Description

Technical Field

[0001] The present invention relates to the technical field of power supply cabinets, and in particular to a high-efficiency heat dissipation mechanism for a high-frequency power supply cabinet. Background Art

[0002] As a core component in the power electronics field, high-frequency switching power supply cabinets utilize advanced high-frequency switching technology to efficiently convert input AC power into stable DC output. Integrated with power conversion modules, control circuits, and filtering circuits, they offer numerous significant advantages: high conversion efficiency effectively reduces energy loss; high output accuracy provides precise and stable power to various loads; and a compact size and lightweight design conserve installation space. In communication base stations, they ensure the reliable operation of communications equipment; in data centers, they provide continuous and stable power support for servers and other equipment; and in industrial automation, they meet the power needs of various production equipment.

[0003] However, existing high-frequency switching power supply cabinets generate a large amount of heat during operation, especially during peak periods of high summer temperatures and electricity consumption. When the power supply cabinet is operating at high load, the temperature inside the cabinet can rise significantly. While some existing fire extinguishing devices installed in the cabinet can effectively prevent fires, they occupy a large amount of cabinet space, are costly, and fail to address the high temperature problem. Furthermore, existing power supply cabinets are typically divided into multiple zones, each equipped with modules. However, the gaps between the modules and the cabinet walls are narrow, hindering air circulation and easily causing localized overheating. Furthermore, the poor airflow between the zones slows the dissipation of localized heat, resulting in limited heat dissipation efficiency. Especially in hot weather, the fan draws hot air into the cabinet, which does not effectively dissipate the heat. Therefore, a high-efficiency heat dissipation mechanism for high-frequency power supply cabinets is proposed to address the above issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an efficient heat dissipation mechanism for a high-frequency power cabinet to solve the problems of poor heat dissipation effect of existing power cabinets in hot weather and poor air circulation between modules, which ultimately leads to limited heat dissipation efficiency.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A high-efficiency heat dissipation mechanism for a high-frequency power supply cabinet includes a main cabinet and a cabinet door. The main cabinet is provided with a mounting frame consisting of multiple support tubes and multiple mounting tubes. Multiple modules are installed on the mounting frame, and the mounting tubes are located between the module gaps. The main cabinet is provided with an inlet and outlet fan assembly. The outlet fan assembly includes a cooler for cooling the air entering the main cabinet and sucking out the hot air from the main cabinet.

[0007] Optionally, the air inlet and outlet fan assembly includes a sub-cabinet fixed to the top of the main cabinet, and a cabinet cover installed on the top of the sub-cabinet, a second air outlet fan and a first air outlet fan are installed on the side walls of the main cabinet, and an air intake fan is installed between the sub-cabinet and the main cabinet; a plurality of thermal insulation filling layers are fixedly connected in the sub-cabinet, a plurality of mounting grooves are formed between the plurality of thermal insulation filling layers, air intake pipes are installed in the plurality of mounting grooves, the outer ends of the plurality of air intake pipes all pass through the sub-cabinet and extend outward, the refrigerator is installed in the mounting groove, and a contact plate that contacts the refrigerator is fixedly connected to the top of the air intake pipe; a mounting ring is fixedly connected between the sub-cabinet and the main cabinet, a diverter box is fixedly connected to the bottom end of the mounting ring, the air intake fan is installed at the bottom end of the diverter box, and a plurality of flow holes are opened on the side walls of the diverter box, and the diverter box and the air intake fan are fixedly connected. A gap is formed between them; the inner ends of multiple air inlet pipes are fixedly connected to extension pipes located in the diversion box, wherein the cooler is a prior art, such as a semiconductor refrigeration plate, and an inlet and outlet fan assembly is set. When in use, the intake fan draws external air into the main cabinet through several air inlet pipes, and the second air outlet fan discharges the air in the main cabinet to the outside, thereby achieving the purpose of circulating exhaust and heat dissipation; by setting a cooler that cooperates with the air outlet fan assembly, first the cooler is installed in the installation groove and contacts with the contact plate on the air inlet pipe, and an insulation filling layer is provided between the multiple air inlet pipes. When in use, the cooler works to cool the air inlet pipe in the installation groove gradually.

