Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and in particular to a heat dissipation device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] The function of electrical connection structures is to ensure the efficient and safe transmission of electrical energy from the power source to the electrical equipment, while simultaneously realizing circuit control, distribution, protection, and signal transmission, ensuring the stable operation of the electrical system and the normal operation of the equipment. Switchgear is a type of electrical connection structure, achieving electrical connections through internal switching equipment, busbars, cables, and other components, thereby fulfilling the functions of power system control, protection, and energy distribution. Generally, the equipment inside the switchgear generates heat during operation, and heat sinks and fans are installed inside the cabinet to conduct heat from the heat-generating equipment to the outside. However, over long-term use, dust gradually accumulates on the heat sinks, affecting their heat dissipation efficiency. Current methods typically involve manual dust cleaning, which has the following drawbacks: 1. The cabinet contains numerous devices, making cleaning cumbersome and prone to accidental contact with equipment during cleaning; 2. Dust easily scatters during cleaning, affecting the equipment's heat conduction efficiency. Therefore, a heat dissipation device has been proposed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a heat dissipation device that efficiently cleans dust without scattering it everywhere.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a heat dissipation device, comprising:

[0006] The heat sink comprises multiple fins arranged in a longitudinal array.

[0007] A cooling fan with its air outlet facing upwards is located at the bottom of the heat sink, and the cooling fan is used to perform air cooling on the heat sink.

[0008] A drive assembly, which is disposed on the heat sink;

[0009] A cleaning component is disposed at the moving end of the drive component, which can drive the cleaning component to reciprocate along the width direction of each fin and brush off the dust on each fin.

[0010] The dust suction component, located at the moving end of the drive component, is used to suck up the dust that is cleaned up when the cleaning component brushes the fins.

[0011] Furthermore, mounting brackets are provided on both sides of the heat sink. The drive assembly includes a reciprocating screw and a guide rod respectively mounted on the corresponding mounting bracket. The reciprocating screw and the guide rod are both arranged along the width direction of the fin. A threaded sleeve and a guide sleeve are respectively provided on the reciprocating screw and the guide rod. The threaded sleeve is threadedly engaged with the reciprocating screw. The guide sleeve is slidably sleeved on the guide rod. Mounting rings are rotatably provided on both the threaded sleeve and the reciprocating screw. Each mounting ring is respectively sleeved on the corresponding reciprocating screw and the guide rod. The mounting bracket has a guide groove that is strip-shaped and arranged along the width direction of the fin. A limiting rod that can be slidably inserted into the guide groove is provided on the mounting ring. A gear ring is provided on the threaded sleeve. A mounting seat is provided on the mounting ring. A running assembly is provided on the mounting seat. The running assembly includes a motor and a gear mounted on the motor shaft. The gear meshes with the gear ring. The running assembly is used to drive the gear ring to rotate and drive the threaded sleeve to rotate synchronously.

[0012] When the threaded sleeve rotates, it can reciprocate on the reciprocating screw. In conjunction with the limiting rod and guide groove, it can drive the mounting ring and mounting base to reciprocate along the width direction of the heat sink.

[0013] Furthermore, the dust collection assembly includes a detachable dust collection pipe mounted on the mounting base. The dust collection pipe has multiple air inlets, each of which faces between two adjacent fins. A filter plate is provided at the air outlet of the dust collection pipe, and an exhaust assembly is provided at the end of the filter plate away from the dust collection pipe. The exhaust assembly is used to create a negative pressure inside the dust collection pipe, allowing dust and air to enter the dust collection pipe from the air inlets.

[0014] Furthermore, the exhaust assembly includes a suction fan, the suction end of which is connected to the filter plate. When the suction fan is working, it can work with the dust suction pipe to suck up the dust from the corresponding fins of the heat sink.

