Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, and in particular to a water chiller protective cover with a noise reduction function. Background Art

[0002] A water chiller is a cooling water device that can provide constant temperature, constant pressure and constant flow. Water chillers are divided into water-cooled chillers and air-cooled chillers according to the refrigeration form. The water chiller uses a shell and tube evaporator to exchange heat between water and refrigerant. After the refrigerant system absorbs the heat load in the water, it lowers the water temperature to produce cold water, which is then contacted through a compressor or cooling water and conducts the heat to the outside world, causing the heat to be dissipated to the outside world.

[0003] When the chiller is working, in order to prevent the chiller from being disturbed by the external environment, a chiller protective cover will be installed on the outside of the chiller. The chiller protective cover can protect the chiller when working outdoors in harsh conditions, isolate the chiller from interference from environmental factors, prevent environmental factors from causing damage to the chiller, effectively extend the service life of the chiller in harsh environments, and prevent a large amount of dust from entering the chiller and affecting the chiller's cold water manufacturing efficiency.

[0004] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the chiller is working, it will generate high-frequency jitter during operation and thus generate strong noise. If the chiller is used in laboratories and other places with strict requirements on quietness, it is easy to cause noise pollution to quiet places such as laboratories. Although the chiller protective cover can protect the chiller, it cannot isolate the noise generated by the chiller when it is working, and its function is relatively single. Utility Model Content

[0005] The utility model aims to provide a chiller protective cover with noise reduction function, which can absorb vibration and reduce noise, in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a chiller protective cover with noise reduction function, comprising a protective cover body and a water inlet pipe penetrating the outer wall of the protective cover body, the protective cover body comprising a soundproof outer shell and a bottom plate arranged at the bottom of the inner wall of the soundproof outer shell, a plurality of elastic brackets are fixed on the bottom plate, a partition support plate is provided on the elastic bracket, and a fitting shock-absorbing layer is also provided on the inner wall of the soundproof outer shell. After the chiller is installed, when shaking noise is generated, the partition support plate cooperates with the elastic bracket to absorb the up and down shaking and part of the lateral shaking of the chiller during operation, and at the same time cooperates with the fitting shock-absorbing layer to limit the shaking of the chiller and absorb it again.

[0007] A further improvement is that a movable chassis is also provided at the bottom of the protective cover body.

[0008] A further improvement is that: the front side of the protective cover body is also movably engaged with an opening and closing door.

[0009] A further improvement is that the fitted shock-absorbing layer includes an outer shell fixedly connected to the inner wall of the sound insulation outer shell and a side expansion plate arranged in the outer shell, an elastic bracket is provided between the side expansion plate and the outer shell, and an elastic plate is slidably connected to the inner wall of the side expansion plate.

[0010] A further improvement is that: an arc-shaped elastic sheet is also embedded on the side expansion plate.

[0011] A further improvement is that: an impact absorbing block is provided through the elastic plate.

[0012] A further improvement is that the impact absorbing block includes an elastic ball penetrating the elastic plate and a recovery frame arranged in the elastic ball, a vent hole penetrating the elastic ball is arranged on the top of the elastic ball, and a freely movable blocking ball is arranged on the inner wall of the recovery frame.

