Description

Technical Field

[0001] This utility model relates to a heat sink for television sets, specifically a novel combined high-efficiency heat sink. Background Technology

[0002] Televisions are an essential appliance in people's homes. The most important internal structure of a television is the circuit board. When the circuit board is working, it releases heat, so a heat sink is needed to dissipate the heat.

[0003] The heat sinks used in the circuit boards of current TVs are usually made of aluminum or copper and fixed to the main control chip on the circuit board. Therefore, they can only provide passive heat dissipation. If the ambient temperature is high and the main control chip is working under high load, it is easy to reduce the frequency because the heat cannot be dissipated, which will affect the operation of the TV. Utility Model Content

[0004] The purpose of this invention is to provide a novel combined high-efficiency heat sink. By using heat pipes to quickly transfer the heat from the main control chip on the circuit board to multiple heat sinks, and with the operation of a turbine fan to actively blow the heat off the heat sinks, the heat dissipation efficiency can be greatly improved and the phenomenon of frequency reduction can be avoided.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel combined high-efficiency heat sink, including a heat dissipation mechanism disposed on a TV back panel. The TV back panel includes a plate body, which is a cavity structure with an opening at the bottom and a hollow interior. Multiple support columns are fixed on the inner side of the plate body. The heat dissipation mechanism includes a top seat and a base disposed on one side of the top seat. The base is used to contact the main control chip of the circuit board inside the TV and conduct heat. In this embodiment, the base is made of copper. Multiple heat pipes are disposed between the top seat and the base. The heat pipes are evenly spaced, and multiple heat sinks are disposed at the ends of the heat pipes away from the top seat. A turbine fan is disposed on one side of the multiple heat sinks. The exhaust port of the turbine fan faces the multiple heat sinks, and the turbine fan is disposed on an outer heat-conducting plate. The outer heat-conducting plate has a U-shaped design and is fixed to the outside of the top seat.

[0006] Preferably, an air inlet is provided on the top of the board and an air outlet is provided on the side of the board. A first dustproof net is installed on the board at the air inlet and a second dustproof net is installed on the board at the air outlet. The first dustproof net corresponds to the air inlet position of the turbine fan, and the second dustproof net corresponds to the position where hot air is blown out, so as to facilitate the heat dissipation from the inside of the board to the external environment and complete the heat dissipation of the circuit board inside the TV.

[0007] Preferably, the heat pipe includes a bent section and a heat-conducting section and a heat-dissipating section respectively disposed at both ends of the bent section. The heat-conducting section is fixed between the top seat and the base, and the heat-dissipating section is fixed to multiple heat sinks.

[0008] Preferably, the multiple heat dissipation parts are all horizontally arranged, and the heat dissipation parts are distributed at both ends of the top base.

[0009] Preferably, multiple screws are installed on the lower end face of the outer heat-conducting plate, and the multiple screws are driven into multiple support columns respectively.

[0010] Preferably, the turbine fan and multiple heat sinks are fixed to the mounting plate, and a connecting plate is provided between the mounting plate and the external heat conduction plate. The two ends of the connecting plate are fixed to the mounting plate and the external heat conduction plate, respectively.

[0011] Preferably, multiple heat-conducting pads are provided on the lower end face of the outer heat-conducting plate, and both the outer heat-conducting plate and the base are horizontally arranged.

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

[0013] This invention incorporates a heat dissipation mechanism. Multiple heat pipes within this mechanism directly contact the main control chip (the component that generates the most heat) on the circuit board inside the television. Since the heat pipes have a much higher thermal conductivity than aluminum or copper sheets, they can quickly dissipate heat and transfer it all to a heat sink on one side. Combined with a turbine fan, the heat is directly exhausted along the air outlet on the back panel of the television, achieving active heat dissipation. This significantly reduces the temperature of the main control chip, allowing it to maintain stable operation for extended periods and preventing frequency throttling. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] Please see Figure 1 One embodiment of this utility model is a novel combined high-efficiency heat sink, which includes a TV back panel 1. The TV back panel 1 includes a plate body 11. An air inlet is provided on the top of the plate body 11, and an air outlet is provided on the side of the plate body 11. A first dustproof net 12 is installed on the plate body 11 at the air inlet, and a second dustproof net 13 is installed on the plate body 11 at the air outlet.

