Abstract
The utility model relates to a heat exchanger, more specifically, a heat transfer copper pipe applied to a central air-conditioner. According to the technical project provided by the utility model, internal teeth are designed in the internal wall of the copper pipe body and the internal teeth are characterized in that the internal teeth are thread, wherein, the tooth height of one thread is h1 and the tooth height of another thread is h2. The difference between the tooth height h2 and h1 is delta. The top tooth face of the thread is situated in the same cylindrical surface. Because of the different thread tooth height in the inner wall of the metal pipe, the heat dissipation area and heat dissipation effect of the metal pipe can be increased and improved.
Description
Technical field
The utility model relates to heat exchanger, specifically a kind of heat transmitter copper pipe that is applicable to central air-conditioning.
Background technology
In the prior art, the radiator copper pipe that uses in the air-conditioner normally outer wall has the form of screw thread, inner wall smooth.During work, medium flows in pipe, realizes heat exchange by copper pipe tube wall and environment, and wherein, the screw thread of copper pipe outer wall is used to increase area of dissipation, improves radiating effect.But present this screw thread tooth depth all is the same, and does not have screw thread at the inwall of copper pipe, thereby medium when mobile, is in laminar condition substantially in pipe, has influence on the radiating effect of copper pipe.
The utility model content
The purpose of this utility model is to design a kind of special-shaped internal thread radiator metal tube, because the screw thread tooth depth of this inner wall of metal tube is different, has increased the area of dissipation of metal tube, has improved the radiating effect of metal tube.
According to design provided by the utility model, at the inwall of copper pipe body internal tooth is arranged, it is characterized in that: internal tooth is a thread, and the tooth depth of one of them thread is h1, and the tooth depth of another thread is h2, and poor δ is arranged between tooth depth h2 and h1.
The crest top land of thread is positioned at the same face of cylinder.Two threads are adjacent tooth.The outer wall of body has external tooth, and external tooth is similarly thread, and the tooth depth of one of them thread is h1, and the tooth depth of another thread is h2, and poor δ is arranged between tooth depth h2 and h1.
The utility model has the advantages that: owing on the copper pipe tube body wall of thin-walled, be provided with the abnormal screw thread tooth that tooth depth does not wait, make the utility model when the characteristic that keeps original standard thread tooth to be had, further increased the area of dissipation of copper pipe, thereby, improve heat exchange coefficient, improved heat exchange property.Secondly, after the inwall of body was provided with screw thread, when medium flowed in pipe, the meeting turbulization made medium be in turbulent condition, thereby further improves heat exchanger effectiveness.In addition, after being provided with this abnormal screw thread tooth on the tube body wall, the intensity after being convenient to the copper pipe bending and increasing bending.
Description of drawings
Fig. 1 is the copper pipe axial section.Fig. 2 is the cross-sectional view of common copper pipe.
Fig. 3 is standard thread profile of tooth figure.Fig. 4 is the thread tooth figure of abnormity.
The specific embodiment
As shown in the figure: the inwall at copper pipe body 1 has internal tooth 3.Internal tooth 3 is an abnormal screw thread tooth 4,5, and wherein, the tooth depth of a thread 5 is h1, and the tooth depth of another adjacent thread 4 is h2, and poor δ is arranged between tooth depth h2 and h1.After copper pipe surface is provided with the abnormal screw thread tooth that this tooth depth do not wait, at the area of dissipation that further increases body, improve radiating efficiency in, the intensity after also being convenient to the copper pipe bending and increasing bending.
The crest top land of the thread 4,5 of internal tooth 3 is positioned at the same face of cylinder.Make whole copper pipe when increasing area of dissipation, keep profile to original similar.For ease of using and installing, the end of copper pipe body is the inclined-plane of 30 degree.
Claims (5)
