Efficient anti-scaling condensation pipe

Abstract

The invention relates to an efficient anti-scaling condensation pipe. A thin-wall circular pipe is made of stainless steel, straight pipes with equal diameter are at two ends, a corrugated pipe is on the middle part, and the outer surface of the corrugated pipe is evenly distributed with raised pyramid lug bosses. The condensation pipe has the following advantages that: because fluid in the corrugated pipe disturbs intensively at low flow rate to generate turbulent flow which has complete flushing function on the pipe wall, the easy-scaling problem of the condensation pipe is well solved; simultaneously, due to surface curvature change and axial extension change of the corrugated pipe caused by temperature and larger linear expansibility difference of the stainless steel pipe wall and the scale, the scale is easy to fall off, self cleaning of the pipe is achieved, and the scale removing problem of the condensation pipe is well solved; moreover, the pyramid lug bosses on the outer surface of the corrugated pipe increase the heat exchange area and puncture condensate membranes, so drops are easy to form and drop quickly along a wave crest, and the vapor-liquid conversion time is quickened. The pipe has light weight, high strength and quick heat transfer, and is superior to the prior structural copper pipe in economic benefit, service life and the like.

Description

technical field [0001] The invention relates to an air conditioner and a refrigerator, more specifically a high-efficiency non-scaling condensation pipe. Background technique [0002] At present, the condensers of air conditioners and refrigerators use copper tubes as condensing tubes for refrigeration. It uses equal-diameter smooth copper tubes for vapor-liquid heat exchange, and the hot gaseous refrigerant in the shell side is cooled by the cooling water in the copper tubes. into a liquid state, repeated cycle work, to achieve the cooling effect. [0003] The condenser pipe in this condenser absorbs heat with cooling water and performs heat exchange. When working, the temperature of the inner and outer walls of the tube is different. Because the cooling water in the equal-diameter light tube is in a laminar flow state when flowing, it is easy to scale; and the hot gaseous refrigerant will form a layer of liquid film when it meets the condenser tube. The outer surface of ...

AI Technical Summary

Problems solved by technology

But it has the same defects as the existing equal-diameter light copper tubes: first, it is easy to scale, and because of its small-diameter internal thread and thin and high teeth, it is more prone to scaling and difficult to remove, and the condensation effect is reduced after scaling ; Second, because of the small-diameter, thin and high-tooth internal thread, the wall thickness of the copper pipe is increased, which increases the production cost
