Description
Technical field
The present invention relates to a kind of flow channel type mine-used frequency-converter housing.
Background technology
In recent years, converter is widely used in industrial and mining establishment, and motor and conventional apparatus are carried out speed regulating control.Converter to produce certain power consumption in running, and is converted into heat.Its power consumption is generally the 4 ~ 5% of its capacity.For ensureing the normal work of converter, converter must the reliable heat abstractor of matching performance.The radiating mode that converter uses has forced air cooling, water-cooled, natural heat dissipation.Forced air cooling needs draught fan matching and radiator simultaneously.Manufacturing cost is higher.But, good heat dissipation effect, thus, become the most commonly used a kind of radiating mode.Water-cooled is a kind of mode that industry cooling is more common.Its cost is high, and volume is big, only just adopts in this way at the king-sized converter of special occasions and capacity.Natural heat dissipation mode typically selected by converter for low capacity, and natural cooling is to design radiating ribs or vent window on frequency converter shell, simple in construction, but, it uses environment to answer well-ventilated, without easily attachment dust and drift.
For the converter that mine fan is supporting, it is desirable to have explosion-proof (flame proof) requirement.Use traditional structure, be designed to independent converter, be arranged in mine laneway, limited by mine laneway space, inconvenience is installed.In addition, by high humidity in tunnel, the objective factors such as dust is many affect, and its operational reliability is poor.Because its working condition is sufficiently complex, the radiating mode of converter also has higher requirement, and water-cooling pattern wants supporting circulating water pipe and radiator, also takes up room.Using natural heat dissipation mode, frequency converter shell is the most airtight, meets requirement of explosion proof, it is to avoid electric elements inside and contacting external air, can not use again traditional aluminium radiating device, thus, its radiating effect can not be guaranteed again.
Summary of the invention
It is an object of the invention to provide in a kind of runner being built in ventilating system, simple in construction, practicality, the flow channel type frequency converter shell of good heat dissipation effect.
