Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical cabinets, in particular to a fan mounting structure and an electrical cabinet. BACKGROUND

[0002] In existing electrical cabinets such as UPS cabinets, there are electrical devices such as transformers that generate heat during use. Therefore, a fan needs to be provided in the electrical cabinet to form a heat dissipation channel that connects the heat-generating electrical devices and the fan. The fan can blow the heat generated by the heat-generating electrical devices out of the cabinet to reduce the temperature inside the electrical cabinet and prevent the electrical devices from overheating. The existing fan is generally installed on a base plate in an integrated ventilation module by screwing, and then the base plate of the ventilation module is directly installed on the cabinet body by screwing. The ventilation module is generally installed on the outer shell of the cabinet, such as the rear outer shell or the top outer shell of the cabinet. The outer shell of the cabinet is provided with through holes that match the size of the ventilation module. After the ventilation module is inserted into the through holes, it is fixed by screwing.

[0003] The existing fan mounting method requires that a corresponding number of through holes be provided on the outer shell of the cabinet according to the predetermined number of fans. However, the number of fans required to be provided on different electrical cabinets may be different, or the heat dissipation of the electrical devices installed in the same size shell may be different, which will result in the number of through holes provided on the outer shell of the electrical cabinet needing to be adjusted according to the actual situation, and the through holes cannot be modified after being provided. This results in a decrease in production efficiency and an increase in the likelihood of errors in the production of the cabinet outer shell. SUMMARY

[0004] The present application aims to overcome the above-mentioned defects or problems in the background art and provide a fan mounting structure and an electrical cabinet. The outer shell of the electrical cabinet can only be provided with one through hole for mounting the installation base of the fan mounting structure. The number and position of the ventilation modules can be adjusted by cooperating with the installation base, so that the electrical cabinet does not need to be provided with different numbers of through holes according to the actual situation, thereby improving the production efficiency of the cabinet outer shell.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A fan mounting structure for fixing and installing on an electrical cabinet to form a duct in communication with the interior of the electrical cabinet in cooperation with the electrical cabinet, comprising: a mounting base fixedly installed on the electrical cabinet and provided with an assembly slot in communication with the interior and exterior of the electrical cabinet and extending in a first direction; and a plurality of duct members adapted to be installed in the assembly slot and closely connected to each other in the first direction to form the duct in cooperation with the electrical cabinet; wherein the two sides of the assembly slot parallel to the first direction are provided with sliding grooves, and at least one end of the first direction is provided with an opening for the duct members to enter the sliding grooves; the duct members are adapted to be detachably fixed with the mounting base at the opening, and at least one of the duct members is configured to include a fan adapted to form an air inlet end and / or an air outlet end of the duct.

[0007] Further, the duct member including the fan is defined as a ventilation module, and the duct member not including the fan is defined as a blocking module; the blocking module is adapted to cover the area in the assembly slot not occupied by the ventilation module; the size of the assembly slot in the first direction is adapted to N ventilation modules and Y blocking modules, where N and Y are both integers greater than 1.

[0008] Further, the ventilation module further includes a fan fixing base plate, the size of the fan fixing base plate in a second direction perpendicular to the first direction is adapted to the distance of the sliding grooves along the two sides of the assembly slot to form a sliding fit with the sliding grooves; the fan is fixedly installed on the fan fixing base plate.

[0009] Further, the ventilation module further includes a fan mesh cover, the fan mesh cover is fixedly connected to the fan fixing base plate and covers the fan.

[0010] Further, the mounting base includes a mounting base plate and a sliding groove plate; the mounting base plate is fixedly connected to the electrical cabinet and is provided with the assembly slot thereon; the sliding groove plate is fixedly connected to one side of the mounting base plate facing the interior of the electrical cabinet or the exterior of the electrical cabinet, and cooperates with the mounting base plate to form the sliding groove.

[0011] Further, the sliding groove plate is fixedly installed on the side of the mounting base plate facing the interior of the electrical cabinet; the mounting base plate is provided with the opening in communication with the sliding groove at one end of the assembly slot, and the opening is located on the side of the mounting base plate facing the exterior of the electrical cabinet.

[0012] Further, the blocking module is a plate-shaped member, the size of the blocking module in the second direction is adapted to the distance of the sliding grooves along the two sides of the assembly slot to form a sliding fit with the sliding grooves.

[0013] Further, each of the fan fixing base plate and the blocking module is provided with a mounting through hole; the mounting through hole is adapted for a bolt to penetrate through so that the ventilation module and the blocking module are detachably fixed to the mounting base plate.

