Abstract
Piping for an air conditioner heat exchanger is mainly composed of a U pipe (1), fins (2), a side board (3), a piping body (7) and a single connector (4), wherein the piping body (7) is located between the U pipe (1) of the heat exchanger and the single connector (4) and composed of a first end part (71), a second end part (73) and a middle part (72). The outer end of the first end part (71) is connected to the single connector (4), the second end part (73) entirely extends into the U pipe (1) and is attached to the inner wall of the U pipe, and the middle part (72) extends into the U pipe and welded with a horn port of the U pipe at a position of the outer end face of the middle part. Due to the fact that only one independent piping body is arranged between the U pipe of the heat exchanger and the single connector, in the heat exchanger with the piping, the piping body and the U pipe need to be welded only at the position of the horn port. Compared with two piping bodies in the prior art, the piping for the air conditioner heat exchanger is simple in structure, convenient to machine and lower in cost due to the fact that an unloading process and a welding process are eliminated, and large welding control space does not need to be left outside the horn port in advance.
Description
Technical field
The utility model relates to a kind of pipe arrangement of air-condition heat exchanger, belongs to the structure optimization field of air-condition heat exchanger.
Background technology
As shown in Figure 1, existing air-condition heat exchanger mainly is made up of U pipe 1, fin 2, side plate 3, pipe arrangement 26, pipe arrangement 1, single joint 4 etc.Wherein, pipe arrangement 26, pipe arrangement 1 are between the U of heat exchanger pipe 1 and single joint 4; Pipe arrangement 26 is made up of end 1, end 2 63, middle part 62, and end 1 is enclosed within on the pipe arrangement 1, and end 2 63 is all stretched in the U pipe 1 and the U inside pipe wall of fitting, and middle part 62 parts stretch into the U pipe; The other end of pipe arrangement 1 is connected on single joint 4.
In this air-condition heat exchanger, the inner diameter D 1 of U pipe 1 is identical with the external diameter of end 2 63; The outside diameter d 2 at middle part 62 is greater than D1; The format diameter of single joint 4 is identical with the outside diameter d 1 of end 1.
In this air-condition heat exchanger, pipe arrangement 26 and U pipe 1 need weld at horn mouth place 11, and pipe arrangement 26, pipe arrangement 1 need be in the end 12 weld, and so just need twice blanking operation and welding sequence.In addition, for making things convenient for welding operation, enough distance L must be left in 12 of horn mouth place 11 and ends.
The utility model content
The utility model is to optimize the structure of existing air-condition heat exchanger, make simple in structure, easy to process, cost is lower.
For this reason, the utility model provides a kind of pipe arrangement for air-condition heat exchanger, and between the U of heat exchanger pipe and single joint, it is characterized in that: this pipe arrangement is made up of end one, end two, middle part; The outer end of its medial end portions one is connected on above-mentioned single joint, and its medial end portions two all stretches in the above-mentioned U pipe and the U inside pipe wall of fitting, and wherein the middle part is stretched into the U pipe and welded with the horn mouth of its place, outer face and U pipe.
As the preferred a kind of pipe arrangement of the utility model, be further characterized in that: the inner diameter D 1 of above-mentioned U pipe and the external diameter of end two are 8.9mm; The outside diameter d 2 at above-mentioned middle part is 9.52mm; The outside diameter d 1 of the format diameter of above-mentioned single joint and end one is 6mm.
Owing between the U of heat exchanger pipe and the single joint an independently pipe arrangement is only arranged, therefore adopts the heat exchanger of this pipe arrangement only to need pipe arrangement and U pipe to carry out place welding at the horn mouth place.Existing relatively 2 pipe arrangements have not only omitted one blanking operation and welding sequence, also need not to reserve bigger welding and control the space outside horn mouth.Therefore, the air-conditioner heat exchanger structure of employing pipe arrangement is simple, easy to process, cost is lower.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of existing air-condition heat exchanger; For clarity sake, adopted broken section and the fracture technique of painting, and omitted the part parts;
Fig. 2 is the structural representation of the air-condition heat exchanger of employing the utility model pipe arrangement; For clarity sake, adopted broken section and the fracture technique of painting, and omitted the part parts.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, this air-condition heat exchanger mainly is made up of U pipe 1, fin 2, side plate 3, pipe arrangement 7, single joint 4 etc.Pipe arrangement 7 is made up of end 1, end 2 73, middle part 72 between the U of heat exchanger pipe 1 and single joint 4.Wherein, the outer end of end 1 is connected on single joint 4; End 2 73 is all stretched in the U pipe 1 and the U inside pipe wall of fitting; Middle part 72 is stretched into U pipe and is welded with the horn mouth of its place, outer face and U pipe.The inner diameter D 1 of U pipe 1 and the external diameter of end two are 8.9mm; The outside diameter d 2 at middle part 72 is 9.52mm; The format diameter of single joint 4 and the outside diameter d 1 of end 1 are 6mm.
In this air-condition heat exchanger, owing between the U of heat exchanger pipe 1 and the single joint 4 an independently pipe arrangement 7 is only arranged, therefore only need pipe arrangement 7 and U pipe 1 21 to carry out place welding at the horn mouth place.Existing relatively 2 pipe arrangements have not only omitted one blanking operation and welding sequence, also need not to consider to reserve bigger welding and control the space horn mouth 11 outside, and the air-conditioner heat exchanger structure of employing pipe arrangement is simple, easy to process, cost is lower.
More than be one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, on the basis of above-described embodiment, can do multiple variation, can realize the purpose of this utility model equally.But this variation obviously should be in the protection domain of claims of the present utility model.
