Abstract
The utility model discloses a frequency conversion cabinet comprises a cabinet body and a frequency converter. The frequency converter is fixed in the cabinet body via an installing plate. The bottom of the cabinet body is provided with a ventilation filter assembly. The frequency converter itself has an axial flow fan and a heat sink. The top of the cabinet body is also provided with an auxiliary axial flow fan. The top of the frequency converter is provided with an exhaust pipe. The inlet of the exhaust pipe communicates with the frequency converter, and the outlet of the exhaust pipe communicates with the outside. The outer side of the cabinet body further provided with a temperature and humidity regulator. The frequency converter, the auxiliary axial flow fan and the temperature and humidity regulator are in signal communication. Through arrangement of a dedicated hot air channel and the temperature and humidity regulator, the heat dissipating efficiency and effects can be effectively improved, failure due to over high temperature in the cabinet body is avoided, the life cycle of equipment is effectively extended, and the working environment of the equipment is improved.
Description
Technical field
The utility model belongs to electrical apparatus control equipment field, particularly a kind of frequency conversion tank of good heat dissipation effect.
Background technology
Along with country and enterprise constantly deepen the understanding of energy conservation theory, the effect of frequency converter and use have obtained great popularization, by frequency converter, can effectively reduce energy resource consumption, reducing cost drops into, frequency converter all will be placed in cabinet while using, cabinet is a comparatively space for sealing, and the components and parts of frequency converter inside are as IGBT, reactors etc. are all the large parts of heating, frequency converter uses for a long time, the heat that components and parts produce is spent accumulation more and can not be distributed timely and effectively, can produce a lot of secondary disasters, the lighter causes components and parts to burn scrapping, frequency converter can not use, severe one possibility initiation fire, this just gives us routine use, production brings very big inconvenience and hidden danger, in order better to use frequency converter, just need to process its suitable cooling, the most traditional is exactly to pass through natural wind, the modes such as wind is loose are dispelled the heat, this traditional approach radiating effect is not obvious, radiating efficiency is low, also occurred afterwards dispelling the heat by axial flow blower, as Chinese patent literature CN201869088U discloses a kind of frequency conversion tank, comprise cabinet, frequency converter, the control section of frequency converter is placed in the front portion of cabinet, the fin section of frequency converter and axial flow blower are placed in the rear portion of cabinet, before and after have demarcation strip between two, this mode can improve certain radiating effect, but effect is also unconspicuous, also have directly by air-conditioning room temperature lowering, this cooling method electric energy expends greatly, cost is high, be not suitable for promoting the use of.
The technical problems to be solved in the utility model be to provide a kind of simple in structure, use cost is low, the new type inverter of good heat dissipation effect.
Utility model content
For solving above-mentioned prior art processed complex, use inconvenient, the easy problem such as scatter, the utility model adopts following technical scheme:
The utility model provides a kind of frequency conversion tank, comprise cabinet and frequency converter, described frequency converter is fixed in described cabinet by mounting panel, at described bottom of cabinet bulk, be provided with ventilation filter assembly, described frequency converter carries axial flow blower and fin, at described cabinet top, be also provided with asessory shaft flow fan, described frequency converter top is provided with exhaust duct, described exhaust duct air inlet is communicated with described frequency converter, described exhaust duct air outlet is communicated with outdoor, in described cabinet outside, be also provided with thermo hydrograph regulator, described frequency converter, asessory shaft flow fan, mutual signal communication between thermo hydrograph regulator.
The beneficial effects of the utility model are: by special-purpose hot-air channel and thermo hydrograph regulator are set, can effectively improve radiating efficiency and effect, prevent that excess Temperature produces fault in cabinet, the effective life cycle of extension device, has improved the operational environment of equipment.
Accompanying drawing explanation
Fig. 1 is left view of the present utility model.
Fig. 2 is front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
Refer to Fig. 1, Fig. 2, a kind of frequency conversion tank, comprise cabinet 1 and frequency converter 2, described frequency converter 2 is fixed in described cabinet 1 by mounting panel, in described cabinet 1 bottom, be provided with ventilation filter assembly 11, described frequency converter 2 carries axial flow blower 21 and fin (invisible in figure), at described cabinet 1 top, be also provided with asessory shaft flow fan 3, described frequency converter 2 tops are provided with exhaust duct 4, described exhaust duct 4 air inlets are communicated with described frequency converter 2, described exhaust duct 4 air outlets are communicated with outdoor, in described cabinet 1 outside, be also provided with thermo hydrograph regulator 5, described frequency converter 2, asessory shaft flow fan 3, mutual signal communication between thermo hydrograph regulator 5, frequency conversion tank in use, air enters in cabinet 1 from ventilation filter assembly 11, guarantee that like this air entering cleans, the axial flow blower 21 that frequency converter 2 carries will output to cabinet 1 top through fin the cold air entering, the hot-air at cabinet 1 top is just smoked by the asessory shaft flow fan 3 increasing, and be discharged to outdoor through exhaust duct 4, the heat producing so can not be diffused into cabinet 1 other regions with regard to direct discharge, during chosen axis flow fan, the flow of asessory shaft flow fan 3 must frequency converter 2 to carry axial flow blower 21 large, can guarantee that like this hot-air is not stranded in cabinet 1, the function of thermo hydrograph regulator 5 is just similar to a little air-conditioning, thermo hydrograph regulator 5 guarantees that by interior circulation the outside cabinet internal temperature of frequency converter is unlikely to too high, the startup of thermo hydrograph regulator 5 and asessory shaft flow fan 3, stop synchronizeing with frequency converter, when not moving, frequency converter just not can not produce heat, thermo hydrograph regulator 5 and asessory shaft flow fan 3 are worked as required, the corresponding reduction of use cost, saved electric energy, by above-mentioned improvement, improve greatly the heat radiation of frequency conversion tank, effectively extend the life cycle of frequency conversion tank, simple in structure, scrap build cost is low.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
