Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.
[0044] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0045] See also Figure 1 In the first embodiment of the present application, an outdoor unit 10 is proposed for an inter-row air conditioner 20, which includes a casing 11, a condensing fan 12, a condenser 13 and a compressor 14; the casing 11 is the external structure of the outdoor unit 10, providing protection and support for the internal components. The condensing fan 12 is arranged at the top of the casing 11; specifically, the condensing fan 12 is installed at the top of the casing 11, responsible for driving air to flow through the condenser 13 to promote the heat exchange process. The condenser 13 is arranged in the casing 11, and the condenser 13 is located below the condensing fan 12; the condenser 13 is located inside the casing 11, and cooperates with the condensing fan 12, responsible for cooling the high-temperature and high-pressure gas compressed by the compressor 14 into a liquid state. The compressor 14 is connected to the condenser 13 and is disposed in the casing 11; the compressor 14 is also disposed in the casing 11 and is the heart of the air-conditioning system, responsible for circulating and pushing the refrigerant, and is connected to the condenser 13 to realize a refrigeration cycle.
[0046] Specifically, the present application frees up space for the inter-row air conditioner 20 and reduces internal complexity by deploying the compressor 14 in the outdoor unit 10. Moving the compressor 14 to the outdoor unit 10 directly frees up space for the indoor unit of the inter-row air conditioner 20. This not only reduces the size of the indoor unit, making its design more compact, but also simplifies the internal structure of the indoor unit because it no longer needs to accommodate the compressor 14, which means fewer internal components and simpler pipeline arrangements. The simplified internal structure not only helps to improve the reliability of the air-conditioning system, but also makes subsequent maintenance and service work more convenient. Maintenance work is mainly concentrated in the outdoor unit 10, which is easy to access and will not interfere with the normal operation of the data center. Maintenance personnel can inspect, maintain or replace the compressor 14 without entering the narrow interior of the data center, greatly improving maintenance efficiency.
[0047] Please refer to Figures 1 to 3 In some embodiments, the condenser 13 is set to be V-shaped; specifically, the V-shaped setting of the condenser 13 not only increases the air flow through the condenser 13 and improves the heat exchange efficiency, but also maximizes the use of the surface area of the condenser 13 in a limited space, thereby improving the overall cooling effect. The V-shaped opening is set toward the condensing fan 12, so that the wind blown by the fan can pass through the fins of the condenser 13 more directly. Such an airflow dynamics layout is conducive to the rapid dissipation of heat and further improves the cooling efficiency. It can be understood that since the V-shaped setting provides a larger surface area, the heat exchange is more efficient, which helps to quickly cool the high-temperature gas discharged from the compressor 14 into a liquid state, thereby improving the efficiency of the entire refrigeration system. It provides a larger heat exchange area than the traditional straight condenser 13 while occupying the same space. The setting of the opening toward the condensing fan 12 optimizes the path of air flowing through the condenser 13, reduces wind resistance, improves the working efficiency of the fan, and thus reduces the energy consumption of the system.
[0048] Specifically, the V-shaped condenser 13, through its unique structural design, ensures efficient heat exchange while also taking into account the optimization of space utilization. The V-shaped structure of the condenser 13 increases the air flow path, improves the time and efficiency of heat exchange, and also facilitates air circulation and heat dissipation, reducing the energy consumption required for the fan to work. In addition, the setting of the V-shaped condenser 13 is not only conducive to improving the cooling effect, but also makes the installation of the condenser 13 in the outdoor unit 10 more compact, leaving more space for the layout of other components and the conduct of maintenance work. Maintenance personnel can more easily access the components in the outdoor unit 10 for inspection, maintenance or replacement, further improving the maintainability and stability of the entire system.
[0049] Please continue to refer to Figures 1 to 3In some embodiments, the condenser 13 includes a first cold row 131 and a second cold row 132; the first cold row 131 has a first cold row end 133 and a second cold row end 134, and the second cold row 132 has a third cold row end 135 and a fourth cold row end 136; the top of the housing 11 has a first edge 111 and a second edge 112; the first cold row end 133 is connected to the first edge 111, and the third cold row end 135 is connected to the second edge 112; this connection method is conducive to the fixation and stability of the cold row, and also optimizes the flow path of the cooling air. The second cold row end 134 is connected to the fourth cold row end 136 as the fifth cold row end 137, which not only enhances the cooling effect, but also is more compact and efficient in structure. Specifically, by providing the first cold row 131 and the second cold row 132, the heat exchange area of the outdoor unit 10 is greatly increased, thereby improving the cooling efficiency.
