Description

Technical Field

[0001] The present invention relates to the technical field of voltage stabilizers, and in particular to a voltage stabilizer and a heat dissipation method thereof. Background Art

[0002] A voltage stabilizer is a device that can adjust and control the voltage to stabilize the output voltage. Since the voltage stabilizer is a device that adjusts the voltage, it will generate heat during operation. In the prior art, in order to ensure the stable and efficient operation of the voltage stabilizer, a heat dissipation structure is usually provided to dissipate the heat of the voltage stabilizer.

[0003] However, the heat dissipation structure of the current voltage regulator is too common, which is mainly reflected in the following aspects: 1. The existing heat dissipation structure will set heat dissipation holes on the surface of the heat dissipation structure to increase the heat dissipation effect. However, this also increases the probability of foreign objects contacting the voltage stabilizer, making the voltage stabilizer more affected by external factors, such as being damaged by birds and other species. If the heat dissipation holes are appropriately reduced, the heat dissipation effect will be affected. Therefore, the two cannot be achieved at the same time.

[0004] 2. When dissipating heat for the voltage stabilizer, the existing heat dissipation structure mainly dissipates heat for the exposed part of the voltage stabilizer, but is unable to dissipate heat for the bottom of the voltage stabilizer, thus resulting in a defect of poor heat dissipation effect.

[0005] In summary, improvements need to be made. Summary of the invention

[0014] Preferably, a cleaning brush is provided on the split body.

[0015] In addition, the present invention also provides a heat dissipation method for a voltage regulator, which uses the above-mentioned voltage regulator structure. The present invention can control the drainage structure to dissipate heat for the voltage regulator body in the first mode or the second mode according to the heating state of the voltage regulator body; In the first mode, the following steps are included: a1: The second electromagnet is powered off, and the drainage body is controlled by the fourth return spring to open the upper air inlet and close the second heat dissipation port; a2: The airflow is sent into the upper chamber from the air supply pipe and the upper air inlet.

The airflow in the air supply pipe can lift the telescopic block and the annular lifting platform from the lower air inlet, and cause the airflow to flow in the lower cavity to dissipate heat at the bottom of the stabilizer.

[0016] Preferably, when the annular lifting platform is lifted, the stabilizer body rises and the gap between the stabilizer body and the inner wall of the upper cavity is reduced to increase the flow velocity of the airflow in the upper cavity.

[0017] The present invention has at least the following beneficial effects: 1. The voltage stabilizer body of the present invention is arranged in a protective body, and the voltage stabilizer body is protected by the protective body to prevent the voltage stabilizer body from being damaged. In addition, the protective body of the present invention also has heat dissipation. That is to say, when dissipating heat, the protective body switches to a heat dissipation position, so that the heat generated by the operation of the voltage stabilizer can be effectively discharged. In the heat dissipation position, the heat dissipation channel formed between the parts can prevent species with a certain volume such as birds from entering, thereby also protecting the voltage stabilizer body.

[0018] 2. In order to improve the heat dissipation effect of the present invention, a drainage structure is arranged in the protective body. Under the control of the drainage structure, the protective body of the present invention can dissipate heat for the voltage stabilizer in the first mode and the second mode. The first mode is a normal mode, which can stably dissipate heat for the voltage stabilizer body. The second mode is an efficient heat dissipation mode. Compared with the first mode, the heat dissipation effect of the second mode is more prominent.

[0019] 3. Based on point 2, the present invention can not only improve the heat dissipation effect but also improve the heat dissipation efficiency in the second mode, that is, by lifting the stabilizer body, the active gap of the airflow is reduced, thereby increasing the flow rate of the airflow and further improving the heat dissipation efficiency.

[0020] 4. In addition, when the present invention dissipates heat, the split body outside the voltage stabilizer body can be controlled to move around the voltage stabilizer, thereby guiding the exhausted hot air to flow outward to avoid affecting the heat dissipation.

[0021] In addition, other advantages of the present invention will be shown in the embodiment of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1 like Figure 1-Figure 4 As shown, the present invention discloses a voltage stabilizer, including a voltage stabilizer body 1a. In this embodiment, it also includes a protective body for accommodating the voltage stabilizer body, and the protective body includes: The inner body 10 has a heat dissipation cavity 10a for accommodating the stabilizer body 1a; The outer body 11 is composed of a plurality of separate bodies 110 hingedly mounted on the inner body 10; Wherein, each split body 110 can be controlled to switch between a protection posture and a heat dissipation posture; In the protective position, each of the sub-bodies 110 rotates at the hinge and contacts each other to form a protective layer located outside the inner body 10; In the heat dissipation posture, each split body 110 rotates at the hinge and separates from each other, and a heat dissipation channel 20 for air flow to enter the inner body 10 or for air flow to be discharged from the inner body 10 is formed between adjacent split bodies 110 .

