and the heat exchanger sections of short straight plate section, almost account for whole " L " type heat exchanger half heat exchange area, but it is positioned at outside the circumference at impeller of blower Ye Jing place, the turnover air quantity obtained, turnover wind speed is only small, the even short straight plate section end of " L " type heat exchanger, almost without air inlet/outlet, constrain the heat exchanger effectiveness of whole heat exchanger, therefore the structural design of blower motor and heat exchanger how is optimized, make each section of " L " type heat exchanger can obtain bigger air inlet/outlet, so that heat exchanger obtains heat exchange the most fully and fails, to obtain higher heat exchanger effectiveness and also just become people to thirst for solution always, the technical barrier succeeded all the time,And the space of median septum opposite side generally arranges compressor and frequency conversion electrical control box, the present invention is referred to as compressor and frequency conversion electrical control box space, space is relatively small, compressor and frequency conversion electrical control box space four periderm median septum enclose with outdoor set cabinet, with lie substantially in closed state outside outdoor set cabinet, no matter freeze or heat, during operation of air conditioner, compressor and frequency conversion electrical control box will produce amount of heat, especially the heat that frequency-variable module produces is bigger, as dispelled the heat not in time, frequency conversion electrical control module cannot even be burnt by normal operation, compressor temperature is too high also can affect compressor performance and service life, over-temperature protection device will be triggered when frequency-variable module and compressor temperature are too high, force frequency-variable module frequency reducing work even out of service, air-conditioning efficiency declines, compressor also can shut down, therefore frequency-variable module and compressor radiating and cooling must be given, usual frequency-variable module adopts these three radiating and cooling mode: 1, the frequency conversion electrical control box arrange frequency-variable module arranges air-cooled radiator heat radiation, radiator againsts median septum design in blower fan

radiator heat exchange, 2, frequency conversion electrical control box arranges special radiator fan and heat dissipation wind channel is frequency conversion electrical control box radiating and cooling, 3, frequency conversion electrical control box radiating and cooling is cooled down by arranging coolant loop, 1st kind of radiating mode, it is in open state completely outside blower fan and heat exchanger sections and off-premises station, needs for sufficient heat exchange, heat exchanger air intake surface needs are designed to bigger, so the negative-pressure inlet region formed during blower fan operating is very big, for whole heat exchanger air intake surface, and radiator negative-pressure inlet face only accounts for wherein small part, it is generally about 1%, and it is positioned at the marginal area that fan blade inlet side air intake flow is less, thus negative pressure is only small, the air quantity flowing through radiator is inevitable only small, wind-cooling heat dissipating efficiency is very low, especially when summer environment temperature is higher, frequency-variable module often dispels the heat bad, overheat protector is easily triggered and out of service during long-time hot operation, frequency-variable module runs for a long time under such conditions, service life can shorten, even can burn out, 2nd kind of radiating mode, increase fan and power consumption cost, and be limited by the limitation of compressor and frequency conversion electrical control box space and be set to too small, heat radiation air quantity is also less, radiating effect is still bad, 3rd kind of radiating mode, coolant cooling frequency conversion electrical control box, temperature difference when refrigerant temperature and frequency-variable module work is very big, on frequency-variable module surface and automatically controlled circuit board, very easily form condensation, thus bringing the hidden danger of frequency-variable module wiring board short circuit, and compressor is generally natural heat dissipation and arranges heat abstractor heat radiation, the effect of radiating and cooling is also unsatisfactory, the shutdown that high temperature causes happens occasionally. therefore, namely design one does not increase production cost on now air-conditioned basis, during heat radiation work, not power consumption increases expense again, and frequency-variable module is not had the hidden danger that short circuit burns out, the radiating mode that radiating effect is multiplied, also just becomes people and thirsts for solving always but fail the technical barrier succeeded all the time.

Blower fan in the present invention is axial flow blower, the air-conditioner outdoor unit of the present invention refers in particular to employing axial flow blower air inlet/outlet, blower fan air intake is through the heat exchanger heat exchange of " L " type, again through the off-premises station of air-out before axial flow blower, heat exchanger in air-conditioner outdoor unit of the present invention refers in particular to " L " type heat exchanger, a kind of " U " type or be called the heat exchanger of " n " type in prior art, it being by L on the basis of " L " type heat exchanger " the straight plate section of the length of type heat exchanger is again bent at circular arc after lengthening, make heat exchanger entirety in " U " type or the heat exchanger of " n " type, substantially comprise the feature of " L " type heat exchanger.
