[0045] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0046] Reference will be made below Figures 1 - 10 to describe the heat dissipation device and the electrical equipment according to the embodiments of the present application.

[0047] Among them, the electrical equipment may be equipment such as a grid-connected cabinet, a ring main unit cabinet or a control cabinet that adopts air-cooled heat dissipation.

[0048] As Figure 1 shown, the heat dissipation device 100 provided in the embodiment of the present application is applied to the chassis 200. The chassis 200 of the electrical equipment is provided with an air inlet and an air outlet. A heating member such as a circuit breaker or a reactor can be placed in the chassis 200. The heat dissipation device 100 is installed in the chassis 200 to dissipate heat from the heating member in the chassis 200, thereby improving the operation stability of the electrical equipment.

[0049] As Figure 2 shown, the heat dissipation device 100 includes: a mounting bracket 1, a first fan assembly 2 and a heat dissipation member 3. The first fan assembly 2 and the heat dissipation member 3 are both installed on the mounting bracket 1, and the first fan assembly 2 and the heat dissipation member 3 are disposed on opposite sides of the mounting bracket 1.

[0050] As Figure 1 shown, the mounting bracket 1 is adapted to be installed in the chassis 200. The mounting bracket 1 can divide the installation cavity 223 in the chassis 200 into a plurality of compartments 203. A heating member 201 such as a circuit breaker can be provided in each compartment 203. As Figure 9 shown, the mounting bracket 1 is provided with a first ventilation opening 111, and the first ventilation opening 111 communicates with the compartments 203 on both sides of the mounting bracket 1.

[0051] AsFigure 2 and Figure 9 As shown in Figure 9 , the first fan assembly 2 is slidably mounted on one side of the mounting bracket 1, and the heat dissipation member 3 is mounted on the other side of the mounting bracket 1. The heat dissipation member 3 is communicated with the first ventilation opening 111, the first fan assembly 2 is communicated with the first ventilation opening 111, and the first fan assembly 2 and the heat dissipation member 3 are communicated through the first ventilation opening 111. The first fan assembly 2 forces the air in the chassis 200 to flow through the surface of the radiator, and the heat exchange medium in the radiator exchanges heat with the air to achieve the cooling of the installation cavity 223.

[0052] Exemplarily, the heat dissipation member 3 may be a heat dissipation device such as a fin radiator, a liquid-cooled radiator or a heat pipe vapor chamber.

[0053] Among them, the first fan assembly 2 may be of a drawer type structure, and the first fan assembly 2 is slidably engaged with the mounting bracket 1 in a pulling manner.

[0054] Exemplarily, the first fan assembly 2 and the mounting bracket 1 may be slidably engaged through a slide rail and a slider, or the first fan assembly 2 and the mounting bracket 1 may be slidably engaged through a chute and a slider, or the first fan assembly 2 and the mounting bracket 1 may be slidably engaged through a sleeve and a shaft, etc.

[0055] In this embodiment, by setting the first fan assembly 2 to be slidably engaged with the mounting bracket 1, when the mounting bracket 1 is installed in the chassis 200, the first fan assembly 2 can be slidably engaged with the mounting bracket 1 from the side of the mounting bracket 1, making full use of the side space of the mounting bracket 1. Thus, there is no need to operate and disassemble the screws from the front direction of the first fan assembly 2, and there is no need to reserve an installation space around the first fan assembly 2, which is easy to disassemble and maintain the first fan assembly 2, convenient for the use of the cooling fan, and reduces the occupation of the effective space in the chassis 200.

[0056] As Figure 7 shown in Figure 7 , the mounting bracket 1 is provided with a first positioning member 14, and the first fan assembly 2 is provided with a second positioning member 211 that cooperates with the first positioning member 14. After the first positioning member 14 and the second positioning member 211 are positioned and cooperated, the position of the first fan assembly 2 is limited, and the first fan assembly 2 stops sliding. The first positioning member 14 and the second positioning member 211 play a role in positioning and fixing, which can increase the stability of the connection between the mounting bracket 1 and the first fan assembly 2, and reduce the situation of the first fan assembly 2 shaking and shifting relative to the mounting bracket 1.

