Abstract
The utility model discloses a composite pipe structure for an air-conditioner pipeline, which is characterized in that a composite pipe is formed by a composite inner pipe nested with a composite outer pipe; the composite inner pipe is arranged in the inner chamber of the composite outer pipe; the inner wall of the inner chamber of the composite outer pipe is provided with a projection; the projection is integrated with the inner wall of the inner chamber of the composite outer pipe; the end of the projection is contacted with the outer wall of the composite inner pipe and is fixed with each other. The composite pipe structure can composite the high-pressure pipe and the low-pressure pipe in a certain sectional pipeline for heat exchange, thus improving the air-conditioning system efficiency, saving the energy and protecting the environment. Compared with prior art, the utility model has obvious substantive features and makes remarkable progress.
Description
Technical field:
The utility model relates to the technical field of air-conditioning system heat-exchange device, a kind of specifically composite pipe structure that is used for air-conditioning duct, particularly its mechanical connecting structure.
Background technology:
The air conditioning for automobiles industry is being faced with new technological innovation now.For the consideration of energy savings and protection environment, the air conditioning for automobiles industry is just preparing to use new cold-producing medium (HFO1234yf) to replace existing cold-producing medium.New cold-producing medium is owing to the restriction of performance, its refrigeration not ideal enough under original air-conditioning system (be mainly reflected in refrigeration and can not reach requirement).This just needs to improve air-conditioning system efficient, this shows that the improvement of air-conditioning system is imperative.
So still need existing air conditioning for automobiles heat-exchange tube line structure is further improved.
The utility model content:
The purpose of this utility model is to provide a kind of composite pipe structure that is used for air-conditioning duct, it adopts the inner and outer pipes composite construction, interior pipe and outer tube carry out heat exchange by heat-conducting piece, thereby effectively improve air-conditioning system efficient, energy savings, and it has overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of composite pipe structure that is used for air-conditioning duct, it mainly comprises compound body, it is characterized in that: described compound body is socketed to form by multiple tube inner tube and multiple tube outer tube, multiple tube inner tube is positioned at the multiple tube outer tube bore, and the inwall punishment of multiple tube outer tube bore is furnished with lug boss, and the inwall of lug boss and multiple tube outer tube bore is integrative-structure, the end of lug boss is touched mutually with the multiple tube inner tube outer wall, and interfixes.
The utility model discloses a kind of composite pipe structure that is used for air-conditioning duct; can be implemented in a certain section pipeline carries out high-voltage tube and low-voltage tube compound; allow them carry out heat exchange each other; thereby reach the effect that improves air-conditioning system efficient, energy savings, protection environment;, product has outstanding substantive distinguishing features and marked improvement compared to existing technologies.

The specific embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of composite pipe structure that is used for air-conditioning duct, it mainly comprises compound body 1, it is different from prior art and is: described compound body 1 is socketed to form by multiple tube inner tube 2 and multiple tube outer tube 3, multiple tube inner tube 2 is positioned at multiple tube outer tube 3 inner chambers, the inwall punishment of multiple tube outer tube 3 inner chambers is furnished with lug boss, the inwall of lug boss and multiple tube outer tube 3 inner chambers is integrative-structure, and the end of lug boss is touched mutually with multiple tube inner tube 2 outer walls, and interfixes.
In the specific implementation, described lug boss is a heat conduction bar 4, and heat conduction bar 4 evenly distributes at the inwall of multiple tube outer tube 3 inner chambers, and heat conduction bar 4 parallels with multiple tube outer tube 3 trends, and the end of heat conduction bar 4 is touched mutually with multiple tube inner tube 2 outer walls, and interfixes.The cross section of described multiple tube outer tube 3 is the circular ring body of straight-tooth 5 in the band.
Described multiple tube outer tube 3 outer cover are connected to adapter 6, and adapter 6 places offer connecting hole 7, and connecting hole 7 is fixedlyed connected with the heading 9 of high-voltage tube 8 ends, and described multiple tube inner tube 2 is connected with low-voltage tube 10 ends.
In the specific implementation, described multiple tube inner tube 2 and multiple tube outer tube 3 are the metallic aluminium material, and heat conduction bar 4 also is the metallic aluminium material, and aluminum pipe helps the effect of heat exchange.
As shown in Figure 5, the title of each symbol: P is that pressure, bar are the unit of pressure, 1bar=100000Pa, HP are that high pressure, LP are that low pressure, h are specific heat, Kal/Kg is a specific heat capacity, be the heat that every kilogram of cold-producing medium changes once required release or absorption, 1Kal=12353J, Q are heat, 1,2,3,4,5,6 corresponding with figure below, and 3,4,5 is high-voltage tube, 1,2,6 is low-voltage tube, and 1,2,4,5 is the multiple tube part.
