[0002] The distribution cabinet is the final equipment of the power distribution system, which is used for power supply and control of various electrical equipment. When the distribution cabinet is in use, its internal components will generate a certain amount of heat, especially during the peak period of electricity consumption in summer. When the electronic components inside the distribution cabinet are running at high load, the internal temperature of the distribution cabinet will rise sharply. The high temperature will damage the components inside the distribution cabinet. If the overheating problem is not effectively controlled, it may also cause safety hazards such as fire. Therefore, many distribution cabinets are equipped with circulating cooling water for cooling. However, since the cooling water is recycled, the temperature of the cooling water will rise after multiple coolings, which will reduce the heat displaced from the inside of the distribution cabinet and reduce the cooling effect of the equipment. In view of this, we propose a modular automatic cooling distribution cabinet. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Distribution cabinets play an indispensable role in industrial production, computer rooms, hospitals, commercial buildings, data centers and other occasions. They require continuous power distribution and management. These operations will generate a lot of heat. If the heat is not dissipated in time, the temperature inside the distribution cabinet will gradually rise, which may cause the distribution cabinet to overheat. Overheating will not only affect the normal operation of the distribution cabinet and reduce its work efficiency, but more importantly, overheating will damage the components inside the distribution cabinet and shorten its service life. The circulating cooling water used for cooling in the existing distribution cabinet will also reduce its cooling effect after multiple cooling. In order to suppress the rise in the temperature of the circulating cooling water and improve the cooling effect of the distribution cabinet, we proposed the following solution.

[0022] Embodiment 1

[0023] Reference Figure 1-Figure 4 A modular automatic cooling power distribution cabinet is mainly composed of a power distribution cabinet body 1 and a cooling component 2 with high efficiency heat dissipation inside the power distribution cabinet body 1. The power distribution cabinet body 1 is provided with a temperature sensor for detecting the internal temperature and a controller electrically connected to the temperature sensor, and the controller is electrically connected to the cooling component 2. When the temperature in the power distribution cabinet body 1 rises to a set value, the temperature sensor will transmit the value to the controller, and at this time the controller will control the cooling component 2 to operate, thereby realizing the operation of heat dissipation of the power distribution cabinet body 1.

[0024] When the power distribution cabinet is in operation, its internal components will generate a large amount of heat. If this heat is not dissipated in time, it may cause the power distribution cabinet to overheat. Overheating will not only affect the normal operation of the power distribution cabinet, but also damage the components inside the power distribution cabinet. Therefore, many power distribution cabinets are equipped with circulating cooling water for cooling. However, since the cooling water is recycled, the temperature of the cooling water will rise after multiple coolings, thereby reducing the cooling effect. In view of the above defects, this embodiment realizes the cooling operation of the power distribution cabinet body 1 through the setting of the cooling component 2, and achieves the effect of suppressing the temperature rise of the cooling water through the cooperation of components such as the heat dissipation fan 25 and the air outlet 26. The detailed implementation method is as follows:

[0025] The cooling component 2 includes a water storage chamber 1 21 and a water storage chamber 2 24 which are opened at the lower and upper parts of the power distribution cabinet body 1. A cooling chamber 22 is provided inside the power distribution cabinet body 1 and between the water storage chamber 1 21 and the water storage chamber 2 24. The cooling chamber 22 is communicated with the water storage chamber 1 21. A water cooling component 23 for cooling is provided inside the cooling chamber 22. A heat dissipation fan 25 is provided on the inner wall of the cooling chamber 22. An air outlet 26 for air circulation is provided on one side of the water storage chamber 1 21. In this embodiment, cooling water is provided in the water storage chamber 1 21. When cooling, the cooling water can be circulated in the cooling chamber 22 through the operation of the water cooling component 23, thereby utilizing The physical law of heat transfer displaces the heat in the distribution cabinet body 1 into the cooling water, thereby realizing the cooling operation of the distribution cabinet body 1. At the same time, when cooling, the heat dissipation fan 25 can be started synchronously to introduce the outside air into the cooling chamber 22, and finally flow out from the air outlet 26. Air will generate airflow during the flow process. When the airflow moves on the water storage chamber 21, it will entrain the heat in the water storage chamber 21, so as to achieve the effect of taking it out of the distribution cabinet body 1, thereby realizing the function of suppressing the temperature rise of the cooling water, expanding the temperature difference between the distribution cabinet body 1 and the cooling water, increasing the efficiency of heat transfer, and improving the cooling effect of the cooling component 2.

