Description

Technical Field

[0001] This utility model relates to the field of inverter profile technology, specifically to an inverter profile for heat dissipation. Background Technology

[0002] An inverter is an electrical device that converts direct current (DC) to alternating current (AC). During operation, the inverter generates a lot of heat due to power consumption. If this heat is not controlled or eliminated in a timely manner, it will shorten the lifespan of the electronic and electrical control components inside the inverter and reduce its stability.

[0003] Therefore, to solve the above problems, existing technologies, such as patent document with application number CN201420142769.2, disclose an inverter profile that adds heat sinks and tree-branch-shaped heat sinks to the inverter casing, effectively enhancing the heat dissipation function of the inverter casing. This casing is similar in shape to ordinary casings and has a simple structure, making it easy to install and replace on the inverter, and has low operating costs.

[0004] Although the technical solutions disclosed in the aforementioned patent documents enhance the heat dissipation function of the inverter casing, they still have limitations in practical use, specifically:

[0005] First, taking the technical solution disclosed in the aforementioned patent document as an example, when fixing the circuit board, due to space limitations, if there are multiple circuit boards, such as two, the methods chosen are mostly: 1. Selecting a large-volume heat sink profile for fixing. However, selecting such a large-volume heat sink profile for two circuit boards will result in insufficient material utilization and wasted costs; 2. Using screws or other components to stack the two circuit boards. However, this will present an installation problem. When stacking the two circuit boards with screws or other components, since there are no components inside the casing, fixing the first board is relatively convenient. However, when fixing the second board, because the space is occupied by the first circuit board, it is difficult for the user to operate when tightening the screws. It is difficult to properly control the screws to align with the screw holes. At the same time, if an operation error occurs, such as tightening too much and pressing the second board against the first board, the two circuit boards are likely to come into too close contact and generate heat accumulation.

[0006] Secondly, taking the technical solution disclosed in the aforementioned patent document as an example, when sealing and fixing the outer shell, there is a phenomenon where the cover used for sealing is not aligned with the seal, resulting in installation misalignment. That is, because the screw holes at the opening of the outer shell are small, when aligning, in order to fully seal the outer shell, it is easy to overlook the position of the screw holes, resulting in the third screw being misaligned with the screw hole on the outer shell after the first two screws are fixed.

[0007] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0008] This utility model provides an inverter profile for heat dissipation, aiming to solve the technical problems mentioned in the background art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a heat dissipation inverter profile, the inverter profile including a shell profile body;

[0010] Viewed from a cross-sectional perspective, the main body of the outer shell profile includes a first vertical plate, a second vertical plate, and a first horizontal plate; in the same plane, the first vertical plate and the second vertical plate are symmetrically arranged and spaced apart, and the first horizontal plate is arranged between the first vertical plate and the second vertical plate, and the first vertical plate and the second vertical plate are integrally connected to both ends of the first horizontal plate;

[0011] The first vertical plate, the first horizontal plate, and the second vertical plate are connected end to end to form a frame structure with an opening, and the first horizontal plate is provided corresponding to the opening;

[0012] Both the first vertical plate and the second vertical plate have a horizontal surface and an arched surface. The two horizontal surfaces are arranged opposite each other and are both located inside the frame structure. The two arched surfaces are arranged opposite each other and are both located outside the frame structure. The center of the arched surface is located inside the frame structure, so that the arched surface is formed as a surface that bulges outward from the frame structure and has an arc-shaped structure.

[0013] The arched surface has a groove, and a plurality of first heat dissipation ribs are integrally connected in the groove. The plurality of first heat dissipation ribs are distributed in the groove along the direction from one end of the horizontal plane to the other end.

[0014] The first horizontal plate has a protrusion that protrudes outward toward the frame structure. The surface of the first horizontal plate is provided with a plurality of second heat dissipation ribs on both sides of the protrusion that are located on the outside of the frame structure. The plurality of second heat dissipation ribs are distributed along the direction from one end to the other end of the first horizontal plate.

[0015] The surface of the protrusion is provided with a central screw hole located inside the frame structure;

[0016] The outer shell profile body also includes two bottom screw blocks, two first protrusions, two slot blocks, and two second protrusions;

[0017] The two bottom screw blocks, the two first protrusions, the two slot blocks, and the two second protrusions are all symmetrically arranged with respect to the axis of symmetry of the first vertical plate and the second vertical plate;

[0018] Along the straight line from the opening of the frame structure to the first horizontal plate, the two bottom screw blocks, the two first protrusions, the two slot blocks, and the two second protrusions are respectively connected one-to-one on the surfaces of the first vertical plate and the second vertical plate on opposite sides and are spaced apart.

