Description
Technical field
The utility model relates to cooling system, relates in particular to a kind of LED display cooling heat radiation system.
Background technology
LED display can show numeral, literal, graph image, not only can be used for indoor environment, and is widely used in outdoor environment, has projecting apparatus, video wall, the incomparable advantage of LCDs.Why LED is subjected to extensively paying attention to and is developed rapidly, is that the advantage that had with itself is inseparable.These advantages are summarized: the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and stable performance.The development prospect of LED is very wide, and at present just towards high brightness more, more high weather resistance, higher luminous density, higher uniformity of luminance, reliability, panchromaticization direction develop.
LED belongs to semi-conductor electronic device, and relatively more fragile, to environmental requirement, particularly temperature requirement is than higher, and environment temperature is high more, and aging speed is just fast more.LED display, particularly outdoor display screen are generally made the casing of sealing fully, and in the hope of reaching good waterproof effect, heat radiation brings very big obstacle but this is to display screen.The mode of existing display screen has two kinds, and the one, natural heat dissipation utilizes natural convection air that display screen is dispelled the heat.This mode generally is used for a little bigger distance, or caloric value such as indoor scan screen is little, and it is not very high display screen that heat radiation requires, and shortcoming is little for a distance, and the outdoor display screen of static scanning can't use.The 2nd, the display screen that can not satisfy the cooling requirement at natural heat dissipation carries out forced heat radiation, the forced heat radiation mode is divided into two kinds again, first kind is to accelerate cold loosing with fan, this mode has a large amount of gases to enter casing from the external world, the dust that gas carries, steam, static and smog have very big corrosion and damage to LED display; Second kind is to use air-conditioning equipment, and the air that has cooled off is in a large number sent in the casing, takes this to take away more heat, reduces the temperature of display screen, and this mode cost is higher, difficult in maintenance.
For LED display provides good heat radiating system more, reduce the temperature of LED display, make LED display more stable, prolong device lifetime.

The specific embodiment
As shown in Figure 1, the utility model comprises: be arranged on the LED display casing outside radiator 1, be arranged in the LED display casing and be close to the display screen back side heat dump 2, connect the circulating pump 3 of described heat dump inlet tube 5 and radiator outlet pipe 6, an and fluid box 4, described heat dump outlet 5 is connected with this fluid box 4 with radiator inlet tube 6, cooling liquid (can be water or some other good fluidity, the liquid that thermal capacity is bigger) circulates in above-mentioned closed system.The liquid circulation power is provided by circulating pump 4, and liquid is flowed in liquid conduits.Liquid conduits comprises the heat dump coiled pipe that abuts in the LED display back portion and the finned tube in the radiator, and connecting pipe.When flowing through heat dump 2, liquid absorbs the heat of LED display; When flowing through radiator, heat is dispersed in the air, reduces the LED display temperature inside by pipeline and fin.
Fig. 2 is the structural representation of radiator 1, comprises casing 13 and conduit 12, and cooling liquid imports the heat dump from radiator by circulating pump 3.
Preferably, radiator can also connect fin 11 according to the needs of heat radiation on its conduit.
In addition, when cooling fluid makes water, can also be provided with a rainwater receiver 7 in the radiator outside, this rainwater receiver is communicated with fluid box 4.So just can have to hand over utilizes rainwater to serve as cooling fluid.In order to guarantee that rainwater enters proper flow after the circulatory system, be provided with screen pack at the top of rainwater receiver, the duct entry 10 that is connected with described fluid box and rainwater receiver bottom prevent from impurity is brought in the fluid box from a distance.
Fig. 3 is the structural representation of heat dump 2, in this embodiment, uses snake pipe as heat exchanger, this snake pipe is close to the fixedly metal structure back side of display screen, by abundant conduction, inner heat is taken to the outside, and heat is loose in atmospheric environment by radiator.Be understandable that the pipeline of described heat dump 2 can be arranged in other shape according to the size and the space of display screen, as rectangle, waveform, is not used in restriction the utility model.
