Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a refrigeration unit and its refrigeration cabinet. Background Technology

[0002] In the current commercial refrigeration equipment field, the refrigeration system layout of display refrigerators has long suffered from the technical bottleneck of low space utilization. Traditional refrigeration units typically employ a design scheme where the three core components—compressor, condenser, and evaporator—are installed separately. These components need to be fixed in different positions within the refrigerator cabinet, which not only leads to complex installation procedures and difficult maintenance but also poses a severe challenge to the spatial configuration of the entire refrigeration system. The structural layout of the evaporator is particularly critical, as its coil design and installation location often require a significant amount of operating space, directly encroaching on the effective volume of the refrigerator that could be used for product display.

[0003] Therefore, it is necessary to break through the limitations of existing technologies through system integration innovation. Utility Model Content

[0004] This invention proposes a refrigeration unit and its refrigeration cabinet. By using a fixed assembly with a built-in refrigeration duct as the overall frame, the compressor condenser assembly and heat exchange air supply assembly are integrated within the fixed assembly. Compared to traditional split-type installations, this integrated design significantly simplifies the installation process of the refrigeration unit and reduces installation complexity.

[0005] A refrigeration unit designed for this purpose includes a fixed assembly with built-in refrigeration air ducts, and a compressor condensing assembly and a heat exchange air supply assembly placed within the fixed assembly; The compressor condenser assembly is located outside the refrigeration duct, and the heat exchange air supply assembly is located inside the refrigeration duct, so that the compressor condenser assembly and the heat exchange air supply assembly are integrated into a fixed component and form an integral refrigeration unit.

[0006] The fixed assembly has an installation cavity, which is independently spaced from the refrigeration air duct within the fixed assembly, and the compressor condenser assembly is fixed within the installation cavity.

[0007] The mounting cavity and the cooling air duct are arranged vertically at intervals.

[0008] The mounting cavity is provided with a heat dissipation window and a ventilation port. The compressor condenser assembly is located between the heat dissipation window and the ventilation port. Both the heat dissipation window and the ventilation port are connected to the outside air of the mounting cavity, forming a heat dissipation channel for the compressor condenser assembly.

[0009] The heat dissipation window is equipped with a cooling fan for assisting the cooling of the compressor condenser assembly. External air enters the mounting cavity through the cooling fan and is discharged from the mounting cavity through the vent.

[0010] The fixing component includes a first frame cover, a refrigeration air duct and a heat exchange air supply assembly disposed inside the first frame cover, a compressor condenser assembly located on the top outer side of the first frame cover, and a second frame cover for covering the compressor condenser assembly on the first frame cover; an installation cavity for installing the compressor condenser assembly is formed between the second frame cover and the first frame cover.

[0011] The second frame cover has a vent and a mounting bracket on its side. The mounting bracket has a heat dissipation window for installing a cooling fan. The second frame cover has an installation opening for installing the mounting bracket. Alternatively, the second frame cover and the mounting bracket are integrally formed.

[0012] The first frame cover includes a bracket for mounting a heat exchange and air supply assembly, which includes a fan and an evaporator. One end of the bracket is provided with an inclined end for mounting the fan, and the bracket is provided with a water receiving tray for receiving condensate from the evaporator. The water receiving tray is provided with a drain outlet.

[0013] The first frame cover includes a frame cover fixedly connected to the bracket, the bracket covers the bracket and encloses the evaporator, and a cooling air duct is formed between the frame cover and the bracket; a gap is left between the other end of the bracket and the frame cover to form an air outlet. The first frame cover also includes an outer frame cover fixedly connected to the frame cover, the outer frame cover covering the frame cover, and the compressor condenser assembly includes a compressor and a condenser fixedly on the top of the outer frame cover, and the second frame cover is fixedly connected to the outer frame cover.

[0014] A refrigeration cabinet includes a cabinet body, on which the aforementioned refrigeration unit is mounted; The refrigeration unit is installed on the top of the cabinet, and the air inlet and outlet of the refrigeration air duct are both connected to the inside of the cabinet. The heat exchange and air supply assembly includes a fan and an evaporator. The air intake end of the fan is correspondingly set to the air inlet end of the refrigeration air duct, and the air outlet end of the fan is set at the front end of the evaporator. When the fan is running, the gas inside the cabinet passes through the fan and the evaporator to form cold air that returns to the cabinet.

[0015] The beneficial technical effects of this utility model are as follows: By using a fixed assembly with a built-in cooling duct as the overall frame, the compressor condenser assembly and heat exchange air supply assembly are integrated within this fixed assembly. Compared to traditional split-type installations, this integrated design significantly simplifies the installation process of the refrigeration unit and reduces installation complexity. Furthermore, due to the integration of core components, maintenance eliminates the need to search for parts in different locations within the freezer, greatly improving maintenance convenience. Moreover, this design rationally plans the space, avoiding the problem of traditional evaporator coil design and installation locations occupying a large amount of space, effectively increasing the effective volume of the freezer for product display, and breaking through the technical bottleneck of low space utilization in existing commercial refrigeration equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] See Figures 1-6 A refrigeration unit includes a fixed assembly 1 with a built-in refrigeration air duct 4, and a compressor condensing assembly 2 and a heat exchange air supply assembly 3 placed in the fixed assembly 1; The compressor condenser assembly 2 is located outside the refrigeration duct 4, and the heat exchange air supply assembly 3 is located inside the refrigeration duct 4, so that the compressor condenser assembly 2 and the heat exchange air supply assembly 3 are integrated in the fixed component 1 to form an integral refrigeration unit.

