Description

Air conditioner outdoor unit Technical Field The utility model belongs to the technical field of air conditioning equipment, and particularly relates to an air conditioning outdoor unit. Background Because of the market cost competitiveness, compressor miniaturization is a development trend of key components such as an air conditioner outdoor unit, and in order to meet the capacity requirement of an air conditioner, it is necessary to accelerate a small-displacement compressor, so that vibration of the compressor is significantly deteriorated. The vibration of the compressor can affect the connection stability of the piping assembly connected with the compressor in addition to the noise increase of the outdoor unit of the air conditioner, increase the risks of falling off of the piping assembly and leakage of the refrigerant, and in order to reduce the influence caused by the vibration deterioration caused by the speed increase of the compressor, part of the outdoor units of the air conditioner can inhibit the vibration by fixing the piping assembly on other supporting structures or adding a balancing weight on the piping assembly, and the vibration inhibition mode can cause the problems of obvious increase of cost, exceeding stress, poor manufacturability and the like.