The characteristic of axial flow blower air inlet/outlet is: fan blade promotes the air direction flowing to parallel with motor rotation axis, intake, air intake wind speed is strengthened gradually strengthening by fan blade center to fan blade leaf footpath circumference from zero, until fan blade leaf footpath circumference reaches maximum, cross fan blade leaf footpath circumference, intake, it is zero that air intake wind speed is sharply decreased until, therefore, should as much as possible the heat exchanger of bigger heat exchange area be arranged in the main air draught region in the rotation round of fan blade leaf footpath, to make full use of blower fan air intake to heat exchanger heat exchange. fan design in existing air-conditioner outdoor unit is fan rotation shaft axial line and " L " type heat exchanger length straight plate perpendicular structure of section centrage, namely the structure that impeller of blower leaf footpath is parallel with " L " type heat exchanger length straight plate section, air intake is directly facing to " L " type straight plate section of heat exchanger length, the straight plate section of " L " type heat exchanger length faces the air inlet/outlet air quantity of the heat exchanger sections in fan blade rotation round region, air inlet/outlet wind speed is maximum the fastest, thus the heat exchanger effectiveness of " L " type heat exchanger length straight plate section is the highest, but almost account for the arc section of " L " type heat exchanger half and the heat exchanger sections of short straight plate section, it is positioned at outside impeller of blower rotation round region, turnover air quantity, turnover wind speed is less slower, the even short straight plate section end of " L " type heat exchanger, almost without air inlet/outlet, seriously constrain the arc section accounting for " L " type heat exchanger half and the heat exchange performance of short straight plate section heat exchanger. blower motor is rotated axle axial line and the straight plate section centrage of " L " type heat exchanger length angle be designed as the structure less than or equal to 85 degree, impeller of blower leaf footpath and " L " type heat exchanger length straight plate section are certain angle, the impeller of blower rotation round region making intake maximum deflects to " L " type heat exchanger arc section, arc section and the short straight plate section of " L " type heat exchanger are achieved with bigger intake, " L " type heat exchanger section faced toward due to impeller of blower rotation round region contains heat exchanger arc section, and circular arc arc length is necessarily longer than circular arc chord length, so " L " type heat exchanger section area that same impeller of blower rotation round region faces toward just necessarily faces the heat exchange area in impeller of blower rotation round region more than the straight plate section of above-mentioned " L " type heat exchanger length, by maximum blower fan air intake facing to bigger " L " type heat exchanger heat exchange area region, " L " type heat exchanger just obtains heat exchange more fully, also just improve the heat exchanger effectiveness of " L " type heat exchanger, " L " type heat exchanger obtains heat exchange more fully and also just solves people and thirst for solving always but fail the technical barrier succeeded all the time obtaining higher heat exchanger effectiveness.
Blower motor rotates the angle of axle axial line and " L " type heat exchanger length straight plate section centrage and refers to the minimum angle of blower motor rotation axle axial line and " L " type heat exchanger length straight plate section centrage during impeller of blower deflection " L " type heat exchanger arc section, and heat exchanger length straight plate section centrage refers to the centrage of the straight plate section thickness of " L " type heat exchanger length. blower motor rotates axle axial line deflection " L " type heat exchanger arc section, impeller of blower will deviate " L " type straight plate section of heat exchanger length to some extent, the air inlet/outlet of the straight plate section end of " L " type heat exchanger length can weaken to some extent, owing to arc section and the short straight plate section of " L " type heat exchanger obtain bigger intake and be able to sufficient heat exchange, improve the heat exchanger effectiveness of " L " type heat exchanger, now, can suitably shorten " L " type straight plate section of heat exchanger length, remove the part of " L " type heat exchanger length straight plate section end heat exchanger effectiveness difference, total heat exchanger effectiveness of " L " type heat exchanger, still above the heat exchanger effectiveness that the fan design in existing air-conditioner outdoor unit is fan rotation shaft axial line and " L " type heat exchanger of " L " type heat exchanger length straight plate perpendicular structure of section, and shorten " L " type straight plate section of heat exchanger length, the production cost of " L " type heat exchanger will decline, in addition the feature that following median septum can be arranged to blower fan with heat exchanger space displacement, air-conditioner outdoor unit profile length on " L " type heat exchanger length straight plate section direction also can shorten, these all can reduce the production cost of off-premises station.
Blower motor rotate axle axial line and the straight plate section centrage of " L " type heat exchanger length angle less than or equal to 85 degree, the impeller of blower rotation round region that intake just can be made maximum deflects to " L " type heat exchanger arc section, but heat exchanger arc section should not be excessively partial in impeller of blower rotation round region, otherwise excessive will affect the heat exchanger effectiveness of " L " type straight plate section of heat exchanger length, so, rotate the axle axial line angle with " L " type heat exchanger length straight plate section centrage with blower motor and arrive less than or equal to 80 degree as best be more than or equal to 30 degree.
