Description

Technical Field

[0001] This utility model relates to the field of chiller technology, specifically a chiller for use in cold regions. Background Technology

[0002] Chillers, also known as freezers, refrigeration units, or cooling units, are widely used across various industries. The process of an air-cooled water chiller unit involves heat exchange between water and refrigerant via an evaporator. The refrigerant system absorbs the heat load from the water, cooling it to produce chilled water. The refrigerant then carries the heat to the condenser via a compressor, and finally, the heat is dissipated into the outside air by a cooling fan – this is known as air cooling.

[0003] When a chiller is working, its air inlet generates significant noise due to airflow. Prolonged exposure to this environment can negatively impact health and product quality. In cold regions, the air inlet of some traditional chillers is easily clogged by snow and ice crystals. Furthermore, the filters in some traditional fixed air inlets are difficult to disassemble, resulting in low maintenance efficiency and a lack of self-cleaning mechanisms, leading to decreased heat dissipation efficiency and increased energy consumption.

[0004] Based on this, this solution proposes a chiller for cold regions. Utility Model Content

[0008] Using the above technical solution, in cold environments, the heating wire heats the air, and the fan blows the heated air through the air outlet and nozzles to the air inlet, preventing snow and ice crystals from clogging the air inlet and ensuring the normal operation of the chiller in cold regions.

[0009] Preferably, a pull handle is fixedly installed on the outer side of the inspection plate.

[0010] Using the above technical solution, the inspection panel can be easily opened by pulling the handle.

[0011] Preferably, a return spring is fixedly connected between the sliding sleeve and the sliding rod.

[0012] By adopting the above technical solution, the return spring facilitates the reset of the sliding sleeve.

[0013] Preferably, a sealing ring is fixedly fitted onto each sound-absorbing panel.

[0014] By adopting the above technical solution, the sealing ring ensures the airtightness between the sound-absorbing panel and the air inlet pipe, preventing noise leakage.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-6This utility model provides a technical solution: a chiller for cold regions, comprising a chiller body 1, an air inlet pipe 2 fixedly installed on one side of the chiller body 1, a fixing plate 5 snapped onto the front end of the air inlet pipe 2, and a maintenance plate 9 snapped onto one side of the air inlet pipe 2, a pull handle 8 fixedly installed on the outer side of the maintenance plate 9, an air inlet hole opened on the fixing plate 5, a filter screen 6 snapped into the air inlet hole, an operation box 3 fixedly installed on the top of the air inlet pipe 2, and a micro motor 10 fixedly installed on the top of the operation box 3. A mounting hole is provided at the front end of the 3, and a slide rod 17 is fixedly installed in the mounting hole. A slide sleeve 16 is slidably sleeved on the slide rod 17. A linkage rack 18 and a reciprocating rack 20 are fixedly installed at both ends of the slide sleeve 16, respectively. A return spring 19 is fixedly sleeved between the slide sleeve 16 and the slide rod 17. A linkage gear 11 is rotatably installed at the front end of the air inlet pipe 2. The linkage gear 11 meshes with the linkage rack 18, and a brush 4 is fixedly installed on the linkage rack 18. A half gear 21 located inside the operation box 3 is fixedly sleeved on the output shaft of the micro motor 10.

[0036] In this embodiment, when the chiller is started, the micro motor 10 is powered on and runs, and the half gear 21 on its output shaft begins to rotate. The half gear 21 intermittently meshes with the reciprocating rack 20, driving the sliding sleeve 16 to slide horizontally back and forth along the sliding rod 17. The reciprocating motion of the sliding sleeve 16 is transmitted to the linkage gear 11 through the linkage rack 18, driving the linkage gear 11 to rotate, thereby driving the brush 4 to move left and right on the surface of the filter screen 6 to remove accumulated dust and impurities.

[0037] The return spring 19 is compressed or stretched when the sliding sleeve 16 slides. When the half gear 21 disengages from the reciprocating rack 20, the return spring 19 pushes the sliding sleeve 16 back to the initial position, preparing for the next cleaning cycle.

[0038] Combination Figure 1-6 As shown in this embodiment, multiple sound-absorbing panels 23 are installed inside the air inlet pipe 2. Each sound-absorbing panel 23 has multiple sound-absorbing holes and a sealing ring 22 is fixedly fitted onto it. The main material of the sound-absorbing panel 23 is polyester fiber.

