Description

Technical Field

[0001] The utility model relates to the technical field of chillers, in particular to a noise-reducing constant-temperature chiller. Background Art

[0002] Constant temperature chillers are widely used in cooling equipment. When in use, they need to be connected to the working equipment that needs to be cooled and connected to circulating water.

[0003] When the constant temperature chiller is working, it cools down the circulating water. The cooled circulating water enters the working equipment for circulation and takes the heat out of the working equipment. The heated circulating water enters the constant temperature chiller again and the constant temperature chiller cools down the circulating water again. The above cycle is repeated to achieve cyclic cooling of the working equipment.

[0004] The constant temperature chiller in the existing technology is a cooling device with a constant temperature control function. It consists of a compressor, condenser, evaporator, water pump, circulation pipeline and thermostat. When the constant temperature chiller is working, the compressor, condenser, evaporator, water pump and other components inside it will generate a lot of noise, which has a certain impact on the hearing of surrounding staff. Therefore, it is necessary to improve the design of related technologies. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a noise reduction constant temperature chiller.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a noise-reducing constant-temperature chiller, comprising a frame, in which a condenser, an evaporator, a compressor and a water tank coil are arranged, end sound insulation panels are fixed at both ends of the frame, side sound insulation panels are hinged on both sides of the frame, and a fixing assembly for fixing the side sound insulation panels is provided on the frame.

[0007] By adopting the above technical solution, the end sound insulation panels and the side sound insulation panels are both made of panels with sound insulation properties. The frame, the end sound insulation panels and the side sound insulation panels together form a closed structure, which covers the condenser, the evaporator, the compressor and the water tank coil. During the operation of the constant temperature chiller, it plays a good sound insulation role, which is beneficial to protecting the hearing system of the staff around the chiller.

[0008] Furthermore, both sides of the frame are provided with mounting grooves that cooperate with the lateral sound insulation plates, and an annular rubber ring is attached to and fixed on the inner wall of the mounting groove.

[0009] By adopting the above technical solution, the annular rubber ring is made of rubber material with good elastic properties. After the side sound insulation board is closed, the probability of noise being transmitted from between the side sound insulation board and the mounting groove of the rack is reduced.

[0010] Furthermore, the fixing assembly is located on a side of the lateral sound insulation plate away from the hinge between the lateral sound insulation plate and the frame, and the fixing assembly includes a threaded rod threadedly connected to the side wall of the frame, a connecting block fixed to an end of the threaded rod away from the frame, and a hexagonal block fixed to an end of the connecting block away from the threaded rod, and the side wall of one side of the connecting block abuts against the side of the lateral sound insulation plate away from the frame.

[0011] By adopting the above technical solution, when installing or repairing the condenser, evaporator, compressor or water tank coil, the staff only needs to turn the hexagonal block with a wrench to rotate the threaded rod, so that the connecting block is separated from the lateral sound insulation board, so that the staff can open the lateral sound insulation board and carry out installation or maintenance work.

[0012] Furthermore, an L-shaped sound insulation board is fixed on the side of the lateral sound insulation board close to the condenser, and two L-shaped sound insulation boards are provided on the same side of the frame.

[0013] By adopting the above technical solution, the setting of the L-shaped sound insulation board adds a sound insulation barrier, which works together with the lateral sound insulation board to improve the sound insulation effect.

[0014] Furthermore, a sound insulation felt is fixed to a side of the end sound insulation board close to the condenser.

[0015] By adopting the above technical solution, the sound insulation felt is a high-density coiled material with a certain flexibility made of rubber, polymer materials, etc. as the main raw materials. The provision of the sound insulation felt enhances the sound insulation effect of the end sound insulation board.

[0016] Furthermore, a plurality of ventilation holes are provided on the horizontal plate at the bottom of the rack, a plurality of mounting tubes are fixed on the top of the rack, and a heat dissipation fan for blowing air into the inside of the rack is provided in each mounting tube.

[0017] By adopting the above technical solution, after the cooling fan starts working, the heat generated by the condenser, evaporator, compressor or water tank coil is blown out from the air vents, which plays a good heat dissipation role and ensures the normal operation of the constant temperature chiller.

[0018] Furthermore, a mounting plate is fixed to the frame of the rack near the L-shaped sound insulation board, a rubber sheet is fixed to the side of the mounting plate near the L-shaped sound insulation board, and the side of the rubber sheet away from the mounting plate abuts against the side wall of one side of the L-shaped sound insulation board.