[0019] A first mounting groove is formed between the first vertical plate, the bottom screw block disposed on the first vertical plate, and the first protrusion; a second mounting groove is formed between the second vertical plate, the bottom screw block disposed on the second vertical plate, and the first protrusion; the first mounting groove and the second mounting groove are combined to form a first mounting chamber for fixing the circuit board;

[0020] Each of the two card slots is provided with a third mounting slot, and the two third mounting slots form a second mounting chamber for fixing the circuit board.

[0021] Each of the two bottom screw blocks has a first screw hole;

[0022] Within the frame structure, both ends of the first horizontal plate and the second protrusion on the first vertical plate and the second protrusion on the second vertical plate are combined to form a second screw hole.

[0023] The surfaces of both bottom screw blocks have a protrusion extending outward from the frame structure.

[0024] The above plan is explained as follows:

[0025] In the above scheme, the first screw hole, the second screw hole, and the middle screw hole are all open circular structures. The center line connecting the two first screw holes and the two second screw holes forms a quadrilateral structure, which can ensure the stability during fixing.

[0026] In the above scheme, the central screw hole can be directly set on the protrusion, or it can be like... Figure 1 As shown, an arc-shaped block with an opening is provided on the protrusion, and the arc-shaped block is integrally connected to the protrusion.

[0027] In the above scheme, multiple first heat dissipation fins are set at equal intervals.

[0028] In the above scheme, the two protrusions are symmetrically arranged with reference to the axis of symmetry of the first vertical plate and the second vertical plate, and the protrusions are arranged parallel to the first vertical plate and the second vertical plate. Parallel arrangement is the preferred scheme. The protrusions can also be inclined towards the inside or outside of the frame structure.

[0029] In a further technical solution, the inverter profile also includes a cover profile for sealing the opening;

[0030] Viewed from a cross-sectional perspective, the cover profile includes a second transverse plate;

[0031] The second horizontal plate has a bent section at both ends, and the two bent sections are symmetrically arranged with respect to the axis of symmetry of the first vertical plate and the second vertical plate;

[0032] When the cover profile seals the opening, the bent section is configured to be inserted into the opening and serve as a limiting part to limit the movement of the second cross plate in a direction parallel to the first cross plate;

[0033] Each of the two bent segments is integrally connected to a bent abutment block on opposite sides. The bent abutment block has an abutment positioning surface, which abuts against the protrusion to limit the insertion of the bent segment.

[0034] The above design allows the cap profile to be quickly positioned at the opening from all directions (up, down, left, and right). The directions of up, down, left, and right are illustrated using the height directions of the first and second vertical plates as a reference.

[0035] A further technical solution is that an auxiliary groove block is provided on the opposite side surface of each of the two bending sections, and the two auxiliary groove blocks are symmetrically arranged with reference to the axis of symmetry of the first vertical plate and the second vertical plate;

[0036] The auxiliary slot block has an auxiliary positioning slot.

[0037] Two auxiliary positioning slots can also be used to create a compartment for positioning the circuit board.

[0038] A further technical solution involves setting the two bent sections to correspond one-to-one with the two bottom screw blocks in a clearance fit. If an interference or overfit were used, the insertion of the bent sections would be more difficult.

[0039] A further technical solution involves aligning the end faces of the multiple first heat dissipation ribs furthest from the groove with the arched surface. This results in: 1. a higher aesthetic appeal for the entire profile; 2. a longer first heat dissipation rib positioned in the central area, thus providing a larger heat dissipation area.

[0040] A further technical solution is that the periphery of the first heat dissipation fin has a wavy undulation. This design improves the heat dissipation effect of the first heat dissipation fin.

[0060] The first vertical plate 2, the first horizontal plate 4, and the second vertical plate 3 are connected end to end to form a frame structure with an opening, and the first horizontal plate 4 is provided corresponding to the opening;

[0061] Both the first vertical plate 2 and the second vertical plate 3 have a horizontal surface 5 and an arched surface 6. The two horizontal surfaces 5 are arranged opposite each other and are both located inside the frame structure. The two arched surfaces 6 are arranged back to back and are both located outside the frame structure. The center of the arched surface 6 is located inside the frame structure, so that the arched surface 6 is formed as a surface that bulges outward from the frame structure and has an arc-shaped structure.

