Abstract
The utility model discloses a novel cooling system for a box type LED display screen. The cooling system comprises a box type LED display screen body and a radiating system in a box; an independent chamber which does not exchange air with other space is formed in the box of the LED display screen; a power supply and at least one power supply cooling system fan are arranged in the independent chamber; and the independent chamber is also provided with an independent power supply cooling system air outlet and an independent power supply cooling system air inlet which are communicated with the external directly. The design ensures that cold air can directly enter the power supply from the external without being heated by other electron devices, and simultaneously heat produced by the power supply is directly discharged out of the box, so that the using temperature of the box is guaranteed and the consistency of the temperature in the box is improved.
Description
Technical field
The utility model relates to a kind of design of Cooling System of electronic equipment, especially relates to a kind of cooling system of box-type LED display.
Background technology
The box-type display screen comprises that mechanical casing, some LED show module, power-supply system, cooling system and control system etc.All components and parts all are fixed on the mechanical casing.In working order, each casing displays image information separately.
The heat of box-type LED display is mainly derived from LED lamp, power supply and other electronic original part.Power supply and LED lamp are main thermals source.The efficient of power supply is 70%, means that 30% electric energy has become heat.The efficient of LED lamp is about 10%, and also 90% electric energy is transformed into heat energy in other words.Operate as normal and long useful life for guaranteeing electronic equipment, all these heats need be dispersed into the casing outside by cooling system.
The maximum operation (service) temperature of reference power supply the chances are 65 ℃, the maximum operation (service) temperature of other electronic original parts is the link of a weakness with power supply greater than 100 ℃ especially.
Box-type LED display generally now, electronic component all is fixed on mechanical box house, and whole box body has only a cooling system, and the heat that whole system produces all is dispersed into the casing outside by this cooling system.The shortcoming of this general casing cooling system is:
1, for casing, ambient temperature is exactly the air intake vent temperature of casing.The maximum permissible service temperature of power supply is exactly the air intake vent temperature of power supply own.Cold air enters casing from the air intake vent of casing, by other original paper heating of box house, enters the air intake vent of power supply then, and the hot blast of power supply eliminating simultaneously also can enter the air intake vent of power supply by backflow.In this case, the temperature of power supply air intake vent is higher than casing (air intake vent) temperature, because power supply is the weak link of whole system, so just cause the highest environment serviceability temperature of the permission of whole box body to reduce.
2, the heat of power supply is more concentrated, and this has just caused the inhomogeneous of whole box body interior temperature distribution.Near the power supply temperature is higher than other positions, thereby has influenced the consistency of LED lamp brightness.
Summary of the invention
The purpose of this utility model provides a kind of box-type LED display novel cooling system, and it can overcome the deficiencies in the prior art, and a kind of cooling system of new model is provided for the box-type LED display.
For achieving the above object, the utility model is taked following design:
A kind of box-type LED display novel cooling system, comprise the cooling system in box-type LED display body and the casing, in the casing of LED display, set up one not have the independent room of air exchange with other spaces, power supply is placed in independent room inside, and a power supply cooling system fan is installed at least, and offer the independent current source cooling system air outlet and the independent current source cooling system air intake vent of direct and exterior in independent room.
Described independent room is positioned at the half side back half interval of casing one of LED display; Cooling system in the casing has two air intake vents, is divided into the below of casing both sides, and air outlet is positioned at the top of casing one side.
The utility model box-type LED display novel cooling system has two line cooling systems, wherein, power supply has independently power supply cooling system air outlet, power supply cooling system air intake vent and power supply cooling system fan separately, the heat that power supply produces directly directly is discharged to the casing outside by this cooling system, and heat that other original paper produces in the casing and power supply produce heat not influence each other, so good heat dissipation effect.
The utility model has the advantages that:
1, cold air directly enters power supply from the external world, and without the heating of other electronic devices, power supply produces heat and directly is discharged to the casing outside simultaneously, thereby has guaranteed the serviceability temperature of casing.
2, the heat of power supply generation directly is excluded casing, to other not influence of components and parts, has improved the consistency of box house temperature.

Fig. 1 is the utility model box-type LED display novel cooling system stereoscopic-state structural representation (forward sight, a LED lamp plate before removing).
Fig. 2 is the utility model box-type LED display novel cooling system structural representation (backsight is removed the LED lamp plate).
Fig. 3 be among Fig. 2 A-A to cutaway view.
Below in conjunction with drawings and the specific embodiments the utility model is described in further details:
Embodiment
Consult Fig. 1, Fig. 2 and shown in Figure 3, the utility model box-type LED display novel cooling system is based on the improvement on the former cooling system, comprise the cooling system in box-type LED display body and the casing, the cooling system in this casing is the cooling system (being similar general casing cooling system in prior art) that is made of casing fan 1, casing cooling system air intake vent 2 and casing cooling system air outlet 5.
The improvement of the utility model box-type LED display novel cooling system is: set up one not have the independent room 100 of air exchange with other spaces in the casing of LED display, power supply 6 is placed in this independent room inside, and a power supply cooling system fan 7 is installed in independent room at least, offer at least one independent current source cooling system air outlet 3 and at least one independent current source cooling system air intake vent 4 of direct and exterior.
Design has formed two discrete cooling systems in the utility model box-type LED display thus.In the present embodiment, described independent room 100 is arranged in the casing of LED display a half side back half interval.The cooling system of its casing comprises an air outlet 5, two air intake vents 2 and fans 1, and two air intake vents of casing cooling system are divided into the below of both sides.Cold air enters box house simultaneously from two air intake vents 2 of casing.Under the driving of casing fan 1, hot-air is discharged to the casing outside from casing air outlet 5, thereby heat is discharged to the casing outside in casing.Power supply cooling system comprises a power supply cooling system air outlet 3, a power supply cooling system air intake vent 4 and a power supply cooling system fan 7, cold air enters the power supply installing space from power supply cooling system air intake vent 4, hot-air is discharged to the casing outside by power supply cooling system air outlet 3 under the driving of fan 7, be discharged to the casing outside thereby power supply is produced heat.Like this, the heat that makes power supply produce directly is excluded casing, and to other not influence of components and parts, two of casing air intake vents 2 form the cooling air duct that spreads all in the casing with air outlet 5 in addition, so improved the consistency of box house temperature.
The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection range that the utility model is applied for a patent.