[0039] In this embodiment, the sound-absorbing panel 23 is installed inside the air inlet duct 2 by a snap-fit ​​method. The multiple sound-absorbing holes evenly opened on its surface can effectively disperse and absorb the sound wave energy generated by the airflow. The sound-absorbing panel 23 is made of polyester fiber material, which further enhances the sound absorption performance. The sealing ring 22 is tightly fitted on the edge of the sound-absorbing panel 23 to ensure the sealing between the sound-absorbing panel 23 and the inner wall of the air inlet duct 2, preventing noise leakage and air leakage. When it is necessary to clean or replace the sound-absorbing panel 23, the operator can remove the inspection plate 9 and take out the sound-absorbing panel 23 directly from the air inlet duct 2. The operation is simple and does not require complicated tools.

[0040] Combination Figure 1-6 As shown, in this embodiment, a heating box 7 is fixedly installed on one side of the air inlet pipe 2, and an air outlet pipe 15 and a fan 13 are fixedly installed on both sides of the heating box 7 respectively. A heating wire 14 is fixedly installed inside the heating box 7, and a nozzle 12 is fixedly installed at one end of the air outlet pipe 15.

[0041] In this embodiment, when the heating wire 14 is energized to generate heat in a cold environment, the fan 13 starts and delivers the hot air in the heating box 7 to the nozzle 12 through the air outlet 15. The nozzle 12 blows the heated air evenly toward the air inlet area of ​​the air inlet pipe 2 to prevent the air inlet from being blocked by snow or ice crystals in a low-temperature environment.

[0042] The linkage design between the heating box 7 and the fan 13 ensures a continuous supply of preheated air, guaranteeing the stable operation of the chiller body 1 under low temperature conditions. Operators can flexibly control the preheating temperature to adapt to different environmental requirements by adjusting the power of the heating wire 14 and the speed of the fan 13.

[0043] Working principle of this utility model: The working principle of this utility model for a chiller used in cold regions mainly involves three aspects: self-cleaning of the air intake system, noise reduction, and air intake preheating in cold environments, as detailed below:

[0044] 1. Self-cleaning mechanism of the air intake system

[0045] Components include: air inlet duct 2, fixing plate 5, filter screen 6, operation box 3, micro motor 10, linkage gear 11, brush 4, etc.

[0046] Working principle: When the chiller body 1 is working, air enters the chiller body 1 through the air inlet pipe 2 for heat exchange. To prevent the filter screen 6 from clogging, the micro motor 10 starts, and the half gear 21 on its output shaft rotates. The half gear 21 intermittently meshes with the reciprocating rack 20, driving the sliding sleeve 16 to slide back and forth on the slide rod 17. The reciprocating motion of the sliding sleeve 16 drives the linkage gear 11 to rotate through the linkage rack 18, thereby driving the brush 4 to move on the surface of the filter screen 6 to achieve the self-cleaning function. The return spring 19 ensures that the sliding sleeve 16 can return to its original position when the half gear 21 is not meshing, preparing for the next cleaning.

[0047] 2. Noise reduction mechanism

[0048] Components include: air inlet duct 2, sound absorption panel 23, sealing ring 22, etc.

[0049] Working principle: Multiple sound-absorbing panels 23 are installed inside the air inlet pipe 2. The sound-absorbing panels 23 have multiple sound-absorbing holes, which effectively absorb the noise generated by air flow. The sealing ring 22 ensures the sealing between the sound-absorbing panels 23 and the air inlet pipe 2 to prevent noise leakage. The main material of the sound-absorbing panels 23 is polyester fiber, which has good sound absorption performance and further reduces the noise level.

[0050] 3. Air intake preheating mechanism in cold environments

[0051] Components include: heating box 7, heating wire 14, fan 13, air outlet pipe 15, nozzle 12, etc.

[0052] Working principle: In cold regions, the air inlet is easily blocked by snow and ice crystals. To prevent this, the heating wire 14 heats the air in the heating box 7, and the fan 13 starts to blow the heated air through the air outlet duct 15 and the nozzle 12 toward the air inlet, preventing snow and ice crystals from blocking it. This mechanism ensures that the chiller can still operate normally in cold environments, improving the stability and reliability of the equipment.

[0053] In summary, this utility model of a chiller for cold regions effectively solves the problems encountered by traditional chillers when used in cold regions through a self-cleaning mechanism, a noise reduction mechanism, and an air intake preheating mechanism, thereby improving the performance and service life of the equipment.
