The core of the tubular radiator is composed of many thin cooling tubes and heat sinks, and the cooling tubes mostly adopt flat and circular sections to reduce the air resistance and increase the heat transfer area.The core of the radiator should have a sufficient flow area for the coolant to pass through, and it should also have a sufficient air flow area for a sufficient amount of air to pass through to take away the heat transferred by the coolant to the radiator. At the same time, it must also have sufficient heat dissipation area to complete the heat exchange between the coolant, air and heat sink.The tubular belt radiator is composed of corrugated heat distribution and cooling pipe interarranged by welding.Compared with the tubular radiator, the tubular radiator can increase the heat dissipation area by about 12% under the same conditions, and the heat dissipation belt is opened with a similar window shutter hole with disturbed air flow to destroy the adhesion layer of the flowing air on the surface of the dispersion zone and improve the heat dissipation capacity.
