The invention provides an automobile air conditioner outdoor heat exchanger, a control method and a vehicle. The outdoor heat exchanger comprises a first collecting pipe, a second collecting pipe and a plurality of flat pipe sets. Wherein the first collecting pipe comprises a first sub collecting pipe and a second sub collecting pipe which are arranged side by side, and the second collecting pipe comprises a third sub collecting pipe and a fourth sub collecting pipe which are arranged side by side; the air inlet end of the second sub collecting pipe is used for being connected with the output end of a compressor; each flat pipe group comprises an inner flat pipe and an outer flat pipe arranged outside the inner flat pipe in a sleeving manner, the plurality of inner flat pipes are communicated with the first sub-collecting pipe and the fourth sub-collecting pipe to form a zigzag first flow channel, and the plurality of outer flat pipes are communicated with the second sub-collecting pipe and the third sub-collecting pipe to form a zigzag second flow channel; and a gas supplementing pipeline is arranged between the second sub collecting pipe and the first sub collecting pipe. In the refrigeration mode, the gas supplementing pipeline is opened to enable the first refrigerant to enter the first flow channel so as to adjust the supercooling degree of the first refrigerant circulating in the outdoor heat exchanger.
本发明提供了一种汽车空调室外换热器、控制方法及车辆,该室外换热器包括:第一集流管、第二集流管和多个扁管组;其中,第一集流管包括并排设置的第一子集流管和第二子集流管,第二集流管包括并排设置的第三子集流管和第四子集流管;第二子集流管的进气端用于与压缩机的输出端连接;每个扁管组包括内扁管和套设在内扁管外的外扁管,多个内扁管连通第一子集流管和第四子集流管构成曲折型的第一流道,多个外扁管连通第二子集流管和第三子集流管构成曲折型的第二流道;其中,第二子集流管与第一子集流管之间设置气体补充管路。在制冷模式下,本发明通过开通气体补充管路以使第一制冷剂进入第一流道,以调节室外换热器中流通的第一制冷剂的过冷度。
