Embodiment
As shown in Fig. 1 to Fig. 5, anti-dewfall structure inside a kind of frequency converter, it includes frequency converter 1, the installation of 1 sidepiece of frequency converter
There is heat dissipation dehydrating unit 2, heat dissipation dehydrating unit 2 includes heat exchange cabinet 3, is provided with heat exchanger 4 inside the cabinet 3 that exchanges heat, is set on heat exchanger 4
Cooling liquid outlet 5 and cooling liquid inlet 6 are equipped with, cooling liquid inlet 6 connects external heat-exchanging device 7, and heat exchange cabinet 3 connects with frequency converter 1
The side wall for connecing side is provided with the air inlet and air outlet of corresponding heat exchanger 4, and air inlet is provided with two rows of extractor fans 8, outlet air
Several rows of wind fan 9 is provided with mouthful, heat exchange cabinet 3 is interior to be separated out the inlet air cavity 11 of corresponding air inlet by partition plate 10, corresponds to
The air-out cavity 12 of air outlet, cooling liquid outlet 5 connect the dispenser 13 inside frequency converter 1, and dispenser 13 is by flowing through power
The cooling line 15 of device 14 connects liquid trap 16, and liquid trap 16 connects external heat-exchanging device 7.
Radiating fin 17 is installed, 4 lower end of heat exchanger is provided with condensate collector 18, condensation water collection on heat exchanger 4
Device 18 for upper end opening and the collection vessel that is in tilted layout, collection vessel, which tilts, to be provided with condensed water on the side wall of lower end side and goes out
Mouth 19,3 bottom of heat exchange cabinet are provided with the discharge outlet 20 of corresponding condensation-water drain 19, and heat exchanger 4, which tilts, is installed on heat exchange 3 side wall of cabinet
On inclined plate 21, condensed water can be preferably set to flow into condensate collector 18；Air outlet is located above air inlet, due to cold sky
Gas is than hot-air weight so that the low temperature dry air of discharge can be preferably to cooling down in cabinet.3 top of heat exchange cabinet is provided with
Supply unit 22.
Operation principle：Hot and humid air in frequency converter is entered under the heat exchanger 4 in heat exchange cabinet 3 by extractor fan
Portion, carries out heat exchange, and hot and humid air runs into the cooling line of low temperature, and heat, which can be discharged into, is transferred to the cold of inside on pipeline
But liquid, so as to reduce air themperature, due to being hot and humid air, to the cold after can produce condensation, in air
It is that humid air can become condensed water, so as to reduce air humidity, discharges and be sent into frequency converter by air ejector fan 6, cryogenic liquid
The geothermal liquid in being formed after above-mentioned heat exchange, middle geothermal liquid flow to the heat sink of power device 14, with height by dispenser
The power device heat exchange of temperature, allows power device 14 to be operated in the state of low temperature, becoming high-temp liquid after medium temperature liquid heat exchange leads to
Cross liquid trap exclusion.Temperature of the rise into transducer power device liquid.
By both the above method, the cabinet of frequency converter is set to become the environment of low temperature drying, under such a environment, the work(in cabinet
Rate device can inherently generate heat, and temperature can be far above the environment temperature in cabinet, avoid the condensation of device in cabinet.Cryogenic liquid becomes
Middle geothermal liquid so that environment temperature in the fluid pipeline and cabinet in cabinet, the temperature difference are substantially reduced, since cabinet humidity is relatively low so that
Dew-point temperature is significantly relatively low, and pipe surface temperature is more than dew-point temperature, so as to avoid, the dew condensation phenomenon of fluid pipeline.