[0057] Exemplarily, as Figure 7 and Figure 8 shown in Figure 7 and Figure 8 , the first positioning member 14 and the second positioning member 211 are engaged with each other through a plugging hole 141 and a plug 2111; or, the first positioning member 14 and the second positioning member 211 are engaged with each other through a key and a keyway.

[0058] According to the heat dissipation device 100 provided in the embodiment of the present application, on the one hand, by setting the first fan assembly 2 to slide with the mounting bracket 1, when the mounting bracket 1 is installed in the chassis 200, the first fan assembly 2 can slide with the mounting bracket 1 from the side of the mounting bracket 1, making full use of the lateral space of the mounting bracket 1, thereby eliminating the need to operate and remove the screws from the front direction of the first fan assembly 2, and eliminating the need to reserve installation space on the surrounding side of the first fan assembly 2, which facilitates the installation and maintenance of the first fan assembly 2 in a narrow installation space and reduces the encroachment on the effective space in the chassis 200; on the other hand, by setting the first positioning member 14 and the second positioning member 211, the positioning and cooperation of the first fan assembly 2 and the mounting bracket 1 can be achieved, and the first positioning member 14 and the second positioning member 211 play a positioning and fixing role, which can increase the stability of the connection between the mounting bracket 1 and the first fan assembly 2, and reduce the shaking and displacement of the first fan assembly 2 relative to the mounting bracket 1.

[0059] In some embodiments, as Figure 7 and Figure 8 As shown, one of the first positioning member 14 and the second positioning member 211 is a plug hole 141 , and the other of the first positioning member 14 and the second positioning member 211 is a plug pin 2111 .

[0060] Among them, Figure 8 As shown, the latch 2111 includes a connecting portion 2112 and a guide portion 2113 connected to each other. The outer diameter of the guide portion 2113 decreases in a direction from close to the connecting portion 2112 to away from the connecting portion 2112. By reducing the outer diameter of the guide portion 2113, it is easy to ensure that the latch 2111 can be smoothly inserted into or withdrawn from the plug hole 141, and at the same time provide a certain guiding effect to prevent the latch 2111 from deflecting during the installation process, thereby reducing the difficulty of assembly.

[0061] In some embodiments, as Figure 7 and Figure 8 As shown, the first positioning member 14 is a plug hole 141 , and the second positioning member 211 is a plug pin 2111 .

[0062] In some embodiments, as Figure 7 and Figure 8 As shown, the first positioning members 14 include multiple first positioning members 14, which are arranged at intervals along the extension direction of the mounting bracket 1, and the second positioning members 211 include multiple first positioning members 14 and multiple second positioning members 211 are arranged one-to-one, thereby further increasing the stability of the connection between the mounting bracket 1 and the first fan assembly 2.

[0063] In some embodiments, as Figure 3As shown, the mounting bracket 1 includes: a spacer plate 11 and a first mounting member 12 . The spacer plate 11 is used to be connected to the chassis 200 . The spacer plate 11 is provided with a first ventilation opening 111 .

[0064] like Figure 1 As shown, the partition plate 11 is suitable for installation in the chassis 200. The partition plate 11 can divide the installation cavity 223 in the chassis 200 into multiple compartments 203. Exemplarily, the partition plate 11 and the chassis 200 can be connected by plug-in connection, threaded connection or sliding connection.

[0065] like Figure 6 and Figure 7 As shown, the first mounting member 12 is mounted on the partition plate 11 and protrudes from the surface of the partition plate 11 . The first mounting member 12 is provided with a first positioning member 14 .

[0066] In some embodiments, the latch 2111 is detachably connected to the first mounting member 12. For example, the latch 2111 and the first mounting member 12 can be connected by plugging, threading, or snapping.

