Drawings
Fig. 1 is a schematic structural diagram of a variable frequency electrical cabinet air conditioner of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1, the present embodiment provides a variable-frequency electrical cabinet air conditioner, including a housing 1, a first chamber 11 and a second chamber 12 partitioned by a thermal baffle 2 and disposed in the chambers of the housing 1, an electric control device disposed in the first chamber 11, and a refrigeration device disposed in the second chamber 12; the heat insulation plate 2 is provided with a vent 21, and a filter screen 3 for preventing condensed water in the second chamber 12 from flowing into the first chamber 11 is arranged at the vent 21; the first chamber 11 and the second chamber 12 are communicated through the filter screen 3; the refrigeration device comprises an evaporator 41 connected with the compressor, and a fan 42 erected in the second chamber for forming negative pressure in the second chamber 12; the second chamber 12 is provided with a drain pipe 5 for discharging condensed water, an air inlet 13 is formed in the wall of the second chamber on one side of the evaporator 41, and further the second chamber is provided with a waterproof breathable film on the periphery of the first chamber and the second chamber, in the embodiment, the filter screen 3 is provided with a waterproof breathable film and is arranged on one side of the vent close to the second chamber.
In addition, in the present embodiment, in order to prevent the temperature difference between the first chamber and the second chamber from generating condensed water on the inner wall of the first chamber, the first chamber 11 in the above embodiment is configured as a heat preservation chamber.
In this embodiment, the air outlet direction of the fan 42 is opposite to the air vent 21, and the electric control device is configured as a control board 51 and a power board 52.
Adopt above-mentioned structural design's inverter type regulator cubicle air conditioner, hot-air in first cavity flows in the second cavity after through filter screen 3, under the vortex effect that produces between fan and heat insulating board for produce certain negative pressure in the second cavity, also make fully exchange between hot-air and the cold air simultaneously, produce the comdenstion water and discharge through drain pipe 5, cold wind also can flow in first cavity through the filter screen simultaneously, effectively cool down to its inside control panel 51 and power strip 52.
