Abstract

The utility model relates to an air conditioner pipeline in an automobile air conditioning system, in particular to a combined high pressure and low pressure duplicate flow aluminum pipe. The utility model comprises an internal pipe and an external pipe. The internal pipe and the external pipe are bushed; a clearance between the internal pipe and the external pipe forms an external pipe cavity; a reinforcing bar is adopted to fix the internal pipe and the external pipe. The utility model has the advantages that: the utility model has a shapeable twisting property that is conducive for the installation of the pipeline and combines the inlet pipe and the outlet pipe in the traditional air conditioning pipeline, so as to reduce the cold loss in the system, enhance the cooling efficiency. Besides, in the transmission pipeline for the high pressure refrigeration medium and low pressure refrigeration medium of the traditional automobile air conditioning system, the utility model reduces the number of pipelines and realizes more compact installation.

Description

A kind of high-low pressure integrated type amphimorphic flow aluminium tube

Technical field

The utility model relates to a kind of air-conditioning duct of automotive air-conditioning system, more specifically, relates in particular to a kind of high-low pressure integrated type amphimorphic flow aluminium tube.

Background technique

In air-conditioning system, refrigerant transmits by pipeline, and according to refrigeration principle, refrigerant is exported from compressor high-voltage end by two pressure pipes, is refluxed by low voltage terminal.Therefore separate connection, the insulation respectively of these two pressure pipes cause pipeline numerous, increased the trouble of installing, especially obvious in the car body of pursuing large space, compact design especially.Pipeline increases the loss that also can cause along Cheng Lengliang simultaneously, has reduced the refrigeration of system.

Summary of the invention

The purpose of this utility model is in order to solve the deficiencies in the prior art, provide and have plastic bending properties, satisfy the position installation requirement of automobile refrigerating system pipeline, easy for installation, reduce the loss of refrigeration capacity of refrigeration system delivery line, improve a kind of high-low pressure integrated type amphimorphic flow aluminium tube of refrigerating efficiency.

The utility model is achieved through the following technical solutions:

The utility model is a kind of high-low pressure integrated type amphimorphic flow aluminium tube, pipe and outer tube in it includes, and interior pipe and outer tube sleeve installing are put and are left the gap and form the outer tube tube chamber, fix by stiffening rib between two pipes.

Pipe and outer tube are the aluminum pipe by the aluminium ingot extrusion modling in above-mentioned;

Pipe and outer tube are straight shape pipe in above-mentioned, have the performance made of brake forming.

This two density current pipes, profile is a kind of aluminum pipe of ring, be provided with some connection stiffening ribs in the pipe, connect stiffening rib by this and be connected with roundlet pipe in the pipe, form the combination body that big pipe box tubule has double properties of flow, the cooling medium of high pressure is carried at interior pipe, and the cooling medium of low pressure refluxes at outer tube, be connected with refrigeration system equipment by a double stream interface, the corresponding connection of high low pressure interface with this equipment forms an airtight loop.The position that pipeline is installed in air-conditioning system is owing to be full of twists and turns, and the connection stiffening rib in the pipe should reach the pipeline bending properties and require in intensity, bending properties design, be satisfied with the cooling medium consumption that low pressure refluxes simultaneously.

The beneficial effects of the utility model are: (1) has the installation that plastic sheathed is more convenient for pipeline; (2) with traditional air-conditioning into and out of two kinds of pipeline two-in-one, reduced the loss of system's cold, improved refrigeration; (3) in the high and low pressure refrigerant delivery line of automotive air-conditioning system, reduced the quantity of pipeline, install compact more.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As Fig. 1, shown in Figure 2, the utility model is a kind of high-low pressure integrated type amphimorphic flow aluminium tube, pipe 7 and outer tube 11 double pipes in it includes, body is by the aluminum pipe of aluminium ingot through extrusion modling, cross section structure is shown in the schematic representation among Fig. 2, be provided with some stiffening ribs 8 between interior pipe 7 and the outer tube 11, to guarantee managing the cooling medium of tube chamber 9 and outer tube tube chamber 10 in the two density current pipes by flow and compressive strength, according to designing requirement, the performance made with brake forming (curved part 6) is that body can be straight shape pipe and also can be crooked shape pipe by the two density current pipes of aluminum material after extrusion modling.Two density current pipes connect by double stream interface A1 and double stream interface B3 and refrigeration system equipment, on double stream interface, be provided with a high voltage interface end 4 and low-voltage interface end 5, the inlet and outlet connectors of high low pressure in their difference connecting systems, form circuitous closed cycle refrigeration system, reach the cooling medium course of conveying requirement of refrigeration system.

In sum, the utility model is a kind of air-conditioning duct that is applicable to the transmission of the high and low pressure cooling medium in the air-conditioning refrigeration system, particularly is applied to the air-conditioning duct of automotive air-conditioning system.Can substitute the double hose high low pressure delivery line of conventional refrigeration, have easy for installationly, satisfy the usage requirement of air-conditioning system, meet the environmental requirement of energy-saving material-saving.
