Description

Technical Field

[0001] The present invention relates to a network cabinet, in particular to an environment-friendly intelligent network cabinet with noise reduction, dehumidification and circulating cooling functions. Background Art

[0002] Network cabinets are crucial equipment in communications systems. They must possess excellent technical performance. The cabinet's structure should be physically and chemically designed based on the equipment's electrical and mechanical properties and the operating environment. This ensures the cabinet's structure offers excellent rigidity and strength, as well as excellent dehumidification, noise isolation, ventilation, and heat dissipation.

[0003] However, existing network cabinets generally use a fan structure for heat dissipation. The ambient temperature outside the cabinet will rise as the temperature inside the cabinet rises, ultimately reducing the heat dissipation capacity inside the cabinet. At the same time, the fan generates a lot of noise during the heat dissipation process. For example, when the external environment humidity is high, it is easy to affect the components inside the cabinet. Summary of the Invention

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown, the environmentally friendly intelligent network cabinet with noise reduction, dehumidification and circulating cooling functions in this embodiment includes a cabinet body 1, a box cover 2, a water tank 6, a water pump 61, a thermometer 62, a cold air nozzle 5, a wet curtain 7, a semiconductor refrigeration sheet 4 and a reaction box 83.

[0019] Among them, the cabinet body 1 is provided with a sealed box sleeve 2 on the outside, and a partition plate 3 is provided in the box sleeve 2 to divide the box sleeve 2 into two inner and outer chambers. An inner chamber 21 is formed between the partition plate 3 and the outer wall of the cabinet body 1, and an outer chamber is formed between the partition plate 3 and the inner wall of the box sleeve 2. A semiconductor refrigeration plate 4 is provided on the partition plate 3, and a heat sink 41 is provided on the heating surface of the semiconductor refrigeration plate 4. The heat sink 41 extends to the outer chamber, and a cooling plate 42 is provided on the cooling surface of the semiconductor refrigeration plate 4. The cooling plate 42 extends to the inner chamber 21. A cold air nozzle 5 is provided on the side wall of the cabinet body 1, and a water tank 6 is provided outside the cabinet body 1. A water pump 61 and a thermometer 62 are provided in the water tank 6. The outlet of the water pump 61 is connected to the top of the outer chamber through a pipeline, a return pipe 63 is connected between the bottom of the outer chamber and the water tank 6, and a connecting pipe 64 connected to the water tank 6 is provided at the bottom of the inner chamber.

[0020] Furthermore, in order to improve the heat dissipation capacity of the heat sink 41, a wet curtain 7 is provided in the outer chamber, and the heat sink 41 is embedded in the wet curtain 7. The structure of the wet curtain 7 reduces the speed of the water flowing downward in the outer chamber, increases the contact time between the water flow and the heat sink 41, and improves the temperature reduction ability of the heat sink 41.

[0021] Furthermore, in the embodiment of the present invention, in order to fully utilize the heat generated by the semiconductor refrigeration plate 4 during operation and avoid energy waste, a heat recovery device is designed. The heat recovery device can utilize the heat to make disinfectant. Specifically, Figure 2As shown, the outer chamber includes a left heat dissipation chamber 22 formed on the left side wall of the cabinet 1 and a right heat dissipation chamber 23 formed on the right side wall, the water tank 6 includes a left water tank 81 and a right water tank 82, a left water pump 811 is provided in the left water tank 81, the outlet of the left water pump 811 is connected to the top of the left heat dissipation chamber 22 through a pipeline, a left return pipe 813 is connected between the bottom of the left heat dissipation chamber 22 and the left water tank 81, a right water pump 821 is provided in the right water tank 82, the outlet of the right water pump 821 is connected to the top of the right heat dissipation chamber 23 through a pipeline, and a right return pipe 823 is connected between the bottom of the right heat dissipation chamber 23 and the right water tank 82. The left water tank 81 stores a sodium chlorate aqueous solution, and the right water tank 82 stores a hydrochloric acid aqueous solution. A left infusion pump 812 is provided in the left water tank 81, and the left infusion pump 812 is connected to a reaction box 83. A right infusion pump 822 is provided in the right water tank 82, and the right infusion pump 822 is connected to the reaction box 83 through a pipeline. A disinfectant delivery pump 831, a temperature controller and a thermometer are provided in the reaction box 83.

