US Patent 9528778 Refrigerant guiding pipe and heat exchanger having refrigerant guiding pipe

A refrigerant guiding pipe having a pipe wall in which an inner chamber is formed, an opening formed in the pipe wall, and a refrigerant guiding portion. At least a part of the refrigerant guiding portion is disposed to be substantially inclined with respect to an axial direction of the refrigerant guiding pipe to guide refrigerant passing through the opening. The refrigerant guiding pipe can distribute and guide refrigerant well to help avoid non-uniform distribution of refrigerant due to layering of gaseous refrigerant and liquid refrigerant.
