DETAILED DESCRIPTION

[0050] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0051] This application discloses a power module 100 .

[0052] The power module 100 according to an embodiment of the present application is described below with reference to FIG. 1 to FIG. 12 .

[0053] In some embodiments, as shown in FIG. 1 to FIG. 6 , the power module 100 includes a base 110 and a plurality of module bodies 120 .

[0054] The base 110 may be provided with a mounting position and a first sliding structure 111 for slidingly cooperating with the cabinet 200. There may be multiple mounting positions, and the mounting positions may be provided with a second sliding structure 112. The module body 120 may be provided with a third sliding structure 122. The third sliding structure 122 may be slidably cooperating with the second sliding structure 112, and multiple module bodies 120 may be suitable for being installed in multiple mounting positions through the third sliding structure 122.

[0055] The plurality may be 2 or more. For example, in some embodiments, as shown in FIG. 1 and FIG. 2 , there are 3 module bodies 120 , and correspondingly, there are also 3 mounting positions.

[0056] The first sliding structure 111 may include but is not limited to a slider, a skateboard, or a pulley. For example, in some embodiments, as shown in FIG. 1 to FIG. 6 , the first sliding structure 111 is a skateboard.

[0057] The third sliding structure 122 may include but is not limited to a slider, a slide plate or a pulley. For example, in some embodiments, as shown in FIG. 1 to FIG. 10 , the third sliding structure 122 is a slide plate, and correspondingly, the second sliding structure 112 is a slide rail.

[0058] In actual implementation, as shown in Figures 1 to 6, when multiple module bodies 120 need to be maintained as a whole, the relevant operators can pull out the base 110 from the cabinet 200 through the first sliding structure 111. At this time, the multiple module bodies 120 installed on the base 110 through multiple installation positions are also taken out together; when there is a target module body 120 among the multiple module bodies 120 that needs to be maintained independently, the relevant operators can pull out the target module body 120 from the base 110 separately through the sliding cooperation of the third sliding structure 122 and the second sliding structure 112, thereby detaching it from the cabinet 200.

[0059] The power module 100 provided in the embodiment of the present application realizes the sliding installation of the base 110 on the cabinet 200 and the sliding installation of multiple module bodies 120 on the base 110 through the arrangement of the above-mentioned first sliding structure 111, the second sliding structure 112 and the third sliding structure 122. For users with different professional levels, it supports overall installation and disassembly while also having the function of independent installation and disassembly, thereby providing a variety of maintenance methods to choose from, thereby improving the flexibility of the entire power module 100 in maintenance.

[0060] In some embodiments, as shown in FIG. 2 to FIG. 6 , the base 110 may include a base body 113 and a baffle 114 .

[0061] The base body 113 may be provided with a first sliding structure 111 and a second sliding structure 112; a baffle 114 may be provided on the back of the base body 113, and the baffle 114 may be used to stop the module body 120. The module body 120 may be provided with a first positioning structure 123, and the baffle 114 may be provided with a second positioning structure 115 that cooperates with the first positioning structure 123.

[0062] The first positioning structure 123 may be a positioning pin, a positioning shaft or a spindle, and the second positioning structure 115 may be a positioning hole; or, the first positioning structure 123 may be a positioning hole, and the second positioning structure 115 may be a positioning pin, a positioning shaft or a spindle, etc. For example, in some embodiments, as shown in Figures 2-6, the first positioning structure 123 may be a positioning pin, and the second positioning structure 115 may be a positioning hole.

[0063] The first positioning structure 123 and the second positioning structure 115 can be provided in plurality, where "plurality" means 2 or more. For example, in some embodiments, as shown in Figures 2-3 and 8-9, two first positioning structures 123 are provided, and correspondingly, two second positioning structures 115 are also provided.

[0064] In this embodiment, as shown in Figures 2 to 6, when the module body 120 needs to be slidably installed on the base body 113, the third sliding structure 122 of the module body 120 can be aligned with the second sliding structure 112 of the base 110. When the module body 120 slides to the installation position along the extension direction of the second positioning structure 115, the first positioning structure 123 of the radiator 121 can be slowly inserted backward into the second positioning structure 115 of the baffle 114. When the baffle 114 stops at the module body 120, the module body 120 has been pushed to the maximum depth.

