Detailed description of the invention
Along with refrigeration system requirement is increased by people, automobile-used heating, ventilating and air conditioning system increase water valve device
Also will progressively introduce to the market, and i.e. be controlled the keying of warm-air drier temperature damper by micro machine or wire drawing driving lever, make hot engine water
Heat come out by the heat exchanger of warm-air drier and into the car, reach the effect of heating in car.
Heating installation in car is that the heat of the cooling water utilizing electromotor heats, although open summer is cold wind, but hot
The cooling water of heat still can circulate in radiator, namely just produces by boasting equal to after the cold air heating that air-conditioning is produced, that
Wind out certainly will not be the coldest, and consequence is just to increase oil consumption, reduces air-conditioning effect.The effect of this water-heating valve is exactly cold
But the repetend of water flows to beyond air conditioner heat radiator, allows hot water not enter driver's cabin with regard to direct circulation to electromotor, such cold wind
Would not be affected, leaving air temp is the lowest, and air-conditioning effect is all right, the most fuel-efficient.
Race of waiting for bus is hot, does not turn on the aircondition, and only position the coldest for temperature tune blue region, then opens fan, produces by boasting
Wind whether heat？Certainly, after having added water-heating valve, this wind would not be warm, but natural wind.The work of water-heating valve
With being that this.
Coil stator mentioned in the present invention is just in the pump housing of water-heating valve.
The pump housing 4: as depicted in figs. 1 and 2, including blade 400, brushless electric machine and obstruct cover 41, intercepts and is provided with in the middle part of cover 41
" U "-shaped accommodating cylinder 410, accommodating cylinder 410 opening part is provided with sealing ring limit 412.
Brushless electric machine: include that p-m rotor 401 and coil stator, p-m rotor 401 are embedded at accommodating cylinder 410 inwall, line
Delineation sub-set is located at accommodating cylinder 410 outer wall, and blade 400 is fixed on the surface of p-m rotor 401.
It is provided with installation room 51 in pump cover 5, in installation room 51, is provided with the circuit board of electric current, circuit in control coil stator
Plate is attached by electric conductor 6 with coil stator 42.
During use, p-m rotor 401 is positioned in accommodating cylinder 410, is provided with rotating shaft 411, p-m rotor in the middle part of accommodating cylinder 410
401 and/or blade 400 be articulated in rotating shaft 411.
Below in conjunction with the accompanying drawings the present invention is described further.
Coil stator: as shown in Figure 4, including the first steelframe 42A and the second steelframe 42B, the first steelframe 42A and the second steelframe
It is fixing that 42B cooperates for hot-wire coil winding, and produces common magnetic field on two steelframes, increases hot-wire coil pair
The magnetic attraction of p-m rotor.
-the first steelframe 42A: including annular underframe 421 and the some stators 420 installed for coil, stator 420 is vertical
Being fixed on annular underframe 421 surface, stator 420 prolongs annular underframe 421 and is uniformly distributed.
-the second steelframe 42B: including stator 420 and annular notched open loop underframe 422, stator 420 is vertically fixed
In open loop underframe 422 surface, stator 420 prolongs annular underframe 421 and is uniformly distributed, the stator 420 and second of the first steelframe 42A
Stator 420 setting interlaced with each other of steelframe 42B and contactless.
First steelframe 42A is for strengthening the electromagnetic field of hot-wire coil, and its annular underframe 421 uses the annular closed to be i.e. to use
In the magnetic field, magnetic field of coil being concentrated inside steelframe so that it is magnetic strength is more preferable.
Second steelframe 42B is then the structural strength for increasing steelframe, if the underframe in the second steelframe uses closed loop, then
Can form vortex ring in underframe, cancel out each other in the magnetic field forming the annular underframe 421 in the first steelframe 42A, therefore
The open loop underframe 422 of the second steelframe 42B, for carrying open loop structure jaggy, can effectively prevent eddy current from producing.
And the stator on two steelframes is the winding for solenoid, it is crisscross arranged and contactless, also for
Avoid eddy current to produce, and many materials can be saved, effectively reduce weight, make brushless electric machine no longer seem the heaviest.
First, second steelframe and stator thereon all use stalloy, and the ferrum of non-generic or steel, according to common
Steel or ferrum, during using for a long time, iron and steel can be magnetized and become permanent magnet, after causing electric current to magnetize when change direction
Iron and steel reaction relatively slow, therefore use the silicon steel material of demagnetic stack.
The most curved structure of stator 420 of the stator 420 and the second steelframe 42B of the first steelframe 42A, and first,
The stator 420 of two steelframes is respectively positioned in the annular surface with first-class circle, it is simple to the winding of hot-wire coil.
The stator 420 of first, second steelframe is the most triangular in shape or trapezoidal, it is contemplated herein that to owing to stator 420 is in punching
When backfin is curved, its structural strength is compared square the most firm, therefore the stator in the present embodiment uses triangle or trapezoidal.
Annular underframe 421 is provided with the enlarging 423 avoiding the second steelframe 42B stator 420 contact；On open loop underframe 422
It is provided with the enlarging 423 avoiding the first steelframe 42A stator 420 contact.At two, the position of enlarging 423 is just with on another steelframe
Stator position corresponding, it is therefore intended that avoid contact with, thus avoid eddy current to produce, eliminate local circulation magnetic field impact.
Breach 4220 is positioned in one of them enlarging 423 of open loop underframe 422, effectively utilizes space, if breach 4220 is opened
Between two enlargings 423, then structural strength will be substantially reduced.
The stator 420 that first steelframe 42A and the second steelframe 42B is staggered, adjacent stator 420 gap clearance is 2-
2.5mm.Consider that the purpose of gap clearance is to control the structural strength of two steelframes and the impact of stator bending.
If excesssive gap, then stator structural strength is not enough, pliable；If gap is too small, then stator is in bending
Shi Jiyi contacts each other, causes local circulation, it is therefore desirable to taking gap width is 2-2.5mm, and the gap width in the present embodiment is
2.2mm, each side ability is relatively mild.
Stator 420 on first steelframe 42A is one-body molded with annular underframe 421, and stator is stamped to form, the second steelframe
Stator on 42B is also.The thickness of annular underframe 421 is 0.8-1.2mm, and the thickness of annular underframe 421 is also 0.8-
1.2mm, the thickness taking the two in the present embodiment is 1mm.
The thickness of steelframe directly determines the overall weight of coil stator, the thinnest the lightest, it is contemplated that structural strength,
Therefore take 0.8-1.2mm thickness.
The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this
On the premise of bright principle, it is also possible to make some modification and improvement, these also should be regarded as protection scope of the present invention.