[0067] The first mounting member 12 can be the end point of the sliding stroke of the first fan assembly 2. The first mounting member 12 protrudes from the surface of the partition plate 11 to limit the first fan assembly 2. The first positioning member 14 provided on the first mounting member 12 can be positioned and matched with the second positioning member 211 of the first fan assembly 2 to position the first fan assembly 2 and reduce the shaking and displacement of the first fan assembly 2 during operation.

[0068] The first mounting member 12 may be a flange of the first vent 111, or a rib or boss structure. The first mounting member 12 and the partition plate 11 may be connected by threaded connection, welding, or integral molding.

[0069] In some embodiments, the first mounting member 12 includes a first portion 121 and a second portion 122 . The first portion 121 is connected to the partition plate 11 . The second portion 122 is bent relative to the first portion 121 and protrudes toward a side away from the partition plate 11 . The second portion 122 is provided with a first positioning member 14 .

[0070] In this embodiment, if Figure 6 As shown, by configuring the first mounting member 12 as an L-shaped structure, the stability of the connection between the first mounting member 12 and the spacer plate 11 can be increased.

[0071] In some embodiments, as Figure 4 and Figure 10As shown, the mounting bracket 1 also includes: a second mounting member 13, which is mounted on the partition plate 11. The second mounting member 13 can be connected to the partition plate 11 by threaded connection, welding or one-piece molding connection, and the heat sink 3 is connected to the partition plate 11 through the second mounting member 13.

[0072] The second mounting member 13 is disposed around the first vent 111 to guide the airflow passing through the first vent 111 , thereby increasing the airflow passing through the heat sink 3 and improving the heat dissipation effect of the heat sink 3 .

[0073] The second mounting member 13 may be connected to the heat sink 3 by a threaded connection, a plug-in connection, or other connection methods.

[0074] Among them, such as Figure 4 and Figure 10 As shown, a protruding connection piece 132 is provided at one end of the second mounting member 13 facing away from the partition plate 11 , and the protruding connection piece 132 is connected to the heat sink 3 to separate the other part of the second mounting member 13 not provided with the protruding connection piece 132 from the heat sink 3 to form a ventilation gap 131 .

[0075] In this embodiment, by setting the ventilation gap 131, the ventilation gap 131 can allow air to circulate between the heat sink 3 and the mounting bracket 1. When the ventilation volume is small, such as when the cooling fins of the heat sink 3 are blocked, the first fan assembly 2 can force the airflow to pass through the ventilation gap 131, which helps to improve the heat dissipation efficiency; at the same time, the ventilation gap 131 can also reduce the heat conduction between the heat sink 3 and the partition plate 11, thereby improving the heat dissipation effect; in addition, the ventilation gap 131 can also reduce the vibration and noise generated by the contact between the heat sink 3 and the partition plate 11.

[0076] In some embodiments, as Figure 9 As shown, the edge of the first vent 111 is folded to form a first sliding member 112. The edge of the first vent 111 is folded or bent to form a protruding structure. This design can increase the strength of the first vent 111 and provide a mechanical structure that can slide with the first fan assembly 2.

[0077] like Figure 9 As shown, the first sliding member 112 extends along a first direction, which is a direction in which the first fan assembly 2 slides relative to the mounting bracket 1 , and the first fan assembly 2 slides along the extending direction of the first sliding member 112 .

[0078] like Figure 6 As shown, the first fan assembly 2 includes a mounting base 21 and a fan 22. The fan 22 is installed on the mounting base 21. The mounting base 21 is a supporting structure for the fan 22, and the fan 22 is a device for forcing air flow to improve the heat dissipation efficiency of the heat sink 3.

[0079] like Figure 8 As shown, the mounting base 21 is provided with a second vent 212 communicating with the first vent 111 . This design allows air to flow in from the first vent 111 and the second vent 212 and be accelerated by the fan 22 to form an effective air circulation.

[0080] like Figure 5 and Figure 8 As shown, the end of the mounting base 21 is folded to form a second sliding member 213. The second sliding member 213 can be similar to the first sliding member 112 in structure. The second sliding member 213 and the first sliding member 112 can be slidably matched to facilitate the installation and disassembly of the first fan assembly 2 and the mounting bracket 1.

