As the name suggests, the role of the radiator is to dissipate heat. How does it work? How does a radiator work? Today is explained by Yuanyang Thermal factory.

 

How does a radiator work

 

At present, there are four main heating systems for radiators in life: hydrothermal radiators, electric heating radiators, steam heating radiators, and superconducting radiators. The principle of the heat sink is heat conduction. For example, iron, aluminum, copper and other good thermal conductivity are used as heat sinks, and the heat sinks cover the chips. It is equivalent to increasing the contact area between the chip and the air. Can better heat dissipation, radiator, air cooling, water (oil) cooling, other advanced heat dissipation. But civilians are basically air-cooled.

 

1. Use a water temperature radiator, wall-mounted or boiler to heat the circulating water, connect it to the radiator through pipes, and finally output an appropriate temperature through the radiator to form an indoor temperature difference, and the entire indoor temperature rises evenly through thermal circulation.

 

2. Superconducting radiator, walk in the steel pipe of the middle layer at the bottom of the radiator, inject a small amount of superconducting liquid into the inner cavity of the radiator, the superconducting liquid in the vacuum part of the superconducting radiator is activated, and the evaporated high-temperature gas passes through the surface of the radiator to the surface. dissipate heat.

 

3. Steam heating radiator, heating equipment (boiler) in the water treatment equipment to heat and evaporate, and use the evaporated water vapor to heat the room through the radiator. The water vapor transfers heat to the radiator by convection through the radiator, the radiator transfers heat from the inner wall to the outer wall by its own heat, the outer wall heats the air in the space by convection, and the walls (walls, furniture, etc.) contained in the space are heated by radiation , raise the temperature of the room to a certain temperature.

 

4. The electric heating radiator is a purely resistive electrical appliance. The current passes through the resistance wire to heat the resistance wire and convert electricity into heat.
