Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to an energy-saving variable frequency chiller. Background Technology

[0002] Variable frequency chillers are high-efficiency refrigeration equipment that dynamically matches the cooling capacity to the load demand by adjusting the compressor speed through variable frequency technology. The working principle of the chiller is vapor compression refrigeration, which means that the liquid refrigerant absorbs heat when it vaporizes and releases heat when it condenses. However, while variable frequency chillers are highly efficient and energy-saving, they also generate noise.

[0003] In the prior art, such as the patent with publication number CN211823417U, a variable frequency chiller is disclosed, including a base. The lower end of the base is fixedly connected to a support device, and the upper end of the base is fixedly connected to a compressor and a chassis. The output end of the compressor is fixedly connected to a water pipe, and the other end of the water pipe is fixedly connected to a connecting flange. The compressor is covered with a soundproof cover, which is connected to the base through a sliding device. A through groove is provided on the side wall of the soundproof cover, and a soundproof plate is provided through the upper end of the soundproof cover. A connecting plate is fixedly connected to the upper end of the soundproof plate, and a sealing device is provided through the soundproof plate.

[0004] The above structure can greatly reduce the noise generated by the compressor. However, during the overall operation of the water chiller, the compressor, fan and other components are installed in the chassis and will generate noise when running at high speed. The sealing effect at the connection of the chassis is not good, resulting in a lot of noise. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an energy-saving variable frequency chiller to solve the problems of poor sealing effect at the connection of the chassis and high noise.

[0006] Based on the above objectives, this utility model provides an energy-saving variable frequency chiller, including a chassis that houses components such as a compressor and a fan. A base is fixedly installed at the bottom of the chassis. Multiple sets of sound-insulating cotton are arrayed inside the chassis, and multiple sets of sound-insulating covers are fixedly installed around the outside of the chassis. A silencer is provided on the inner wall of the top of the chassis.

[0007] A cover is hinged to one side of the opening of the chassis. A pad is provided at the opening of the chassis, and the pad is snapped into the cover. A pressure-applying component is provided between the pad and the cover.

[0008] An electric telescopic rod is movably connected to one side of the chassis, and the output end of the electric telescopic rod is movably connected to one side of the cover.

[0009] Preferably, the pressure-applying component includes a bracket fixedly installed inside the chassis, with rollers rotatably installed at both ends of the bracket, and a swivel seat provided on one side of the bracket. The swivel seat is rotatably installed inside the chassis, and a roller is rotatably connected inside the swivel seat. A cable is connected between the roller and the roller, with one end of the cable connected to the top of the pad and the other end connected to the top of the cover.

[0010] Preferably, the pad comprises a galvanized steel sheet, the interior of which is filled with melamine foam, and both the upper and lower ends of the galvanized steel sheet are provided with slots.

[0011] Preferably, the bottom of the cover and the base are provided with a card strip corresponding to the card slot, and the card strip is provided with a sound insulation strip.

[0012] Preferably, the pad is slidably installed at the opening of the chassis, and the chassis is composed of an aluminum alloy frame.

[0013] Preferably, the interior of the cover is filled with melamine foam.

[0014] The beneficial effects of this utility model are:

[0015] When the chiller is running, it generates noise at high speed. The noise is caused by the opening of the electric telescopic rod. Since one end of the cover is hinged to the chassis, the cover rotates until it aligns with the opening of the chassis. The pressure component reduces the gap between the pad and the cover, improving the sealing effect. In addition, the soundproof cover and sound insulation cotton installed on the outside of the chassis work together to reduce noise. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an energy-saving variable frequency chiller includes a chassis 1 that houses components such as a compressor and a fan. A base 2 is fixedly installed at the bottom of the chassis 1. Multiple sets of sound insulation cotton 5 are arranged in an array inside the chassis 1, and multiple sets of sound insulation covers 19 are fixedly installed around the outside of the chassis 1. A silencer 4 is provided on the inner wall of the top of the chassis 1.

[0024] A cover 3 is hinged to one side of the opening of the chassis 1. A pad 7 is provided at the opening of the chassis 1. The pad 7 is snapped into the cover 3. A pressure-applying component 6 is provided between the pad 7 and the cover 3.