During air-conditioning work, off-premises station fan starting, suck air and discharged off-premises station by blower fan after the heat exchanger heat exchange of " L " type, off-premises station air intake surface is much larger than outlet air surface, outlet air surface significantly shrinks, the air blast that blower fan outlet air surface is discharged is strengthened, thus portion of air therein will flow to the air inducing air inlet of air duct that fan outlet is arranged, entrance compressor and frequency conversion electrical control box space is collected through air inducing air channel, flowing through compressor, during frequency conversion electrical control box, absorb compressor case, heat heating on frequency conversion electrical control box becomes hot-air, discharged by the air outlet in outdoor set cabinet, reach to the goal of the invention of the cooling electronic component coolings such as the frequency-variable module in compressor and frequency conversion electrical control box.
During air conditioner refrigerating, air outside off-premises station absorbs heat after the heat exchanger heat exchange of " L " type and becomes hot-air, off-premises station is discharged by blower fan, although the air temperature discharging off-premises station improves into hot-air, but the temperature of hot-air is consistently lower than frequency conversion electrical control box surface temperature more than 20 DEG C, more below compressor case surface temperature, the temperature of hot-air that I guess air conditioning condition allow the highest use ambient temperature 53 DEG C time temperature also only at about 62 DEG C, and compressor case surface temperature now is up to about 100 DEG C, the temperature of the frequency-variable module in frequency conversion electrical control box makes the temperature of frequency conversion electrical control box reach about 80 DEG C, therefore, hot air temperature is still far below the temperature of compressor case and frequency conversion electrical control box surface, the air inducing air inlet of air duct that a part of hot-air discharged by blower fan is arranged by fan outlet, entrance compressor and frequency conversion electrical control box space is collected through air inducing air channel, through compressor, during frequency conversion electrical control box, still can absorb compressor case, heat on frequency conversion electrical control box becomes hotter hot-air, discharged by the air outlet in outdoor set cabinet, it is reached for compressor and the purpose of frequency conversion electrical control box radiating and cooling, compressor and frequency conversion electrical control box obtain radiating and cooling, frequency conversion electrical control components and parts in compressor and frequency conversion electrical control box just can be under a suitable temperature case all the time and run, improve compressor and frequency conversion electrical control components and parts performance and used life, ensure that air-conditioning high energy efficiency operating mode.
During air-conditioning heating, the heat release after the heat exchanger heat exchange of " L " type of air outside off-premises station becomes cold air, off-premises station is discharged by blower fan, what discharged by blower fan is cold air, the air inducing air inlet of air duct that a part of cold air therein is arranged by fan outlet, collect entrance compressor through air inducing air channel and become electric-controlled box space, through compressor, during frequency conversion electrical control box, absorb compressor case, the ability of the heat on frequency conversion electrical control box is just higher, frequency conversion electrical control box, and compressor case radiating and cooling effect is just better.
If that air-conditioning adopts is the R290 of day by day popularization and application, the combustible refrigerant systems such as R32, after the refrigerant line in compressor of outdoor unit and frequency conversion electrical control box space occurs the tiny leakage at the various places of being tightly connected leaking or being difficult to avoid that to be accumulated to finite concentration, combustible refrigerant enters frequency conversion electrical control box, it is possible to occur the electronic devices and components sparking in frequency conversion electrical control box to ignite the danger of blast, the air-conditioning of the present invention, discharge the air inducing air inlet of air duct that the portion of air of blower fan is arranged by fan outlet, collect entrance compressor and frequency conversion electrical control box space, through compressor, off-premises station is discharged after frequency conversion electrical control box, if there is cold-producing medium leakage, the cold-producing medium of leakage also will be discharged off-premises station at any time, leakage is occurred to be likely to the hidden danger that set off an explosion thus eliminating combustible refrigerant system air conditioner off-premises station.
The technical characteristic of " blower motor rotates the axle axial line angle with the straight plate section centrage of " L " type heat exchanger length less than or equal to 85 degree " is changed to the technical characteristic of " blower motor rotates the axial line of axle and the angle of rectangle bottom surface two minor face midpoint line less than or equal to 85 degree ", it it is another technical scheme, so can the present invention be expanded is applied on the air-conditioner outdoor unit of heat exchanger of other structures, such as parallel flow heat exchanger etc., reach equally when not increasing energy consumption to the frequency conversion electrical control components and parts in frequency conversion electrical control box and compressor radiating and cooling, improve the performance and used life of compressor and frequency conversion electrical control components and parts, compressor and frequency conversion mould is made to be in good working order soon all the time, guarantee the goal of the invention that air-conditioning high energy efficiency works.
