Abstract
The utility model discloses a projection television device. For the projection television device, a heat source on a circuit main board is connected with a metal shell through a radiating fin; and two sides opposite to the metal shell and adjacent to the heat source are provided with radiating holes. As the area of the metal shell is relatively large and the heat source is directly contacted with the shell through the radiating fin, the radiating area can be increased and the heat conducting efficiency can be improved; simultaneously, air convection can be formed by the radiating holes at two sides of the metal shell, thus further improving the radiating efficiency. Compared with the prior art, the projection television device has high radiating efficiency and does not need fans for forcing radiation, thus on the one hand reducing the volume of the device and being convenient to be carried, and on the other hand reducing noise. Simultaneously, the whole machine has the advantages of small power consumption, lower cost and high assembly efficiency.
Description
Technical field
The utility model relates to the heat abstractor field, particularly relates to device for projection television.
Background technology
Along with the development of technology, can regulate screen size whenever and wherever possible and be subjected to more consumers and like.Because projection TV in the course of the work, mainly the heat that is produced by ray machine is bigger, must be in time the heat of its generation be shed, and not so can reduce the life-span of ray machine.Therefore existing device for projection television heat radiation is mainly dispelled the heat by fan, makes that the volume of projection TV is bigger on the one hand, is inconvenient to carry; When playing TV or other amusement functions, the noise that radiator fan produces is big on the other hand, can interference user to the appreciation of program, the power consumption of complete machine is bigger simultaneously, cost height, shortcoming such as efficiency of assembling is low.
The utility model content
The technical problem that the utility model mainly solves provides a kind of device for projection television that can quick heat radiating, and its radiating efficiency height reduces noise and volume.
In order to address the above problem, the utility model provides a kind of device for projection television, this device for projection television comprises: metal shell and cooperate fixing cap with this metal shell, be provided with the circuit main board of projection TV in this metal shell, thermal source on the described circuit main board is connected with metal shell by fin, is provided with louvre relatively and with the contiguous both sides of thermal source at described metal shell.
Preferably, the louvre position that is positioned on the metal shell of described cap is provided with the bar shaped louvre.
Preferably, described metal shell comprises allumen.
Preferably, described device for projection television also comprises control panel, and it is fixing that this control panel cooperates with metal shell, and is connected with circuit on the circuit main board.
The utility model device for projection television is connected by fin the thermal source on the circuit main board with metal shell, be provided with louvre relatively and with the contiguous both sides of thermal source at described metal shell.Because the area of described metal shell is bigger, and thermal source is directly contacted with housing by fin, can increases area of dissipation and improve heat conduction efficiency; The louvre of the both sides of metal shell can form cross-ventilation simultaneously, further improves radiating efficiency.Compared with prior art,, can reduce the volume of device on the one hand, be convenient for carrying, can reduce noise on the other hand because the radiating efficiency height does not need fan to carry out forced heat radiation.The power consumption of complete machine is bigger simultaneously, and cost is lower, shortcomings such as efficiency of assembling height.
Description of drawings
Fig. 1 is the utility model device for projection television example structure schematic diagram;
Fig. 2 is housing and circuit main board fit structure schematic diagram;
Fig. 3 is Fig. 1 STRUCTURE DECOMPOSITION schematic diagram.
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of device for projection television embodiment.
Described device for projection television comprises: metal shell 1 and cooperate fixing cap 2 with this metal shell 1, be provided with the circuit main board 5 of projection TV in this metal shell 1, thermal source 6 on the described circuit main board 5 is connected with metal shell 1 by fin 7, is provided with louvre 11 the relative of described metal shell 1 and with both sides that thermal source 6 is close to.
The utility model device for projection television is connected by fin 7 thermal source on the circuit main board 56 with metal shell 1, be provided with louvre 11 the relative of described metal shell 1 and with both sides that thermal source 6 is close to.Because the area of described metal shell 1 is bigger, thermal source 6 is directly contacted with metal shell 1 by fin 7, can increase area of dissipation and improve heat conduction efficiency; The louvre 11 of the both sides of metal shell 1 can form cross-ventilation simultaneously, further improves radiating efficiency.Compared with prior art,, can reduce the volume of device on the one hand, be convenient for carrying, can reduce noise on the other hand because the radiating efficiency height does not need fan to carry out forced heat radiation.The power consumption of complete machine is bigger simultaneously, and cost is lower, shortcomings such as efficiency of assembling height.
In the present embodiment, louvre 11 positions that described cap 3 is positioned on the metal shell 1 are provided with bar shaped louvre 31, can further promote the inner air and outer air convection current, improve the efficient brimful of tears of loosing.Described metal shell 1 can adopt allumen, because the light weight of this alloy is convenient for carrying.Described device for projection television also comprises control board, and it is fixing that this control panel 2 cooperates with metal shell 1, and is connected with circuit on the circuit main board 5.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
