[0001] This application relates to the field of power electronics technology, and more specifically, to a cabinet and a converter. Background Technology

[0002] Crowbar resistors are typically installed outside the converter cabinet. For outdoor applications, waterproofing is required to ensure their proper operation. However, current converters have structural limitations that prevent them from providing a suitable waterproofing solution for crowbar resistors located outside the cabinet. Therefore, how to achieve a waterproof arrangement of crowbar resistors outside the cabinet has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a cabinet for implementing a waterproof arrangement of the crowbar resistor outside the cabinet.

[0004] Another object of this application is to provide a converter including the aforementioned cabinet.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A server rack, comprising:

[0007] Cabinet;

[0008] A protective component is disposed outside the cabinet and connected to the cabinet. The protective component includes a first cover and a second cover. The first cover is disposed outside the second cover, and a waterproof cavity is formed between the first cover and the second cover. The inner cavity of the second cover serves as an installation cavity. The first cover includes a first heat dissipation area, and a first heat dissipation channel communicating with the outside and the waterproof cavity is formed on the first heat dissipation area. The second cover includes a second heat dissipation area, and a second heat dissipation channel communicating with the waterproof cavity and the installation cavity is formed on the second heat dissipation area.

[0009] Optionally, in the aforementioned cabinet, the first heat dissipation area and the second heat dissipation area are staggered along the extension direction of the first heat dissipation channel.

[0010] Optionally, in the aforementioned cabinet, along the extension direction of the first heat dissipation channel, the area on the second cover corresponding to the first heat dissipation area is a water-blocking area;

[0011] Along the height direction of the cabinet, the second heat dissipation area is positioned entirely above the water-blocking area.

[0012] Optionally, in the aforementioned cabinet, the first heat dissipation channel is arranged at a downward angle from inside the first enclosure to outside the first enclosure.

[0013] Optionally, in the aforementioned cabinet, the second heat dissipation channel is arranged at a downward angle from inside the second enclosure to outside the second enclosure.

[0014] Optionally, in the aforementioned cabinet, the protective components further include:

[0015] The tray is connected to the second cover and closes the opening of the second cover, and the tray has a drainage hole that connects the mounting cavity to the outside.

[0016] A first bracket is disposed between the tray and the cabinet, and a drainage gap is provided between the tray and the cabinet, wherein the drainage hole communicates with the drainage gap.

[0017] Optionally, in the aforementioned cabinet, the tray is provided with a second support for supporting electronic devices.

[0018] Optionally, in the aforementioned cabinet, the bottom of the waterproof cavity is connected to the drainage gap.

[0019] Optionally, in the above-mentioned cabinet, a waterproof terminal is provided between the cabinet body and the tray. The cabinet body has a first wiring through hole that connects the waterproof terminal to the inner cavity of the cabinet body, and the tray has a second wiring through hole that connects the waterproof terminal to the mounting cavity. The waterproof terminal, the first wiring through hole, and the second wiring through hole are all for cables to pass through.

[0020] Optionally, in the aforementioned cabinet, the protective components are located on the top, side, or bottom of the cabinet.

[0021] A converter, comprising:

[0022] Crowbar resistor;

[0023] In the aforementioned cabinet, the pry bar resistor is disposed within the mounting cavity.

[0024] The cabinet provided in this application includes a cabinet body and a protective assembly. The cabinet body houses electronic components, and the protective assembly is located outside the cabinet body and connected to it. The protective assembly includes a first cover and a second cover. The first cover is located outside the second cover, and a waterproof cavity is formed between the first and second covers. The inner cavity of the second cover serves as a mounting cavity, where electronic components such as pry bars and resistors are arranged. The first cover includes a first heat dissipation area, on which at least one first heat dissipation channel connecting the outside to the waterproof cavity is formed. The second cover includes a second heat dissipation area, on which at least one second heat dissipation channel connecting the waterproof cavity and the mounting cavity is formed. When external airflow or liquid enters the second cover, it must pass through the first heat dissipation channel, the waterproof cavity, and the second heat dissipation channel sequentially before entering the mounting cavity. The first and second covers provide double-layer protection against external liquids such as rainwater and seawater. Specifically, the first cover isolates most external liquids, while a small portion of liquid, after passing through the first heat dissipation channel, must then pass through the waterproof cavity and the second heat dissipation channel sequentially before entering the mounting cavity, thus extending the waterproof path and further waterproofing the electronic components within the mounting cavity.

