An internally threaded tube means that one or more spiraling rifling lines are machined into the inner wall of the tube, which are rectangular grooves when viewed from the cross-section. Internal threaded tube is also called dry evaporator tube, internal ribbed tube or internal finned tube. In central air conditioning units it is mainly used on dry evaporators. It is also used in domestic and commercial air conditioning heat exchangers or for high heat pipes. The internal surface area per unit length of internal ribbed tube is 1.5~2 times that of ordinary glossy copper tube, and its heat transfer coefficient is 1.5~2.4 times that of glossy copper tube of the same specification. And the carrier flow resistance increases only 3-5%, which can save energy by 20-35%, and the weight of the whole machine of suitable refrigeration air-conditioner is reduced by 10-25%.
The product has thin wall, high teeth, low teeth, fine teeth, small teeth and other different tooth shape, can be customized according to the use needs.
The product material has 3003 anti-corrosion aluminum alloy and our unique high efficiency anti-corrosion of aluminum alloy, the product anti-corrosion effect is better than 3003 aluminum alloy 10 times. Two materials are selected from.
The thread aluminum tube can strengthen the heat transfer in the evaporator- -increase the heat transfer area, increase the number of gasification core, and increase the turbulence degree of the liquid film
Threaded aluminum tube in condenser-increase the heat transfer area in the tube. Under the action of surface tension, the condensant is forced to leave the heat transfer surface. It reduces the thickness of the refrigerant liquid film between the tooth top and the tank agent.
