The specific embodiment
Below with reference to accompanying drawing, the device specific embodiment of the present utility model and embodiment are described in detail.
Heat abstractor that can be bidirectional ventilated on a kind of LED casing of the present utility model, one of its specific embodiment as shown in Figure 5, is provided with a blower module 515 at LED casing 100 (accompanying drawing is not shown, same prior art), is used for heat radiation; On described casing 100, also be provided with a cavity 511, be used to assemble described blower module 515; Simultaneously, described blower module 515 is connected with described casing 100 by pivot structure, and the described blower module 515 that is used to overturn is to change the direction of ventilating.Compared with prior art, the utility model is rotationally connected the annexation of described blower module 515 with LED casing 100, and changes ventilation fan hole 111 into cavity 511 from fixedly connected changing into, is used for described blower module 515 upsets and ventilation.As seen, fan 214 fixedly connected in the prior art can only unidirectionally ventilate, or air intake, or air-out, and the blower module 515 that is rotationally connected in the utility model both can air intake can air-out, improved the radiating effect in the described casing 100 significantly.
Be preferably, as shown in Figure 5, described cavity 511 can be arranged on the chamber door 110, and described chamber door 110 can be hinged on described casing 100 by hinge 113, and can be provided with snap close 112 by described chamber door 110.
Further, as shown in Figure 6, described cavity 511 can be arranged on the first half of described chamber door 110, and for example described cavity 511 can be positioned at the left upper in described chamber door 110 outsides; The latter half at described chamber door 110 is provided with casing air vent 101.In the prior art, as shown in Figure 1, this casing air vent 101 is arranged on the described casing 100, the casing air vent 101 that the utility model will originally be processed on described casing 100 is changed into and is processed on the described chamber door, is not changing the manufacturing procedure that has reduced described casing 100 on the former basis that produces effect.
