Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a top-mounted refrigeration unit. Background Technology
[0002] Refrigeration equipment is a device used to lower the temperature and maintain a low-temperature environment. It is widely used in many fields such as industry, commerce, medical care, and home. Among them, commercial freezers or ice makers are commonly used. In order to ensure heat dissipation, the refrigeration unit that is used with the refrigeration equipment is usually installed on the top.
[0003] A refrigeration unit is the core component of a refrigeration system. It transfers heat from one place to another through a series of thermodynamic processes to achieve a cooling effect. It typically consists of a compressor, condenser, throttling device, and evaporator. The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator and compresses it, increasing its pressure and temperature to become high-temperature, high-pressure refrigerant gas. This high-temperature, high-pressure refrigerant gas enters the condenser, where it exchanges heat with the cooling medium (air or water), transferring heat to the medium and condensing itself into high-temperature, high-pressure liquid refrigerant. This high-temperature, high-pressure liquid refrigerant is then throttled and depressurized by the throttling device, becoming low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant enters the evaporator, where it absorbs heat and evaporates, becoming low-temperature, low-pressure refrigerant gas, thus absorbing heat from the surrounding environment to achieve a cooling effect. The evaporated refrigerant gas is then drawn back into the compressor, starting a new cycle.
[0004] While existing refrigeration units offer numerous advantages during use, they still present the following problems: it is inconvenient to clean the filter screen of the cooling fan that is paired with the condenser. Since both the refrigeration unit and the filter screen are located at the top of the refrigeration equipment, and the filter screen is used to filter impurities in the air, it is inconvenient for staff to clean the filter screen, thus affecting the maintenance efficiency of the filter screen. Utility Model Content
[0005] To address the problems in the existing technology, this utility model provides a top-mounted refrigeration unit.
[0006] The technical solution adopted by this utility model to solve its technical problem is a top-mounted refrigeration unit, including a refrigeration cabinet, a retaining sleeve, and a connecting ring. The refrigeration unit body is installed on one side of the upper outer wall of the refrigeration cabinet. A heat dissipation pipe is inserted and installed on one side of the upper outer wall of the refrigeration unit body. A connecting ring is provided on the upper outer wall of the heat dissipation pipe. Retaining sleeves are installed on both outer walls of the refrigeration cabinet. A rotating shaft is rotatably installed inside the retaining sleeve. A connecting frame is installed on the outer wall of one end of the rotating shaft. A handle is installed through the outer wall of one end of the retaining sleeve.
[0007] By adopting the above technical solution, the refrigeration unit can cool the inside of the refrigeration cabinet. The refrigeration unit is placed at the top of the refrigeration cabinet, which is conducive to heat dissipation and ensures the heat dissipation efficiency of the refrigeration unit. The heat dissipation pipe is used to dissipate the heat of the refrigeration unit, and the connecting ring extends the heat dissipation pipe, which helps to ensure the heat dissipation trajectory. In addition, by turning the handle and driving the connecting frame and connecting ring to rotate, the filter screen can be lowered, making it easier for the staff to clean the filter screen. This avoids the filter screen being too high, which is not conducive to cleaning, and can improve the cleaning efficiency of the staff.
[0008] Specifically, a rectangular array of bases is installed on the lower outer wall of the refrigeration cabinet, and cabinet doors are rotatably connected to the outer walls on both sides of the refrigeration cabinet.
[0009] By adopting the above technical solution, the base provides stable support for the refrigeration cabinet, maintaining its stability when placed. The cabinet door can cover the interior of the refrigeration cabinet, ensuring its relative airtightness and facilitating users to take items out of the cabinet.
[0010] Specifically, a sealing ring is adhered and fixed to the lower outer wall of the connecting ring, and the lower outer wall of the sealing ring is in contact with the upper outer wall of the heat dissipation pipe.
[0011] By adopting the above technical solution, the sealing ring can ensure the sealing between the connecting ring and the heat dissipation pipe, ensuring that the heat dissipation trajectory is controlled, and together with the filter screen, it can effectively prevent dust, debris, moisture, etc. from entering the heat dissipation pipe. This can protect the cooling fan and other components inside the heat dissipation pipe from the corrosion of external pollutants, reduce the probability of equipment failure, and extend the service life of the heat dissipation pipe and related components.
[0012] Specifically, a cover plate is screwed to the outer wall of the upper end of the connecting ring, and a filter screen is provided inside the cover plate.
[0013] By adopting the above technical solution, the filter screen can block the connecting ring, prevent foreign objects from directly entering the heat dissipation pipe, ensure the cleanliness of the air entering the heat dissipation pipe, thereby ensuring the working efficiency of the cooling fan, ensuring the normal operation of the refrigeration unit, and the filter screen can be directly disassembled and cleaned by removing the cover plate.