[0019] By adopting the above technical solution, the rubber sheet on the mounting plate cooperates with the L-shaped sound insulation board to further enhance the shielding effect of the sound generated by the condenser, evaporator, compressor or water tank coil, and reduce the noise generated during the operation of the constant temperature chiller.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. In this application, the end sound insulation panels and the side sound insulation panels are made of plates with sound insulation properties. The frame, the end sound insulation panels and the side sound insulation panels together form a closed structure, which covers the condenser, evaporator, compressor and water tank coil. During the operation of the constant temperature chiller, it plays a good sound insulation role, which is beneficial to protecting the hearing system of the staff around the chiller;

[0022] 2. In this application, when installing or repairing the condenser, evaporator, compressor or water tank coil, the worker only needs to turn the hexagonal block with a wrench to rotate the threaded rod, so that the connecting block is separated from the side sound insulation board, so that the worker can open the side sound insulation board and carry out installation or repair work;

[0023] 3. In this application, the setting of the L-shaped sound insulation board adds a sound insulation barrier, which works together with the lateral sound insulation board to improve the sound insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-4 As shown, the embodiment of the present application discloses a noise-reducing constant-temperature chiller, including a frame 1, in which a condenser 11, an evaporator 12, a compressor 13 and a water tank coil 14 are arranged (the condenser 11, the evaporator 12, the compressor 13 and the water tank coil 14 all belong to the mature technology of the alignment of the constant-temperature chiller, and the model, structural composition and the pipe connection relationship between the various components do not need to be described in detail here), end sound insulation panels 2 are fixed at both ends of the frame 1 (one of the end sound insulation panels 2 is fixed with a control panel 21 for controlling the operation of the condenser 11, the evaporator 12, the compressor 13 or the water tank coil 14), side sound insulation panels 3 are hinged on both sides of the frame 1, and a fixing assembly 4 for fixing the side sound insulation panels 3 is provided on the frame 1.

[0031] The end sound insulation board 2 and the side sound insulation board 3 are both made of plates with sound insulation properties. The frame 1, the end sound insulation board 2 and the side sound insulation board 3 together form a closed structure, which covers the condenser 11, the evaporator 12, the compressor 13 and the water tank coil 14. During the operation of the constant temperature chiller, it plays a good sound insulation role, which is beneficial to protecting the hearing system of the staff around the chiller.

[0032] Both sides of the frame 1 are provided with mounting slots 15 for the lateral sound insulation panels 3. An annular rubber ring 151 is attached to and secured to the inner wall of the mounting slots 15. Made of a rubber material with excellent elasticity, the annular rubber ring 151 reduces the possibility of noise being transmitted between the lateral sound insulation panels 3 and the mounting slots 15 of the frame 1 when the lateral sound insulation panels 3 are closed.

[0033] The fixing assembly 4 is located on the side of the lateral sound baffle 3, away from the hinge between the lateral sound baffle 3 and the frame 1. It comprises a threaded rod 41 threadedly connected to the side wall of the frame 1, a connecting block 42 fixed to the end of the threaded rod 41 away from the frame 1, and a hexagonal block 43 fixed to the end of the connecting block 42 away from the threaded rod 41. The side wall of the connecting block 42 abuts the side of the lateral sound baffle 3 away from the frame 1. When installing or repairing the condenser 11, evaporator 12, compressor 13, or water tank coil 14, a worker simply turns the hexagonal block 43 with a wrench to rotate the threaded rod 41, disengaging the connecting block 42 from the lateral sound baffle 3, allowing the worker to open the lateral sound baffle 3 and perform installation or repair work.

[0034] An L-shaped sound insulation board 5 is fixed to the side of the lateral sound insulation board 3 near the condenser 11. Two L-shaped sound insulation boards 5 are provided on the same side of the frame 1. The provision of the L-shaped sound insulation board 5 adds a sound barrier, and works in conjunction with the lateral sound insulation board 3 to improve the sound insulation effect.

[0035] A sound insulation felt 22 is fixed to the side of the end sound insulation board 2 close to the condenser 11. The sound insulation felt 22 is a high-density coiled material with a certain degree of flexibility made of rubber, polymer materials, etc. The provision of the sound insulation felt 22 enhances the sound insulation effect of the end sound insulation board 2.

[0036] The horizontal plate at the bottom of the rack 1 is provided with multiple ventilation holes 6. A plurality of mounting tubes 7 are fixed to the top of the rack 1. Each mounting tube 7 houses a cooling fan 71 for blowing air into the interior of the rack 1. When the cooling fan 71 is in operation, it blows heat generated by the condenser 11, evaporator 12, compressor 13, or water tank coil 14 out of the ventilation holes 6, effectively dissipating heat and ensuring the normal operation of the constant temperature chiller.

[0037] A mounting plate 8 is fixed to the frame 1 near the L-shaped sound insulation board 5. A rubber sheet 81 is fixed to the side of the mounting plate 8 near the L-shaped sound insulation board 5. The side of the rubber sheet 81 facing away from the mounting plate 8 abuts against the sidewall of the L-shaped sound insulation board 5. The rubber sheet 81 on the mounting plate 8 cooperates with the L-shaped sound insulation board 5 to further enhance the shielding effect of the sound generated by the condenser 11, evaporator 12, compressor 13, or water tank coil 14, thereby reducing the noise generated during the operation of the constant temperature water chiller.

[0038] The operating principle of a noise-reducing constant-temperature chiller in this embodiment is as follows: the end sound insulation panels 2 and the side sound insulation panels 3 are both made of panels with sound insulation properties. The frame 1, the end sound insulation panels 2 and the side sound insulation panels 3 together form a closed structure, which covers the condenser 11, the evaporator 12, the compressor 13 and the water tank coil 14. During the operation of the constant-temperature chiller, it plays a good sound insulation role, which is beneficial to protecting the hearing system of the staff around the chiller.
