Atomization unit body and engine overflow type icing test equipment with same

The invention belongs to the field of aero-engine tests, and particularly relates to an atomization unit body and engine overflow type icing test equipment with the same. The atomization unit body comprises a shell, spray rods and nozzles, wherein the shell is in a cylindrical shape; the multiple spraying rods are arranged in the shell in parallel, and the multiple spraying rods are arranged in the shell in a parallel mode; and the multiple nozzles are installed on the spraying rods respectively, the multiple nozzles are arranged in a regular hexagon shape, and the nozzles on the adjacent spraying rods are arranged in a staggered mode. The performance index of icing atomization equipment can be improved, the test capacity range of the icing atomization equipment can be expanded, the icing atomization equipment can meet the requirements of overflow type icing tests of engines of different models, meanwhile, for small-air-flow engine icing tests, the working region range of the atomization unit bodies is effect
