AI Technical Summary

Technical Problem

Existing heat exchangers face uneven refrigerant distribution due to the influence of inertial force, leading to inefficiencies in heat exchange.

Method used

A heat exchanger design that incorporates a refrigerant receiving tank with a swirl structure and laminated plates, adjusting the inlet height and channel distance to evenly distribute refrigerant using swirling components.

Benefits of technology

The design ensures more even refrigerant distribution, enhancing the efficiency of heat exchange by preventing excessive flow into specific inlets and optimizing refrigerant dispersion across all channels.

Abstract

To provide a heat exchanger capable of distributing refrigerant more evenly.SOLUTION: A heat exchanger 10 comprises a refrigerant receiving tank 61 that receives refrigerant, a refrigerant delivery tank that sends out the refrigerant after heat exchange, and a refrigerant flow path W10 that connects the refrigerant receiving tank 61 and the refrigerant delivery tank and exchanges heat with other fluid. The refrigerant receiving tank 61 is provided with a swirling blade 5 as a swirling structure that imparts a swirling component to the refrigerant to be received, and the swirling impeller is composed of a plurality of plates stacked one on top of another.SELECTED DRAWING: Figure 4
