The invention discloses a light device for efficient heat dissipation of cubic satellite electronic equipment, and belongs to the technical field of aerospace. The invention solves the problems that the existing cubic satellite electronic equipment is limited in heat dissipation area, too many parts are required by a heat transfer path, a thermal resistance is relatively large, the heat dissipation of high-power electronic equipment is not facilitated, and the cubic satellite is difficult to normally operate in an on-orbit business mode. A second heat conduction copper layer is clamped between the upper insulating material plate and the lower insulating material plate in parallel, the two third heat conduction copper layers are oppositely and fixedly installed at the two ends of the first heat conduction copper layer, sockets are installed on the top surface of the printed circuit board, and each socket is correspondingly connected with a pin header on the printed circuit board above the socket. Electrical connection between two adjacent printed circuit boards is realized, two ends of the plurality of printed circuit boards are correspondingly clamped in side surface grooves of the clamping groove type structure shells, and the top surface special-shaped end cover covers the top ends of the two clamping groove type structure shells.

    一种用于立方卫星电子设备高效散热的轻型装置,属于航空航天技术领域。本发明解决了现有的立方卫星电子设备散热面积有限,热量传递路径所需零件过多,热阻较大,不利于大功率电子设备的散热,使得立方卫星难以在轨业务化常态运行的问题。第二导热铜层平行夹装在上下两个绝缘材料板之间,第三导热铜层的数量为两个且相对固装在第一导热铜层的两端,印制电路板的顶面分别安装有插座,每个插座对应与其上方印制电路板上的排针连接,实现相临两个印制电路板之间的电气连接,若干印制电路板的两端对应卡装在卡槽式结构外壳的侧面凹槽内,顶部表面异形端盖盖装在两个卡槽式结构外壳顶端。
