Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a fan cabinet and a heat dissipation system. Background Technology

[0002] Fan cabinets are used to install fans. Low-temperature air exchanges heat with heat source equipment to form high-temperature air. The fan can introduce this high-temperature air into the heat exchange equipment through ducts, thereby reducing the temperature of the heat source equipment. The heat exchange equipment allows the high-temperature air to exchange heat with cooling water, transforming it into low-temperature air. The fan can then return this low-temperature air to the heat source equipment, thus forming a circulating cooling system.

[0003] Currently, multiple fans are fixed in the fan cabinet, which is placed above the heat exchanger cabinet.

[0004] However, since each fan is fixed in a fan cabinet, when a fan needs to be maintained, the entire fan cabinet needs to be moved from the heat exchanger cabinet to the ground. After the fan maintenance is completed, the entire fan cabinet is moved back to the heat exchanger cabinet. Because the fan cabinet is heavy and bulky, it is difficult to move the entire fan cabinet, resulting in low efficiency of fan maintenance. Utility Model Content

[0005] In view of this, the fan cabinet and heat dissipation system provided by this utility model can improve the maintenance efficiency of the fan.

[0006] According to a first aspect of the present invention, a fan cabinet is provided, comprising: a cabinet body, at least two cover plates, and at least two fan mounting brackets; an air inlet is provided at the bottom of the cabinet body, and an air outlet is provided on the front side panel of the cabinet body; at least two fan receiving cavities are provided inside the cabinet body, and guide rails are provided on the side walls of the fan receiving cavities, the guide rails being used to support the fan mounting brackets and to allow the fan mounting brackets to slide in a direction perpendicular to the rear side of the cabinet body under the action of external force; the fan mounting brackets are used to fix and install fans; the cover plates are detachably connected to the rear side of the cabinet body, and after the cover plates are connected to the rear side of the cabinet body, the fan mounting brackets are enclosed in the fan receiving cavities, and different cover plates correspond to different fan receiving cavities.

[0007] In one possible implementation, the cabinet includes at least one partition plate parallel to the left and right side walls of the cabinet and connected to the top and front side panels of the cabinet. The at least one partition plate divides the internal space of the cabinet into at least two fan receiving cavities. The guide rail includes two sub-guide rails respectively disposed on two opposite side walls of the fan receiving cavities.

[0008] In one possible implementation, the sub-guide rail includes a fixed part and a support part that are vertically connected; on a cross section perpendicular to the extension direction of the sub-guide rail, the cross-sectional shape of the connected fixed part and the support part is L-shaped; the fixed part is connected to the side wall of the fan housing cavity, and the support part is used to support the fan mounting bracket.

[0009] In one possible implementation, the sub-guide rail further includes a slide bar connected to the support portion. The slide bar is located between the top surface of the support portion and the fan mounting bracket, and the fan mounting bracket slides on the slide bar under the action of an external force.

[0010] In one possible implementation, the slide bar is provided with at least two countersunk holes, the support portion is provided with screw holes opposite to the countersunk holes, and a screw passing through the countersunk holes is connected to the corresponding screw hole, the head of the screw being lower than or flat to the contact surface between the slide bar and the fan mounting bracket.

The slide bar is provided with a second through hole corresponding to the first through hole. The fan mounting bracket is provided with a third through hole. After the fan mounting bracket slides on the slide bar to the mounting position, bolts passing through the third through hole, the second through hole, and the first through hole in sequence are connected to the nut to connect the fan mounting bracket to the support portion.

[0012] In one possible implementation, the fan cabinet further includes at least one damper;

[0013] Along a direction perpendicular to the side wall of the fan housing cavity, the width of the slide bar is smaller than the width of the support portion, and within the same fan housing cavity, the distance between two supports is smaller than the distance between two slide bars; the damper is disposed in the fan housing cavity, and the damper is located between the air inlet and the fan mounting bracket; guide bars are respectively provided on the top of the left and right sides of the damper, and the guide bars are at least partially located in the gap between the fan mounting bracket and the support portion, and the guide bars allow the damper to slide in a direction perpendicular to the rear side of the cabinet under the action of external force; the damper includes at least one damper plate, and the damper plate is used to rotate around an axis under the action of external force to adjust the opening of the air inlet.

