[0002] Outdoor cabinet cooling technology is widely used in communications, data centers, power facilities, industrial control equipment and other fields. Cabinets face various harsh climatic conditions such as high temperature, low temperature, humidity changes, etc. in outdoor conditions. Modern communications and control equipment integrate a large number of electronic components, which generate heat during operation. If the heat of the equipment cannot be dissipated in time, the internal temperature will continue to rise, which may cause component aging, performance degradation or even failure, shortening the service life of the equipment. Effective cooling management can delay equipment aging and reduce maintenance costs.

[0003] The commonly used outdoor cabinet cooling technology currently mainly uses a special air conditioning system for precise temperature control, but this method generates high energy consumption. In addition, it can also be cooled through heat exchange technology, using lower temperature gas or coolant to cool the hot air inside the cabinet; but the traditional heat exchange system does not take into account the changes in external temperature differences in actual operation, does not monitor the temperature inside the cabinet and manage the cooling system, resulting in over-cooling or under-cooling when there is no effective monitoring and adjustment mechanism during long-term operation, which not only affects the normal operation of the equipment, but may also lead to energy waste and increase maintenance costs.

DETAILED DESCRIPTION

[0025] The accompanying drawings are only used for illustrative purposes and are not to be construed as limiting the present invention;

[0026] It is understandable to those skilled in the art that some well-known descriptions may be omitted in the drawings.

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1

[0029] This embodiment proposes an outdoor low-carbon uninterrupted circulation cabinet cooling device, such as Figure 1 As shown, it is a structural diagram of the outdoor low-carbon uninterrupted circulation cabinet cooling device of this embodiment.

[0030] The outdoor low-carbon uninterrupted cycle cabinet cooling device proposed in this embodiment comprises a cabinet 1 and an underground liquid cooling mechanism 2; the cabinet 1 is located above the underground liquid cooling mechanism 2, and the underground liquid cooling mechanism 2 is filled with coolant; the cabinet 1 is provided with an exhaust device 3, and the air inlet of the exhaust device 3 is arranged inside the cabinet 1, and the air outlet of the exhaust device 3 is connected to the air inlet of the underground air duct 4 in the underground liquid cooling mechanism 2, and the air outlet of the underground air duct 4 is connected to the air inlet of the first air duct 5 in the cabinet, and the air outlet of the first air duct 5 is located inside the cabinet;

[0031] The exhaust device 3 is provided with a first controller, and a first temperature sensor 102 is also provided inside the cabinet 1. The output end of the first temperature sensor 102 is connected to the input end of the first controller, and the first controller adjusts the power of the exhaust device according to the temperature data collected by the first temperature sensor 102; the exhaust device 3 extracts air from the inside of the cabinet 1 and sends it into the underground air duct 4 for cooling. The cooled air enters the first air duct 5 through the underground air duct 4 and is output to the inside of the cabinet 1.

[0032] In this embodiment, the air inlet of the exhaust device 3 is arranged inside the cabinet 1, and the hot air in the cabinet is first sucked in. The hot air sucked in by the exhaust device 3 enters the underground air duct 4 located in the underground liquid cooling mechanism 2; in the underground air duct 4, the air exchanges heat with the coolant in the cooling pool, and the temperature is reduced. The cooled air enters the first air duct 5 from the air outlet of the underground air duct 4. The air outlet of the first air duct 5 is located inside the cabinet, and the cooling air is re-delivered to the cabinet. A closed air circulation system is formed through continuous circulation, and the interior of the cabinet is continuously cooled. A first temperature sensor 102 is also arranged in the cabinet, and its output end is connected to the first controller. The first controller adjusts the power of the exhaust device according to the feedback of the temperature sensor to maintain a suitable temperature in the cabinet. Through the circulation system, hot air is continuously extracted and cooled, and cold air flows back into the cabinet, quickly reducing the temperature inside the cabinet to prevent the equipment from being affected by overheating or damaged. The air is cooled by using underground liquid cooling mechanism for heat exchange, without the need for additional refrigeration equipment, thus reducing energy consumption. Secondly, through the combination of the first temperature sensor and the first controller, real-time monitoring and automatic adjustment of the temperature inside the cabinet are achieved. According to the temperature change, the power of the exhaust device is automatically adjusted to ensure that the temperature inside the cabinet is always kept in the optimal range.

[0033] In an optional embodiment, the underground air duct 4 is placed in a spiral shape inside the underground liquid cooling mechanism 2 .

[0034] Further optionally, an air duct fixing column 6 is provided inside the underground liquid cooling mechanism 2 for fixing the underground air duct 4 , and both ends of the air duct fixing column 6 are fixed inside the underground liquid cooling mechanism 2 .

[0035] As an exemplary illustration, the coolant is an ethylene glycol solution.

[0036] In this embodiment, by arranging the underground air duct 4 in a spiral manner in the cooling pool, the contact area of ​​the underground air duct with the coolant in the coolant is significantly increased, so that the hot air can exchange heat with the coolant more fully in the air duct, thereby significantly improving the cooling effect of the air; secondly, the underground air duct 4 is fixed by the air duct fixing column 6 to prevent the underground air duct 4 from moving or shaking due to fluid impact or vibration in the coolant, thereby ensuring that the underground air duct 4 is always in the best position, and also avoiding wear, bending or rupture of the underground air duct 4 due to movement or friction, thereby extending the service life of the underground air duct 4 and reducing maintenance costs.

The cooled air enters the first air duct 5 through the underground air duct 4 and is output to the inside of the cabinet 1.

[0041] In an optional embodiment, the exhaust device 3 includes an exhaust fan 301, a second air duct 302 and a fan 303; the control end of the exhaust fan 301 is connected to the output end of the first controller; the air inlet of the second air duct 302 is placed inside the cabinet 1, and the air outlet of the second air duct 302 is connected to the air inlet of the exhaust fan 301; a fan 303 is provided at the air inlet of the second air duct 302 or in the duct.

[0042] Further optionally, a filter plate 101 is provided at the air inlet or the air outlet of the exhaust device 3 .

[0043] In this embodiment, the exhaust fan 301 operates under the control of the first controller to generate negative pressure, and the hot air inside the cabinet 1 is sucked to the exhaust fan 301 through the fan 303 and the second air duct 302. The hot air enters the underground air duct 4 after passing through the exhaust fan 301; secondly, the fan 303 is a passive device, which uses the airflow generated by the exhaust fan 301 to passively promote the flow of air inside the cabinet, reduce the resistance of air flow, prevent the backflow of airflow, and ensure that the hot air can be smoothly extracted. In addition, the air entering and leaving the cabinet is filtered through the filter plate to avoid the presence of dust, debris, etc.
