Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fixing equipment, and in particular relates to a thermal break fixing device for an extra-long copper pipe of an air conditioner. Background Art
[0002] With the increasing application scenarios of air-conditioning multi-split systems, the continuous improvement of equipment compressor performance, and the addition of oil separators to the equipment, the length of the copper pipe connection has continued to increase, and the spacing of the oil return bend has increased. Under such circumstances, the copper pipe risers of many projects have also appeared to have super-long connection pipes (single pipe exceeds 30 meters). Due to the increase in the system, the diameter and length of the riser are increasing, so the pipe fixing of super-long risers has become a technical difficulty. The existing copper pipe riser fixing method is mostly to use a U-shaped clamp in the middle of the copper pipe, clamp it on the rubber-plastic insulation on the outside of the copper pipe, and use a bracket to hold the horizontal pipe at the top of the riser and the elbow at the bottom.
[0003] The above fixing method has the following disadvantages:
[0004] If the U-shaped clamp is not tight, it cannot bear the weight of the longitudinal pipe.
[0005] The tightening of the U-shaped clamp can easily cause the copper tube to deform, affecting the flow of refrigerant in the tube, causing system failure and increasing energy consumption;
[0006] When the U-shaped clamp is tightened, it is easy to squeeze the rubber and plastic insulation, causing it to be severely deformed or even damaged, losing its insulation function and causing condensate leakage. In addition, because it is in the middle of the pipe shaft, the space is small and personnel cannot enter, making the leakage point impossible to repair.
[0007] At the same time, due to the phenomenon of thermal expansion and contraction of the copper pipe during system operation, the top elbow is easily cracked and detached due to the stress and gravity of the pipe;
[0008] The bottom elbow is easily deformed due to the influence of the gravity of the pipeline, which affects the flow of refrigerant in the pipe, causing system failure and increased energy consumption.
[0009] Therefore, it is necessary to develop a new type of thermal break fixing device for super-long air-conditioning copper pipes. Utility Model Content
[0010] The utility model aims to solve the problems of the prior art and provides a thermal break fixing device for an extra-long copper pipe of an air conditioner.
[0011] In order to solve the technical problem, the technical solution of the utility model is: a thermal break fixing device for extra-long air-conditioning copper pipes, comprising a short copper pipe, a PPR protective pipe, a galvanized U-shaped pipe clamp and an angle iron bracket, the short copper pipe and the PPR protective pipe are respectively mounted on the extra-long air-conditioning copper pipe, the short copper pipe is fixedly connected to the extra-long air-conditioning copper pipe, the bottom of the short copper pipe is interference fit with the PPR protective pipe, the galvanized U-shaped pipe clamp fixes the PPR protective pipe on the angle iron bracket, and the angle iron bracket is fixed to the wall of the pipe well.
[0012] Preferably, the top of the short copper tube is welded to the extra-long air-conditioning copper tube, and the bottom of the short copper tube is interference fit with the PPR protective tube.
[0013] Preferably, a plurality of mounting holes are provided on the angle iron bracket, and two ends of the galvanized U-shaped pipe clamp pass through the mounting holes respectively and are fixed by bolts.
[0014] Preferably, the inner diameter of the short copper tube is 0.5-1 cm larger than the outer diameter of the extra-long air-conditioning copper tube, and the outer diameter of the bottom of the short copper tube is interference fit with the inner diameter of the PPR protective tube.
[0015] Preferably, the height of the short copper tube is 3-5 cm, the height of the PPR protection tube is 5-7 cm, and the height of the angle iron bracket is 4-5 cm.
[0016] Preferably, the short copper tube, the PPR protective tube and the extra-long air-conditioning copper tube are coaxial, and the axis of the short copper tube is perpendicular to the straight line where the length of the angle iron bracket lies.
[0017] Compared with the prior art, the advantages of the utility model are:
[0018] (1) The utility model provides a thermal break fixing device for an extra-long air-conditioning copper tube. A short copper tube is welded to the outside of the extra-long air-conditioning copper tube. The bottom of the short copper tube is interference-fitted with the PPR protective tube, so that the gravity of the extra-long air-conditioning copper tube can be evenly distributed on the PPR protective tube. The short copper tube is then fastened to an angle iron bracket through a galvanized U-shaped pipe clamp. The angle iron bracket is fixed to the wall of the pipe well, so that the force of the extra-long air-conditioning copper tube is carried at various places on the wall of the pipe well.
[0019] (2) The utility model fastens the PPR protective pipe to the angle iron bracket through the galvanized U-shaped pipe clamp. The PPR protective pipe is used in the contact with the galvanized U-shaped pipe clamp. It is a non-metallic pipe, which avoids the cold bridge between the metal bracket and the extra-long air-conditioning copper pipe;
[0020] (3) The galvanized U-shaped pipe clamp of the utility model is subjected to force on the PPR protective pipe. Since the PPR protective pipe has a certain strength, it can also protect the extra-long air-conditioning copper pipe inside it from deformation due to force;
[0021] (4) The short copper tube of the utility model and the PPR protective tube are interference fit. Since the longitudinal force is in the same direction, the PPR protective tube can act as a sliding bracket when the short copper tube is deformed by thermal expansion and contraction, effectively avoiding the deformation stress accumulation of the short copper tube and the super-long air-conditioning copper tube;
[0022] (5) The utility model has a simple structure, is easy to operate and implement, and all accessories are made of commonly used materials on the market. Due to the small amount used, whether it is a short copper tube or a PPR protective tube, the remaining waste materials on the construction site can be used, and the cost is low.

[0042] The working principle of the utility model is as follows:

[0044] The utility model provides a thermal break fixing device for an extra-long copper tube of an air conditioner. A short copper tube is welded to the outside of the extra-long copper tube of the air conditioner. The bottom of the short copper tube is interference fit with a PPR protective tube, so that the gravity of the extra-long copper tube of the air conditioner can be evenly distributed on the PPR protective tube. The short copper tube is then fastened to an angle iron bracket through a galvanized U-shaped pipe clamp.

[0048] The utility model has the advantages of simple structure, easy operation and easy realization; all accessories are made of commonly used materials on the market; due to the small amount used, both short copper tubes and PPR protective tubes and remaining waste materials on the construction site can be used, and the cost is low.
[0049] Through many on-site practices and scheme demonstrations, the technical personnel of the present utility model proposed a thermal break fixing device for extra-long air-conditioning copper pipes in combination with the actual on-site conditions. A short copper pipe 1 with a length of 3~4cm, which is one specification larger than the actual extra-long air-conditioning copper pipe 5, is selected and installed at the position where the additional fixing bracket is needed. It should generally be 0.5~1cm higher than the horizontal height of the wall angle iron bracket 4. It is fixed to the extra-long air-conditioning copper tube 5 by welding, and a 5-7cm long PPR protective tube 2 is selected below it. The pipe diameter should be larger than the actual extra-long air-conditioning copper tube 5 so that it can be smoothly inserted into the extra-long air-conditioning copper tube 5. If the size is too large, it can be broken vertically, and the broken opening can be trimmed so that it can wrap the extra-long air-conditioning copper tube 5 more tightly. Move this section of the pipe to the bottom of the short copper tube 1 that was previously welded and fixed, so that the lateral interfaces of the two sections of the pipe are closely connected.