[0024] Please see Figure 2The TV back panel 1 has a heat dissipation mechanism 2 on its inner side. The panel 11 is a cavity structure with an opening at the bottom and a hollow interior. Multiple support columns 14 are fixed on the inner side of the panel 11.

[0025] Please see Figure 3 The heat dissipation mechanism 2 includes a top seat 21 and a base 22 disposed on one side of the top seat 21. The base 22 is used to contact the main control chip of the circuit board inside the TV and conduct heat. In actual assembly, a layer of thermal paste (i.e., thermal grease) can be applied between the base 22 and the main control chip. In this embodiment, the type is copper. Multiple heat pipes 23 are disposed between the top seat 21 and the base 22, so the heat absorbed by the base 22 can be transferred to the heat pipes 23. The multiple heat pipes 23 are evenly distributed, and multiple heat sinks 24 are disposed at the ends of the multiple heat pipes 23 away from the top seat 21. A turbine fan 25 is disposed on one side of the multiple heat sinks 24. The first dust filter 12 corresponds to the air inlet position of the turbine fan 25, and the second dust filter 13 corresponds to the position where the turbine fan 25 blows out hot air, so as to facilitate the exhaust of heat from the inside of the board 11 to the external environment, thus completing the heat dissipation of the circuit board inside the TV. The exhaust port of the turbine fan 25 is directly facing the multiple heat sinks 24. The heat from the heat sink 24 and multiple heat pipes 23 is ultimately released onto the heat sink 24. Then, with the help of the turbine fan 25, cool air is drawn in from the air inlet and the heat on the heat sink 24 is blown out from the air outlet, thus completing active cooling. The turbine fan 25 is set on the external heat conduction plate 27, which has a U-shaped design and is fixed to the outside of the top base 21. Multiple thermal pads 271 are set on the lower end face of the external heat conduction plate 27. The external heat conduction plate 27 and the base 22 are both set horizontally. The thermal pads 271 contact the components with low heat generation on the circuit board inside the TV and dissipate heat from them. The thermal pads 271 are of the Laird HD90000 model. Multiple screws 28 are installed on the lower end face of the external heat conduction plate 27. The screws 28 are driven into multiple support columns 14, so that the TV back panel 1 and the heat dissipation mechanism 2 can be fixed as one unit, and the heat dissipation mechanism 2 is fixed to the inside of the TV back panel 1.

[0026] Please see Figure 4 The heat pipe 23 includes a bent portion 232 and a heat-conducting portion 231 and a heat-dissipating portion 233 respectively disposed at both ends of the bent portion 232. The heat-conducting portion 231 is fixed between the top seat 21 and the base 22. The heat-dissipating portion 233 is fixed to multiple heat sinks 24. The heat-dissipating portion 233 and the heat sinks 24 can be fixed by reflow soldering or through-fin process. The multiple heat-dissipating portions 233 are all horizontally arranged and distributed at both ends of the top seat 21, so that the structure of the heat-dissipating portion 233 is nearly symmetrical at both ends of the top seat 21, thus maintaining the balance and structural stability of the heat pipe 23.

[0027] Please see Figure 5The turbine fan 25 and multiple heat sinks 24 are fixed on the mounting plate 26. A connecting plate 29 is provided between the mounting plate 26 and the external heat conduction plate 27. Both ends of the connecting plate 29 are fixed to the mounting plate 26 and the external heat conduction plate 27 respectively, so that the mounting plate 26 can support the turbine fan 25 and the heat sinks 24.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
