The invention provides a one-way heat conduction space radiant cooler without depending on external source drive. The one-way heat conduction space radiant cooler comprises a radiator, a heat conduction plate, a plurality of shape memory alloy reeds and a reset spring, the radiator is arranged on a heat conduction plate, and the shape memory alloy reeds are attached to the periphery of the bottomof the radiator; the reset spring is arranged at the center of the bottom of the radiator, two ends of the reset spring are respectively fixed with the center of the bottom of the radiator and the heat conduction plate; and the shape memory alloy reeds deform according to the memory temperature so that the radiator is separated from or contacted with the heat conduction plate. The radiant cooler has extremely low requirements on platform installation, has a wide application prospect, and can perfectly realize one-way thermal conduction.

    本发明提供了一种不依靠外源驱动的单向热导通的空间辐冷器,包括散热器、导热板、多个形状记忆合金簧片以及复位弹簧,所述散热器安装在导热板上,所述形状记忆合金簧片贴装设置在散热器底部外围;所述复位弹簧设置于散热器底部中心,两端分别与散热器底部中心、导热板固定;形状记忆合金簧片根据记忆温度发生形变,使散热器与导热板分离或接触。本发明提供的辐冷器对平台安装要求极低,具有广泛应用的前景,能够完美实现单向热导通。
