The utility model content
The technical problems to be solved in the utility model is, at the defective of the above-mentioned top air-out heat exchange type rack of prior art, provides a kind of that the fan airstream direction changes, heat exchange efficiency height, rack top air-out heat exchange air channel that water resistance is good avoided.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of rack top air-out heat exchange air channel, comprise the wind channel that is located at the rack equipment compartment outside, and be arranged on the wind chamber that rack equipment compartment top is connected with wind channel; Described wind channel and wind chamber connection are useful on the installed surface that fan is installed, described installed surface is positioned at described wind chamber rear portion, the other end with respect to described installed surface in the described wind channel has and the extraneous air inlet that is connected, and the other end with respect to described installed surface in the described wind chamber has and the extraneous air outlet that is connected; The airflow direction that described fan work blows out is parallel to the rack end face over against air outlet.
In a kind of rack top air-out heat exchange of the present utility model air channel, be provided with the ventilation water bar in the described wind chamber, described wind chamber is separated into anti-pool and heat transfer zone by described ventilation water bar.
In a kind of rack top air-out heat exchange of the present utility model air channel, the bottom in the anti-pool of described wind chamber is connected with the rhone of rack doorframe both sides.
In a kind of rack top air-out heat exchange of the present utility model air channel, the base plate of described wind chamber heat transfer zone can be made by the heat conduction good material.
In a kind of rack top air-out heat exchange of the present utility model air channel, the base plate front and/or the reverse side of described wind chamber heat transfer zone is provided with " U " type heat conduction tooth.
Implement rack top air-out heat exchange of the present utility model air channel, have following beneficial effect: the airflow direction that fan work of the present utility model blows out is over against air outlet, be parallel to the rack end face, thereby guaranteed air-flow has enough range abilities and avoided airflow direction in wind chamber change, made that air-out is smooth and easy, improved the heat exchange efficiency of rack.In addition, be provided with the ventilation water fender in the wind chamber, it is divided into anti-pool and heat transfer zone with wind chamber, the bottom in anti-pool is connected with the rhone of rack doorframe both sides, when using out of doors, after outside rainwater might be splashed into the anti-pool of wind chamber by the air outlet of below, rack top cover forward position, because the ventilation water bar is arranged in the wind chamber, rainwater can not enter into the heat transfer zone of wind chamber, more can not enter into the equipment compartment of rack, but discharge by the rhone that the doorframe both sides are connected, make whole rack have favorable waterproof property; The base plate of top wind chamber heat transfer zone is made by the heat conduction good material, helps the interior heat of equipment compartment and conducts rapidly, and the wind that utilizes fan to blow out is then taken away heat rapidly in the wind chamber heat transfer zone, thereby increases heat exchange power; In order to increase heat exchange area, can be provided with " U " type heat conduction tooth with the base plate front and/or the reverse side of the adjacent wind chamber heat transfer zone of rack equipment compartment, make heat exchange more abundant, further improved heat exchange efficiency.