[0025] An electric telescopic rod 12 is movably connected to one side of the chassis 1, and the output end of the electric telescopic rod 12 is movably connected to one side of the cover 3.

[0026] In this embodiment, when the chiller is running, noise is generated at high speed. The electric telescopic rod 12 opens, and since one end of the cover 3 is hinged to the casing 1, the cover 3 is rotated until it coincides with the opening of the casing 1. The pressure component 6 reduces the gap between the pad 7 and the cover 3, improving the sealing effect. In addition, the soundproof cover 19 installed on the outside of the casing 1 and the soundproof cotton 5 work together to reduce noise.

[0027] As one implementation method, such as Figure 3 and Figure 4 As shown, the pressure-applying component 6 includes a bracket 13 fixedly installed inside the chassis 1. Rollers 14 are rotatably installed at both ends of the bracket 13. A swivel seat 16 is provided on one side of the bracket 13. The swivel seat 16 is rotatably installed inside the chassis 1, and a roller 17 is rotatably connected inside the swivel seat 16. A cable 18 is connected between the roller 17 and the roller 14. One end of the cable 18 is connected to the top of the pad 7, and the other end is connected to the top of the cover 3.

[0028] In this embodiment, the cover 3 is opened by the electric telescopic rod 12. Since one end of the cover 3 is hinged to the housing 1, the cover 3 is rotated until it coincides with the opening of the housing 1. When the cover 3 is closed, the pad 7 moves downward under its own weight. The cable 18 at the top of the pad 7 slides on the roller 17 in the rotator 16 and the roller 14 on the bracket 13. At the same time as the cover 3 is closed, the pad 7 moves downward to the bottom until the pad 7 and the cover 3 are engaged with each other, reducing the gap between them.

[0029] As one implementation method, such as Figure 4 As shown, the pad 7 includes a galvanized steel plate 8, the interior of which is filled with melamine foam 9, and both the upper and lower ends of the galvanized steel plate 8 are provided with slots 10.

[0030] The bottom of the cover 3 and the base 2 are both provided with a card strip 11 corresponding to the card slot 10, and a sound insulation strip is provided on the card strip 11.

[0031] In this embodiment, as the cover 3 is closed, the pad 7 moves downward to the bottom until the slot 10 on the galvanized steel plate 8 engages with the bottom of the cover 3 and the base 2, reducing gaps, improving sealing effect, and enhancing the tightness of the connection between the casing 1 and the cover 3.

[0032] As one implementation method, such as Figure 1 , Figure 2 As shown, the pad 7 is slidably installed at the opening of the chassis 1, which is composed of an aluminum alloy frame.

[0033] The interior of the cover 3 is filled with melamine foam 9.

[0034] In this embodiment, the melamine foam 9 installed inside the cover 3 and the silencer 4 inside the chassis 1 enhance the noise reduction effect to the greatest extent. In addition, the soundproof cover 19 installed outside the chassis 1 and the soundproof cotton 5 work together to reduce noise.

[0035] Working principle: When in use, the compressor, fan and other components are installed in the casing 1. When the chiller is running, it generates noise at high speed. The electric telescopic rod 12 opens the casing. Since one end of the cover 3 is hinged to the casing 1, the cover 3 is rotated until it coincides with the opening of the casing 1. When the cover 3 is closed, the pad 7 moves downward due to its own weight. The cable 18 at the top of the pad 7 slides on the roller 17 in the swivel seat 16 and the roller 14 on the bracket 13. As the cover 3 closes, the pad 7 moves downward to the bottom until the slot 10 on the pad 7 engages with the bottom of the cover 3 and the base 2, reducing gaps, improving the sealing effect, and improving the tightness of the connection between the casing 1 and the cover 3.

[0036] Meanwhile, the melamine foam 9 inside the cover 3 and the silencer 4 inside the chassis 1 enhance the noise reduction effect to the greatest extent. In addition, the soundproof cover 19 installed on the outside of the chassis 1 and the soundproof cotton 5 work together to reduce noise.
