The invention relates to a four-way mixing chamber for a radiation convection coupling aerodynamic heat test, which comprises an airflow cavity and a radiation cavity, and is characterized in that the airflow cavity comprises a small-end flange, a four-way inner shell, a four-way outer shell, an upstream flange, a large-end flange and a first air inlet ring; the four-way outer shell wraps the outer side of the four-way inner shell. The small-end flange is installed on one side of the small end of the four-way inner shell, the upstream flanges are installed on the two sides of the four-way inner shell, the large-end flange is installed on one side of the large end of the four-way inner shell, and the first air inlet ring is installed on the inner side of the large-end flange. The radiation cavity comprises a communicating flange, a radiation cavity inner shell, a radiation cavity outer shell, a radiation flange and a second air inlet ring, the radiation cavity outer shell wraps the radiation cavity inner shell, the communicating flange is installed at the large end of the radiation cavity inner shell, the radiation flange is installed at the small end of the radiation cavity inner shell, and the second air inlet ring is installed on the inner side of the radiation flange. When in use, the airflow cavity and the radiation cavity are connected together, and high-pressure cooling water and high-pressure cold air are respectively introduced into the airflow cavity and the radiation cavity. The device is mainly used for integration of a convection heat source and a radiation heat source and modulation of a convection heat source flow field in a radiation and convection coupling aerodynamic heat ground simulation test.
