The invention provides a heat exchanger integrated assembly. The heat exchanger integrated assembly comprises a heat exchanger, an adaptation connecting device and an installation supporting frame used for fixing the integrated assembly, wherein one end of the adaptation connecting device is fixed to a matching part, and an outwards protruding third pipeline and an outwards protruding fourth pipeline are arranged at the other end of the adaptation connecting device; the installation supporting frame comprises an installation part bent at an included angle with the matching part, the installation part comprises at least two installation plates, at least one installation plate is located on the side, opposite to the side where the other installation plate is located, of the matching part, or the installation part comprises one installation plate and at least two connecting parts, and the gap between at least two adjacent connecting parts is larger than the gap between other adjacent connecting parts. Each installation plate is provided with a plurality of installation holes, and the installation holes are completely exposed outside the heat exchanger and the adaptation connecting device in the installation direction penetrating through the installation holes. The heat exchanger integrated assembly is simple in structure, good in refrigeration effect, high in stability of the installation supporting frame and high in vibration strength.