[0081] The second sliding member 213 is slidably matched with the first sliding member 112 to allow the first fan assembly 2 to slide on the mounting bracket 1 , thereby achieving assembly of the first fan assembly 2 and the chassis 200 .

[0082] Exemplarily, the sliding fit between the second sliding member 213 and the first sliding member 112 may be achieved through a guide rail, a slider or other sliding mechanisms to improve the stability and reliability of the connection between the first fan assembly 2 and the mounting bracket 1 .

[0083] In some embodiments, as Figure 5 As shown, the first sliding member 112 includes a first flange 1121 and a second flange 1122 .

[0084] The first flange 1121 is a portion formed by folding the edge of the first vent 111 outward. The first flange 1121 provides an initial edge or boundary for sliding fit.

[0085] The second flange 1122 is formed by folding outward again relative to the first flange 1121 and is disposed opposite the spacer 11. The design of the second flange 1122 can increase the strength and stability of the structure and prevent the mounting base 21 from falling away from the spacer 11.

[0086] The first flange 1121 , the second flange 1122 and the partition plate 11 form a first sliding groove 1123 . The first sliding groove 1123 provides a sliding path for the second sliding member 213 .

[0087] The second sliding member 213 includes a third flange 2131 and a fourth flange 2132 . The third flange 2131 is a portion folded relative to the mounting base 21 toward a side away from the fan 22 . The third flange 2131 provides an edge or boundary for sliding fit.

[0088] The fourth flanging 2132 is a part formed by folding inward relative to the third flanging 2131, and the fourth flanging 2132 is disposed opposite to the mounting base plate 21. The design of the fourth flanging 2132 can increase the strength and stability of the structure. The fourth flanging 2132 is in surface contact with the spacer plate 11, which can increase the stability when the first sliding member 112 and the second sliding member 213 slide relative to each other, and at the same time can prevent the mounting base plate 21 from falling off the first chute 1123.

[0089] The third flanging 2131, the fourth flanging 2132 and the mounting base plate 21 form a second chute 2133, and the second chute 2133 provides a sliding path for the first sliding member 112.

[0090] The fourth flanging 2132 is located within the first chute 1123, and the fourth flanging 2132 can slide along the first chute 1123. The second flanging 1122 is located within the second chute 2133, and the second flanging 1122 can slide along the second chute 2133, thereby allowing the first fan assembly 2 to move on the mounting bracket 1.

[0091] In this embodiment, as Figure 5 shown, the first chute 1123 and the second chute 2133 form an interlocking structure, which can increase the stability and reliability of the sliding fit between the first fan assembly 2 and the mounting bracket 1. And in the case where the mounting bracket 1 is placed in different directions, the first chute 1123 and the second chute 2133 limit and fix each other, which can reduce the risk of the first fan assembly 2 separating and falling off the mounting bracket 1.

[0092] In some embodiments, as Figure 5 shown, the groove width of the first chute 1123 is greater than the groove width of the second chute 2133.

[0093] The first chute 1123 is a sliding chute formed by the spacer plate 11, and the second chute 2133 is a sliding chute formed by the mounting base plate 21 of the first fan assembly 2. The first chute 1123 is set with a larger groove width to provide more space, so that the second sliding member 213 (i.e., the second sliding member 213 of the first fan assembly 2) has more freedom of movement within the first chute 1123, reducing the difficulty of installing, adjusting or disassembling the first fan assembly 2.

[0094] In some embodiments, as Figure 5 shown, the fan 22 includes a fan body 221 and a housing 222. The fan body 221 includes air supply devices such as a motor and a fan impeller. The fan body 221 can generate an air flow to achieve heat dissipation.

[0095] As Figure 3As shown, the housing 222 is installed on the mounting base plate 21 and forms a mounting cavity 223 with the mounting base plate 21. The fan body 221 is installed in the mounting cavity 223. The mounting cavity 223 provides a protection space for the fan body 221 and also facilitates the installation and maintenance of the fan 22.

