[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.
[0024] As a first aspect of the present invention, a pipeline installation bracket is provided. like Figure 1 to Figure 6 As shown, the pipeline installation bracket includes a main body 10, and the main body 10 has a clip portion 11 for connecting pipelines. Since the pipeline installation bracket is connected with the pipeline by means of snap connection, the pipeline installation bracket will not damage the base material of the pipeline, thereby avoiding the pipeline damage in the subsequent use process, eliminating potential safety hazards, and ensuring the pipeline reliability of use. Meanwhile, the pipeline installation bracket of the present invention has the characteristics of simple structure and low manufacturing cost.
[0025] The clamping portion 11 in the present invention is a clamping concave portion, and the clamping concave portion is adapted to the circumferential side wall of the pipeline. like Figure 1 to Figure 6 In the illustrated embodiment, the clipping recess is a U-shaped groove, and the shape of the clipping recess is adapted to the circumferential side wall of the pipeline, so that the pipeline installation bracket has the characteristics of convenient installation. Since the snap-connecting concave portion is adapted to the circumferential side wall of the pipeline, it is possible to ensure that the two have sufficient contact area and the connection strength of the two is ensured.
[0026] like Figure 1 to Figure 6 In the embodiment shown, the body 10 is U-shaped. The U-shaped body 10 can not only ensure stable connection with the pipeline, but also has the characteristics of small size, light weight and material saving. Of course, the body 10 can also be configured as a hollow cylindrical body, or a hollow cylindrical body 10 with lateral openings. When installing the pipeline mounting bracket, it is necessary to separate the hollow cylindrical body 10 and the lateral openings. The hollow cylindrical body 10 is sleeved on the pipeline from one end of the pipeline. Since the contact area between the hollow cylindrical body 10 and the hollow cylindrical body 10 with side openings and the pipeline is large, the stress concentration is reduced, the pipeline installation bracket is prevented from damaging the pipeline during use, and the pipeline is guaranteed. The reliability of the mounting bracket.
[0027] Preferably, the size of the notch of the clamping portion 11 of the main body 10 is smaller than the outer diameter of the pipe body of the pipeline, and the arc segment of the inner wall of the clamping recess exceeds 180 degrees, so as to ensure that the pipeline installation bracket can be firmly clamped on the pipeline. When assembling, a special clamp can be used to fix the pipe mounting bracket to the pipe.
[0028] The pipeline installation bracket in the present invention further includes a fixed installation plate 20 , and one end of the fixed installation plate 20 is connected to the body 10 . Since the fixed installation plate 20 is provided, the main body 10 can be fixed at the position to be installed by the fixed installation plate 20, which increases the connection area and the stress area of the main body 10 in a disguised form, thereby ensuring that the pipeline installation bracket can be stably installed in the to-be-installed position location.
[0029] like Figure 1 to Figure 3 In a preferred embodiment shown, two pipeline mounting brackets with different structures are shown, and the difference between the two is that the connection angle between the fixed mounting plate 20 and the main body 10 is different. Among them, the fixed installation plate 20 in one pipeline installation bracket is L-shaped, and the fixed installation plate 20 is vertically arranged with the main body 10; extend. It should be noted that the connection angle between the fixed installation plate 20 and the main body 10 can be adaptively set according to actual installation requirements, so that the pipeline installation bracket can meet different installation requirements.
[0030] like Figure 1 to Figure 6 In the illustrated embodiment, the fixed mounting plate 20 has mounting holes 21 . Since the installation holes 21 are provided, it is convenient for the fastener to fix the pipeline installation bracket at the position to be installed. Preferably, the fasteners are screws.
[0031] In a not-shown embodiment, the pipeline installation bracket is only provided with the main body 10, the clamping part 11 of the main body 10 is fastened with the circumferential side wall of the pipeline, and the fasteners install the main body 10 at the position to be installed , or the body 10 is fixed at the to-be-installed position by welding, riveting, gluing, or the like.
[0032] The pipeline installation bracket in the present invention further includes a damping member, and the damping member is arranged on the clamping portion 11 . Since the damping member is provided, the friction coefficient between the pipeline installation bracket and the pipeline bracket is increased, and the two are prevented from being displaced from each other, so that the pipeline installation bracket has the characteristics of stable connection. Preferably, the damping member is a rubber layer.
[0033] As a second aspect of the present invention, a pipeline mounting bracket assembly is provided. like Figure 1 to Figure 6 As shown, the pipeline installation bracket assembly includes the above-mentioned pipeline installation bracket and a limiter 30 for stopping the rotation of the pipeline installation bracket, and the limiter 30 is in abutment with the pipeline installation bracket. Because the limiting member 30 for restricting the rotation of the pipeline installation bracket is provided, the reliability of the connection between the pipeline installation bracket and the pipeline is ensured, and the pipeline installation bracket can provide stability for the pipeline when the pipeline is subjected to external pressure. The supporting force of the pipeline and the pipeline installation bracket is avoided, and the connection reliability of the two is improved. Since the stopper 30 is in contact with the pipeline installation bracket, when the pipeline installation bracket has a tendency to rotate, the stopper 30 provides a force opposite to the direction of the rotational movement tendency to stop the movement of the pipeline installation bracket .