[0015] Furthermore, the exhaust assembly includes a fan assembly disposed on the side of the filter plate away from the suction pipe. The fan assembly includes a housing that communicates with the suction pipe, a fan body rotatably disposed within the housing, and an exhaust port opened on the housing. A bevel gear set is disposed on the housing. The bevel gear set consists of a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is coaxially disposed on the fan body, and the second bevel gear is rotatably disposed on a mounting base. A transmission belt set is disposed on the second bevel gear and the motor shaft. The transmission belt set consists of two transmission pulleys and a transmission belt that drives the two transmission pulleys. The two transmission pulleys are coaxially disposed on the second bevel gear and the motor shaft, respectively.

[0016] Furthermore, the cleaning assembly includes a plurality of brush rods arranged longitudinally at the bottom of the mounting base, each brush rod being located between each pair of adjacent fins.

[0017] The beneficial effects of this utility model are reflected in:

[0018] This invention allows for the activation of a drive component when a significant amount of dust accumulates on the heat sink and cleaning is required. The cleaning component then reciprocates along the width of the heat sink, with its cleaning end extending into the gaps between the fins and brushing off the dust. During this process, a dust collection component works, sucking the brushed-off dust into its interior for temporary storage. Operators only need to periodically clean the dust inside the dust collection component. This cleaning method is highly efficient and rapid throughout, preventing excessive dust from scattering and affecting the normal operation of the equipment within the switch cabinet.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figure 1-5 This utility model discloses a heat dissipation device, including a heat sink 1. The heat sink 1 includes multiple fins arranged in a longitudinal array, with a gap between each pair of fins. A cooling fan 2 is installed at the bottom of the heat sink 1. The cooling fan 2 is used to perform air cooling on the heat sink 1. In use, the heat-absorbing end of the heat sink 1 is attached to the heat-generating end of the heat dissipation device. The heat sink 1 can increase the heat dissipation area. With the operation of the cooling fan 2, the heat at the heat sink 1 is transferred from bottom to top to the outside of the switch cabinet through airflow, thereby achieving heat dissipation. This heat dissipation method is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0028] In one embodiment, a drive assembly 4 is provided on the heat sink 1, and a cleaning assembly is provided at the moving end of the drive assembly 4. The drive assembly 4 can drive the cleaning assembly to reciprocate along the width direction of each fin and brush off the dust on each fin. The moving end of the drive assembly 4 is also provided with a dust suction assembly, which is used to suck up the dust cleaned off when the cleaning assembly brushes each fin.

[0029] In practice, when a lot of dust accumulates on the heat sink 1 and needs to be cleaned, the drive component 4 can be activated. At this time, the cleaning component will move back and forth along the width of the heat sink 1, and its cleaning end will extend into the gaps of the heat sink 1 and brush off the dust on the fins. During this process, the dust collection component will work and suck the brushed dust into its interior for temporary storage. The staff only needs to clean the dust inside the dust collection component periodically. This cleaning method is efficient and fast throughout and will not allow too much dust to fly around and affect the normal use of the equipment in the switch cabinet.

[0030] It should be noted that when cleaning the dust on the heatsink 1, the cooling fan 2 needs to be turned off to ensure that the dust does not fly around when it is brushed off the heatsink 1.

[0031] In one embodiment, mounting brackets 3 are installed on both sides of the heat sink 1. The drive assembly 4 includes a reciprocating screw 41 and a guide rod 42 respectively mounted on the corresponding mounting brackets 3. The reciprocating screw 41 and the guide rod 42 are both arranged along the width direction of each fin. Threaded sleeves 43 and guide sleeves 44 are respectively provided on the reciprocating screw 41 and the guide rod 42. The threaded sleeve 43 is threadedly engaged with the reciprocating screw 41, and the guide sleeve 44 is slidably sleeved on the guide rod 42. Mounting rings 45 are rotatably mounted on both the threaded sleeve 43 and the reciprocating screw 41. Each mounting ring 45 is respectively sleeved onto the corresponding... On the reciprocating screw 41 and guide rod 42, the mounting bracket 3 has a guide groove 46 that is arranged in the width direction of each fin and is strip-shaped. A limit rod that can be slidably inserted into the guide groove 46 is installed on the mounting ring 45. A gear ring 47 is installed on the threaded sleeve 43. A mounting base 49 is installed on the mounting ring 45. A running component 48 is provided on the mounting base 49. The running component 48 includes a motor installed on the mounting base 49 and a gear installed on the motor shaft. The gear meshes with the gear ring 47. The running component 48 is used to drive the gear ring 47 to rotate and drive the threaded sleeve 43 to rotate synchronously.

