Description

Technical Field

[0001] This utility model relates to the field of heat dissipation mechanism technology, and specifically discloses a heat dissipation mechanism for electrical equipment. Background Technology

[0002] With the rapid development of power electronics technology, the power density of electrical equipment such as frequency converters, servo drives, and inverters is constantly increasing. The electronic components inside them generate a lot of heat during operation. If the heat cannot be dissipated in time, the equipment temperature will rise sharply, which will lead to component performance degradation, shortened lifespan, or even permanent damage. Therefore, efficient and reliable heat dissipation design is the key to ensuring the stable operation of electrical equipment.

[0003] Existing electrical equipment generally incorporates internal air cooling and has air vents on the outer casing for air intake and exhaust. However, due to limited internal space, the air cooling structure is usually concentrated in the upper part of the equipment, while the air intake vents are generally located in the lower part of the outer casing, resulting in weak heat dissipation. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a heat dissipation mechanism for electrical equipment to solve the problem of weak heat dissipation effect of electrical equipment in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The aforementioned electrical equipment heat dissipation mechanism includes a heat sink and a heat dissipation fan fixedly disposed in the middle of the inner cavity of the heat sink, and further includes:

[0007] Two mounting plates are symmetrically fixed at one end of the heat sink. Each mounting plate has a mounting plate adjustment groove on its opposite side, and a mounting insert is inserted through the mounting plate adjustment groove.

[0008] Several side holes are opened through the outer wall of the end of the mounting sleeve away from the heat sink. Each side hole has a sliding telescopic block. A cavity is opened inside the mounting sleeve, and a moving mechanism for driving the side hole telescopic block to move is provided in the cavity.

[0009] Furthermore, a connecting ring plate is fixedly installed at one end of the heat sink near the mounting plate, and a number of ring plate positioning screw holes are evenly spaced along the circumference on the outer surface of the connecting ring plate.

[0010] Furthermore, the connecting ring plate is circular in shape and is fixedly installed on the opposite sides of the two mounting plates. The opposite sides of the two mounting plates are arc-shaped and conform to the connecting ring plate.

[0011] Furthermore, mounting plate positioning holes are provided on the bottom of both sides of the outer surface of the mounting plate to match the positioning screw holes of the ring plate, and bolts are provided in the internal threads of the corresponding positioning screw holes of the ring plate and the mounting plate positioning holes.

[0012] Furthermore, a connecting cover is fixedly installed at the end of the heat sink away from the connecting ring plate. The outer surface of the connecting cover at the end away from the heat sink is provided with an external thread. The connecting cover is threaded with a hollow back cover through the external thread. The inner wall of the hollow back cover near the end of the external thread is provided with an internal thread to cooperate with the external thread.

[0013] Furthermore, an embedded protruding ring is fixedly installed on the inner wall of the connecting cover. The embedded protruding ring has an overall circular structure, and a filter plate is attached to the inner wall of the embedded protruding ring.

[0014] Furthermore, a protruding rod is fixedly provided in the middle of the inner cavity of the hollow back cover, and the end of the protruding rod away from the hollow back cover abuts against the filter plate.

[0015] Furthermore, the moving mechanism includes an inner rotating rod inside the insert and several linkage rotating rods. The inner rotating rod is rotatably mounted inside the insert, and the several linkage rotating rods are respectively connected between the inner rotating rod and several side hole telescopic blocks.

[0016] Furthermore, a fixing thread is provided on the outer surface of the end of the mounting tube away from the side hole of the mounting tube, and a nut is connected to the outer surface of the mounting tube through the fixing thread.

[0017] Furthermore, a rotating plate is fixedly installed at one end of the inner rotating rod near the side hole of the insert, and an arc-shaped spring is fixedly installed on one side of the rotating plate. The end of the arc-shaped spring away from the rotating plate is fixedly connected to the insert.

[0018] The beneficial effects of this utility model are:

[0019] This utility model allows for direct installation at the air vents on the equipment casing via a mounting plate. A mounting sleeve is inserted into the air vent, and a moving mechanism pulls out a side-hole telescopic block from the side hole of the sleeve, locking it inside the air vent. This clamps and assembles the entire equipment at the air vent. The addition of a cooling fan accelerates airflow, improving heat dissipation. Furthermore, the device is easy to install and remove, and the angle of the mounting plate and the position of the mounting sleeve can be adjusted according to actual installation needs, providing better adaptability.

[0025] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, the heat dissipation mechanism for the electrical equipment includes a heat dissipation shroud 1 and a heat dissipation fan 8 fixedly disposed in the middle of the inner cavity of the heat dissipation shroud 1, and further includes:

[0028] Two mounting plates 11 are symmetrically fixed at one end of the heat sink 1. Each of the two mounting plates 11 has a mounting plate adjustment groove 13 on its opposite side. A mounting insert 14 is inserted through the mounting plate adjustment groove 13.

[0029] A plurality of side holes 15 are formed through the outer wall of the end of the mounting sleeve 14 away from the heat sink 1. A side hole telescopic block 17 is slidably arranged in each of the side holes 15. A cavity is formed inside the mounting sleeve 14, and a moving mechanism for driving the side hole telescopic block 17 to move is provided in the cavity.

[0030] The moving mechanism includes an inner rotating rod 16 and several linkage rotating rods 18. The inner rotating rod 16 is rotatably mounted inside the mounting cylinder 14, and the several linkage rotating rods 18 are respectively connected between the inner rotating rod 16 and several side hole telescopic blocks 17.

[0031] The outer surface of the mounting sleeve 14 away from the side hole 15 is provided with a fixing thread, and a nut is connected to the outer surface of the mounting sleeve 14 through the fixing thread.