[0014] In addition, the application further provides an electrical cabinet comprising a cabinet body and a plurality of electrical devices located inside the cabinet body, which adopts the fan mounting structure according to any one of the above; the ventilation module and / or the blocking module are mounted on the cabinet body through the mounting base.

[0015] Further, the electrical devices comprise a plurality of UPS modules and a transformer connected to the UPS modules; the mounting base is arranged close to the transformer on the cabinet body.

[0016] From the above description of the application, the application has the following beneficial effects compared with the prior art:

[0017] 1. The fan mounting structure comprises a mounting base and a plurality of air duct components; the mounting base can be fixedly mounted on an electrical cabinet; since the size of the mounting base corresponds to the type of the electrical cabinet, the size of the through hole on the electrical cabinet for cooperating with the mounting base can be fixed, and only a through hole corresponding to the number of the mounting base needs to be opened on the electrical cabinet; the mounting base can be installed at various positions of the electrical cabinet, such as the back or top of the electrical cabinet, etc.

[0018] The mounting base is provided with an assembly groove, which is in communication with the inside and outside of the electrical cabinet, so the assembly groove is through; meanwhile, a sliding groove is arranged on the assembly groove; the air duct components can slide along the sliding groove to a position abutting against the end of the assembly groove; an opening is further arranged at the end of the assembly groove; the air duct components can enter the sliding groove from the opening; therefore, during installation, the air duct components can be sent into the sliding groove from the opening, then the air duct components are slid in the sliding groove, and finally the air duct components at the opening are detachably fixed on the mounting base, thereby realizing the installation of the plurality of air duct components on the mounting base.

[0019] If the air duct component is configured to include a fan, it can form an air inlet end or an air outlet end of the air duct; if the air duct component is configured not to include a fan, the air duct component can serve as a wall surface surrounding the air duct; through the combination of the air duct component including a fan and the air duct component not including a fan, the air duct formed on the electrical cabinet can be adjusted so that the air outlet or air inlet of the fan can be more adapted to the actual needs.

[0020] The air duct components are closely connected to each other, which can avoid the vibration of the air duct component including a fan when the fan is working.

[0021] Through the mounting structure, the air duct component only needs to be arranged and positioned in the assembly slot during installation, and then the air duct component at the opening is locked, without the need to bolt each air duct component, so that the working space of workers during installation is larger, and interference with the lines in the electrical cabinet due to bolt locking of the air duct component during installation can be avoided. In addition, the shell of the electrical cabinet does not need to be provided with a corresponding number of through holes according to the number of air duct components, but only needs to be provided with a through hole for fixing the mounting base at a preset position according to the installation needs, thereby effectively improving the production efficiency of the shell of the electrical cabinet.

[0022] 2、The ventilation module can dissipate heat inside the electrical cabinet through the fan thereon, and the number of ventilation modules can be adjusted according to actual needs, but the maximum number is matched with the size of the assembly slot. For example, when the size of the assembly slot can only allow three ventilation modules to be installed, the electrical cabinet can at most install three ventilation modules at this position, and the size of the assembly slot and the size of the ventilation module are in a multiple relationship, that is, when the maximum number of ventilation modules is installed, the assembly slot will be filled with the ventilation modules, and the ventilation modules cannot move in the assembly slot to prevent the ventilation modules from vibrating greatly during work due to loosening. The blocking module plays a role in adjusting the number of ventilation modules, and it can replace one or more ventilation modules installed in the assembly slot. After the blocking module is installed in the assembly slot, it can cover the area of the assembly slot, thereby cooperating with the electrical cabinet to form a new air duct, avoiding damage to the air duct in the electrical cabinet, and avoiding vibration of the fan during work through close cooperation with the assembly slot.

[0023] 3、The fan fixing base plate on the ventilation module is used to fix and install the fan and can be slidably installed in the assembly slot.

[0024] 4、The fan mesh cover can prevent external debris from entering the electrical cabinet.

[0025] 5、The installation base plate is used to be fixed with the electrical cabinet, and the sliding groove plate is used to cooperate with the installation base plate to form a sliding groove.

[0026] 6、The sliding groove plate is arranged at the back of the installation base plate, which can avoid disordered appearance of the installation base.

[0027] 7、The blocking module is a plate-shaped component, which can be used to cover the assembly slot and avoid damage to the air duct in the electrical cabinet.

[0028] 8、The fan fixing base plate and the blocking module are each provided with a mounting through hole, and each fan module and blocking module can be installed at the opening of the installation base.