[0014] Specifically, a fixing block is installed on one side of the outer wall of the handle, and a bolt is threaded inside the fixing block, with one end of the bolt contacting the outer wall of the refrigeration cabinet.
[0015] By adopting the above technical solution, the horizontal movement caused by the bolt rotating inside the fixing block can cause the bolt to squeeze the refrigeration cabinet, thereby achieving the purpose of fixing the handle's position. Furthermore, by rotating the handle, the operator can drive the rotating shaft, connecting frame, and connecting ring to rotate, thereby adjusting the position of the filter screen and enhancing the stability and adjustability of the equipment.
[0016] Specifically, fasteners are installed on both outer walls of the connecting frame. The connecting frame adopts an L-shaped design and is connected to the connecting ring by screws through the fasteners.
[0017] By adopting the above technical solutions, the fasteners ensure the stability of the connection between the connecting frame and the connecting ring, ensuring that the connecting ring can move with the rotation of the connecting frame. Furthermore, the use of screw connections and fasteners facilitates the installation and disassembly of the connecting frame, making it easier for the equipment to be assembled, maintained, and repaired.
[0018] Specifically, the size of the connecting ring is adapted to the size of the heat dissipation pipe, and a cooling fan is installed on one side of the inner wall of the heat dissipation pipe.
[0019] By adopting the above technical solution, the size adaptation ensures that the connecting ring can be tightly installed on the heat dissipation pipe through the sealing ring, guaranteeing the sealing and stability of the connection. This helps prevent heat leakage and the ingress of external contaminants, and the cooling fan can accelerate airflow and improve heat dissipation efficiency. Through forced convection, the heat generated by the refrigeration unit is quickly discharged from the heat dissipation pipe, allowing the refrigeration unit to operate at a suitable temperature, ensuring its cooling effect and reliability.
[0020] The beneficial effects of this utility model are:
[0021] (1) The refrigeration unit top-mounted refrigeration equipment of this utility model can lower the position of the filter screen, making it easier for staff to clean the filter screen, avoiding the filter screen being too high and difficult to clean, and improving the cleaning efficiency of the staff.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides a top-mounted refrigeration unit, comprising a refrigeration cabinet 1, a retaining sleeve 2, and a connecting ring 3. A refrigeration unit body 11 is installed on one side of the upper outer wall of the refrigeration cabinet 1. A heat dissipation pipe 12 is inserted and installed on one side of the upper outer wall of the refrigeration unit body 11. A connecting ring 3 is provided on the upper outer wall of the heat dissipation pipe 12. Retaining sleeves 2 are installed on both outer walls of the refrigeration cabinet 1. A rotating shaft 21 is rotatably installed inside the retaining sleeve 2. A connecting bracket 22 is installed on the outer wall of one end of the rotating shaft 21. A handle 24 is installed through the outer wall of one end of the rotating shaft 21.
[0030] During use, the refrigeration unit body 11 can cool the inside of the refrigeration cabinet 1. The refrigeration unit body 11 is placed on the upper part of the refrigeration cabinet 1, which is conducive to heat dissipation and ensures the heat dissipation efficiency of the refrigeration unit body 11. The heat dissipation pipe 12 is used to dissipate the heat of the refrigeration unit body 11, and the connecting ring 3 extends the heat dissipation pipe 12, which helps to ensure the heat dissipation trajectory. By turning the handle 24, the operator can drive the connecting bracket 22 and the connecting ring 3 to rotate, which can lower the position of the filter screen 33, making it easier for the operator to clean the filter screen 33. This avoids the filter screen 33 being too high, which is not conducive to cleaning, and can improve the cleaning efficiency of the operator.
[0031] To maintain a stable position, for example, such as Figure 1 As shown, a rectangular array of bases is installed on the lower outer wall of the refrigeration cabinet 1, and cabinet doors 13 are rotatably connected to the outer walls on both sides of the refrigeration cabinet 1.
[0032] When in use, the base provides stable support for the refrigeration cabinet 1, maintaining the stability of the refrigeration cabinet 1 when placed. The cabinet door 13 can cover the inside of the refrigeration cabinet 1, ensuring the relative airtightness of the inside of the refrigeration cabinet 1, and making it convenient for users to take out and put in items inside the refrigeration cabinet 1.
[0033] For sealing purposes, exemplarily, such as Figure 4 As shown, a sealing ring 31 is adhered and fixed to the lower outer wall of the connecting ring 3, and the lower outer wall of the sealing ring 31 is in contact with the upper outer wall of the heat dissipation pipe 12.
