Gas collecting tank device with multiple evaporators connected in parallel

The invention discloses a gas collecting tank device with multiple evaporators connected in parallel, and relates to the field of refrigeration air conditioners. The device comprises a gas return header tube and a plurality of sub-evaporators connected in parallel, and is structurally characterized by further comprising a gas collecting tank, wherein gas collecting pipes of the sub-evaporators are connected to refrigerant inlet tubes at the upper end of the gas collecting tank in a one-to-one correspondence mode, and a refrigerating machine outlet tube at the lower end of the gas collecting tank communicates with the gas return header tube. Compared with the prior art, the gas collecting pipes of all the evaporators are evenly mounted on the air return header tube, so that the pressure drop of all the evaporators is consistent, and even liquid distribution of the evaporators is facilitated; and meanwhile, the gas collecting tubes are convenient to mount. 一种多蒸发器并联的集气罐装置。涉及制冷空调领域。本发明装置包括回气总管和多个并联的子蒸发器。其结构特点是，它还
