Description

Technical Field

[0001] This invention relates to the field of heat dissipation in televisions, and more particularly to a high-precision adaptive heat dissipation temperature control device for LCD televisions. Background Technology

[0002] During use, televisions generate heat from their electronic components. Most televisions dissipate heat through solid-state conduction, while some use cooling fans for air exchange. However, over time, the ventilation holes in televisions easily become clogged with dust, leading to poor heat dissipation. Chinese patent application number CN202020325691.3 describes a television cooling device that uses a rope pulled manually to move a movable rod downwards to scrape dust off a filter. A storage compartment allows for convenient centralized dust collection. Compared to existing technologies, this device is multifunctional and easy to clean. However, it requires manual cleaning, which can be difficult due to the wall obstructing the rope pull when the television is placed close to it. Furthermore, the filter needs regular manual cleaning, making television maintenance inconvenient.

[0003] Meanwhile, because the heat dissipation holes of the device are fixed, the heat dissipation position of the TV is singular, the heat dissipation area is small, the heat dissipation takes a long time to diffuse after encountering the wall, and the heat dissipation holes are more likely to be blocked by dust and impurities when they cannot be rotated. Summary of the Invention

[0004] To overcome the shortcomings of existing devices, such as the difficulty of manually pulling ropes to clean dust, the inconvenience of requiring regular manual cleaning and maintenance of the filter, and the fixed state of the heat dissipation holes, which results in a single heat dissipation location and a small heat dissipation area, and makes the heat dissipation holes more susceptible to clogging by dust and impurities, this invention provides a high-precision adaptive heat dissipation temperature control device for LCD TVs.

[0005] Technical Solution: A high-precision adaptive heat dissipation and temperature control device for LCD TVs includes a loudspeaker, a fan, a first fin, and a second fin. Several loudspeakers are arranged inside the TV. A fan is installed inside the TV. A protrusion is provided behind the fan. Several rotating first fins for controlling air intake are connected to the inside of the TV. Several rotating second fins for controlling the heat dissipation direction of the TV are also connected to the inside of the TV. The device further includes a vibration assembly, a heat sink, a film, and a lifting rod. A vibration assembly to prevent dust adhesion is provided behind the TV. A heat sink to improve heat dissipation is connected to the vibration assembly. Several pressing parts are provided on the heat sink, and each second fin contacts an adjacent pressing part. A film to promote airflow is provided behind each loudspeaker. A lifting rod to increase the air intake of the TV is installed on several first fins, and the lifting rod engages with the protrusion.

[0006] Optionally, several second fins are arranged along the edge of the heat sink, and each second fin rotates in the direction of rotation toward the outside of the heat sink.

[0007] Optionally, the vibration assembly includes a first fixed plate, a second fixed plate, a first filter, a first connecting rod, a second filter, and a second connecting rod; the first fixed plate is fixedly connected to the rear side of the television; the second fixed plate is fixedly connected to the upper side of the first fixed plate; a first filter to prevent dust from entering the interior of the television is fixedly connected to the front side of the second fixed plate; a first connecting rod for transmitting vibration and shaking off dust is fixedly connected to the upper side of each loudspeaker, and each first connecting rod is in contact with the first filter; a second filter to prevent dust from entering the interior of the television is fixedly connected to the front side of the first fixed plate; a second connecting rod to prevent the air inlet of the television from being blocked is fixedly connected to the side of each loudspeaker facing the middle of the television, and each second connecting rod is in contact with the second filter.

[0008] Optionally, it also includes a copper sheet; a copper sheet is connected to the rear side of the second fixing plate to make the heat dissipation of the TV more uniform, and the copper sheet is in contact with the heat sink.

[0009] Optionally, a cleaner is also included; each second fin is slidably connected to a cleaner for scraping off dust adhering to the second fin.

[0010] Optionally, it also includes a diffuser plate; a diffuser plate is fixed to the rear of the television to prevent the television's heat dissipation vents and air inlets from being too close to the wall.

[0011] Optionally, a number of triangular cones are provided on the front side of the diffuser plate, with the upper triangular cone and the lower triangular cone interlocking, and a groove is formed between each pair of adjacent triangular cones.

[0012] Optionally, it also includes a waterproof membrane; a waterproof membrane is fixed to the upper side of the diffuser to prevent water from flowing into the interior of the television.

[0013] Optionally, a rectangular groove is provided on the upper front side of the diffuser plate to remove dust from the surface of the diffuser plate.

