Description
Technical Field
[0001] This utility model relates to the field of air conditioning cooling technology, and in particular to a cold and hot aisle isolation and heat dissipation structure for a multi-split air conditioner outdoor unit. Background Technology
[0002] Currently, with social development, architectural styles are becoming increasingly diverse, and Chinese-style roofs are beginning to regain popularity in different regions. For example, the Jiageng-style buildings, which have been popular in Xiamen for a long time, combine Western-style architecture with Chinese-style roofs, becoming a scenic feature of this tourist city.
[0003] The installation of a traditional Chinese-style roof obstructs the flow of hot air from the rooftop, resulting in poor ventilation and reliance on side air intakes for air circulation. Since multi-split air conditioning units are typically located on the roof, the traditional Chinese-style roof design easily leads to heat buildup and reduced overall cooling efficiency. This decreased efficiency also causes the compressor to operate at a high load, generating significant noise. To improve ventilation, a solution has been implemented using numerous industrial fans for forced ventilation; however, this further increases noise and negatively impacts the working environment within the building. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cold and hot aisle isolation and heat dissipation structure for the outdoor unit of a multi-split air conditioner, thereby solving the problems of poor ventilation effect of existing Chinese-style roofs, which leads to reduced air conditioning cooling efficiency and high noise.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cold and hot aisle isolation and heat dissipation structure for a multi-split air conditioner outdoor unit, installed on the roof, for promoting airflow and heat dissipation of the air conditioner outdoor unit, comprising: An isolation mechanism is installed on the roof to divide the roof into a cold aisle and a hot aisle; the isolation mechanism has a fitting channel, and the outdoor unit of the air conditioner is installed in the fitting channel, so that the air outlet of the outdoor unit of the air conditioner is located in the hot aisle; Air guide mechanisms are installed at both ends of the cold and hot aisles to allow air to flow within them. The temperature measuring mechanism is installed in the cold and hot aisles and is electrically connected to the air guiding mechanism.
[0006] In one embodiment, the isolation mechanism includes an isolation bracket, an isolation top plate, and a sliding connecting plate; the isolation bracket is disposed at least at both ends of the isolation top plate, and the sliding connecting plate is slidably connected to the bottom of the isolation top plate, with the sliding connecting plate forming an interlocking channel.
[0007] In one embodiment, the sliding plate includes a fixed part and a telescopic part. The fixed part is slidably connected to the isolation top plate, and the telescopic part is disposed on the side of the fixed part near the outdoor unit of the air conditioner via a connecting component.
[0008] In one embodiment, the connecting assembly includes a fixed sliding sleeve, a telescopic spring, and a telescopic slider. The fixed sliding sleeve is fixed to the fixed part, the telescopic slider is embedded in the fixed sliding sleeve, and the telescopic spring is sleeved on the telescopic slider. The two ends of the telescopic spring are respectively connected to the end of the telescopic slider away from the telescopic part and the end of the fixed sliding sleeve close to the telescopic part.
[0009] In one embodiment, a limiting protrusion is provided at one end of the fixed sliding sleeve near the telescopic part; when the extension is reached to the limit, the end of the telescopic slider away from the telescopic part abuts against the limiting protrusion.
[0010] In one embodiment, each set of sliding plates has two fixed parts, and there is a gap between the two fixed parts to form a telescopic cavity. The connecting assembly is disposed in the telescopic cavity, and the telescopic part extends and retracts along the telescopic cavity.
[0011] In one embodiment, the bottom of the isolation top plate is provided with a groove, and the top of the fixing part is provided with a displacement slider, which slides back and forth along the groove.
[0012] In one embodiment, the isolation mechanism further includes a locking member, and the side wall of the slide groove is provided with a locking through hole, through which the locking member passes and abuts against the displacement slider.
[0013] In one embodiment, the air guiding mechanism includes an air guiding fan and a protective grille. The protective grille is disposed at both ends of the cold aisle and the hot aisle, and the air guiding fan is disposed on the protective grille.
[0014] In one embodiment, the temperature measuring mechanism is electrically connected to the air guide fan, and the air guide fan increases or decreases its speed according to the temperature signal transmitted by the temperature measuring mechanism.
[0015] The beneficial effects of this utility model are as follows: Due to the pursuit of aesthetic appeal in modern architecture, the design of traditional Chinese-style roofs often restricts roof ventilation. When multi-split air conditioning outdoor units are installed, the heat generated by the air conditioning system accumulates on the roof, reducing the overall cooling efficiency of the air conditioner and further causing the compressor to operate at a continuous high load, generating significant noise. While relying on industrial fans to accelerate airflow can dissipate heat, the large roof area necessitates a large number of fans, requiring overall airflow across the entire roof area to accelerate ventilation. The operation of numerous fans also generates noise, affecting the working or living environment within the building.
