Description

Technical Field

[0001] This invention relates to the field of power detection device technology, and specifically to a power detection device with good heat dissipation. Background Technology

[0002] Power monitoring devices are key equipment for ensuring the safe and stable operation of power systems. They are mainly used to monitor parameters such as voltage, current, power, and power quality in the power system in real time and to provide early warnings of potential faults. Their working principle involves collecting power signals through sensors such as current transformers and voltage transformers, then performing signal conditioning and analog-to-digital conversion. Digital signal processing technology is then used to analyze and process the data, ultimately displaying the results or uploading them to a monitoring system. In practical applications, these devices are widely deployed in substations, distribution rooms, and industrial electrical equipment. Maintenance personnel can obtain power parameters through the device panel or a remote monitoring platform to promptly identify and resolve power anomalies.

[0003] However, the existing technology has the following problems:

[0004] As the integration of power detection devices continues to increase, the internal electronic components generate a lot of heat during long-term operation. Since traditional heat dissipation structures mostly use simple natural heat dissipation or single fan heat dissipation, they cannot dissipate the heat quickly and effectively, resulting in a continuous rise in internal temperature. High temperature environment will not only accelerate the aging of electronic components and reduce detection accuracy, but may also cause device failure, seriously affecting the safe and stable operation of the power system.

[0016] The beneficial effects are:

[0017] 1. This power detection device with excellent heat dissipation, through the cooperation of air-cooling and heat dissipation components, enables the fan to promote air circulation inside the casing. After heat is absorbed by multiple fixed plates, the air dissipates the heat from the casing through contact with the air. The multiple pairs of oscillating plates can absorb part of the heat from the fixed plates they are connected to, and promote heat dissipation through opening and closing motion. When the multiple pairs of oscillating plates open and close, they can also continuously fan the air near the multiple fixed plates, increasing the contact area between the fixed plates and the air, thereby promoting heat dissipation at the fixed plates and accelerating the heat dissipation efficiency.

[0018] 2. This power detection device with good heat dissipation effect has multiple pairs of swing plates that open and close to promote the lateral flow of air inside the shell, while the two baffles swing up and down to promote the longitudinal flow of air inside the shell. This allows the air inside the shell to come into more even contact with various parts of the shell during circulation, thereby carrying away the heat from various parts of the shell and achieving a good heat dissipation effect.

[0019] 3. This power detection device with excellent heat dissipation, through the setting of water-cooled components, allows the push roller and the elastic tube to cooperate to enable the coolant to circulate. When external air enters the housing, when the air comes into contact with the fan, the coolant in the fan can absorb some of the heat in the air, reduce the air temperature, thereby improving the air's ability to absorb heat from the housing, and further enhancing the heat dissipation effect.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] Example 1

[0036] Please see Figure 1 - Figure 6 A power detection device with good heat dissipation includes a housing 1 and a detector 2 installed inside it, and also includes an air-cooling component 4 for air cooling. The air-cooling component 4 includes a motor 41, which is installed inside the housing 1. The output end of the motor 41 is fixedly connected to a transmission wheel 42. A mounting base 44 is fixedly installed inside the housing 1. A fan 45 is rotatably connected to the inner wall of the mounting base 44. A belt 43 drives the fan 45 and the transmission wheel 42. Heat dissipation vents 3 are installed on both sides of the housing 1. After the motor 41 starts, it drives the transmission wheel 42 to rotate. The transmission wheel 42 drives the fan 45 to rotate on the mounting base 44 through the belt 43. When the fan 45 rotates, it can drive the airflow, so that the air enters from the heat dissipation vent 3 near the fan 45 and is discharged from the heat dissipation vent 3 away from the fan 45. The external air continuously passes through the inside of the housing 1, thereby taking away the heat inside the housing 1 and achieving the effect of air cooling.

[0037] Furthermore, a heat dissipation component 5 is used to accelerate the heat dissipation of the detector 2. The heat dissipation component 5 includes a heat-conducting plate 51, which is fixedly connected to the bottom of the detector 2. Two sets of fixing plates 52 are fixedly connected to the heat-conducting plate 51. Each set of fixing plates 52 includes multiple pairs of fixing plates 52, and multiple pairs of swing plates 510 are rotatably connected to each pair of fixing plates 52. The heat-conducting plate 51 can absorb the heat inside the detector 2. The heat-conducting plate 51, the fixing plates 52, and the swing plates 510 are all made of materials with high thermal conductivity. The two sets of fixing plates 52 can absorb the heat of the heat-conducting plate 51, and there are gaps between the multiple pairs of fixing plates 52. When air flows over the surface of the two sets of fixing plates 52, it can contact the multiple pairs of fixing plates 52 and carry away the heat emitted by the fixing plates 52, thereby accelerating the heat dissipation efficiency of the detector 2.