[0014] In one possible implementation, a positioning pin is provided on the front side wall of the damper, and a positioning element is provided on the front side panel of the cabinet, the positioning element having a positioning hole; when the damper slides to the installation position in a direction perpendicular to the rear side of the cabinet under the action of external force, the positioning pin is located in the positioning hole; in a direction perpendicular to the sliding direction of the damper, the cooperating positioning pin and the positioning hole restrict the relative position of the damper and the cabinet.

[0015] In one possible implementation, the fan cabinet further includes a fixing plate; when the damper is in the mounting position, the fixing plate is bolted to the fan mounting bracket, and the fixing plate is bolted to the front side plate of the damper.

[0017] As described in the above technical solution, the cabinet contains multiple isolated fan housing cavities. Guide rails are installed on the side walls of each fan housing cavity, allowing the fan mounting brackets to slide along these rails. When maintenance is required on a specific fan, the cover plate corresponding to that fan housing cavity can be removed. Then, the fan and its connected mounting bracket can be pulled out from the rear side of the cabinet. After maintenance, the fan and its connected mounting bracket are pushed back into the fan housing cavity from the rear side of the cabinet, and the cover plate is then reattached to the cabinet. Therefore, fan maintenance does not require moving the entire fan cabinet; only the fan and its connected mounting bracket needing maintenance need to be moved. Compared to moving the entire fan cabinet, moving the fan and its connected mounting bracket individually saves time and effort, thus improving fan maintenance efficiency.

Detailed Implementation

[0033] As mentioned earlier, the fans are mounted inside the fan cabinet using fan mounting brackets, which are fixed to the cabinet body. Multiple fans are typically housed within the fan cabinet. The fan cabinet is usually placed above a heat exchanger cabinet, which contains the heat exchanger. When maintenance is required on a particular fan, the entire fan cabinet must be moved from the heat exchanger cabinet to the ground. After the fan maintenance is completed, the entire fan cabinet is moved back onto the heat exchanger cabinet. Because multiple fans are installed inside the fan cabinet, and the cabinet itself is quite heavy and bulky, moving the entire fan cabinet is difficult and time-consuming, resulting in low efficiency for fan maintenance.

[0034] In this embodiment of the utility model, the fan mounting bracket and the cabinet are designed to be separate. The fan is mounted on the fan mounting bracket. When maintenance is required on a certain fan, the fan and its corresponding fan mounting bracket can be removed separately from the cabinet. After the fan maintenance is completed, the fan and its corresponding fan mounting bracket can be put back into the cabinet. There is no need to move the entire fan cabinet from the heat exchanger cabinet to the ground. Moving the fan mounting bracket separately is less difficult and takes less time than moving the entire fan cabinet, thereby improving the efficiency of fan maintenance.

[0035] The fan cabinet and heat dissipation system provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Figure 1 and Figure 2 This is a schematic diagram of a fan cabinet 10 according to an embodiment of this utility model. Figure 1 and Figure 2 As shown, the fan cabinet 10 includes a cabinet body 11, at least two cover plates 12, and at least two fan mounting brackets 13. As an example, Figure 1 and Figure 2 The fan cabinet 10 shown includes three covers 12 and three fan mounting brackets 13. For clarity, the corresponding components are... Figure 1 One fan mounting bracket 13 was removed. Figure 2 One fan mounting bracket 13 and one cover plate 12 were removed. In other embodiments, the fan cabinet 10 may include a suitable number of cover plates 12 and fan mounting brackets 13, and the number of cover plates 12 and fan mounting brackets 13 included in the fan cabinet 10 is equal. For example, the fan cabinet 10 may include two, four or more cover plates 12.

[0037] The cabinet 11 has an air inlet at its bottom and an air outlet on its front panel 111. The cabinet 11 contains at least two fan housings, each with a guide rail 112 on its side wall. The guide rail 112 supports the fan mounting bracket 13 and allows the fan mounting bracket 13 to slide along the direction perpendicular to the rear side of the cabinet 11 under external force.

[0038] Each fan housing cavity can accommodate one fan mounting bracket 13. Figure 1 and Figure 2 Three fan housing cavities are shown. Guide rails 112 are fixedly installed on the side walls of the fan housing cavities. The extension direction of the guide rails 112 is perpendicular to the rear side of the cabinet 11. The rear side of the cabinet 11 is parallel to the front side. A front side plate 111 is provided on the front side of the cabinet 11.

