The invention discloses an air conditioner outdoor unit, a circulating system and a control method, relates to the technical field of air conditioners, and aims to solve the problem that a plurality of compressor driving modules are unbalanced in temperature and are prone to condensation. The air conditioner outdoor unit comprises a plurality of compressors, driving modules and heat exchange blocks, wherein the compressors are arranged in the outdoor unit, each compressor is correspondingly provided with one driving module, the driving modules are used for driving the corresponding compressors to operate, and each heat exchange block comprises a first heat exchange part and a second heat exchange part which are connected with the corresponding driving module and are integrally formed. A metal pipe is inserted into the heat exchange blocks and used for circulating a refrigerant, and the heat exchange blocks are used for carrying out heat exchange between the metal pipe and the driving modules so as to reduce t