[0038] Furthermore, the heat dissipation assembly 5 also includes a slider 54, which is slidably mounted inside the housing 1. A grooved rod 55 is fixedly connected to the slider 54, a cam 53 is fixedly connected to the transmission wheel 42, and a slide 56 is slidably connected to the heat conduction plate 51. A groove is provided on the grooved rod 55, and a roller is provided on the cam 53. The roller of the cam 53 is slidably connected to the groove of the grooved rod 55. When the cam 53 rotates, the roller can convert the rotation into reciprocating motion through the cooperation with the groove. The slide 56 is fixedly connected to the slider 54. When the cam 53 rotates, it drives the grooved rod 55 to move back and forth reciprocally through the roller. The grooved rod 55 drives the slide 56 to move back and forth reciprocally through the slider 54. A second connecting rod 59 is hinged to the swing plate 510, and a sliding column 58 is hinged between the second connecting rods 59 on a pair of swing plates 510. The sliding column 58 is limited. It can only slide left and right. The sliding column 58 is slidably connected to the heat-conducting plate 51. The first connecting rod 57 is hinged on the sliding column 58 and is hinged to the slide frame 56. Taking one pair of swing plates 510 as an example, when the sliding column 58 moves back and forth, it can drive the two swing plates 510 to swing back and forth through the two second connecting rods 59, so that the two swing plates 510 continuously open and close. This allows multiple pairs of swing plates 510 below the heat-conducting plate 51 to continuously open and close. The multiple pairs of swing plates 510 can absorb part of the heat from the fixed plate 52 connected to them and promote the dissipation of heat through the opening and closing motion. When the multiple pairs of swing plates 510 open and close, they can also continuously fan the air near the multiple fixed plates 52, increase the contact area between the fixed plate 52 and the air, thereby promoting the dissipation of heat at the fixed plate 52 and accelerating the heat dissipation efficiency.

[0039] In addition, please see Figure 4 - Figure 7 The heat dissipation assembly 5 also includes two baffles 511 and two triangular blocks 512. The two baffles 511 are hinged inside the housing 1 and are mirror images of each other. The two triangular blocks 512 are fixedly connected to the slide 56. When the two triangular blocks 512 move, they slide in contact with the two baffles 511 respectively. When the two triangular blocks 512 slide in contact with the two baffles 511, they use their inclined surfaces to lift the two baffles 511. When the two triangular blocks 512 are not in contact with the two baffles 511, the two baffles 511 reset by gravity, causing the two baffles 511 to swing up and down, thereby promoting the longitudinal flow of air inside the housing 1. This allows the air inside the housing 1 to contact various parts of the housing 1 more evenly during the flow, thereby carrying away the heat from various parts of the housing 1.

[0040] It is worth noting that, please refer to Figure 2 , Figure 8 - Figure 12The water-cooling component 6 is used to further improve the heat dissipation effect of the air-cooling component 4. The water-cooling component 6 includes a first liquid pipe 61, a heat dissipation pipe assembly 62, a second liquid pipe 63, an elastic pipe 64, and a third liquid pipe 65. The first liquid pipe 61, the heat dissipation pipe assembly 62, the second liquid pipe 63, and the third liquid pipe 65 are all fixedly installed in the housing 1 by mounting components. The elastic pipe 64 is fixedly connected between the second liquid pipe 63 and the third liquid pipe 65. The heat dissipation pipe assembly 62 is provided with an inlet and an outlet. One end of the first liquid pipe 61 is connected to the mounting base 44. The other end of the first liquid pipe 61 is connected to the inlet of the heat pipe assembly 62. The end of the second liquid pipe 63 away from the elastic tube 64 is connected to the outlet of the heat pipe assembly 62. The end of the third liquid pipe 65 away from the elastic tube 64 is rotatably connected to the fan 45 through a connector. The first liquid pipe 61, the heat pipe assembly 62, the second liquid pipe 63, the elastic tube 64, the third liquid pipe 65, the first flow channel 66 and the second flow channel 67 are filled with coolant. The heat pipe assembly 62 is provided with multiple serpentine heat pipes, which can promote the dissipation of heat from the internal coolant, thereby reducing the temperature of the coolant.