[0034] During use, the sealing ring 31 ensures a tight seal between the connecting ring 3 and the heat dissipation pipe 12, ensuring controlled heat dissipation trajectory. Combined with the filter screen 33, it effectively prevents dust, debris, and moisture from entering the heat dissipation pipe 12. This protects components such as the cooling fan 14 inside the heat dissipation pipe 12 from external contaminants, reduces the probability of equipment failure, and extends the service life of the heat dissipation pipe 12 and related components.
[0035] To mask the filtering, for example, such as Figure 4 As shown, a cover plate 32 is screwed to the outer wall of the upper end of the connecting ring 3, and a filter screen 33 is provided inside the cover plate 32.
[0036] When in use, the filter screen 33 can block the connecting ring 3, preventing foreign objects from directly entering the heat dissipation pipe 12, ensuring the cleanliness of the air entering the heat dissipation pipe 12, thereby ensuring the working efficiency of the cooling fan 14, ensuring the normal operation of the refrigeration unit body 11, and the filter screen 33 can be directly disassembled and cleaned by removing the cover plate 32.
[0037] For fixed connections, for example, such as Figure 4 As shown, a fixing block 25 is installed on one side of the outer wall of the handle 24. A bolt 26 is threaded inside the fixing block 25, and one end of the bolt 26 is in contact with the outer wall of the refrigeration cabinet 1.
[0038] During use, the horizontal movement caused by the rotation of bolt 26 inside the fixing block 25 can cause bolt 26 to press against the refrigeration cabinet 1, thereby fixing the position of handle 24. Furthermore, by rotating handle 24, the operator can drive the rotating shaft 21, connecting frame 22 and connecting ring 3 to rotate, thereby adjusting the position of filter screen 33 and enhancing the stability and adjustability of the equipment.
[0039] For example, to enable coordinated movement, such as... Figure 2 As shown, fasteners 23 are installed on both outer walls of the connecting frame 22. The connecting frame 22 adopts an L-shaped design, and the connecting frame 22 is connected to the connecting ring 3 by screws through the fasteners 23.
[0040] During use, fastener 23 ensures the stability of the connection between the connecting frame 22 and the connecting ring 3, and ensures that the connecting ring 3 can move with the rotation of the connecting frame 22. The use of screw connection and fastener 23 facilitates the installation and disassembly of the connecting frame 22, and facilitates the assembly, maintenance and repair of the equipment.
[0041] For heat dissipation, for example, such as Figure 2 As shown, the size of the connecting ring 3 is adapted to the size of the heat pipe 12, and a cooling fan 14 is installed on one side of the inner wall of the heat pipe 12.
[0042] During use, the size fit ensures that the connecting ring 3 can be tightly installed on the heat dissipation pipe 12 through the sealing ring 31, guaranteeing the sealing and stability of the connection. This helps prevent heat leakage and the ingress of external contaminants, and the cooling fan 14 can accelerate airflow and improve heat dissipation efficiency. Through forced convection, the heat generated by the refrigeration unit body 11 is quickly discharged from the heat dissipation pipe 12, enabling the refrigeration unit body 11 to operate at a suitable temperature, ensuring its cooling effect and reliability.
[0043] When this utility model is in use, the refrigeration unit body 11 is turned on, and it begins to cool down the inside of the refrigeration cabinet 1. During the cooling process, the cooling fan 14 is turned on to accelerate the air flow and quickly discharge the heat from the heat dissipation pipe 12 through forced convection, so that the refrigeration unit body 11 can operate at a suitable temperature.
[0044] When the filter screen 33 needs to be cleaned, the staff rotates the handle 24, which drives the shaft 21 connected to it to rotate. The rotation of the shaft 21 drives the connecting bracket 22 to rotate, and the connecting ring 3 will move with the rotation of the connecting bracket 22, causing the filter screen 33 to move down. The staff can then remove the screws on the cover plate 32 at the top of the connecting ring 3 to directly disassemble and clean the filter screen 33.
[0045] After the filter screen 33 is cleaned, the staff rotates the connecting ring 3 to reset it by rotating the handle 24. The sealing ring 31 ensures the sealing between the connecting ring 3 and the heat dissipation pipe 12. The staff rotates the bolt 26 connected to the thread inside the fixing block 25, so that the bolt 26 moves horizontally within the fixing block 25 until one end of the bolt 26 presses against the outer wall of the refrigeration cabinet 1, thereby achieving the purpose of fixing the use position of the handle 24.
[0046] It should be noted that this utility model is a top-mounted refrigeration unit. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
