However, this kind of way has obvious limitations: first, the dust screen is easy to be blocked by dust, willow catkins and other sundries, and needs frequent maintenance and seriously affects the heat dissipation efficiency; second, in order to ensure the protection level (such as IP54), the cabinet body often needs to adopt higher sealing design, which is contradictory to the ventilation demand required by heat dissipation; third, under the condition of high temperature or direct sunlight in summer, the ambient temperature is already very high, and the efficiency of air cooling is greatly reduced, resulting in heat accumulation in the cabinet, which seriously affects the reliability and service life of the internal components.

[0004] In addition, although some schemes try to use water cooling for heat dissipation, they usually need to rely on external water source or complex closed-loop cooling system, which has complex structure, high cost, and does not fully consider the outdoor rainwater collection and utilization, waterproof sealing and maintenance convenience of the system itself. How to fully utilize the natural environmental conditions to design an outdoor switch cabinet with reasonable structure, efficient heat dissipation, reliable waterproof and convenient maintenance is still a technical problem to be solved in the field.

DETAILED DESCRIPTION

[0035] The application will be further described below in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0037] As shown in Figures 1-7 , the utility model provides a kind of outdoor waterproof heat dissipation type switch cabinet, including:

[0038] Waterproof tank 8 is used to accommodate electrical equipment;

[0039] Water-cooled radiator shell 5 is installed on the outer wall of the waterproof tank 8, and the circulating water path 16 is formed in the water-cooled radiator shell 5;

[0040] Refrigeration fin 17 is installed in the water-cooled radiator shell 5 and contacts the circulating water path 16;

[0041] Heat dissipation water collecting tank 1 is installed on the outer side of the waterproof tank 8, and is in fluid communication with the circulating water path 16 through the circulating water pumping pipe 2 and the circulating water outlet pipe 3;

[0042] Circulating water pumping assembly is installed between the heat dissipation water collecting tank 1 and the circulating water path 16, for driving water to circulate between the heat dissipation water collecting tank 1 and the circulating water path 16.

[0043] Specifically, refer to Figure 1 , Figure 2 and Figure 3The outdoor waterproof heat dissipation switch cabinet in the embodiment comprises a waterproof box 8, which is composed of a closed cavity by welding or assembling metal plates, and is used for accommodating electrical equipment such as circuit breakers, contactors and control modules. The inner and outer surfaces thereof are subjected to corrosion protection treatment to improve the weather resistance in outdoor environment. A water-cooled radiator shell 5 is fixedly installed on the back outer wall of the waterproof box 8 by bolts. The water-cooled radiator shell 5 is usually made of aluminum alloy or other high-thermal-conductivity metal materials, and a hollow circulating water channel 16 is formed in the inner cavity thereof by machining or casting.

[0044] Referring to Figure 4 , Figure 5 and Figure 6 , the circulating water channel 16 is a continuous channel, and the cross-sectional shape thereof can be circular or rectangular. A refrigeration fin 17 is a semiconductor refrigeration device, which is installed on the bottom of the inner cavity of the water-cooled radiator shell 5 by means of thermal conductive silicone grease and mechanical buckle or screw fastening, and makes the cold end face thereof in close contact with the outer wall of the circulating water channel 16 to ensure efficient heat conduction.

[0045] The heat dissipation water collecting tank 1 is usually made of stainless steel or engineering plastic, and is installed on the right outer wall of the waterproof box 8 by means of support and bolt connection, and is located lower than the water-cooled radiator shell 5. The heat dissipation water collecting tank 1 is in fluid communication with the circulating water channel 16 through a circulating water suction pipe 2 and a circulating water outlet pipe 3. A circulating water suction assembly is installed between the heat dissipation water collecting tank 1 and the circulating water channel 16, and is used for driving water to circulate between the heat dissipation water collecting tank 1 and the circulating water channel 16.

[0046] Referring to Figure 4 and Figure 5 , the circulating water suction assembly comprises a water suction pump 4 installed on the bottom of the heat dissipation water collecting tank 1. The water suction pump 4 is connected with the circulating water channel 16 through the circulating water suction pipe 2. The water suction pump 4 is a small submersible pump, and the pump body thereof is fixedly installed on the inner bottom surface of the heat dissipation water collecting tank 1 by means of support. The water suction pump 4 directly draws water in the tank through the water inlet. One end of the circulating water suction pipe 2 is connected with the water outlet of the water suction pump 4 through a flange or quick connector, and the other end thereof is connected with the water inlet of the circulating water channel 16 through a corresponding connector, so that the water suction pump 4 can pump the cooling water in the heat dissipation water collecting tank 1 into the circulating water channel 16. The water outlet of the circulating water channel 16 is connected with the heat dissipation water collecting tank 1 through the circulating water outlet pipe 3. Specifically, one end of the circulating water outlet pipe 3 is connected with the water outlet of the circulating water channel 16 through a flange or quick connector, and the other end thereof extends to above the opening of the heat dissipation water collecting tank 1, so that the water flow after heat exchange can return to the heat dissipation water collecting tank 1 by gravity to complete a complete cooling cycle.

