Description

M291162 IV. Creation Description (1) [New type of this type of digital TV] [Previous technology in the TV set is analogous to the signal in the signal. I, however, is analogous, and then gradually, it is gradually received by its TV. Because the number, the reception can be achieved, and the use condition is used to satisfy the consumption direction, the design of the digital TV is developed, and the purpose of the same can be set, for example, - reading the digital phase

The technical field relates to a heat dissipation structure of a digital television, especially the heat dissipation formed by the internal component configuration and structure ^

The development process progresses the main process of receiving the good signal. Because of its sound penetration, the signal is better than the quality. The signal is excellent, and the demand function is also in line with this trend. In addition to watching movies and other actions

T. In the past, most of the 'the degree of goodness of the TV set' depends on the lack of TV penetration and constant quality. Therefore, the number of TVs in the digital TV is also superior to the analog audio quality, such as the car in recent years. The e-commerce company has become a miniaturized and powerful, small-sized and miniaturized development, making the digital TV necessary components, and minimizing the same digital TV, and multimedia functions. The performance quality of the display is significantly related to the location of the receiving antenna. It is replaced by the technical number of the terrain or building video transmission signal, which will improve the mainstream of the TV. Interest, so even if it is used on the ground or in hand, it is like the development trend of household products. Gradually, multi-functionality is a product that is easy to carry, and therefore, in the thin and light, the appearance of thin and beautiful makes it easy to use the inside of the body. 'Combined with multi-function - both listening and listening Μ P 3 music, M291162 is placed in the large-scale view of the visual design of the spectroscopy, and the appearance of the fan is not considered to be normal. From this structure, 酉 合 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Convenience and thinness fans provide the main components of the outer shell to dissipate heat. The air has the most relevant zero body function. The heat also provides the key to heat dissipation. Because of the design, the relative heat dissipation components are still installed and the aging time is considered. (2) In order to maintain the equivalent of the need to play the strong, digital power affects the digital components in the thinning component and holds its zero A fan, it is necessary to ring its miniaturized micro-heating digital TV in the [new content, therefore the main thermal structure of the needle creation, by the gap formed in the body standing heat dissipation channel area and efficiency plus cost [implementation method first please In the shape of the thin body casing, and the action of the multi-media, the emission of the effective part of the normal operation of its internal space to make it heat-dissipating and considering whether the installation space also has a cost increase affects its power supply. The design is suitable for a kind of space between the components and the square fins on the heat dissipation area. The heat dissipation component is better for the maintenance of the components. Good, if you want to maintain the time, such as heat dissipation space, and shadow, even if you install a large reduction and a small picture, you can see that the long side presents a substantial semi-circle generated heat loss, the portable digital TV dispersion and components and housing The natural hot air inlet and the exhaust hole are parallel to the gas flow circuit, increasing its heat dissipation, and in a limited space and without increasing the fruit. The housing of the authoring embodiment is in the shape of 'the housing can be divided into

The partition 1 is provided with a partition 11 and the front shell 1 In the two device areas, the display 11 and the control panel (not shown) are installed in the t-zone, and a control circuit area is provided in the t-zone of the partition 11. The control circuit area is provided with a tuner. 12 and a card reading device 13, a fixing base is arranged above the card reading device 13, and an antenna 14 is connected, and is locked by a bolt member 141. A recessed space 2 1 is defined on the right side of the rear case for placing the battery and covering the outside of the battery as a detachable battery shell surface 22, which is fastened to the rear shell 2 by a buckle 2 3; After the circuit area, the shell surface of the shell 2 has a plurality of venting holes 24 corresponding to the position of the receiver 13 , and a bracket 25 is disposed on the left side of the venting hole 24 for supporting the entire housing standing angle, in the bracket 2S In the lower part, a plurality of heat dissipation air inlet holes 26 are opened near the bottom semicircular end of the rear case 2, and an elongated accommodation space 27 is opened at the semicircular end of the top case of the rear case 2 for accommodating the antenna 14' Bottom round hole 28 '

It is convenient for the connection end of the antenna 14 to pass through, and in the ^ - & + # I hot vent hole 29, the top case half of the rear case 2 is opened on the side of the two-space 27, the number / Μ, the hole 30 is opened at least Another hole is opened on both sides of the jj3 end. Please refer to the second figure, the heat dissipation vent hole (not shown). The inner surface of the rear case 2 will not be controlled by electricity. When the housing of the present invention is assembled, a gap is formed between the recessed space of the battery and the recessed space of the battery, and the heat generated when the circuit area is controlled is generated. The gap, therefore, when the electric rise is controlled, the air inside the rear shell 2 is heated to the space where the surrounding air is heated, and the inner space is started to flow through the rear shell, and the core 29 is produced by the structural elements. The heat dissipation vents in the top of the heat-dissipation hole in the top 30, the ventilating vents, and the escaping, let the surrounding cold air M291162 θ, creation instructions (4) ' ' ' ' ^ After the heat dissipation at the bottom of the Ϊ 2 The air inlet hole 26 enters the casing and flows through the gap of the f to replenish the hot air flowing upward, so that the air becomes a flowing state, which causes a convection effect, and the gap generated by the structural element becomes a substantial heat dissipation passage. Referring to the second figure in May, in the heating element disposed in the control circuit area, in the present embodiment, a tuner 13 is mounted, and a heat sink 3 substantially equivalent to the area of the frequency modulator 13 is mounted, and the heat dissipation is performed. The fins 3 and the inner surface of the rear case 2 have a gap, and the hot fins 3 extend along a long heat sink 3丨, and a gap is formed adjacent to the heat dissipation vent hole 24 formed on the rear case 2, and the gap is matched. Referring to the fourth _ when the circuit area is operated, the heat generated by the air is removed from the casing through the natural heat venting holes 28, and the heat fins 3 mounted on the heating element will be The heat is absorbed and accelerated by the convection of the air, and the heat is further transmitted to the extended long fins 31, and the heat dissipating area is enlarged, and then convected by the air and directly discharged from the immediately adjacent venting holes 24' To enhance the efficiency of its overall heat dissipation structure. Referring to the fifth figure in May, when the user uses the compact digital television of the present invention, the whole housing is supported by the bracket 25, and the housing is inclined at an angle and is not shielded from the bottom end of the rear housing 2. The long-shaped dilated piece 3 is opened, so that cold air can smoothly enter the casing through the heat-dissipating air inlet 26, and the natural convection effect is performed, and the antenna is erected when the digital television of the present invention is used. The state is such that the hot air is smoothly discharged from the monthly heat vent hole 29 opened in the antenna accommodating space, and the vent hole 24 which is opened above the elongated heat sink 31 enhances the heat dissipation efficiency and drives the surrounding air to form. The convection is close to '' to make the overall heat dissipation more complete. &"
