Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning heat exchange, in particular to an end connection structure of a condensing pipe for an air-conditioning. Background Art

[0002] The thermal resistance of high-efficiency heat exchange tubes is mainly distributed outside the tubes. Therefore, improving the heat exchange performance outside the tubes is crucial to improving their heat transfer performance. Discharging the liquid refrigerant condensed on the surface of the condenser tubes in time can effectively improve the heat exchange performance outside the tubes.

[0003] At present, condensers are made of metal pipes such as copper pipes, aluminum pipes, and plastic pipes. When installing and using them, it is necessary to cut condensers of different lengths according to the site conditions, and make pipe joints on site for connection, which is labor-intensive and time-consuming and not conducive to installation. For this reason, the present application discloses a condenser end connection structure for air conditioners. Utility Model Content

[0004] The utility model aims to solve the existing problems and provides a condenser pipe end connection structure for air conditioners.

[0005] The utility model is realized by the following technical scheme: a condenser pipe end connection structure for air conditioner, comprising a condenser pipe body, the condenser pipe body is covered with a cotton pipe layer, the end of the condenser pipe body is integrally connected to an external threaded end pipe, and the external threaded end pipe is threadedly connected to a screw seat;

[0006] The screw seat comprises a pipe sleeve, and the two ends of the pipe sleeve are symmetrical and rotatably connected to the screw sleeve.

[0007] As a further improvement of the above scheme, inner groove rings are provided at both ends of the pipe sleeve, a hook ring is provided at the outer end of the inner groove ring, the hook ring is clamped on the outside of the outer groove ring, the outer groove ring is connected to one end of the screw sleeve, an outer convex ring is provided at the end of the outer groove ring away from the screw sleeve, the outer convex ring is clamped in the inner groove ring, and is used to connect the end pipes of the two condenser tubes.

[0008] As a further improvement to the above scheme, the inner diameter of the tube sleeve is smaller than the inner diameter of the screw sleeve, and is used to connect the end tubes of the two condenser tubes so that the end tubes of the two condenser tubes are at the ends of the tube sleeve, thereby preventing the end tubes of the two condenser tubes from being squeezed and deformed.

[0009] As a further improvement to the above solution, a sealing ring is provided on the end surface where the hook mouth ring and the outer convex ring are clamped, so as to seal the rotating connection end surface between the pipe sleeve and the screw sleeve to avoid leakage of the connection end surface.

[0010] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, by covering the condenser with a cotton tube layer to absorb the water droplets condensed on the outer wall of the condenser, and to absorb the dripping of small water balls condensed due to temperature difference; in addition, when the condenser is installed and used, the condenser is connected by a screw sleeve to increase the usable length of the condenser.

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 3 As shown in the figure, a condenser end connection structure for air conditioners comprises a condenser main body 1, the condenser main body 1 is covered with a cotton tube layer 2, the end of the condenser main body 1 is integrally connected to an externally threaded end tube 3, and the externally threaded end tube 3 is threadedly connected to a screw seat 4;

[0016] The screw seat 4 includes a pipe sleeve 5 , and the two ends of the pipe sleeve 5 are symmetrical and rotatably connected to the screw sleeve 6 .

[0017] As a further improvement to the above scheme, inner groove rings 9 are provided at both ends of the pipe sleeve 55, and a hook ring 10 is provided at the outer end of the inner groove ring 9. The hook ring 10 is clamped on the outside of the outer groove ring 7. The outer groove ring 7 is connected to one end of the screw sleeve 6. An outer convex ring 8 is provided at the end of the outer groove ring 7 away from the screw sleeve 6. The outer convex ring 8 is clamped in the inner groove ring 9 and is used to connect the joints of the two condenser pipes.

[0018] As a further improvement to the above scheme, the inner diameter of the pipe sleeve 5 is smaller than the inner diameter of the screw sleeve 6, and is used to connect the end tubes 3 of the two condenser tubes so that the end tubes 3 of the two condenser tubes are at the ends of the pipe sleeve 5, thereby preventing the end tubes 3 of the two condenser tubes from being squeezed and deformed.

[0019] As a further improvement to the above solution, a sealing ring 11 is provided on the end surface where the hook ring 10 and the outer convex ring 8 are clamped, so as to seal the rotating connection end surface between the pipe sleeve 5 and the screw sleeve 6 to avoid leakage of the connection end surface.

[0020] The working principle of a condenser end connection structure for air conditioners is as follows: the two end tubes 3 of the condenser to be connected are respectively threadedly connected to the two screw sleeves 6 of the screw seat 4, and the screw sleeve 6 is rotated so that the screw sleeve 6 stud is sleeved on the end tube 3 of the condenser, so that the two sections of the condenser are connected into a whole.
