The embodiment of the invention discloses a radiation heat dissipation device for an artificial satellite. The radiation heat dissipation device comprises a heat conduction belt; the radiation heat dissipation plate is rotatably connected with the edge of the star cabin plate through a rotating piece; the heat conduction belt extends into to-be-cooled equipment on the star through the upper surface of the star cabin plate from the radiation heat dissipation plate; the radiation heat dissipation plate comprises an unfolded state and a non-unfolded state; when the radiation heat dissipation plate is in the non-unfolded state, the radiation heat dissipation plate is attached to the outer side of the side wall of the star body; and when the radiation heat dissipation plate is in the unfolded state, the radiation heat dissipation plate is separated from the outer side of the side wall of the star body, so that heat of to-be-cooled equipment on the star body is conducted to the radiation heat dissipation plate through the heat conduction belt. According to the device, heat generated in to-be-cooled equipment on a star body is efficiently transmitted to the radiation heat dissipation plate through the flexible heat conduction belt, the heat is discharged to the outside through the radiation heat dissipation plate, rapid transfer and dissipation of high-density heat flow are achieved, the heat dissipation capacity of the star body is improved, and the device is simple in structure, light in weight, high in safety and high in reliability.

    本申请实施例公开了一种用于人造卫星的辐射散热装置,包括:导热带;通过转动件与星体舱板的边沿可转动连接的辐射散热板;导热带自辐射散热板经过星体舱板的上表面延伸至星体上的待散热设备中;辐射散热板包括:展开状态和非展开状态;当辐射散热板处于非展开状态时,辐射散热板贴合在星体的侧壁外侧;当辐射散热板处于展开状态时,辐射散热板与星体的侧壁外侧分离,以通过导热带将星体上的待散热设备的热量传导至辐射散热板。该装置通过柔性导热带将星体上的待散热设备中产生的热量高效传输至辐射散热板上,通过辐射散热板将热量排出至外界,实现高密度热流的快速转移和排散,提升了星体的散热能力,且构造简单、质量轻、安全性高、可靠性高。