[0065] In other embodiments, when the module body 120 needs to be slidably installed on the base body 113, the third sliding structure 122 of the module body 120 can be aligned with the second sliding structure 112 of the base 110. When the module body 120 slides to the installation position along the extension direction of the second positioning structure 115, the first positioning structure 123 of the radiator 121 can be slowly inserted backward into the second positioning structure 115 of the baffle 114. When the baffle 114 stops at the module body 120, the module body 120 has been pushed to the maximum depth.

[0066] The power module 100 provided in the embodiment of the present application, through the arrangement of the above-mentioned baffle 114, the first positioning structure 123 and the second positioning structure 115, realizes the limitation of the installation depth of the module body 120 and the positioning of the third sliding structure 122 when sliding with the second sliding structure 112, thereby reducing the risk of derailment and jamming caused by installation misalignment of the module body 120, thereby improving the installation accuracy of the module body 120.

[0067] In some embodiments, as shown in FIG. 2-FIG . 3 , the base 110 may further include a reinforcement 116 . The reinforcement 116 may be installed between the baffle 114 and the base body 113 .

[0068] In this embodiment, as shown in Figures 2-3, the reinforcement 116 is a triangular reinforcement rib, and the reinforcement 116 can be connected to the baffle 114 by bolt connection, rivet connection or other connection methods, and the reinforcement 116 can be connected to the base body 113 by bolt connection, rivet connection or other connection methods.

[0069] It is understandable that if no reinforcement 116 is provided between the baffle 114 and the base body 113, the baffle 114 and the base body 113 are connected only by the fixing parts on one side. When the module body 120 needs to be slidably installed on the base body 113, the module body 120 slides backward at a certain speed. When the module body 120 contacts the baffle 114, the module body 120 will generate a certain impact force on the baffle 114. Under a long-term use cycle, the fixing parts between the baffle 114 and the base body 113 may become loose or even fall off.

[0070] When a reinforcement 116 is provided between the baffle 114 and the base body 113, the reinforcement 116 can provide a supporting force for the baffle 114. Even if the module body 120 impacts the baffle 114, the baffle 114 can withstand a certain impact force due to the further reinforcement of the reinforcement 116, thereby improving the stability and reliability of the connection between the baffle 114 and the base body 113.

[0071] In some embodiments, as shown in FIG. 1-FIG . 2 , FIG. 4 , and FIG. 11 - FIG. 12 , the power module 100 may further include an operating member 130 .

[0072] The operating member 130 may be detachably connected to the base 110 and the plurality of module bodies 120 .

[0073] The operating member 130 may include a connecting plate for connecting the base 110 and multiple module bodies 120 and a handle. The handle can be installed on the side of the connecting plate away from the multiple module bodies 120. One or more handles can be provided, where multiple means two or more. For example, in some embodiments, as shown in Figures 2-3, two handles can be provided.

[0074] The connection method between the operating member 130 and the base 110 may include but is not limited to a threaded connection, a snap connection or other detachable connection methods. For example, in some embodiments, the connection method between the operating member 130 and the base 110 is a threaded connection.

[0075] The connection method between the operating member 130 and the multiple module bodies 120 may include but is not limited to threaded connection, snap connection or other detachable connection methods. For example, in some embodiments, the connection method between the operating member 130 and the multiple module bodies 120 is threaded connection.

[0076] In actual implementation, as shown in Figures 1-2, 4 and 11-12, when multiple module bodies 120 need to be maintained as a whole, the relevant operator can pull the operating part 130 outward to pull the base 110 out of the cabinet 200 through the first sliding structure 111. At this time, the multiple module bodies 120 installed on the base 110 through multiple mounting positions are also brought out together; when there is a target module body 120 among the multiple module bodies 120 that needs to be maintained independently, the relevant operator can first remove the operating part 130, and then can separately pull the target module body 120 out of the base 110 through the sliding cooperation of the third sliding structure 122 and the second sliding structure 112, thereby leaving the cabinet 200.

