Abstract

The invention provides a pipe joint device and a car air conditioner. The pipe joint device comprises a first pipe joint and a second pipe joint which is in butt joint with the second pipe joint, wherein the first pipe joint and the second pipe joint are sealed by an axial sealing part and a radial sealing part. The pipe joint device and the car air conditioner provided by the invention can be suitable for various road conditions in a car operation process, so that even a car is in a bumpy condition, a refrigerant leakage condition is avoided. Besides, sealing properties of the pipe joints are relatively high, so that a refrigerating system pressure resistance value of the pipe joint device can be increased, and therefore, the pipe joint device is applied to a refrigerant refrigerating system with relatively high operation pressure.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a pipe joint device and an automobile air conditioner. Background technique [0002] Among the types of failures of the existing automobile air conditioners, the leakage of the refrigerant in the refrigeration system is one of the most important causes of the failures of the automobile air conditioners. At present, the pipeline connection of the automobile air conditioner is usually connected by means of pipe joint crimping, and a rubber sealing ring is arranged in the radial direction of the pipe joint for sealing the pipeline connection. Because the road condition of the car is relatively complicated, and it is often in a violent bumpy state, the sealing performance of this structure using a single radial sealing ring is not reliable, and it is easy to cause refrigerant leakage. In addition, this kind of sealed structure is resistant to the low pressure value of the r...