[0039] The fan mounting bracket 13 is used to fix the fan 20 in place. For example, the fan 20 can be fixed to the fan mounting bracket 13 with bolts. The inlet channel of the fan 20 is opposite to the air inlet located at the bottom of the cabinet 11. When the fan 20 rotates, it draws air into the fan housing cavity from the air inlet and drives the air in the fan housing cavity to flow out from the air outlet located on the front side panel 111.

[0040] The cover plate 12 is detachably connected to the rear side of the cabinet 11, for example, by screws. Each cover plate 12 corresponds to a fan housing cavity. After the cover plate 12 is connected to the rear side of the cabinet 11, the fan mounting bracket 13 can be enclosed in the corresponding fan housing cavity. At this time, the fan housing cavity, except for the corresponding air inlet and outlet, is a relatively sealed space. After the cover plates 12 of the fan cabinet 10 are connected to the rear side of the cabinet 11, each cover plate 12 constitutes the rear side panel of the cabinet 11.

[0041] In this embodiment of the invention, the cabinet 11 is provided with multiple isolated fan receiving cavities. Guide rails 112 are provided on the side walls of each fan receiving cavity, allowing the fan mounting bracket 13 for mounting the fan 20 to slide on the guide rails 112. When maintenance is required on a particular fan 20, the cover plate 12 corresponding to the fan receiving cavity containing that fan 20 can be removed. Then, the fan 20 and the connected fan mounting bracket 13 can be pulled out from the rear side of the cabinet 11. After maintenance of the fan 20 is completed, the fan 20 and the connected fan mounting bracket 13 can be pushed back into the fan receiving cavity from the rear side of the cabinet 11, and then the cover plate 12 can be reattached to the cabinet 11. Therefore, the maintenance of the fan 20 does not require moving the entire fan cabinet 10; only the fan 20 and the connected fan mounting bracket 13 need to be moved. Compared to moving the entire fan cabinet 10, moving the fan 20 and the connected fan mounting bracket 13 separately saves time and effort, thereby improving the maintenance efficiency of the fan 20.

[0042] In one possible implementation, such as Figure 3 The schematic diagram of the fan cabinet 10 shown shows that the cabinet body 11 includes at least one partition plate 113. The partition plate 113 is parallel to the left side wall 114 and the right side wall 115 of the cabinet body 11. The partition plate 113 is connected to the top plate 116 and the front side plate 111 of the cabinet body 11. The at least one partition plate 113 divides the internal space of the cabinet body 11 into at least two fan receiving cavities.

[0043] exist Figure 3 In the example shown, the cabinet 11 includes two partitions 113, which divide the internal space of the cabinet 11 into three fan housing cavities. The different fan housing cavities may have the same or different dimensions. When multiple fans 20 of the same model are installed in the fan cabinet 10, each fan housing cavity has the same size. When multiple fans 20 of different models are installed in the fan cabinet 10, the dimensions of each fan housing cavity may be different.

[0044] like Figure 4 The schematic diagram of the fan cabinet 10 shown shows that the guide rail 112, which is disposed in a fan housing cavity, includes two sub-guide rails 1121, which are respectively disposed on two opposite side walls of the fan housing cavity. The side walls of the fan housing cavity can be the left side wall 114, the right side wall 115, or the partition plate 113 of the cabinet body 11.

[0045] exist Figure 4 In the example shown, from left to right, in the left fan housing cavity, one sub-guide rail 1121 is disposed on the left side wall 114 of the cabinet 11, and another sub-guide rail 1121 is disposed on the left side wall of the left partition plate 113. In the middle fan housing cavity, one sub-guide rail 1121 is disposed on the right side wall of the left partition plate 113, and another sub-guide rail 1121 is disposed on the left side wall of the right partition plate 113. In the right fan housing cavity, one sub-guide rail 1121 is disposed on the right side wall of the right partition plate 113, and another sub-guide rail 1121 is disposed on the right side wall 115 of the cabinet 11.

[0046] In one example, the partition plate 113 can be a double-layer structure. For example, the partition plate 113 can be composed of two stacked steel plates. The two steel plates are relatively fixedly connected by welding, riveting or bolting to ensure that the partition plate 113 has sufficient strength to support the fan mounting bracket 13.