[0026] In this embodiment: the inner body 10 includes: The body 100 is open at the bottom and is provided with a heat dissipation cavity 10a for accommodating the voltage stabilizer body 1a; A mounting plate 101 is detachably connected to the body 100 via bolts; An air supply pipe 102 is embedded in the body 100 and is capable of supplying air to the heat dissipation cavity 10a; A plurality of heat dissipation ports 103 (the diameter of the heat dissipation ports is set according to the different sizes of the voltage regulators, and therefore is not limited in this embodiment) are distributed on the body 100 and communicated with the heat dissipation cavity 10a, and are provided with a filter 103a.

[0027] In this embodiment: the outer body 11 includes: The support base 111 is fixedly disposed on the main body 100; The split body 110 is rotatably mounted on the support base 111 via a hinge shaft 112; The driven gear 113 is mounted on the hinge shaft 112; The transmission gear 114 is rotatably disposed on the body 100 and meshes with each driven gear 113; The transmission gear 114 can be controlled by the motor 115 to rotate clockwise or counterclockwise. When the transmission gear 114 rotates clockwise, the split body 110 is controlled to switch to the protection position; when the transmission gear 114 rotates counterclockwise, the split body 110 is controlled to switch to the heat dissipation position.

[0028] refer to Figure 1-Figure 4 In this embodiment, when protecting the voltage stabilizer, the external body can be switched to a protection position (refer to Figure 3 ), in the protection position, the parts are in contact with each other and protect the inner body. When cooling, the outer body is switched to the cooling position (reference Figure 4 ), when in the heat dissipation position, the split parts are unfolded, and the heat dissipation port can be connected with the heat dissipation channel formed between the split parts. Therefore, when the air supply pipe supplies air into the heat dissipation cavity, the heat can be discharged from the heat dissipation port to complete the heat dissipation work.

[0029] Embodiment 2 is different from Embodiment 1 in that: refer to Figure 5-Figure 8 In this embodiment, the support seat 111 is slidably arranged on the main body 100, and also includes an electromagnetic structure. The electromagnetic structure is arranged on the support seat 111 and can brake the support seat 111 or the driven gear 113. That is to say, the main body 100 is provided with an annular sliding groove 30 for the support seat 111 to slide. The electromagnetic structure of this embodiment is used to brake the support seat 111 and the hinge shaft 112, and the purpose of braking the driven gear 113 is achieved by braking the hinge shaft 112. That is to say, the electromagnetic structure of this embodiment includes:

[0030] The electromagnet 40 has a first electromagnet 41 therein and is installed in the support seat 111; The brake groove is composed of a first brake groove 401 and a second brake groove 402 provided on the electromagnet 40; The brake block is composed of a first brake block 43 slidably connected to the first brake groove 401 and a second brake block 44 slidably connected to the second brake groove 402; The return spring is composed of a first return spring 45 and a second return spring 46 respectively arranged in the first braking groove 401 and the second braking groove 402; Wherein, the first brake block 43 is provided with a first magnet 431 with a magnetic pole opposite to that of the first electromagnet 41; When the first electromagnet 41 is energized and generates magnetism, the first brake block 43 moves away from the first electromagnet 41 due to the repulsion between the magnetic poles of the first magnet 431 and the first electromagnet 41. When the first brake block 43 moves away from the first electromagnet and contacts the groove wall of the annular sliding groove 30, it limits the sliding of the support seat in the annular sliding groove 30, and the second brake block 44 is attracted by the first electromagnet 41 and moves close to the first electromagnet 41, thereby separating from the hinge shaft 112, allowing the hinge shaft 112 to rotate. Conversely, when the first electromagnet is de-energized, the first brake block 43 is driven by the first return spring 45 to separate from the annular sliding groove 30, and the second brake block is driven by the second return spring 46 to abut against the hinge shaft 112, thereby allowing the support seat to slide in the annular sliding groove 30 and limit the rotation of the hinge shaft.