[0029] 9. The electrical cabinet has the fan mounting structure, so that it only needs to open a through hole for fixing the mounting base according to the installation needs, effectively improves the production efficiency of the electrical cabinet shell, and adjusts the combination of the air duct member according to the actual needs, so that the ventilation effect of the air duct can match the heat generated by the electrical cabinet, and the problems of waste and delayed heat dissipation are avoided.

[0030] 10. The electrical cabinet can be a UPS cabinet, and the ventilation module in the fan mounting structure can be arranged close to the transformer to achieve effective heat dissipation. BRIEF DESCRIPTION OF DRAWINGS

[0046] As an embodiment, the electrical cabinet can be a UPS cabinet, and the electrical devices installed inside can include a plurality of UPS modules and a transformer connected with the UPS modules, wherein the transformer generates a large amount of heat in this type of electrical cabinet.

[0047] The electrical cabinet mainly comprises a cabinet body 10 and a plurality of electrical devices, wherein the cabinet body 10 is internally formed with a chamber for mounting the electrical devices, as an embodiment, the cabinet body 10 can also be formed with a plurality of chambers for mounting different types of electrical devices by partitions, for example, the lower side of the cabinet body 10 can be a separate chamber for mounting a transformer, and above the separate chamber is another chamber for placing a UPS module, the cabinet body 10 can be closed by a cabinet door, and the fan mounting structure described above can be mounted on the cabinet door or the wall shell forming the chamber by the partition.

[0048] The fan mounting structure provided by the embodiment is used for fixing and mounting on the electrical cabinet to cooperate with the electrical cabinet to form an air duct communicating with the inside of the electrical cabinet, which mainly comprises a mounting base 20 and a plurality of air duct members.

[0049] Referring to Figures 2 to 5 , the mounting base 20 is fixedly mounted on the electrical cabinet, and a fitting groove 23 extending along a first direction and communicating with the inside and outside of the electrical cabinet is arranged on the mounting base 20; the air duct members 30 are adapted to be mounted in the fitting groove 23 and closely connected to each other in the first direction to cooperate with the electrical cabinet to form an air duct; wherein the two sides of the fitting groove 23 parallel to the first direction are provided with sliding grooves 232, and at least one end of the first direction is provided with an opening 231 for the air duct members to enter the sliding grooves 232; the air duct members 30 are adapted to be detachably fixed with the mounting base 20 at the opening 231, and at least one of the air duct members 30 is configured to include a fan 32, and the fan 32 is adapted to form an air inlet end and / or an air outlet end of the air duct.

[0050] In the embodiment, the air duct members 30 are divided into ventilation modules and blocking modules, wherein the ventilation module is defined as the air duct member 30 including a fan, and the blocking module is defined as the air duct member 30 not including a fan; wherein the size of the fitting groove 23 in the first direction is adapted to N ventilation modules and Y blocking modules, and N and Y are both integers greater than 1.

[0051] Specifically, the mounting base 20 comprises a mounting base plate 21 and a sliding groove plate 22, the mounting base plate 21 is fixedly connected to the electrical cabinet and is provided with the fitting groove 23 described above, and the sliding groove plate 22 is fixedly connected to one side of the mounting base plate 21 facing the inside or outside of the electrical cabinet, and cooperates with the mounting base plate 21 to form the sliding groove 232. In the embodiment, the sliding groove plate 22 is fixedly mounted on the side of the mounting base plate 21 facing the inside of the electrical cabinet, and the mounting base plate 21 is provided with the opening 231 described above communicating with the sliding groove 232 at one end of the fitting groove 23, and the opening 231 is located on the side of the mounting base plate 21 facing the outside of the electrical cabinet.

[0052] Specifically referring to Figures 2 to 5The mounting base plate 21 in the mounting base 20 can be regarded as a rectangular plate-shaped member with a hollowed middle part. Two fixed ribs 11 extending in the vertical direction and symmetrically positioned are arranged on the cabinet body 10. The two ends of the mounting base plate 21 in the length direction are fixed to the two fixed ribs 11 by bolts, so that the mounting base plate 21 is installed on the cabinet body 10 in a vertical manner. After the mounting base plate 21 is fixed to the cabinet body 10, the length direction of the mounting base plate 21 is the first direction, and the vertical direction is the second direction. In the embodiment, the mounting base plate 21 is installed below the cabinet body 10. In an electrical cabinet for storing UPS modules, the position can be the position for placing a transformer. Fixing the mounting base plate 21 at this position can allow the subsequent ventilation module to dissipate heat for the transformer.

