Heat exchanger

Abstract

A heat exchanger having an improved distribution structure in which one inlet pipe is connected to a header which is partitioned into a first sub-chamber in which a refrigerant flows through the inlet pipe and a second sub-chamber in which tubes communicate with each other, and a distribution pipe is installed at the header and causes the first sub-chamber and the second sub-chamber to communicate so that the refrigerant in the first sub-chamber can be distributed to the tubes. The distribution pipe can pass through and can be combined with a partitioning baffle that is combined with the header to partition a chamber of the header into the first sub-chamber and the second sub-chamber.

Description

technical field [0001] The following description relates to a heat exchanger, and more particularly, to a heat exchanger having a structure that improves refrigerant distribution. Background technique [0002] In general, a heat exchanger is a device that exchanges heat from a refrigerant with heat from the air outside the heat exchanger by using pipes, heat exchange fins, and headers in which the refrigerant It flows in the middle and exchanges heat with the air outside the heat exchanger. The heat exchange fins contact the pipe to increase the heat dissipation area, and the two ends of the pipe communicate with the header. The heat exchanger may include an evaporator or a condenser, and may constitute a refrigeration cycle device together with a compressor for compressing refrigerant and an expansion valve for expanding refrigerant. [0003] The heat exchanger may have an inlet pipe through which refrigerant outside the heat exchanger flows into the heat exchanger, and th...

Problems solved by technology

[0004] However, since an increase in the number of inlet pipes increases cost design space, a structure using only one inlet pipe while improving refrigerant distribution has been studied
