Abstract
The utility model discloses an LED display screen radiator which comprises an LED screen body, a semiconductor refrigerator, a fan and an LED lamp array. A cavity is formed by the LED screen body and a casing. The semiconductor refrigerator and an aluminum substrate are arranged in the cavity. One side of the aluminum substrate is connected with the LED lamp array, and the other side is connected with an LED circuit board. One side of the semiconductor refrigerator is connected with a cold conducting piece which is connected with the fan, and the other side is connected with radiating fins. The fan directly faces the LED circuit board. According to the utility model, the LED display screen radiator has the advantages of good radiating effect and high efficiency; the service lives of an LED lamp and the related products are effectively prolonged; social resources are greatly saved; waste is reduced; and the market value is strong.
Description
Technical field
The utility model relates to heat dissipation technology field, is specifically related to a kind of LED display heat abstractor.
Background technology
As everyone knows, LED is light-emitting diode namely, is a kind of solid-state semiconductor device, and it can directly be converted into luminous energy by electricity.So because that LED luminous element has in concrete use is energy-conservation, long service life, inside do not have the harmful substances such as mercury be convenient to the feature that reclaims now LED be widely used people's productive life suffered.
Along with the development of LED technology, the LED display that is light source making with LED is now also by the extensive use of people institute, LED display is a kind of by controlling the display mode of semiconductor light-emitting-diode, it is generally comprised of a lot of light-emitting diodes, relies on the light on and off of LED light source lamp to show character in specific works.In concrete enforcement, it can be used for the display screen of the various information such as display text, figure, image, animation, market, video, video signal.LED display not only can also be used for outdoor environment for indoor environment, has advantages of that projecting apparatus, video wall, LCDs are incomparable.Why in widespread attention LED display is and developed rapidly, is that the advantage that has with itself is inseparable.These advantages sum up and are: brightness is high, operating voltage is low, power consumption is little, miniaturization, life-span are long etc.
So due to LED display in specific works, be form by converting electrical energy into luminous energy carry out work in its work and in extraneous transmission of video signal, inevitably can produce some heats, general LED display all needs to work at ambient temperature, too high working temperature not only can shorten its useful life, the situation that more likely there will be the inner electric elements of LED display screen to be burnt, generation for fear of this situation has all been installed some radiator structures with regard to the LED display screen occurring at present, but existing radiating effect and radiating efficiency or not fully up to expectations.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide the LED display heat abstractor that a kind of good heat dissipation effect and efficiency are high.
The technical solution adopted in the utility model is such:
A kind of LED display heat abstractor, comprise LED screen body, semiconductor cooler, fan and LED lamp array, described LED screen body and shell form a cavity, in described cavity, be provided with semiconductor cooler and aluminium base, the one side of described aluminium base is connected with LED lamp array, and another side is connected with LED circuit plate; Described semiconductor cooler one side is connected with cool guide sheet, and cool guide sheet is connected with fan, and another side is connected with radiating fin; Described fan faces LED circuit plate.
As preferably, in the cooling piece left and right sides of described semiconductor cooler, coat heat-conducting silicone grease.
As preferably, described LED circuit plate surrounding is coated with sealing heat-conducting glue.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model good heat dissipation effect and efficiency are high, and efficiently and effectively has extended the useful life of LED lamp and Related product thereof, thereby has greatly saved social resources, has reduced waste, has very strong market value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1-LED shields body, 2-LED circuit board, 3-aluminium base, 4-LED lamp array, 5-radiating fin, 6-fan, 7-semiconductor cooler, 8-cool guide sheet.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of LED display heat abstractor, comprise LED screen body, semiconductor cooler, fan and LED lamp array, described LED screen body and shell form a cavity, in described cavity, be provided with semiconductor cooler and aluminium base, the one side of described aluminium base is connected with LED lamp array, and another side is connected with LED circuit plate; Described semiconductor cooler one side is connected with cool guide sheet, and cool guide sheet is connected with fan, and another side is connected with radiating fin; Described fan faces LED circuit plate.
Heat-conducting silicone grease is coated in the cooling piece left and right sides at described semiconductor cooler; Described LED circuit plate surrounding is coated with sealing heat-conducting glue.
The utility model is coated heat-conducting silicone grease at the cooling piece left and right sides of semiconductor cooler, then contacts respectively cool guide sheet and radiating fin.The cold air that cool guide sheet produces semiconductor distributes fast, by fan, cold air is sent to LED circuit plate surface, and in refrigeration, semiconductor cooler is also discharging a large amount of heats.To reject heat in air by radiating fin and LED screen body, thereby realize the cooling in screen body.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
