Abstract

The utility model discloses a water-cooled high-voltage frequency converter unit cabinet with an auxiliary heat radiation apparatus. The water-cooled high-voltage frequency converter unit cabinet comprises a frequency converter housing (1), a plurality of power units (2), a cold-hot air isolation baffle plate (3), an empty-water heat exchanger (4), a cold water outlet (5) of the empty-water heat exchanger, a hot water outlet (6) of the empty-water heat exchanger, an empty-water cold-hot exchange zone (7), a circulation blower fan (8), a hot air zone (9) and a cold air zone (10). An auxiliary heat radiation apparatus provides auxiliary heat radiation for small electronic components, conducting wires and joints in the frequency converter unit during working, and eliminates negative pressure in the cabinet during normal operation of the frequency converter. In this way, dust can not enter into the frequency converter, and failure rate of the frequency converter is lowered.

Description

A kind of water-cooled high voltage converter unit cabinet that installs auxiliary radiating device additional
Technical field
The utility model belongs to the high-pressure frequency-conversion field, is specifically related to a kind of water-cooled high voltage converter unit cabinet that can carry out auxiliary heat dissipation to the heat that the Small electronic component in the unit, lead and joint produce at work.
Background technology
Known water-cooled type frequency convertor is that its power cell fin air-cooled radiator is replaced with water-filled radiator, utilizes recirculated water that the exchange heat that main heater element such as IGBT, rectifier bridge produces is gone out.And the heat that the Small electronic component of inside, unit (electrochemical capacitor, resistance), lead and joint produce at work continues to discharge outdoor with traditional cooling fan, so just can't guarantee the sealing of unit cabinet, cause dust constantly to enter frequency converter, will destroy the insulation of frequency converter, thereby increase the failure rate of frequency converter.
Summary of the invention
Goal of the invention: design a kind of water-cooled high voltage converter unit cabinet, can carry out auxiliary heat dissipation to the heat that the Small electronic component in the frequency converter unit, lead and joint produce at work, do not have negative pressure in the cabinet in the time of making the frequency converter operate as normal again, reach the purpose that dust can't enter frequency converter inside.
Technical scheme: a kind of water-cooled high voltage converter unit cabinet that installs auxiliary radiating device additional, comprise that frequency converter shell 1, some power cells 2, cold-hot wind isolation baffle plate 3, sky-water-to-water heat exchanger 4, sky-water-to-water heat exchanger enter cold water outlet 5, sky-water-to-water heat exchanger hot-water outlet 6, sky-water-cooled heat exchange zone 7, circulating fan 8, hot blast district 9, cold wind district 10, it is characterized in that power cell 2, cold-hot wind isolation baffle plate 3, sky-water-to-water heat exchanger 4, circulating fan 8, hot blast district 9, cold wind district 10 all are positioned at airtight frequency converter shell 1 inside; Cold-hot wind is isolated baffle plate 3 space in the frequency converter shell 1 is separated into hot blast district 9, cold wind district 10; Positioned beneath sky-water-to-water heat exchanger 4 and circulating fan 8 at power cell 2; Sky-water-to-water heat exchanger advances cold water outlet 5, sky-water-to-water heat exchanger hot-water outlet 6 is installed in respectively on sky-water-to-water heat exchanger 4, is connected on respectively on the high-voltage tube and low pressure pipeline of recirculated water, circulates continuously, carries out the cold-hot exchange; Below sky-water-to-water heat exchanger 4, there is a sky-water-cooled heat exchange zone 7;
Operation principle: during the frequency converter operate as normal, the heat that main heating such as its IGBT, rectifier bridge components and parts produce is by water-cooled exchange (be current techique, be not discussed here).As shown in Figure 1, isolate under the effect of baffle plate 3 at circulating fan 8 and cold-hot wind, air can form a circulating current continuously along the direction of arrow in the frequency converter unit cabinet; Also can produce less heat in some Small electronic component (as electric capacity, resistance, inductance etc.) work in the power cell 2, this heat can't be taken away under above-mentioned water-cooled condition, dirty in hot blast district 9 in the effect of circulating current, cool off at sky-water-cooled heat exchange zone 7 through sky-water-to-water heat exchanger 4, cooled air flow to cold wind district 10, pass a plurality of power cells 2 respectively, take described heat to hot blast district 9 again, go round and begin again.
Advantage of the present utility model and beneficial effect: the utility model is by installing auxiliary radiating device additional, can carry out auxiliary heat dissipation to the heat that the Small electronic component in the frequency converter unit, lead and joint produce at work, do not have negative pressure in the time of making the frequency converter operate as normal again in the cabinet, reach the purpose that dust can't enter frequency converter inside, reduce the frequency converter failure rate.
