Description
Technical field
The utility model relates to air conditioner industry technical field, particularly a kind of pipe arrangement for air-condition heat exchanger.
Background technology
Existing air-condition heat exchanger, mainly by one-tenth such as U pipe, fin, side plate, pipe arrangement two, pipe arrangement one, single joints.Wherein, pipe arrangement two, pipe arrangement one are between the U of heat exchanger pipe and single joint; Pipe arrangement two is made up of end one, end two, middle part, and one end of pipe arrangement one is closely nested in end one, and end two is all stretched in U pipe and the U inside pipe wall of fitting, and middle part part stretches in U pipe; The other end of pipe arrangement one and single joint are fixedly connected.In this air-condition heat exchanger, pipe arrangement two and U pipe need to weld at horn mouth place, pipe arrangement two, pipe arrangement one need to weld in end, although adopt welding firmly, but also there is the problem that affects welding quality because of rosin joint, change pipe arrangement needs special soldering appliance simultaneously, brings difficulty to follow-up maintenance.Therefore, how to optimize the syndeton of pipe arrangement, further improve product assembly quality, provide the problems such as manageable product to become the focus of studying in industry for client.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of pipe arrangement for air-condition heat exchanger simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of pipe arrangement for air-condition heat exchanger described in the utility model, comprise U pipe, fin, side plate, pipe arrangement and single joint, the two ends of described pipe arrangement are provided with external thread section, one end interference of described U pipe is nested with joint sleeve, the external thread section of pipe arrangement one end is threaded mutually with the internal thread of joint sleeve, and the external thread section of the pipe arrangement other end is threaded mutually with the internal thread of single joint one end.
Further, described joint sleeve is by little straight length, inclination pipeline section and large straight length, is closely nested with the conical seal ring matching with the pipeline section that tilts in female connector pipe.
Further, between the described pipe arrangement other end and single joint one end, be provided with sealing ring two.
Further, described pipe arrangement inner surface is provided with internal thread, is evenly provided with several double wedges on internal thread.
Adopt after said structure, the utility model beneficial effect is: a kind of pipe arrangement for air-condition heat exchanger described in the utility model, comprise U pipe, fin, side plate, pipe arrangement and single joint, the two ends of described pipe arrangement are provided with external thread section, one end interference of described U pipe is nested with joint sleeve, the external thread section of pipe arrangement one end is threaded mutually with the internal thread of joint sleeve, and the external thread section of the pipe arrangement other end is threaded mutually with the internal thread of single joint one end.In the time using the utility model, employing is threaded, and avoids welding sequence in the past, has not only improved production efficiency, has guaranteed the quality of connection of pipe fitting, and can facilitate for the work of follow-up maintenance.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of pipe arrangement for air-condition heat exchanger described in the utility model, comprise U pipe 1, fin 2, side plate 3, pipe arrangement 5 and single joint 6, the two ends of described pipe arrangement 5 are provided with external thread section, one end interference of described U pipe 1 is nested with joint sleeve 4, the external thread section of pipe arrangement 5 one end is threaded mutually with the internal thread of joint sleeve 4, and the external thread section of pipe arrangement 5 other ends is threaded mutually with the internal thread of single joint 6 one end.
As a kind of optimal way of the present utility model, as shown in Figure 1-2, described joint sleeve 4 is by little straight length 4-1, inclination pipeline section 4-2 and large straight length 4-3, the interior conical seal ring 7 matching mutually with the pipeline section 4-2 that tilts that is closely nested with of female connector pipe 4.Can improve like this pipe arrangement 5 and joint sleeve 4 connection sealing energy.
As a kind of optimal way of the present utility model, between described pipe arrangement 5 other ends and single joint 6 one end, be provided with sealing ring two; Can improve like this pipe arrangement 5 and single joint 6 connection sealing energy.
As a kind of optimal way of the present utility model, described pipe arrangement 5 inner surfaces are provided with internal thread 8, are evenly provided with several double wedges 8-1 on internal thread 8, can improve like this efficiency of pipe arrangement 5 hot and cold exchanges.
In the time using the utility model, employing is threaded, and avoids welding sequence in the past, has not only improved production efficiency, has guaranteed the quality of connection of pipe fitting, and can facilitate for the work of follow-up maintenance.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