When the second water diversion pipe and the thermal bulb above are full, the condensed water flows back to the first water diversion pipe through the area below the dividing plate, and the condensed water flows into the second water diversion pipe below through the jack through the first water diversion pipe below. Since the diameter of the jack is larger than the diameter of the first water diversion pipe, when there is condensed water on the outer wall of the first water diversion pipe, the condensed water can flow along the outer wall of the first water diversion pipe into the second water diversion pipe below and the thermal bulb for storage.

[0010] Optionally, there are at least two groups of support tubes and mounting tubes, and the two groups of mounting tubes are located between the two groups of support tubes; a plurality of mounting holes are provided on the outer wall of the mounting tube, and the module is fixed in the mounting hole by fasteners, and the plurality of mounting holes connect the mounting tube and the main cabinet; by providing mounting holes on the mounting tube, on the one hand, the mounting holes can be used as fixing holes, which can cooperate with external fasteners to fix structures such as switch modules on the mounting tube; on the other hand, the mounting holes can be used as water flow holes, so that when the thermal ball explodes, the condensed water can flow out quickly to extinguish the fire; in addition, the mounting holes can be used as heat dissipation holes, and the mounting tube is located between the gaps of multiple modules.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above scheme, by setting up an inlet and outlet fan assembly, the air intake fan draws external air into the main cabinet through several air intake pipes, and the second air outlet fan discharges the air in the main cabinet to the outside, thereby achieving the purpose of circulating exhaust and heat dissipation. By setting up a cooler that cooperates with the air outlet fan assembly, the external air passing through the air intake pipe is cooled. The cooled air enters the main cabinet, which can greatly improve the heat dissipation capacity and is suitable for working in hot environments.

[0015] By setting a diverter box under the air inlet pipe, condensed water and air can be separated. Therefore, during operation, cool air is transported to the main cabinet through the circulation holes and gaps on the side walls of the diverter box, while the diverter box collects condensed water to prevent it from affecting the safe operation of the main cabinet; by setting a first water inlet pipe and a second water inlet pipe, the condensed water collected in the diverter box can flow into the thermal bulb along the first water inlet pipe and the second water inlet pipe for storage.

The second exhaust fan is connected to the support tube and the mounting tube through the connecting tube, so that the heat in the gaps between the modules is discharged outward through the mounting hole, thereby solving the problems of uneven heat dissipation effect and difficulty in discharging local heat in traditional cabinets. At the same time, the structure is simple, the cost is low, and it is conducive to mass production. BRIEF DESCRIPTION OF THE DRAWINGS

It is also noted that, for the sake of completeness, the following embodiments are optimal and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0035] It should be noted that references in the specification to "one embodiment," "an embodiment," "an exemplary embodiment," "some embodiments," etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not every embodiment necessarily includes such specific features, structures, or characteristics. In addition, when specific features, structures, or characteristics are described in conjunction with an embodiment, it is within the knowledge of persons skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0036] like Figures 1 to 13 As shown, an embodiment of the present invention provides an efficient heat dissipation mechanism for a high-frequency power supply cabinet, including a main cabinet 1 and a cabinet door 2. The main cabinet 1 is provided with a mounting frame consisting of multiple support tubes 16 and multiple mounting tubes 24. Multiple modules are installed on the mounting frame. The modules are power switch modules installed in the high-frequency power supply cabinet, etc., and the mounting tubes 24 are located between the module gaps; the main cabinet 1 is provided with an inlet and outlet fan assembly, and the outlet fan assembly includes a cooler 10, which is used to cool the air entering the main cabinet 1 and suck out the hot air from the main cabinet 1.

