The technical solution of the utility model is a kind of newly-designed condenser for outdoor unit of air conditioner, by double U type pipe, intervalve 12, gather pipe 6, outlet and some elbows are formed, wherein on total inlet pipe 2, tell 3 arm 2-1,2-2,2-3 that bore is identical, gather the pipe group by three internal diameters and pipe range adjustable arm 4-1,4-2,4-3, pressure drop type current divider 5, gather pipe 6 and form.
Referring to Fig. 2, the leeward side 10, three tunnel that No. three air intake branch 2-1,2-2,2-3 all are arranged at condenser 1 goes out the windward side 11 that gas branch pipe 4-1,4-2,4-3 are arranged at condenser 1.Each diverter branch 3-1,3-2,3-3 are 7 U type pipe 9-1,9-2,9-3 form, and the U type pipe 9-4 of super cooled sect 7 windward sides is that 3 U type pipes are formed, and condenser 1 has 24 U type pipes altogether like this.The flow process of described three diverter branch 3-1,3-2,3-3 is for falling the setting of " U " type.Wherein, the part U type pipe 9-3 among the 3rd diverter branch 3-3 is arranged on super cooled sect 7 leeward sides 10 zones.
During work, behind the U type pipe row of the cold-producing medium flow process of described diverter branch 3-1,3-2,3-3 for the leeward side 10 of all flowing through earlier, the U type pipe row of the windward side 11 of flowing through again.Then, enter three and go out gas branch pipe 4-1,4-2,4-3, and collect in the import of current divider 5 jointly,, flow out from always going out pipe 8 at last again from gathering the U type pipe 9-4 that pipe 6 enters super cooled sect 7 windward sides.
Referring to Fig. 3, as different from Example 1, the flow process of described three diverter branch 3-1,3-2,3-3 is for falling the setting of " N " type.
Embodiment 3
Referring to Fig. 4, as different from Example 1, first and second road 3-1 in the described diverter branch, 3-2 flow process are for falling the setting of " U " type, and described the 3rd diverter branch 3-3 flow process is for falling the setting of " N " type.
Implementation column 4
Referring to Fig. 5, as different from Example 1, first and third road 3-1 in the described diverter branch, 3-3 flow process are for falling the setting of " N " type, and the described second diverter branch 3-2 flow process is for falling the setting of " U " type.
Referring to Fig. 6, as different from Example 1, the first via 3-1 flow process in the described diverter branch is for falling the setting of " U " type, and second and third road 3-2 in the described diverter branch, 3-3 flow process are for falling the setting of " N " type.
Show that by experiment wherein Fig. 7 system flow chart is preferred embodiment, the Energy Efficiency Ratio height.It is made up of 24 U type pipes, and the 1 the tunnel for " U " type that falls connects, and the 2nd, the 3 tunnel for " N " type that falls connects, and gathering in 6 groups of the pipes 3, to branch out bore identical, and length of run is from the 1 the road to the 3 the tunnel for successively decreasing, and super cooled sect is connected to form by 3 U type pipes.
Referring to Fig. 7, present embodiment is the condenser of 20 U type pipes, and each diverter branch is 6 U type pipes, and super cooled sect is 2 U type pipes; Three diverter branch flow processs are down the setting of " U " type.
Referring to Fig. 8, present embodiment is the condenser of 26 U type pipes, and each diverter branch is 8 U type pipes, and super cooled sect is 2 U type pipes, and three diverter branch flow processs are down the setting of " N " type.
Referring to Fig. 9, present embodiment is the condenser of 26 U type pipes, and first and second diverter branch is that 8 U type pipes, the 3rd diverter branch are 7 U type pipes, and super cooled sect is 3 U type pipes, and three diverter branch flow processs are down the setting of " N " type.
Outdoor machine fan adopts aerofoil fan, so condenser 1 wind field wind speed claims " V " font to distribute, and referring to Figure 10, promptly wind speed is big up and down, and is middle little; The air wind-warm syndrome through condenser from windward side 11 to leeward side 10 for increasing progressively, according to the good more principle of the more little then heat exchange property of logarithm heat transfer temperature difference, therefore import is all placed leeward side 10, outlet places windward side 11, and promptly U type pipe is adverse current (cold-producing medium general flow direction and air reverses during kind of refrigeration cycle) and is provided with and is connected.After system's miniaturization, defrosting is easier to, and windward side 11 heat exchange properties are good, so super cooled sect 7 all is arranged on windward side 11, and it is cold excessively to be beneficial to cold-producing medium, increases refrigerating capacity.Branch's flow process is all by falling " U " type, referring to accompanying drawing 2, " N " type accompanying drawing 3 or of falling by " U " type of falling and " N " type of falling combination as accompanying drawing 4~6 etc., and this kind countercurrent flow layout, the flow of refrigerant resistance is little.During kind of refrigeration cycle, import is an overheated gas, exports to the subcooled liquid of certain degree of supercooling is arranged, and the density between gas and the liquid refrigerant differs greatly, therefore the flow of cold-producing medium from top to bottom each branch road successively decrease, promptly go up a branch road coil pipe flow greater than next branch road coil pipe flow.
Heat circulation time, import is the very little two-phase fluid of mass dryness fraction, exports to be overheated gas, and the flow of cold-producing medium each branch road from the bottom up successively decreases, and promptly next branch road coil pipe flow is greater than a last branch road coil pipe flow.Therefore the utility model freezes for equilibrium, heat flow process and wind field wind conditions, 3 branch out pipe and are aggregated into current divider 5, tell length of tube and internal diameter can be adjusted (adjusting refrigerant flow) for 3, when heating circulation (this moment, condenser used as evaporimeter), along with cold-producing medium evaporates in the super cooled sect of former kind of refrigeration cycle, it is big that gas-liquid two-phase cold-producing medium mass dryness fraction further becomes, therefore this current divider is a pressure drop type current divider, two-phase mix refrigerant after becoming greatly with the assurance mass dryness fraction is behind pressure drop type current divider, the mass dryness fraction of assigning to each arm is basic identical, heats circulation separatory uniformity and stability thereby improve.The U type pipe (general 2~4) that cold-producing medium after gathering enters the windward side foot is a super cooled sect, and this section cold-producing medium flow velocity is fast, helped cold, thereby the refrigerating capacity that improves.
Therefore, the actual measurement EER that the utility model condenser has solved after the outdoor condenser miniaturization is not less than former big casing off-premises station (32 U type pipework condensation devices), and specified heating capacity and low-temperature heating capacity also can satisfy instructions for use, has realized the low cost of off-premises station.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