The frequency conversion electrical control box of the present invention is entirely located in compressor and frequency conversion electrical control box space, radiator on frequency conversion electrical control box also is located in compressor and frequency conversion electrical control box space, radiator on frequency conversion electrical control box is socketed wind-collecting cover, just can will collect the blower fan air-out entering compressor and frequency conversion electrical control box space through air inducing air channel, it is concentrated through the radiator heat exchange on frequency conversion electrical control box, reach the radiating effect of the best, radiator offers some air vents on the wind-collecting cover of socket, the blower fan air-out entering compressor and frequency conversion electrical control box space is collected through air inducing air channel, will partly distribute wind-collecting cover, through compressor and take away the heat on compressor case, after compressor radiating and cooling, discharged by the air outlet in outdoor set cabinet.
Blower motor rotates the angle of axle axial line and the straight plate section centrage of " L " type heat exchanger length technical characteristic less than or equal to 85 degree and blower motor rotates the angle of the axial line of axle and the rectangle bottom surface two minor face midpoint line technical characteristic less than or equal to 85 degree, make impeller of blower deviation median septum, space between the impeller of blower and the median septum that have moved greatly, the whole frequency conversion electrical control box including radiator plus the present invention is provided entirely in compressor and frequency conversion electrical control box space, thus arranging of median septum can be moved a certain distance to blower fan and heat exchanger space, moveable distance, apparent wind machine blade deviation angle size and determine, generally removable about 60mm, compressor and frequency conversion electrical control box space are significantly expanded, there is this well-to-do expanding space, the frequency conversion electrical control box that just can implement the present invention better is entirely located in compressor and frequency conversion electrical control box space, radiator on frequency conversion electrical control box also is located at compressor and frequency conversion electrical control box space, radiator on frequency conversion electrical control box is socketed the technical characteristic of wind-collecting cover, just can be properly arrived at the object of the invention, this is that existing air-conditioner outdoor unit limits to narrow compressor and frequency conversion electrical control box space can not be accomplished.
The air inducing air channel of the present invention communicates through median septum with compressor and frequency conversion electrical control box space, it is also designed to walk around median septum communicate with compressor and frequency conversion electrical control box space, the structure setting perpendicular with " L " type heat exchanger length straight plate section centrage of axle axial line is rotated if blower fan is still existing blower motor, namely blower motor rotates the perpendicular structure setting with the line at rectangle bottom surface two minor face midpoint of the axial line of axle, the air-out direction of blower fan and compressor and frequency conversion electrical control box space be from, want to introduce air-out to compressor and frequency conversion electrical control box space by air inducing air channel, air inducing air channel is necessary for being arranged to the air channel of certain bending, air-out just can curve and return in compressor and frequency conversion electrical control box space, air-out is bending flowing in air inducing air channel, noise can be increased, reduce blast, air inducing air channel is set to bending air duct, production cost can increase, off-premises station profile can increase, bring off-premises station production cost, packaging material, cost of transportation improves accordingly, the setting of the present invention " blower motor rotates the axle axial line angle with the straight plate section centrage of " L " type heat exchanger length less than or equal to 85 degree ", make blower fan air-out to compressor and frequency conversion electrical control box spatial deflection, just air inducing air channel can be arranged within the scope of existing outdoor set cabinet profile, as air inducing air channel is set to straight channel, thus solving air-out bending flowing in air inducing air channel, noise can be increased, reduce blast, air inducing air channel production cost increases, off-premises station profile increases, bring off-premises station production cost, packaging material, the problem that cost of transportation improves accordingly. air inducing air channel has air inlet and air outlet, air inducing air channel communicates through median septum with compressor and frequency conversion electrical control box space, namely air inducing duct outlet communicates with compressor and frequency conversion electrical control box space, at fan outlet, air inducing air inlet of air duct is set, referring to that air inducing air inlet of air duct is facing to fan outlet, fan outlet refers to that the cross section of kuppe during impeller of blower kuppe is discharged in blower fan air-out. blower fan exhaust air flue and the air inducing air channel shape of cross section communicated with compressor and frequency conversion electrical control box space through median septum may be designed as other shapes such as circle, square, rectangle, as long as meeting air inducing smoothness, but are preferred with rectangle.