[0037] like Figure 2 、 Figures 11 to 13As shown, the air inlet and outlet fan assembly includes a sub-cabinet 4 fixed to the top of the main cabinet 1, and a cabinet cover 19 installed at the top of the sub-cabinet 4, a second air outlet fan 21 and a first air outlet fan 3 are installed on the side walls of the main cabinet 1, and an air intake fan 12 is installed between the sub-cabinet 4 and the main cabinet 1; a plurality of thermal insulation filling layers 6 are fixedly connected in the sub-cabinet 4, a plurality of mounting grooves 7 are formed between the plurality of thermal insulation filling layers 6, and air intake pipes 8 are installed in the plurality of mounting grooves 7, and the outer ends of the plurality of air intake pipes 8 all pass through the sub-cabinet 4 and extend outward, the refrigerator 10 is installed in the mounting groove 7, and a contact plate 9 in contact with the refrigerator 10 is fixedly connected to the top of the air intake pipe 8; a mounting ring 13 is fixedly connected between the sub-cabinet 4 and the main cabinet 1, a diverter box 11 is fixedly connected to the bottom end of the mounting ring 13, the air intake fan 12 is installed at the bottom end of the diverter box 11, and a plurality of flow holes 14 are opened on the side walls of the diverter box 11, and a gap 15 is formed between the diverter box 11 and the air intake fan 12; a plurality of air intake pipes 8 The inner ends are fixedly connected to extension pipes 18 located in the diversion box 11, wherein the cooler 10 is a prior art, such as a semiconductor refrigeration plate, by setting an inlet and outlet fan assembly. When in use, the intake fan 12 draws external air into the main cabinet 1 through several intake pipes 8, and the second outlet fan 21 discharges the air in the main cabinet 1 to the outside, thereby achieving the purpose of circulating exhaust and heat dissipation; by setting a cooler 10 that cooperates with the outlet fan assembly, first, the cooler 10 is installed in the installation groove 7 and contacts the contact plate 9 on the intake pipe 8, and an insulation filling layer 6 is provided between the multiple intake pipes 8. When in use, the cooler 10 works to cool the intake pipe 8 in the installation groove 7 and gradually cools down the intake pipe 8. Since the external air will first pass through the intake pipe 8 when entering the main cabinet 1 through the intake pipe 8, the external air passing through the intake pipe 8 is cooled. The cooled air enters the main cabinet 1, which can greatly improve the heat dissipation capacity, making it suitable for working in a hot environment.

[0038] In addition, by arranging a diverter box 11 below the air intake pipe 8, as the air intake pipe 8 works for a long time to cool the external hot air, condensation is likely to occur on its pipe wall. The condensation can enter the bottom of the diverter box 11 through the air intake pipe 8 and the extension pipe 18. When the air intake fan 12 is working, the cool air is transported into the main cabinet 1 through the flow holes 14 and the gaps 15 on the side walls of the diverter box 11, thereby processing the air without affecting the air delivery.

[0039] It should be noted that the air intake pipe 8 can be replaced with a curved structure to increase the contact area between the external air and the air intake pipe 8 and extend the contact time of the external air, thereby further cooling the external air.

[0040] like Figure 6 、 Figure 7 As shown, the top of the support tube 16 is fixed to the diversion box 11 , and one end of the support tube 16 away from the diversion box 11 is fixedly connected to a connecting tube 23 , which is connected to a closing cover 22 fixed on the second exhaust fan 21 .

[0041] like Figures 6 to 10 As shown, the side wall of the diversion box 11 is fixedly connected to a first water diversion pipe 17, and the first water diversion pipe 17 is fixedly connected to a second water diversion pipe 26 with the same number as the mounting pipe 24, and a separator 5 is fixedly connected between the second water diversion pipe 26 and the first water diversion pipe 17. The second water diversion pipe 26 is an inclined structure, and a detachable thermal ball 27 is installed between the second water diversion pipe 26 of the inclined structure; wherein, the top of the second water diversion pipe 26 located at the bottom is provided with a socket 28, and the bottom end of the first water diversion pipe 17 is inserted into the socket 28, and the diameter of the socket 28 is larger than the diameter of the first water diversion pipe 17; by arranging the first water diversion pipe 17 in the supporting pipe 16 and the second water diversion pipe 26 in the mounting pipe 24, since the top of the first water diversion pipe 17 is connected to the bottom of the diversion box 11, the condensed water collected in the diversion box 11 can flow into the thermal ball along the first water diversion pipe 17 and the second water diversion pipe 26. 27, and the condensed water in the first water diversion pipe 17 encounters the obstruction of the partition 5 when flowing downward, so that it flows into the second water diversion pipe 26. When the second water diversion pipe 26 and the thermal ball 27 above are full, the condensed water flows back to the first water diversion pipe 17 through the area below the partition 5, and the condensed water flows into the second water diversion pipe 26 below through the first water diversion pipe 17 below through the plug hole 28. Since the diameter of the plug hole 28 is larger than the diameter of the first water diversion pipe 17, when there is condensed water on the outer wall of the first water diversion pipe 17, the condensed water can flow along the outer wall of the first water diversion pipe 17 into the second water diversion pipe 26 below and the thermal ball 27 for storage. The advantage of this arrangement is that the generated condensed water can be stored. When the thermal ball 27 is subjected to the high temperature of the open flame, the thermal ball 27 will burst and explode, and the water inside it will flow into the mounting pipe 24 and out through the mounting hole 25 thereon, thereby performing fire extinguishing.