[0041] It is worth mentioning that the fan 45 includes a central shaft, multiple fan blades, and an annular ring. The multiple fan blades are all mounted on the central shaft, and the annular ring is connected to the ends of the multiple fan blades furthest from the central shaft. A first flow channel 66 is provided between the central shaft, the multiple fan blades, and the annular ring. The first flow channel 66 communicates with the interior of the third liquid pipe 65. A second flow channel 67 is provided inside the mounting base 44, communicating with the first flow channel 66 and also communicating with the interior of the first liquid pipe 61. Air entering the housing 1 first contacts the fan 45. The fan 45 utilizes its internal coolant to absorb heat from the air, thus cooling the air.

[0042] It is worth noting that the water-cooling assembly 6 also includes a mounting bracket 68, two support rods 69, a push roller 610, and an arc-shaped block 611. The mounting bracket 68 is fixedly mounted on the slider 54. Both support rods 69 are hinged to the mounting bracket 68. The push roller 610 is rotatably mounted between the two support rods 69. A ratchet and pawl mechanism is provided inside the connection between the push roller 610 and the two support rods 69. The push roller 610 is subject to unidirectional limiting by the ratchet and pawl, which is a conventional unidirectional rotation limiting structure. The specific principles and structure are not detailed here. The arc-shaped block 611 is fixedly connected to the slider 54. The elastic tube 64 is located between the push roller 610 and the arc-shaped block 611. There is a large friction between the push roller 610 and the elastic tube 64. A spring 612 is connected between the support rod 69 and the mounting bracket 68. The elastic tube 64 is elastic. The springs 612 on the two support rods 69 can keep the push roller 610 in contact with the elastic tube 64. When the push roller 610 moves closer to the third liquid tube 65, the push roller 610 is pushed... Roller 610 cannot rotate, and the two support rods 69 swing downwards due to the friction between the push roller 610 and the elastic tube 64, causing the two support rods 69 to support the push roller 610 downwards. The push roller 610 squeezes the elastic tube 64, causing it to deform. During this process, the arc block 611 abuts against the lower part of the deformed position of the elastic tube 64, thereby achieving the effect of flattening the contact part between the elastic tube 64 and the push roller 610. When the push roller 610 moves closer to the third liquid tube 65, it pushes the coolant in the elastic tube 64 towards the third liquid tube 65. When the push roller 610 moves closer to the second liquid tube 63, it can roll along the outer wall of the elastic tube 64 without causing the elastic tube 64 to deform. This achieves the technical effect that the coolant can circulate in the first liquid tube 61, the heat dissipation tube group 62, the second liquid tube 63, the elastic tube 64, the third liquid tube 65, the first flow channel 66, and the second flow channel 67.

[0043] With the above structure, the working principle of this case is as follows: after the motor 41 starts, it drives the transmission wheel 42 to rotate. The transmission wheel 42 drives the fan 45 to rotate on the mounting base 44 through the belt 43. When the fan 45 rotates, it can drive the air flow, so that the air enters from the heat dissipation port 3 near the fan 45 and is discharged from the heat dissipation port 3 away from the fan 45. The external air continuously passes through the inside of the housing 1, thereby taking away the heat inside the housing 1 and achieving the effect of air cooling. The heat conduction plate 51 can absorb the heat inside the detector 2. The heat conduction plate 51, the fixed plate 52 and the swing plate 510 are all made of materials with high thermal conductivity. The two sets of fixed plates 52 can absorb the heat of the heat conduction plate 51, and there are gaps between the multiple pairs of fixed plates 52. When the air flows over the surface of the two sets of fixed plates 52, it can contact the multiple pairs of fixed plates 52 and take away the heat emitted by the fixed plates 52, thereby accelerating the heat dissipation efficiency of the detector 2.