[0024] By using the fixed component 1 with the built-in cooling air duct 4 as the overall frame, the compressor condenser assembly 2 and the heat exchange air supply assembly 3 are integrated and set within the fixed component 1. Compared with traditional split installation, this integrated design significantly simplifies the installation process of the refrigeration unit and reduces installation complexity. At the same time, due to the integration of core components, there is no need to search for parts in different locations within the freezer cabinet during maintenance, greatly improving maintenance convenience. Furthermore, this design rationally plans the space, avoiding the problem of traditional evaporator coil design and installation location occupying a large amount of space, effectively increasing the effective volume of the freezer for product display, and breaking through the technical bottleneck of low space utilization in existing commercial refrigeration equipment.

[0025] The fixing component 1 has a mounting cavity 5, which is independently spaced from the refrigeration duct 4 within the fixing component 1. The compressor condenser assembly 2 is fixed within the mounting cavity 5. This structural design clearly divides the functional areas inside the refrigeration unit. The mounting cavity 5 provides stable fixation and protection for the compressor condenser assembly 2, preventing it from shaking during operation and affecting performance. Simultaneously, the independent arrangement of the mounting cavity 5 and the refrigeration duct 4 avoids airflow interference between them, ensuring that the heat generated by the compressor condenser assembly 2 does not affect the refrigeration airflow within the refrigeration duct 4. This guarantees the stability and refrigeration efficiency of the refrigeration system, effectively improving the overall performance of the refrigeration unit.

[0026] The mounting cavity 5 and the cooling air duct 4 are arranged vertically at intervals. This layout makes full use of the vertical dimension of the space and rationally allocates the internal space without increasing the horizontal footprint of the refrigeration unit.

[0027] The mounting cavity 5 is equipped with a heat dissipation window 6 and a vent 7. The compressor condenser assembly 2 is located between the heat dissipation window 6 and the vent 7. Both the heat dissipation window 6 and the vent 7 are connected to the external air of the mounting cavity 5, forming a heat dissipation channel for the compressor condenser assembly 2. This design can effectively guide external air into the mounting cavity 5, carry away the heat generated by the compressor condenser assembly 2 during operation, and exhaust it through the vent 7, ensuring that the compressor condenser assembly 2 is always within a suitable operating temperature range, avoiding performance degradation or malfunction due to excessive temperature.

[0028] The heat dissipation window 6 is equipped with a cooling fan for assisting the cooling of the compressor condenser assembly 2. External air enters the mounting cavity 5 through the cooling fan and is discharged from the mounting cavity 5 through the vent 7.

[0029] A cooling fan is installed on the heat dissipation window 6. Outside air enters the mounting cavity 5 through the cooling fan and is exhausted through the vent 7. The cooling fan further enhances the airflow speed, greatly improving the heat dissipation effect on the compressor condenser assembly 2. It can quickly and effectively dissipate the heat generated by the compressor condenser assembly 2, ensuring its stable operation. Even under high temperature or high load operating conditions, the cooling fan can maintain good heat dissipation performance, extending the service life of the compressor condenser assembly 2. At the same time, it enables the refrigeration unit to maintain efficient cooling under corresponding operating conditions, improving the reliability and practicality of the freezer.

[0030] The fixing component 1 includes a first frame cover 10, a refrigeration air duct 4 and a heat exchange air supply assembly 3 disposed inside the first frame cover 10, and a compressor condensing assembly 2 located on the top outer side of the first frame cover 10. The first frame cover 10 is provided with a second frame cover 11 for covering the compressor condensing assembly 2. An installation cavity 5 for installing the compressor condensing assembly 2 is formed between the second frame cover 11 and the first frame cover 10.

[0031] The fixed assembly 1 includes a first frame cover 10 and a second frame cover 11. This structural design facilitates the assembly and disassembly of the refrigeration unit. The compressor condenser assembly 2 is located on the top outer side of the first frame cover 10, and is enclosed by the second frame cover 11 to form the mounting cavity 5. This not only facilitates installation but also allows for quick disassembly of the second frame cover 11 for maintenance, improving maintenance efficiency. Simultaneously, the refrigeration air duct 4 and the heat exchange air supply assembly 3 are housed within the first frame cover 10, rationally planning the internal space and resulting in a compact refrigeration unit structure.

[0032] The second frame cover 11 has a ventilation opening 7 and a fixing bracket 12 on its side. The fixing bracket 12 has a heat dissipation window 6 for installing a cooling fan. The second frame cover 11 has an installation opening 13 for installing the fixing bracket 12. Alternatively, the second frame cover 11 and the fixing bracket 12 are integrally formed.