[0034] like Figure 1 to Figure 6 In this embodiment, the limiter 30 includes a clamp 31 and a limit plate 32, the clamp 31 is clamped with the pipeline, the limit plate 32 is connected with the clamp 31, and the limit plate 32 is clamped with the pipe installation bracket. The open end of the contact portion 11 abuts. The clamp 31 is used to fix the limit plate 32 on the pipeline, and the limit plate 32 is abutted against the open end of the clamping portion 11 to prevent the pipeline installation bracket from rotating.
[0035] like Figure 1 to Figure 6 In this embodiment, the limiting plate 32 has a positioning groove 32a, and the positioning groove 32a is engaged with the fixing structure of the pipeline. Because the positioning groove 32a is clamped with the fixed structure of the pipeline, it is ensured that the limit plate 32 and the pipeline will not move relative to each other, thereby ensuring the positioning accuracy of the limit plate 32 itself, and further ensuring that the limit plate 32 is connected with the limit plate. 32 The positioning accuracy of the installed pipeline mounting brackets prevents the pipeline mounting brackets from rotating on the pipeline.
[0036] like Figure 1 to Figure 6 In the embodiment shown in FIG. 2 , the limiting members 30 are all T-shaped. like Figure 1 to Figure 3 In a preferred embodiment shown, the clamp 31 is arranged at one end of the limit plate 32, the positioning groove 32a is arranged along the length direction of the limit plate 32, and the middle of the clamp 31 is connected to one end of the limit plate 32; in such as 4 to Image 6 In another preferred embodiment shown, one end of the clamp 31 is connected to the middle of the limit plate 32, there are two positioning grooves 32a, and the two positioning grooves 32a are respectively provided at the limit along the length direction of the limit plate 32. both ends of the plate 32 . Of course, the specific structure of the limiting member 30 can be set according to the actual structure of the pipeline.
[0037] Preferably, the limiting member 30 is made of an aluminum alloy material.
[0038]Preferably, there are multiple pipeline installation bracket assemblies, and the multiple pipeline installation bracket assemblies are arranged in sequence along the length direction of the pipeline. Since the pipeline is provided with a plurality of pipeline installation bracket components, the connection area between the pipeline and the position to be installed is increased, the connection reliability of the two is ensured, the stress concentration is reduced, and the use reliability of the pipeline is ensured .
[0039] As a third aspect of the present invention, a microchannel heat exchanger installation system is provided. The microchannel heat exchanger installation system includes a header 40 and a pipeline installation bracket. The pipeline installation bracket is the above-mentioned pipeline installation bracket, and the clamping portion 11 of the pipeline installation bracket is clamped on the header 40 . The microchannel heat exchanger installation system of the present invention further includes fins, flat tubes 50 and end caps. Among them, the collecting tube 40, the flat tube 50 and the end cover form an inner sealing body to ensure the circulating flow of the refrigerant; the fins play an intermediary role and participate in the air of the core body (the core body refers to the general name of the components through which the refrigerant flows) side heat exchange; while the pipeline installation bracket is connected with the shell of the inner and outer machine through screws, so as to ensure that the core body has the characteristics of stable installation and high reliability.
[0040] In the installation system of the micro-channel heat exchanger, due to the excessive load-bearing force of the pipe mounting bracket or the interference of external force, the pipe mounting bracket may rotate around the surface of the header 40 during the brazing process, resulting in the assembly of the pipe mounting bracket. The angle between the surface and the flat tube 50 is deflected, so during assembly, the flat tube 50 needs to be clamped in the positioning groove 32a of the limit plate 32 of the limiter, so that the flat tube 50, the limiter, the tube The road mounting bracket and the header 40 are fixed to each other, thereby improving the reliability of the installation system of the micro-channel heat exchanger.
[0041] like Figure 1 to Figure 3 In the embodiment shown, the perimeter of the clamp 31 is larger than 60% of the outer diameter and perimeter of the header 40 and is symmetrically arranged, and the length of the limiting plate 32 is approximately the width distance of a single or multiple flat tubes 50, and the limit is limited. The width of the position plate 32 is about twice the distance from the flat tube 50 to the open end of the pipeline installation bracket, so as to ensure that the limit plate 32 abuts the pipeline installation bracket, and ensures the reliable connection between the limit member and the header 40 .
[0042] like Figure 4 to Figure 6 In the illustrated embodiment, the circumference of the clamp 31 is greater than 60% of the circumference of the outer diameter of the header 40 and extends unilaterally. The length of the limiting plate 32 is about the width of the flat tube 50. The width is about twice the distance from the flat tube 50 to the open end of the pipeline installation bracket, so as to ensure that the limiter plate 32 abuts the pipeline installation bracket, and ensures the reliable connection between the limiter and the header 40 .
[0043] Of course, the pipeline mounting bracket assembly of the present invention can also be applied to bifurcated pipelines or other pipelines, and has the characteristics of wide adaptability.
[0044] The pipeline installation bracket in the present invention will not damage the structure of the pipeline, thus eliminating the potential safety hazard during the use of the pipeline, prolonging the service life of the pipeline, and ensuring the accuracy and safety of the product. consistency. At the same time, due to the use of a snap connection, the assembly complexity is reduced, and the requirements for the technical level of the staff are reduced.
