It is an object of the invention to solve by the following technical programs:
This DC charging heat dissipating method, including internal recycle radiating mode and outer circulation radiating mode; Wherein internal recycle radiating mode is, makes air-flow be circulated the process of cooling inside DC charging device; Wherein outer circulation radiating mode is, is discharged by the air-flow within DC charging device, and the air-flow outside simultaneously flows into this device.
Further, the feature of the present invention also resides in,
Wherein when the internal temperature of DC charging device is lower than the temperature of the external temperature of DC charging device or setting, use internal recycle radiating mode
Wherein when the internal temperature of DC charging device is higher than the temperature of the external temperature of DC charging device or setting, while opening internal recycle heat radiation, open outer circulation radiating mode.
Another technical scheme of the present invention is, a kind of DC charging device using above-mentioned heat dissipating method, including being arranged on the internal recycle heat dissipation channel and outer circulation heat dissipation channel closed in rack; Inner cycle channel includes the power model, the cooling fan that set gradually according to gas flow direction, internal recycle air channel and heat exchanger; Outer circulation heat dissipation channel includes absorbing the air intake blower fan of ambient atmos and outwardly discharging the heat exchanger of gas.
Further, the feature of the present invention also resides in,
Heat exchanger is wherein provided with the internal recycle air inlet being connected with internal recycle air channel, the bottom of heat exchanger is provided with internal recycle air outlet.
Wherein rack has external circulation air inlet arranging air intake blower fan place, and rack has outer circulation air outlet at heat exchanger place.
Wherein external circulation air inlet can be opened or close.
Wherein outer circulation air outlet has at least 2.
Wherein cooling fan is arranged on the top of rack, and power model is in the lower section of cooling fan, and internal recycle air channel is arranged on the centre of cooling fan and heat exchanger.
Wherein air intake blower fan is arranged on the middle part of heat exchanger, and heat exchanger is arranged on top or the sidepiece of rack.
A kind of DC charging device of the present invention and heat dissipating method thereof provide the benefit that: the rack of closing can effectively stop dust to enter and power model is produced impact; When ambient temperature is lower than design temperature, adopts heat exchanger radiating mode namely to use internal recycle heat dissipation channel completely, avoid during heat radiation directly exchanging with extraneous air, can effectively prevent dust from entering in cabinet; When ambient temperature is higher than design temperature, it is necessary to start internal recycle heat dissipation channel and outer circulation heat dissipation channel simultaneously.
Further, the closeable external circulation air inlet having on rack, when being used alone internal recycle heat dissipation channel, close external circulation air inlet and can better stop the entrance of external dust.
Further, multiple outer circulation air outlet is set on the heat exchanger, it is possible to significantly more efficient power model is dispelled the heat.
Further, internal recycle heat dissipation channel and outer circulation heat dissipation channel are separated by internal recycle air channel, completely not by the impact of outer circulation heat dissipation channel when making internal recycle heat dissipation channel work independently.
Therefore DC charging device of the present invention can reduce the time that extraneous air directly exchanges, and decreases the entrance of dust so that reliability when equipment runs improves further, and decreases the maintenance work of Air Filter.
