Abstract
The invention relates to a surface-mounted indoor single/double-color unit plate, which comprises a frame and a circuit board fixedly arranged inside the frame, wherein a surface-mounted single-color or double-color light emitting diode of a lattice structure is welded on one surface of the circuit board; the diode is connected to the control board by virtue of a connector, and a gap is reserved between the diode and the control board; a radiating pipe is arranged inside the gap; the radiating pipe is in a zigzag structural form; the upper part of the radiating pipe clings to the diode by virtue of an insulating and heat conduction sheet; and the lower part of the radiating pipe clings to the control board by virtue of an insulating and heat conduction sheet. The surface-mounted indoor single/double-color unit plate disclosed by the invention is simple in structure and excellent in heat radiating performance.
Description
Technical field
The present invention relates to the indoor single double-colored cell board of a kind of surface-mount type, belong to LED display technical field.
Background technology
LED full-color display screen, the lattice display module be made up of multiple LED light emitting diode or display unit, it has, and brightness is high, operating voltage is low, power consumption is little, the life-span is long, shock-resistant and steady performance.Along with the continuous progress of science and technology, and LED display technique is constantly perfect, and LED full-color display screen, as a kind of important means of Information Communication, has become one of mark of urban information modernization construction.
At present, owing to adopting the display unit of surface-mount type full-color light-emitting diode to have the features such as production efficiency is higher, cost is low, easy to maintenance, surfacing is beautiful than the display unit of the full-color light-emitting diode of traditional employing human weld mode, and be widely used in LED full-color display screen.But each box unit of surface mounted LED display screen is distributed with more intensive LED light emitting diode, and the thermal value of its LED light emitting diode is larger, for consisting of large LED full color display, its heat dissipation problem is more outstanding.If heat can not distribute well, not only can affect the stability of LED display display, also can shorten the serviceable life of LED light emitting diode and other electronic components.The existing radiating mode to large LED full color display has and adopts air-conditioning heat dissipation or add fan and dispel the heat, but, either heat dissipation electrical is costly too high, or radiating effect is not good, and heat dissipation problem cannot be solved well.
The patent No. is 2012203844200 provide a kind of Surface Mount full-color LED display screen for this reason, its version is: the mode adopting corrugated tube heat radiation, its heat dispersion is improved, but also there is certain defect in this kind of version, be in particular in that the contact area between corrugated tube and diode, control panel is little, therefore cause its heat dispersion not satisfactory, Given this need to be improved further.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide that a kind of structure is simple, the indoor single double-colored cell board of the surface-mount type of excellent radiation performance.
The technical solution used in the present invention is for this reason: the present invention includes framework (1) and be fixed on the wiring board (2) in framework (1), the Surface Mount monochrome of the one side welding lattice structure of described wiring board (2) or dichromatic LED (3), by connector (4) connection control plate (5), between described diode (3) and control panel (5), there is gap in described diode (3);
Radiating tube (6) is provided with in described gap, described radiating tube (6) is Zigzag type version, radiating tube (6) top is close on diode (3) by insulating heat-conductive sheet (7), and radiating tube (6) bottom is close on control panel (5) by insulating heat-conductive sheet (7).
Described radiating tube (6) top, bottom are provided with medium entrance (61), and described radiating tube (6) middle part is provided with media outlet (62).
Some radiating fins (63) are provided with in described radiating tube (6).
The both sides in described gap are provided with fan.
Advantage of the present invention is: 1) the present invention arranges Zigzag type radiating tube, described radiating tube top, bottom respectively with diode, control panel close contact, so greatly increase contact area, its heat dispersion is greatly improved, and has good heat dispersion;
2) medium entrance is arranged on radiating tube top and the bottom by the present invention, and media outlet is arranged in the middle part of radiating tube, this assures the heat sink contacted with diode, control panel and be heat eliminating medium, the heat that such diode, control panel give out all can obtain effectively distributing in time, and heat dispersion is effectively guaranteed;
3) some radiating fins are provided with in radiating tube of the present invention, the heat one that such diode, control panel give out is by carrying out heat interchange with its radiating tube directly contacted, two carry out reinforcement heat radiation by radiating fin, and take out of outside gap eventually through the medium flowed in the middle part of radiating tube, further increase radiating effect;
4) the present invention is provided with fan in both sides, gap, and the heat existed in the heat of radiating tube and gap distributes by such fan arrange timely, further increases heat dispersion.
In sum, structure of the present invention is simple, but heat dispersion is but effectively guaranteed, and has good actual effect through using.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 be framework, 2 be wiring board in figure, 3 be diode, 4 be connector, 5 be control panel, 6 be radiating tube, 7 for insulating heat-conductive sheet;
61 be medium entrance, 62 be media outlet, 63 for radiating fin.
Embodiment
The present invention includes framework 1 and be fixed on the wiring board 2 in framework 1, the Surface Mount monochrome of the one side welding lattice structure of described wiring board 2 or dichromatic LED 3, by connector 4 connection control plate 5, between described diode 3 and control panel 5, there is gap in described diode 3;
Be provided with radiating tube 6 in described gap, described radiating tube 6 is Zigzag type version, and radiating tube 6 top is close on diode 3 by insulating heat-conductive sheet 7, and radiating tube 6 bottom is close on control panel 5 by insulating heat-conductive sheet 7.
Described radiating tube 6 top, bottom are provided with medium entrance 61, are provided with media outlet 62 in the middle part of described radiating tube 6.
Some radiating fins 63 are provided with in described radiating tube 6.
The both sides in described gap are provided with fan.
The course of work of the present invention is: heat eliminating medium of the present invention enters radiating tube 6 from the medium entrance 61 of top and the bottom, through the flowing in radiating tube 6, flow out eventually through media outlet 62, fan can be devoted oneself to work simultaneously in addition, timely heat is distributed, the existence of radiating fin 63 makes the heat of top and the bottom radiating tube 6 can conduct heat timely on the radiating tube 6 at middle part in addition, and therefore heat dispersion is improved further.
