Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of air-conditioner outdoor unit, with reference to Fig. 1, Fig. 2 and Fig. 5, in one embodiment, comprise liquid storage and gas-liquid separation device, described liquid storage and gas-liquid separation device comprise for preserving by the reservoir of the cold-producing medium of outdoor heat converter condensation and the gas-liquid separator for carrying out gas-liquid separation to the cold-producing medium flowing through indoor heat converter, described liquid storage and gas-liquid separation device comprise annular sidewall 100, lay respectively at first end cap 10 and second end cap 20 at described annular sidewall 100 two ends, and for by described annular sidewall 100, the cavity that first end cap 10 and the second end cap 20 surround is divided into the dividing plate 3 of the first cavity 1 and the second cavity 2, the cross section of described dividing plate 3 has at least one crest and a trough, first side of described dividing plate 3 forms described reservoir, second side of described dividing plate 3 forms described gas-liquid separator.Refrigerant compression is first become the cold-producing medium of high-temperature high-pressure state by compressor, is then the cold-producing medium of middle temperature high pressure through the effect exothermic condensation of heat exchanger of outdoor unit, then to flow in described reservoir thus to form the first cold-producing medium; First cold-producing medium flows into expansion gear after described reservoir flows out, and after expanding, pressure reduction enters heat exchanger indoor unit, then absorbs heat at heat exchanger indoor unit, and the cold-producing medium becoming low-pressure state flows into gas-liquid separator and forms second refrigerant.
By arranging the dividing plate 3 reservoir and gas-liquid separator being separated to form the first cavity 1 and the second cavity 2, make, between described first cavity 1 and the second cavity 2, there is larger heat exchange area, improve the heat exchanger effectiveness between reservoir and gas-liquid separator, thus improve stability and the Energy Efficiency Ratio of whole air-conditioning system.In addition, the integrative-structure that described reservoir, dividing plate 3 and gas-liquid separator are formed, can save the parts placement space of air-conditioner outdoor unit, makes air-conditioner outdoor unit compact conformation, easy for installation.
Further, with reference to Fig. 5, described reservoir is provided with the first feed tube 11 and drain pipe 12 on the first end cap 10 of described first cavity 1, and described first feed tube 11 and described drain pipe 12 extend in described first cavity 1 with the passage providing described first cold-producing medium to flow to and flow out; Described gas-liquid separator is provided with the second feed tube 21 and escape pipe 22 on the first end cap 10 of described second cavity 2, described second feed tube 21 extends with the passage providing second refrigerant to flow in described second cavity 2, and described escape pipe 22 is arranged in described second cavity 2 with the flow pass providing second refrigerant to become gas.
Further, with reference to Fig. 2 and Fig. 3, it is inner and L-shaped to curving that described second feed tube 21 stretches into described second cavity 2; Described escape pipe 22 to stretch to bottom described second cavity 2 and is back to the top of described second cavity 2 and takes the shape of the letter U.High-temperature high-pressure refrigerant through compressor compresses enters described first cavity 1 from described first feed tube 11, and in described reservoir, carry out heat exchange with the low-temperature refrigerant in gas-liquid separator, cooled cold-producing medium is discharged by described drain pipe 12.Low-temperature low-pressure refrigerant after expansion step-down enters described second cavity 2 by described second feed tube 21, after gas-liquid separation, wherein, gaseous refrigerant is discharged from described escape pipe 22 and is entered in compressor, and the high temperature refrigerant of the liquid refrigerant of low temperature and described reservoir carries out heat exchange.By heat exchange, make the cold-producing medium in described reservoir must be cold effect, thus can refrigerating efficiency be improved.
Further, the distance between the free end of described second feed tube 21 in described second cavity 2 and described first end cap 10 is greater than the distance between the free end of described escape pipe 22 in described second cavity 2 and described first end cap 10.Like this, the liquid refrigerant flowed into from described second feed tube 21 can be avoided to enter described escape pipe 22, and described liquid refrigerant is stayed in described gas-liquid separator, make described liquid refrigerant cannot enter compressor inside, thus prevent the damage of compressor.
Further, with reference to Fig. 4, recovery holes 220 is provided with bottom the U-shaped of described escape pipe 22, for reclaiming the lubricating oil in described gas-liquid separator.Namely reclaim the lubricating oil in cold-producing medium, described lubricating oil is back in compressor with gas.
Further, described escape pipe 22 has and is arranged in the screen pack 221 of described recovery holes 220 for filtering foreign matter.
Further, described first feed tube 11 and described drain pipe 12 stretch into the free end that the free end in described first cavity 1, described second feed tube 21 and described escape pipe 22 stretch in described second cavity 2 and are equipped with an inclined-plane.Like this, arranging of inclined-plane can increase contact area, reduces cold-producing medium when air-conditioning system is run and enters the noise produced in described reservoir and described gas-liquid separator.
Further, described dividing plate 3 is in corrugated or zigzag.Like this, the heat exchange area between described reservoir and described gas-liquid separator can be increased and improve heat exchanger effectiveness.