[0033] The second frame cover 11 has a vent 7, a mounting bracket 12, and a heat dissipation window 6 on its side. Whether the mounting bracket 12 is installed through the mounting opening 13 or through a one-piece design, it provides a good structural foundation for the heat dissipation of the compressor condenser assembly 2. This design can precisely guide airflow, working in conjunction with the cooling fan to form an efficient external heat dissipation circulation, ensuring the heat dissipation effect of the compressor condenser assembly 2. At the same time, the reasonable structural design ensures that all components are securely installed, providing users with a more comfortable user experience.

[0034] In this embodiment, ventilation openings 7 are provided on three sides of the second frame cover 11 to increase the air outlet area. The fixing frame 12 is provided with a number of heat dissipation windows 6 arranged linearly at intervals. The number of heat dissipation windows 6 are arranged at intervals along the length of the fixing frame 12 to increase the air inlet area and increase the heat dissipation effect.

[0035] In this embodiment, the fixing bracket 12 is embedded in the second frame cover 11 through the mounting opening 13, and the fixing bracket 12 is provided with an outward flange 12.1 fixed on the top of the outer frame cover 17.

[0036] The first frame cover 10 includes a bracket 9 for mounting the heat exchange air supply assembly 3. The heat exchange air supply assembly 3 includes a fan 14 and an evaporator 15. One end of the bracket 9 is provided with an inclined end 9.1 for mounting the fan 14. The bracket 9 is provided with a water receiving tray 9.2 for receiving the condensate from the evaporator 15. The water receiving tray 9.2 is provided with a drain outlet 9.3.

[0037] The inclined end 9.1 optimizes the installation angle of the fan 14, allowing it to better guide airflow and improve the air circulation efficiency within the cooling duct 4, thereby enhancing the cooling effect. The inclusion of the drip tray 9.2 and drain outlet 9.3 effectively solves the problem of condensate collection and discharge from the evaporator 15, preventing condensate buildup from damaging the internal structure of the refrigeration unit, ensuring the safety and reliability of the refrigeration unit's operation, and extending the equipment's service life.

[0038] The first frame cover 10 includes a frame cover 8 fixedly connected to the bracket 9. The bracket 9 covers the bracket 9 and encloses the evaporator 15. A cooling air duct 4 is formed between the frame cover 8 and the bracket 9. A gap 16 is left between the other end of the bracket 9 and the frame cover 8 to form an air outlet. The first frame cover 10 also includes an outer frame cover 17 fixedly connected to the frame cover 8. The outer frame cover 17 covers the frame cover 8, and the compressor condenser assembly 2 includes a compressor 18 and a condenser 19 fixedly on the top of the outer frame cover 17. The second frame cover 11 is fixedly connected to the outer frame cover 17.

[0039] The first frame cover 10 consists of a frame cover 8, a bracket 9, and an outer frame cover 17. This layered structural design not only clearly defines the installation space for the refrigeration air duct 4, the heat exchange air supply assembly 3, and the compressor condenser assembly 2, but also forms a reasonable airflow channel. The refrigeration air duct 4 is formed between the frame cover 8 and the bracket 9, ensuring smooth airflow; the gap 16 between the bracket 9 and the frame cover 8 forms an air outlet, optimizing the output direction and range of the cold air. At the same time, the outer frame cover 17 cooperates with the second frame cover 11 to securely install the compressor condenser assembly 2, ensuring that all components are firmly installed, the overall structure is compact, and effectively improves the performance and space utilization of the refrigeration unit.

[0040] In this embodiment, the bracket 9 is provided with a folded edge 9.4 that is fixedly connected to the inner side of the frame cover 8. The frame cover 8 is provided with a connecting edge 8.1, which is fixedly installed on the inner side edge of the opening of the outer frame cover 17. The frame cover 8 is embedded in the inner cavity of the outer frame cover 17.

[0041] A refrigeration cabinet includes a cabinet body, on which the aforementioned refrigeration unit is mounted; The refrigeration unit is installed on the top of the cabinet, and the air inlet and outlet of the refrigeration duct 4 are both connected to the inside of the cabinet. The heat exchange and air supply assembly 3 includes a fan 14 and an evaporator 15. The air intake end of the fan 14 is correspondingly set with the air inlet end of the cooling air duct 4, and the air outlet end of the fan 14 is set at the front end of the evaporator 15. When the fan 14 is running, the gas in the cabinet passes through the fan 14 and the evaporator 15 to form cold air that returns to the cabinet.

[0042] The refrigeration unit is located at the top of the cabinet, with both the air inlet and outlet of the refrigeration duct 4 connected to the interior of the cabinet. This layout creates a complete refrigeration cycle system inside the freezer. When the fan 14 is running, the gas inside the cabinet is cooled by the fan 14 and the evaporator 15, forming cool air that returns to the cabinet, ensuring the uniformity and stability of the temperature inside the cabinet and providing a good storage environment for the goods. At the same time, the application of the integrated refrigeration unit reduces the space occupied inside the freezer, greatly increasing the product display area, meeting the needs of commercial users for large-capacity display in freezers, and enhancing the commercial value and market competitiveness of the freezer.
