Abstract

The utility model discloses a kind of coaxial tubular construction used for automobile air conditioning, a kind of coaxial tubular construction used for automobile air conditioning, include outer tube including body described in body, the inner chamber of the outer tube is socketed with inner tube, and be fixedly connected between inner tube and outer tube by multiple support frames, on inner pipe, the outer rim of support frame is multiple fins that cooperation is shored with outer tube madial wall to spaced suit between support frame.The effect that the utility model passes through outer tube, support frame and inner tube, tubular body can be made to have a space, when the refrigerant system is operating, high temperature refrigerant is set to be flowed in the inner chamber of inner tube, low-temperature refrigerant flows in the space that outer tube is connected with inner tube, improves heat exchange efficiency, reduces the refrigerant temperature in high-voltage tube, the refrigerant temperature into throttle mechanism is reduced, the circulating rate of the different refrigerants of high/low temperature is accelerated.

Description

A kind of coaxial tubular construction used for automobile air conditioning

Technical field

The utility model is related to automobile air conditioning technology field, specially a kind of coaxial tubular construction used for automobile air conditioning.

Background technology

With the fast development of society, the economic level of people is also constantly being improved, and increasing family have purchased Automobile, the species of automobile is various, and price differs greatly, and people are general using having many uses too for automobile, it is well known that air conditioning for automobiles It is the equipment for completing regulation air in a car compartment environment as cost to use the power of engine, and automobile many times all stops It is placed on ground, so as to directly be influenceed by sunlight, frost and snow, wind and rain etc., causes vehicle body environmental change acutely, to make vapour Car air-conditioning is efficiently run in such environment, it is desirable to which its refrigerating capacity is especially big, thus considerably increases the work of engine Load, greatly improves the coefficients such as oil consumption, but existing refrigeration piping is all single layer structure, it is impossible to which refrigerant heat is handed over Change, so that refrigeration is reduced, therefore, a kind of it is proposed that coaxial tubular construction used for automobile air conditioning.

Utility model content

The purpose of this utility model is to provide a kind of coaxial tubular construction used for automobile air conditioning possess exchange refrigerant heat Advantage, solve existing refrigeration piping all be single layer structure, it is impossible to refrigerant heat is swapped, so as to reduce system The problem of cold effect.

To achieve the above object, the utility model provides following technical scheme：A kind of coaxial tubular construction used for automobile air conditioning, Include outer tube including body described in body, the inner chamber of outer tube is spaced a distance provided with inner tube and with outer tube madial wall, and inner tube It is fixedly connected between outer tube by multiple support frames, spaced between support frame to be set with inner pipe, the outer rim of support frame For multiple fins that cooperation is shored with outer tube madial wall.

The beneficial effects of the utility model are as follows：Body of the present utility model is made up of outer tube and inner tube, outer tube and inner tube Between supported by support frame interval, tubular body can be made to have a space, when the refrigerant system is operating, high temperature refrigerant is existed Flowed in the inner chamber of inner tube, low-temperature refrigerant flows in the space that outer tube is connected with inner tube, improves heat exchange efficiency, reduce Refrigerant temperature in high-voltage tube.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model support frame structure schematic diagram.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.

As Figure 1-Figure 2, the utility model includes body 1, and body 1 includes outer tube 11, and the inner chamber of outer tube 11 is set There is inner tube 13 and be spaced a distance with outer tube madial wall, and company is fixed by multiple support frames 12 between inner tube 13 and outer tube 11 Connect, on inner pipe, the outer rim of support frame shores the convex of cooperation to spaced suit to be multiple with outer tube madial wall between support frame Rib 14.Inner tube 13 and outer tube 11 are aluminum pipe, and the thickness of inner tube 13 and outer tube 11 is two millimeters.

In use, because body 1 is made up of outer tube 11 and inner tube 13, can make have a space inside body 1, when refrigeration system During system work, high temperature refrigerant is set to be flowed in the inner chamber of inner tube 13, the sky that low-temperature refrigerant is connected in outer tube 11 with inner tube 13 Flowed in gap, improve heat exchange efficiency, reduce the refrigerant temperature in high-voltage tube, make the refrigerant temperature into throttle mechanism Reduction.In summary：The coaxial tubular construction used for automobile air conditioning, by outer tube 11, support frame 12 and inner tube 13 and in support The inner surface of frame 12 has opened up hollow hole to be set with inner pipe, and it is all single layer structure, nothing to solve existing refrigeration piping Method is swapped to refrigerant heat, so that the problem of reducing refrigeration.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
