Cold edge simulation system for multi-channel radiator of iron bird test bench

An embodiment of the invention discloses a cold side simulation system for a multichannel radiator of an iron bird test bench, a cooling medium oil tank is sequentially connected with a cooling pump and an overflow valve, an outlet end of the overflow valve is divided into two cooling medium pipelines, one cooling medium pipeline is connected to a cold side pipeline inlet of a first radiator through a first throttle valve, and the other cooling medium pipeline is connected to a cold side pipeline outlet of a second radiator through a second throttle valve. The other path is connected to a cold side pipeline inlet of the second radiator through a second throttle valve; the return pipelines of the cold side pipeline outlets of the first radiator and the second radiator are connected to the cooling medium oil tank through the first cooling mechanism, and the second cooling mechanism and the cooling medium oil tank are installed in a matched mode to form a cooling loop. According to the technical scheme provided