[0050] Please continue to refer to Figures 1 to 3 In some embodiments, the housing 11 has a first side surface and a second side surface that are arranged opposite to each other; the first side surface is provided with a first crossbeam 113, and the second side surface is provided with a second crossbeam 114; by providing the first crossbeam 113 and the second crossbeam 114 on the first side surface and the second side surface of the housing 11, a solid foundation is provided for the stable support of the cold row. This arrangement is conducive to maintaining the fixed position of the cold row and ensuring the maximum heat exchange efficiency. The fifth end 137 of the cold row is connected to the first crossbeam 113 and the second crossbeam 114; the first crossbeam 113 and the second crossbeam 114 are connected to the first crossbeam 113, and the first crossbeam 113 and the second crossbeam 114 are connected to the second crossbeam 114. This connection method not only stabilizes the structure of the cold row, but also ensures the stability and efficiency of the cold row during operation. Among them, the first side surface is arranged close to the compressor 14, and the first crossbeam 113 is detachably connected to the housing 11. The detachable connection arrangement of the first crossbeam 113 and the housing 11 improves the convenience of maintenance and repair of the outdoor unit 10. When the radiator, compressor 14 or other internal components need to be replaced or maintained, the crossbeam can be easily removed to perform corresponding operations, which greatly reduces the complexity and time of maintenance.
[0051] Please refer to 1 and Figure 2In some embodiments, the outdoor unit 10 further includes an oil separator 15; the main function of the oil separator 15 is to separate most of the lubricating oil from the oil-containing gas discharged from the compressor 14, and then return it to the compressor 14 to ensure that the refrigerant contains as little lubricating oil as possible. This can reduce the oil film resistance when the refrigerant flows through the evaporator and the condenser 13, improve the heat exchange efficiency, and also avoid the potential damage of the lubricating oil to other components of the refrigeration system. The oil separator 15 is arranged in the housing 11, and the oil separator 15 is connected between the compressor 14 and the condenser 13 to ensure that the oil-containing gas discharged from the compressor 14 is processed by the oil separator 15 before entering the condenser 13, so as to effectively separate most of the lubricating oil.
[0052] Please continue to refer to 1 and Figure 2 In some embodiments, the outdoor unit 10 further includes a gas-liquid separator 16 and a liquid inlet; the gas-liquid separator 16 is disposed in the housing 11, and the liquid inlet is used for returning the cooling liquid; specifically, the main function of the gas-liquid separator 16 is to separate gas and liquid from the cooling liquid returning to the compressor 14, ensuring that only liquid cooling liquid enters the compressor 14, thereby preventing the compressor 14 from inhaling gas and causing a decrease in efficiency or damage. The gas-liquid separator 16 is connected between the liquid inlet and the compressor 14 to ensure that all cooling liquid returning to the compressor 14 must first pass through the gas-liquid separator 16, thereby effectively performing gas-liquid separation.
[0053] Please refer to Figure 4 and Figure 5In some embodiments, the outdoor unit 10 further includes an electric control box 17, and the electric control box 17 includes an outer flap 171 and a fixed side plate 172; the outer flap 171 and the fixed side plate 172 not only protect the internal electric control components from the influence of the external environment, but also facilitate the maintenance and repair work. The outer flap 171 is provided with a first folding edge 173, and the fixed side plate 172 is provided with a second folding edge 174. Specifically, the first folding edge 173 can be set to be L-shaped and the edge of the first folding edge 173 is folded toward the outer flap 171, and the first folding edge 173 extends along the edge of the outer flap 171, which not only increases the structural strength of the outer flap 171, but also effectively forms a groove. When rainwater or other liquid falls on the outer flap 171 of the electric control box 17, due to the groove formed by the L-shaped folding edge, the water flow will be guided into the groove, and then flow away along the groove in a directional manner, and finally discharged from the outside of the electric control box 17, effectively preventing moisture from entering the inside of the electric control box 17. The second fold edge 174 is set in an inverted L shape, which can provide additional coverage protection for the L-shaped first fold edge 173 on the outer flap 171. The inverted L-shaped second fold edge 174 extends outward and then bends downward to form a protective layer, increasing the level of rain protection. By setting the second fold edge 174 to cover the first fold edge 173, the possibility of rainwater directly entering the groove formed by the first fold edge 173 is greatly reduced even in a downpour. This stacked design creates an additional waterproof barrier, effectively guiding rainwater to flow away instead of allowing it to accumulate in the groove.
[0054] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the first folded edge 173 and the second folded edge 174 are not overlapped in the vertical direction. Specifically, the non-overlapping setting is to improve the convenience during maintenance. When opening or closing the outer flip cover 171 of the electric control box 17, the first folded edge 173 and the second folded edge 174 will not interfere with each other, making the operation easier and also reducing the damage to the first folded edge 173 and the first folded edge 174 caused by improper operation.
[0055] Please continue to refer to Figure 4 and Figure 5 In some embodiments, a sealing gasket 175 is provided between the outer flip cover 171 and the fixed side plate 172; specifically, the sealing gasket 175 is located between the outer flip cover 171 and the fixed side plate 172, which is the part most susceptible to external factors when the electric control box 17 is closed. The existence of the sealing gasket 175 can effectively block these potential external invasions; the sealing gasket 175 mainly provides a sealing function to prevent moisture, dust and other possible pollutants from entering the interior of the electric control box 17. It not only improves the waterproof performance of the electric control box 17, but also helps to maintain the cleanliness of the interior.
[0056] See also Figure 6 In the second embodiment of the present application, a row air conditioner 20 system is provided, which includes a row air conditioner 20 and an outdoor unit 10 as described above, and the row air conditioner 20 is connected to the outdoor unit 10. It can be seen that the row air conditioner 20 system has the advantages of simple wiring of the row air conditioner 20, easy maintenance and operation.