[0077] The power module 100 provided in the embodiment of the present application realizes the overall modular installation and disassembly of multiple module bodies 120 through the setting of the above-mentioned operating member 130, and introduces a handle structure to provide an optimal fulcrum, which is convenient for users to grasp during installation and disassembly, reduces the working hours required for installation and disassembly, and improves the maintainability and convenience of the entire power module 100.

[0078] In some embodiments, as shown in FIG. 2 , the operating member 130 may be provided with a third positioning structure 131 , and the module body 120 may be provided with a fourth positioning structure 124 that cooperates with the third positioning structure 131 .

[0079] The third positioning structure 131 may be a positioning pin, a positioning shaft or a spindle, and the fourth positioning structure 124 may be a positioning hole; or, the third positioning structure 131 may be a positioning hole, and the fourth positioning structure 124 may be a positioning pin, a positioning shaft or a spindle, etc. For example, in some embodiments, as shown in Figures 2-6, the third positioning structure 131 may be a positioning hole, and the fourth positioning structure 124 may be a positioning pin.

[0080] In actual implementation, as shown in Figure 2, during the assembly process of the operating member 130, the third positioning structure 131 of the operating member 130 can be aligned with the fourth positioning structure 124 of the module body 120. After the fourth positioning structure 124 of the module body 120 is inserted into the third positioning structure 131 of the operating member 130, the operating member 130 is connected to the module body 120 by bolt connection or other detachable connection methods, and the operating member 130 is connected to the base 110 by bolt connection or other detachable connection methods.

[0081] The power module 100 provided in the embodiment of the present application realizes the positioning connection between the operating member 130 and the module body 120 through the setting of the above-mentioned third positioning structure 131 and the fourth positioning structure 124, and cooperates with the setting of the above-mentioned first positioning structure 123 and the second positioning structure 115 to further improve the accuracy of the sliding fit between the module body 120 and the base 110.

[0082] In some embodiments, as shown in Figures 2-3, the module body 120 may include a heat sink 121 and a power device 128 installed on the heat sink 121. The heat sink 121 may have a first air outlet 125 and a second air outlet 126. The base 110 may be provided with a vent 117 at the installation position. The first air outlet 125 may be docked with the vent 117, and a first seal 118 may be provided at the vent 117.

[0083] The power device 128 generates a large amount of heat during operation, and the heat sink 121 can be used to cool and dissipate the heat of the power device 128 .

[0084] The first sealing member 118 may be a sealing strip. The first sealing member 118 may be made of plastic, rubber, or silicone. For example, in some embodiments, the first sealing member 118 is made of rubber. The rubber material may include but is not limited to nitrile rubber, cloth-reinforced rubber, or fluororubber.

[0085] When a first seal 118 is provided at the vent 117, external air enters the radiator 121 from the second vent 126 and leaves the radiator 121 from the first vent 125. At the position where the first vent 125 and the vent 117 are connected, the first seal 118 can better fill the gap between the first vent 125 and the vent 117, prevent gas leakage between the radiator 121 and the base 110, effectively reduce the dust carried by the air duct airflow from leaking into the cabinet 200 to cause pollution, improve the air tightness between the radiator 121 and the base 110, and improve the protection capability of the entire electrical equipment 10.

[0086] In some embodiments, as shown in FIG. 4 and FIG. 10 , the module body 120 may be slidably engaged with the base 110 along a first direction, the plane where the first seal 118 is located may extend along a second direction, and the angle α between the first and second directions may be an acute angle.

[0087] Here, α may satisfy: 1°≤α≤30°. For example, in some embodiments, the angle α between the first direction and the second direction is 2.5°.

[0088] The first direction may be the A direction shown in FIG. 4 and FIG. 10 , and the second direction may be the B direction shown in FIG. 4 and FIG. 10 .