[0044] When the transmission wheel 42 rotates, it drives the cam 53 to rotate. When the cam 53 rotates, the roller can convert the rotation into reciprocating motion through the cooperation of the slide groove. This causes the cam 53 to drive the groove rod 55 to move back and forth reciprocally through the roller. The groove rod 55 drives the slider 54 to move back and forth reciprocally. The slider 54 drives the slide 56 to move back and forth reciprocally. The slide column 58 is limited and can only slide left and right. When the slide 56 moves back and forth, it can drive multiple slide columns 58 to move horizontally reciprocally through multiple first connecting rods 57. The slide 56 is located between two rows of fixed plates 52. The multiple slide columns 58 are located on the side of multiple pairs of fixed plates 52 closest to the slide 56. Taking the oscillating plate 510 as an example, when the sliding column 58 moves back and forth, it can drive the two oscillating plates 510 to oscillate back and forth through the two second connecting rods 59, so that the two oscillating plates 510 continuously open and close. This allows the multiple pairs of oscillating plates 510 below the heat-conducting plate 51 to continuously open and close. The multiple pairs of oscillating plates 510 can absorb part of the heat from the fixed plate 52 connected to them, and promote the dissipation of heat through the opening and closing motion. When the multiple pairs of oscillating plates 510 are opening and closing, they can also continuously fan the air near the multiple fixed plates 52, increase the contact area between the fixed plate 52 and the air, thereby promoting the dissipation of heat at the fixed plate 52 and accelerating the heat dissipation efficiency.

[0045] When the carriage 56 moves back and forth, it drives the two triangular blocks 512 to move back and forth as well. During the movement, the two triangular blocks 512 slide into contact with the bottom of the two spoilers 511, so that the two triangular blocks 512 use their inclined surfaces to lift the two spoilers 511. When the two triangular blocks 512 are not in contact with the two spoilers 511, the two spoilers 511 return to their original position by gravity. This allows the carriage 56 to swing up and down with the two spoilers 511 as it moves back and forth. The opening and closing motion of the multiple pairs of swing plates 510 can promote the lateral flow of air inside the shell 1, while the up and down swing of the two spoilers 511 can promote the longitudinal flow of air inside the shell 1. This allows the air inside the shell 1 to contact all parts of the shell 1 more evenly during the flow, thereby carrying away the heat from all parts of the shell 1.

[0046] Coolant is contained in the first liquid pipe 61, the heat dissipation pipe assembly 62, the second liquid pipe 63, the elastic pipe 64, the third liquid pipe 65, the first flow channel 66, and the second flow channel 67. When the slider 54 moves back and forth, it drives the mounting frame 68 to move back and forth. The mounting frame 68 drives the push roller 610 to move back and forth via two support rods 69. The springs 612 on the two support rods 69 can keep the push roller 610 in contact with the elastic pipe 64. The elasticity of the springs 612 is small, so that the push roller 610 only keeps in contact with the elastic pipe 64 without causing deformation of the elastic pipe 64. When the push roller 610 moves back and forth, it is unidirectionally limited by the ratchet pawl. There is a large frictional force between the push roller 610 and the elastic tube 64. Therefore, when the push roller 610 moves closer to the second liquid tube 63, it can roll along the outer wall of the elastic tube 64 without causing deformation of the elastic tube 64. When the push roller 610 moves closer to the third liquid tube 65, it cannot rotate, and the two support rods 69 swing downward due to the frictional force between the push roller 610 and the elastic tube 64. This causes the two support rods 69 to support the push roller 610 downward, and the push roller 610 squeezes the elastic tube 64, causing it to deform. During this process, the arc-shaped block 611 abuts against the area below the deformation position of the elastic tube 64, thereby achieving elasticity. The contact area between tube 64 and push roller 610 is flattened. When push roller 610 moves closer to the third liquid tube 65, it pushes the coolant in elastic tube 64 towards the third liquid tube 65. When push roller 610 moves closer to the second liquid tube 63 again, it rolls again, and the two support rods 69 no longer support push roller 610 downwards. Elastic tube 64 returns to its original position due to its own elasticity. When push roller 610 moves closer to the second liquid tube 63, the coolant in elastic tube 64 does not flow. This achieves the effect of coolant flowing through the first liquid tube 61, heat dissipation tube assembly 62, second liquid tube 63, elastic tube 64, third liquid tube 65, first flow channel 66, and... The circulating flow in the second channel 67 ensures that the air entering the housing 1 first comes into contact with the fan 45. The fan 45 uses its internal coolant to absorb heat from the air and cool it down, allowing the air to absorb more heat after entering the housing 1. When the coolant flows through the heat dissipation pipe assembly 62, which is equipped with multiple serpentine heat dissipation pipes, it promotes the dissipation of heat from the internal coolant, thereby reducing the temperature of the coolant and maintaining the heat exchange effect of the coolant. This prevents the air entering the housing 1 from being too hot due to the high external air temperature when used in high-temperature environments, which would affect heat dissipation and result in poor heat dissipation.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
