Description

Technical Field

[0001] This utility model relates to the field of power electronic equipment structure and installation technology, and in particular to a power module air duct installation structure. Background Technology

[0002] Power modules are widely used in various industrial environments, many of which are rich in pollutants, especially dust, which can severely damage the internal components and circuit boards of power modules. Except for power modules with IP54 or higher ratings used in specialized industries, many general-purpose power modules have ventilation holes for heat dissipation. However, because the air duct is not isolated from the component installation area, a large amount of pollutants enters the installation area. Over time, this leads to a significant increase in the failure rate of components and circuit boards, severely reducing the lifespan of the power module. It can also cause the cooling system to fail, increasing operating and maintenance costs and shortening equipment lifespan. Current power module and air duct installation structures require opening the baffle and air duct sealing frame before installing the power module, and again during disassembly and maintenance to remove the power module. This process is cumbersome and inefficient. Furthermore, the presence of the baffle also results in a large space occupied by the air duct frame. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a duct installation structure for power modules, which aims to solve the problems of cumbersome steps, low efficiency and large space occupation when installing power modules in ducts and disassembling and maintaining power modules.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a duct installation structure for a power module, including at least one duct frame with an installation slope as the installation surface, a power module, and a wedge-shaped module fixed between the power module and the installation slope, wherein the wedge-shaped slope of the wedge-shaped module is parallel to the installation slope.

[0006] Furthermore, it also includes a fixing plate with one end fixed to the power module or wedge module and the other end fixed to the air duct frame.

[0007] Furthermore, the wedge-shaped module has sealing strips around its wedge-shaped bevel.

[0008] Furthermore, a first guide rail is provided on at least one mounting surface.

[0009] Furthermore, the air duct frame is provided with an air inlet and an air outlet, which are respectively located on different mounting surfaces.

[0010] Furthermore, the two ends of the power module near the mounting surface, one end of the wedge-shaped module's inclined surface, and the end of the wedge-shaped module that contacts the power module are all open and connected to the air inlet and air outlet.

[0011] Furthermore, a first limiting member is provided around the contact end between the wedge-shaped module and the power module.

[0012] Furthermore, the contact surface between the power module and the wedge module is provided with a second guide rail, and the contact ends of the wedge module and the power module are provided with second limiting members on both sides.

[0013] Furthermore, the mounting surface of the air duct frame includes two mounting ramps.

[0014] Furthermore, the mounting surface of the duct frame includes a mounting ramp and a mounting plane.

[0015] The advantages of this utility model compared with the prior art are:

[0016] This utility model provides a duct installation structure for a power module, including at least one duct frame with an installation slope as the installation surface, a power module, and a wedge-shaped module fixed between the power module and the installation slope, wherein the wedge-shaped slope of the wedge-shaped module is parallel to the installation slope.

[0017] The duct installation structure of this utility model adopts a plug-in structure. When installing the power module, there is no need to open the baffle and the duct sealing frame in advance; the power module and the wedge module can be directly pushed into the duct. When maintenance is required for the power module, the fixing plate can be removed to directly pull out the power module for maintenance. The duct frame does not require a baffle, and the entire installation structure occupies less space. Sealing strips are installed around the inclined surface of the wedge module. After the wedge module is pushed into the corresponding position in the duct, the duct is sealed. Compared with the case where the mounting surfaces of the duct frame are all flat, the parallel arrangement of the wedge inclined surface and the mounting inclined surface ensures that no friction is generated between the wedge module and the mounting inclined surface during the process of pushing the power module into the duct until the wedge module contacts the mounting inclined surface. Combined with the guide rail setting, the resistance encountered during the entire installation process is very small.

[0018] The power module air duct installation structure provided by this utility model does not require a baffle plate or air duct sealing frame. The structure is simple and the installation operation is convenient, which improves the efficiency of installing or disassembling the power module. The air duct is sealed after the power module and air duct are assembled and fixed. The structure has high reliability. The absence of a baffle plate makes the overall structure smaller and saves space.

In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification.