[0047] The circulating water pumping pipe 2 and the circulating water outlet pipe 3 can adopt a sectional structure, are connected through a quick connector, and can be flexibly adjusted in length according to actual installation distance on site, so as to meet layout requirements of different application scenarios.

[0048] Referring to Figure 5 , the circulating water pumping assembly further comprises a motor 7, which is installed on the outer wall of the waterproof box 8 and connected with the water pumping pump 4.

[0049] The motor 7 is installed in a waterproof motor box on the outer wall of the back of the waterproof box 8. The output shaft of the motor 7 is connected with the impeller shaft of the water pumping pump 4 through a sealed coupling and penetrates the wall of the heat dissipation water collecting box 1, so as to provide power for the operation of the water pumping pump 4. The above-mentioned transmission structure and sealing structure are prior art, and will not be described here. Any structure capable of achieving the transmission of the motor 7 and the water pumping pump 4 is within the protection scope of the utility model.

[0050] Referring to Figure 1 and Figure 4 , as a further explanation of the utility model, the filter mechanism further comprises an impurity filter screen 9 arranged on the top of the heat dissipation water collecting box 1.

[0051] In this embodiment, the impurity filter screen 9 preferably adopts a stainless steel or corrosion-resistant metal wire mesh. The mesh aperture is selected according to the size of the impurity particles to be filtered, and is usually between 0.5 mm and 2 mm, so as to effectively intercept leaves, insects, large particle dust and other impurities. A rectangular rain inlet opening is formed on the top of the heat dissipation water collecting box 1. The periphery of the opening is inwardly or outwardly flanged to form a clamping groove or mounting edge for mounting and positioning. The shape and size of the impurity filter screen 9 are matched with the rain inlet opening. The edge of the impurity filter screen 9 is fixed to the clamping groove or mounting edge by means of a pressing strip, a screw or direct clamping, so as to ensure firm mounting and good sealing at the joint with the box body, and prevent unfiltered rainwater from seeping in. The impurity filter screen 9 is installed in a horizontal or slightly inclined state to the outside of the box body, so as to facilitate the natural sliding of impurities and facilitate daily cleaning and maintenance. Natural rainwater or externally injected water must first pass through the impurity filter screen 9 before entering the water storage cavity of the heat dissipation water collecting box 1, so as to effectively prevent impurities from entering the cooling circulating system, avoid blocking the circulating water path 16, the water pumping pump 4 or affecting the heat exchange efficiency of the refrigeration fin 17, and ensure long-term reliable operation of the entire water-cooled heat dissipation system.

[0052] Referring to Figure 7 , as a further explanation of the utility model, the filter mechanism further comprises a water inlet 10 arranged on the side of the heat dissipation water collecting box 1, a water inlet filter screen 11 mounted on the inner side of the water inlet 10, and a water inlet plug 12 detachably connected with the water inlet 10.

[0053] Specifically, a circular water inlet 10 is formed at the bottom of the right outer wall or the bottom of the side wall of the heat dissipation water collecting tank 1, which is preferably a metal pipe joint with internal or external threads and is fixedly connected to the tank wall by welding or riveting. A water inlet filter screen 11 is installed on the inner side of the water inlet 10, i.e., the side inside the heat dissipation water collecting tank 1. The water inlet filter screen 11 is usually a cup-shaped or disc-shaped mesh structure made of stainless steel or engineering plastic. Its edge is fixed to the inner end of the water inlet 10 or the inner wall of the tank near the water inlet 10 by interference fit, threaded connection or buckle connection, and its mesh size is smaller than that of the top impurity filter screen 9, which is used for secondary fine filtration of the standby water source injected from the water inlet and further blocks small particles. The water inlet plug 12 is usually made of rubber, silicone or plastic, and its end is provided with internal threads matching the external threads of the water inlet 10, or it is provided with external threads matching the internal threads of the water inlet 10, or it is a tapered plug made of soft material and sealed by interference fit. By screwing or pressing the water inlet plug 12, it can be reliably sealed and connected with the water inlet 10 to prevent dust from entering and water from leaking. When there is insufficient natural rainwater or emergency cooling water needs to be supplemented, the water inlet plug 12 can be opened, and clean water can be injected into the heat dissipation water collecting tank 1 through the water inlet 10. The water flow first passes through the water inlet filter screen 11 before entering the tank, thereby effectively ensuring the cleanliness of the cooling water and maintaining the stability and reliability of the entire circulating heat dissipation system.