[0013] A further improvement is that a hemispherical contact block made of silicone is also provided at the bottom of the elastic ball.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: after the utility model is installed in the chiller, the vibration generated during the operation of the chiller can be absorbed by bonding the shock-absorbing layer and the elastic bracket with the partition support plate, thereby avoiding the noise generated by the operation vibration, and at the same time protecting the chiller, with richer functions.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a chiller protective cover with noise reduction function, including a protective cover body 2 and a water inlet pipe 3 penetrating the outer wall of the protective cover body 2, the protective cover body 2 includes a soundproof shell 21 and a bottom plate 23 arranged at the bottom of the inner wall of the soundproof shell 21, a plurality of elastic brackets 24 are fixedly arranged on the bottom plate 23, and a partition support plate 25 is arranged on the elastic bracket 24, and the inner wall of the soundproof shell 21 is also provided with a bonding shock-absorbing layer 22, and the bonding shock-absorbing layer 22 includes a soundproof shell 21 and a soundproof shell 21. The outer shell 31 is fixedly connected to the inner wall, and the side expansion plate 36 is arranged in the outer shell 31. An elastic bracket 34 is arranged between the side expansion plate 36 and the outer shell 31. The inner wall of the side expansion plate 36 is slidably connected with an elastic plate 32. After the chiller is installed, when the shaking noise is generated, the partition support plate 25 cooperates with the elastic bracket 24 to absorb the up and down shaking and part of the lateral shaking of the chiller during operation, and at the same time cooperates with the bonding shock-absorbing layer 22 to limit the shaking of the chiller and absorb it again. When in use, the chiller is installed in the protective cover body 2 and The water inlet pipe 3 is connected to the water inlet of the chiller and is connected to the water inlet equipment outside. At this time, the protective cover body 2 can be used to protect the chiller. When the chiller is working, it will vibrate and produce noise. At this time, the up and down vibrations and part of the lateral vibrations generated by the chiller will be deformed and absorbed by the elastic bracket 34, and the deformation of the elastic bracket 34 will not be restricted by the partition support plate 25. At the same time, when the chiller is installed, it is inserted into the fitting shock-absorbing layer 22, and the side expansion plate 36 is expanded and squeezes the elastic bracket 34 to produce elastic The side expansion plates 36 on both sides squeeze the water chiller and output elastic force to firmly lock it, and absorb lateral vibration through the elastic bracket 34, thereby preventing the lateral vibration of the water chiller from generating noise during operation. At the same time, the elastic plate 32 arranged on the inner wall of the side expansion plate 36 further absorbs the vibration in the up and down directions, thereby fully absorbing and slowly releasing the up and down and lateral vibration generated by the operation of the water chiller, avoiding strong noise caused by the vibration, and the soundproof shell 21 made of soundproof material further isolates the sound and protects the water chiller at the same time;

[0022] The bottom of the protective cover body 2 is also provided with a movable chassis 1, which is conducive to making the protective cover movable and more flexible to use;

[0023] The front of the protective cover body 2 is also movably engaged with an opening and closing door 4, which is conducive to making the installation and removal of the chiller more convenient and quick;

[0024] The side expansion plate 36 is also embedded with an arc-shaped elastic sheet 35, which is conducive to absorbing the pressure after the side expansion plate 36 is squeezed and converting it into elastic force, thereby better fixing the chiller through the elastic force, and enhancing the absorption effect of the side expansion plate 36 on lateral shaking;

[0025] The elastic plate 32 is provided with an impact absorbing block 33, which includes an elastic ball 42 provided on the elastic plate 32 and a recovery frame 43 provided in the elastic ball 42. The top of the elastic ball 42 is provided with an exhaust hole 44 which penetrates the elastic ball 42. The inner wall of the recovery frame 43 is provided with a freely movable blocking ball 45. After the elastic plate 32 contacts the chiller, when it shakes up and down, the chiller squeezes the elastic ball 42 to deform its inner cavity, thereby converting the impact force generated by the shaking into a squeezing force on the gas, thereby allowing the gas to quickly pass through the recovery frame 43 and be discharged from the exhaust hole 44, and cooperate with the blocking ball 45 to block a part of the gap between the recovery frames 43 so that the gas will not lose support force too quickly, thereby ensuring the supporting and fixing effect while quickly absorbing the shaking impact, locking the chiller and reducing the noise caused by the shaking;

[0026] A hemispherical contact block 41 made of silicone is also provided at the bottom of the elastic ball 42, which is beneficial to prevent sliding with the surface of the chiller while ensuring the deformation and vibration absorption performance, thereby achieving a better vibration impact transmission effect.

[0027] Working principle of the utility model: When the utility model is used, the water chiller is installed in the protective cover body 2, and the water inlet pipe 3 is connected to the water inlet of the water chiller and connected to the water inlet equipment outside. At this time, the water chiller can be protected by the protective cover body 2. When the water chiller is working, it will vibrate and produce noise. At this time, the up and down vibrations and part of the lateral vibrations generated by the water chiller will be deformed and absorbed by the elastic bracket 34, and the deformation of the elastic bracket 34 will not be restricted by the partition support plate 25. At the same time, when the water chiller is installed, it is stuck in the fitting shock-absorbing layer 22, and the side The expansion plate 36 expands and squeezes the elastic bracket 34 to generate elastic force, and outputs elastic force so that the chiller is squeezed by the side expansion plates 36 on both sides and is firmly locked. The lateral vibration is absorbed by the elastic bracket 34, thereby preventing the lateral vibration during the operation of the chiller from generating noise. At the same time, the elastic plate 32 arranged on the inner wall of the side expansion plate 36 further absorbs the vibration in the up and down directions, thereby fully absorbing and releasing the up and down and lateral vibration generated during the operation of the chiller, avoiding strong noise due to vibration, and the sound insulation shell 21 made of sound insulation material further isolates the sound and protects the chiller at the same time.