[0022] The present invention divides the outer chamber into two independent left heat dissipation chambers 22 and right heat dissipation chambers 23. The heat of the left heat dissipation chamber 22 is used to heat the sodium chlorate aqueous solution, and the heat of the right heat dissipation chamber 23 is used to heat the sodium chlorate aqueous solution. After the two aqueous solutions are heated to a specific temperature, the two aqueous solutions are mixed in a reaction box 83. In the reaction box 83, the sodium chlorate aqueous solution and the hydrochloric acid aqueous solution react at a certain temperature through negative pressure aeration to generate a mixed gas of chlorine dioxide and chlorine. After being absorbed by the absorption system, a chlorine dioxide mixed disinfectant with a certain concentration is formed.

[0023] In addition, in the embodiment of the present invention, in order to increase the flow rate and flow of cold air into the cabinet 1, the structure of the cold air nozzle 5 is designed. Specifically, Figure 3 As shown, the cooling air nozzle 5 includes a connecting pipe 51 connected to the inner chamber 21. A hemispherical nozzle 52 is disposed at the outer end of the connecting pipe 51. An airflow converging chamber 521 communicating with the connecting pipe 51 is formed within the hemispherical nozzle 52. A spherical body 53 is disposed within the hemispherical nozzle 52 to block the airflow converging chamber 521. An airflow gap 522 is formed between the spherical body 53 and the inner sidewall of the airflow converging chamber 521. A raised spherical surface 531 is formed on the outer surface of the spherical body 53. When the cooling air in the inner chamber enters the airflow converging chamber 521 through the connecting pipe 51 and is ejected from the airflow gap 522, the ejected airflow flows along the raised spherical surface 531 of the spherical body 53 and meets at the center of the raised spherical surface 531, forming a high-pressure airflow center at the center of the raised spherical surface 531. This achieves convergence and ejection of the cooling airflow, thus achieving targeted injection cooling within the cabinet 1.

[0024] Furthermore, in order to adjust the angle of the cold air ejected from the cold air nozzle, the hemispherical nozzle 52 is hinged to the outer end of the connecting pipe 51. In this way, by turning the hemispherical nozzle 52, the direction of the cold air ejected from the cold air nozzle can be changed.

[0025] Furthermore, in the embodiment of the present invention, the internal structure of the connecting pipe 51 is improved to realize the formation of a spirally rotating airflow in the airflow converging chamber 521. Specifically, Figure 4 As shown, a connecting nozzle is formed at the outlet of the connecting pipe 51. The connecting nozzle includes an upper conical port 511 and an inverted conical port 512. The upper conical port 511 and the inverted conical port 512 are connected to each other, and spiral groove walls are formed on the inner side walls of the upper conical port 511 and the inner side walls of the inverted conical port 512. After the airflow enters the connecting pipe 51, it first flows into the inverted conical port 512, forms a certain spiral diffusion, and then spirally converges in the upper conical port 511. In this way, when entering the airflow convergence chamber 521, a spiral airflow is formed. The spiral airflow is more conducive to flowing along the spherical surface of the inner side wall of the airflow convergence chamber of the hemispherical nozzle 52, achieving regular flow of the airflow in the airflow convergence chamber 521 and preventing the airflow from being disturbed in the airflow convergence chamber 521.

[0026] In summary, the present invention sets a box cover 2 outside the cabinet 1, and uses semiconductor ice sheets 4 in the box cover 2 to cool the air. The semiconductor ice sheets 4 are silent when working and do not generate noise. After the air is cooled, the water vapor in the air will condense on the heat sink 42. After the water droplets condense, they drip to the bottom of the inner chamber 21 and flow back into the water tank 6, dehumidifying the cold air entering the cabinet 1. At the same time, the heat generated by the semiconductor ice sheets 4 during the cooling process is accumulated on the heat sink 41. The water pump 61 in the water tank 6 pumps water into the top of the outer chamber. The water flows from the top of the heat sink 41 to the bottom and finally flows back into the water tank 6, forming a water cycle, thereby avoiding the external ambient temperature of the cabinet 1 from rising. At the same time, by designing a heat recovery device, the heat generated by the semiconductor ice sheets 4 can be utilized. While cooling the cabinet 1, disinfectant can also be produced, thereby avoiding heat waste and affecting the cabinet.