[0096] The housing 222 has a plurality of openings, which can be air inlets or outlets, for guiding air flow.

[0097] In some embodiments, as Figure 3 shown, the housing 222 includes a connected side plate 2222 and a panel 2221. The side plate 2222, the panel 2221 and the mounting base plate 21 jointly define the mounting cavity 223. The fan body 221 is installed in the mounting cavity 223. A handle device is provided on the front side of the panel 2221 along the first direction.

[0098] In this embodiment, by providing the handle device, it is convenient to pull the first fan assembly 2 out of the mounting bracket 1, further reducing the disassembly and installation difficulty of the first fan assembly 2 and the chassis 200.

[0099] In some embodiments, as Figure 3 shown, the panel 2221 is installed on the front side of the side plate 2222 and the bottom plate along the first direction, and the outer edge of the panel 2221 protrudes from the side plate 2222 and the bottom plate.

[0100] Among them, the mounting bracket 1 and the chassis 200 are shaped for the mounting slot for installing the first fan assembly 2. The outer edge of the panel 2221 plays a limiting role. The area of the panel 2221 is larger than the notch area of the mounting slot to prevent the first fan assembly 2 from sliding into the mounting slot during the sliding process along the first direction. At the same time, one side of the chassis 200 is a complete wall surface, increasing the sealing performance and safety, and reducing the entry of dust.

[0101] In some embodiments, as Figure 3 shown, the fan 22 further includes a wind guide shell 23 with both ends open. The wind guide shell 23 is used to guide and optimize air flow. Both ends of the wind guide shell 23 are open, and the two ends of the wind guide shell 23 are respectively communicated with the fan body 221 and the second ventilation port 212, that is, the two ends of the wind guide shell 23 are respectively connected with the fan body 221 and the heat dissipation member 3.

[0102] The wind guide shell 23 is arranged between the fan body 221 and the second ventilation port 212, which helps to effectively guide the air flow generated by the fan body 221 to the second ventilation port 212, thereby improving the heat dissipation efficiency of the heat dissipation member 3.

[0103] Among them, the ventilation area of the opening of the wind guide shell 23 close to the fan body 221 is smaller than the ventilation area of the opening of the wind guide shell 23 close to the second ventilation port 212.

[0104] The air guide housing 23 has a smaller ventilation area at one end close to the fan body 221, which can increase the air flow velocity passing through this end, thereby improving the efficiency of the fan 22 and reducing the noise generated during air flow.

[0105] The air guide housing 23 has a larger ventilation area at one end close to the second ventilation opening 212, which helps to distribute the air flow more evenly and reduce the eddy current and air flow non-uniformity.

[0106] In this embodiment, by setting the ventilation area of the opening of the air guide housing 23 close to the fan body 221 to be smaller than the ventilation area of the air guide housing 23 close to the second ventilation opening 212, the air flow generated by the fan body 221 can be more effectively guided to the area of the heat dissipation member 3 that needs to be cooled, thereby improving the efficiency of the entire heat dissipation device 100. At the same time, the air guide housing 23 can also provide additional structural stability and reduce the probability of physical damage to the fan body 221.

[0107] In some embodiments, as Figure 9 shown, the mounting bracket 1 is further provided with a third ventilation opening 113, and the third ventilation opening 113 communicates with the compartments 203 on both sides of the mounting bracket 1.

[0108] The heat dissipation device 100 further includes a second fan assembly 4. The first fan assembly 2 and the second fan assembly 4 are installed on opposite sides of the mounting bracket 1. The design of the first fan assembly 2 and the second fan assembly 4 allows the two fan assemblies to work together. The first fan assembly 2 and the second fan assembly 4 can be set to have different wind directions to improve the heat dissipation efficiency.

[0109] The second fan assembly 4 communicates with the third ventilation opening 113. The second fan assembly 4 is in communication with the air in the adjacent compartment 203 through the third ventilation opening 113. The second fan assembly 4 can inhale the air in the adjacent compartment 203 from the third ventilation opening 113, or discharge the air in the compartment 203 where the second fan assembly 4 is located to the third ventilation opening 113.

