The efficiently heat-dissipating LED display screen case comprises shells of the cases, heat-dissipating outlets on the cases, fans arranged at the heat-dissipating outlets and corrugated tube coolers, each corrugated tube cooler comprises a corrugated tube and a heat-absorbing tube, the corrugated tubes are arranged at the heat-dissipating outlets and outside the fans, the heat-absorbing tubes are arranged on the inner walls of the sides of the shells, and the corrugated tubes are connected in series with the heat-absorbing tubes. Compared with the prior art, the heat-dissipating effect of the case can be more enhanced, the service life of the LED display screen can be prolonged, the fault rate of the display screen can be reduced, or the occurrence time of dead pixels on the LED display screen can be delayed.
Description
Technical field
The utility model relates to a kind of LED display.
Background technology
The casing of existing LED display is provided with special thermovent, and radiator fan is installed on thermovent, and this thermovent is provided with netted fan protection plate.This fender can be used for preventing that exotic such as people's hand or other foreign matter from touching fan, also has the effect of certain dust protection.
Because the power of LED display is increasing now, its application is more and more wider, and applied environment also becomes increasingly complex.Heat dissipation problem in the casing of display screen seems and particularly protrudes.Bad heat radiation can reduce life-span of LED, increases bad point of LED on the display screen.
The utility model content
The utility model technical matters to be solved is: a kind of LED display casing of high efficiency and heat radiation is provided, is used to improve the heat radiation in the casing, improve its radiating effect, increase the stability and the life-span that prolongs display screen of display screen.
In order to solve above-mentioned technical matters; The utility model proposes a kind of LED display casing of high efficiency and heat radiation; Comprise shell, the thermovent on the casing of casing and the fan that is located at the thermovent place; And this casing also comprises the corrugated tube cooling device, and the corrugated tube cooling device comprises corrugated tube and the endothermic tube that is used to dispel the heat; Corrugated tube is arranged on the outside of said thermovent place, said fan, and endothermic tube is arranged on the inwall of shell sidepiece, and corrugated tube and endothermic tube are serially connected.
Preferably: mobile liquid coolant is arranged in the said corrugated tube, and liquid coolant is water or oil.
Preferably: be provided with the supporter that is used to support corrugated tube weight in the corner of said corrugated tube, supporter protrude said casing the surface its be fixed on the casing.
Preferably: the pipeline between two adjacent casings is communicated with through connecting pipe serial connection.
Preferably: said endothermic tube is a corrugated tube.
Preferably: said endothermic tube comprises a fin of being responsible for and being located on the person in charge.
The beneficial effect of the utility model: compare prior art; The utility model has increased the corrugated tube heat abstractor and on cabinet wall, has been provided with endothermic tube at the thermovent place of casing; And inside the pipeline of this device, fill the liquid coolant that flows, in this structure, endothermic tube can absorb the heat of box house; Through the corrugated tube of liquid with heat transferred place, air port under the fan, by fan to corrugated tube is dispelled the heat.This structure has made full use of the function of the radiator fan on the casing; This radiator fan can be discharged the hot-air in the casing on the one hand; On the other hand can be further with the heat on the cabinet wall; Derive back row through endothermic tube and corrugated tube and shed, so its relative prior art can improve the radiating effect of casing greatly.This seems very necessary for the LED display that is in hot environment, and it can prolong the serviceable life and the rate of breakdown that reduces display screen of LED display, or postpones the time of origin of bad point on the LED display.In addition, corrugated tube can also play the protection and the dustproof effect of fan.

Embodiment
The utility model proposes the LED display casing; It comprises shell, the thermovent on the casing of casing and the fan that is located at the thermovent place; And this casing also comprises the corrugated tube cooling device, and the corrugated tube cooling device comprises corrugated tube and the endothermic tube that is used to dispel the heat; Corrugated tube is arranged on the outside of thermovent place, fan, and endothermic tube is arranged on the inwall of shell sidepiece, and corrugated tube and endothermic tube are serially connected.
An example structure of the utility model is as depicted in figs. 1 and 2.Be the structure of two adjacent casings shown in Fig. 1, first casing 1 and second casing 2 connect together.
The back side of the shell 8 of casing is provided with thermovent 7, and 7 places are provided with radiator fan 3 at thermovent.
This casing also comprises the corrugated tube cooling device, and the corrugated tube cooling device comprises corrugated tube 4 and the endothermic tube 11 that is used to dispel the heat.Corrugated tube 4 is arranged on the outside of thermovent 7 places, fan 3, is fixed on the back outer wall 81 of shell, and endothermic tube 11 is arranged on the inwall 80 of shell sidepiece, and corrugated tube 4 is serially connected with endothermic tube 11.
Endothermic tube can be corrugated tube shown in Figure 2, also can be that endothermic tube 12 shown in Figure 3 is made up of with the fin 121 that is located on the person in charge 120 person in charge 120.Mobile liquid coolant is arranged in the corrugated tube 4, and liquid coolant is water or oil.Be provided with the supporter 5 that is used to support corrugated tube weight in the corner of corrugated tube 4, it is fixed on the surface of supporter 5 protrusion casings on the casing.First the adjacent casing 1 and the pipeline of second casing 2 are communicated with through rubber-like flexible pipe connecting pipe 6 serial connections.