[0014] Alternatively, the waterproof membrane can be configured as an upwardly convex curved shape.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes that by driving the first fin to rotate through the lifting rod, the air intake area of ​​the fan is increased, thereby improving the heat dissipation effect of the television. The vibration of the loudspeaker causes the diaphragm to deform, creating airflow around the loudspeaker, which in turn helps to dissipate heat inside the television and further improves the television's heat dissipation effect. The second fins, which rotate in the direction of rotation towards the outside of the heat sink, better dissipate the heat in all directions, improve the heat dissipation effect of the TV, and at the same time prevent the heat from rushing directly towards the background wall, so that the heat can be better discharged. The dust adhering to the second fin is scraped off by the cleaner to prevent dust accumulation on the second fin and improve the heat dissipation of the TV. The triangular cones on the front of the diffuser plate make its surface uneven and conical, allowing sound to diffuse in different directions, avoiding sound focusing and improving the sound quality of the TV. At the same time, the grooves formed between adjacent triangular cones guide hotter air to flow out from the upper side of the diffuser plate, while outside air flows into the TV from the lower side, improving the heat dissipation of the TV. The rectangular grooves guide the gas to flow upwards and downwards, blowing away moisture and dust from the surface of the diffuser plate and preventing dust and moisture from affecting the sound amplification effect of the diffuser plate. The upward-convex curved shape of the waterproof membrane guides the upward airflow of the copper sheet downwards, further improving the effectiveness of the waterproof membrane in removing dust and moisture, thereby improving the sound quality of the television.

Detailed Implementation

[0018] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] Example 1 like Figures 3-8 As shown, a high-precision adaptive heat dissipation temperature control device for an LCD TV includes a loudspeaker 3, a fan 4, a first fin 6, and a second fin 7. Two loudspeakers 3 are arranged on the lower inner side of the TV 1. A fan 4 is installed on the lower inner side of the TV 1, and the fan 4 is located between two adjacent loudspeakers 3. A protrusion 4001 is provided on the rear side of the fan 4. Several first fins 6 are connected to the lower inner side of the TV 1. Several second fins 7 are connected to the middle inner side of the TV 1 through a torsion spring. It also includes a vibration assembly, a heat sink 2, a membrane 5, and a lifting rod 8; a vibration assembly is located on the lower rear side of the television set 1; the heat sink 2 is connected to the vibration assembly via a spring; the heat sink 2 is provided with several extrusion sections 2001, and each second fin 7 is in contact with an adjacent extrusion section 2001; a membrane 5 is provided on the rear side of each loudspeaker 3; a lifting rod 8 is mounted on several first fins 6, and the lifting rod 8 is fitted with a protrusion 4001; with a reference from rear to front, the fan 4 rotates clockwise to draw outside air into the television set 1, replacing the hotter air inside the television set 1, thus achieving the heat dissipation effect of the television set 1. During the rotation of the fan 4, the protrusion 4001 drives the lifting rod 8 to move downward first, and then upward. When the lifting rod 8 moves downward, it drives the first fins 6 to flip upward; when the lifting rod 8 moves upward, it drives the first fins 6 to flip downward. The rotation of the first fins 6 increases the air intake area of ​​the fan 4. To improve the heat dissipation of the television 1, the air intake changes during the rotation of the first fin 6. When the air intake increases, the heat sink 2 moves backward due to the impact of the gas. When the air intake is small, the spring on the heat sink 2 causes it to bounce back to its initial state, thus moving the heat sink 2 back and forth. When the heat sink 2 moves backward, it compresses the second fin 7 to rotate towards the center of the heat sink 2. When the heat sink 2 moves forward, the torsion spring returns the second fin 7 to its original position. The rotation of the second fin 7 increases the heat dissipation area of ​​the television 1. At the same time, the airflow generated by the rotation of the second fin 7, together with the fan 4, better dissipates heat from the television 1. During the operation of the loudspeaker 3, vibration is generated. The vibration of the loudspeaker 3 causes the diaphragm 5 to deform. The bulging generated by the deformation of the loudspeaker 3 drives the airflow, which in turn helps the outside gas to enter the interior of the television 1. At the same time, it allows the gas to circulate at the back of the television 1, dissipating heat from the television 1 and thus improving the heat dissipation effect of the television 1.

[0020] Several second fins 7 are arranged along the edge of the heat sink 2, and each second fin 7 rotates in the direction of rotation towards the outside of the heat sink 2. Through the rotation and heat dissipation process of the second fins 7, the heat is better dissipated to all sides, which improves the heat dissipation effect of the TV 1 and avoids the heat from rushing directly to the background wall, so that the heat is better discharged.

[0021] The vibration assembly includes a first fixed plate 101, a second fixed plate 102, a first filter 103, a first connecting rod 104, a second filter 105, and a second connecting rod 106. The first fixed plate 101 is fixedly connected to the lower rear side of the television set 1. The second fixed plate 102 is fixedly connected to the upper side of the first fixed plate 101. The first filter 103 is fixedly connected to the front side of the second fixed plate 102. Each loudspeaker 3 has a first connecting rod 104 fixedly connected to its upper side, and each first connecting rod 104 contacts the first filter 103. A second filter 105 is fixedly connected to the front side of the first fixed plate 101. Each loudspeaker 3 has a second connecting rod 106 fixedly connected to the side facing the center of the television set 1, and each second connecting rod 106 contacts the second filter 105. Due to the rotation of the first fin 6 and the second fin 7... The increased air intake and exhaust area of ​​the television set 1 makes it easier for dust to enter the interior of the television set 1. The first filter 103 intercepts dust in the air during the heat dissipation process of the television set 1, preventing dust from entering the interior of the television set 1 and ensuring the normal operation of the television set 1. The second filter 105 intercepts dust during the air intake process of the television set 1, preventing dust from entering the interior of the television set 1 through the air intake. At the same time, the vibration generated during the operation of the loudspeaker 3 is transmitted to the first filter 103 and the second filter 105 through the first connecting rod 104 and the second connecting rod 106. The vibration shakes off the dust attached to the first filter 103 and the second filter 105, preventing the first filter 103 and the second filter 105 from being blocked by dust accumulation, thereby increasing the air intake and heat dissipation area of ​​the television set 1.

