Description
Technical field
The utility model relates to a kind of connecting tube, especially relate to a kind of for chiller plant can be around connecting tube.
Background technique
At present, existing chiller plant is split-type air conditioner for example, realize that by connecting tube both connect between its indoor units and the outdoor unit, the relative position of indoor units and outdoor unit does not have unified regulation, but changes according to the difference in the actual place of user.The connecting tube of prior art is unified caliber structure, bend or adopt multistage straight tube and bend pipe to be formed by fixedly connecting to body, such as Chinese patent notice of authorization number: CN 201187635Y, January 28 2009 notice of authorization day, a kind of composite connecting pipe is disclosed, by two-layer at least aluminum pipe combination, brazed tubes is also arranged on outer aluminum pipe again, the sectional shape of connecting tube is oval; The material of brazed tubes is the aluminum alloy of the 4 serial trades mark, and the sectional shape of connecting tube is non-circular, can increasing heat radiation area.Deficiency is, requirement because of as installed, need to carry out the one or many bending to body, inside an actor's rendering of an operatic tune of bending place body diminishes, so that reduce at the flow of bending place gas or liquid, and still having more than neededly at straight tube place flow, the normal circulation in connecting tube of gas or liquid is restricted.After bending, the phenomenon that stress is concentrated occurs in bending place easily, affects the installation strength of connecting tube.If the mode that adopts straight tube to combine with bend pipe, then the joint need to use welding to be fixed, cause managing interior gas or liquid leakage because of the solder joint failure welding easily in the actual mechanical process, there is serious potential safety hazard, and need straight tube is cut and bend pipe is selected before the welding, installation process comparatively bothers, and has greatly increased operator's workload, has reduced working efficiency.
The model utility content
The utility model is in order to overcome the deficiency that body internal rows cavity area dwindles after the bending of connecting tube in the prior art, provides a kind of body bent but the indeformable ripple of the inner an actor's rendering of an operatic tune of body can be around connecting tube.
To achieve these goals, the utility model is by the following technical solutions:
A kind of ripple of the present utility model can be around connecting tube, comprise integrated body, described body comprise at least one section bellows section and with the light pipe of bellows section adjacency, described bellows section comprises bellows and the corrugated connecting tube of alternative arrangement, and the caliber of described corrugated connecting tube and light pipe equates.Existing connecting tube is the structure that adopts unified caliber, and body inner an actor's rendering of an operatic tune in bending place is diminished.Therefore one end bellows section is set in the bending place, bellows section comprises bellows and corrugated connecting tube, when bending, mainly be that bellows deforms, and corrugated connecting tube deforms hardly, the caliber of corrugated connecting tube is identical with light pipe, and after the bending of bellows section, its inner an actor's rendering of an operatic tune remains unchanged like this, so that gas or liquid flow when flowing through connecting tube remains unchanged, the utilization ratio of connecting tube significantly improves.The light pipe of connecting tube and bellows section adopt integral forming process, need not to adopt welding manner to be connected and fixed, and improve the sealability of body, guarantee reliability and the working life of connecting tube.
As preferably, described bellows is the outer male structure of ring-type, rounding off between described bellows and the corrugated connecting tube.Bellows is done the circlewise structure of evagination, and its processing method is comparatively easy, and the caliber of bellows after the bending distortion, can not affect the size of inner an actor's rendering of an operatic tune greater than the caliber of corrugated connecting tube, guarantees that the flow of bellows section is identical with the light pipe part.The direct rounding off of bellows and corrugated connecting tube has improved the intensity of transition position, avoids occuring when bending the phenomenon that stress is concentrated.
As preferably, described light pipe one end and the first bellows section adjacency, the other end of described light pipe and the second bellows section adjacency.The two ends of light pipe are respectively in abutting connection with bellows section, so that the two ends of connecting tube all can bend, in order to satisfy different installation conditionss, improved the adaptability of connecting tube.
As preferably, described body two ends are respectively equipped with pipe end.Pipe end is set, and pipe end can change bore by moulding process such as scalable mouths makes it reach installation requirement, is convenient to the staff and installs.
As preferably, described body adopts wherein a kind of making of copper pipe, aluminum or aluminum alloy pipe, stainless steel or low-carbon (LC) welded pipe material.Because actual conditions are often comparatively complicated and changeable, can select the body of different materials for different environment and installation conditions, thereby improve its adaptability.
As preferably, the height of described bellows evagination is 1.0 ~ 5.0mm, and the pitch of waves between described two adjacent bellowss 1 is 2.0 ~ 16.0mm.Suitable bellows height and corrugated connecting tube width are set, are convenient to make production.
Therefore, the utlity model has following beneficial effect: the bellows section of (1) connecting tube is when bending, and its inner an actor's rendering of an operatic tune size does not change, and guarantees that gas or liquid are identical with flow in the light pipe in bellows section; (2) connecting tube is one-body molded, quality and the potential safety hazard of avoiding failure welding to cause.
