Description

Technical Field

[0001] This utility model relates to the field of air-cooled unit technology, specifically an energy-saving high-temperature air-cooled box-type unit. Background Technology

[0002] Air-cooled box-type refrigeration units are highly efficient and energy-saving refrigeration equipment. Utilizing air-cooling technology, they eliminate the need for a cooling water system, simplifying installation and maintenance. With a compact structure and stable operation, these units are suitable for commercial buildings, data centers, industrial plants, and other similar locations. Through optimized heat dissipation design and an intelligent control system, they achieve efficient cooling and energy-saving operation, meeting cooling requirements under varying ambient temperatures. Featuring low noise, environmental friendliness, energy efficiency, and strong adaptability, they are an ideal choice for modern refrigeration systems.

[0003] However, it still has some drawbacks. For example, existing air-cooled box-type units, due to their fixed fan blade design, are difficult to adapt to seasonal changes. In winter, they still need to rely on forced ventilation mode, resulting in low energy efficiency. In low-temperature environments, their single operating mode cannot effectively utilize natural convection, leading to increased equipment wear and maintenance costs due to mechanical refrigeration throughout the year. This makes it difficult to meet modern energy-saving and environmental protection requirements and seriously restricts the performance of the unit under different operating conditions.

[0004] To address the aforementioned issues, this application proposes an energy-saving high-temperature air-cooled box-type unit. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving high-temperature air-cooled box-type unit to solve the problems mentioned in the background art, such as low energy efficiency, high maintenance costs, and inability to adapt to seasonal changes caused by the fixed fan blade design of existing air-cooled box-type units.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an energy-saving high-temperature air-cooled box-type unit, including an air-cooled box-type unit body. A dust filter is detachably mounted on the front of the air-cooled box-type unit body. An energy-saving self-folding fan device is installed inside the front of the air-cooled box-type unit body, and multiple sets of the energy-saving self-folding fan device are provided. The energy-saving self-folding fan device is interconnected with the dust filter. The energy-saving self-folding fan device facilitates seasonal intelligent adjustment through its unique blade folding function. During winter operation, the fan shaft remains stationary, and the foldable fan blades inside the device automatically retract, significantly increasing the ventilation cross-sectional area of ​​the air-cooled box-type unit body. This fully utilizes natural convection to achieve efficient cooling and reduces energy consumption. In summer, after the fan shaft rotates, the device automatically unfolds the foldable fan blades using a centrifugal force drive mechanism, forming a complete impeller structure to ensure heat dissipation performance. This device achieves year-round adaptive adjustment and seamless switching between natural ventilation in winter and mechanical cooling in summer. This not only optimizes the heat exchange efficiency of the equipment but also significantly improves energy utilization efficiency, resulting in significant energy-saving and environmental protection benefits.

[0007] Preferably, one side of the air-cooled box-type unit body is fixedly connected to a filter cleaning device, one side of the filter cleaning device is fixedly connected to a dual-motor linkage, and one side of the dual-motor linkage is equipped with a threaded rod, and there are two sets of threaded rods. The lower part of the air-cooled box-type unit body is fixedly connected to an installation strip, and there are two sets of installation strips.

[0008] Preferably, the other side of the threaded rod is movable inside the rod shaft, and the rod shaft is fixedly connected to one side of the air-cooled box-type unit body, while the threaded rod is movable inside the linkage plate.

Foldable fan blades are movable inside and on one side of the fixed fan blades, and the foldable fan blades are provided in multiple sets. The fixed fan blades and the foldable fan blades correspond to one set.

