Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to a copper tube fixing structure of an air conditioner unit. Background Art

[0002] In the air-conditioning industry, especially in the internal design of large units such as modular units and chillers, the fixation of copper tubes is a very critical link. During the operation of the air-conditioning system, the compressor, fan and other components will vibrate, and these vibrations will be transmitted to the copper tubes. If the copper tubes are not effectively fixed, long-term vibrations will cause the interface between the copper tubes and the pipeline to loosen, and even cause refrigerant leakage. In addition, copper tubes are important channels for refrigerant circulation. If the copper tubes are arranged loosely, especially in elbows, joints and other parts, unnecessary resistance may be generated when the refrigerant flows through, affecting the refrigeration efficiency and system performance. Therefore, fixing the copper tubes can ensure a smooth refrigerant flow path and maintain the efficient operation of the system. At present, the fixation of copper tubes is often rooted from the base of the unit to install a support structure, usually a pre-designed support frame or base plate with fixed points or reserved holes on it, which is used to directly fix the copper tubes to the fixed points or reserved holes, so as to fix and install the copper tubes. However, some units have limited space in the overall unit frame, and when the copper tubes are densely arranged, it is impossible to root and install a support structure from the base. How to effectively utilize the unit space to fix the copper tubes has become a difficult problem. Utility Model Content

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The copper tube fixing structure of the air-conditioning unit includes a middle frame cross beam, a middle frame support beam, a copper tube fixing plate, a clamp and a connecting plate. The middle frame support beam is horizontally arranged and vertically connected to the middle frame cross beam. A connecting plate is fixedly provided at one end of the copper tube fixing plate in the length direction. The upper surface of the connecting plate is affixed and connected to the lower surface of the middle frame support beam.

[0007] Furthermore, the middle frame support beam and the middle frame cross beam are connected by bolts.

[0008] Furthermore, the upper surface of the connecting plate is in contact with the lower surface of the middle frame support beam and is connected by bolts.

[0009] Furthermore, the copper tube fixing plate is a U-shaped steel, and one side of the lower surface of the connecting plate is fixedly connected to one side of the open end of the copper tube fixing plate.

[0010] Furthermore, at least two connecting plates are provided, and connecting plates are provided on both sides of the open end of the copper tube fixing plate.

[0011] Furthermore, it includes a triangular reinforcement edge, which is a vertically arranged triangular plate, and the connecting plate is an outward turned edge on the side of the open end of the copper tube fixing plate. The horizontal side of the triangular reinforcement edge is fixedly connected to the lower surface of the connecting plate, and the vertical side of the triangular reinforcement edge is fixedly connected to the side wall of the copper tube fixing plate. One surface of the triangular reinforcement edge is aligned with the edge of one side wall of the copper tube fixing plate.

[0012] Furthermore, there are a plurality of triangular reinforcement edges, and at least one opposite triangular reinforcement edge is provided on one side of the open end of the copper tube fixing plate.

[0013] Furthermore, it includes a reinforcing edge, which is an extension of one side edge of the triangular reinforcement edge fixedly connected to the side wall of the copper tube fixing plate, and the lower end of the reinforcing edge extends along the vertical direction of the copper tube fixing plate to the lower half of the copper tube fixing plate.

[0014] The beneficial effects of the utility model are:

The copper tube fixing plate can be fixed at any position on the cross beam, and the copper tube is fixed to the copper tube fixing plate by a clamp, realizing the effective use of the unit space to fix the copper tube.

[0016] The setting of the protective rubber pad not only reduces the wear caused by direct contact between the copper tube and the clamp, but also effectively isolates it from corrosion from the external environment, thus extending the service life of the copper tube.

[0028] The copper tube fixing structure of the air-conditioning unit includes a middle frame cross beam, a middle frame support beam 1, a copper tube fixing plate 2, a clamp 3 and a connecting plate 5. The middle frame support beam 1 is horizontally arranged and vertically connected to the middle frame cross beam. A connecting plate 5 is fixedly arranged at one end of the copper tube fixing plate 2 in the length direction. The upper surface of the connecting plate 5 is affixed and connected to the lower surface of the middle frame support beam 1. A clamp 3 is provided on the side of one end of the copper tube fixing plate 2 away from the connecting plate 5.