[0031] In this embodiment: a telescopic groove 50 is formed on the mounting plate 101, and a telescopic block 52 is connected in the telescopic groove 50 through a third return spring 51, and an annular lifting platform 53 connected to the telescopic block 52 and for mounting the voltage stabilizer body 1a is provided in the heat dissipation cavity. When the voltage stabilizer body 1a is mounted on the annular lifting platform 53, the voltage stabilizer body 1a and the annular lifting platform 53 divide the heat dissipation cavity into an upper cavity 61 and a lower cavity 62; The main body 100 is formed with a lower air inlet 63 that can be opened and closed by the telescopic block 52 and communicated between the air supply pipe 102 and the lower chamber 62, and an upper air inlet 64 that can be opened and closed by the drainage structure and communicated between the air supply pipe 102 and the upper chamber 61; The heat dissipation opening 103 is composed of a first heat dissipation opening 1031 which is normally open and a second heat dissipation opening 1032 which can be opened and closed by the drainage structure. The first heat dissipation opening 1031 and the second heat dissipation opening 1032 are longitudinally staggered. The drainage structure has at least a first mode and a second mode and a drainage end that can be controlled by a motor 115; In the first mode, the drainage structure controls the upper air inlet 64 to be opened and the second heat dissipation port 1032 to be closed, and the air supply pipe 102 supplies air from the upper air inlet 64 to the upper cavity 61, and the air flows from the top of the stabilizer body 1a from top to bottom, and dissipates the heat of the stabilizer body 1a and is discharged from the first heat dissipation port 1031; In the second mode, the drainage structure controls the upper air inlet 64 to close and the second heat dissipation port 1032 to open. The drainage end is controlled by the motor 115 to rotate through the first heat dissipation port 1031 to introduce air into the upper cavity 61, and dissipates the heat of the regulator body 1a and then discharges it from the second heat dissipation port 1032, causing negative pressure to form in the upper cavity 61. The air supply pipe 102 supplies air from the lower air inlet 63 and lifts the telescopic block 52 to send the air flow to the lower cavity 62 and discharge it from the exhaust port 62a.

[0032] In this embodiment: the drainage structure includes: The annular fixing plate 70 is installed in the upper cavity 61 and is located between the first heat dissipation opening 1031 and the second heat dissipation opening 1032; The guide body 71 is mounted on the annular fixing plate 70 through a fourth return spring 72; The driven shaft 73 is rotatably disposed on the drainage body 71; The drainage fan 74 is mounted on the driven shaft 73; The second electromagnet 75 is installed in the heat dissipation cavity 10a (located at the top of the heat dissipation cavity 10a), and attracts the drainage body 71 to move toward the transmission gear 114 when powered on; The guide body 71 is provided with a lifting portion 71a, and the lifting portion 71a has a connecting port 71b that can be connected with the second heat dissipation port 1032 or the upper air inlet 64; One end of the driven shaft 73 longitudinally penetrates the guide body 71 , and a limiting structure is provided between the driven shaft 73 and the transmission gear.

[0033] In this embodiment: the limiting structure includes: The limiting body 80 is connected to the transmission gear through the transmission shaft 81; The matching body 82 is integrally formed and arranged on the driven shaft 73; Among them, a side of the limiting body 80 close to the matching body 82 is recessed with a matching groove 83 adapted to the matching body 82, and a limiting rib 84 and a limiting groove 85 adapted to each other are respectively provided on the side wall of the matching body 82 and the groove wall of the matching groove 83.

[0034] In this embodiment: a cleaning brush 9 is provided on the split body 110 .

[0035] refer to Figure 5-Figure 8 , the principle of this embodiment is: In the first mode, the second electromagnet is powered off, the connecting port of the lifting part on the drainage body is connected to the upper air inlet, and the second heat dissipation port is closed. At this time, the air supply pipe sends the airflow from the upper air inlet into the upper cavity (the area between the annular fixing plate and the drainage body), the airflow passes through the annular fixing plate and dissipates the heat of the stabilizer from top to bottom, and is discharged from the first heat dissipation port after the heat dissipation is completed, completing the heat dissipation work of the first mode.

