Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to a falling film water chiller. Background Art

[0002] In the refrigeration industry, there are two types of chillers: air-cooled chillers and water-cooled chillers. According to the compressor, they are divided into screw chillers, scroll chillers, and centrifugal chillers. In terms of temperature control, they are divided into low-temperature industrial chillers and normal temperature chillers. The temperature of normal temperature units is generally controlled within the range of 0 degrees to 35 degrees, and the temperature of low-temperature units is generally controlled within the range of 0 degrees to -100 degrees.

[0003] The existing falling film chiller is usually directly fixed at the required position. The falling film chiller will generate large vibration during use and the vibration will be accompanied by noise. The existing method is to directly place the falling film chiller in the box, which may reduce the noise, but the transmitted noise is still large, and due to the limited space inside the box, it is not conducive to the heat dissipation of the falling film chiller. Therefore, the utility model designs a falling film chiller to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides an embodiment: a falling film chiller, comprising: a base 1, a noise reduction component 4 is arranged on the top of the base 1, a support base 2 is fixedly installed between the tops of four noise reduction components 4, and the setting of the noise reduction component 4 can slow down the vibration of the falling film chiller body 3 during operation, thereby reducing the noise generated by the vibration, which is beneficial to energy saving and environmental protection, and the falling film chiller body 3 is fixedly installed on the top of the support base 2, and sound insulation boards 5 are fixedly installed around the top of the base 1, and the four sound insulation boards 5 are mutually enclosed and spliced ​​to form a rectangular box, and a support plate 6 is fixedly installed between the tops of the four sound insulation boards 5.

[0020] See also Figure 1-2 In the embodiment of the utility model: the noise reduction component 4 includes: a reinforcing rib cylinder 401, the reinforcing rib cylinder 401 is fixedly installed on the top of the base 1, a rubber ring 402 is fixedly installed on the top of the reinforcing rib cylinder 401, and a reinforcing rib sleeve 403 is fixedly installed on the top of the rubber ring 402, the reinforcing rib sleeve 403 is sleeved on the upper end of the reinforcing rib cylinder 401, the top of the reinforcing rib sleeve 403 is fixedly installed with the bottom of the support seat 2, a damping rod 404 is fixedly installed on the top wall of the reinforcing rib sleeve 403, and a fixing ring 405 is fixedly installed on the surface of the upper end of the damping rod 404, a shock-absorbing spring 406 is sleeved on the lower end of the damping rod 404, and the top of the shock-absorbing spring 406 is fixedly connected to the bottom of the fixing ring 405, and the bottom of the shock-absorbing spring 406 is fixedly connected to the bottom wall of the reinforcing rib cylinder 401. During the operation of the falling film chiller body 3, large vibrations are generated and the vibrations are accompanied by noise, thus causing noise pollution. By means of four noise reduction components 4 arranged between the base 1 and the support seat 2, when the falling film chiller body 3 drives the support seat 2 to vibrate, the vibration of the support seat 2 will squeeze the rubber ring 402 between the reinforcing rib sleeve 403 and the reinforcing rib cylinder 401 at the bottom of the support seat 2. The rubber ring 402 is an elastic rubber ring and can absorb a certain amount of vibration. At the same time, when the support seat 2 drives the bottom reinforcing rib sleeve 403 to move downward, the fixing ring 405 on the surface of the damping rod 404 squeezes the shock-absorbing spring 406 to compress and reduce the vibration amplitude, thereby reducing the noise generated by the vibration, which is beneficial to energy saving and environmental protection.

[0021] See also Figure 1-2In the embodiment of the utility model, the inner and outer diameters of the reinforcing rib cylinder 401 are equal to the inner and outer diameters of the rubber ring 402. During the vibration of the falling film chiller, the rubber ring 402 will be slightly squeezed and deformed. Since the size of the rubber ring 402 is equal to the cross-sectional size of the reinforcing rib cylinder 401, there is a certain gap between the rubber ring 402 and the inner wall of the reinforcing rib sleeve 403, so that the rubber ring 402 is not affected when it is squeezed and deformed.

[0022] See also Figure 1-2 In the embodiment of the utility model, the rubber ring 402 is an elastic rubber ring, and the thickness of the rubber ring 402 is 3 cm to 3.5 cm. Since the rubber ring 402 is an elastic rubber ring, it can absorb a certain amount of vibration during the working vibration of the falling film chiller, thereby reducing the noise generated by the vibration.

[0023] See also Figure 1 In the embodiment of the utility model: a plurality of honeycomb-shaped sound-absorbing holes are evenly distributed in a row on the surface of the sound insulation board 5, and the inside of the honeycomb-shaped sound-absorbing holes is filled with sound-absorbing cotton. The arrangement of the honeycomb-shaped sound-absorbing holes and the sound-absorbing cotton can absorb the energy of the sound waves, thereby reducing the reflection and propagation of the noise, and effectively reducing the noise. At the same time, part of the heat emitted by the falling film chiller body 3 can be discharged to the outside through the sound-absorbing cotton in the honeycomb-shaped sound-absorbing holes, thereby improving the heat dissipation efficiency.

[0024] See also Figure 1 In the embodiment of the utility model, a heat dissipation fan 7 is fixedly installed in the middle of the support plate 6, and the heat dissipation fan 7 is located directly above the falling film chiller body 3. Through the setting of the heat dissipation fan 7, the heat dissipation fan 7 discharges the heat emitted by the falling film chiller body 3 to the outside of the sound insulation board 5, thereby improving the heat dissipation efficiency.

[0025] Working principle: When the power is turned on, during the operation of the falling film chiller body 3, a large vibration is generated and the vibration is accompanied by noise, thereby causing noise pollution. Through the four noise reduction components 4 arranged between the base 1 and the support base 2, when the falling film chiller body 3 drives the support base 2 to vibrate, the vibration of the support base 2 will squeeze the rubber ring 402 between the reinforcing rib sleeve 403 and the reinforcing rib cylinder 401 at the bottom of the support base 2. The rubber ring 402 is an elastic rubber ring that can absorb a certain amount of vibration. At the same time, the support base 2 drives the bottom reinforcing rib sleeve 403 to vibrate. When the rib sleeve 403 moves downward, the fixing ring 405 on the surface of the damping rod 404 squeezes the shock-absorbing spring 406 to reduce the vibration amplitude, thereby reducing the noise generated by the vibration. At the same time, the honeycomb silencer holes equidistantly arranged on the surface of the sound insulation board 5 and the silencer cotton filled in the honeycomb silencer holes can absorb the energy of the sound waves, thereby reducing the reflection and propagation of the noise, effectively reducing the noise. At the same time, part of the heat emitted by the falling film chiller body 3 can be discharged to the outside through the silencer cotton in the honeycomb silencer holes, thereby improving the heat dissipation efficiency.