[0025] Compared to related technologies, the cabinet provided in this application arranges electronic components such as pry bars and resistors on the outside of the cabinet by setting protective components on the outside of the cabinet. This allows the electronic components such as pry bars and resistors to be directly installed outside the cabinet without occupying internal space. At the same time, the heat generated by the electronic components such as pry bars and resistors does not affect the heat dissipation of other components inside the cabinet. The first and second covers achieve a double waterproof effect, which can effectively prevent external liquids from splashing onto the pry bars and resistors, ensuring the waterproof rating and normal operation of the electronic components arranged inside the protective components. In addition, it also has the advantages of simple structure and convenient installation and maintenance.

[0026] The converter provided in this embodiment includes a crowbar resistor and the aforementioned cabinet. The crowbar resistor is housed within a mounting cavity, and a second cover provides safety protection for it. The crowbar resistor is ventilated and cooled through a first and a second heat dissipation channel. The structure is simple and the operation is reliable. Since it includes the aforementioned cabinet, it also possesses the aforementioned structure and beneficial effects, which will not be elaborated further here. Attached Figure Description

For example, the following description uses the first direction X as the length direction of the cabinet, the second direction Z as the height direction of the cabinet, and the third direction Y as the width direction of the cabinet.

[0047] In the accompanying drawings of the embodiments of this application, solid arrows indicate the direction of liquid flow, and dashed arrows indicate the direction of airflow.

[0048] Combination Figure 1 and Figure 2The cabinet disclosed in this application includes a cabinet 100 and a protective component 200. The cabinet 100 is used to house electronic devices. The protective component 200 is disposed outside the cabinet 100 and connected to the cabinet 100. The protective component 200 includes a first cover 210 and a second cover 220. The first cover 210 is disposed outside the second cover 220, and a waterproof cavity 201 is formed between the first cover 210 and the second cover 220. The inner cavity of the second cover 220 serves as a mounting cavity 202, which is used to arrange electronic devices such as pry bars and resistors 400. The first cover 210 includes a first heat dissipation area, and at least one first heat dissipation channel 211 communicating with the outside and the waterproof cavity 201 is formed on the first heat dissipation area. The second cover 220 includes a second heat dissipation area, and at least one second heat dissipation channel 221 communicating with the waterproof cavity 201 and the mounting cavity 202 is formed on the second heat dissipation area.

[0049] When the protective assembly 200 is positioned on top of the cabinet 100, the first cover 210 and the second cover 220 can be cover structures with a bottom opening and a U-shaped cross-section. For example, in combination... Figure 7 The main bodies of the first cover 210 and the second cover 220 can both be cubic structures with bottom openings formed by a top plate and four side plates, which are simple in structure and easy to manufacture. Taking the arrangement direction during use as an example, in order to reduce the ingress of rainwater, the first heat dissipation area is usually arranged on at least one of the four side plates of the first cover 210, and the second heat dissipation area can be arranged on at least one of the top plate and four side plates of the second cover 220. The first heat dissipation channel 211 can be arranged in an array or other manner on the first heat dissipation area, and the second heat dissipation channel 221 can be arranged in an array or other manner on the second heat dissipation area. The main bodies of the first cover 210 and the second cover 220 can also be cylindrical or other shapes, and the cross-sectional shape of the first heat dissipation channel 211 and the second heat dissipation channel 221 can be circular, rectangular or other shapes, which are not limited in this embodiment. In some embodiments, combined with Figure 6 The first cover 210 and the second cover 220 can share the same top plate, that is, a waterproof cavity 201 is formed only between the four side plates of the first cover 210 and the second cover 220 facing each other, which reduces material costs.

[0050] In the embodiments of this application, the electronic devices disposed in the mounting cavity 202 include, but are not limited to, the crowbar resistor 400 or other electronic devices, and the electronic devices disposed in the cabinet 100 include, but are not limited to, rectifiers, inverters or other electronic devices.

