Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The compressor 100 according to the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Shown in seeing figures.1.and.2, comprise housing 1 and motor 2 according to the compressor 100 of the embodiment of the present invention.Motor 2 is located in housing 1, limits gas channel 8 between the outer surface of motor 2 and the internal surface of housing 1.What limit the outer surface of the motor 2 of gas channel 8 and the internal surface of housing 1 is provided with oleophobic coating 7 at least partially.
According to the compressor 100 of the embodiment of the present invention, by arranging oleophobic coating 7 at least partially what limit the outer surface of motor 2 of gas channel 8 and the internal surface of housing 1, oleophobic coating 7 significantly can reduce the suction-operated of gas channel 8 pairs of lubricant oil, reduce viscous resistance, thus the exhaust resistance that effectively reduction gas is produced by motor 2 is lost, and improves the efficiency of compressor 100.Meanwhile, owing to there is not the viscous resistance of housing 1 and motor 2 in the lubricant oil of motor 2 upper space, oil return speed will be accelerated, and improves stator 22 top and amass oily problem, improves the reliability of compressor 100.
Be understandable that, according to embodiment of the present invention compressor 100 can be comprise housing 1 and motor 2 and make the space between housing 1 and motor 2 be any one compressor of exhaust and grease channel, such as rotary compressor, piston compressor, rolling rotor type compressor, scroll compressor and turn cylinder compressor etc.
In the embodiment shown in fig. 1 and 2, the compressor 100 according to the embodiment of the present invention is formed as rotary compressor.For this compressor 100, the present invention is described in detail below.Specifically, compressor 100 comprises the housing 1 for sealing, and is arranged on the compression assembly 3 in housing 1 and electric machine assembly, and the motor 2 in electric machine assembly comprises stator 22 and rotor 21.Stator 22 is provided with stator 22 through hole, and rotor 21 is located in stator 22 through hole and rotor 21 can pivotable.
Compression assembly 3 is positioned at the below of electric machine assembly and is connected with motor 2 by bent axle 6.Motor 2 is with dynamic crankshaft 6 to rotate, and realizes compression assembly 3 and sucks refrigerant and the action such as compression, exhaust from liquid-storage container 4, and the refrigerant that compression chamber is discharged enters the space of motor 2 and compression assembly 3 by the exhaust port of baffler.Refrigerant, after being in cooling motor 2 lower end, entering above housing 1 by motor 2, cools the upper end of motor 2.After eventually passing Oil-gas Separation, refrigerant discharges compressor 100 by outlet pipe 5.
It should be noted that the pressurized gas of discharging from compression chamber and not all is refrigerant, wherein also containing a large amount of refrigeration lubrication oil (abbreviation refrigeration oil).This part refrigeration oil comprises the refrigeration oil sucked from liquid-storage container 4 and the refrigeration oil entering compression chamber from compression chamber External leakage.After this partial freeze oil enters compression chamber, be mixed into high pressure refrigerant with the form of mist of oil.The gas mixture be made up of refrigerant and refrigeration oil is discharged to the lower space of motor 2 jointly.
Meanwhile, the refrigerant entering housing 1 space also may impact the oil return in housing 1 or the refrigeration oil in oil sump, causes two sub-band oil.But, air-conditioning system does not wish that the refrigeration oil in compressor 100 enters air-conditioning duct, therefore, in compressor 100, is provided with gas and oil separating plant, refrigeration oil was separated with refrigerant before discharging compressor 100 housing 1 along with refrigerant, and falls back in the bottom oil sump of compressor 100.
In above-mentioned compressor 100 exhaust process, because motor 2 takies most space in the middle part of housing 1, the rotor 21 of motor 2 is in High Rotation Speed state in addition, and the gas mixture of discharging from compression assembly 3 can not enter housing 1 upper space smoothly.In the related, because motor sidewall is to the suction-operated of refrigeration oil, exhaust is reduced further in the flowing velocity near motor sidewall, and the exhaust resistance of compressor increases further, and void has consumed compressor power consumption.
And according in the compressor 100 of the embodiment of the present invention, said process obtains obvious improvement.That is, by the outer surface of motor 2 and the internal surface of housing 1 at least partially on apply oleophobic coating 7, the adsorption force that gas channel 8 pairs of gas mixtures produce reduces, and reduces exhaust resistance, improves the efficiency of compressor 100.
Meanwhile, the gas mixture of motor 2 upper space is after being separated, and refrigeration oil will fall to the bottom oil sump of compressor 100 from the upper end of stator 22 along housing 1 and stator 22 wall.Refrigeration oil herein will be subject to the percussion of lower exhaust.In the related, because housing and stator sidewall are to the suction-operated of refrigeration oil, oil return will become slowly, and What is more, and most of refrigeration oil is accumulated in stator top, cause the long-pending oil in stator top, have impact on compressor reliability.And according in the compressor 100 of the embodiment of the present invention, due to the effect of oleophobic coating 7, the side wall surface of the stator 22 of housing 1 and motor no longer will produce viscous to refrigeration oil, oil return can be accelerated, improve the reliability of compressor 100.
