The invention provides a wind velocity field test device and a method for an outdoor unit of an air conditioner. The wind velocity field test device for the outdoor unit of the air conditioner comprises a wind velocity measurement device and a test tooling; and the test tooling comprises a fixed plate and a plurality of fins fixedly arranged on the fixed plate, and a plurality of through holes for inserting wind measurement probes of the wind velocity measurement device are further arranged on the fixed plate in addition to the positions of the fins. The invention can accurately and conveniently obtain wind velocity values corresponding to various positions in the outdoor unit by fixing the fixed plate in the outdoor unit to be measured and then inserting the wind measurement probes of the wind velocity measurement device into the through holes, thereby obtaining a vector map of a wind velocity field which corresponds to the outdoor unit to be measured more accurately according to themeasured wind velocity values which correspond to the various through holes, and improving the accuracy of calculation of the vector map of the wind velocity field of the outdoor unit.