Detailed Implementation

[0029] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0034] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] like Figure 1 - Figure 2 As shown, a prior art power module 104 and air duct installation structure includes a baffle plate 101 and a channel sealing plate, and both the upper and lower mounting surfaces are mounting planes 111. When the power module 104 is installed into the air duct, since there is still a certain gap between the top of the power module 104 and the mounting surface, it is necessary to open the baffle plate 101 to manually carry the air duct sealing frame 102 to the air outlet 110 and install the air duct sealing frame 102 at the air outlet 110 position. Pressing the air duct sealing frame 102 will cause the sealing strip 108 on it to contact the upper end of the power module 104, thereby filling the gap between the top of the power module 104 and the mounting surface, achieving the purpose of air duct sealing. However, the installation structure of the power module 104 and the air duct is relatively complex, and the actual installation operation is quite complicated. Moreover, when the power module 104 is disassembled and maintained, the baffle plate 101 and the air duct sealing frame 102 must be opened again to remove the power module 104, which affects the efficiency of the installation and disassembly of the power module 104. The presence of the baffle plate 101 makes the air duct frame 105 larger in size.

[0036] like Figure 3 - Figure 6 As shown, this utility model discloses a duct installation structure for a power module 104, including at least one duct frame 105 with an installation slope 112 as the mounting surface, a power module 104, and a wedge-shaped module 103 fixed between the power module 104 and the installation slope 112. The wedge-shaped slope 115 of the wedge-shaped module 103 is parallel to the installation slope 112. The duct installation structure for the power module 104 provided by this utility model does not require a baffle plate 101 and a duct sealing frame 102. The structure is simple and the installation operation is convenient, which improves the efficiency of installing or disassembling the power module 104. The duct is sealed after the power module 104 is assembled and fixed with the duct. The structure has high reliability. The absence of a baffle plate 101 makes the overall structure smaller and saves space.

[0037] It should be noted that the parallel arrangement of the wedge-shaped inclined surface 115 and the mounting inclined surface 112 ensures that during the process of pushing the power module 104 into the air duct, no friction is generated between the wedge-shaped module 103 and the mounting inclined surface 112 until the wedge-shaped module 103 contacts the mounting inclined surface 112. Combined with the guide rail arrangement, the resistance encountered during the entire installation process is very small.

[0038] In one embodiment, the wedge-shaped inclined surface 115 of the wedge module 103 is provided with sealing strips 108 around it. When the power module 104 is pushed into the air duct frame 105 until the sealing strips 108 on the wedge-shaped inclined surface 115 come into contact with and are pressed against the mounting inclined surface 112, the air duct is sealed.

[0039] In one embodiment, the air duct mounting structure of the power module 104 further includes a fixing plate 107 with one end fixed to the power module 104 or the wedge module 103 and the other end fixed to the air duct frame 105.

[0040] Specifically, the fixing plate 107 is used to further fix the power module 104 to the air duct frame 105. When it is necessary to disassemble the power module 104 for maintenance, the fixing plate 107 must be opened first and then the power module 104 can be taken out.

[0041] It should be noted that when the power module 104 is provided with a hanging ear or a buckle, the power module 104 or the wedge module 103 can also be fixed to the air duct frame 105 by using the hanging ear or the buckle.

[0042] In one embodiment, such as Figure 5 As shown, the air duct mounting structure of the power module 104 has two mounting surfaces, and each mounting surface is provided with a first guide rail 106 arranged along the mounting direction of the power module 104. Specifically, each mounting surface is provided with two first guide rails 106, the two first guide rails 106 on the same mounting surface are parallel to each other, and the distance between the first guide rails 106 is equal to the width of the bottom of the power module 104.

[0043] like Figure 5 As shown, the mounting surface of the duct frame 105 includes a mounting ramp 112 and a mounting plane 111. The duct frame 105 is provided with an air inlet 109 and an air outlet 110, which are respectively located on different mounting surfaces. Specifically, the air inlet 109 is located on the mounting plane 111, and the air outlet 110 is located on the mounting ramp 112. When the duct is working, the air flowing in through the air inlet 109 passes through the power module 104 and flows out through the air outlet 110.