[0053] The number of the sliding groove plates 22 is two, which are arranged on the upper and lower sides of the mounting base plate 21 in the width direction, i.e., the two sides of the mounting base plate 21 parallel to the first direction. In the embodiment, the sliding groove plate 22 is arranged on the side of the mounting base plate 21 facing the inside of the cabinet. The sliding groove plate 22 can be regarded as a long strip-shaped plate-shaped member, the length of which is slightly smaller than that of the mounting base plate 21 and is substantially consistent with the length of the assembly groove 23. The sliding groove plate 22 can be fixed to the mounting base plate 21 by bolts. The sliding groove plate 22 is formed with a stepped structure bent towards the inside of the cabinet, so that the bent part of the stepped structure can form a gap with the mounting base plate 21 when the sliding groove plate 22 is fixed to the mounting base plate 21. The gap is the sliding groove 232. In addition, the mounting base plate 21 is provided with a blocking wall 211 at both ends of the assembly groove 23 in the first direction. The blocking wall 211 can cooperate with the sliding groove 232 to close the two ends of the sliding groove 232.

[0054] In addition, an opening 231 communicating with the sliding groove 232 is arranged on the side of the mounting base plate 21 facing the outside of the cabinet. The opening 231 can be regarded as a gap formed in the part of the mounting base plate 21 as a side wall of the sliding groove 232. The length of the gap in the first direction is adapted to the size of the ventilation module and the blocking module. Through the opening 231, the ventilation module and the blocking module can enter the sliding groove 232. It should be noted that the direction of the opening 231 is towards the outside of the cabinet along a direction perpendicular to the plane of the mounting base plate 21, so that the ventilation module and the blocking module can enter the sliding groove 232 from the front of the mounting base plate 21.

[0055] It should be noted that the sliding groove plate 22 is provided with screw holes at the positions corresponding to the opening 231. The ventilation module or the blocking module positioned at the opening 231 can be fixed and installed on the mounting base plate 21 by the screw holes in a bolt fastening manner.

[0056] The ventilation module comprises a fan fixing base plate 31, a fan 32 and a fan mesh cover 33. The fan fixing base plate 31 is adapted in size in the second direction perpendicular to the first direction to the distance between the sliding grooves 232 on the two sides of the assembly groove 23 to form a sliding fit with the sliding grooves 232. The fan 32 and the fan mesh cover 33 are fixedly installed on the fan fixing base plate 31, and the fan mesh cover 33 is fixedly connected to the fan fixing base plate 31 and covers the air outlet end of the fan 32.

[0057] The blocking module is a plate-shaped member, which is adapted in size in the second direction to the distance between the sliding grooves 232 on the two sides of the assembly groove 23 to form a sliding fit with the sliding grooves 232.

[0058] Specifically, referring to Figure 2 and Figure 3 , the fan fixing base plate 31 in the ventilation module is a square plate-shaped member, which is adapted in size to the distance between the two sliding grooves 232 on the mounting base 20. Through the opening 231 on the mounting base 20, the fan fixing base plate 31 can enter the sliding groove 232 and form a sliding fit with the sliding groove 232. The fan 32 is fixedly installed in the middle of the fan fixing base plate 31 by bolts, and the fan mesh cover 33 is arranged at the air outlet end of the fan 32 to prevent sundries from falling onto the fan 32 or entering the cabinet interior.

[0059] The blocking module is a plate-shaped member with the same size as the fan fixing base plate 31, which can also form a sliding fit with the sliding groove 232, so as to enter the sliding groove 232 through the opening 231 on the mounting base 20.

[0060] Mounting through holes are arranged on the fan fixing base plate 31 and the blocking module, which are adapted to be penetrated by bolts to detachably fix the ventilation module and the blocking module to the mounting base 21.

[0061] It should be noted that, in order to prevent the ventilation module from vibrating during work after being installed on the mounting base 20, the size of the assembly groove 23 in the first direction should be adapted to the size of the ventilation module and the blocking module. For example, in the present embodiment, the size of the assembly groove 23 in the first direction can accommodate three ventilation modules with the same size, and after the three ventilation modules are installed in place, each ventilation module is tightly fitted with the assembly groove 23, and the ventilation module cannot slide in the first direction. Similarly, since the blocking module has the same size as the ventilation module, the ventilation module can be replaced by the blocking module, and the same limiting effect can still be achieved. For example, in the above example, the ventilation module in the middle is replaced by the blocking module, and the assembly groove 23 is still tightly fitted with the three modules in the groove.