[0036] In the second mode, the second electromagnet is energized and generates magnetism, the drainage body is attracted to rise, and the connecting port of the lifting part is connected with the second heat dissipation port, and the upper air inlet is closed at the same time (so that the air supply pipe cannot send the airflow to the heat dissipation cavity through the upper air inlet). At the same time, the matching body and the limiting body of the limiting structure cooperate with each other. When the motor drives the transmission gear to rotate, the driven shaft can be controlled to rotate through the limiting mechanism, and the drainage fan is rotated. When the drainage body rises, the drainage enters the annular port of the annular fixing plate. When the drainage fan is started, the airflow below the annular fixing plate can be transported to the upper area of ​​the annular fixing plate and discharged through the second heat dissipation port, so that a negative pressure is formed in the upper cavity. The formed negative pressure allows the inner body to introduce the airflow from the first heat dissipation port into the upper cavity, thereby completing the heat dissipation of the stabilizer. At the same time, the airflow in the air supply pipe will enter the lower cavity through the lower air inlet, and lift the telescopic block and the annular lifting platform, so that the air supply pipe and the lower cavity are interconnected, and the bottom of the stabilizer is cooled when the airflow passes through the lower cavity, and the airflow is discharged through the exhaust port to complete the heat dissipation work.

[0037] Therefore, this embodiment can improve the heat dissipation effect of the voltage stabilizer through the second mode, especially can dissipate the heat of the bottom of the voltage stabilizer, which is not available in the prior art. In the prior art, the bottom of the voltage stabilizer is placed on a carrier, so the heat generated at the bottom often cannot be effectively discharged. However, the protective body provided in this embodiment can comprehensively dissipate the heat of the voltage stabilizer and ensure the use of the voltage stabilizer.

[0038] Worthy of mention are: In this embodiment (refer to Figure 7 ), the first heat dissipation port and the second heat dissipation port of this embodiment are staggered, so that the heat dissipation channels formed between adjacent split bodies can correspond to the first heat dissipation port and the second heat dissipation port respectively, that is, adjacent heat dissipation channels correspond to one of the first heat dissipation port and the second heat dissipation port respectively. Therefore, when the first heat dissipation port takes in air and the second heat dissipation port exhausts air, it is avoided that the exhausted hot air is reintroduced from the first heat dissipation port into the heat dissipation cavity.

[0039] Secondly, in this embodiment, an electromagnetic structure is provided on the support seat, and the electromagnetic structure can be used to enable the motor to control the movement of the split body in different forms, such as: when the first electromagnet of the electromagnetic structure is energized, the first brake block is controlled to brake the support block to fix the support block, and the second brake block is separated from the hinge shaft, so that the hinge shaft can rotate normally. In this mode, the motor can drive the split body to switch between the protection posture and the heat dissipation posture through the transmission gear and the driven gear, and when the first electromagnet of the electromagnetic structure is de-energized, the hinge shaft is restricted from rotating by the second brake block, and the support seat can move in the annular sliding groove. Therefore, the motor can drive the support seat to rotate around the inner body through the transmission gear and the driven gear, and drive the split body to rotate; In the protection position, when the split body rotates, the cleaning brush on the split body is used to clean the filter screens at the first heat dissipation port, the second heat dissipation port and the exhaust port to ensure that the air flow can be normally introduced into the inner body during heat dissipation; In the heat dissipation position, when the split body rotates, the split body can guide the hot air discharged from the second heat dissipation port in a direction away from the inner body, thereby reducing the probability of the just-discharged hot air being reintroduced into the inner body, thereby ensuring the heat dissipation effect.

[0040] Third, in this embodiment, when the upper chamber's drainage fan controls the generation of airflow to form a negative pressure, the air supply pipe can more easily lift the pressure regulator, so that the gas can smoothly enter the lower chamber; at the same time, when the pressure regulator (i.e., the pressure regulator body of this embodiment) is lifted, the gap between the pressure regulator and the annular fixed plate is reduced. Therefore, when the drainage fan maintains the same rotation speed, the flow rate of the airflow in the upper chamber is increased, thereby increasing the frequency of the airflow entering from the first heat dissipation port, thereby improving the heat dissipation efficiency of the pressure regulator.

[0041] It should be noted that the number of air supply pipes in this embodiment is not limited to one. In other embodiments, a corresponding number of air supply pipes may be added according to appropriate circumstances for better heat dissipation, and the air supply pipes may be distributed circumferentially and equidistantly in the body, so that air can be supplied to the heat dissipation cavity from multiple directions to ensure the heat dissipation effect. In other words: A single air supply pipe can be inserted into the main body from the bottom of the main body (that is, a chamber for installing the air supply pipe is formed on the inner wall of the main body, and the outer wall of the air supply pipe is sealed and fits with the chamber as a whole), and an opening connected to the upper air inlet and the lower air inlet is reserved on the air supply pipe to realize air supply to the heat dissipation cavity through the upper air inlet or the lower air inlet, and there can be multiple such air supply pipes, which are circumferentially spaced and distributed in the inner wall of the main body.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
