Rectifying tube and gas-liquid distribution device

The invention belongs to the field of refrigeration technology and equipment, and relates to a rectifying tube and a gas-liquid distribution device. A rectifying tube comprises an inner cylinder and an outer cylinder, the inner cylinder is sleeved with the outer cylinder, a center columnar flow channel is formed in the space in the outer cylinder, and an annular flow channel is formed in the space between the outer cylinder and the inner cylinder. One end of the annular flow channel is closed and is a closed end of the rectifying tube; the other end of the annular flow channel is communicated with the central columnar flow channel and is a rectifying tube communication end; and a plurality of distribution holes are formed in the wall surface of the outer cylinder. According to the rectifying tube provided by the invention, gas-liquid two-phase fluid can be uniformly distributed and is not limited by the number of heat exchange branches. 本发明属于制冷技术与装备领域，涉及一种整流管、气液分配装置。一种整流管，包括内圆筒和外圆筒，外圆筒套设在内圆筒上，外圆筒内的空间形成中心柱状流道，
