The utility model provides a heat exchanger which comprises a refrigerant flow path structure, the refrigerant flow path structure comprises a first pipeline, a second pipeline and a third pipeline, the first pipeline and the second pipeline are connected in series, one end of the third pipeline communicates with the first pipeline, the other end of the third pipeline communicates with the second pipeline, and meanwhile the refrigerant flow path structure further comprises a first valve body; the first valve body is arranged between the first pipeline and the third pipeline; when the heat exchanger is in a refrigeration working condition, the first valve body is closed at the moment, and a high-temperature and high-pressure refrigerant can directly enter the second pipeline from the first pipeline, so that the refrigerant can flow under the refrigeration working condition of the air conditioner; and when the heat exchanger completes the heating working condition and needs to flow back to the compressor again