[0011] Preferably, the foldable fan blades are fixedly connected to folding hooks at the bottom, and each set of folding hooks has two sets. A spring-loaded fixing hook is fixedly connected to the lower part of the fixed fan blades, and each set of fixed fan blades has two sets of spring-loaded fixing hooks at the lower part of the interior. A retractable spring is installed between the folding hook and the spring-loaded fixing hook. When the energy-saving self-folding fan device is running, in summer, when the fan shaft of the energy-saving self-folding fan device starts to rotate, the centrifugal force drive mechanism causes the foldable fan blades to overcome the tension of the retractable spring and unfold outwards. The folding hook and the spring-loaded fixing hook... When the retractable spring is stretched, the foldable and fixed fan blades together form a complete impeller structure, achieving forced convection cooling. In winter, the fan shaft stops rotating, and the elastic restoring force of the retractable spring pulls the folding hook, causing the foldable fan blades to automatically retract into the fixed fan blades. At this time, the ventilation cross-sectional area increases significantly, utilizing natural convection to achieve efficient cooling. This device achieves seasonal adaptive adjustment through the automatic folding and unfolding of the fan blades, significantly improving natural ventilation efficiency in winter while ensuring heat dissipation performance in summer, thus achieving energy saving and consumption reduction.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4An energy-saving high-temperature air-cooled box-type unit includes an air-cooled box-type unit body 1. A dust filter 5 is detachably installed on the front of the air-cooled box-type unit body 1. An energy-saving self-folding fan device 6 is arranged in the inner cavity of the front of the air-cooled box-type unit body 1. The device adopts a multi-group parallel arrangement. The energy-saving self-folding fan device 6 and the dust filter 5 form an airflow channel. The energy-saving self-folding fan device 6 can achieve seasonal intelligent adjustment through its unique fan blade folding function. In winter operation, the fan shaft is stationary, and the foldable fan blades 8 inside the device automatically retract, significantly increasing the ventilation cross-sectional area of ​​the air-cooled box-type unit body 1, making full use of natural convection to achieve efficient cooling and reducing energy consumption. In summer operation, after the fan shaft rotates, the device uses a centrifugal force drive mechanism to automatically unfold the foldable fan blades 8 to form a complete impeller structure, ensuring heat dissipation performance. This device achieves year-round adaptive adjustment and seamless switching between natural ventilation in winter and mechanical cooling in summer. It not only optimizes the heat exchange efficiency of the equipment, but also greatly improves the energy utilization efficiency, and has significant energy-saving and environmental protection benefits.

[0021] In this embodiment, as shown Figures 1-2 As shown, the side wall of the air-cooled box-type unit body 1 is rigidly connected to the filter cleaning device 4. The filter cleaning device 4 is equipped with a linkage dual motor 41 at its end. The output end of the linkage dual motor 41 is connected to two sets of parallel threaded rods 42. Two sets of mounting strips 2 are welded to the bottom of the air-cooled box-type unit body 1. The ends of the threaded rods 42 are rotatably connected through rod shafts 43. The rod shafts 43 are fixed to the inner wall of the air-cooled box-type unit body 1. The threaded rods 42 pass through the linkage plate 31 to form a transmission fit. The two sets of linkage plates 31 are rigidly connected to the cleaning brush body 3. The working surface of the cleaning brush body 3 is provided with a brush layer 32. The brush layer 32 maintains a contact sliding fit with the surface of the dust filter 5.

[0022] In this embodiment, as shown Figures 3-4As shown, the energy-saving self-folding fan device 6 integrates multiple sets of fixed fan blades 7 around its frame. Each fixed fan blade 7 is equipped with a foldable fan blade 8. The bottom of the foldable fan blade 8 is connected to the retracting spring 9 via a folding hook 81. Each set of foldable fan blades 8 is equipped with two sets of folding hooks 81. The bottom of the inner cavity of the fixed fan blade 7 is provided with a corresponding spring fixing hook 71. The folding hook 81 and the spring fixing hook 71 are elastically connected via the retracting spring 9. When the energy-saving self-folding fan device 6 is running, in summer, when the fan shaft of the energy-saving self-folding fan device 6 starts to rotate, the centrifugal force drive mechanism causes the foldable fan blade 8 to overcome the tension of the retracting spring 9. When unfolded outwards, the retractable spring 9 between the folding hook 81 and the spring-fixed hook 71 is stretched. At this time, the foldable fan blade 8 and the fixed fan blade 7 together form a complete impeller structure, realizing forced convection heat dissipation. In winter, the fan shaft stops rotating, and the elastic restoring force of the retractable spring 9 pulls the folding hook 81, causing the foldable fan blade 8 to automatically retract into the fixed fan blade 7. At this time, the ventilation cross-sectional area is significantly increased, and efficient cooling is achieved by utilizing natural convection. This device achieves seasonal adaptive adjustment through the automatic folding and unfolding of the fan blades. While ensuring the heat dissipation performance in summer, it significantly improves the natural ventilation efficiency in winter, thereby achieving the effect of energy saving and consumption reduction.
