Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1-5 As shown, the present invention discloses an active cooling beam structure, comprising a housing 1, wherein the housing 1 includes a cooling beam coil 2 and a nozzle assembly 3. The cooling beam coil 2 is obliquely disposed inside the housing 1. A water inlet pipe 4 and a water return pipe 5 are provided on one side of the cooling beam coil 2, and the water inlet pipe 4 and the water return pipe 5 extend out of the housing 1 along its width direction. A primary air inlet 6 and a drain outlet 7 for discharging condensate from the housing 1 are provided on one side of the housing 1 along its width direction. A return air outlet 8 is provided on one side of the housing 1 along its length direction, and an air supply outlet 9 is provided at the bottom of the housing 1.

[0025] During operation, external air (fresh air) is introduced through the primary air inlet 6 and enters the interior of the casing 1. The cooling coil circulates chilled water through the water inlet pipe 4 and the return water pipe, using the chilled water to cool the air and regulate its temperature. When the air flows through the nozzle assembly 2, a pressure difference is generated, forming a high-speed jet that provides strong power for the air supply. At the same time, it induces the return air to mix, achieving effective air mixing. The mixed air is then delivered into the room through the air outlet 9, achieving temperature and humidity regulation of the indoor air. This structural design improves the efficiency of airflow and heat exchange, while optimizing the comfort of the indoor environment. Furthermore, the cooling coil 2 is installed at a certain angle, which has better drainage performance, reduces condensate backflow, and can improve heat exchange efficiency to a certain extent. It also helps guide air to pass through the cooling coil more evenly, reducing dead zones and short-circuit phenomena.

[0026] Furthermore, the outer shell 1 includes an upper shell 11 and a lower shell 12. Positioning blocks 111 are provided around the bottom perimeter of the upper shell 11, and positioning grooves 121 are provided around the top perimeter of the lower shell 12. The upper shell 11 and lower shell 12 are fastened together and connected by fasteners. The fastening design of the upper shell 1 and lower shell 2, along with the fastener connection, enhances the stability and sealing of the cold beam structure. The use of positioning blocks 111 and positioning grooves 121 simplifies the installation process, improves installation accuracy and efficiency, and reduces maintenance difficulty. Simultaneously, the modular design of the upper shell 11 and lower shell 12 facilitates installation, disassembly, and maintenance, reducing subsequent operating costs. Furthermore, both the upper shell 11 and lower shell 12 are provided with insulation layers. These insulation layers reduce heat loss, improve insulation efficiency, and simplify installation. Moreover, the integrated design of the insulation layer and the cold beam structure avoids the thermal bridge effect between the insulation layer and the pipes in traditional cold beam systems, further reducing heat loss.

[0027] In this embodiment, the lower shell 12 is provided with an inclined support frame 10 for supporting the cold beam coil 2 and a mounting groove 13 for mounting the nozzle assembly 2 on its inner side. The inclined support frame 10 and mounting groove 13 on the inner side of the lower shell 2 provide stable support for the cold beam coil and the nozzle assembly, ensuring the stability and reliability of the structure. This design helps to improve the durability and service life of the cold beam.

[0028] In addition, a condensate recovery tank 4 is provided inside the lower shell 12 at the lowest end of the inclined support frame 10. The water in the condensate recovery tank 14 is discharged as condensate through the drain outlet 7. The condensate recovery tank 13 is provided at the lowest end of the inclined support frame 10, and the condensate is discharged through the drain outlet 7, which effectively prevents the accumulation and backflow of condensate, reduces potential corrosion and bacterial growth problems, and improves the hygiene and safety of the system.

[0029] Preferably, the condensate recovery tank 14 includes a first collection tank 141 and a second collection tank 142, which are arranged in a stepped manner, and the second collection tank 142 is connected to the drain outlet 7.

[0030] In this embodiment, the upper shell 11 has upper stepped fastening surfaces 112 on both sides, and the lower shell 2 has lower stepped fastening surfaces 122 on both sides. When the upper shell 11 and the lower shell 12 are fastened together, the upper stepped fastening surfaces 112 and the lower stepped fastening surfaces 122 abut against each other. The stepped fastening surface design of the upper shell 11 and the lower shell 12 enhances the sealing performance of the outer shell 1 and the stability of the overall structure, while simplifying the fastening process and reducing the assembly difficulty.

[0031] Furthermore, the upper stepped engagement surface 112 is provided with an upper groove, and the lower stepped engagement surface 122 is provided with a lower groove. The upper and lower grooves form a through hole to accommodate the inlet pipe 4 and the outlet pipe 5. The through hole design formed by the upper and lower grooves provides a stable channel for the inlet pipe 4 and the outlet pipe 5, reduces the vibration and noise of the water pipes, and simplifies the installation and maintenance of the water pipes.

[0032] In this embodiment, there are at least two air outlets 9, which are arranged side by side on the side of the outer casing 1 along its length.

[0033] Furthermore, the nozzle assembly 3 includes a substrate 31 and a plurality of nozzles 32, which are arranged side by side at equal intervals on the substrate 31. The substrate 31 and the equally spaced nozzles 32 of the nozzle assembly 3 achieve uniform air distribution and high-speed jet, thereby improving air mixing efficiency and temperature control accuracy.

[0034] Preferably, the total area of ​​the nozzles is proportional to the area of ​​the return air inlet, resulting in a fresh air / return air induction ratio of 1:4. By designing the size and number of nozzles 32, the total area of ​​the nozzles 32 is proportional to the area of ​​the bottom return air inlet 8, utilizing the Venturi effect to achieve a fresh air induction ratio of 1:4. Setting this fresh air induction ratio optimizes the mixing efficiency of primary and return air. By accurately calculating the area ratio of the nozzles and the return air inlet, the uniformity and efficiency of air conditioning are improved.

[0035] In this embodiment, the cold beam coil 2 adopts a four-pipe coil structure to achieve simultaneous hot and cold water supply for precise regulation of ambient temperature and humidity. Furthermore, the four-pipe coil structure can meet the diverse temperature and humidity settings of different rooms, achieving personalized and comfortable adjustments. Based on the cold beam in this embodiment, indoor air quality is significantly improved, while maintenance and operation convenience are optimized, resulting in a green, efficient, and comfortable indoor environment.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
