[0023] First of all, it needs to be stated that the technical solutions of the embodiments of the present application are clearly and completely described. The described embodiments are part of the embodiments of the present application, rather than limitations of the present utility model. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present application.

[0024] In the description of the present invention, it is necessary to understand that the orientation or position relationship indicated by the terms "up", "down", "left", "right", "inside", "outside", "axial" or "radial" is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention, and is not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0025] like Figure 1 and Figure 2 As shown, in the embodiment of the present scheme, the steel pipe support structure includes a water pipe 1, a support member 3, a fixing member 2 and a base plate 4, the support member 3 is installed on the base plate 4 and supports the water pipe 1, the fixing member 2 fixes the water pipe 1 on the support member 3, the fixing member 2 includes an upper shock-absorbing block 6, a lower shock-absorbing block 7 and a clamp 5, the upper shock-absorbing block 6 is arranged on the upper part of the water pipe 1, the lower shock-absorbing block 7 is arranged between the water pipe 1 and the support member 3, the lower end surface of the upper shock-absorbing block 6 is provided with a first groove 61, the upper end surface of the lower shock-absorbing block 7 is provided with a second groove 71, the first groove 61 and the second groove 71 are respectively in contact with the surface of the water pipe 1, the clamp 5 is provided on the outer surfaces of the upper shock-absorbing block 6 and the lower shock-absorbing block 7, the upper shock-absorbing block 6 and the lower shock-absorbing block 7 are clamped, so that the first groove 61 and the second groove 71 are respectively in close contact with the water pipe 1, and the lower end of the clamp 5 is fixedly connected to the support member 3.

[0026] The water pipe 1 includes an inlet pipe and an outlet pipe, and the hot medium fluid or the cold medium fluid is connected to the heat exchanger through the inlet pipe, and the temperature of the medium fluid is adjusted by the heat exchanger, and discharged from the heat exchanger through the outlet pipe and transported to the indoor unit. The water pipe 1 is supported by a support member 3 installed on the bottom plate 4, and the fixing member 2 includes an upper damping block 6, a lower damping block 7 and a clamp 5. The lower end surface of the upper damping block 6 is provided with a first groove 61, and the upper end of the lower damping block 7 is provided with a second groove 71. The cross-sections of the first groove 61 and the second groove 71 are arc-shaped. The upper damping block 6 and the lower damping block 7 can be designed as a contact type or a non-contact type. For example, when the upper damping block 6 and the lower damping block 7 are in contact, the contact position can be at any position around the circular cross-section of the water pipe 1. When the upper damping block 6 and the lower damping block 7 are not in contact, the upper damping block 6 and the lower damping block 7 only wrap a part of the circular cross-section of the water pipe 1. The cross section of the first groove 61 and the second groove 71 may not be an arc shape. A part of the cross section of the first groove 61 and the second groove 71 contacts the surface of the water pipe 1, and another part forms a cavity with the surface of the water pipe 1, thereby increasing the deformation space of the upper shock absorbing block 6 and the lower shock absorbing block 7. In addition, the clamp 5 wraps the outer surface of the upper shock absorbing block 6 and the lower shock absorbing block 7, and is fixedly installed on the support 3, which can be fixed by welding or screws, or the clamp 5 is a circular clamp, which wraps the water pipe 1 around, and the clamp 5 passes through the support 3 and is fastened by nuts, or the clamp 5 does not pass through the support 3, and screw holes are opened on the clamp 5 and the support 3, and bolts pass through the screw holes of the clamp 5 and the support 3, and are fixedly connected by nuts.

[0027] like Figure 3 As shown, in the embodiment of the present scheme, the lower end face of the upper shock-absorbing block 6 and the upper end face of the lower shock-absorbing block 7 are connected by a snap-fit ​​structure, a boss is set on the lower end face of the upper shock-absorbing block 6, and a corresponding slot is set on the upper end face of the lower shock-absorbing block 7. When the upper shock-absorbing block 6 and the lower shock-absorbing block 7 are in contact with the surface of the water pipe 1, the boss is installed and matched with the slot. When the lower end face of the upper shock-absorbing block 6 contacts the upper end face of the lower shock-absorbing block 7, the water pipe 1 is wrapped and protected, and the upper shock-absorbing block 6 and the lower shock-absorbing block 7 have a limiting effect to prevent misalignment and offset; the boss is installed and matched with the slot, and the lower end of the upper shock-absorbing block 6 When the surface is not in contact with the upper end surface of the lower shock absorbing block 7, a small cavity is formed between the lower end surface of the upper shock absorbing block 6 and the upper end surface of the lower shock absorbing block 7, which increases the deformation space between the upper shock absorbing block 6 and the lower shock absorbing block 7, and improves the vibration reduction effect of the upper shock absorbing block 6 and the lower shock absorbing block 7. In addition, the boss can be designed as a conical boss with a certain slope, and the groove is also designed as a corresponding conical groove with a certain slope, so that the upper shock absorbing block 6 and the lower shock absorbing block 7 can be limited, and the water pipe 1 can be wrapped and protected, improving the vibration reduction effect of the upper shock absorbing block 6 and the lower shock absorbing block 7. Similarly, the lower end surface of the upper shock absorbing block 6 can be provided with a groove, and the corresponding boss can be provided on the upper end surface of the lower shock absorbing block 7, which are all within the protection scope of this solution.

