Detailed implementation manners

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

[0018] Embodiment: Reference Figures 1 to 5 , a defrosting type communication equipment box adaptable to a relatively cold environment, including a box body 1 and an installation cavity 2 arranged in the box body 1. A communication device is arranged in the installation cavity 2. At least one air inlet 3 and an air outlet 4 communicating with the installation cavity 2 are respectively arranged on the box body 1. A fan assembly 5 and a one-way ventilation assembly 6 are arranged at both the air inlet 3 and the air outlet 4 of the box body 1. The one-way ventilation assembly 6 arranged at the air inlet 3 can enable the outside air to only enter the box body 1, and the one-way ventilation assembly 6 arranged at the air outlet 4 can enable the air in the box body 1 to only be discharged from the box body 1. An air inlet channel 7 communicating with the air inlet 3 and the installation cavity 2 is arranged in the box body 1. A plurality of heating assemblies 8 and a molecular sieve desiccant 9 for separating water vapor in the air are uniformly attached and fixedly connected to the side wall of the air inlet channel 7. A regeneration assembly 10 for automatically separating the moisture in the used molecular sieve desiccant 9 and discharging it outside the box body 1 is further arranged in the air inlet channel 7. The used molecular sieve desiccant 9 is heated and regenerated by the regeneration assembly 10 by the heating regeneration method, which improves the service life and reduces the maintenance cost.

[0019] Reference Figure 1 and Figure 5, specifically, the unidirectional ventilation component 6 includes a mounting seat 61 fixedly connected to the box body 1 and a closing plate 63 rotatably connected to the mounting seat 61 based on a torsion spring 62 for closing the mounting seat 61. A flexible gasket 64 is adhesively and fixedly connected to the circumferential side wall of the closing plate 63. A limiting block is fixedly connected to the mounting seat 61. When air passes through the mounting seat 61 in the forward direction at a certain speed, the closing plate 63 is lifted, and the torsion spring 62 is compressed. When the air stops flowing, the torsion spring 62 drives the closing plate 63 to reset to close the mounting seat 61. When the air passes through the mounting seat 61 in the reverse direction, the closing plate 63 is blocked by the limiting block to prevent air flow, and the flexible gasket 64 is used to improve the sealing effect.

[0020] Reference Figures 2 to 4, Specifically, the box body 1 includes a housing 11 and a positioning and fixing seat 12 fixedly connected inside the housing 11 for fixedly installing the installation cavity 2. There are 3 positioning and fixing seats 12, which are respectively arranged on the two right-angle sides at the bottom and the right-angle side at the top of the housing 11, and are fixedly arranged inside the housing 11 in a right-angled triangle structure. The installation cavity 2 is fixed on the positioning and fixing seat 12 by screws. A closing door 13 for closing the housing 11 is rotatably connected to the housing 11, and a magnetic absorption closing plate 14 for closing the installation cavity 2 is fixedly connected to the closing door 13, thereby realizing the sealing of the installation cavity 2 and the isolation between the installation cavity 2 and the air inlet channel 7. A sealing strip 15 is fixedly arranged on the closed surface of the housing 11 to improve the sealing effect. There are 3 groups of positioning and fixing seats 12, dividing the space between the housing 11 and the installation cavity 2 into 1 air inlet cavity 16 and 2 air outlet cavities 17. The air inlet 3 is opened in the air inlet cavity 16, and the air outlet 4 is opened in the air outlet cavity 17. The air inlet channel 7 includes a partition plate 71 fixedly connected inside the air inlet cavity 16 and having an L-shaped structure. The partition plate 71 divides the air inlet cavity 16 into an upper air inlet duct 72 and a lower air inlet duct 73 having an L-shaped structure. The upper air inlet duct 72 and the lower air inlet duct 73 are connected through a one-way ventilation component 6 arranged along the horizontal direction. The molecular sieve desiccant 9 is fixedly connected to the vertical part inside the upper air inlet duct 72. The air inlet 3 is opened at the bottom of the upper air inlet duct 72. The fan component 5 arranged at the air inlet 3 sucks the outside air into the air inlet duct. During the flow in the air inlet duct, the air is continuously heated by the heating component 8. When the air passes through the molecular sieve desiccant 9, the moisture in the air is separated. The dry hot air enters the installation cavity 2 to promote the evaporation of the water vapor in the installation cavity 2, and the evaporated moist air is extracted by the fan component 5 arranged at the air outlet 4, thereby realizing the replacement of the moist water vapor in the installation cavity 2 with hot air at a certain temperature, so that the communication equipment box can adapt to a colder environment and at the same time avoid the condensation of the moist water vapor in the installation cavity 2 from damaging the components. A wind adjustment plate 74 for adjusting the air inlet direction is rotatably connected to the end of the air inlet channel 7. Through the wind adjustment plate 74, the dry hot air can enter the installation cavity 2 in an inclined upward manner. Since the air outlets 4 are respectively arranged at the bottom and the top of the housing 11, the hot air flows upward and accumulates at the top of the installation cavity 2. With the continuous input of the dry hot air, the hot air spreads downward to replace the moist water vapor in the installation cavity 2. The fan component 5 arranged at the air outlet 4 can suck out the moist water vapor in the installation cavity 2, improving the heating efficiency in the installation cavity 2.