[0051] Combination Figure 3 and Figure 4 , Figure 4 for Figure 3The diagram shows the structure after removing the first cover 210 and the second cover 220. The heat dissipation path for the electronic components arranged within the second cover 220 is: mounting cavity 202, second heat dissipation channel 221 or second cover 220, waterproof cavity 201, first heat dissipation channel 211 or first cover 210, and the outside. When external airflow or liquid enters the second cover 220, it must pass through the first heat dissipation channel 211, the waterproof cavity 201, and the second heat dissipation channel 221 sequentially before entering the mounting cavity 202. The first cover 210 and the second cover 220 provide double-layer protection against external liquids such as rainwater and seawater. Specifically, the first cover 210 isolates most external liquids; a small portion of the liquid passes through the first heat dissipation channel 211 and then sequentially through the waterproof cavity 201 and the second heat dissipation channel 221 before entering the mounting cavity 202, thus extending the waterproof path and further waterproofing the electronic components within the mounting cavity 202.

[0052] Compared to related technologies, the cabinet disclosed in this application arranges electronic components such as the pry bar resistor 400 by setting a protective component 200 on the outside of the cabinet 100. This allows the pry bar resistor 400 and other electronic components to be directly placed outside the cabinet 100 without occupying the internal space of the cabinet 100. At the same time, the heat generated by the pry bar resistor 400 and other electronic components does not affect the heat dissipation of other components inside the cabinet 100. The arrangement of the first cover 210 and the second cover 220 achieves a double waterproof effect, which can effectively prevent external liquids from splashing onto the pry bar resistor 400, ensuring the waterproof rating and normal operation of the electronic components arranged inside the protective component 200. In addition, it also has the advantages of simple structure and convenient installation and maintenance.

[0053] To further reduce the probability of liquid from the waterproof cavity 201 entering the mounting cavity 202, the first heat dissipation area and the second heat dissipation area are staggered along the extension direction of the first heat dissipation channel 211, so that the first heat dissipation channel 211 and the second heat dissipation channel 221 can be staggered along the extension direction of the first heat dissipation channel 211. Specifically, the first heat dissipation area and the second heat dissipation area can be partially or completely staggered. For example, combined with Figure 6 and Figure 7 For the technical solution where the first heat dissipation channel 211 extends horizontally, along the height direction of the cabinet 100, the first heat dissipation area can partially overlap with the second heat dissipation area, and the other part can be located below the second heat dissipation area. By partially staggering the first heat dissipation area and the second heat dissipation area, the probability of rainwater passing through the first heat dissipation channel 211, the waterproof cavity 201 and the second heat dissipation channel 221 in sequence along the extension direction of the first heat dissipation channel 211 and entering the installation cavity 202 can be reduced, thereby improving the waterproof effect in the installation cavity 202.

[0054] Combination Figure 8 When the channel path of the first heat dissipation channel 211 is straight, the channel path of the first heat dissipation channel 211 is consistent with the extension direction of the first heat dissipation channel 211; when the channel paths of the first heat dissipation channel 211 and the second heat dissipation channel 221 are curved, the extension direction of the first heat dissipation channel 211 refers to the opening direction of the end of the first heat dissipation channel 211 near the waterproof cavity 201. By setting the first heat dissipation channel 211 and the second heat dissipation channel 221 into an S-shaped or other curved channel structure, the probability of liquid entering the mounting cavity 202 can be effectively reduced. It should be noted that since the first cover 210 and the second cover 220 are usually thin plate structures, the thickness dimension available for arranging the first heat dissipation channel 211 and the second heat dissipation channel 221 is small, and the curved structure hole is difficult to process. Therefore, the first heat dissipation channel 211 and the second heat dissipation channel 221 are usually straight through-hole structures.

[0055] In a further embodiment, since the liquid splashed into the waterproof cavity 201 from the first heat dissipation channel 211 can only change its flow direction under the action of gravity, therefore, combined with Figure 8 Along the extension direction of the first heat dissipation channel 211, the area on the second cover 220 corresponding to the first heat dissipation area is defined as the water-blocking area 220a. In the vertical direction, the area on the second cover 220 directly below the water-blocking area 220a is defined as the flow-guiding area 220b. The area on the second cover 220 other than the water-blocking area 220a and the flow-guiding area 220b is defined as the safety opening area 220c. The second heat dissipation area can be set on the safety opening area 220c. Liquid entering the waterproof cavity 201 from the first heat dissipation channel 211 can usually only splash onto the water-blocking area 220a and the flow-guiding area 220b, and flow downward along the flow-guiding area 220b. It will not flow upward or horizontally along the second cover 220 into the second heat dissipation channel 221, let alone enter the mounting cavity 202, thereby greatly improving the waterproof performance of the electronic devices in the mounting cavity 202.

