The compressor assembly 100 of embodiment is according to a first aspect of the present invention described below with reference to Fig. 1-Figure 10.
As Figure 1-Figure 5, the compressor assembly 100 of embodiment according to a first aspect of the present invention, comprises compressor and loop circuit heat pipe 4.Wherein, compressor can be rotary compressor.In description below the application, take compressor as rotary compressor for example is described.Certainly, those skilled in the art are appreciated that compressor can also be the compressor of other type, and are not limited to rotary compressor.
Compressor such as rotary compressor comprises housing 11, motor 21 and compressing mechanism, and motor 21 and compressing mechanism are all located in housing 11, and motor 21 is connected with compressing mechanism.When motor 21 works, compressing mechanism can compress the refrigerant entered in it.Specifically, compressing mechanism comprises main bearing 31, cylinder assembly, supplementary bearing 33, slide plate 36, piston 35 and bent axle 34, main bearing 31 and supplementary bearing 33 are located at the axial two ends of cylinder assembly, one end of bent axle 34 (such as, upper end in Fig. 1 with Fig. 2) be connected with the rotor of motor 21, the other end of bent axle 34 (such as, lower end in Fig. 1 and Fig. 2) through main bearing 31, cylinder assembly and supplementary bearing 33, cylinder assembly comprises at least one cylinder 32, it is outer and be positioned at cylinder 32 that piston 35 is set in bent axle 34, cylinder 32 is formed with the vane slot 324 for holding slide plate 36, slide plate 36 to be located at movably in vane slot 324 and innerly only to support with piston 35, cylinder 32 has intakeport 321 and relief opening 322, intakeport 321 and relief opening 322 lay respectively at the both sides of vane slot 324.Here, it should be noted that, direction " interior " can be understood as towards the direction at cylinder 32 center, and its opposite direction is defined as " outward ", namely away from the direction at cylinder 32 center.
When compressor such as rotary compressor work, the rotor banding dynamic crankshaft 34 of motor 21 rotates, the piston 35 be set in outside the eccentric part 341 of bent axle 34 can roll along the inwall of the compression chamber 322 of cylinder 32, thus to compressing from intakeport 321 refrigerant entered in compression chamber 322 and the refrigerant after compression being discharged from relief opening 322.
According to a concrete example of the present invention, with reference to Fig. 1 composition graphs 2, cylinder assembly comprises a cylinder 32, and main bearing 31 is located at the upper end of this cylinder 32 and supplementary bearing 33 is located at the lower end of this cylinder 32, and now compressor such as rotary compressor is single cylinder compressor.Certainly, when cylinder assembly comprises multiple cylinder 32, can be separated between adjacent two cylinders 32 by dividing plate, now compressor such as rotary compressor is multicylinder compressor.
As shown in Figure 4, loop circuit heat pipe 4 comprises vaporizer 41, condenser 42, first flow path 43 and the second stream 44, vaporizer 41 is established on the compressor, and condenser 42 is communicated with vaporizer 41 fluid by first flow path 43, and condenser 42 is communicated with vaporizer 41 fluid by the second stream 44.Wherein, have the working medium for heat exchange in loop circuit heat pipe 4, alternatively, working medium is R717, R718, HCFC, CFC, HFC or HC etc., but is not limited thereto.
When compressor such as rotary compressor work, compressor generates heat, the liquid refrigerant flowing through vaporizer 41 can carry out heat exchange with compressor, to cool compressor, liquid refrigerant after heat exchange is transformed into gaseous state, and by the second stream 44 (for convenience of description, claim gas flow path hereinafter) flow to condenser 42, gaseous working medium is condensed into liquid state in condenser 42, again vaporizer 41 is flowed back to, to continue to cool compressor again by first flow path 43 (claiming liquid flow path hereinafter).
With reference to Fig. 4 composition graphs 5, loop circuit heat pipe 4 (LoopHeatPipe) is a kind of high-efficiency heat transfer device of two-phase, it is that the capillary force utilizing the capillary core in vaporizer 41 to produce drives the whole loop of loop circuit heat pipe 4 to run, the evaporation of the working medium in it and condensation is utilized to carry out transferring heat, therefore, it is possible to transmit a large amount of heats when the little temperature difference, long distance.
Vaporizer 41 is core components of loop circuit heat pipe 4, and as shown in Figure 5, vaporizer 41 is made up of evaporator shell 411, gas conduit 4111, liquid-sucking core and the liquid inlet pipe 415 be formed on evaporator shell 411 inwall from outside to inside.Wherein, liquid-sucking core can comprise main liquid-sucking core 412 and time liquid-sucking core 413, main liquid-sucking core 412 is formed as annular shape, multiple times liquid-sucking core 413 (does not have secondary liquid-sucking core 413 in the vaporizer 41 of some loop circuit heat pipe 4, and in cistern 45, have secondary liquid-sucking core 413) to be located in main liquid-sucking core 412 and interval is arranged in the circumferential, limit fluid passage 414 between adjacent two liquid-sucking cores 413.Main liquid-sucking core 412 is high performance capillary core, and the hole of main liquid-sucking core 412 is very tiny, and enough capillary pressures can be provided like this to ensure the carrying out of circulating.The aperture of secondary liquid-sucking core 413, compared with main liquid-sucking core 412, is larger, is conducive to liquid refrigerant like this and flows to vaporizer 41.
