Description

Technical Field

[0001] This utility model belongs to the field of IGBT cooling technology, specifically relating to an immersion IGBT module mounting structure. Background Technology

[0002] IGBT modules are modular packaged products of insulated-gate bipolar transistors, combining the advantages of MOSFETs and bipolar transistors, and are widely used in the power electronics field. IGBT modules generate a significant amount of heat during operation. To ensure stable operation, the current method involves immersing the IGBT modules in cooling fluid to improve heat dissipation. The common approach is to install the IGBT modules in a coolant-filled enclosure, allowing the coolant to directly cool the IGBTs. However, most enclosures used for mounting IGBT modules are currently bolted directly to the inside of a cabinet. This makes disassembly and maintenance difficult due to the limited internal space, hindering the convenience of future IGBT module maintenance. Utility Model Content

[0003] This utility model provides an immersion IGBT module mounting structure, which aims to solve the problem that the existing IGBT module mounting methods are inconvenient to install and remove.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an immersion IGBT module mounting structure, comprising:

[0005] Support beams are installed inside the cabinet.

[0006] The module box is installed on the support beam;

[0007] Multiple guide members are installed on the support beam, and the multiple guide members are paired up to form guide grooves for installing the module box;

[0008] A limiting component, installed inside the cabinet, is used to limit the position of the module box as it slides into the cabinet.

[0009] A fixing component is used to fix the module box to the support beam.

[0010] In one possible implementation, the limiting component includes:

[0011] The top beam is installed inside the cabinet and located above the support beam. The top beam and the support beam together form an installation space for accommodating the module box.

[0012] A limiting component is installed on the top of the module box, and the limiting component can abut against the side wall of the top beam to limit the sliding of the module box into the cabinet.

[0013] In one possible implementation, the limiting member is provided with mounting holes for fixing to the top beam.

[0014] In one possible implementation, there are multiple top beams, with top beams provided on both sides of the module box, and the top beams are detachably connected to the inside of the cabinet.

[0015] In one possible implementation, the limiting member is also equipped with a baffle for blocking the module box at the inlet of the guide groove.

[0016] In one possible implementation, a support member for supporting the baffle is also installed at the bottom of the module box, and the support member is detachably installed on the module box.

[0017] In one possible implementation, the fixing component includes:

The support beam 2 is installed inside the cabinet 1; the module box 3 is installed on the support beam 2; multiple guide members 4 are installed on the support beam 2, and the multiple guide members 4 are paired to form guide grooves for installing the module box 3; the limiting component 5 is installed inside the cabinet 1 to limit the position of the module box 3 as it slides into the cabinet 1; the fixing component is used to fix the module box 3 to the support beam 2.

[0031] The immersion IGBT module installation structure provided in this embodiment, compared with the prior art, features multiple support beams 2 installed inside the cabinet 1, with the support beams 2 arranged parallel and spaced apart. Guide members 4 are overlapped between the support beams 2, and guide plates are bent upwards on the guide members 4. The guide plates on two guide members 4 form a guide groove for installing the module box 3. The cabinet 1 also has a limiting component 5 for limiting the module box 3 after it is installed in place, and a fixing component for fixing the module box 3 to the support beams 2. In this application, the IGBT module is installed inside the module box 3. When installing the IGBT module into the cabinet 1, it is pushed and slid into the cabinet 1, and the limiting component 5 is used to limit and position the module box 3, which is then fixed by the fixing component. For later maintenance, the module box 3 can be pulled out from the cabinet 1 as a whole, which is convenient and simple to use, facilitating disassembly and installation during maintenance.

[0032] Specifically, in this embodiment, the IGBT module is installed inside the module box 3, and a coolant for cooling the IGBT module is provided inside the module box 3.

[0033] In some embodiments, the limiting component 5 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The limiting component 5 includes a top beam 51 and a limiting member 52. The top beam 51 is installed inside the cabinet 1 and above the support beam 2. The top beam 51 and the support beam 2 form an installation space for accommodating the module box 3. The limiting member 52 is installed on the top of the module box 3 and can abut against the side wall of the top beam 51 to limit the sliding of the module box 3 into the cabinet 1. The top beam 51 is also installed above the support beam 2. The module box 3 is located between the support beam 2 and the top beam 51. The limiting member 52 includes two mutually perpendicular wing plates. One wing plate is used to fix to the top of the module box 3, and the other wing plate is bent upward. When the module box 3 slides into the cabinet 1, the upwardly bent wing plate can abut against the side of the top beam 51, thereby positioning the module box 3.

[0034] Specifically, in this embodiment, both the top beam 51 and the support beam 2 are fixed to the cabinet 1 with bolts. Furthermore, there are multiple top beams 51 and support beams 2, and each adjacent top beam 51 and adjacent support beam 2 is connected by a reinforcing beam to strengthen the connection.

[0035] In some embodiments, the limiting member 52 may be adopted as follows: Figure 2 The structure shown. See also Figure 2The limiting member 52 is provided with mounting holes for fixing to the top beam 51. The mounting holes are elongated holes, and rivet nuts are fixedly installed on the side wall of the top beam 51, so that the limiting member 52 can be fixedly installed to the top beam 51 with bolts. After the limiting member 52 abuts against the side of the top beam 51, it can also be fixed with bolts, thereby improving the stability of the installation position of the module box 3.

