Gas-liquid uniform distribution device

The utility model discloses a gas-liquid uniform distribution device. The device comprises a gas-liquid injection sealing strip disposed in a plate-fin heat exchanger core body. The plate-fin heat exchanger core body is provided with a gas inlet end socket and a liquid inlet end socket. Moreover, the gas inlet end socket is disposed above the liquid inlet end socket. The gas-liquid injection sealing strip is provided with a liquid groove and a gas groove. The liquid inlet end socket is communicated with the liquid groove, and the gas inlet end socket is communicated with the gas groove. The device does not increase the number of apparatuses, so the device is simple and reasonable in system structure, and is low in construction cost. The device employs a mode that liquid enters into a flow channel from two sides of the sealing strip and gas enters into the flow channel from the center. A wall surface of a partitioning plate in the flow channel is provided with a liquid film, thereby avoiding a phenomenon of heat transfer deterioration caused by the local complete vaporization happening at the partitioning plate nearby the sealing strip.