[0029] The utility model uses the middle frame crossbeam as the rooting position of the copper tube fixing structure of the air-conditioning unit. Since there is space between the middle frame of the unit and the copper tube layout, the crossbeam can be at any position in the unit frame, so that the copper tube at any position can be flexibly fixed. The flexibility is greater than the method of rooting the support plate on the base, and the situation that some units have limited overall unit frame space and the copper tube layout is dense, and it is impossible to root and install a supporting structure from the base is avoided, thereby realizing effective use of the unit space to fix the copper tube.

[0030] A protective rubber pad 4 is provided on the inner wall of the clamp 3. Since the copper tube often has the function of transferring heat, the protective rubber pad 4 is designed on the inner wall of the clamp 3 to further protect the copper tube and also to keep it warm. At this time, the outer peripheral side of the copper tube is in contact with the protective rubber pad 4.

[0031] The middle frame support beam 1 is connected to the middle frame cross beam by bolts.

[0032] The connecting plate 5 is connected to the middle frame support beam 1 by bolts.

[0033] The middle frame support beam 1 is mainly responsible for taking root on the middle frame cross beam. In this solution, welding can also be used for connection. However, considering the need for maintenance and replacement of copper tubes, a detachable bolt connection is preferred. The same is true for the connecting plate 5, so that the structure is easy to assemble and disassemble while ensuring the connection strength, which is convenient for daily maintenance and inspection.

[0034] The copper tube fixing plate 2 is a U-shaped steel, and one side of the lower surface of the connecting plate 5 is fixedly connected to one side of the open end of the copper tube fixing plate 2 .

[0035] In this solution, the copper tube fixing plate 2 can also be made of angle steel or flat plate, but from the perspective of saving costs and maintaining strength requirements, U-shaped steel is preferably used, and its open part can be provided with a flange to connect to the middle frame support beam 1 or other components, which is more scientific and convenient.

[0036] There are at least two connecting plates 5 , and connecting plates 5 are provided on both sides of the open end of the copper tube fixing plate 2 .

[0037] Connecting plates 5 are provided on both sides of the open end of the copper tube fixing plate 2 to further enhance the strength and balance the force.

[0038] It includes a triangular reinforcement edge 6, which is a vertically arranged triangular plate. The connecting plate 5 is an outward turned edge on the side of the open end of the copper tube fixing plate 2. The horizontal side of the triangular reinforcement edge 6 is fixedly connected to the lower surface of the connecting plate 5, and the vertical side of the triangular reinforcement edge 6 is fixedly connected to the side wall of the copper tube fixing plate 2. One surface of the triangular reinforcement edge 6 is aligned with the edge of one side wall of the copper tube fixing plate 2.

[0039] The introduction of triangular reinforcement edges, especially around the open end of the copper tube fixing plate, significantly enhances the local bending and torsion resistance, especially when the copper tube is heavy or impacted by external forces, which can effectively prevent structural deformation and ensure the safe operation of the copper tube fixing structure of the air-conditioning unit.

[0040] There are several triangular reinforcing edges 6 , and at least two opposite triangular reinforcing edges 6 are arranged on one side of the open end of the copper tube fixing plate 2 , which further amplifies the function of the triangular reinforcing edges 6 .

[0041] It includes a reinforcing edge 7, which is an extension of one side edge of the triangular reinforcement edge 6 fixedly connected to the side wall of the copper tube fixing plate 2, and the lower end of the reinforcing edge 7 extends along the vertical direction of the copper tube fixing plate 2 to the lower half of the copper tube fixing plate 2.

[0042] The outer shape of the reinforcement edge can be any shape as long as it can achieve the anti-bending and anti-torsion effects. For those skilled in the art, the present invention can have various modifications and changes.

[0043] The preparation process and surface treatment method of the copper tube fixing structure of the air conditioner provided by the utility model are not limited. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