[0054] Referring to Figure 3 , Figure 4 and Figure 7 , as a further explanation of the utility model, it further includes a waterproof mechanism, which includes a waterproof cover 13 covering the outside of the water-cooled radiator shell 5.

[0055] Specifically, the waterproof cover 13 is formed by stamping a metal plate or injection molding an engineering plastic, and has a cover-shaped structure with a tilted or arc-shaped top to facilitate rainwater sliding off. The waterproof cover 13 is fixedly installed on the back outer wall of the waterproof tank 8 by mounting lugs provided on its edge using bolts or screws, and is installed above and around the water-cooled radiator shell 5, the circulating waterway 16 and part of the exposed pipeline, thereby forming a complete protection space in which the above-mentioned heat dissipation components are covered.

[0056] The waterproof cover 13 is designed to ensure that there is sufficient air flow gap between it and the protected heat dissipation components, and a ventilation louver or mesh hole can be provided below the side to balance heat dissipation and dust prevention. The main function of the waterproof cover 13 is to block the direct impact and splashing of rain, hail and the like from the top and side directions, and also effectively prevent leaves, large debris and the like from falling and accumulating on the surface of the heat dissipation components, avoiding the performance degradation, corrosion or short circuit risk of the water-cooled heat dissipation system caused by external environmental factors, and significantly improving the reliability and safety of the equipment in outdoor harsh environments.

[0057] Referring to Figure 4 and Figure 5 , as a further explanation of the utility model, the waterproof mechanism further comprises a waterproof heat dissipation hole 14 arranged on the side wall of the waterproof box 8.

[0058] Specifically, the waterproof heat dissipation hole 14 is a plurality of through hole arrays arranged side by side on the upper half of the left and right side walls of the waterproof box 8. Each through hole is preferably a louvered hole structure inclined outward and downward, that is, a series of continuous, outward protruding louver blades are formed on the wall panel of the box by stamping, and the inclined through holes are formed between adjacent blades. The inclination angle of the louver blade is between 30° and 60°, and the protruding direction is towards the outside of the box, so that when viewed from the outside, the entrance direction of the through hole is inclined downward. This structure allows external air to smoothly enter the box through the inclined channel, forming a convection to carry away the heat generated by the electrical elements, achieving auxiliary heat dissipation. At the same time, since the hole is inclined downward and the external louver blade blocks it, whether it is vertically falling rain or obliquely splashing water droplets, it is effectively blocked and diverted by the blade to the outer wall of the box, so it cannot directly enter the box interior, ensuring ventilation and heat dissipation while achieving reliable waterproof protection. The waterproof heat dissipation hole 14 is simple in structure and easy to manufacture, and together with the water-cooled heat dissipation system, it constitutes a high-efficiency multi-level heat dissipation and protection system of the switchgear.

[0059] In another embodiment, the waterproof heat dissipation hole 14 is opened in the upper half of the left and / or right side wall of the waterproof box 8, which is not a simple straight-through circular hole, but a multi-bend air duct structure in the form of a labyrinth or a louver. The air duct structure is composed of a plurality of water-blocking eaves plates recessed inwardly formed by stamping the outer wall of the box and the corresponding air guide channels on the inner wall of the box, so that the external air entering the inside of the box needs to change direction at least twice. The overall air inlet direction of the waterproof heat dissipation hole 14 is preferably designed to be downwardly inclined or in the form of an "S" shape, and the gap between the adjacent water-blocking eaves plates inside is kept at 0.5-2 mm to allow air flow. This structure can effectively allow the hot air generated by the electrical equipment in the waterproof box 8 to exchange with the external cold air by convection, achieving natural ventilation and heat dissipation; at the same time, whether it is vertically falling rain or splashing water with a certain angle, after entering the zigzag labyrinth air duct, its kinetic energy will be blocked and attenuated many times, and finally be intercepted by the water-blocking eaves plate and drained along the outer wall of the box, so as to prevent direct entry into the inside of the box, ensuring high-level waterproof performance, usually reaching IPX5 and above protection level.