[0110] The wind directions of the first fan assembly 2 and the second fan assembly 4 are opposite, and the first fan assembly 2 and the second fan assembly 4 can work together to optimize the air flow and heat dissipation effect.

[0111] Exemplarily, the first fan assembly 2 can discharge the air in the compartment 203 from the first ventilation opening 111 and the second ventilation opening 212, pass through the heat dissipation member 3, and then discharge it to the compartment 203 where the second fan assembly 4 is located; at the same time, the second fan assembly 4 can discharge the air in the compartment 203 where it is located from the third ventilation opening 113, and then discharge it to the compartment 203 where the first fan assembly 2 is located, increasing the air flow velocity in the chassis 200 and improving the heat dissipation efficiency.

[0112] Exemplarily, the first fan assembly 2 can draw air from the compartment 203 where the second fan assembly 4 is located through the first vent 111 and the second vent 212, pass through the heat sink 3, and then draw the air into the compartment 203 where the first fan assembly 2 is located; at the same time, the second fan assembly 4 can draw air from the compartment 203 where the first fan assembly 2 is located through the third vent 113, and then discharge it into the compartment 203 where the second fan assembly 4 is located, thereby increasing the speed of gas flow in the chassis 200 and improving the heat dissipation efficiency.

[0113] In this embodiment, the opposite wind directions of the two fan assemblies may help reduce noise and vibration because they can offset a portion of the noise and vibration generated by the airflow.

[0114] In some embodiments, the fan body 221 may be a centrifugal fan that can absorb air; the second fan assembly 4 may be an axial flow fan that can blow air.

[0115] like Figure 1 As shown, an embodiment of the present application further provides an electrical device, including a chassis 200 and a heat dissipation device 100 of any of the above embodiments, wherein the heat dissipation device 100 is installed in the chassis 200 to dissipate heat from a heating element 201 in the chassis 200 .

[0116] According to the electrical equipment provided in the embodiments of the present application, by setting the heat dissipation device 100 in any of the above embodiments, on the one hand, by setting the first fan assembly 2 to slide with the mounting bracket 1, when the mounting bracket 1 is installed in the chassis 200, the first fan assembly 2 can slide with the mounting bracket 1 from the side of the mounting bracket 1, making full use of the lateral space of the mounting bracket 1, so that there is no need to operate the removal screws from the front direction of the first fan assembly 2, and there is no need to reserve installation space on the surrounding side of the first fan assembly 2, which is convenient for installing and maintaining the first fan assembly 2 in a narrow installation space, reducing the encroachment on the effective space in the chassis 200; on the other hand, by setting the first positioning member 14 and the second positioning member 211, the positioning and matching of the first fan assembly 2 and the mounting bracket 1 can be achieved, and the first positioning member 14 and the second positioning member 211 play a positioning and fixing role, which can increase the stability of the connection between the mounting bracket 1 and the first fan assembly 2, and reduce the shaking and displacement of the first fan assembly 2 relative to the mounting bracket 1.

[0117] In some embodiments, the chassis 200 forms an assembly cavity 202 , which can accommodate and protect internal electronic components.

[0118] like Figure 1As shown, the mounting bracket 1 of the heat dissipation device 100 is installed in the assembly cavity 202 and divides the assembly cavity 202 into multiple compartments 203. There are multiple heat generating components 201, and the multiple heat generating components 201 are respectively arranged in the multiple compartments 203, which can reduce the occurrence of heat concentration and the risk of overheating of a single component.

[0119] In this embodiment, the multiple heat generating components 201 being respectively arranged in the multiple compartments 203 occupies a large amount of space in the assembly cavity 202. The heat dissipation device 100 is located between two adjacent compartments 203. The first fan assembly 2 can be installed in a narrow space by slidingly cooperating with the mounting bracket 1, without reserving an installation space around the first fan assembly 2, reducing the occupation of the effective space inside the chassis 200.
