An outdoor unit for an air conditioner

The present invention relates to an air conditioner.

The air conditioner is a device for keeping the air in a predetermined space in a most suitable condition according to the purpose of use and purpose. Generally, the air conditioner includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigeration cycle for compressing, condensing, expanding, and evaporating the refrigerant is driven to cool or heat the predetermined space .

The predetermined space may be variously proposed depending on the place where the air conditioner is used. For example, when the air conditioner is installed in a home or an office, the predetermined space may be an indoor space of a house or a building. On the other hand, when the air conditioner is disposed in a car, the predetermined space may be a boarding space on which a person boarded.

When the air conditioner performs the cooling operation, the outdoor heat exchanger provided in the outdoor unit functions as a condenser, and the indoor heat exchanger provided in the indoor unit functions as an evaporator. On the other hand, when the air conditioner performs the heating operation, the indoor heat exchanger functions as a condenser and the outdoor heat exchanger functions as an evaporator.

On the other hand, the air conditioner includes a refrigerant pipe for guiding the flow of the refrigerant. During the operation of the air conditioner, vibration may be generated in the refrigerant pipe.

Particularly, in a compressor installed in an outdoor unit, a large amount of vibration may be generated due to the compression action of the refrigerant. Such vibration may be applied to a refrigerant pipe around the compressor, for example, a suction pipe or a discharge pipe of the compressor. The vibration may concentrate the stress on the refrigerant pipe, which may adversely affect the rigidity of the refrigerant pipe.

The applicant of the present application has filed the following prior art reference to an air conditioner having an apparatus for attenuating vibration of the refrigerant pipe.