[0089] In actual implementation, as shown in Figures 4 to 6, the first direction can be a horizontal direction. When the module body 120 needs to be slidably installed on the base body 113, the third sliding structure 122 of the module body 120 can be aligned with the second sliding structure 112 of the base 110, and the module body 120 can slide to the installation position in the horizontal direction. During the entire sliding process, the bevel flange of the module body 120 at the first air outlet 125 is docked with the bevel flange of the base 110 at the vent 117, and both sides of the first seal 118 are evenly and controllably compressed by the module body 120 and the base 110. The first positioning structure 123 of the radiator 121 can be slowly inserted backward into the second positioning structure 115 of the baffle 114. When the baffle 114 stops at the module body 120, the module body 120 has been pushed to the maximum depth.

[0090] The power module 100 provided in the embodiment of the present application realizes the bevel flange docking between the module body 120 and the base 110 through the structural design in which the angle α between the first direction and the second direction is an acute angle, so that the first seal 118 is evenly and controllably compressed by the module body 120 and the base 110, further optimizing the sealing effect of the first seal 118. Combined with the design in which the first direction is horizontal, it is convenient for relevant operators to carry out assembly and disassembly work, while controlling the inclination within a reasonable range, thereby improving the volume utilization rate of the entire power module 100.

[0091] In some embodiments, as shown in Figures 1-10, the module body 120 may include a heat sink 121 and a power device 128 installed on the heat sink 121. The heat sink 121 may have a first air outlet 125 and a second air outlet 126. The second air outlet 126 can be used to connect with the second air duct 220 of the cabinet 200. The second air outlet 126 may be provided with a second seal 127.

[0092] The second sealing member 127 may be a sealing strip. The second sealing member 127 may be made of plastic, rubber, or silicone. For example, in some embodiments, the second sealing member 127 is made of rubber. The rubber material may include but is not limited to nitrile rubber, cloth-reinforced rubber, or fluororubber.

[0093] When a second seal 127 is provided at the second air outlet 126, external air enters the radiator 121 from the second air outlet 126. At the position where the second air outlet 126 and the second air duct 220 are connected, the second seal 127 can better fill the gap between the second air outlet 126 and the second air duct 220, thereby preventing gas leakage between the upper end of the radiator 121 and the cabinet 200, effectively reducing the dust carried by the airflow in the duct from leaking into the cabinet 200 and causing pollution, thereby improving the airtightness between the upper end of the radiator 121 and the cabinet 200 and improving the protection capability of the entire electrical equipment 10.

[0094] In some embodiments, as shown in FIG10 , the module body 120 may be slidably engaged with the base 110 along a first direction, the plane where the second sealing member 127 is located may extend along a third direction, and the angle β between the third direction and the first direction may be an acute angle.

[0095] Here, β may satisfy: 1°≤β≤30°. For example, in some embodiments, the angle β between the third direction and the first direction is 2.5°.

[0096] The first direction may be direction A shown in FIG. 10 , and the third direction may be direction C shown in FIG. 10 .

[0097] In actual implementation, as shown in Figures 10-12, the first direction can be a horizontal direction. When the power module 100 needs to be slidably installed on the cabinet 200, the base 110 and the module body 120 installed on the base 110 can be slid horizontally to the installation position through the first sliding structure 111. During the entire sliding process, the bevel flange of the module body 120 at the second air outlet 126 is docked with the bevel flange of the cabinet 200 at the second air duct 220, and both sides of the second seal 127 are evenly and controllably compressed by the module body 120 and the cabinet 200.

[0098] The power module 100 provided in the embodiment of the present application realizes the bevel flange docking between the upper end of the module body 120 and the cabinet 200 through the structural design in which the angle β between the third direction and the first direction is an acute angle, so that the second seal 127 is evenly and controllably compressed by the module body 120 and the cabinet 200, further optimizing the sealing effect of the second seal 127. Combined with the design that the first direction is a horizontal direction, it is convenient for relevant operators to carry out assembly and disassembly work, while controlling the inclination within a reasonable range, thereby improving the volume utilization rate of the entire power module 100.

[0099] The present application also discloses an electrical device 10 .

