Abstract

The present invention discloses a cold / heat exchanger with vibration-damping structure. It is mainly characterized by that in the pipeline formed into circulating loop of said cold / heat exchanger a hose is used, and is connected with inlet end and outlet end of compressor, one end of said hose is connected with adapter, another end of said adapter is seal-connected with the described circulating loop, and the inside liner of hose tube body portion connected with the adapter has a lining tube made of rigid material. Besides, said invention also provides the concrete structure of said adapter and its fittings.

Description

technical field [0001] The invention relates to a cold and heat exchanger, in particular to a cold and heat exchanger with a vibration damping structure. Background technique [0002] The basic structure of existing cold and heat exchangers, such as air conditioners or refrigerators, is simply a cold and heat exchange loop connected by metal pipes, and the working principle of refrigeration is to achieve heat exchange through the cold and heat exchange loop. , the specific process is roughly as follows: the high-temperature and high-pressure gaseous refrigerant (refrigerant) produced by the compressor is cooled by the condenser to become a normal temperature and high-pressure liquid refrigerant, and then expands and expands through the capillary of the expansion valve to become a low-temperature and low-pressure liquid refrigerant, and absorbs heat through the evaporator Then it becomes a low-pressure gaseous refrigerant, which is then recycled to the compressor to be compre...

Problems solved by technology

[0003] The main defect of the above-mentioned common cold and heat exchangers that connect compressors, condensers, evaporators and other components together by metal pipelines is that the vibration generated by the compressor itself during operation will be transmitted to the condenser, condenser, etc. through metal pipelines. Other components such as the evaporator are even gradually transmitted and expanded in the entire circulation loop. When this vibration accumulates to a certain extent, its direct consequences are: affecting or destroying the sealing performance of the metal pipeline, accelerating the leakage rate of the refrigerant, and reducing the cooling capacity of the refrigerant. In addition, this kind of vibration is often accompanied by a kind of noise. In short, it is necessary to try to avoid this kind of vibration or try to block the smooth transmission of this kind of vibration. In fact, low noise and high stability It has always been a concern of manufacturers and consumers of this kind of cold and heat exchangers.

Although the hose has the function of blocking the transmission of compressor vibration and reducing noise, when it is applied to an air conditioner, the joint between the hose body and the hose, that is, the connection between the hose and the compressor, condenser, and evaporator Connection sealing performance: the tightness and stability of the seal are very important, otherwise, the leakage of the refrigerant will directly reduce the service life of the heat and cold exchanger, and the buckle-shaped joint interface cannot effectively prevent the leakage of the refrigerant, because in Located at the junction of the hose and the metal pipeline, often due to the incomplete and tight indentation or the irregular deformation of the hose during crimping, it is easy to form a gap where the refrigerant can slowly leak, especially when the air conditioner is used for a long time Later, this defect is more obvious, which is also an important reason why this technology is difficult to promote and use on a large scale.