The diabatic process of loop circuit heat pipe 4 is: when evaporator shell 411 is heated, heat passes to liquid-sucking core surface by the conductive force of evaporator shell 411, and the temperature on liquid-sucking core surface can raise (heat still can be transmitted toward vaporizer 41 center by liquid-sucking core surface simultaneously).When liquid-sucking core near surface temperature reaches the saturation temperature of working medium, liquid refrigerant can be made to evaporate, so just make liquid-sucking core near surface produce an obvious two-phase section.Liquid refrigerant, while evaporation, produces capillary force by the hole acting in conjunction of working medium surface tension and liquid-sucking core, thus makes the pressure of steam in vaporizer 41 higher than the pressure of the miscellaneous part of loop circuit heat pipe 4.Thus, the effect of capillary force promotes whole loop circuit heat pipe 4 and circulates just.
Condenser 42 is another vitals of loop circuit heat pipe 4, passes to heat sink by the heat that vaporizer 41 absorbs, and is connected between vaporizer 41 with condenser 42 by gas flow path with liquid flow path.Wherein, condenser 42 can utilize natural heat dissipation, also can increase fan and carry out forced-convection heat transfer, but be not limited thereto.
Further, as shown in Figure 4, loop circuit heat pipe 4 comprises further: cistern 45, and cistern 45 is located in first flow path 43 (i.e. liquid flow path), and is positioned at the side of the contiguous vaporizer 41 of liquid flow path.Wherein, cistern 45 can become one with vaporizer 41, and the inner time liquid-sucking core 413 that passes through is connected with vaporizer 41.Thus, by arranging cistern 45, liquid refrigerant can be stored in cistern 45, such as, when compressor heating value is larger, the liquid refrigerant in cistern 45 can be made all to participate in circulation, when compressor heating value is less, can only make a part of liquid refrigerant in cistern 45 participate in circulation.
From the above, the operation of loop circuit heat pipe 4 is power-actuated by capillary.The pressure difference produced by capillary core is:
ΔP
cap＝2σ/r(1)
In formula, σ is the surface tension of working medium, N/m;
R is the radius of curvature in liquid-sucking core, m.
Mass flow rate and the loss of total pressure of circulation increase, until loss of total pressure exceedes the maximum capillary pressure of liquid-sucking core along with the increase of vaporizer 41 load.Liquid-sucking core can produce maximum capillary force:
In formula, R
pit is the aperture of porous medium;
θ is the wrapping angle of liquid and liquid-sucking core.
If maximum capillary pressure equals total system pressure loss, so continue the thermal force increasing vaporizer 41, steam will be caused to infilter liquid-sucking core, and finally cause system out of service.Therefore, under normal operation, for a complete loop circuit heat pipe 4 circulates, the capillary pressure that the main liquid-sucking core 412 of vaporizer 41 provides must can overcome the pressure loss of circulation, and the overall presure drop of the whole circulatory system is made up of all parts internal pressure loss respectively: loss and other hydrostatic pressures losses caused by gravity that gas conduit 4111 internal pressure loss, steam pipe line internal pressure loss, condenser 42 internal pressure loss, liquid line internal pressure loss, vaporizer 41 liquid-sucking core internal pressure loss etc. of vaporizer 41 cause by rubbing.System must meet following formula:

So, according to the working principle of above-mentioned loop circuit heat pipe 4, loop circuit heat pipe 4 is applied on cooling cycle system 200, the efficiency of cooling cycle system 200 can be promoted.
Thus, according to the compressor assembly 100 of the embodiment of the present invention, by arranging loop circuit heat pipe 4, the temperature of compressor such as rotary compressor effectively can be reduced, and without the need to increasing outside power consumption.When compressor assembly 100 is applied to cooling cycle system 200, the efficiency of whole cooling cycle system 200 can be improved.
Below with reference to Fig. 1-Fig. 3, the compressor assembly 100 according to the present invention's specific embodiment is described.
As depicted in figs. 1 and 2, compressor assembly 100 comprises compressor and loop circuit heat pipe 4.Compressor such as rotary compressor comprises housing 11, motor 21 and compressing mechanism, and motor 21 and compressing mechanism are all located in housing 11, and motor 21 is connected with compressing mechanism.Specifically, compressing mechanism comprises main bearing 31, cylinder 32, supplementary bearing 33, piston 35 and bent axle 34, main bearing 31 is located at the upper end of cylinder 32 and supplementary bearing 33 is located at the lower end of cylinder 32, the upper end of bent axle 34 is connected with the rotor of motor 21, and lower end is through main bearing 31, cylinder 32 and supplementary bearing 33, it is outer and be positioned at cylinder 32 that piston 35 is set in bent axle 34, and cylinder 32 has intakeport 321 and relief opening 322.
