With the continuous expansion of industrial production scale and the increasing demands for process precision and production efficiency in various fields, the power configuration and long-term operating load of centrifugal blowers are gradually increasing.

[0003] Previous high-efficiency cooling cabinets mostly used air cooling and water cooling or air-water cooling. However, air cooling is inefficient, water cooling requires an additional water chiller, which is bulky, inconvenient to transport, and requires additional power. Air-water chillers use an exhaust method that draws air from inside the cabinet. The hot air inside the cabinet is not conducive to cooling the circulating water. This method does not achieve the maximum cooling effect of the heat exchange device. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency cooling cabinet for fans, which solves the problem of low air-cooling efficiency.

[0005] To achieve the above objectives, this utility model provides a high-efficiency cooling cabinet for a fan, including an outer casing. A partition is fixedly installed between the top and bottom of the inner side of the outer casing. An air duct assembly is provided on the right side of the inner bottom of the outer casing. The air duct assembly includes an air inlet box, which is fixedly installed on the right side of the inner bottom of the outer casing. There are two air inlets, and air guide chambers are fixedly installed on the top of the two air guide chambers.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a high-efficiency cooling cabinet for a fan, including an outer casing 1. A partition 11 is fixedly installed between the top and bottom of the inner side of the outer casing 1. An air duct assembly 10 is provided on the right side of the bottom inside the outer casing 1. The air duct assembly 10 includes two air inlet boxes 103, which are fixedly installed on the right side of the bottom inside the outer casing 1. There are two air inlet boxes 103 in total. An air guide cavity 9 is fixedly installed on the top of the two air guide cavities 9. A Y-shaped connecting pipe 101 is fixedly installed on the top of the two air guide cavities 9. A secondary connecting pipe 102 is fixedly installed on the front side of each of the two air guide cavities 9. A main connecting pipe 104 is fixedly installed on the outer side, passing through the front side of the outer casing 1 and fixedly installed. A side connecting plate 4 is fixedly installed on the front side of the main connecting pipe 104. A motor body 8 is fixedly installed on the top left side of the outer casing 1. A cooling coil 12 is fixedly installed on the top of the motor body 8. The top of the cooling coil 12 passes through the top of the outer casing 1. A top connecting plate 6 is fixedly installed on the top of the cooling coil 12. A left connecting pipe 17 is fixedly installed on the top of the cooling coil 12, located in the center of the cooling coil 12. The other end of the left connecting pipe 17 passes through the side of the partition 11. The partition 11 fixedly installed between the top and bottom of the inner side of the outer casing 1 realizes the functional zoning of the internal space of the outer casing 1, providing a structural basis for the orderly operation of the cooling system. The air duct assembly 10, located on the bottom right side inside the outer casing 1, serves as the core of the airflow delivery system. Its two air inlet boxes 103 are fixed to the bottom right side inside the outer casing 1, used to draw in airflow or cooling medium from a designated area. The air guide cavity 9 fixed at the top of the air inlet box 103 guides and buffers the airflow, ensuring that the airflow drawn in by the air inlet box 103 smoothly converges to the Y-shaped connecting pipe 101. Through the diversion structure of the Y-shaped connecting pipe 101, the airflow is delivered to the two secondary connecting pipes 102. The main connecting pipe 104 fixed to the outside of the two secondary connecting pipes 102 serves as the airflow collection and output channel. Since the main connecting pipe 104 passes through the front side of the outer casing 1 and is fixedly installed, and a side connecting plate 4 is provided on the front side, a sealed connection with external airflow pipes or equipment can be achieved through the side connecting plate 4, ensuring the sealing and stability of the airflow delivery. Meanwhile, the motor body 8 fixed on the top left side of the outer casing 1 is the core working component of the cabinet. The cooling coil 12 fixed on its top penetrates the top of the outer casing 1 and is provided with a top connecting plate 6. The top connecting plate 6 can be used to connect the external cooling medium supply pipe, so that the cooling medium can enter the interior of the cooling coil 12. Through the direct contact between the cooling coil 12 and the motor body 8, the motor body 8 can be directly cooled. The left connecting pipe 17 at the center of the top of the cooling coil 12 penetrates the side of the partition 11, forming an airflow or medium flow channel between the cooling coil 12 and the space on the other side of the partition 11, providing path support for the circulation operation of the cooling system.

[0023] like Figures 1 to 5As shown, a left flange 18 is fixedly installed on the right side of the top end of the left connecting pipe 17, and a right flange 19 is fixedly installed on the left side of the top end of the Y-type connecting pipe 101. A fixing bolt 13 is screwed through the side of the partition plate 11, and the fixing bolt 13 is screwed through the inside of the left flange 18 and the right flange 19 for fixed connection. A heat exchanger 15 is fixedly installed inside the outer casing 1. The heat exchanger 15 is located behind the motor body 8. A protective net 16 is fixedly installed on the outside of the heat exchanger 15. The front and rear sides of the outer casing 1 are rotatably connected to the main cabinet door 5. The left and right sides of the outer casing 1 are rotatably connected to the side cabinet door 2. Ventilation openings 3 are opened on the sides of the side cabinet door 2 and the main cabinet door 5. An observation opening 7 is opened on the top of the side of the rear main cabinet door 5. An air guide 14 is fixedly installed on the inside of the right side cabinet door 2. The air guide 14 is located inside the ventilation opening 3. The air intake face of the air inlet box 103 faces the air guide 14. The left flange 18 on the right side of the top of the left connecting pipe 17 and the right flange 19 on the left side of the top of the Y-type connecting pipe 101 are sealed and fixedly connected by a fixing bolt 13 threaded through the side of the partition 11. This connection method not only ensures the airflow or medium transportation between the left connecting pipe 17 and the Y-type connecting pipe 101, but also facilitates disassembly and maintenance, so that the airflow channel of the air duct assembly 10 and the cooling coil 12 forms a complete closed loop, ensuring that the cooling airflow or medium can circulate orderly between the various pipe assemblies. The heat exchanger 15, which is fixedly installed inside the outer casing 1 on the rear side of the motor body 8, is the core component of heat exchange and is used to realize the heat exchange between the high-temperature airflow inside the cabinet and the cooling medium or the low-temperature airflow outside. The protective net 16 fixed on its outside can effectively block impurities from entering the interior of the heat exchanger 15, so as to avoid affecting the heat exchange efficiency or causing damage to the components. The main cabinet door 5, which is rotatably connected to the front and rear sides of the outer casing 1, and the side cabinet doors 2, which are rotatably connected to the left and right sides, facilitate the inspection and maintenance of the internal components of the cabinet. They also create an airflow exchange channel between the inside and outside of the cabinet through the ventilation openings 3 on the sides, enabling the air to circulate inside the cabinet. The air guide 14, which is fixedly installed on the inside of the right side cabinet door 2 and located inside the ventilation opening 3, guides the external airflow through the ventilation opening 3 and the air guide 14 to accurately enter the air intake box 103, thereby improving the intake efficiency of the air intake box 103 and avoiding airflow turbulence. The observation port 7 on the top side of the rear main cabinet door 5 allows for real-time observation of the operating status of the internal components, facilitating timely fault detection. External airflow enters through the ventilation ports 3 of the side cabinet door 2 and the main cabinet door 5, and is drawn into the air intake box 103 under the guidance of the air guide port 14. It is then transported through the air duct formed by the air guide cavity 9, the Y-shaped connecting pipe 101, the secondary connecting pipe 102, and the main connecting pipe 104. Finally, it enters the left connecting pipe 17 through the sealed connection between the left flange 18 and the right flange 19, and finally cooperates with the cooling coil 12 and the heat exchanger 15 to achieve efficient cooling of the motor body 8 and the internal space of the cabinet. At the same time, the airflow is discharged and circulated through the ventilation port 3 to ensure that the cabinet is continuously in a stable operating temperature environment.

[0024] Working principle: First, the external airflow enters through the ventilation openings 3 of the left and right side cabinet doors 2 and the front and rear main cabinet doors 5 of the outer casing 1. Under the directional guidance of the air guide 14 inside the right side cabinet door 2, it accurately converges into the two air inlet boxes 103 of the bottom right side air duct assembly 10 inside the outer casing 1. The airflow drawn in by the air inlet box 103 is smoothly guided to the Y-shaped connecting pipe 101 through the top air guide cavity 9. The Y-shaped connecting pipe 101 is then split into two secondary connecting pipes 102, and then converges into the main connecting pipe 104 that runs through the front side of the outer casing 1. The main connecting pipe 104 can be sealed to the external pipeline through the front side connecting plate 4 to ensure the stability of airflow delivery. At the same time, the Y-shaped connecting pipe 101 is aligned with the left flange 18 of the top left side connecting pipe 17 of the cooling coil 12 through the right flange 19, with the help of the partition 1. The fixing bolts 13 on the side achieve a sealed connection, allowing airflow to smoothly enter the left connecting pipe 17 and be delivered to the cooling coil 12. The cooling coil 12 is connected to the external cooling medium through the top connecting plate 6. The cooling medium circulates in the coil and, in conjunction with the direct contact between the cooling coil 12 and the motor body 8 on the top left side of the outer casing 1, directly cools the motor body 8. In addition, the heat exchanger 15 on the rear side of the motor body 8 inside the outer casing 1 works in conjunction with the cooling system to achieve heat exchange between the high-temperature airflow and the cooling medium inside the cabinet. The protective net 16 on the outside of the heat exchanger 15 blocks impurities to ensure heat exchange efficiency. Finally, the airflow that has completed the heat exchange is discharged through the ventilation port 3, forming a complete circulation process. At the same time, the internal operating status can be monitored in real time through the observation port 7 of the rear main cabinet door 5 to ensure that the cabinet is continuously in a stable operating temperature environment.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