[0062] The arched surface 6 has a groove 7, and a plurality of first heat dissipation ribs 8 are integrally connected in the groove 7. The plurality of first heat dissipation ribs 8 are distributed in the groove 7 along the direction from one end of the horizontal surface 5 to the other end.

[0063] The first horizontal plate 4 has a protrusion 9 that protrudes outward from the frame structure. The surface of the first horizontal plate 4 is provided with a plurality of second heat dissipation ribs 10 on both sides of the protrusion 9, which are located on the outside of the frame structure. The plurality of second heat dissipation ribs 10 are distributed along the direction from one end to the other end of the first horizontal plate 4.

[0064] The surface of the protrusion 9 is provided with a central screw hole 11 located inside the frame structure;

[0065] The outer shell profile body 1 also includes two bottom screw blocks 12, two first protrusions 13, two slot blocks 14, and two second protrusions 15;

[0066] The two bottom screw blocks 12, the two first protrusions 13, the two slot blocks 14, and the two second protrusions 15 are all symmetrically arranged with reference to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3.

[0067] Along the straight line from the opening of the frame structure to the first horizontal plate 4, the two bottom screw blocks 12, the two first protrusions 13, the two slot blocks 14 and the two second protrusions 15 are respectively connected one-to-one on the surfaces of the first vertical plate 2 and the second vertical plate 3 on opposite sides and are spaced apart.

[0068] A first mounting groove 16 is formed between the first vertical plate 2, the bottom screw block 12 disposed on the first vertical plate 2, and the first protrusion 13; a second mounting groove 17 is formed between the second vertical plate 3, the bottom screw block 12 disposed on the second vertical plate 3, and the first protrusion 13; the first mounting groove 16 and the second mounting groove 17 are combined to form a first mounting chamber for fixing the circuit board.

[0069] Each of the two card slot blocks 14 is provided with a third mounting slot 18, and the two third mounting slots 18 form a second mounting chamber for fixing the circuit board.

[0070] Each of the two bottom screw blocks 12 has a first screw hole 19;

[0071] Within the frame structure, both ends of the first horizontal plate 4 are combined with the second protrusion 15 on the first vertical plate 2 and the second protrusion 15 on the second vertical plate 3 to form a second screw hole 20.

[0072] The surfaces of the two bottom screw blocks 12 each have a protrusion 29 extending outward from the frame structure.

[0073] This utility model can use the first mounting slot 16 and the second mounting slot 17 to position and connect the circuit board. Compared with simple screw fixing, this method is quick and convenient to assemble, and can also reduce the probability of heat accumulation when the circuit board is stacked and positioned.

[0074] This utility model can quickly limit and fix the sealing profile 21 used for sealing by the cooperation of the protrusion 29 and the bottom screw block 12, and can prevent the sealing profile 21 from shifting position during fixing.

[0075] This invention can maximize the heat dissipation area and improve heat dissipation efficiency by using the first heat dissipation fin 8, the undulating portion 28 provided on the first heat dissipation fin 8, and the second heat dissipation fin 10.

[0076] This utility model can fix the assembled cover profile 21 and the outer shell profile body 1 through the middle screw hole 11, the bottom screw block 12 and the second screw hole 20, which satisfies the functionality and does not increase the difficulty of product extrusion production.

[0077] In this embodiment, the first screw hole 19, the second screw hole 20, and the central screw hole 11 are all circular structures with openings. The center line connecting the two first screw holes 19 and the two second screw holes 20 forms a quadrilateral structure, which can ensure the stability during fixing.

[0078] In this embodiment, the central screw hole 11 can be directly set on the protrusion 9, or as shown in the figure, an arc-shaped block with an opening can be set on the protrusion 9, and the arc-shaped block can be integrally connected with the protrusion 9.

[0079] In this embodiment, multiple first heat dissipation fins 8 are arranged at equal intervals.

[0080] In this embodiment, the two protrusions 29 are symmetrically arranged with reference to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3, and the protrusions 29 are arranged parallel to the first vertical plate 2 and the second vertical plate 3. Parallel arrangement is the preferred option. The protrusions 29 can also be inclined towards the inside or outside of the frame structure.

