a heat-exchanging device that either absorbs or radiates heat. A typical radiator has a copper or aluminum tube bent several times to form a rectangle. These multiple loops help increase the internal surface area of the radiator and help in the cooling and heating process.

Radiator covers

Radiator covers serve several other purposes as well. They function as protective devices, shielding people from the extreme heat that can be generated. Radiators can pose severe burn hazards if left unattended. Some of the modern radiator covers can also double up as storage devices.

Automotive radiators

Automotive radiators have been instrumental in keeping the heat produced under control. These relatively simple devices have a complex function to perform under the hood of the car. In simple terms, a radiator is a device that dissipates heat through radiation.

All automotive radiators, whether in cars, trucks, buses and tractors, use the same principle while functioning. The liquid coolant that passes through the engine absorbs all the heat produced, keeping the engine temperature under control.

How a radiator works

Often, a radiator is made of a long copper or aluminum tube, bent several times to form a rectangular shape. Numerous small aluminum fins surround the tube. The aluminum draws heat from the warm cooling fluid inside the tube. Once the fins are heated, they release heat into the air, cooling the engine. The radiator has a neck that ends in a cap. The liquid coolant, usually a mixture of water and ethylene glycol, is added through this cap.

CONCLUSION

Each different type of radiator, whether automobile, building or electronic, has its own limitations and this should be kept in mind while using or servicing them. Proper care and maintenance of the radiator will ensure that the device works well.
