Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal televisions, in particular to a heat dissipation device for a liquid crystal television. Background Technique
[0002] A liquid crystal television is a television that uses liquid crystal technology as a display panel, uses a liquid crystal panel to generate images, and usually has a high definition and a thin body design.
[0003] Electronic components of a liquid crystal television, such as circuit boards, power modules, and backlight devices, will generate heat after long-term operation. Therefore, heat dissipation is required to keep the temperature within a stable and safe range. The heat dissipation windows promote air circulation, enabling heat to be more effectively transferred to the external environment. These windows are usually located on the back or side of the outer shell of the liquid crystal television to facilitate air flow, and are usually equipped with certain heat dissipation structures, such as ventilation holes or heat sinks, in the design.
[0004] However, natural heat dissipation cannot effectively meet the requirements in the case of larger-sized or high-power liquid crystal televisions, during long-term viewing, high-resolution content playback, etc., where more heat is generated. For this reason, we propose a heat dissipation device for a liquid crystal television to solve the existing problems. Content of the Utility Model
[0005] The purpose of the utility model is to propose a heat dissipation device for a liquid crystal television in view of the problems existing in the background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation device for a liquid crystal television, including a liquid crystal television housing, a sliding sleeve, and a diversion cover. Both ends of the liquid crystal television housing are provided with equally spaced heat dissipation holes. Filter meshes are arranged at both ends of the liquid crystal television housing. Sliding sleeves are sleeved at both ends of the liquid crystal television housing. A temperature sensor is arranged on the inner wall of the upper end of the liquid crystal television housing. A warning light is arranged on one side of the upper end of the liquid crystal television housing. A diversion cover is installed through the rear end of the liquid crystal television housing. A blower is arranged at the rear end of the liquid crystal television housing. A sealing sleeve is embedded in the diversion cover. A valve plate is slidably inserted into the sealing sleeve. Baffles are arranged symmetrically above the valve plate at the rear end of the liquid crystal television housing.
[0007] Preferably, the filter mesh covers and fits on the outer wall of one side of the heat dissipation hole. The gas flowing into the liquid crystal television housing through the heat dissipation hole is filtered by the filter mesh to remove the dust carried inside.
[0008] Preferably, guide rails are symmetrically arranged on both side edges at the two ends of the liquid crystal TV housing. Chutes are formed inside the front and rear ends of the sliding sleeve, and the chutes are slidably sleeved on the outer wall of the guide rail. By being slidably installed on the outer wall of the guide rail through the chute, the sliding sleeve is slidably guided at both ends of the liquid crystal TV housing.
[0009] Preferably, limit blocks are arranged at both the upper and lower ends of the liquid crystal TV housing. The limit blocks limit the upper and lower ends of the sliding sleeve to prevent the sliding sleeve from detaching from the outer wall of the liquid crystal TV housing.
[0010] Preferably, the suction end of the blower is communicated with the drainage cover. The suction force of the blower acts on the inside of the liquid crystal TV housing through the drainage cover.
[0011] Preferably, the upper end of the sealing sleeve penetrates through the drainage cover, and a handle is arranged at the upper end of the valve plate. The sealing sleeve inside the drainage cover slidably supports the valve plate, and the valve plate is grasped and lifted through the handle.
[0012] Preferably, the baffle plates are located on both sides above the valve plate, and magnetic blocks that magnetically attract each other are embedded and installed inside the lower ends of the baffle plates and the inner sides of the upper ends of both sides of the valve plate. The baffle plates limit the valve plate to prevent it from completely detaching from the sealing sleeve. When the upper end of the valve plate fits with the baffle plates, the valve plate is temporarily fixed through the magnetic attraction of the magnetic blocks.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. An additional gas channel is installed through the rear end of the liquid crystal TV housing in the present utility model. When the temperature inside the liquid crystal TV approaches the upper limit of the operating temperature, the valve plate is pulled upward to open the drainage cover, and the blower sucks the air flow inside the liquid crystal TV housing. Compared with the convective heat dissipation through the heat dissipation holes at both ends of the liquid crystal TV housing, the suction blower speeds up the discharge speed of the gas inside the liquid crystal TV housing, and at the same time speeds up the entry of the outside air into the liquid crystal TV housing, discharges the heat inside the liquid crystal TV housing and reduces the internal temperature.