[0081] In some specific embodiments, the inverter profile further includes a cover profile 21 for sealing the opening;

[0082] Viewed from a cross-sectional perspective, the cover profile 21 includes a second horizontal plate 22;

[0083] The second horizontal plate 22 has a bent section 23 at both ends, and the two bent sections 23 are symmetrically arranged with respect to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3.

[0084] When the cover profile 21 seals the opening, the bent section 23 is configured to be inserted into the opening and serve as a limiting part to limit the movement of the second horizontal plate 22 in a direction parallel to the first horizontal plate 4.

[0085] Each of the two bent segments 23 is integrally connected to a bent abutment block 24 on opposite sides. The bent abutment block 24 has an abutment positioning surface 25, which abuts against the protrusion 29 to limit the insertion of the bent segment 23.

[0086] With the above design, the cover profile 21 can be quickly positioned at the opening from the top, bottom, left, and right directions. The top, bottom, left, and right directions are illustrated with reference to the height directions of the first vertical plate 2 and the second vertical plate 3.

[0087] Specifically, when the cover profile 21 is inserted into the outer shell profile body 1, the bent section 23 will be inserted into the opening and, through cooperation with the two bottom screw blocks 12, limit the tendency of the second horizontal plate 22 to move in a direction parallel to the first horizontal plate 4.

[0088] Furthermore, after the bent section 23 is inserted to a set depth, the abutment positioning surface 25 abuts against the protrusion 29 to limit the insertion of the bent section 23.

[0089] In some specific embodiments, an auxiliary groove block 26 is provided on the opposite side surface of each of the two bent sections 23, and the two auxiliary groove blocks 26 are symmetrically arranged with reference to the axis of symmetry of the first vertical plate 2 and the second vertical plate 3.

[0090] The auxiliary slot block 26 has an auxiliary positioning slot 27. Two auxiliary positioning slots 27 can also form a compartment for positioning the circuit board.

[0091] In some specific embodiments, the two bent segments 23 are respectively configured with a clearance fit to the two bottom screw blocks 12. If there is an overfit or interference fit, the bent segments 23 will be more difficult to insert.

[0092] In some specific embodiments, the end faces of the plurality of first heat dissipation ribs 8 away from the groove 7 are flush with the arched surface 6. 1. This improves the overall aesthetics of the profile; 2. The longer first heat dissipation ribs 8 are located in the middle area, thus providing a larger heat dissipation area.

[0093] In some specific embodiments, the periphery of the first heat dissipation fin 8 has a wavy undulation 28. The presence of the undulation 28 is equivalent to increasing the contact area between the first heat dissipation fin 8 and the outside world, so that the first heat dissipation fin 8 can obtain a better heat dissipation effect.

[0094] Working principle:

[0095] In use, the circuit board is directly inserted into the first mounting area chamber formed by the combination of the first mounting slot 16 and the second mounting slot 17, and the second mounting area chamber formed by the two third mounting slots 18; this operation allows for convenient installation of the circuit board for the integrated controller.

[0096] After fixing components such as the circuit board, the cover profile 21 can be fixed. That is, when the cover profile 21 blocks the opening, the bent section 23 is guided to be inserted into the opening. At this time, the bent section 23 will act as a limiting part to limit the movement of the second horizontal plate 22 in a direction parallel to the first horizontal plate 4.

[0097] At the same time, the insertion of the bent segment 23 is limited by the abutting positioning surface 25 on the bent abutting block 24.

[0098] This utility model can use the first mounting slot 16 and the second mounting slot 17 to position and connect the circuit board. Compared with simple screw fixing, this method is quick and convenient to assemble, and can also reduce the probability of heat accumulation when the circuit board is stacked and positioned.

[0099] This utility model can quickly limit and fix the sealing profile 21 used for sealing by the cooperation of the protrusion 29 and the bottom screw block 12, and can prevent the sealing profile 21 from shifting position during fixing.

[0100] This invention can maximize the heat dissipation area and improve heat dissipation efficiency by using the first heat dissipation fin 8, the undulating portion 28 provided on the first heat dissipation fin 8, and the second heat dissipation fin 10.

[0101] This utility model can fix the assembled cover profile 21 and the outer shell profile body 1 through the middle screw hole 11, the bottom screw block 12 and the second screw hole 20, which satisfies the functionality and does not increase the difficulty of product extrusion production.

[0102] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