[0047] In this embodiment of the invention, at least one partition plate 113 divides the internal space of the cabinet 11 into at least two fan housing cavities. The fan housing cavities are relatively isolated from each other, so that the operation of different fans 20 does not affect each other. This allows for the control of only some fans 20, which is suitable for application scenarios where the fan cabinet 10 is equipped with one or more redundant fans. Each fan housing cavity is provided with two sub-guide rails 1121, which are set on two opposite side walls of the fan housing cavity. The left and right sides of the lower end of the fan mounting bracket 13 abut against one sub-guide rail 1121, ensuring the reliability of the fan mounting bracket 13 in bearing the load and ensuring the stability of the fan mounting bracket 13 when sliding on the guide rails 1121.

[0048] In one possible implementation, Figure 5A schematic diagram of a fan cabinet 10 according to an embodiment of the present invention is shown, wherein the lower dashed circle is a partial enlarged view of the upper dashed circle. Figure 5 As shown, the sub-guide rail 1121 includes a fixing part 31 and a supporting part 32 connected vertically. Both the fixing part 31 and the supporting part 32 can be strip-shaped structures. One long side of the fixing part 31 is perpendicularly connected to one long side of the supporting part 32. On a cross-section perpendicular to the extension direction of the sub-guide rail 1121, the connected fixing part 31 and supporting part 32 have an L-shaped cross-section. The fixing part 31 and supporting part 32 can be integrally formed or connected by welding. This embodiment of the invention does not limit the connection method of the fixing part 31 and supporting part 32.

[0049] The fixing part 31 can be connected to the side wall of the fan housing cavity, such as the left side wall 114, right side wall 115, or partition plate 113 of the cabinet 11. Figure 4 Of the sub-guide rails 1121 shown, one sub-guide rail 1121 has a fixing part 31 that is connected to the left side wall 114 of the cabinet 11, one sub-guide rail 1121 has a fixing part 31 that is connected to the right side wall of the cabinet 11, and the remaining four sub-guide rails 1121 have fixing parts 31 that are connected to the partition plate 113.

[0050] In one example, such as Figure 5 As shown, the sub-rail 1121 may also include one or more reinforcing ribs 33. The reinforcing ribs 33 are triangular plate-shaped structures, with their two right-angled sides connected to the fixing part 31 and the supporting part 32 respectively, and the reinforcing ribs 33 are perpendicular to the fixing part 31 and the supporting part 32. The reinforcing ribs 33 can increase the strength of the supporting part 32 in a direction perpendicular to the top plate 116 of the cabinet 11, preventing the supporting part 32 from bending under the pressure of the fan mounting bracket 13.

[0051] The fixing part 31 can be connected to the side wall of the fan housing cavity by means of welding, bonding, riveting or bolting. This embodiment of the utility model does not limit the connection method between the fixing part 31 and the side wall of the fan housing cavity.

[0052] The support part 32 can support the fan mounting bracket 13. The support part 32 can directly or indirectly contact the fan mounting bracket 13, thereby supporting the fan mounting bracket 13 in a direction perpendicular to the top plate 116 of the cabinet 11.

[0053] In this embodiment of the present invention, the sub-guide rail 1121 includes a fixed part 31 and a supporting part 32 connected vertically. The fixed part 31 can be connected to the side wall of the fan receiving cavity, and the supporting part 32 can support the fan mounting bracket 13, so that the fan mounting bracket 13 can slide along the extension direction of the sub-guide rail 1121 under the action of external force, thereby facilitating the removal or insertion of the fan mounting bracket 13 from the fan receiving cavity.

[0054] In one possible implementation, Figure 6 A schematic diagram of a fan cabinet 10 according to an embodiment of the present invention is shown, wherein the lower dashed circle is a partial enlarged view of the upper dashed circle. Figure 6 As shown, the sub-guide rail 1121, in addition to including the fixing part 31 and the support part 32, may also include a slide bar 34. The slide bar 34 is connected to the support part 32. When the guide rail 112 supports the fan mounting bracket 13, the slide bar 34 is located between the top surface of the support part 32 and the fan mounting bracket 13. Under the action of external force, the fan mounting bracket 13 can slide on the slide bar 34.

