Embodiment 1

[0084] refer to figure 1 , the liquid separator 100 includes an inflow pipe 150 , a separation element 110 , a gas phase pipe 120 , a liquid phase pipe 130 and a mixing element 140 . Wherein, the separator 110 is tubular, one end of the inflow pipe 150 is connected to the middle of the separator 110, the gas phase pipe 120 is connected to and communicates with the separator 110 through the first elbow joint 115 at the top of the separator 110, and the liquid phase pipe 130 passes through the The second elbow joint 116 at the bottom of the separator 110 connects and communicates with the separator 110 , and the liquid phase pipe 130 and the gas phase pipe 120 extend vertically and are arranged in parallel and at intervals. The gas phase tube 120 is provided with a plurality of first branch holes 121 arranged at intervals up and down, and the liquid phase pipe 130 is provided with a plurality of second branch holes 131 arranged at intervals up and down. The branch holes 131 are...

Embodiment 2

[0094] The structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same parts use the same reference numerals. The tangential direction of the member 110 on the cylinder wall. However, in the second embodiment, the inflow pipe 150 is introduced into the separator 110 obliquely downward from the upper part, so that the refrigerant flows into the gas-liquid separation chamber 111 obliquely downward to realize the preliminary separation of gas and liquid, and the inside of the separator 110 can be separated visually. Adding or not adding auxiliary separation device (demister) can also maximize the heat exchange capacity.

Abstract

The invention discloses a liquid separator, a heat exchanger with the liquid separator and an air conditioner, and the liquid separator comprises a separation part, a liquid-liquid separation part and a liquid-liquid separation part, each mixing piece comprises a gas phase branch pipe section, a liquid phase branch pipe section and a mixing branch pipe section, one end of each gas phase branch pipe section and one end of each liquid phase branch pipe section are connected to the inlet end of the corresponding mixing branch pipe section in parallel, the other end of each gas phase branch pipe section is connected with the gas phase pipe, and the other end of each liquid phase branch pipe section is connected with the corresponding liquid phase pipe; the multiple gas phase branch pipe sections of the multiple mixing pieces are arranged along the gas phase pipe at intervals, the multiple liquid phase branch pipe sections of the multiple mixing pieces are arranged along the liquid phase pipe at intervals, and the outlet ends of the mixing branch pipe sections are used for being connected with heat exchange branches of the heat exchanger. According to the liquid separator, the refrigerant flow of each branch can be matched with the heat exchange capacity of the corresponding heat exchange branch in the heat exchanger, and therefore the heat exchange performance of the heat exchanger can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a liquid separator, a heat exchanger and an air conditioner with the liquid separator. Background technique [0002] In air-conditioning and refrigeration equipment, the distributor is used to divide the refrigerant entering the evaporator to ensure that the refrigerant flow rate in each flow path, especially the liquid flow rate, matches the heat transfer capacity, thereby improving the heat transfer performance of the entire heat exchanger. In the related technology, due to the uneven wind speed facing the indoor / outdoor heat exchangers, it is difficult to adjust the flow distribution and does not match the air volume, so that the heat transfer performance of the heat exchangers is greatly attenuated. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present inv...