[0016] Therefore, this utility model divides the roof into separate cold and hot aisles by using an isolation mechanism. This allows most of the outdoor air conditioning unit to be located in the cold aisle, while the air outlet of the outdoor air conditioning unit is located in the hot aisle. This allows the air conditioning system to draw in air from the cold aisle and discharge hot air into the hot aisle during operation. By physically separating the hot air discharged from the outdoor air conditioning unit, the discharged hot air is prevented from re-entering the outdoor air conditioning unit, thereby improving energy efficiency and ensuring the cooling effect.
[0017] Furthermore, with the installation of the isolation mechanism, the roof area is completely divided into relatively independent channels. After the hot air from the outdoor unit of the air conditioner is discharged, due to space constraints, it will flow along the hot channel and then be guided out by the air guide mechanism. At the same time, the air guide mechanism can promote the entry of outside air into the cold channel, thus creating air circulation throughout the roof. Moreover, the air guide mechanism can control the airflow direction in the cold and hot channels, preventing the air discharged from the hot channel from being introduced into the cold channel, thereby ensuring the cooling effect of the air conditioning system and reducing noise generation.

[0023] Please refer to Figures 1 to 3 A cold and hot aisle isolation and heat dissipation structure for a multi-split air conditioner outdoor unit, installed on the roof, is used to promote airflow and heat dissipation of the outdoor unit 4, comprising: An isolation mechanism 1 is installed on the roof and divides the roof into a cold aisle 5 and a hot aisle 6. An interlocking channel 14 is provided on the isolation mechanism 1, and the outdoor air conditioner unit 4 is installed in the interlocking channel 14, so that the air outlet of the outdoor air conditioner unit 4 is located in the hot aisle 6. The air guide mechanism 2 is installed at both ends of the cold aisle 5 and the hot aisle 6 to allow air to flow in the cold aisle 5 and the hot aisle 6. Temperature measuring mechanism 3 is installed in cold aisle 5 and hot aisle 6 and is electrically connected to air guide mechanism 2.
[0024] While the isolation mechanism 1 can separate the roof, existing buildings, in pursuit of aesthetics and uniqueness, typically do not adopt standardized roof designs. This results in significant differences in roof height and size between different buildings, leading to substantial variations in the placement and installation location of the air conditioner outdoor unit 4. If the isolation mechanism 1 were a fixed design, it would be unable to accommodate the installation of the air conditioner outdoor unit 4 in different building types. Therefore, in this embodiment, the isolation mechanism 1 includes an isolation bracket 11, an isolation top plate 12, and a sliding connecting plate 13. The isolation bracket 11 is at least located at both ends of the isolation top plate 12, and the sliding connecting plate 13 is slidably connected to the bottom of the isolation top plate 12, forming a fitting channel 14. That is, the isolation mechanism 1 is installed according to the actual site conditions using a combination of the isolation bracket 11, the isolation top plate 12, and the sliding connecting plate 13, so that the sliding connecting plate 13 and the isolation top plate 12 form a fitting channel 14 for installing the air conditioner outdoor unit 4, thereby effectively enhancing the overall adaptability of the mechanism.
[0025] Preferably, the sliding plate 13 includes different lengths and widths. The longer sliding plate 13 can be used to contact the side of the outdoor unit 4, and the shorter sliding plate 13 can be used to contact the top of the outdoor unit 4. Those skilled in the art can adjust it as needed, without making specific limitations.
[0026] Preferably, the isolation mechanism 1 further includes an isolation cover plate, which is set at the top of the cold aisle 5. The isolation cover plate is perpendicular to the plane where the isolation top plate 12 and the sliding joint plate 13 are located, so that the isolation cover plate, the isolation top plate 12 and the sliding joint plate 13 form a semi-enclosed structure, further separating the cold aisle 5 and the hot aisle 6, and ensuring the normal operation of the outdoor unit 4 of the air conditioner.
[0027] Specifically, the isolation bracket 11 and the isolation top plate 12 can be adapted to the shape of the roof so that the roof space can be mostly divided.
[0028] Furthermore, if the highest point of the isolation top plate 12 and the isolation bracket 11 cannot reach the roof, the highest point of the isolation top plate 12 and the isolation bracket 11 must be higher than 3m. This arrangement can minimize the airflow in the cold aisle 5 and the hot aisle 6 through the space above the isolation top plate 12, thus ensuring the separation effect.