[0036] In some embodiments, the top beam 51 may be as follows: Figure 2 The structure shown. See also Figure 2 There are multiple top beams 51, with one on each side of the module box 3. The top beams 51 are detachably connected to the inside of the cabinet 1. Multiple module boxes 3 are arranged at intervals along the length of the cabinet 1. Multiple top beams 51 are also arranged at intervals along the direction of the module boxes 3. The same top beam 51 located between two module boxes 3 is positioned between adjacent module boxes 3. One end of the edge top beam 51 is installed on the inner wall of the cabinet 1, and the other end is located above the module box 3. Piping and detection elements are installed on the top of the module box 3. The gap between two top beams 51 allows for easier installation and removal of the module box 3 during disassembly or installation.

[0037] Specifically, in this embodiment, a connecting rod is installed on the top of the top beam 51. One end of the connecting rod is fixedly installed on the top beam 51 by bolts, and the other end of the connecting rod is fixedly installed on the top of the cabinet 1, thereby realizing the connection between the top beam 51 and the cabinet 1.

[0038] In some embodiments, the limiting member 52 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 3 , Figure 4 The limiting member 52 is also equipped with a baffle 31 for blocking the module box 3 at the inlet of the guide groove. A mounting plate for mounting the baffle 31 is bent outwards at the top of the limiting member 52. The top of the baffle 31 has a bent portion for overlapping the mounting plate, and the bent portion is bolted to the mounting plate, thus allowing the baffle 31 to be installed on the limiting member 52. The bottom of the baffle 31 is detachably mounted to the module box 3 by bolts. The baffle 31 provides a certain degree of protection for the module box 3.

[0039] In some embodiments, the module box 3 described above can be adopted as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4The bottom of the module box 3 is also equipped with a support member 32 for supporting the baffle 31. The support member 32 is detachably installed on the module box 3. A side plate for mounting the support member 32 is fixedly installed on the side of the module box 3. The support member 32 is bolted to the side plate and extends outward to connect to the baffle 31. By setting the support member 32, the lower end of the baffle 31 can be fixed to the module box 3, and the baffle 31 and the module box 3 are spaced apart to ensure the stability of the baffle 31 installation.

[0040] Specifically, in this embodiment, the support member 32 is integrally bent and formed, and the baffle 31 is fixedly installed on the support member 32. A connector for connecting to the limiting member 52 is also fixedly installed on the top of the baffle 31, and the connector is detachably installed on the limiting member 52.

[0041] In some embodiments, the aforementioned fixing component may employ, for example... Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4 The fixing assembly includes a fixing member 6. The fixing member 6 includes a fixing plate 61 for fixing to the support beam 2 and a connecting plate 62 for fixing to the module box 3. The fixing member 6 is integrally bent and formed. The connecting plate 62 and the fixing plate 61 are arranged perpendicular to each other. The connecting plate 62 is fixedly installed on the outside of the module box 3 by bolts, and the fixing plate 61 is fixedly installed on the support beam 2 by bolts. A reinforcing plate is also provided between the connecting plate 62 and the fixing plate 61 to enhance the positional stability of the connecting plate 62 and the fixing plate 61. Fixing members 6 are installed on both sides of the module box 3, thereby fixing the module box 3 to the support beam 2.

[0042] Specifically, in this embodiment, a limiting plate is installed on the support beam 2 on one side of the cabinet 1 away from the guide groove inlet. The limiting plate is bent upward on the support beam 2 to limit the movement of the module box 3 inside the cabinet 1.

[0043] In some embodiments, the module box 3 described above can be adopted as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4 Side support ribs 33 are fixedly installed on both sides of the module box 3, and the connecting plate 62 is detachably installed on the side support ribs 33. Side support ribs 33 are provided on both sides of the module box 3 along its width direction, and the length direction of the side support ribs 33 is arranged vertically. Two side support ribs 33 are provided on each side of the module box 3, and the two side support ribs 33 are arranged parallel to each other at intervals. A reinforcing rib is also connected between the two side support ribs 33, and a handle is installed on the reinforcing rib to facilitate pulling the module box 3. This enhances the overall strength of the module box 3 and facilitates its movement.

[0044] Preferably, in this embodiment, a rivet nut is installed on the side support rib 33, and a bolt through hole corresponding to the rivet nut is provided on the connecting plate 62 of the fastener 6. Thus, the fastener 6 can be fixedly connected to the module box 3 by bolts, which can reduce damage to the module box 3. At the same time, the connection between the fastener 6 and the module box 3 can be enhanced by connecting with the side support rib 33.

[0045] In some embodiments, the module box 3 described above can be adopted as follows: Figure 1 , Figure 5 The structure shown. See also... Figure 1 , Figure 5 A liquid connector is located on the side of module box 3 near the inlet of the guide channel. A liquid receiving tray 7 is also installed on the support beam 2. When module box 3 is installed on support beam 2, the liquid receiving tray 7 is located below the liquid connector. Liquid receiving chambers are installed directly below multiple support beams 2, and the bottom of the liquid receiving chambers is connected to a drain pipe. The number of liquid receiving trays 7 corresponds one-to-one with the number of module boxes 3. Multiple liquid receiving trays 7 are located above the liquid receiving chambers, and each liquid receiving tray 7 is equipped with a drain port for discharging liquid into the liquid receiving chamber. When module box 3 is installed on support beam 2, the liquid connector on module box 3 is located directly above the liquid receiving tray 7. This prevents liquid from flowing into the cabinet 1 and damaging other electrical components during connection with other pipelines, thus ensuring safety during the assembly and disassembly of module box 3.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
