Selection Of Closed Cooling Tower

Influence of Heat Radiation on Type Selection of Closed Cooling Tower

There are three types of heat transfer: heat conduction, heat radiation, and heat convection. We have discussed the influence of heat conduction and heat convection on the selection of closed cooling towers. Heat conduction mainly determines the heat transfer material. Therefore, the cooling coils of closed cooling towers generally use copper or steel coils, and heat convection mainly Decide on the form of cooling, i.e. feng shui orientation, which design will allow the fastest heat convection. Next, let me tell you about the influence of heat radiation on the selection of closed cooling towers.

Thermal radiation refers to the phenomenon that an object radiates electromagnetic waves due to its temperature. One of 3 ways of heat transfer. All objects with a temperature higher than absolute zero can produce thermal radiation. The higher the temperature, the greater the total energy radiated, and the more short-wave components. The spectrum of thermal radiation is a continuum, and general thermal radiation is mainly transmitted by visible light and infrared rays with longer wavelengths. Since the propagation of electromagnetic waves does not require any medium, thermal radiation is the only way to transfer heat in a vacuum. When the temperature is low, it mainly radiates with invisible infrared light. When the temperature is 300°C, the strongest wavelength of thermal radiation is in the infrared region. When the temperature of the object is above 500°C to 800°C, the strongest wavelength component in the thermal radiation is in the visible light region.www.gwbrefrigeration.com
