Detailed description of the invention

It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.

As shown in Figures 1 to 4, the heat abstractor of the present embodiment comprises: lid 10 and air exhausting device 20. Lid 10 and LEDThe casing 70 of display unit connects, and the installing space of the interior formation power supply module 40 of lid 10, is provided with exhaust outlet on lid 10.Air exhausting device 20 is arranged on lid 10 and is positioned at exhaust outlet place, and air exhausting device 20 drains into interior lid 10 gas outside lid 10.

The technical scheme of application the present embodiment, lid 10 is connected with the casing 70 of LED display unit, and power supply module 40 is arranged onIn installing space in lid 10, power supply module 40 comprises power supply and other electric elements. Power supply and other electric elements produceHeat force to discharge lids 10 by the air exhausting device 20 arranging on lid 10, by air exhausting device 20 by power supply and other electricityThe heat of device element is discharged fast, and cold air is constantly inhaled into, and has reduced like this temperature of lid 10 inside. The present embodimentTechnical scheme reduced the design to power supply module 40, the requirement of selecting, reduced the cost of power supply module 40, reducedDue to the overheated fault causing of the electric elements such as power supply.

As shown in Figures 4 to 7, in the technical scheme of the present embodiment, heat abstractor also comprises: be arranged on exhaust outlet outsideOver cap 30. Over cap 30 is connected with lid 10, forms and be communicated with the inside and outside air channel of lid 10 between over cap 30 and lid 10.Over cap 30 not only has protective effect to lid 10, and over cap 30 forms air channel with lid 10. Air exhausting device will coverThe heat of body 10 inside drains into air channel, then by air channel, heat is discharged in air. The technical scheme over cap 30 of the present embodimentCoordinate tightly with lid 10, over cap 30 is consistent with the height of fin, above-mentioned over cap 30 and lid 10 one integrated mass,Both outward appearance collocation are reasonable, coordination, succinct, attractive in appearance; Utilize the gap between fin to do aeration structure, avoided designing againSpecial air duct and affect product appearance. Particularly, air exhausting device is fan, and said structure is made simple, saves cost. Air draftDevice is in discharging hot-air, and air is sucked by air exhausting device from the outside of lid 10, and hot-air is discharged from cold air like thisBe inhaled into, the temperature of lid 10 inside reduces, and the heat that power supply module 40 work produce is discharged in time, power work like thisTime occur fault rate can reduce widely.

In the technical scheme of the present embodiment, over cap 30 is tightly connected with lid 10. Said structure be conducive to over cap 30 withLid 10 forms waterproof construction, is specially while raining, and over cap 30 forms waterproof to lid 10, and can not affect ventilation and heat.Particularly, in the technical scheme of the present embodiment, exhaust outlet is positioned on the roof of lid 10, and over cap 30 comprises and lid 10Roof connect top board and the side plate being connected with the sidewall of lid 10. The over cap 30 of said structure has been protected air draft on the one handDevice, on the other hand, over cap 30 forms waterproof construction with lid 10. Preferably, the classification of waterproof of the present embodiment can reachIP55, such heat abstractor can be applicable to outdoor occasion well.