[0022] It also includes a copper sheet 107; the copper sheet 107 is connected to the rear side of the second fixing plate 102 by a spring, and the copper sheet 107 is in contact with the heat sink 2; when the heat sink 2 moves backward, it pushes the copper sheet 107 open, so that the copper sheet 107 moves backward, and the heat dissipated from the heat sink 2 and the second fin 7 directly contacts the copper sheet 107. The properties of the copper sheet 107 material make the heat dissipation of the gas faster and more uniform. At the same time, because the copper sheet 107 is relatively thin, when the heat sink 2 returns to the initial position, the spring drives the copper sheet 107 to move forward. During the back and forth movement, the copper sheet 107 is deformed, and airflow is generated around the copper sheet 107, thereby dissipating the hot air more quickly.

[0023] Example 2 Based on Example 1, such as Figure 9 and Figure 10As shown, it also includes a cleaner 201; a cleaner 201 is slidably connected to each second fin 7; when the TV 1 is dissipating heat, the airflow spreads outwards along the front side of the heat sink 2 and then flows to the second fin 7, resulting in a weaker airflow around the second fin 7, causing dust to adhere to the second fin 7. Over time, this can easily clog the heat dissipation vents between two adjacent second fins 7. When the heat sink 2 moves backward, the squeezing part 2001 first pushes the cleaner 201 to slide on the second fin 7, scraping off the dust attached to the second fin 7, and then pushes the second fin 7 to flip towards the center of the heat sink 2, thereby shaking off the dust from the second fin 7 and improving the heat dissipation effect of the TV 1.

[0024] Example 3 Based on Examples 1 and 2, such as Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, it also includes a diffuser plate 301; the diffuser plate 301 is fixed to the rear side of the television set 1; during the placement of the television set 1, after the diffuser plate 301 is attached to the wall, the diffuser plate 301 is used to leave a gap between the air intake and heat dissipation vents on the back of the television set 1, so as to avoid the television set 1 being too close to the wall, which would cause the air intake and heat dissipation vents to be blocked and affect the heat dissipation of the television set 1. The diffuser plate 301 is used to make the sound emitted by the amplifier 3 diffuse more evenly, thereby improving the sound quality of the television set 1. At the same time, the diffuser plate 301 is used to support the rear side of the television set 1, so as to prevent the television set 1 from falling over due to the instability of the brackets on both sides.

[0025] Several triangular cones are arranged on the front side of the diffuser plate 301. The upper triangular cones and the lower triangular cones are interlocked, and a groove is formed between each pair of adjacent triangular cones. The triangular cones on the front side of the diffuser plate 301 make the surface of the diffuser plate 301 uneven, causing sound to reflect in different directions and avoiding sound focusing, thereby improving the sound quality of the television 1. At the same time, the grooves formed between each pair of adjacent triangular cones guide the hotter air to flow out better from the upper side of the diffuser plate 301. Since the fan 4 is on the lower side of the television 1, the outside air is guided by the diffuser plate 301 to flow into the television 1 from the lower side, forming a heat dissipation channel on the rear side of the television 1 and improving the heat dissipation effect of the television 1.

[0026] It also includes a waterproof plate 302; the waterproof plate 302 is fixedly attached to the upper side of the diffuser plate 301; since most living room background walls are made of smooth ceramic tiles, in southern regions, ceramic tiles are prone to producing a lot of water droplets, causing water droplets to enter the interior of the television 1 along the ceramic tile and the diffuser plate 301. The waterproof plate 302 seals the upper side of the diffuser plate 301, preventing water droplets from entering the interior of the television 1 through the diffuser plate 301, thus avoiding water damage to the television 1.

[0027] A rectangular groove 30101 is provided on the upper front side of the diffuser plate 301. When the copper sheet 107 moves backward, it pushes the gas in front of the copper sheet 107 toward the diffuser plate 301. The gas is blocked by the diffuser plate 301 and flows upward and downward in the rectangular groove 30101 respectively, thereby blowing away the moisture and dust on the surface of the diffuser plate 301 and preventing the dust and moisture from affecting the sound amplification effect of the diffuser plate 301.

[0028] The waterproof plate 302 is designed to be an upwardly convex curved shape. The upward airflow pushed by the copper sheet 107 is guided to flow downward through the curved waterproof plate 302, which further improves the dust and moisture removal effect of the waterproof plate 302, thereby improving the sound quality of the television 1.

[0029] 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 principles of the present invention should be included within the protection scope of the present invention.