Wherein, oleophobic coating 7 can only be located on the internal surface of housing 1, or oleophobic coating 7 is located on the outer surface of motor 2, or the internal surface of the outer surface of motor 2 and housing 1 is equipped with oleophobic coating 7.The compressor 100 of this kind of structure can reduce the exhaust resistance of gas mixture greatly, significantly improves the efficiency of compressor 100.
It should be noted that, due to the main space that housing 1 upper space is Oil-gas Separation, and utilize housing 1 surface to be also the important means of housing 1 top Oil-gas Separation to the suction-operated of refrigeration oil, therefore, in order to avoid affecting the oil gas separation on housing 1 top, the level height of the oleophobic coating 7 of the internal surface of housing 1 can be less than or equal to the maximum horizontal height that motor 2 coordinates with housing 1.Thus, the viscous resistance that gas mixture is subject in gas channel 8 is little, and after outflow gas channel 8, the top of housing 1 has suction-operated to refrigeration oil, makes refrigeration oil also be easy to be separated with refrigerant.
As shown in Figure 2, form gap between the internal surface of stator 22 and the outer surface of rotor 21, the internal surface of stator 22 and/or the outer surface of rotor 21 are provided with oleophobic coating 7.Namely the internal surface of stator 22 is provided with oleophobic coating 7, or the outer surface of rotor 21 is provided with oleophobic coating 7, or the internal surface of the outer surface of rotor 21 and stator 22 is equipped with oleophobic coating 7.The internal surface of outer surface and/or stator 22 that this oleophobic coating 7 significantly can reduce rotor 21 equally, to the suction-operated of lubricant oil, reduces viscous resistance, gas mixture is easier to by motor 2 inner.
In examples more of the present invention, rotor 21 and/or stator 22 are provided with vent slot, and the side wall surface of vent slot is provided with oleophobic coating 7.This oleophobic coating 7 can reduce the suction-operated of side wall surface to lubricant oil of vent slot equally, reduces viscous resistance, makes the inside that gas mixture is easier to by rotor 21 and/or stator 22.
Alternatively, oleophobic coating 7 can be resin material layer or ceramic material layer or surface modifying material layer.Be understandable that, as long as make the wall of gas channel 8 have thin oil properties to compressor 100 refrigeration oil used, all can become the material of the oleophobic coating 7 of the compressor 100 according to the embodiment of the present invention.
Wherein, according to the difference of cladding material formation process, oleophobic coating 7 thickness can change between 0.5 μm to 500 μm.Particularly, the coating processes of oleophobic coating 7 can adopt the kinds of processes such as sedimentation, etching method, spraying method and gel method according to the difference of cladding material.
As shown in Figure 3, the oleophobic properties of solid surface characterizes with wrapping angle θ usually.The ideal solid surface contact angle of smooth, all even isotropic should meet Young`s equation:
cosθ＝(γ
SV-γ
SL)/γ
LV
In formula, θ is wrapping angle, and Υ is interfacial tension, and subscript S, L and V represent solid phase, liquid and gas respectively.Wrapping angle θ is the result of surface free energy thermodynamical equilibrium between solid, liquid, gas interface.Therefore, θ is also called equilibrium contact angle, or claims the intrinsic wrapping angle of material.
But actual solid surface is all coarse, and the degree of roughness on surface is often also uneven, as shown in Figure 4.The apparent contact angle of the rough surface under Cassie model can represent with following formula:
cosθ
c＝f
1cosθ-f
2
Wherein θ
cfor the apparent contact angle under Cassie model.This formula can change into f further
1ratio shared by solid-liquid interface, f
2ratio shared by liquid-gas interface, so this formula can be further converted to:
cosθ
c＝r
ffcosθ+f-1
Wherein, f is the ratio that drop soaks the area of contour of solid surface, r
ffor drop soaks the roughness ratio of solid surface.
Above formula shows, the lyophilic material of intrinsic wrapping angle θ < 90 ° also can make lyophobic surface, by constructing rational microstructure, obtains rational f and r
fvalue, can θ be made
c> 90 °, makes solid surface have lyophoby character.According in the compressor 100 of the embodiment of the present invention, namely oleophobic coating 7 is configured to compressor 100 refrigeration oil and is greater than 90 ° at the wrapping angle on the surface of oleophobic coating 7, thus makes oleophobic coating 7 pairs of refrigeration oils have oleophobic properties.
In addition, except wrapping angle, roll angle is also weigh an index of solid hydrophobic surface oleophobic performance.So-called roll angle just refers to that, when slow inclination solid surface, drop has just started to tumble in a flash, the inclined angle alpha between solid surface and horizontal basal plane, as shown in Figure 5.In compressor 100, exhaust passage is generally vertical, and therefore, almost can not consider roll angle when designing oleophobic coating 7, this will provide great convenience to Material selec-tion.
Condenser, vaporizer and the compressor 100 etc. according to the embodiment of the present invention is comprised according to the chiller plant of the embodiment of the present invention.Owing to there is above-mentioned useful technique effect according to the compressor 100 of the embodiment of the present invention, therefore according to the efficiency of the chiller plant of the embodiment of the present invention and reliability high.
