Description
Technical field
The utility model relates to a kind of radiator structure of inverter rack.
Background technology
Inverter is the Core equipment of photovoltaic, wind power grid-connected generating, play by direct current change into can be grid-connected alternating current.In the process of progressively dwindling at rack volume, the integral heat sink of rack is a challenge for the space layout of its each device of inside, and reasonably radiator structure design can effectively utilize enclosure interior, dwindles the volume of rack.Existing most of cooling machine cabinet is all that the distribution section of high power device and switch, filtering device is carried out separately to independently heat dissipation design, make like this cost of design high, space availability ratio is lower, cause inverter volume large, use cooling fan number many, the reliability of equipment is impacted.
Utility model content
The utility model provides a kind of radiator structure of new inverter rack, to solve the defects such as the cost of traditional scheme design is high, and space availability ratio is lower.
Basic solution of the present utility model is as follows:
A radiator structure for inverter rack, its special character is: at interior of equipment cabinet, have a vertical baffle interior of equipment cabinet is divided into front chamber and rear chamber, the top of this vertical baffle has through hole; Described front chamber is mainly used in placing filter unit, switching device and power distribution unit, and rear chamber is mainly used in placing reactor; The bottom of front chamber communicates with the bottom of rear chamber, and the position that the air inlet of rack communicates corresponding to this is arranged at side lower part before rack; The top of rear chamber is provided with centrifugal blower, and down, the air outlet of rack is arranged at upper lateral part after rack corresponding to the air outlet of centrifugal blower to the air inlet of centrifugal blower.
Based on above-mentioned basic solution, the utility model also can be done following optimization and limit and improve:
Two horizontally disposed toroidal membranes are installed in rear chamber, lay respectively at the both sides up and down of reactor, on toroidal membrane, be provided with a plurality of through holes; Wherein the toroidal membrane of downside higher than front chamber the position that communicates with rear chamber.
Air inlet and the air outlet of rack are provided with Air Filter.
The utlity model has following advantage:
(1) the utility model is divided into forward and backward chamber by dividing plate by rack, and switch, filtering device and distribution section are installed by front chamber, and reactor is installed by rear chamber, and space availability ratio is high, dwindles the volume of rack; Each device installation and maintenance are convenient and swift.
(2) interior of equipment cabinet only arranges a blower fan, is positioned at the top of rear chamber, and the device of forward and backward chamber all has cold air to flow through, and meets the requirement that each device of forward and backward chamber dispels the heat simultaneously, without separately designing air channel, increases blower fan.
(3) rear chamber is provided with the deep bead of twice annular, and the cross section in air channel is dwindled, and has increased the wind speed on the reactor surface of flowing through, and can take away more heat the unit interval, strengthens radiating effect.

Embodiment
The present embodiment is a kind of heat dissipation wind channel structure design of solar photovoltaic inverter rack, main feature is that interior of equipment cabinet is divided into front chamber and rear chamber by a vertical baffle by interior of equipment cabinet, its front chamber communicates in rack bottom with rear chamber, and relative with the air inlet of rack, the perforate of several places is arranged at the top of described vertical baffle.Wherein the front chamber of rack is mainly used in placing filter, switching device and power distribution unit, the rear chamber of rack is mainly used in placing reactor, the top of rack rear chamber is provided with backward centrifugal blower, the air outlet of blower fan is corresponding with the air outlet of rack, surrounding at reactor in the rear chamber of rack is provided with two toroidal membranes, is mainly used in reactor to dispel the heat.The radiator structure of this rack is simple, make full use of air channel dispels the heat fully to heater members, has improved the reliability of each device.
Fig. 1 is the front view of rack in the utility model embodiment, wherein the air inlet of rack is positioned at the below of cabinet front, corresponding with the position that rack bottom front chamber communicates with rear chamber, extraneous wind enters from air inlet, then by the air channel, bottom of rack, enter respectively front chamber and the rear chamber of rack, the device in each chamber is dispelled the heat.
Fig. 2 is the rearview of rack in the utility model embodiment, and wherein the air outlet of rack is positioned at the top of rear of cabinet, corresponding with the air outlet of rear chamber blower fan that install at top.
Fig. 3 is the structure chart of interior of equipment cabinet in the utility model embodiment, as shown in the figure, vertical baffle is divided into front chamber and rear chamber by interior of equipment cabinet, front chamber is near the front of rack, rear chamber is near the back side of rack, and front chamber is used for placing filter, switching device and power distribution unit, and rear chamber is used for placing reactor, wherein on the top of front chamber, according to the heating situation of device, on dividing plate, have several places ventilation hole, be conducive to the heat radiation of heater members and the outflow of front chamber's heat.Described rear chamber is provided with reactor, in upper and lower two positions of reactor, two toroidal membranes is installed, and is mainly used in increasing wind speed, accelerates the radiating rate on reactor surface.The top of described rear chamber is provided with backward centrifugal blower, for by the hot-air of interior of equipment cabinet from bottom to top, by blower fan, is discharged to rack outside, and the air outlet of blower fan and the air outlet of rack are corresponding simultaneously.
Fig. 4 is the flow graph in the interior air channel of rack in the utility model embodiment.As shown in the figure, natural wind enters interior of equipment cabinet from the air inlet of rack, then the front chamber and the rear chamber that flow into respectively rack dispel the heat to the heater members in each chamber, the principle making progress away according to hot-air, thermal current in front chamber can gather the top of front chamber, has hole, a few place, on the dividing plate due to front chamber top under the effect of rear chamber's top blower fan, thermal current in the front chamber rapidly tapping from dividing plate flows to rear chamber, finally by blower fan, discharges rack.The natural wind that flows into rear chamber under the effect of rear chamber's top blower fan updraft along reactor to upper reaches, because reactor has two toroidal membranes around, natural wind is all gathered around reactor, because total blast volume is constant, the sectional area that wind passes through diminishes, so the wind speed through reactor surface has been strengthened, and has accelerated like this radiating rate on reactor surface, has guaranteed the steady operation of reactor.
