Description
Technical field
A kind of structure of idle call pipe fitting is the utility model is related to, specifically a kind of air-conditioning super-cooled pipe group assembly knot
Structure.
Background technology
Air-conditioning refrigeration system is mainly connected and composed by condenser, compressor, evaporator, supercooling tube group, and supercooling tube group is section
Original paper is flowed, its effect is to realize reducing pressure by regulating flow by restricting element to the refrigerant of high pressure-temperature, so as to obtain low-temp low-pressure
Refrigerant.The structure of existing idle call supercooling tube group assembly is more single, it is impossible to the self compensation of itself is carried out in throttling process
Regulation, so that the temperature for the refrigerant that supercooling tube group obtains and pressure have the problem of inconsistent, it is therefore necessary to conscientious to change
Enter.
Utility model content
The purpose of this utility model is to overcome the weak point of background technology, and it is total to provide a kind of air-conditioning super-cooled pipe group
Into structure.
To achieve these goals, the technical solution of the utility model is：Air-conditioning super-cooled pipe group assembly structure, including capillary
Pipe, filter and connecting tube, it is characterised in that：Also include return duct, the connecting tube includes main connecting tube and secondary connecting tube, institute
It is in integrally cylindrical barrel structure to state main connecting tube, and main connecting tube one end is connected with small flat pipe, and the other end is connected with big flat pipe,
The small flat pipe includes filter bores and the first return port, be connected between filter bores and the first return port it is small rise as high as the banks, big flat pipe bag
Secondary connecting hole and the second return port are included, is connected between secondary connecting hole and the second return port and rises as high as the banks greatly, the filter included
Chimney filter and transition conduit, the tapered tubular structure of transition conduit, and screen pipe and transition conduit are integral type structure, the screen pipe
Stainless steel filtering net is inside installed, described capillary one end is connected with transition conduit and screen pipe successively, and the other end is connected with filter bores,
Described return duct one end is connected with the first return port, and the other end is connected with the second return port, and described secondary connecting tube one end connects with secondary
Hole connection is connect, the other end is provided with locator protrusions.
In the above-mentioned technical solutions, the external diameter of the capillary and the external diameter of return duct are identical, the internal diameter of capillary and return
The internal diameter of flow tube is identical.
In the above-mentioned technical solutions, there are labeled slots in the main connecting tube.
Return duct in the utility model can help supercooling tube group to carry out the self compensation regulation of itself to a certain extent,
So that the temperature and pressure difference of the refrigerant obtained by the utility model are small.Simultaneously as filter is integral type knot
Structure, therefore filter of the present utility model is less likely to occur to leak, it is not necessary to welded again.