[0100] In some embodiments, as shown in FIG. 11 and FIG. 12 , the electrical device 10 includes: a cabinet 200 and any one of the power modules 100 described above.

[0101] The cabinet 200 is provided with a mounting groove 250 , which is provided with a fourth sliding structure 230 . The first sliding structure 111 and the fourth sliding structure 230 are slidably matched. The power module 100 is installed in the mounting groove 250 , and the base 110 is detachably connected to the cabinet 200 .

[0102] The first sliding structure 111 may include but is not limited to a slider, a slide plate or a pulley. For example, in some embodiments, as shown in FIG. 11 and FIG. 12 , the first sliding structure 111 is a slide plate, and the fourth sliding structure 230 is a slide rail.

[0103] The connection method between the base 110 and the cabinet 200 may include but is not limited to threaded connection, snap connection or other detachable connection methods. For example, in some embodiments, the connection method between the base 110 and the cabinet 200 is threaded connection.

[0104] In actual implementation, as shown in Figures 1-6 and 11-12, when the power module 100 is maintained, the detachable connection between the base 110 and the cabinet 200 can be released first. When multiple module bodies 120 need to be maintained as a whole, the relevant operator can pull the base 110 out from the installation slot 250 of the cabinet 200 in the horizontal direction through the sliding cooperation of the first sliding structure 111 and the fourth sliding structure 230. At this time, the multiple module bodies 120 installed on the base 110 through multiple installation positions are also brought out together; when there is a target module body 120 among the multiple module bodies 120 that needs to be maintained independently, the relevant operator can pull the target module body 120 out from the base 110 in the horizontal direction through the sliding cooperation of the third sliding structure 122 and the second sliding structure 112, thereby detaching it from the installation slot 250 of the cabinet 200.

[0105] The electrical device 10 may include but is not limited to an inverter, a power converter, or a transformer, etc., which is not limited here. For example, in some embodiments, the electrical device 10 is an inverter.

[0106] The electrical device 10 provided in the embodiment of the present application, through the setting of the above-mentioned power module 100, compared with the solution of separately installing and maintaining multi-phase modules, installs multiple module bodies 120 on the base 110 to form an integrated combination module, supports overall installation and disassembly, and also has the function of independent installation and disassembly, thereby providing a variety of maintenance methods to choose from, thereby improving the flexibility of the entire power module 100 in maintenance.

[0107] In some embodiments, as shown in FIG. 4 to FIG. 6 and FIG. 10 to FIG. 12 , a fifth positioning structure 140 may be provided on the back of the power module 100 , and the cabinet 200 may be provided with a sixth positioning structure cooperating with the fifth positioning structure 140 .

[0108] The fifth positioning structure 140 can be a positioning pin, a positioning shaft or a spindle, and the sixth positioning structure can be a positioning hole; or, the fifth positioning structure 140 can be a positioning hole, and the sixth positioning structure can be a positioning pin, a positioning shaft or a spindle, for example, in some embodiments, as shown in Figures 2-6, the fifth positioning structure 140 can be a positioning pin, and the sixth positioning structure can be a positioning hole.

[0109] The fifth positioning structure 140 and the sixth positioning structure can be provided in plurality, where "multiple" means 2 or more. For example, in some embodiments, as shown in Figures 2-3 and 8-9, there are 2 fifth positioning structures 140, and correspondingly, there are also 2 sixth positioning structures.

[0110] In actual implementation, as shown in Figures 4-6 and 10-12, the module body 120 and the base 110 can be provided with a fifth positioning structure 140. During the process of sliding the power module 100 into the cabinet 200, the first sliding structure 111 of the power module 100 can be aligned with the fourth sliding structure 230 of the cabinet 200. When the power module 100 slides horizontally to the installation position, the fifth positioning structure 140 of the power module 100 can be slowly inserted backward into the sixth positioning structure of the cabinet 200. At this time, the radial displacement of the power module 100 along the fifth positioning structure 140 is restricted.

