[0002] The TV back panel refers to the back panel of the TV, which is usually made of plastic or hardware and is used to support and fix the internal components of the TV. There are many types of TV back panels, which mainly vary according to the size and brand of the TV. Common types of back panels on the market include hardware back panels, environmentally friendly back panels and plastic back panels, among which hardware back panels have high strength and good internal heat dissipation performance.

[0003] The current hardware TV back panel usually does not have a structure to actively dissipate heat from the TV's internal electronic components. In the high temperature environment of summer, if the TV is run for a long time, if the heat of the electronic components cannot be quickly discharged, it is prone to jamming, resulting in a reduced experience.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-size hardware TV back panel structure, including an exoskeleton and an external protruding backpack plate integrally installed in the exoskeleton, a heat conduction zone plate is arranged on the external protruding backpack plate, the area where the heat conduction zone plate is located is the heating position of the electronic components inside the TV, and the position and specific shape of the heat conduction zone plate can be adjusted and changed according to the actual situation during the actual design, a heat spreader and a thermal conductive paste that fit each other are arranged on the inner side of the heat conduction zone plate, and the side of the thermal conductive paste that faces away from the heat spreader is used to contact with the electronic components, and two heat pipes are horizontally installed on the external protruding backpack plate, and a plurality of external heat discharge plates distributed at equal intervals are welded on the ends of the two heat pipes that face away from the heat spreader, so as to facilitate The heat of the heat pipe is dispersed on several external heat dissipation plates, wherein the external heat dissipation plates are welded as a whole by a lower heat absorbing plate and an upper heat dissipation plate. Both the lower heat absorbing plate and the upper heat dissipation plate are tilted in design but at different angles. The existence of the upper heat dissipation plate produces an effect, that is, after the airflow below is blown to the lower heat absorbing plate, the flow rate of the airflow will be slowed down under the action of the upper heat dissipation plate, thereby prolonging the contact time between the airflow and the upper heat dissipation plate, so as to take away more heat. A positioning strip is fixedly welded on the outside of the external protruding backpack plate below the heat pipe, and several groups of equally spaced air intake chute and exhaust vertical slots are formed on the positioning strip. An oblique fan is installed in each air intake chute, and the oblique fan needs to be powered by the power supply of the TV.

[0006] As a preferred implementation scheme: the heat spreader is located between the thermal paste and the heat pipe, and the heat pipe and the heat spreader are welded integrally; the thermal paste is directly attached to the heat-generating electronic components in the TV, and its model can be Laird 90000 and other models, which is used to perform good thermal conductivity and conduct heat to the heat spreader.

[0007] As a preferred implementation scheme: two heat pipes are symmetrically distributed on the protruding backpack board, and the heat pipes are U-shaped; one end of the heat pipe is located on the inner side of the protruding backpack board, and the other end is located on the outer side of the protruding backpack board.

[0008] As a preferred embodiment: a heat pipe installation groove is formed on the lower heat absorbing plate and passes through both sides thereof; wherein the heat pipe installation groove is used for the heat pipe to pass through horizontally and be welded.

[0009] As a preferred implementation scheme: the air inlet chute and the exhaust vertical chute are connected, and the oblique fan is designed to be inclined; the inclination angle of the oblique fan is 45°~70°, which is used to generate an upward high-speed airflow to facilitate the removal of heat from the external heat dissipation fins. At the same time, the presence of the positioning strip cannot occupy a large lateral space, so as to reduce the overall volume.

[0010] As a preferred embodiment: the lower heat absorbing plate has a steep inner wall, and the upper heat dissipating plate has a gentle inner wall.

[0011] As a preferred embodiment: an angle is generated between the steep inner wall and the gentle inner wall, and the angle is a; the range of a is 160° to 175°.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model, through the design of thermal conductive pads, heat spreader and two heat pipes, conducts the heat released by the electronic components inside the TV to the outside when they are working, and designs multiple oblique fans to work outside to achieve active heat dissipation, so as to speed up the heat dissipation efficiency, so that the electronic components in the TV can also work stably in a high temperature environment, reduce the probability of freezing, and ensure the use experience of the TV;

In the present invention, when the heat pipe exports heat to the external heat dissipation plate, an angle is generated with the help of the lower heat absorption plate and the upper heat dissipation plate. The upper heat dissipation plate can slightly slow down the flow rate of the airflow (but will not affect the oblique fan blowing it through), prolonging the contact time between the airflow and the upper heat dissipation plate, so as to more thoroughly blow away the heat from the upper heat dissipation plate and achieve a faster heat dissipation effect.