Detailed implementation manners
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] As Figures 1 - 4 shown, a heat dissipation device for an LCD TV proposed by the present invention includes an LCD TV housing 1, a sliding sleeve 4, and a drainage cover 5. Heat dissipation holes 2 are provided at both ends of the LCD TV housing 1 at equal intervals. Filter screens 3 are provided at both ends of the LCD TV housing 1. The filter screens 3 cover and fit on the outer wall of one side of the heat dissipation holes 2. Sliding sleeves 4 are sleeved on both ends of the LCD TV housing 1. Guide rails 7 symmetrically distributed are provided on both sides of the edges at both ends of the LCD TV housing 1. Chute grooves are provided on the inner walls of the front and rear ends of the sliding sleeve 4, and the chute grooves are slidably sleeved on the outer wall of the guide rail 7. Limit blocks 6 are provided at both the upper and lower ends of the LCD TV housing 1.
[0022] Based on the implementation steps of Embodiment 1: When the LCD TV is running, internal components generate heat. The heat dissipation holes 2 allow air to flow through the internal components, and the hot air is forced to naturally discharge through the heat dissipation holes 2, thereby taking away the internal heat. During the air circulation process, the filter screen 3 filters the gas entering the inside of the LCD TV housing 1 through the heat dissipation holes 2, and the dust carried inside the gas is intercepted to prevent dust from entering the inside of the LCD TV housing 1.
[0023] During use, the filter screen 3 will gradually become blocked. Grasp the sliding sleeve 4 and move it up and down. The brush 13 on the inner wall of the sliding sleeve 4 contacts the filter screen 3, and the dust adhered to the filter screen 3 is brushed off to prevent the adhered dust from hindering the air from entering the inside of the LCD TV housing 1 and ensuring the effective inflow of gas.
[0024] As Figures 1 - 4As shown, a heat dissipation device for a liquid crystal television proposed by the present utility model, compared with the first embodiment, this embodiment further includes: a temperature sensor 14 is provided on the inner wall of the upper end of the liquid crystal television housing 1, a warning light 15 is provided on one side of the upper end of the liquid crystal television housing 1, a drainage cover 5 is installed through the rear end of the liquid crystal television housing 1, a fan 9 is provided at the rear end of the liquid crystal television housing 1, the suction end of the fan 9 is communicated with the drainage cover 5, a sealing sleeve 16 is embedded in the drainage cover 5, a valve plate 8 is slidably inserted into the sealing sleeve 16, the upper end of the sealing sleeve 16 penetrates through the drainage cover 5, a handle 12 is provided at the upper end of the valve plate 8, and baffles 10 are provided at the rear end of the liquid crystal television housing 1 and are symmetrically distributed above the valve plate 8. The baffles 10 are located on both sides above the valve plate 8, and magnetic blocks 11 that magnetically attract each other are embedded in the lower ends of the baffles 10 and the inner sides of both upper ends of the valve plate 8.
[0025] In this embodiment, the temperature sensor 14 monitors the temperature inside the liquid crystal television housing 1. Once the temperature exceeds the set threshold, the temperature sensor 14 will send a signal. Connect the temperature sensor 14 to a microcontroller or a processor. These chips can receive the signal from the temperature sensor 14 and perform corresponding operations. Write a program on the microcontroller or the processor to listen to the input of the temperature sensor 14. Once the temperature is higher than the set value, the program will trigger the corresponding output action. Through the output pin, the microcontroller or the processor can drive the warning light 15 to light up and emit a warning signal;
[0026] At this time, grasp the handle 12 to lift the valve plate 8. When the magnetic block 11 is magnetically attracted to the lower end of the baffle 10, the inside of the drainage cover 5 is opened. The fan 9 operates to generate a suction force. The suction force acts on the inside of the liquid crystal television through the drainage cover 5, accelerating the air flow inside the liquid crystal television and quickly taking away the heat inside the liquid crystal television. When natural heat dissipation cannot meet the heat dissipation requirements, the heat dissipation effect of the liquid crystal television is improved.
[0027] The above specific embodiments are only several preferred embodiments of the present utility model.