[0055] The slide bar 34 can be a strip-shaped structure, and it is fixed to the top surface of the support portion 32. When the fan mounting bracket 13 is placed on the guide rail 112, the slide bar 34 is located between the support portion 32 and the fan mounting bracket 13, and the support portion 32 supports the fan mounting bracket 13 through the slide bar 34. The coefficient of sliding friction between the slide bar 34 and the fan mounting bracket 13 is less than the coefficient of sliding friction between the support portion 32 and the fan mounting bracket 13.

[0056] In this embodiment of the invention, the slide bar 34 is fixed to the support portion 32 and is sandwiched between the support portion 32 and the fan mounting bracket 13. Under the action of external force, the fan mounting bracket 13 slides on the slide bar 34. Since the coefficient of sliding friction between the fan mounting bracket 13 and the slide bar 34 is small, a small external force can drive the fan mounting bracket 13 to slide on the slide bar 34, thereby reducing the labor intensity of pulling the fan mounting bracket 13 out of or into the fan receiving cavity.

[0057] In one possible implementation, such as Figure 7 The diagram shows the assembly of the sub-guide rail 1121. The slide bar 34 is provided with at least two countersunk holes 341, and the support part 32 is provided with screw holes 321 opposite to the countersunk holes 341. Screws passing through the countersunk holes 341 are connected to the corresponding screw holes 321 to fix the slide bar 34 and the support part 32. The heads of the screws used to connect the slide bar 34 and the support part 32 are lower than or flat with the contact surface between the slide bar 34 and the fan mounting bracket 13, that is, the heads of the screws are recessed in the countersunk holes 341 and do not protrude from the upper surface of the slide bar 34.

[0058] exist Figure 7 In the example shown, the slide bar 34 is provided with three countersunk holes 341, and the support part 32 is provided with three corresponding screw holes 321. In other embodiments, the slide bar 34 may be provided with two, four or more countersunk holes 341. This utility model embodiment does not limit the number of countersunk holes 341 provided on the slide bar 34.

[0059] In this embodiment of the invention, the slide bar 34 is provided with a countersunk hole 341, and the support part 32 is provided with a screw hole 321 corresponding to the countersunk hole 341. A screw passing through the countersunk hole 341 is connected to the corresponding screw hole 321 to fix the slide bar 34 and the support part 32, ensuring the stability of the connection between the slide bar 34 and the support part 32. The head of the screw used to connect the slide bar 34 and the support part 32 is lower than or flat with the contact surface between the slide bar 34 and the fan mounting bracket 13. When the fan mounting bracket 13 slides on the slide bar 34, the fan mounting bracket 13 will not contact the screw, so the screw will not hinder the sliding of the fan mounting bracket 13, ensuring that the fan mounting bracket 13 can slide smoothly on the slide bar 34.

[0060] In one possible implementation, Figure 8 This diagram illustrates the assembly of a fan mounting bracket 13 according to an embodiment of the present invention. Figure 7 and Figure 8 As shown, the support part 32 is provided with a first through hole 322, and a nut 323 is fixed to the bottom surface of the support part 32 at the position of the first through hole 322. The slide bar 34 is provided with a second through hole 342 corresponding to the first through hole 322. The fan mounting bracket 13 is provided with a third through hole 131. After the fan mounting bracket 13 slides on the slide bar 34 to the mounting position, bolts and nuts 323 are connected in sequence through the third through hole 131, the second through hole 342 and the first through hole 322, thus connecting the fan mounting bracket 13 to the support part 32.

[0061] exist Figure 7 and Figure 8 In the example shown, the support portion 32 has four first through holes 322, the slide bar 34 has four corresponding second through holes 342, the fan mounting bracket 13 has four corresponding third through holes 131, and the bottom surface of the support portion 32 is fixed with four corresponding nuts 323. In other embodiments, the support portion 32 may have two, three, or more first through holes 322. This embodiment of the present invention does not limit the number of first through holes 322 provided on the support portion 32.

[0062] In this embodiment of the utility model, when the fan mounting bracket 13 slides on the slide bar 34 to the mounting position, it can be connected to the support part 32 by bolts and nuts 323 that pass through the third through hole 131, the second through hole 342 and the first through hole 322 in sequence. This ensures that the fan mounting bracket 13 will not move relative to the cabinet 11 during the operation of the fan 20, ensuring the normal operation of the fan 20 and reducing the noise generated by vibration during the operation of the fan 20.

