It is to describe the purpose of specific embodiment, it is not intended that in limitation the utility model.
Please refer to Fig.1 to Fig. 5, divulge information Lumbar 100 the present embodiment provides one kind, including housing 10 and enclosed by the housing 10
Into cavity volume, 10 two sides of housing offer left and right air inlet hole 3 respectively, and the 10 upper and lower bottom surface of housing offers respectively
Upper and lower exhaust vent 4；Multiple ventilation driving devices are equipped with the cavity volume, the multiple ventilation driving device is set to drive respectively
Air is set to enter from the left and right air inlet hole 3 in the housing and be flowed out from upper and lower exhaust vent 4.
In the present embodiment, the multiple ventilation driving device includes multiple turbofan, and the turbofan includes first
20 and second turbofan 21 of turbofan, first turbofan 20 are set to drive air to enter shell from left air inlet hole 3
In vivo, and respectively flowed out from upper and lower exhaust vent 4；Second turbofan 21 is set to drive air to enter housing from right air inlet hole 3
It is interior, and flowed out respectively from upper and lower exhaust vent 4.It should be noted that the gas flow of common aerofoil fan is parallel with shaft,
And the gas flow of turbofan can be in the space hold of smaller perpendicular to shaft, relatively traditional radiator fan, turbofan
The air quantity of lower output bigger, improving radiating effect.
Further, the turbofan includes wind inlet of fan 5 and fan outlet 6, it is necessary to which explanation is the wind
It is corresponding with the exhaust vent 4 that 10 upper and lower sides of housing are set to be fanned out to air port 6.
In the present embodiment, the setting quantity of the turbofan is 4, first turbofan 20 and second whirlpool
It is respectively 2 to take turns fan 21, it is to be understood that in other embodiments, the setting quantity of the turbofan can be more than