[0056] Specifically, in some embodiments, along the height direction of the cabinet 100, the second heat dissipation area is set above the water-blocking area 220a. The liquid entering the waterproof cavity 201 from the first heat dissipation channel 211 can only splash onto the water-blocking area 220a at most, and flow from the water-blocking area 220a to the bottom along the outer wall of the second cover 220, but cannot enter the installation cavity 202, thereby greatly improving the waterproof performance.

[0057] To improve waterproofing, the first heat dissipation channel 211 is arranged either downwards or horizontally from the inside of the first cover 210 to the outside. This prevents rainwater from directly entering the first heat dissipation channel 211. For the horizontally arranged first heat dissipation channel 211, it facilitates the entry of horizontally flowing airflow into the mounting cavity 202, improving heat dissipation and reducing the probability of sea waves splashing into the first heat dissipation channel 211. For the downwardly inclined first heat dissipation channel 211, it significantly reduces the risk of rainwater entering the first heat dissipation channel 211. The location and direction of the first heat dissipation channel 211 can be selected according to actual conditions, and this embodiment does not impose any restrictions on this.

[0058] The second heat dissipation channel 221 can be arranged downwards or horizontally from the inside of the second cover 220 to the outside of the second cover 220, thereby effectively preventing rainwater on the outer wall of the second cover 220 from flowing directly into the mounting cavity 202 along the second heat dissipation channel 221, thus improving the waterproof performance of the mounting cavity 202. In this embodiment, the second heat dissipation area can also be provided on the water-blocking area 220a or the flow-guiding area 220b.

[0059] In some embodiments disclosed in this application, combined with Figure 2 and Figure 5The protective component 200 includes a tray 230 and a second bracket 240. The tray 230 is connected to the second cover 220 and closes the bottom opening of the second cover 220. The tray 230 supports the bottom of electronic devices inside the second cover 220 and the mounting cavity 202, and has a drainage hole 231 on the tray 230 that connects the mounting cavity 202 to the outside. The first bracket 250 is disposed between the tray 230 and the cabinet 100, providing a drainage gap 203 between the tray 230 and the cabinet 100. The drainage hole 231 communicates with the drainage gap 203, allowing water condensation inside the second cover 220 to be directly discharged into the drainage gap 203 through the drainage hole 231 on the tray 230. The first bracket 250 can be flexibly fixed to the cabinet 100 and the tray 230 by welding, screwing, pinning, or other methods. During assembly, electronic components such as the pry bar resistor 400 can be pre-installed on the tray 230 before being connected to the first cover 210, the second cover 220, and the cabinet 100, improving assembly efficiency. The first cover 210 is connected and fixed to at least one of the tray 230 or the cabinet 100. The connection between the first cover 210 and the tray 230 allows the protective component 200 to form a structure independent of the cabinet 100, facilitating overall disassembly and maintenance. The drain hole 231 can be located in the middle or other positions of the tray 230, and there can be one or more of them. Furthermore, the top surface of the tray 230 can be configured as a drainage structure inclined towards the drain hole 231, thereby facilitating the drainage of accumulated water on the tray 230.

[0060] Furthermore, combining Figure 2 A second bracket 240 is provided on the tray 230 to support electronic components. The second bracket 240 prevents the electronic components inside the mounting cavity 202 from contacting water accumulated on the tray 230, and also helps to drain water, thereby improving waterproof performance. For example, there can be two symmetrically arranged sets of second brackets 240, each supporting one side of the pry bar resistor 400. The structure is simple and easy to install. The tray 230 and the second bracket 240 can be flexibly fixed together by welding, screwing, pinning, or other methods.