[0111] The electrical device 10 provided in the embodiment of the present application realizes the positioning connection between the power module 100 and the cabinet 200 through the setting of the above-mentioned fifth positioning structure 140 and the sixth positioning structure, improves the accuracy of the sliding fit between the power module 100 and the cabinet 200, and at the same time limits the radial displacement of the power module 100 along the fifth positioning structure 140, and cooperates with multiple detachable connection methods to enhance the overall reliability and stability of the electrical device 10.

[0112] In some embodiments, as shown in Figures 11-12, the cabinet 200 may have a separated first air duct 210 and a second air duct 220, and the first air duct 210 and the second air duct 220 may be open on different walls of the mounting groove 250. The module body 120 may include a heat sink 121 and a power device 128 installed on the heat sink 121. The heat sink 121 may have a first air outlet 125 and a second air outlet 126. The base 110 may have a vent 117. The first air duct 210 may be docked with the vent 117. The vent 117 may be docked with the first air outlet 125. The second air duct 220 may be docked with the second air outlet 126, and the first air duct 210 may be provided with a third sealing member 240.

[0113] The third sealing member 240 may be a sealing strip. The third sealing member 240 may be made of plastic, rubber, or silicone. For example, in some embodiments, the third sealing member 240 is made of rubber. The rubber material may include but is not limited to nitrile rubber, cloth-reinforced rubber, or fluororubber.

[0114] In this embodiment, as shown in Figures 11-12, when a third seal 240 is provided at the first air duct 210, external air can enter the cabinet 200 through the second air duct 220, and then enter the radiator 121 from the second air outlet 126, and leave the radiator 121 from the first air outlet 125, and then enter the base 110 through the vent 117, and finally leave the cabinet 200 from the first air duct 210. At the position where the first air outlet 125 and the first air duct 210 are connected, the third seal 240 can better fill the gap between the first air outlet 125 and the first air duct 210, thereby preventing gas leakage between the lower end of the radiator 121 and the cabinet 200.

[0115] The electrical device 10 provided in the embodiment of the present application effectively reduces the dust carried by the air duct airflow from leaking into the cabinet 200 and causing pollution through the setting of the above-mentioned third seal 240, improves the airtightness between the lower end of the radiator 121 and the cabinet 200, and at the same time improves the protection capability of the entire electrical device 10, thereby extending the service life of the entire electrical device 10.

[0116] In some embodiments, as shown in FIG10 , the module body 120 slides with the base 110 along a first direction, the plane where the third seal 240 is located extends along a fourth direction, and the angle γ between the fourth direction and the first direction may be an acute angle.

[0117] Among them, γ can satisfy: 1°≤γ≤30°, the angle γ between the fourth direction and the first direction can be equal to the angle α between the first direction and the second direction. For example, in some embodiments, the angle α between the first direction and the second direction is 2.5°, and correspondingly, the angle γ between the fourth direction and the first direction is also 2.5°.

[0118] The first direction may be direction A shown in FIG. 10 , and the fourth direction may be direction D shown in FIG. 10 .

[0119] In actual implementation, as shown in Figures 10-12, the first direction can be a horizontal direction. When the power module 100 needs to be slidably installed on the cabinet 200, the power module 100 can slide to the installation position in the horizontal direction through the sliding cooperation of the first sliding structure 111 and the fourth sliding structure 230. During the entire sliding process, the bevel flange of the module body 120 at the first air outlet 125 is docked with the bevel flange of the cabinet 200 at the first air duct 210, and both sides of the third seal 240 are evenly and controllably compressed by the module body 120 and the cabinet 200.

[0120] The electrical equipment 10 provided in the embodiment of the present application realizes the bevel flange docking between the lower end of the module body 120 and the cabinet 200 through the structural design in which the angle γ between the above-mentioned fourth direction and the first direction is an acute angle, so that the third seal 240 is evenly and controllably compressed by the module body 120 and the cabinet 200, further optimizing the sealing effect of the third seal 240. The design of sliding cooperation between the first sliding structure 111 and the fourth sliding structure 230 in the horizontal direction facilitates the relevant operators to carry out assembly and disassembly work, while controlling the inclination within a reasonable range, thereby improving the volume utilization rate of the entire power module 100.
