Abstract
The invention relates to the technical field of vehicle air conditioning, in particular to a super-cooling pipeline. The super-cooling pipeline consists of an inlet pipe holder, an external pipe, an internal pipe, a heat sink strip and an outlet pipe holder and is characterized in: the external pipe, 3 to 8 heat sink strips and the internal pipe are formed by the one-time extrusion of aluminum products, and 3 to 8 heat sink strips in the internal cavity of the external pipe are arranged equidistantly for supporting the internal pipe; and both ends of the external pipe and the internal pipe are respectively welded together with the inlet pipe holder and the outlet pipe holder. The invention is simple in structure and convenient in installation, can be super-cool as well as substitute parts of original pipeline and has good refrigeration effect, thus being suitable for the use of automobile air conditioning systems.
Description
Technical field
The present invention relates to the automobile air conditioning technology field, especially relate to a kind of supercooling tube road.
Background technology
Automotive air-conditioning system mainly is made up of compressor, condenser, drier receiver, expansion valve and evaporator part, adopt rubber hose or metal tubes that the critical piece of air-conditioning system is connected into the refrigerating circulation of a sealing, just storage or circulate in the refrigerating circulation of this sealing of cold-producing medium.When air-conditioning system turns round, high temperature, high-pressure refrigerant vapor from the compressor discharge, enter condenser by high-pressure hose and can be condensed into higher temperatures and highly pressurised liquid, this higher temperatures and highly pressurised liquid enter drier receiver by high-pressure hose again, after drying and the filtration, enter evaporimeter by expansion valve again, the refrigeration steam that under level pressure, is vaporized into, compressed by the compression presses suction by low-voltage tube, circulation is gone down again and again like this.In circulating, during cold-producing medium process expansion valve,, produce and dodge the gas phenomenon because throttling action can make cold-producing medium evaporate on a small quantity, influenced flowing of cold-producing medium, cause the decline of air-conditioning system refrigerating efficiency.Automotive air-conditioning system under normal conditions, cold 1 ℃ of every mistake just improves coefficient of refrigerating performance about 0.85%.For making refrigerant temperature be lower than pairing saturation temperature under the condensing pressure, adopt some technical measures to cross cold cold-producing medium: (1) is cold excessively in condenser, when the condenser area is big, refrigerant liquid can be cold, because condenser self temperature height, and it is fast again to dispel the heat, and can not cross cold cold-producing medium effectively; (2) increase subcooler, cross cold cold-producing medium of discharging from condenser, though this subcooler cold excessively cold-producing medium, improved the air-conditioning system refrigerating efficiency, increased the little leakage of air-conditioning system parts, connecting tube, production cost and cold-producing medium, and difficulty relatively be installed.
Summary of the invention
Purpose of the present invention provides a kind of supercooling tube road at the technical problem of above-mentioned existence, and is simple in structure, crosses cold effectively, substitutes the original pipeline of part, easy for installation, is fit to automotive air-conditioning system and uses.
In order to achieve the above object, technical scheme of the present invention is: a kind of supercooling tube road, form by import base, outer tube, interior pipe, heat sink strip and outlet base, it is characterized in that: described outer tube and 3～8 heat sink strips and interior pipe are by the disposable extrusion modling of aluminium, and pipe in the equidistant support of 3～8 heat sink strips of outer tube bore; Described outer tube and interior pipe two ends are integrally welded with import base and outlet base respectively.
It is that the outlet by the outlet base flows into the expansion valve import again, is vaporized into gaseous state from expansion valve outlet inflow evaporator from the interior pipe of import inflow of liquid refrigerant by the import base of drier receiver outlet that the present invention crosses cold principle.The evaporimeter gaseous refrigerant flows into outer tube from the import of outlet base, and the outlet inflow compressor inlet from the import base is compressed into the HTHP gaseous state again.Because the gas-liquid on supercooling tube road circulation, then the higher temperatures liquid refrigerant is passed through interior pipe and heat sink strip, carry out heat exchange with the cryogenic gaseous cold-producing medium that flows into outer tube from evaporimeter, reduce expansion valve import liquid refrigerant temperature, reach, the gaseous coolant generating capacity of evaporator inlet is reduced the cold excessively effect of cold-producing medium, improved refrigerating efficiency, and substitute original part pipeline again, and saved production cost, easy for installation.

Fig. 1 is a cutaway view of the present invention;
Fig. 2 is a sectional view of the present invention;
Fig. 3 is a fundamental diagram of the present invention.
Among the figure, 1. import, 2. outlet, 3. import base, 4. outer tube, 5. in pipe, 6. outlet, 7. import, 8. outlet base, 9. heat sink strip.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention is by import base (3), outer tube (4), interior pipe (5), heat sink strip (9) and outlet base (8) are formed, described outer tube (4) and 3 heat sink strips (9) and interior pipe (5) are by the disposable extrusion modling of aluminium, and manage (5) in the equidistant support of outer tube (4) 3 heat sink strips of inner chamber (9); Described outer tube (4) and interior pipe (5) two ends are integrally welded with import base (3) and outlet base (8) respectively.
As shown in Figure 3, it is to manage (5) in import (1) inflow of liquid refrigerant by import base (3) of drier receiver outlet that the present invention crosses cold principle, outlet (6) from outlet base (8) enters the expansion valve import again, enters evaporimeter from the expansion valve outlet and is vaporized into gaseous state.The evaporimeter gaseous refrigerant flows into outer tube (4) from the import (7) of outlet base (8), and outlet (2) the inflow compressor inlet from import base (3) is compressed into the HTHP gaseous state again.The higher temperatures liquid refrigerant by interior pipe (5) and heat sink strip (9), and is carried out heat exchange from evaporimeter inflow outer tube (4) cryogenic gaseous cold-producing medium, reached the effect of cold cold-producing medium.
