Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to a splitter for air conditioning units. Background Technology

[0002] In air conditioning systems, refrigerant distributors are frequently used to improve heat exchange efficiency. A distributor typically consists of a distributor head and a main pipe. A mixing chamber is formed between the outer wall of the distributor head and the inner wall of the main pipe, and the connection between the distributor head and the main pipe is fixed by welding.

[0003] For example, Chinese Patent Publication No. CN112444011A discloses a distributor for an air conditioning unit, belonging to the field of air conditioning technology. The invention includes a distributor head and a main flow pipe. The distributor head includes a distributor hole section and a cavity section. The inner wall of the end of the cavity section is chamfered. The main flow pipe is divided into an assembly section, an inclined section and an inlet section connected in sequence along its length. In this invention, the outer side of the end face of the assembly section is interference-fitted with the inner wall of the cavity section, and the outer side of the end of the assembly section is tangent to the chamfer of the inner wall of the end of the cavity section. This avoids the molten droplets after heating flowing into the mixing chamber from the gap between the main flow pipe and the distributor head during welding and fixing, thereby blocking the mixing chamber.
