The invention discloses a space radiation radiator. The space radiation radiator comprises a main pipeline; the heat dissipation assembly is provided with a hollow cavity, the cavity is communicated with the main pipeline, a heat-carrying working medium is arranged in the cavity and used for absorbing heat of the spacecraft, and at least one side wall of the heat dissipation assembly is an infrared glass plate so that the heat of the heat-carrying working medium can penetrate through the infrared glass plate to be radiated outwards. The heat dissipation assembly comprises two infrared glass plates arranged in parallel and two branch pipelines arranged in parallel. And the branch pipelines are located at the two ends of the cavity correspondingly, both the branch pipelines are connected with the main pipeline, and the branch pipelines communicate with the cavity so that the heat-carrying working medium can enter the cavity through the branch pipelines. By the adoption of the method, the heat dissipation efficiency of the spacecraft can be effectively improved, compared with a traditional mode, the system structure is simplified, and then the machining difficulty and the production cost are reduced.