[0029] The sliding joint plate 13 needs to contact the outdoor unit 4 of the air conditioner to effectively isolate the airflow. However, the outdoor unit 4 vibrates during operation, and this vibration, when transmitted to the sliding joint plate 13, can easily cause it or the isolation top plate 12 to loosen. Therefore, the sliding joint plate 13 includes a fixed part 131 and a telescopic part 132. The fixed part 131 is slidably connected to the isolation top plate 12, and the telescopic part 132 is located on the side of the fixed part 131 near the outdoor unit 4 via a connecting assembly 133. By contacting the outdoor unit 4 with the telescopic part 132 and buffering the vibration, the vibration is prevented from being transmitted to the isolation top plate 12, thus improving the stability and service life of the overall structure. Furthermore, it can prevent additional noise caused by vibration between the outdoor unit 4 and the sliding joint plate 13, effectively improving the working environment.
[0030] In this embodiment, the connecting assembly 133 includes a fixed sliding sleeve 1331, a telescopic spring 1332, and a telescopic slider 1333. The fixed sliding sleeve 1331 is fixed to the fixed part 131, the telescopic slider 1333 is embedded in the fixed sliding sleeve 1331, and the telescopic spring 1332 is sleeved on the telescopic slider 1333. The two ends of the telescopic spring 1332 are respectively connected to the end of the telescopic slider 1333 away from the telescopic part 132 and the end of the fixed sliding sleeve 1331 close to the telescopic part 132. With this configuration, the telescopic slider 1333 overcomes the elastic force of the telescopic spring 1332 under the action of gravity and abuts against the outdoor unit 4 of the air conditioner. After the outdoor unit 4 of the air conditioner vibrates, it causes the telescopic slider 1333 to move up and down. At this time, the telescopic spring 1332 buffers the telescopic slider 1333, preventing the telescopic slider 1333 from directly colliding with the outdoor unit 4 of the air conditioner, thereby improving the overall stability and separation effect of the mechanism while effectively reducing noise.
[0031] Furthermore, when the sliding plate 13 adopts a long design, the bottom of the fixed part 131 abuts against the roof, and the telescopic part 132 is located on the side of the fixed part 131. In this case, a push spring 1335 is installed inside the fixed sleeve 1331. The elastic force of the push spring 1335 is slightly greater than that of the telescopic spring 1332, allowing the telescopic slider 1333 to abut against the side wall of the outdoor unit 4 under the action of the push spring 1335. When the outdoor unit 4 vibrates, the telescopic spring 1332 and the push spring 1335 work together to cushion the telescopic slider 1333.
[0032] In order to prevent the telescopic slider 1333 from coming out, in this embodiment, the fixed sleeve 1331 is provided with a limiting protrusion 1334 at one end near the telescopic part 132; when it is extended to the limit, the end of the telescopic slider 1333 away from the telescopic part 132 abuts against the limiting protrusion 1334.
[0033] In this embodiment, each set of sliding plates 13 has two fixing parts 131, and a gap between the two fixing parts 131 forms a telescopic cavity. The connecting assembly 133 is disposed in the telescopic cavity, and the telescopic part 132 extends and retracts along the telescopic cavity. This arrangement not only provides a telescopic cavity for the telescopic part 132, but also, during actual separation, the telescopic cavity blocks heat transfer through the air inside, preventing heat from being transferred from the sliding plates 13 to the cold channel 5, thus further enhancing the separation effect.
[0034] In this embodiment, the bottom of the isolation top plate 12 is provided with a sliding groove, and the top of the fixing part 131 is provided with a displacement slider, which slides back and forth along the sliding groove.
[0035] In this embodiment, the isolation mechanism 1 further includes a locking element 15. A locking through hole is provided on the side wall of the slide groove, and the locking element 15 passes through the locking through hole and abuts against the displacement slider. Specifically, the locking element 15 can be a bolt or a resilient pin, etc., and those skilled in the art can choose according to their needs without specific limitations.
[0036] In this embodiment, the air guiding mechanism 2 includes an air guiding fan 21 and a protective grille 22. The protective grille 22 is disposed at both ends of the cold aisle 5 and the hot aisle 6, and the air guiding fan 21 is disposed on the protective grille 22.
[0037] In this embodiment, the temperature measuring mechanism 3 is electrically connected to the air guide fan 21. The air guide fan 21 increases or decreases its rotation speed according to the temperature signal transmitted from the temperature measuring mechanism 3. Specifically, the temperature measuring mechanism 3 uses spaced temperature sensors to sense the temperature at different locations within the hot channel 6 and cold channel 5, and transmits the temperature signal to the air guide mechanism 2. When the temperature reaches different gradients, the air guide mechanism 2 adopts different rotation speed modes for dynamic adjustment, thereby reducing energy consumption while ensuring ventilation effect. Those skilled in the art can design the circuit according to actual conditions, without specific limitations.
[0038] Although this document uses terms such as isolation mechanism and air guiding mechanism frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