[0063] In one possible implementation, such as Figure 9The schematic diagram of the fan cabinet 10 shows that, along the direction perpendicular to the side wall of the fan housing cavity, the width of the slide bar 34 is smaller than the width of the support portion 32, and within the same fan housing cavity, the distance between two support portions 32 is smaller than the distance between two slide bars 34. When the support portion 32 supports the fan mounting bracket 13, the fan mounting bracket 13 contacts the slide bar 34. Because the width of the slide bar 34 is smaller than the width of the support portion 32, and the distance between two support portions 32 is smaller than the distance between two slide bars 34, there is a gap between the fan mounting bracket 13 and the support portion 32 with a height equal to the thickness of the slide bar 34.

[0064] like Figure 9 As shown, the fan cabinet 10 also includes at least one damper 14, which is disposed in the fan housing cavity and located between the air inlet and the fan mounting bracket 13. It should be noted that dampers 14 may be provided in each fan housing cavity, or only in some fan housing cavities; this embodiment of the present invention does not limit this.

[0065] Guide bars 141 are respectively provided on the top of the left and right sides of the damper 14, and the guide bars 141 are at least partially located in the gap between the fan mounting bracket 13 and the support part 32. The guide bars 141 allow the damper 14 to slide in a direction perpendicular to the rear side of the cabinet 11 under the action of external force.

[0066] The support part 32 supports the fan mounting bracket 13 through the slide bar 34. That is, the slide bar 34 is sandwiched between the support part 32 and the fan mounting bracket 13. Since the slide bar 34 has a certain thickness and the width of the slide bar 34 is less than the width of the support part 32, there is a strip gap between the support part 32 and the fan mounting bracket 13 with a thickness equal to the thickness of the slide bar 34. The guide bar 141 on the damper 14 can slide in this gap. At the same time, the support part 32 can support the damper 14 in a direction perpendicular to the top plate 116 of the cabinet 11.

[0067] Figure 10 A schematic diagram of a damper 14 according to an embodiment of the present invention is shown. Figure 10 As shown, the damper 14 includes at least one damper plate 142, which can rotate around an axis under the action of an external force, thereby adjusting the opening of the air inlet.

[0068] In this embodiment of the invention, the fan cabinet 10 includes a damper 14. The opening of the air inlet can be adjusted via the damper 14. For example, when the redundant fan is not in use, the air inlet corresponding to the redundant fan can be closed via the damper 14, ensuring the fan cabinet 10 has strong applicability. There is a gap between the support part 32 and the fan mounting bracket 13. The guide strip 141 on the damper 14 can slide within the gap, allowing the damper 14 to be disassembled and installed by pulling it out. This facilitates the removal of the damper 14 without removing the fan mounting bracket 13, improving the ease of maintenance of the fan cabinet 10.

[0069] In one possible implementation, Figure 11 A schematic diagram of the front panel 111 according to an embodiment of the present invention is shown, as follows: Figure 10 and Figure 11 As shown, a positioning pin 143 is provided on the front side wall of the damper 14, and a positioning component 117 is provided on the front side plate 111 of the cabinet 11, with a positioning hole 118 on the positioning component 117.

[0070] One or more locating pins 143 may be installed on the front side wall of the damper 14. Figure 10 In the example shown, two positioning pins 143 are provided on the front side wall of the damper 14. In other embodiments, one, three or more positioning pins 143 may be provided on the front side wall of the damper 14. This utility model embodiment does not limit the number of positioning pins 143 provided on the front side wall of the damper 14.

[0071] When two positioning pins 143 are provided on the front side plate of the damper 14, the two positioning pins 143 can be obtained by bending the steel strip into a U-shaped structure, such as... Figure 10 As shown, the middle plane of the U-shaped structure is fixedly connected to the front side plate of the damper 14, and the two ends of the U-shaped structure serve as two positioning pins 143.

[0072] Figure 11 The front panel 111 shown has 6 positioning elements 117, which are adapted to 3 dampers 14 with two positioning pins 143. In other embodiments, the front panel 111 can be provided with more or fewer positioning elements 117, as long as the number of positioning elements 117 on the front panel 111 is adapted to the number of dampers 14 and the number of positioning pins 143 provided on a single damper 14.

[0073] When the damper 14 slides to the installation position in a direction perpendicular to the rear side of the cabinet 11 under the application of external force, the positioning pin 143 is located in the positioning hole 118. Thus, in a direction perpendicular to the sliding direction of the damper 14, the cooperating positioning pin 143 and positioning hole 118 can restrict the relative position between the damper 14 and the cabinet 11.