[0026] The water cooling assembly 23 includes a submersible pump 231 installed in the water storage chamber 1 21. The water outlet of the submersible pump 231 is provided with a water inlet pipe 232 connected to the water storage chamber 24. A cooling pipe 233 is provided inside the cooling chamber 22, and one end of the cooling pipe 233 is connected to the water storage chamber 1 21, and the other end is connected to the water storage chamber 24. When cooling, the cooling water can be lifted from the water storage chamber 1 21 to the water storage chamber 24 by the submersible pump 231 in cooperation with the water inlet pipe 232. Since the cooling pipe 233 is connected to the water storage chamber 24, the water storage chamber 24 is cooled. The cooling water in the second chamber 24 will flow along the cooling pipe 233 under the action of gravity, and the heat of the distribution cabinet body 1 will be replaced by the fitting of the cooling pipe 233 and the inner wall of the cooling chamber 22, and the cooling water will eventually return to the water storage chamber 1 21 to achieve circulating cooling. At the same time, because the cooling water is stored in the water storage chamber 1 21 for most of the time, and the water storage chamber 1 21 is located at the bottom of the distribution cabinet body 1, even if the cabinet corrodes and leaks, it will not affect the circuit, and the safety of the distribution cabinet body 1 is guaranteed.

[0027] The cooling pipe 233 is S-shaped. The special structure of the cooling pipe 233 increases the time for the cooling water to flow in the cooling pipe 233 , increases the time for the cooling water to replace heat, and improves the cooling effect of the water cooling component 23 .

[0028] A water supply pipe 28 connected to the water storage chamber 21 is provided on one side of the distribution cabinet body 1. The lower part of the water supply pipe 28 is connected to a liquid level pipe 29 connected to the water storage chamber 21. A baffle 210 for closing the water supply pipe 28 is slidably installed in the liquid level pipe 29, and a float chamber 211 is opened inside the baffle 210. In this embodiment, the setting of the liquid level pipe 29 intuitively displays the cooling water level in the water storage chamber 21, which is convenient for the staff to replenish water through the water supply pipe 28 in time. In addition, due to the setting of the float chamber 211, the buoyancy of the baffle 210 in the water is greater than its own gravity. Therefore, when there is sufficient cooling water in the water storage chamber 21, the baffle 210 will automatically float up to close the water supply pipe 28, thereby preventing external impurities from entering the water storage chamber 21, polluting the cooling water, and affecting heat dissipation. When the cooling water level drops, the baffle 210 will also drop synchronously, which is convenient for the staff to replenish water through the water supply pipe 28.

[0029] Embodiment 2

[0030] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that the circulating cooling water inside the existing automatic cooling distribution cabinet will cause the water temperature to rise after multiple coolings, thereby affecting the cooling effect. However, when the temperature inside the distribution cabinet body 1 is not high and the cooling component 2 is not running, the heat dissipation fan 25 will not run either, so there is no airflow flowing out from the air outlet 26. At this time, external dust can easily enter the water storage chamber 21 to contaminate the cooling water and reduce its cooling effect.

[0031] Reference Figure 1-Figure 4 The cross section of the air outlet 26 is a factory type, and a filter screen 27 is fixedly installed at the lower part of the air outlet 26. Because these pollutants will increase the resistance of the cooling water and increase the water temperature, thereby reducing the cooling effect, this embodiment achieves the filtration of external dust through the setting of the filter screen 27, avoiding the pollution of the cooling water. In addition, the setting of the factory-type cross section of the air outlet 26 can further limit the external impurities from breaking through their own gravity and entering the water storage chamber 21, thereby ensuring the cooling effect of the equipment.

[0032] A battery electrically connected to the submersible pump 231 is provided in the distribution cabinet body 1. A photovoltaic panel 3 for photoelectric conversion is provided on the upper part of the distribution cabinet body 1, and the photovoltaic panel 3 is electrically connected to the battery. The setting of the photovoltaic panel 3 can convert light energy into electrical energy and store it when the distribution cabinet body 1 is used outdoors, which is convenient for the subsequent use of the submersible pump 231, thereby achieving the effect of saving resources.