[0032] In practice, after the motor starts, the gear will rotate, and the gear will drive the meshing gear ring 47 to rotate together. During this process, the threaded sleeve 43 will rotate synchronously. When the threaded sleeve 43 rotates, it can reciprocate on the fixed reciprocating screw 41. With the help of the limit rod and the guide groove 46, it can drive the mounting ring 45 and the mounting base 49 to reciprocate along the width direction of the heat sink 1. The guide sleeve 44 slides on the guide rod 42 to ensure its movement stability. The cleaning component and the dust collection component will move synchronously with the mounting base 49.

[0033] In one embodiment, the vacuuming assembly includes a vacuuming pipe 5 detachably mounted on a mounting base 49. The vacuuming pipe 5 has multiple air inlets, each facing between two adjacent fins. A filter plate (not shown in the figure) is installed at the air outlet of the vacuuming pipe 5. An exhaust assembly 6 is installed at the end of the filter plate away from the vacuuming pipe 5. The exhaust assembly 6 is used to create a negative pressure inside the vacuuming pipe 5, allowing dust and air to enter the vacuuming pipe 5 from the air inlets.

[0034] In practice, when the exhaust assembly 6 is working, a negative pressure is formed inside the suction pipe 5, and the dust brushed off by the cleaning assembly is drawn into the suction pipe 5 from the air inlet. The air passes through the filter plate and is discharged from the air outlet of the suction pipe 5, while the dust is blocked by the filter plate and thus remains inside the suction pipe 5. Since the suction pipe 5 is detachably installed on the mounting base 49, the staff can clean the dust inside it after removing the suction pipe 5. This method can effectively improve the efficiency of dust handling. The corresponding structure for disassembly and installation is common knowledge in the field, so its specific structure will not be described in detail in this article.

[0035] In one embodiment, the exhaust assembly 6 includes a suction fan 61, the suction end of which is connected to the filter plate.

[0036] With this design, when the suction fan 61 is working, it can work with the suction pipe 5 to suck up the dust from the corresponding fins of the heat sink 1.

[0037] In one embodiment, the exhaust assembly 6 includes a fan assembly 62 mounted on the side of the filter plate away from the suction pipe 5. The fan assembly 62 includes a housing that communicates with the suction pipe 5, a fan body that is rotatably mounted inside the housing, and an exhaust port opened on the housing. A bevel gear set 63 is provided on the housing. The bevel gear set 63 consists of a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is coaxially mounted on the fan body, and the second bevel gear is rotatably mounted on the mounting base 49. A transmission belt set 64 is provided on the second bevel gear and the motor shaft. The transmission belt set 64 consists of two transmission wheels and a transmission belt that drives the two transmission wheels. The two transmission wheels are coaxially mounted on the second bevel gear and the motor shaft, respectively.

[0038] In practice, when the motor starts and drives the mounting base 49 to reciprocate, its shaft will also work with the transmission belt group 64 and the bevel gear group 63 to drive the fan body to rotate. The rotation of the fan body will have a negative pressure suction effect, so that the dust brushed off is sucked into the dust suction pipe 5. The air passes through the filter plate and is discharged from the exhaust port. This method can perform dust cleaning and absorption simultaneously with a single power source, making it more flexible to use.

[0039] In one embodiment, the cleaning assembly includes a plurality of brush rods 7 longitudinally mounted at the bottom of the mounting base 49, each brush rod 7 being located between each pair of adjacent fins.

[0040] In practice, the brush rod 7 consists of a rod body and a soft brush mounted on the rod body. The soft brush contacts the fins, and when it moves, it can brush off the dust on the fins without damaging them.

[0041] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] Additionally, "multiple" refers to two or more.