[0060] Referring to Figure 7 , as a further explanation of the utility model, the outer surface of the water-cooled radiator shell 5 is coated with a heat dissipation silicone grease 6.

[0061] Specifically, the heat dissipation silicone grease 6 is a high-thermal-conductivity insulating silicone grease material, and the thermal conductivity coefficient thereof is preferably not less than 3.0 W / m·K. During assembly, the heat dissipation silicone grease 6 is first uniformly coated on the entire installation contact surface of the water-cooled radiator shell 5, and the coating thickness is controlled to be between 0.1 mm and 0.3 mm, so as to ensure that the micro gaps of the contact surface can be fully filled, and the thermal resistance will not be significantly increased due to excessive thickness. Subsequently, the water-cooled radiator shell 5 coated with the heat dissipation silicone grease 6 is installed on the designated position of the back outer wall of the waterproof box 8 by bolt fastening. The heat dissipation silicone grease 6 plays a key role here, which can effectively fill the small gaps between the metal surface of the water-cooled radiator shell 5 and the metal box wall of the waterproof box 8 due to surface unevenness, and exclude the air therefrom, so as to significantly reduce the contact thermal resistance between the two contact interfaces, and establish a high-efficiency heat conduction path from the heating elements inside the waterproof box 8 to the outside water-cooled radiator shell 5. This enables the heat generated by the electrical equipment during operation to be more quickly and efficiently conducted to the water-cooled radiator shell 5 through the box wall, and then taken away by the circulating cooling water inside, greatly improving the overall heat dissipation efficiency and ensuring the stable control of the temperature of the electrical equipment in the cabinet.

[0062] Referring to Figure 2 , as a further explanation of the utility model, the front of the waterproof box 8 is provided with a waterproof opening and closing cover 15, and the waterproof opening and closing cover 15 is connected with the waterproof box 8 through a hinge.

[0063] Specifically, the waterproof opening and closing cover 15 is made of metal plate material, the size of which matches the opening size of the front face of the waterproof box 8, and is used to close or open the equipment cabin inside the waterproof box 8. On one side edge of the opening of the front face of the waterproof box 8, preferably the right side edge, at least two hinge base parts are installed by welding or bolt fixing; correspondingly, on the inner side of the waterproof opening and closing cover 15 at the corresponding position, rotating leaf parts matched with the hinge base are installed. The rotating leaf is connected with the base through a hinge shaft, so that the waterproof opening and closing cover 15 can be rotated and opened and closed around the hinge shaft. In order to further ensure the sealing, a continuous sealing rubber strip, for example, rubber or silicone material, is embedded on the frame around the waterproof opening and closing cover 15 matched with the inner wall of the opening of the front face of the waterproof box 8. When the waterproof opening and closing cover 15 is closed, it is pressed against the front face of the box through the locking device arranged on the other side of the opening, so that the sealing rubber strip is elastically deformed, thereby forming a reliable sealing barrier between the box and the door, effectively preventing the intrusion of rain and dust. The design not only facilitates the operation personnel to open the door to install, overhaul and maintain the internal electrical equipment, but also ensures that the cabinet has a very high protection level when it is closed, meeting the harsh requirements of long-term outdoor use.

[0064] The locking device is a prior art, and the specific structure is not described here.

[0065] Referring to Figure 1 As a further explanation of the utility model, the heat dissipation and water collecting box 1 is detachably installed on the side face of the waterproof box 8.

[0066] Specifically, at least two L-shaped or U-shaped mounting brackets are pre-welded or fixed by bolts on the right side outer wall of the waterproof box 8, and bolt holes are arranged in the mounting brackets. Correspondingly, connecting ear plates matched with the positions of the mounting brackets and the bolt holes or through holes are arranged on the outer wall of the box body of the heat dissipation and water collecting box 1 close to the waterproof box 8. By passing the bolts through the bolt holes of the mounting brackets and the ear plate through holes of the heat dissipation and water collecting box 1 and fastening with nuts, the heat dissipation and water collecting box 1 can be firmly and detachably installed on the side face of the waterproof box 8. The detachable connection mode facilitates the user to take out the heat dissipation and water collecting box 1 from the waterproof box 8 as a whole, so as to facilitate the user to thoroughly clean the inside of the water collecting box, remove the deposited impurities, replace or clean the impurity filter screen 9 located at the top of the water collecting box and the water inlet filter screen 11 located inside the water inlet 10, and also facilitate the maintenance or overhaul of the water pump 4 and other operations located inside, thereby greatly improving the maintainability of the equipment.

[0067] The technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
