Wherein, each fan housing inside has in order to prevent that rainwater from infiltrating the louver in the fan housing.
Wherein, the bottom of each fan housing has a screen pack.
Wherein, being used for the storehouse plate that the air intake body installs is the wallboard with door-plate, and is used for storehouse plate that the air draft body installs for having the wallboard that is oppositely arranged before and after the wallboard of door-plate with this.
Wherein, this supply fan and scavenger fan are respectively a cross flow fan by DC power supply.
Wherein, in this air draft body, has the mutual separated dividing plate of number.
The utility model beneficial effect:
Heat extraction structure according to the utility model formation, under the normal power supply situation, its valve can seal the air port of intake and exhaust, the air-conditioning of communication cabinet inside can not leaked, and when extraneous power breakdown, and can keep the rack internal temperature in the operating temperature range of setting, moreover, the electric power of drive fan can be reached by standby direct current, need not increase extra gen-set, in addition, the screen pack that is provided with on the fan housing can effectively completely cut off mosquito, in foreign matter and the dust entry communication rack, so the utlity model has the value utilized on the industry and the enhancement of effect.
According to design spirit of the present utility model is to do multiple variation or modification, and for example the position of air inlet and exhaust outlet can change according to need.
About other purposes of the present utility model, advantage and feature, can graphicly understand by the detailed description of following preferred embodiment and with reference to appended.The utility model can be implemented with multiple different form.It now will only be example but non-in order to the embodiment of restriction and with reference to appended graphic as follows with regard to the utility model preferred construction description of contents.
