Description

Technical Field

[0001] The utility model relates to the technical field of cooling and heating fan pipelines, in particular to a silent cooling and heating fan pipeline. Background Art

[0002] Air coolers and heaters are dual-purpose machines that can keep us cooler in the summer and warmer in the winter. When installing air coolers and heaters, pipes are needed to exchange indoor and outdoor air.

[0003] At present, an existing fan duct (such as patent number: CN2729383Y) discloses a fan duct, which includes a casing, an impeller installed in the casing and fixedly connected to a bearing, a duct connected to an air inlet of the casing, and a damper installed in the duct, wherein a commutator is installed between the air inlet of the casing in the duct and the damper, and in the middle of the commutator is a commutator core installed along the central axis of the duct, and 3-6 fishtail commutator plates are fixed on the commutator core; at least three fixing frames are evenly fixed on the inner wall of the duct, and the other end of the fixing frame is fixedly connected to the commutator. The use of the commutator can comb the non-uniform wind with vortex coming in from the damper into a uniform wind flow parallel to the axial direction and enter the air inlet of the casing, thereby reducing the impact force and turbulent vibration force of the non-uniform wind on the impeller, so that the fan runs smoothly, thereby eliminating vibration, and the equipment runs normally, providing a stable fan for various industrial productions; at the same time, it also saves a lot of expenses caused by replacing dampers, ducts, and casings with greater rigidity and strength.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: in the existing fan duct, the high-speed flow of air produces friction with the duct wall during use, causing the duct to vibrate and generate noise. Because the noise acts on the central nervous system of the brain through the auditory organs, it affects various organs of the body. Therefore, in addition to damaging human hearing, the noise will also cause harm to other systems of the human body. Utility Model Content

Because the noise acts on the central nervous system of the brain through the auditory organs, it affects various organs of the whole body. Therefore, in addition to damaging people's hearing, the noise will also cause harm to other systems of the human body.

The high damping properties of butyl rubber make it a damping layer that weakens vibration waves. The friction between the air and the inner tube generates vibration. After being filtered by the shock-absorbing rubber, the waveform changes and weakens, thereby achieving the purpose of reducing noise. The sound insulation layer on the outer wall of the damping layer can further reduce the noise. The damping layer can reduce the vibration caused by the friction between the air and the inner tube, thereby achieving the effect of reducing the noise caused by the vibration caused by the friction between the air and the inner tube when the air conditioner or heater is in use.

[0021] The embodiment of the present application provides a silent cooling and heating fan duct, which effectively solves the existing fan duct. During use, the high-speed flow of air produces friction with the duct wall, causing the duct to vibrate and generate noise. Because the noise acts on the central nervous system of the brain through the auditory organ, it affects various organs throughout the body. Therefore, in addition to causing damage to human hearing, the noise also causes harm to other systems of the human body. The technical problem is that the bell mouth is installed at the air blowing port of the cooling and heating fan, a connecting ring is put on one end of the bell mouth, and three second bolts are rotated to fix the connecting ring and the bell mouth. Then, the outer tube is cut into the required length according to the required size, and the outer tube is inserted into the inside of the connecting ring. The three first bolts are rotated to fix the connecting ring and the outer tube. If a corner is encountered, another connecting ring can be put on the end of the outer tube, and the three second bolts are rotated to fix it to the end of the outer tube. The corner tube is inserted into one end of the connecting ring, and the three first bolts are rotated. The corner tube can be fixedly connected to the connecting ring. The corner tube is connected with multiple rings of flexible materials and can be bent at any angle. The installation of the pipeline is completed by cutting and bending the outer tube and the corner tube, so that the effect of being able to adapt to various sizes and angles and being conveniently installed is achieved. When the air conditioner and heater are in use, the air flows at a high speed inside the inner tube, and the air and the inner tube produce friction. The damping layer on the outer wall of the inner tube is composed of a damping sheet. The damping sheet is a shock-absorbing rubber material composed of butyl rubber and metal aluminum foil. The high damping property of butyl rubber makes it a damping layer for weakening vibration waves. The friction between the air and the inner tube produces vibration. After the shock-absorbing filtration of the shock-absorbing rubber, the waveform changes and weakens, thereby achieving the purpose of reducing noise. The sound insulation layer on the outer wall of the damping layer can further reduce the noise. The damping layer can reduce the vibration caused by the friction between the air and the inner tube, thereby achieving the effect of reducing the noise caused by the vibration caused by the friction between the air and the inner tube when the air conditioner and heater are in use.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that an existing fan duct vibrates and generates noise due to friction between the high-speed flow of air and the duct wall during use. Since the noise acts on the central nervous system of the brain through the auditory organ, it affects various organs of the whole body. Therefore, in addition to damaging human hearing, the noise also causes harm to other systems of the human body. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a silent cooling and heating fan duct, comprising an outer tube 1, an inner wall of the outer tube 1 is fixedly installed with a sound insulation layer 6, an inner wall of the sound insulation layer 6 is fixedly installed with a damping layer 7, an inner wall of the damping layer 7 is fixedly installed with an inner tube 8, connecting rings 2 are fixedly installed at both ends of the outer tube 1, a bell mouth 3 is fixedly installed at the side end of the connecting ring 2 located on the opposite side of the outer tube 1, a corner tube 5 is fixedly installed at the side end of the connecting ring 2 located on the opposite side of the bell mouth 3, three first bolts 4 are evenly fixedly installed on the side end of the connecting ring 2, and three second bolts 9 are evenly fixedly installed on the side end of the connecting ring 2 located on the opposite side of the first bolts 4.

[0025] Working principle:

[0026] The first step is to install the bell mouth 3 on the air outlet of the air conditioner and heater, put the connecting ring 2 on one end of the bell mouth 3, rotate the three second bolts 9 to fix the connecting ring 2 and the bell mouth 3, and then cut the outer tube 1 into the required length according to the required size, insert the outer tube 1 into the inside of the connecting ring 2, rotate the three first bolts 4 to fix the connecting ring 2 and the outer tube 1. If a corner is encountered, another connecting ring 2 can be put on the end of the outer tube 1, and the three second bolts 9 can be rotated to fix it to the end of the outer tube 1. Insert a corner tube 5 at one end of the connecting ring 2, and then rotate the three first bolts 4 to fix the corner tube 5 to the connecting ring 2. The corner tube 5 is connected by multiple rings of flexible materials and can be bent at any angle. The installation of the pipeline is completed by cutting and bending the outer tube 1 and the corner tube 5, achieving the effect of being able to adapt to a variety of sizes and angles and being able to be easily installed.

[0027] In the second step, when the air conditioner and heater are in use, the air flows at a high speed inside the inner tube 8, and the air and the inner tube 8 produce friction. The damping layer 7 on the outer wall of the inner tube 8 is composed of a damping sheet. The damping sheet is a shock-absorbing rubber material composed of butyl rubber and metal aluminum foil. The high damping property of butyl rubber makes it a damping layer 7 that weakens vibration waves. The air and the inner tube 8 rub against each other to produce vibration. After being filtered by the shock-absorbing rubber, the waveform changes and weakens, thereby achieving the purpose of reducing noise. The sound insulation layer 6 on the outer wall of the damping layer 7 can further reduce the noise. The damping layer 7 can reduce the vibration caused by the friction between the air and the inner tube 8, thereby achieving the effect of reducing the noise caused by the vibration caused by the friction between the air and the inner tube 8 when the air conditioner and heater are in use.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
