Description
Technical field
The utility model relates to a kind of cooler, particularly relates to a kind of cooler of speed governing permagnetic synchronous motor.
Background technology
Synchronous machine is the same with induction machine is a kind of conventional alternating current machine.Synchronous machine is a kind of novel high-efficiency and energy-saving product, it possess the shape of high stability, high efficiency, simple in structure, motor and size can be versatile and flexible etc. remarkable advantage.Under synchronous machine normal operation, due to core loss, eddy current loss, mechanical loss etc., cause motor internal to produce heat, if can not dispel the heat in time, can have a huge impact motor body performance so.Along with the rising of frequency, large thereby the iron loss equal loss of motor also becomes thereupon, producing so very high heat will be very large on motor impact, and as heat increases, motor heats up affects insulation effect, produces potential safety hazard; Electric efficiency diminishes, and impact is normally worked.
The patent No. is that 200910223835.2 Chinese patent discloses kind cooling devcie of motor, mainly comprise cooler of electric motor, cooler of electric motor is communicated with wind path in motor, in cooler of electric motor, motor cooling water pipe is communicated with inlet box and air outlet box formation cooler of electric motor outer ventilation circuit, described cooling device also comprises collector ring cooler, in collector ring cooler, be provided with a dividing plate collector ring cooler inner chamber is separated into two chambers that top is communicated with, the bottom of two chambers is communicated with wind path in collector ring, some collector ring cooling water pipes vertically pass dividing plate and run through two chambers and are fixed in collector ring cooler, some collector ring cooling water pipes are communicated with air outlet box and form collector ring outer ventilation circuit.The utility model utilize two outer ventilation circuits respectively with motor in wind path cycle heat exchange in wind path and collector ring, significantly reduce motor and collector ring temperature rise, motor and collector ring are reliable, running noises is low, entirety good cooling results, the motor that can be widely used in external collector ring or other drive disk assemblies is cooling.The good type of cooling is very important for motor, and more conventional cooling means has the modes such as air cooling, hydrogen-cooled, water-cooled and oil cooling, but the aforesaid way inner and motor surface of cooling motor simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cooler of speed governing permagnetic synchronous motor, and it realizes and motor surface cool cooling to motor internal, improves cooling effect.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of cooler of speed governing permagnetic synchronous motor, it is characterized in that, it comprises that inlet channel, outlet conduit, fan, blower fan, air enter pipeline, Bas Discharged pipeline, evaporator, inlet channel, outlet conduit are all positioned at a side of evaporator, fan, air enter pipeline and are all connected with evaporator, Bas Discharged pipeline is connected with fan, and blower fan is positioned at a side of fan.
Preferably, the bottom of described evaporator is provided with first support, and fan is provided with second support.
Preferably, described evaporator is provided with the first dividing plate near near of inlet channel.
Preferably, described air enters pipeline and is provided with second partition, and Bas Discharged pipeline is provided with the 3rd dividing plate.
Positive progressive effect of the present utility model is: one, and in motor High Rotation Speed situation, the main loss of motor concentrates on iron loss, copper loss, as left not in time, motor internal temperature sharply rises, and after using this cooler, obtain ventilating rapidly cooling, arrived good cooling effect.Two, motor adopts variable frequency control, and rotating speed changes along with electric frequency change, and the iron loss of motor is also along with frequency variation in direct ratio, causes electric machine stand surface temperature to rise, and this cooler provides good surface cool for motor; Three, this cooler result is simple, easy maintenance, be easy to protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cooler of a kind of speed governing permagnetic synchronous motor of the utility model.
Embodiment
Provide preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the cooler of the utility model speed governing permagnetic synchronous motor comprises that inlet channel 1, outlet conduit 2, fan 3, blower fan 4, air enter pipeline 5, Bas Discharged pipeline 6, evaporator 7, inlet channel 1, outlet conduit 2 are all positioned at a side of evaporator 7, fan 3, air enter pipeline 5 and are all connected with evaporator 7, Bas Discharged pipeline 6 is connected with fan 3, and blower fan 4 is positioned at a side of fan 3.The bottom of evaporator 7 is provided with first support 11, and fan 3 is provided with second support 12, fixed like this.Evaporator 7 is provided with the first dividing plate 8 near near of inlet channel.Air enters pipeline 5 and is provided with second partition 9, and Bas Discharged pipeline 6 is provided with the 3rd dividing plate 10.By above-mentioned three dividing plates respectively to evaporator, air enter pipeline, Bas Discharged pipeline is controlled.
Water enters from inlet channel, by evaporator, is dispelled the heat with cooling in motor surface, and fan and blower fan can blow motor internal cooling.In motor High Rotation Speed situation, the main loss of motor concentrates on iron loss, copper loss, and as left not in time, motor internal temperature sharply rises, and after using this cooler, has obtained ventilating rapidly cooling, has arrived good cooling effect.Motor adopts variable frequency control, and rotating speed changes along with electric frequency change, and the iron loss of motor is also along with frequency variation in direct ratio, causes electric machine stand surface temperature to rise, and this cooler provides good surface cool for motor; This cooler result is simple, easy maintenance, be easy to protection.Using before this cooler, first checking the situation of complete cooling system, whether well-ventilated of each pipeline; Secondly, check whether each junction occurs leaking out, drainage; Finally, start trial run, checks that whether working condition is good, and then is connected with motor, waits for and the operation of motor co-operation.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect to solution of the present utility model further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