[0032] A rotating lever 20 is fixedly installed at one end of the inner rotating rod 16 near the side hole 15 of the insert. An arc-shaped spring part 19 is fixedly installed on one side of the rotating lever 20. The end of the arc-shaped spring part 19 away from the rotating lever 20 is fixedly connected to the insert 14.

[0033] With the above configuration, the cooling fan 8 is installed inside the heat sink 1 via a bracket. The heat sink 1 has a built-in power supply and can be charged. A protruding plate is fixedly installed on the inner wall of the mounting sleeve 14 in conjunction with the arc-shaped spring part 19. Each set of mounting plates 11 is provided with two sets of plate adjustment grooves 13. The mounting sleeve 14 can be slidably placed in the plate adjustment groove 13, and the position of the mounting sleeve 14 can be adjusted so that the mounting sleeve 14 can pass through the air inlet of the electrical equipment and extend into the interior of the electrical equipment. Since one end of the mounting sleeve 14 is provided with a fixing thread, the mounting sleeve 14 can be restricted in the plate adjustment groove 13 by a nut.

[0034] To enhance the connection, several circumferentially distributed side holes 15 are formed through the outer wall of the end of the mounting sleeve 14 away from the heat sink 1. Each set of side holes 15 has a slidingly connected side hole telescopic block 17 that can protrude outwards. The side hole telescopic block 17 is driven by a moving mechanism, which includes an inner rotating rod 16 and several linkage rotating rods 18. The inner rotating rod 16 is rotatably connected inside the mounting sleeve 14, and the linkage rotating rods 18 are respectively connected between the inner rotating rod 16 and the several side hole telescopic blocks 17. A rotating dial 20 is fixedly installed at the end of the inner rotating rod 16 near the side hole 15, and an arc-shaped spring part 19 is fixedly installed on one side of the rotating dial 20. In the default state, the side hole telescopic block 17 protrudes from the side hole 15. First, rotating the inner rotating rod 16 drives the rotating dial 20 to rotate, which in turn compresses the arc-shaped spring part 19. One end of the spring portion 19 away from the rotating dial 20 is fixedly connected to the protruding plate on the inner wall of the mounting tube 14, that is, the arc-shaped spring portion 19 is compressed towards the protruding plate. At this time, the side hole telescopic block 17 retracts into the side hole 15 of the tube, so that the mounting tube 14 can be inserted into the air intake hole of the air intake device. Then, the inner rotating rod 16 of the tube is released, and the rotating dial 20 and the inner rotating rod 16 of the tube are driven to rotate in opposite directions by the elastic action of the arc-shaped spring portion 19. At this time, several linkage rotating rods 18 rotate synchronously, pushing the side hole telescopic block 17 to move outward from the side hole 15 of the tube, so that the side hole telescopic block 17 is engaged in the air intake grille. Then, the nut at one end of the mounting tube 14 is tightened. The grille is clamped by the side hole telescopic block 17 and the nut to keep the mounting plate 11 installed stably. One end of the inner rotating rod 16 of the tube passes through the mounting tube 14 and extends to the side of the heat sink 1, so that the inner rotating rod 16 of the tube can be rotated and adjusted outside the mounting tube 14.

[0035] A connecting ring plate 9 is fixedly installed at one end of the heat sink 1 near the mounting plate 11. The outer surface of the connecting ring plate 9 is provided with a number of ring plate positioning screw holes 10 evenly spaced along the circumference.

[0036] The connecting ring plate 9 is circular in shape and is fixedly installed on the opposite sides of the two mounting plates 11. The opposite sides of the two mounting plates 11 are arc-shaped and adapted to the connecting ring plate 9.

[0037] The bottom of both sides of the outer surface of the mounting plate 11 is provided with mounting plate positioning holes 12 to match the positioning screw holes 10 of the ring plate, and the corresponding internal threads of the positioning screw holes 10 of the ring plate and the mounting plate positioning holes 12 are provided with bolts.

[0038] With the above settings, after the mounting plate positioning hole 12 is aligned with the ring plate positioning screw hole 10, the mounting plate 11 can be fixedly installed on the outer surface of the connecting ring plate 9 by bolts. Thus, the mounting plate 11 can be fixedly installed outside the heat sink 1, and different numbers of mounting plates 11 can be installed according to actual usage requirements.

[0039] A connecting cover 3 is fixedly installed at the end of the heat sink 1 away from the connecting ring plate 9. The outer surface of the connecting cover 3 away from the heat sink 1 is provided with a connecting external thread part 5. The connecting cover 3 is threaded with a hollow back cover 2 through the connecting external thread part 5. The inner wall of the hollow back cover 2 near the connecting external thread part 5 is provided with an internal thread to cooperate with the connecting external thread part 5.

[0040] An embedded protruding ring 4 is fixedly installed on the inner wall of the connecting cover 3. The embedded protruding ring 4 has an overall circular structure, and the filter plate 6 is attached to the inner wall of the embedded protruding ring 4.

[0041] A protruding rod 7 is fixedly provided in the middle of the inner cavity of the hollow back cover 2. The end of the protruding rod 7 away from the hollow back cover 2 abuts against the filter plate 6.

[0042] With the above configuration, the protruding rod 7 is fixedly located in the middle of the inner cavity of the hollow back cover 2 on the side away from the heat sink 1; after the hollow back cover 2 is threaded to the connecting external thread 5, the protruding rod 7 abuts against the filter plate 6, which can press the filter plate 6 tightly against the embedded protruding ring 4, thereby facilitating the subsequent removal and replacement of the filter plate 6.