[0061] Combination Figure 2 To prevent water from accumulating in the waterproof cavity 201 and overflowing into the second heat dissipation channel 221, the bottom of the waterproof cavity 201 can communicate with the aforementioned drainage gap 203, allowing water in the waterproof cavity 201 to be directly discharged into the drainage gap 203, thus ensuring the waterproof performance of the waterproof cavity 201. Specifically, in conjunction with Figure 2When both the first cover 210 and the second cover 220 are cover structures with open bottoms, by setting the size of the tray 230 to be adapted to the opening area of ​​the second cover 220 and smaller than the opening area of ​​the first cover 210, the bottom of the waterproof cavity 201 can be misaligned with the tray 230 and directly connected to the drainage gap 203 at the opening area at the bottom of the first cover 210; if the bottom opening area of ​​the first cover 210 is blocked by the tray 230, a water outlet hole can be opened on the tray 230 to realize the connection between the waterproof cavity 201 and the drainage gap 203.

[0062] Combination Figure 6 and Figure 7 The first cover 210 and the second cover 220 can be an integral structure or a separate structure. When it is an integral structure, the first cover 210 can be in a ring shape, and the aforementioned waterproof cavity 201 is formed around the circumferential sidewall of the second cover 220. This facilitates the opening of the first heat dissipation channel 211 and provides a water-blocking effect. The first cover 210 and the second cover 220 can be fixed by welding, screwing, or other methods. When it is a separate structure, the first cover 210 can be directly fitted over the second cover 220, and the first cover 210 and the second cover 220 can be connected and fixed to the cabinet 100 or the tray 230, respectively. At least one of the first cover 210 and the second cover 220 is connected to the cabinet 100. For example, when the first cover 210 and the second cover 220 are separate structures, a first connecting hole 212 and a second connection 222 are respectively provided on the first cover 210 and the second cover 220. The first cover 210 and the second cover 220 are bolted to the tray 230 through the first connecting hole 212 and the second connection 222. The structure is simple and easy to assemble and disassemble.

[0063] Since the electronic components inside cabinet 100 need to be electrically connected to the electronic components inside the second enclosure 220 via cables, therefore, in combination with Figure 2 , Figure 4 and Figure 5Multiple waterproof terminals 300 are provided between the cabinet 100 and the tray 230. The cabinet 100 has a first wiring through-hole 101 connecting the waterproof terminals 300 to the inner cavity of the cabinet 100. The tray 230 has a second wiring through-hole 232 connecting the waterproof terminals 300 to the mounting cavity 202. Cables can pass through the waterproof terminals 300, the first wiring through-hole 101, and the second wiring through-hole 232, allowing cables inside the cabinet 100 to exit and connect to electronic components inside the mounting cavity 202. Simultaneously, the waterproof terminals 300 can lock the passing cables, preventing water leakage at the first wiring through-hole 101 and the second wiring through-hole 232, ensuring the waterproof performance of the cabinet 100 and the mounting cavity 202. The waterproof terminals 300 can either abut against the cabinet 100 and the tray 230, or they can pass through the first wiring through-hole 101 and the second wiring through-hole 232.

[0064] Taking the layout direction in actual use as an example, combined with Figure 9 The protective component 200 can be installed on the top, side, or bottom of the cabinet 100, allowing for flexible placement. Taking the protective component 200 installed on the top of the cabinet 100 as an example, the second bracket 240 is supported between the tray 230 and the top outer wall of the cabinet 100, forming the aforementioned drainage gap 203. The accumulated water flowing out of the drain outlet can eventually flow along the top wall of the cabinet 100 and slide down.

[0065] In some embodiments, combined with Figure 8 A dustproof component 500 is also provided at the second heat dissipation channel 221. The dustproof component 500 includes dustproof cotton, dustproof net and other dustproof parts, which can effectively prevent dust and other debris from entering the installation cavity 202. At the same time, some dustproof parts can also absorb moisture in the air and improve the dryness of the installation cavity 202.

[0066] Combination Figure 9 The converter disclosed in this embodiment includes a crowbar resistor 400 and the aforementioned cabinet. The crowbar resistor 400 is disposed within the mounting cavity 202, and the second cover 220 provides safety protection for the crowbar resistor 400. The crowbar resistor 400 is ventilated and cooled through the first heat dissipation channel 211 and the second heat dissipation channel 221. The structure is simple and the operation is reliable. Since it includes the aforementioned cabinet, it also possesses the aforementioned structure and beneficial effects, which will not be elaborated further here.
