Abstract

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes through which a refrigerant flows, a header including a tube connection part coupled to the plurality of refrigerant tubes and a refrigerant inflow part, a first pipe provided in the header to define a first flow space for the refrigerant, a second pipe surrounding the outside of the first pipe to define a second flow space for the refrigerant, and a communication hole defined in the first or second pipe to allow the refrigerant to pass therethrough.

Description

Technical field [0001] The present invention relates to heat exchangers. Background technique [0002] The heat exchanger is a constituent element of the refrigeration cycle, and is configured such that the refrigerant can flow. Also, the heat exchanger performs a function of cooling or heating air through heat exchange with air. The above-mentioned heat exchanger can be used in refrigeration devices such as air conditioners and refrigerators, and functions as a condenser or an evaporator depending on whether to condense or evaporate the refrigerant for heat exchange. [0003] This type of heat exchanger is roughly classified into a fin-and-tube type and a micro-channel type according to its shape. The above-mentioned fin-tube type heat exchanger includes a plurality of fins and tubes having a circular shape or a similar shape passing through the above-mentioned fins, and the above-mentioned micro-channel type heat exchanger includes a plurality of flat tubes (Flat tubes) through...