[0062] Of course, the size of the blocking module can also be smaller than that of the ventilation module, but it should be noted that the size of the blocking module should be in a multiple relationship with the size of the ventilation module, for example, the size of two blocking modules can match the size of one ventilation module, that is, the length of the two blocking modules is consistent with the side length of the ventilation module, and the width of the two blocking modules is half of the side length of the ventilation module.

[0063] Wherein, the ventilation module is replaced by the blocking module, which can be adapted to the electrical cabinet with smaller heat generation, and reduce the occupation of electric energy, and the blocking module can be part of the cabinet body 10, forming a wind channel connected with the ventilation module, so as to ensure that the heat in the cabinet can be effectively sent out along the wind channel.

[0064] Specific installation, refer to Figure 6 The first ventilation module is installed from the opening 231 of the mounting base 20, and then slid to the right end, and then the second and third ventilation modules are installed in the same way, and finally the ventilation module at the opening 231 is fixed on the mounting base 20 by bolt fastening, so that the installation of the ventilation module is completed.

[0065] When replacement is needed, the leftmost ventilation module is removed, the ventilation module to be replaced is removed, and then the new ventilation module or blocking module is installed in the above-mentioned process to the predetermined position, and finally the ventilation module or blocking module at the opening 231 is fixed on the mounting base 20.

[0066] The present application provides a fan mounting structure and an electrical cabinet, the fan mounting structure comprises a mounting base 20, a plurality of ventilation modules and a plurality of blocking modules, the mounting base 20 can be fixedly installed on the electrical cabinet, since the size of the mounting base 20 corresponds to the type of the electrical cabinet, the size of the through hole on the electrical cabinet for cooperating with the mounting base 20 can be fixed, and only the through hole corresponding to the number of the mounting base 20 needs to be opened on the electrical cabinet, the mounting base 20 can be installed at various positions of the electrical cabinet, such as the back or top of the electrical cabinet, etc.

[0067] The mounting base 20 is provided with an assembly groove 23 which communicates the inside and outside of the electrical cabinet, so the assembly groove 23 is through; meanwhile, the assembly groove 23 is provided with a sliding groove 232, the ventilation module and the blocking module can slide to the position of abutting against the end of the assembly groove 23 along the sliding groove 232, and the assembly groove 23 is also provided with an opening 231, the ventilation module and the blocking module can enter the sliding groove 232 from the opening 231, so the ventilation module and the blocking module can be sent into the sliding groove 232 from the opening 231 during installation, then the ventilation module and the blocking module are slid in the sliding groove 232, and finally the ventilation module or the blocking module at the opening 231 is detachably fixed on the mounting base 20, so as to realize the installation of the ventilation module or the blocking module;

[0068] The ventilation module can dissipate heat in the electrical cabinet through the fan 32 thereon, and the number of the ventilation module can be adjusted according to actual needs, but the maximum number is matched with the size of the assembly groove 23, for example, when the size of the assembly groove 23 can only allow three ventilation modules to be installed, the electrical cabinet can only install three ventilation modules at most at this position, and the size of the assembly groove 23 and the size of the ventilation module are in a multiple relationship, that is, when the maximum number of ventilation modules is installed in the assembly groove 23, the assembly groove 23 will be filled with the ventilation modules, and the ventilation modules cannot move in the assembly groove 23, so as to prevent the ventilation modules from vibrating greatly during work due to loosening in the assembly groove 23;

[0069] In addition, the blocking module plays a role in adjusting the number of ventilation modules, which can replace one or several ventilation modules installed in the assembly groove 23, and after the blocking module is installed in the assembly groove 23, it can cover the area of the assembly groove 23, thereby cooperating with the electrical cabinet to form a new air duct, avoiding the air duct in the electrical cabinet from being damaged, and also avoiding the vibration of the fan 32 during work through the close cooperation with the assembly groove 23;

[0070] Through the installation structure, the air duct component 30 only needs to be slid and arranged in the assembly groove 23 during installation, and then the air duct component 30 at the opening 231 is locked, without the need to bolt each air duct component 30, so that the working space of the worker during installation is larger, and interference with the lines in the electrical cabinet caused by the bolted air duct component 30 during installation can be avoided; in addition, the shell of the electrical cabinet also does not need to be provided with a corresponding number of through holes according to the number of the air duct component 30, but only needs to be provided with a through hole for fixing the mounting base 20 at a preset position according to the installation needs, so as to effectively improve the production efficiency of the shell of the electrical cabinet.
