Abstract
The utility model provides an outdoor surface-mount full-color LED display screen which is used for lowering the temperature of a display screen, so that the display screen can work more stably, and the service life of the screen can be prolonged. The outdoor surface-mount full-color LED display screen comprises an LED module and a control circuit module that are connected with each other, wherein a corrugated pipe temperature lowering device is arranged in a clearance between the LED module and the control circuit module; and the corrugated pipe temperature lowering device is connected with a liquid pump. A corrugated pipe is made of metal. The outdoor surface-mount full-color LED display screen is applicable to an outdoor screen and is also applicable to an indoor screen.
Description
Technical field
The utility model relates to LED display, particularly relates to a kind of outdoor surface welded LED display.
Background technology
Be distributed with more intensive LED lamp on each box unit of Surface Mount LED display, as Chinese patent application number is record in the 200620015689.6 open applications, be distributed with more intensive LED lamp on the LED module, because the LED light fixture has the big characteristics of thermal value, therefore as can be known, its structure does not well solve heat dissipation problem by this structure.
For the outdoor large LED display, because led chip is more powerful, its heat dissipation problem is more outstanding.Present outdoor surface welded full-color LED display screen does not also have good cooling profiles, and this will directly influence the serviceable life of display screen.
Summary of the invention
The utility model provides a kind of outdoor surface welded full-color LED display screen, is used for to the display screen cooling, so that the serviceable life of its more stable work and prolongation screen.
In order to achieve the above object, the utility model proposes a kind of outdoor surface welded full-color LED display screen, comprise LED module and control circuit module, the LED module links together by connector and control circuit module; In the space between described LED module and described control circuit module the corrugated tube heat sink is installed, this corrugated tube heat sink is connected with the liquid pump.Corrugated tube is a metal material.
Preferably: the pipe corner of described corrugated tube is provided with the insulating heat-conductive sheet.
Preferably: at the side of display screen the air cooling equipment of corrugated tube has been installed, corrugated tube is stretched out by the side of display screen, is provided with the forced-ventilated fan assembly above corrugated tube.
Preferably: described LED display is divided into left half screen and right half screen, and inner corrugated tube is divided into left half screen bellows system and right half screen bellows system by left half screen and right half screen, and two bellows system are the marker space with the screen axis; Two sides are equipped with the air cooling equipment of corrugated tube about display screen, the bellows system of left half screen and right half screen respectively by about two air cooling equipment wind cooling temperature lowerings.
Preferably: described LED display is divided into left half screen and right half screen, and inner corrugated tube is divided into left half screen bellows system and right half screen bellows system by left half screen and right half screen, and two bellows system are the marker space with the screen axis; In the space between marker space, LED module and control circuit module fan is installed.
Preferably: described side at display screen has been installed the air cooling equipment of corrugated tube, and corrugated tube is stretched out by the side of display screen, is provided with the forced-ventilated fan assembly at the side of corrugated tube.
Beneficial effect is as follows:
Compared to existing technology, the utility model utilizes the big gap between Surface Mount LED module and the control circuit module, increased the corrugated tube heating radiator therein, the heat that this heating radiator can in time send the LED lamp is derived outside the screen, carry out heat interchange by shielding outer auxiliary radiating device again, to reach purpose to the display screen cooling.For outdoor high-power LED display screen, cooling-down effect of the present utility model is particularly evident, therefore, can improve the stability of outdoor surface welded LED display and prolong its serviceable life.

Embodiment
The utility model provides a kind of outdoor surface welded full-color LED display screen, and it comprises LED module and control circuit module, and the LED module links together by connector and control circuit module.In the space between LED module and control circuit module the corrugated tube heat sink is installed, this corrugated tube heat sink is connected with the liquid pump.
Embodiment is referring to Fig. 1 and shown in Figure 3.
Referring to Fig. 3, outdoor full color Surface Mount LED display 5 is made up of the splicing of four screen unit boxs.Referring to Fig. 1, each screen unit box comprises LED module 1 and control circuit module 2.LED module 1 and control circuit module 2 link together by connector.Between LED module 1 and control circuit module 2, there is gap 10.Because the quantity of the LED lamp that distributes on the LED module 1 is very many, it is equivalent to the LED quantity that distributes on the casing of non-Surface Mount LED display, so the space in this gap 10 is relatively very big, and corrugated tube 3 is installed in this gap 10, and corrugated tube 3 is connected with the liquid pump.Corrugated tube is a metal material.Liquid coolant is a water.
Referring to shown in Figure 2, the pipe corner of corrugated tube 3 is bonded with insulating heat-conductive sheet 4.This insulating heat-conductive sheet 4 both can in time be delivered to the heat on its contact devices on the corrugated tube, can prevent the leak electricity short-circuit problem that corrugated tube causes once in a while again.
Referring to Fig. 3, this display screen is divided into left half screen and right half screen.The corrugated tube of display screen inside is divided into left half screen bellows system and right half screen bellows system by left half screen and right half screen, and two bellows system are the marker space with the screen axis.In the space between marker space, LED module and control circuit module axis fan 9 is installed.
At the dual-side of Surface Mount LED display 5 air cooling equipment of corrugated tube has been installed all, corrugated tube is stretched out by the dual-side of display screen, is provided with the top fan 7 of forced-ventilated above corrugated tube 3.Side at corrugated tube 3 is equipped with side fan 8.