[0044] Specifically, the two ends of the power module 104 near the mounting surface, one end of the inclined surface of the wedge module 103, and the end of the wedge module 103 that contacts the power module 104 are all open, that is, the air blown in from the air inlet 109 can pass through the interior of the power module 104 and the interior of the wedge module 103 in sequence before reaching the air outlet 110 to perform air cooling of the power module 104.

[0045] In one embodiment, such as Figure 5-6 As shown, a first limiting member 113 is provided around the contact end between the wedge module 103 and the power module 104. Specifically, the first limiting member 113 is located at the bottom of the wedge module 103 and covers part of the area around the top of the power module 104. When the power module 104 is installed into the air duct frame 105 and moved into the first guide rail 106 by manual or mechanical means, the wedge module 103 will be limited above the power module 104 by the first limiting member 113 and enter the air duct frame 105 together with the power module 104.

[0046] In one embodiment, a second guide rail 116 (not shown in the figure) is provided on the contact surface between the power module 104 and the wedge module 103, and second limiting members 114 are provided on both sides of the contact end between the wedge module 103 and the power module 104. Specifically, a second guide rail 116 (not shown in the figure) is provided at the top of the power module 104, and a second limiting member 114 is provided at the bottom of the wedge module 103, covering a portion of the area on both sides of the top of the power module 104.

[0047] Specifically, when installing the power module 104 onto the duct frame 105, the power module 104 is first pushed into the first guide rail 106. After the power module 104 reaches the installation position, the wedge module 103 is pushed into the second guide rail 116 (not shown in the figure) to the corresponding position. The power module 104 and the wedge module 103 are then installed separately. The second guide rail 116 (not shown in the figure) on the top of the power module 104 helps to reduce the friction generated when the wedge module 103 enters the duct frame 105. The second limiting member 114 is only provided on both sides of the contact end between the wedge module 103 and the power module 104 to ensure that the movement of the wedge module 103 in the direction of the second guide rail 116 (not shown in the figure) is not affected by the limiting member, and also to ensure that the wedge module 103 will not wobble left and right during the installation process.

[0048] In one embodiment, the mounting surface of the duct frame 105 includes two mounting ramps 112. Specifically, this embodiment also includes two wedge-shaped modules 103, which are respectively fixed between the power module 104 and the different mounting ramps 112.

[0049] With the mounting surface set as the mounting slope 112, during the installation of the power module 104, the sealing strip 108 on the wedge module 103 does not generate friction with the mounting slope 112. When the wedge module 103 comes into contact with the mounting slope 112 and generates friction, the power module 104 and the wedge module 103 are also pushed to the corresponding installation position to complete the installation.

[0050] This utility model provides a duct installation structure for a power module 104, including at least one duct frame 105 with an installation surface 112, a power module 104, and a wedge-shaped module 103 fixed between the power module 104 and the installation surface 112, wherein the wedge-shaped inclined surface 115 of the wedge module 103 is parallel to the installation surface 112.

[0051] The duct installation structure of this utility model adopts a plug-in structure. When installing the power module 104, it is not necessary to open the baffle plate 101 and the duct sealing frame 102 in advance; the power module 104 and the wedge module 103 can be directly pushed into the duct. When maintenance is required on the power module 104, the fixing plate 107 can be removed to directly pull out the power module 104 for maintenance. The duct frame 105 does not require the baffle plate 101, and the entire installation structure occupies less space. Around the inclined surface of the wedge module 103... After installing the sealing strip 108 and pushing the wedge module 103 into the corresponding position in the air duct, the air duct is sealed. Compared with the mounting surface 111 of the air duct frame 105, the wedge slope 115 is set parallel to the mounting slope 112, so that no friction is generated between the wedge module 103 and the mounting slope 112 during the process of pushing the power module 104 into the air duct until the wedge module 103 contacts the mounting slope 112. Combined with the guide rail, the resistance encountered during the entire installation process is very small.

[0052] The power module 104 provided by this utility model has an air duct installation structure that does not require a baffle plate 101 and an air duct sealing frame 102. The structure is simple and the installation operation is convenient, which improves the efficiency of installing or disassembling the power module 104. The air duct is sealed after the power module 104 is assembled and fixed with the air duct. The structure has high reliability. The absence of a baffle plate 101 makes the overall structure smaller and saves space.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
