Description
Technical field
The utility model relates to LED display field, is specifically related to the LED display of excellent heat radiation performance, and it is for substituting existing larger LED ad display screen.
Background technology
LED has replaced a lot of traditional lighting light fixtures gradually with its power savings advantages; Existing LED advertisement electronic curtain is universal coming, because the service time of advertisement electrical screen is long, adopts LED can more embody energy saving as light source; For larger LED advertisement screen, its bandwagon effect is very good, energy-saving effect is more obvious simultaneously, but what be accompanied by is that the heat of generation of LED illuminating module is more and more, and be difficult for being discharged from, the light efficiency variation that causes LED illuminating module affects serviceable life of LED illuminating module simultaneously; Traditional radiator structure has active heat removal and passive heat radiation, commonly fan cooling and heat radiator heat radiation, and its radiating effect is all not ideal for large-size screen monitors or super large screen LED display.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of LED display with cooling mechanism, and it has more outstanding heat-sinking capability.
The utility model solves the technical scheme that its technical matters adopts: a kind of LED display with cooling mechanism, comprise housing, and each face of housing is all offered housing air vent, and housing is that light transmissive material is made towards the panel of LED illuminating module; In described housing, wiring board is installed, on wiring board, uniform installation LED illuminating module, offers wiring board air vent on described wiring board, and wiring board back side direction is provided with refrigeration treadmill body;
Described refrigeration treadmill body comprises heat exchange flat board, the pipeline of uniform installation evaporator in heat exchange flat board, and the interior also uniform air vent that offers of heat exchange flat board, the pipeline of offering position and evaporator of air vent staggers;
Described refrigeration treadmill body rear is provided with radiator fan;
Above-mentioned evaporator is serially connected in refrigeration mechanism, and described refrigeration mechanism is air-conditioning system, the concrete air compressor machine being connected in series successively by refrigerant tubing that comprises, and condenser, throttling valve, evaporator, gas-liquid separator, refrigerant tubing finally takes back air compressor machine and forms circulation.
As a kind of preferred implementation of above-mentioned ventilation hole structure, described wiring board air vent and the housing housing air vent through hole center line on the panel of LED illuminating module overlaps.
As the preferred structure of disposed at air vent on above-mentioned housing, described housing upper and lower side is provided with fly net.
A kind of LED display with cooling mechanism described in the utility model, it has the following advantages:
The utility model is with the LED display of cooling mechanism, and it adopts the mode of ventilation and heat and refrigeration radiating to improve the heat-sinking capability of whole display screen, is highly suitable for the heat radiation of the LED display of large-size screen monitors or super large screen; Concrete, ventilation and heat adopts the structure of air vent, and housing has air vent, wiring board has air vent, and the flat board that simultaneously freezes also has air vent, and this mode has certain natural heat dissipation ability, also there is the advantage of Homogeneouslly-radiating simultaneously, be unlikely to produce the situation of screen somewhere temperature inequality; More specifically, the air-conditioning refrigeration system that refrigeration radiating adopts, the cooling power of last evaporator is all dispersed to heat exchange flat board uniformly, makes so whole heat radiation process adopt cold wind evenly to trim a LED display, and heat radiation homogeneity and cooling-down effect are very good.