[0021] Reference Figures 2 to 4, specifically, the regeneration component 10 includes a lower mounting plate 101 and an upper mounting plate 102 fixedly connected in the upper air inlet duct 72 and respectively arranged at the bottom and top of the molecular sieve desiccant 9. A lower heating wire 103 and an upper heating wire 104 are fixedly connected to the lower mounting plate 101 and the upper mounting plate 102 respectively. A plurality of exhaust holes 105 are formed in the upper mounting plate 102, and an exhaust port 106 communicating with the exhaust holes 105 is formed at the top of the housing 11. A one-way ventilation component 6 is fixedly connected at the exhaust port 106. The heating temperature of the lower heating wire 103 is between 240 - 300 °C, and the heating temperature of the upper heating wire 104 is between 180 - 240 °C. The single heating regeneration duration is between 3 - 6 hours. When the molecular sieve desiccant 9 adsorbs a certain amount of water vapor, resulting in a reduction in the water vapor adsorption effect, the fan component 5 arranged at the air inlet 3 sucks in external air into the air inlet duct, and at the same time, the fan component 5 arranged at the air outlet 4 stops exhausting. The upper heating wire 104 and the lower heating wire 103 arranged on the upper mounting plate 102 and the lower mounting plate 101 heat the molecular sieve desiccant 9. Since the one-way ventilation component 6 is arranged between the upper air inlet duct 72 and the lower air inlet duct 73 and the fan component 5 at the air outlet 4 stops exhausting, the air entering from the air inlet 3 is heated and then passes through the molecular sieve desiccant 9 and is discharged through the exhaust holes 105 and the exhaust port 106. Through heating regeneration for a certain period of time, the water vapor adsorbed in the molecular sieve desiccant 9 is desorbed and released and discharged from the housing 11, realizing the continuous use of the molecular sieve desiccant 9 and reducing the maintenance cost and complexity.

[0022] Reference Figures 2 to 4, Specifically, the heating component 8 includes a heating plate 81 adhesively and fixedly connected to the inner wall of the air inlet passage 7, and heat dissipation fins 82 covering and arranged on the surface of the heating plate 81 for accelerating heat dissipation and ensuring uniform heat distribution. A humidity sensor 200 is fixedly connected to the end of the air inlet passage 7. A temperature sensor 100 and a humidity sensor 200 are fixedly connected in the installation cavity 2. A controller is fixedly connected to the top of the box body 1. The controller is coupled to the temperature sensor 100, the humidity sensor 200, the fan assembly 5, the heating component 8, and the regeneration component 10. When the temperature sensor 100 and the humidity sensor 200 in the installation cavity 2 detect that the temperature in the safety cavity is relatively low or the humidity is relatively high with a risk of frosting, the controller controls the fan assembly 5 and the heating component 8 to operate to heat up the installation cavity 2 and discharge the moist water vapor in the installation cavity 2. When the humidity sensor 200 arranged at the end of the air inlet passage 7 senses that the humidity of the hot air is relatively high, it controls the regeneration component 10 to operate to heat and regenerate the molecular sieve desiccant 9. The heating plate 81 uses a PTC ceramic heating plate 81. PTC has the characteristics of constant temperature heating, safety and reliability, and high heat conversion efficiency (up to more than 95%). By arranging heat dissipation fins 82 on the surface of the heating plate 81, the heat dissipation efficiency is improved, enabling the air to be heated faster.

[0023] Brief description of the usage process: The fan assembly 5 arranged at the air inlet 3 sucks the outside air into the air inlet duct. During the flow in the air inlet duct, the air is continuously heated by the heating component 8. When the air passes through the molecular sieve desiccant 9, the moisture in the air is separated. The dry hot air enters the installation cavity 2 to promote the evaporation of the water vapor in the installation cavity 2, and the evaporated moist air is extracted through the fan assembly 5 arranged at the air outlet 4, so as to replace the moist water vapor in the installation cavity 2 with hot air at a certain temperature, enabling the communication equipment box to adapt to a relatively cold environment and avoiding damage to the components caused by the condensation of the moist water vapor in the installation cavity 2.
