Abstract
The invention discloses a heat exchanging air-conditioning pipeline for a vehicle. The heat exchanging air-conditioning pipeline for the vehicle comprises an outer pipe and an inner pipe. A part of the inner pipe is arranged inside the outer pipe. The two ends of the outer pipe serve as the end connected with an inlet of an evaporator and the end connected with a condenser respectively. The two ends of the inner pipe serve as the end connected with an outlet of the evaporator and the end connected with a compressor respectively. The inner wall of the outer pipe is provided with protruding ribs. Due to heat exchanging between high-pressure liquid inside the outer pipe and low-pressure liquid inside the inner pipe, the temperature of gas entering the compressor is increased, and meanwhile the temperature of liquid before entering an expansion valve is further lowered. Due to the protruding ribs on the inner wall of the outer pipe, the heat exchanging effect is improved, the structural stability is enhanced, the refrigerating capacity of an air-conditioning system is improved, the energy efficiency ratio of an air conditioner is increased, and the oil consumption of the vehicle can be lowered.
Description
Technical field
The present invention relates to automobile air conditioning technology field, especially relate to a kind of automobile heat-exchanging air conditioner pipeline.
Background technology
Along with the development of automobile industry, quality for automobile various aspects is pursued higher, wherein, existing pipelines of automobile air conditioner high-low pressure pipeline adopts two pipelines separately, these two line arrangement are in enging cabin, low pressure line low temperature can absorb heat loss energy, and pressure duct cannot dispel the heat and can reduce air-conditioning system refrigeration performance.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide a kind of automobile heat-exchanging air conditioner pipeline, to reach the object improving air-conditioning system refrigeration performance.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of automobile heat-exchanging air conditioner pipeline, comprise outer tube and interior pipe, described inner pipe portion is arranged in outer tube, the two ends of described outer tube are respectively and connect evaporator end and be connected condenser end, the two ends of described interior pipe are respectively and connect evaporator outlet end and be connected compressor end, and described outer tube wall is provided with raised ribs.
Further, described outer tube medium flows to and flows to contrary with interior pipe medium.
Described inner and outer tubes are aluminum pipe.
Raised ribs on described outer tube wall is along outer axial tube to setting.
Raised ribs on described outer tube wall contacts with outer wall of inner tube.
The present invention compared with prior art, have the following advantages: by the heat exchange between the low-pressure gas in the highly pressurised liquid in outer tube and interior pipe, improve the gas temperature entering compressor, reduce the fluid temperature before entering expansion valve further simultaneously, improve heat transfer effect by the raised ribs on outer tube wall and increase structural stability, improve the refrigerating capacity of air-conditioning system and the Energy Efficiency Ratio of air-conditioning, the oil consumption of automobile can be reduced.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is air-conditioning duct structural representation of the present invention.
Fig. 2 is along A-A sectional view in Fig. 1.
In figure: 1. outer tube, 101. connection evaporator ends, 102. connect condenser end, 2. interior pipe, 201. and connect evaporator outlet ends, 202. connection compressor ends.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, this automobile heat-exchanging air conditioner pipeline, comprise outer tube 1 and interior pipe 2, interior pipe 2 part is arranged in outer tube 1, the two ends of outer tube are respectively and connect evaporator end 101 and be connected condenser end 102, the two ends of interior pipe are respectively and connect evaporator outlet end 201 and be connected compressor end 202, and outer tube wall is provided with raised ribs.
Interior pipe 2 and outer tube 1 are aluminum pipe, and outer tube is high-voltage tube, and outer tube two ends are connected with evaporator, condenser respectively, pass through high temperature high pressure liquid in outer tube; Interior pipe is low-voltage tube, and interior pipe two ends are connected with evaporator outlet, compressor respectively, pass through low temperature low pressure gas in interior pipe.
Outer tube medium flows to and flows to contrary with interior pipe medium; Further, the interior pipe part be located in outer tube is positioned at the center of outer tube, and interior pipe 2 is provided with helicla flute 203, and helicla flute is squeezed out by common aluminum pipe outer wall, and spiral fluted pitch is the arc spiral groove of 30mm.
Raised ribs on outer tube wall is along outer axial tube to setting, and raised ribs is seven of being distributed on outer tube inner periphery, and the raised ribs on outer tube wall contacts with outer wall of inner tube.Improve heat transfer effect by the raised ribs on outer tube wall, by the raised ribs cutting ferrule on outer tube wall on inner pipe, Stability Analysis of Structures is reliable.
Interior pipe out partly seals from outer tube, by the heat exchange between outer tube mesohigh liquid and interior pipe mesolow gas, improves the gas temperature entering compressor, reduces the fluid temperature before entering expansion valve further simultaneously.
The flow of refrigerant in interior pipe can be controlled by helicla flute, and the contact area with medium can be increased, propose high-octane exchange.
Utilize this air-conditioning duct, average raising cooling system amount about 5%, improves the Energy Efficiency Ratio COP about 16% of air-conditioning; Under different operating mode, heat-exchanging air conditioner pipeline has cooling system amount and COP and improves in various degree, and improve obviously in air-conditioning bad working environments (idling outer circulation), refrigerating capacity and COP improve 14.7% and 20.0% respectively; Set up heat-exchanging air conditioner pipeline and obviously accelerate real vehicle rate of temperature fall, after about 15min, leaving air temp decreases than original system, after real vehicle runs about 45min, on average reduces about 1.5 DEG C than general refrigerating cycle system leaving air temp; Set up heat-exchanging air conditioner pipeline fuel consumption per hundred kilometers and reduce about 0.1L-0.3L.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