It is perspective plane in the plane formed with fan outlet, when the plane that the plane that air inducing air inlet of air duct is formed and fan outlet are formed projection on this perspective plane forms faying surface, the part perspective plane that faying surface can be in two projections is overlapping, it is also possible to be that the perspective plane that air inducing air inlet of air duct is formed has been forgiven on the plane that formed of fan outlet perspective plane on this perspective plane.There is no faying surface, the air quantity that air inducing air inlet of air duct introduces fan outlet is very little, the air quantity entering compressor and frequency conversion electrical control box space is very little, even without introducing air quantity, the goal of the invention of the present invention cannot be reached, only form faying surface, air inducing air inlet of air duct could introduce the air quantity of fan outlet, could start to realize the goal of the invention of the present invention, if the air quantity that air inducing air inlet of air duct introduces fan outlet is too small, after entering compressor and frequency conversion electrical control box space, it is impossible to and compressor and frequency conversion electrical control box sufficient heat exchange, reach the present invention invention effect just poor, only when more than the 20% of the plane that above-mentioned faying surface area is formed more than fan outlet projected area on this perspective plane, air inducing air inlet of air duct could introduce the air-out volume that fan outlet is bigger, the faying surface formed is more big, the blower fan air output that air inducing air inlet of air duct is introduced is more big, the goal of the invention and the invention effect that realize the present invention are also more good, but faying surface need not be as big as to the 100% of plane that fan outlet the formed projected area on this perspective plane, now, the air-out of fan outlet will all be introduced by air inducing air inlet of air duct, it is do not need so big air quantity with the air of compressor and frequency conversion electrical control box heat exchange, also the smooth and easy air-out of off-premises station can be produced impact and then affect the smooth and easy air intake of off-premises station simultaneously, also air inducing air channel noise can be increased, the present invention recommends the 60% of plane that faying surface formed less than the fan outlet projected area on this perspective plane, just because of this design of the present invention, take full advantage of the feature that fan outlet air-out blast is stronger, the air output making the fan outlet that air inducing air inlet of air duct introduces is bigger, it is sufficient for as frequency conversion electrical control box and compressor radiating and cooling.
Radiator on existing air-conditioning frequency conversion electrical control box is fitted tightly on frequency conversion electrical control box by thermal grease, in frequency conversion electrical control box, heat of high temperature during frequency-variable module work first passes through frequency conversion electrical control box, then pass through thermal grease and just can be delivered to radiator heat-dissipation, can decline through the heat radiation heat transference efficiency of repeatedly indirect transfer, after air-conditioning uses, thermal grease can shrink, connection between radiator and frequency conversion electrical control box can loosen, certain loosening gap can be produced, heat transference efficiency can decline bigger, the radiating effect of frequency conversion electrical control box can become poor, radiator on usual frequency conversion electrical control box is arranged in the frequency conversion electrical control box cassette bottom that frequency conversion electrical control box frequency-variable module is corresponding, it is an entirety by frequency conversion electrical control box and fansink designs, i.e. frequency conversion electrical control box and the disposable production molding of radiator, then cover frequency conversion electrical control box lid and form frequency conversion electrical control box, heat of high temperature when just can be worked by frequency-variable module repeatedly indirect transfer is changed into radiator and disposable is directly delivered to radiator, substantially increase heat conduction efficiency, thus further improve the effect of frequency conversion electrical control box radiating and cooling. frequency conversion electrical control box and the disposable production of radiator are molded into and can adopt molding, the production technologies such as cold-heading pressure, frequency conversion electrical control box and radiator are that an entirety also includes frequency conversion electrical control box lid and the disposable generation of radiator, then frequency conversion electrical control box box body is covered, so, radiator is located on the lid that in frequency conversion electrical control box, frequency-variable module is corresponding.
Owing to the frequency conversion electrical control box of the present invention is provided entirely in compressor and the frequency conversion electrical control box space of median septum side, the upper and lower space of frequency conversion electrical control box is more spacious, make to adopt what frequency conversion electrical control box lid and cassette bottom be equipped with radiator to be designed to possibility, double-radiator setting just can make full use of and enter the sufficient blower fan air-out in compressor and frequency conversion electrical control box space to frequency conversion electrical control box radiating and cooling by air inducing air channel, radiating efficiency will significantly improve, frequency conversion electrical control box lid and cassette bottom are equipped with the design of radiator, it is the one in holistic design that the connected mode of radiator and frequency conversion electrical control box can adopt above-mentioned radiator to be fitted tightly over frequency conversion electrical control box or frequency conversion electrical control box with radiator by thermal grease, also can two kinds of mixed design application.