[0042] It should be noted that the thermosensitive ball 27 is made of existing technical materials and will not be described in detail here.

[0043] like Figure 3 、 Figures 6 to 8As shown, there are at least two groups of support tubes 16 and mounting tubes 24, and the two groups of mounting tubes 24 are located between the two groups of support tubes 16; a plurality of mounting holes 25 are provided on the outer wall of the mounting tube 24, and the modules are fixed in the mounting holes 25 by fasteners, and the plurality of mounting holes 25 enable the mounting tube 24 and the main cabinet 1 to be in a connected state; by providing the mounting holes 25 on the mounting tube 24, on the one hand, the mounting holes 25 can be used as fixing holes, which can cooperate with external fasteners to fix structures such as switch modules on the mounting tube 24; on the other hand, the mounting holes 25 can be used as water flow holes, so that when the thermal ball 27 explodes, the condensed water can flow out quickly to extinguish the fire; in addition, the mounting holes 25 can be used as heat dissipation holes, and the mounting tube 24 is located between the gaps of multiple modules. The second exhaust fan 21 is connected to the support tube 16 and the mounting tube 24 through the connecting tube 23, so that the heat in the gaps between the modules is discharged outward through the mounting holes 25, thereby solving the problems of uneven heat dissipation effect and difficulty in discharging local heat in traditional cabinets.

[0044] like Figure 12 As shown, the outer ends of the multiple air inlet pipes 8 are all installed with dustproof nets 20, which are used to reduce external dust from entering the air inlet pipes 8. The air inlet pipes 8 are located at the top of the main cabinet 1 to prevent small animals from entering.

[0045] like Figure 12 As shown, the air intake pipe 8 and the extension pipe 18 are an integral structure, and the connection between the air intake pipe 8 and the extension pipe 18 is in a bent state. The multiple air intake pipes 8 are arranged in a ring with the diverter box 11 as the center.

[0046] like Figure 6 、 Figure 8 As shown, the end of the support tube 16 away from the diversion box 11 is tilted downward, and the mounting tube 24 and the support tube 16 are both made of metal with good thermal conductivity, which improves the heating of the thermistor ball 27 in the mounting tube 24 and reduces the heating delay and loss, thereby facilitating the explosion of the thermistor ball 27.

[0047] The working principle of the technical solution provided by the present invention is as follows: when in use, the air intake fan 12 draws external air into the main cabinet 1 through a plurality of air intake pipes 8, and the second air outlet fan 21 discharges the air in the main cabinet 1 to the outside. When the refrigerator 10 is working for cooling, the air intake pipe 8 in the installation slot 7 is gradually cooled down. Since the external air passes through the air intake pipe 8 before entering the main cabinet 1 through the air intake pipe 8, the external air passing through the air intake pipe 8 is cooled down. The cooled air enters the main cabinet 1, which can greatly improve the heat dissipation capacity.

[0048] The condensed water generated by long-term work enters the bottom of the diversion box 11 through the air inlet pipe 8 and the extension pipe 18, and the cool air is transported to the main cabinet 1 through the flow holes 14 and the gaps 15 on the side walls of the diversion box 11, while the condensed water flows along the first water inlet pipe 17 and the second water inlet pipe 26 into the thermal ball 27 for storage. When the thermal ball 27 is exposed to the high temperature of the open flame, the thermal ball 27 will burst and explode, and the water inside it will flow into the installation pipe 24 and out through the installation hole 25 on it, thereby extinguishing the fire in the area.

[0049] In addition, the structure of the present invention can be used in conjunction with the temperature control equipment of the prior art to achieve the purpose of automatically adjusting the wind speed and cooling intensity according to the preset temperature, which will not be described in detail here.

[0050] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