[0028] like Figure 3 As shown, in the embodiment of the present scheme, the cross-sections of the first groove 61 and the second groove 71 are semicircular, and the lower end surface of the upper damping block 6 contacts the upper end surface of the lower damping block 7. The first groove 61 and the second groove 71 are both designed with a semicircular cross-section, which is convenient for installation and replacement, suitable for production, and one-mold molding, ensuring the interchangeability of the upper damping block 61 and the lower damping block 71, which can not only ensure product quality, but also improve labor productivity and reduce costs. No repair and adjustment are required before assembly, and the predetermined and use requirements can be met after assembly.

[0029] like Figure 3 As shown, in the embodiment of the present scheme, the clamp 5 is set to be arched, and the inside of the clamp 5 arch contacts the upper damping block 6 and the lower damping block 7. The two bottom ends of the clamp 5 arch are transversely bent to form two bent plates 51, and the bent plates 51 are provided with bolt holes. The bent plates 51 of the clamp 5 are fixedly connected to the support member 3 by bolts. The shape of the clamp 5 is not limited, and can be adaptively changed following the upper damping block 6 and the lower damping block 7. The inside of the clamp 5 wraps the outer surface of the upper damping block 6 and the lower damping block 7, and the upper damping block 6 and the lower damping block 7 are clamped to the outer surface of the water pipe 1, and are fixedly connected to the support member 3 by bolts through the bolt holes of the two bent plates 51. The two bent plates 51 may contact the support member 3 or may not contact the support member 3. When the two bending plates 51 are not in contact with the support member 3, after the steel pipe support structure has been used for a long time, the upper shock-absorbing block 6 and the lower shock-absorbing block 7 will produce a certain deformation. In order to save costs, they do not need to be replaced. Just tighten the bolts connecting the two bending plates 51 and the support member 3 again, so that the two bending plates 51 continue to move downward, and tighten the upper shock-absorbing block 6 and the lower shock-absorbing block 7 again, so that the upper shock-absorbing block 6 and the lower shock-absorbing block 7 are close to the water pipe 1, thereby improving the service life of the steel pipe support structure.

[0030] like Figure 1 and Figure 4As shown, in the embodiment of the present scheme, the end face of the water pipe 1 is provided with a flange 8, and a water pipe clearance hole 93 is provided on the panel 9 of the unit. The diameter of the water pipe clearance hole 93 is larger than the diameter of the flange 8. The flange 8 passes through the water pipe clearance hole 93 to connect with the system outside the unit, and the gap between the water pipe 1 and the panel 9 is sealed by a sealing plate 10. The sealing plate 10 is divided into two pieces, and the shape is a semicircular ring. The spliced ​​sealing plate 10 is sleeved on the outer surface of the water pipe 1 and fixed on the panel 9 by riveting. The sealing plate 10 is set to be symmetrical, and the front and back sides can be used interchangeably. The sealing plates 10 are spliced ​​and matched together to clamp the water pipe 1 to eliminate the hole gap between the panel 9 and the water pipe 1. In addition to the riveting fixation method, screw holes can also be opened on the sealing plate 10 and the panel 9, and screws are passed through the screw holes on the sealing plate 10 and the panel 9, and the nuts are tightened to achieve fixation. In order to ensure the heat exchange effect of the chassis and prevent the internal components of the chassis from overheating and damaging the components, the panel 9 is provided with several long ventilation holes 92. The ventilation holes 92 can also be set as round or square, and the long strip shape is one of the preferred methods. In order to ensure the strength requirements of the panel 9 and prevent deformation during disassembly and assembly, which affects assembly and appearance, a reinforcing plate 91 is welded on the back of the panel 9.
