AI Technical Summary

Technical Problem

In existing air conditioners, insufficient straight pipe length leads to poor refrigerant consistency at the distributor, causing an imbalance in refrigerant distribution between capillary tubes, which affects the heat exchange efficiency of the evaporator and condenser and the overall system performance.

Method used

The system adopts an inlet connection structure, including an inlet pipe and a turbulence pipe. The inlet pipe and the turbulence pipe are connected at one end in the middle and form an angle. The refrigerant undergoes turbulent mixing in the turbulence pipe to ensure that the refrigerant has a high degree of consistency before entering the distributor.

Benefits of technology

It improves the uniformity of refrigerant distribution in the distributor head, enhances refrigerant distribution between capillary tubes, and improves the heat exchange capacity of the evaporator and condenser.

Abstract

本实用新型公开了一种入口连接结构，用于与分配头相连且其包括入口管以及与入口管相连的扰流管，所述扰流管一端密封且其另一端用于与分配头相连；所述入口管一端连接在扰流管中部且其与扰流管的轴线之间形成有一定夹角；与现有技术相比，将所述入口连接结构应用到空调器中，来与分配头和若干毛细管配合形成空调器的分配器，在入口管导入冷媒进入到扰流管后，冷媒在扰流管进行湍流，与现有的分配器中的直管段相比，并未增加其长度，来使冷媒在进入分配头前混合的均匀度相对较优，冷媒进入到分配头内具有良好的一致性，则使各毛细管的冷媒分配均匀，有利于提高空调器中的蒸发器和冷凝器的换热能力。
