Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] like Figure 1-5The uninterruptible power supply (UPS) for a data center includes a hollow power supply housing 1. A panel assembly 16 is installed inside the power supply housing 1. A circulation side box 2 is installed on each side of the power supply housing 1. Two sets of internal through holes 3 are opened on both sides of the power supply housing 1. Two internal fans 4 are installed inside each of the two circulation side boxes 2. The two internal fans 4 are located on the outer wall of the power supply housing 1 at the outer end of the internal through holes 3. An internal heat exchange component is arranged between the two internal fans 4. An external heat exchange component is installed on the outer wall of the circulation side box 2 to cool the internal heat exchange component.

[0019] Furthermore, several casters 14 are installed at the bottom of the power supply housing 1 to facilitate the movement and transport of the power supply. A heat sink 15 is installed at the front and rear ends of the power supply housing 1. The surface of the heat sink 15 has undulating grooves to facilitate heat dissipation.

[0020] Furthermore, circulation side boxes 2 are provided on both sides of the power supply housing 1. The internal structure of the two circulation side boxes 2 is the same, so the internal structure of the circulation side boxes 2 on both sides is connected to the inside of the power supply housing through the internal through hole 3.

[0021] During operation, hot air inside the power supply housing 1 enters the circulation side box 2 corresponding to one of the sets of internal through holes 3. After the hot air absorbs heat through the internal heat exchange components inside the circulation side box 2, it becomes cold air and enters the area on the other side of the circulation side box 2. Then, it circulates back into the power supply housing 1 through another set of internal through holes 3 inside the circulation side box 2, thus completing the circulation of air inside the power supply housing 1.

[0022] The two internal fans 4 have opposite air intake directions. That is, inside the same circulating side box 2, one internal fan 4 is used to draw hot air from inside the power supply housing 1 into the circulating side box 2 through the inner through hole 3, and the other internal fan 4 delivers the cooled air inside the circulating side box 2 into the power supply housing 1 through the inner through hole 3.

[0023] The internal heat exchange component includes several guide plates 5 installed on the outer wall of the power supply housing 1. The several guide plates 5 are arranged horizontally and are equidistant from top to bottom. The guide plates 5 are arranged in a wave shape. Cooling plates 6 are fixedly installed at the outer ends of the several guide plates 5.

[0024] A slot 7 is provided on the outer wall of the circulating side box 2, and the cooling plate 6 is embedded in the slot 7. A curved airflow channel 8 is formed between two adjacent guide plates 5. The spaces of the circulating side box 2 located on both sides of the inner heat exchange component are connected through the airflow channel 8.

[0025] Based on the above, the airflow channels 8 are configured as multiple channels arranged side by side, and the outer side of the guide plate 5 is blocked by the cooling plate 6. Therefore, the airflow channel 8 formed between the guide plates 5 is a sealed gas flow channel.

[0026] When one of the internal fans 4 draws hot air from inside the power supply housing 1 into one side of the circulation side box 2, the other internal fan 4 will draw the hot air to the other side of the circulation side box 2. During this process, the hot air passes through the curved airflow channel 8 between the guide plates 5. The guide plates 5 also serve to absorb heat, absorbing the heat in the hot air and cooling it down. The cooled air is then circulated back into the power supply housing 1 through the internal through hole 3 on the other side by the other internal fan 4.

[0027] Furthermore, the guide vane 5 is wavy and the airflow channel 8 is curved. When hot air passes through, the flow path is increased and the residence time of hot air is prolonged. At the same time, during the flow, it continuously collides and contacts with the outer wall of the guide vane 5, so that the heat in the hot air can be effectively absorbed by the guide vane 5, accelerating the rate of air cooling.

[0028] The cooling element 6 is a semiconductor cooling element. The cold end of the semiconductor cooling element 6 is attached to the guide plate 5, while the hot end faces outwards towards the external heat exchange component. During operation, the cold end of the semiconductor cooling element 6 continuously cools the guide plate 5, further enhancing the cooling effect of the guide plate 5 on the hot air. Therefore, when the air inside the power supply housing 1 continuously circulates between the circulation side box 2 and the power supply housing 1, the air temperature can be significantly reduced. Simultaneously, although the air flows to the outside of the power supply housing 1 for circulation, it is actually still within the sealed space formed between the power supply housing 1 and the circulation side box 2, and does not come into contact with the external environment. Therefore, while achieving efficient heat dissipation, the overall sealing of the power supply structure is ensured, preventing external dust, moisture, and debris from entering the power supply, thus reducing the failure rate of the power supply equipment and improving operational stability.

[0029] Furthermore, the efficiency of the semiconductor cooling chip 6 is affected by the heat dissipation of the hot end portion. Therefore, an external heat exchange assembly is installed at the hot end portion of the cooling chip 6. The external heat exchange assembly includes an outer cover 9 fixed on the outer wall of the circulation side box 2. The cooling chip 6 is located inside the outer cover 9. An external fan 10 is also provided inside the outer cover 9. A gap is left between the external fan 10 and the cooling chip 6.

[0030] A connecting rod 11 for fixing is installed at the edge of the external fan 10. The other end of the connecting rod 11 is fixed to the outer wall of the circulation side box 2. Several first external through holes 12 are opened on the outer wall of the outer cover 9, and several second external through holes 13 are opened at the front and rear ends of the outer cover 9.

[0031] Based on the above, during the operation of the cooling chip 6, the external fan 10 operates, driving the gas flow, so that the external air enters the interior of the outer cover 9 through the first external through hole 12 on the outer cover 9, and acts on the hot end of the cooling chip 6 to cool the air. The air used for cooling flows to both sides through the gap between the external fan 10 and the cooling chip 6, and is discharged to the outside of the outer cover 9 through the second external through hole 13. The interior of the outer cover 9 is isolated from the circulation side box 2 by the cooling chip 6.

[0032] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