[0025] Please refer to Figures 1 to 6 , an embodiment provided by the present utility model: a large-size hardware TV backplane structure, including an outer skeleton 1 and an outer protruding backplane 2 integrally installed inside the outer skeleton 1. A heat conduction area plate 201 is provided on the outer protruding backplane 2. The area where the heat conduction area plate 201 is located is the heat generation position of the internal electronic components of the TV. In actual design, the position and specific form of the heat conduction area plate 201 can be adjusted and changed according to actual conditions. A heat sink plate 202 and a heat conduction sticker 203 that are mutually attached are provided on the inner side of the heat conduction area plate 201. The side of the heat conduction sticker 203 facing away from the heat sink plate 202 is used to contact the electronic components. Two heat pipes 204 are horizontally installed on the outer protruding backplane 2. The heat sink plate 202 is located between the heat conduction sticker 203 and the heat pipes 204, and the heat pipes 204 are integrally welded to the heat sink plate 202. The heat conduction sticker 203 is directly attached to the heat-generating electronic components inside the TV. Its model can be selected from models such as Laird HD90000, etc., which is used to play a good heat conduction role and conduct heat to the heat sink plate 202. The two heat pipes 204 are symmetrically distributed on the outer protruding backplane 2, and the heat pipes 204 are designed in a U shape. One end of the heat pipe 204 is located inside the outer protruding backplane 2, and the other end is located outside the outer protruding backplane 2;

[0026] A plurality of equally spaced outer heat dissipation fins 205 are welded to one end of the two heat pipes 204 facing away from the heat sink plate 202, so as to disperse the heat of the heat pipes 204 on the plurality of outer heat dissipation fins 205. The outer heat dissipation fins 205 are integrally welded by a lower heat absorption plate 2051 and an upper heat dissipation plate 2052. A heat pipe installation groove 2053 penetrating both sides thereof is formed on the lower heat absorption plate 2051. The heat pipe installation groove 2053 is used for the heat pipe 204 to horizontally pass through and be welded. Both the lower heat absorption plate 2051 and the upper heat dissipation plate 2052 are inclined but have different angles. The presence of the upper heat dissipation plate 2052 has an effect that after the airflow below blows onto the lower heat absorption plate 2051, the flow rate of the airflow will be slowed down under the action of the upper heat dissipation plate 2052, so as to extend the contact time of the airflow with the upper heat dissipation plate 2052 and facilitate taking away more heat;

[0027] On the outer side of the protruding backpack plate 2 and below the heat pipe 204, a positioning strip 206 is fixedly welded. A number of groups of intake inclined slots 2061 and exhaust vertical slots 2062 distributed at equal intervals are formed on the positioning strip 206. An inclined fan 2063 is installed in each intake inclined slot 2061. The inclined fan 2063 needs the power supply of the TV (or other types of external power supplies) for power supply. The intake inclined slot 2061 and the exhaust vertical slot 2062 are communicated, and the inclined fan 2063 is inclined. The inclination angle of the inclined fan 2063 is 45° - 70°. It is used to generate a high-speed airflow obliquely upward to facilitate taking away the heat of the outer heat sink 205. At the same time, the presence of the positioning strip 206 does not occupy a large lateral space to facilitate reducing the overall volume. The lower heat absorption plate 2051 has a steep inner wall 2054, and the upper heat dissipation plate 2052 has a gentle inner wall 2055. An included angle is generated between the steep inner wall 2054 and the gentle inner wall 2055. This included angle is a, and the range of a is 160° - 175°.

[0028] Working principle: In the work of the present utility model, during installation, according to the design positions of the electronic components in different models of TVs, the heat conduction area plate 201, the heat dissipation plate 202 and the heat conduction sticker 203 are designed to the specified positions. Among them, the heat conduction area plate 201 protrudes a part towards the inner side of the protruding backpack plate 2 to facilitate the better installation of the heat dissipation plate 202 and the heat conduction sticker 203, and makes the heat conduction sticker 203 contact the electronic components. Because the heat conduction sticker 203 is made of a soft material, it can be pressed on the surface of the electronic components to a certain extent. During work, the heat released by the electronic components is directly conducted to the heat dissipation plate 202 through the heat conduction sticker 203, and then quickly transferred to the outer side of the protruding backpack plate 2 through the two heat pipes 204, that is, transferred to the two groups of outer heat sinks 205. At the same time, make a number of inclined fans 2063 run synchronously and blow directly at the two groups of outer heat sinks 205 to quickly blow out the heat, and then fast and effective heat dissipation can be realized to ensure the stable operation of the TV in a high-temperature environment.