Wherein, compressing mechanism is formed with receiving cavity, receiving cavity has entrance 3251 and outlet 3252, and wherein vaporizer 41 is located in receiving cavity.Such as, when cylinder assembly comprises a cylinder 32, cylinder 32 is formed with receiving groove 325, between at least one and receiving groove 325 in main bearing 31 and supplementary bearing 33, limits receiving cavity.When cylinder assembly comprises multiple cylinder 32, dividing plate is provided with between adjacent two cylinders 32, at least one in multiple cylinder 32 is formed with receiving groove 325, limit receiving cavity between one of them dividing plate adjacent with cylinder 32 in main bearing 31 and supplementary bearing 33 and receiving groove 325, or adjacent with cylinder 32 two limit receiving cavity between dividing plate and receiving groove 325.Further, at least part of inwall of receiving cavity is formed with at least one circulation groove 326.
For example, referring to Fig. 1 and Fig. 2, receiving groove 325 runs through upper-end surface and the lower end surface of cylinder 32, now jointly limits above-mentioned receiving cavity between the lower surface of receiving groove 325, main bearing 31 and the upper surface of supplementary bearing 33.Thus, make that the processing of receiving cavity is simple and cost is low.Entrance 3251 is connected with liquid flow path, and outlet 3252 is connected with gas flow path.
As shown in Figure 3, the inwall of receiving cavity is all formed with circulation groove 326, the shape of cross section of each circulation groove 326 is rectangle, and now the cross section of circulation groove 326 is made up of the straightway that three sections are connected successively.Certainly, the cross section of circulation groove 326 can also be made up of curved section or curved section and straightway are formed (scheming not shown) jointly.Thus, by arranging circulation groove 326, the gaseous working medium evaporated after heat exchange can flow to outlet 3252 by circulation groove 326.Wherein, the size of circulation groove 326 can much smaller than the size of receiving cavity (such as, height and width), with make from entrance 3251 enter into working medium in receiving cavity can more fully with compressing mechanism heat exchange, thus there is better cooling effect.
Alternatively, vaporizer 41 comprises liquid-sucking core, and liquid-sucking core is preferably the liquid-sucking core of porous medium, and liquid-sucking core is located in receiving cavity.Now receiving cavity is equivalent to the inner space of the evaporator shell 411 of loop circuit heat pipe 4, and circulation groove 326 is equivalent to the gas conduit 4111 be formed on the inwall of evaporator shell 411.
Below with reference to Fig. 6 a-Figure 10 c, the concrete formation according to the receiving cavity of the multiple concrete example of the present invention is described.
As shown in Fig. 6 a-Fig. 6 c, in this concrete example, receiving groove 325 runs through upper-end surface and the lower end surface of cylinder 32, and receiving groove 325 extends along the circumference of cylinder 32, specifically, such as, receiving groove 325 is formed as circular substantially, one end of receiving groove 325 (such as, left end in Fig. 6 a) intakeport 321 can be close to arrange, and the other end (such as, right-hand member in Fig. 6 a) adjacent row gas port 322 arranges, the periphery wall of cylinder 32 is all run through to be formed entrance 3251 and outlet 3252 respectively in the above-mentioned two ends of receiving groove 325, now receiving cavity can by receiving groove 325, limit between the lower surface of main bearing 31 and the upper surface of supplementary bearing 33.
Preferably, the contiguous intakeport 321 of entrance 3251 is arranged, and exports 3252 adjacent row gas ports 322 and arranges.Thus, because the suction side refrigerant temperature of cylinder 32 is relatively low, and the temperature of the working medium entered from entrance 3251 is also lower, effectively can reduce invalid suction superheat like this, increase gettering quantity, and, in the process that refrigerant moves to exhaust side, temperature raises gradually, and working medium can carry out heat exchange to reduce the temperature of refrigerant with refrigerant in the process flowed to outlet 3252, thus the delivery temperature of compressor such as rotary compressor can be reduced, and without the need to increasing outside power consumption, thus the efficiency of whole cooling cycle system 200 can be increased substantially.
The inwall of receiving groove 325 is all formed with circulation groove 326.Specifically, as fig. 6 c, the madial wall of receiving groove 325 and outer side wall are all formed with multiple circulation groove 326, multiple circulation groove 326 is spaced apart from each other setting in the short transverse of cylinder 32, and each circulation groove 326 can extend along the inwall of receiving cavity from entrance 3251 towards the direction of outlet 3252, with better by the gaseous working medium exit 3252 after heat exchange.
Alternatively, the height of each circulation groove 326 is h, and width is l, and wherein, h, l meet respectively:

Wherein, q is the heat that loop circuit heat pipe 4 is taken away in the cylinder 32 of compressor such as rotary compressor.
Then formula (4)-Shi (5) is known:
Q-Q’＝(h2-h1)-(h2’-h1)-q＝h2-h2’-q(7)
Therefore, the vaporizer 41 of hypothesis loop heat pipe 4 is arranged on relief opening 322 place of compressor, so according to law of conservation of energy, then has:
