When the operating power is below a certain percentage of full load, the main exhaust fan is not started, and the normal use of the rectifier cabinet can be realized by utilizing the self-heat dissipation of the unpowered hood.
Description
Technical Field
The utility model relates to a power field indicates especially one kind and fills energy-saving high-power rectifier cabinet in electric pile user's outer container room formula.
Background
The split charger generally consists of a centralized rectifier cabinet and an operating terminal, and is widely used due to the advantages of high applicable power and self-expansion of the number of terminals. However, the rectifier cabinet has a large power and a large amount of heat, so that a large amount of heavy electric fans are required to be arranged to dissipate heat from the cabinet body. And because the rectifier cabinet is not always in a full-load operation state, when the rectifier cabinet is normally operated at a low power, the exhaust fans are not all started, but the number of the started fans is gradually increased according to the power of use, so that the working mode is easy to cause the situation that one adjacent fan is started and the other adjacent fan is stopped, and the situation that the fan blades are reversed can occur due to the action of air flow of the fan which is not started at the moment, and the hot air which is just exhausted is pumped into the rectifier cabinet again, thereby greatly reducing the overall heat dissipation efficiency.
In order to solve the problems that the noise is high, the cost is high, and the power loss is high when the split charging pile is not fully loaded, and the defects of the high-power centralized rectification adopted by the split charging pile in the prior art, a new design is carried out by an inventor.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model discloses main aim at provides an fill energy-saving high-power rectifier cabinet of electric pile user's outer container room formula to can realize centralized rectifier cabinet low noise, reduce power loss when reaching cost reduction and low-power operation, and increase the purpose of heat-sinking capability effect.
In order to achieve the purpose, the utility model provides an fill energy-saving high-power rectifier cabinet in electric pile user's outer box room formula, it mainly comprises outdoor formula box room, several rectifier cabinet, array cooling fan and the unpowered hood of several, the rectifier cabinet set up side by side in outdoor formula box room rear portion, cooling fan locates outdoor formula box room back wall, and the unpowered hood is located and should be said outdoor formula box room top. So that the air exhaust efficiency is high by means of the unpowered hood, and the air exhaust device can be operated lightly to effectively operate under the condition that the breeze is not less than 0.2 meter or the indoor and outdoor temperature difference exceeds 0.5 ℃. The load of the electric exhaust fan is further reduced, and a part of the electric exhaust fan can be replaced, so that the cost is greatly reduced, and the noise is reduced. When the operating power is below a certain percentage of full load, the main exhaust fan is not started, and the normal use of the rectifier cabinet can be realized by utilizing the self-heat dissipation of the unpowered hood.
Furthermore, the heat radiation fan and the unpowered hood correspond to the plurality of rectifier cabinets respectively and correspondingly, and the unpowered hood can be arranged at one side, close to the heat radiation fan, of the top end of the outdoor box house, so that the efficiency is further improved.
Among them, it is preferable that: the outdoor box room front wall is provided with an air inlet, and the air inlet is provided with a filtering device. And the top end of the outdoor box house can form a downward slope from the middle part to the front wall and the rear wall of the outdoor box house. Further make unpowered hood axis and the slope become 90 degrees angles.
The beneficial effects of the utility model reside in that, with the help of above-mentioned technical scheme, utilize the design of unpowered hood, can make inside air produce effectual convection current during the fan is out of service, utilize the hot convection current of air that outside natural wind-force and indoor outer temperature difference caused, promote the turbine rotation to usable centrifugal force and negative pressure effect are with indoor hot-air outgoing. Therefore, the centralized rectifier cabinet is low in noise, the cost is reduced, the power loss is reduced when the rectifier cabinet operates at low power, the heat dissipation capability is improved, and the outstanding advantages are achieved.

Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. And the following examples are only for illustrating the present invention, but not for limiting the scope of the present invention.
As shown in fig. 1-7, the utility model discloses an outdoor box house type high-power rectifier cabinet. The equipment mainly comprises an outdoor box house 11, a plurality of rectifier cabinets 12, a plurality of groups of cooling fans 13 and a plurality of unpowered hoods 14.
In the embodiment of the present invention, the turbine is driven to rotate by the structure of the unpowered hood installed on the top of the apparatus (the top of the outdoor box house 11) and by the thermal convection of air caused by the external natural wind and the temperature difference between the indoor and the outdoor, so that the hot air generated by the rectifier cabinet 12 can be exhausted by the centrifugal force and the negative pressure effect. Because the unpowered hood 14 has high air exhaust efficiency, the unpowered hood can be operated lightly to operate effectively under the condition that the breeze is not less than 0.2 meter or the indoor and outdoor temperature difference exceeds 0.5 ℃. The utility model discloses to unpowered hood 14's use, reduced the load of electric exhaust fan, and the partly electric exhaust fan of fungible (cooling fan 13), therefore greatly reduced the cost, subtracted the noise. Through test, when the operating power is below a certain percentage of full load, the main exhaust fan can not be started, and the normal use of the rectifier cabinet can be realized by completely utilizing the self-heat dissipation of the unpowered hood, so that the energy consumption is greatly reduced.
Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can be modified or replaced with other embodiments without departing from the spirit and scope of the present invention, and all such modifications and equivalent substitutions are intended to be encompassed by the scope of the following claims.