[0074] In this embodiment of the invention, after the damper 14 moves to the installation position in a direction perpendicular to the rear side of the cabinet 11, the positioning pin 143 on the damper 14 is inserted into the positioning hole 118 on the front side plate 111. After the positioning pin 143 is fully inserted into the positioning hole 118, the damper 14 can no longer move towards the front side plate 111, thus achieving the purpose of limiting the damper 14 in the direction towards the front side plate 111. After the positioning pin 143 is inserted into the positioning hole 118, the cooperating positioning pin 143 and positioning hole 118 can limit the damper 14 and the cabinet 11 in a direction perpendicular to the front side plate 111, ensuring the stability of the damper 14 in the installation position.

[0075] In one possible implementation, such as Figure 12 The schematic diagram of the fan cabinet 10 shown shows that the fan cabinet 10 also includes a fixing plate 15. After the damper 14 slides to the installation position in a direction perpendicular to the rear side of the cabinet 11 under the action of external force, the fixing plate 15 can be connected to the fan mounting bracket 13 by bolts, and the fixing plate 15 can be connected to the front side plate of the damper 14 by bolts.

[0076] In this embodiment of the utility model, when the damper 14 is in the installation position, the fixing plate 15 can be connected to the fan mounting bracket 13 and the front side plate of the damper 14 respectively. The fixing plate 15 can restrict the damper 14 from moving away from the front side plate 111 of the cabinet 11. The fixing plate 15 and the corresponding positioning pin 143 and positioning hole 118 can limit the damper 14 in three dimensions to ensure the stability of the position of the damper 14 during the operation of the fan 20.

[0077] Figure 13 A schematic diagram of a heat dissipation system according to an embodiment of the present invention is shown. Figure 13 As shown, the heat dissipation system 100 includes a heat source cabinet 40, a heat exchange cabinet 50, and a fan cabinet 10 in any of the above embodiments.

[0078] The heat source cabinet 40 contains heat source equipment that requires heat dissipation, such as power units, transformers, frequency converters, etc. The heat exchange cabinet 50 contains a heat exchanger, which can be an air-water cooled heat exchanger.

[0079] The heat exchange cabinet 50 and the fan cabinet 10 are located at the rear of the heat source cabinet 40, and the fan cabinet 10 is located at the top of the heat exchange cabinet 50.

[0080] One or more fans 20 are installed in the fan cabinet 10.

[0081] In this embodiment of the invention, driven by the fan 20, the low-temperature air flowing through the heat source equipment in the heat source cabinet 40 absorbs heat and generates high-temperature air. This high-temperature air enters the heat exchange cabinet 50 from the bottom of the heat source cabinet 40. Inside the heat exchange cabinet 50, the high-temperature air exchanges heat with the heat exchange equipment and generates low-temperature air. This low-temperature air enters the fan cabinet 10 from the top of the heat exchange cabinet 50. The fan 20 drives the low-temperature air in the fan cabinet 10 to enter the heat source cabinet 40 from the rear, forming a closed-loop cooling system. Without needing to remove the fan cabinet 10 from the top of the heat exchange cabinet 50, the fan 20 requiring maintenance can be pulled out of the fan cabinet 10, thus saving on maintenance efficiency. Since the air flowing through the fan 20 is low-temperature, the impact of high-temperature air on the service life of the fan 20 is eliminated, thereby extending the service life of the fan 20.

[0082] In one possible implementation, a sealing strip is provided at the connection between the cover plate 12 and the cabinet 11 in the fan cabinet 10, and sealing strips are also provided at the connection between the fan cabinet 10 and the heat source cabinet 40 and the heat exchange cabinet 50. The sealing strips can prevent dust, moisture and other substances from entering the fan cabinet 10, so that the fan cabinet 10 has high protection and can meet the IP55 protection level requirements.

[0083] It should be noted that the heat dissipation system 100 provided in this embodiment is a specific application of the fan cabinet 10 in the foregoing embodiment. For details and beneficial effects, please refer to the description in the foregoing fan cabinet 10 embodiment, which will not be repeated here.

The execution order of each step is not fixed and can be adjusted as required. The system structure described in the above embodiments can be a physical structure or a logical structure.
