Protected Electronic Device

The invention provides a protected electronic device. The electronic device includes an electronic component and a protective shield including a phase change material having a phase change temperatureof between 20 DEG C and 90 DEG C, an antivibration gel having hyperelastic and/or viscoelastic behavior at 20 DEG C, and a separation barrier positioned so as to separate the phase change material and the antivibration gel. The antivibration gel is positioned, at least partly, in contact with the electronic component, and has a thermal conductivity of greater than 1 W/m.K at 20 DEG C. 本发明涉及种防护电子设备。该电子设备，包括：电子部件(12)；防护罩，包括：相变温度在20℃和90℃之间的相变材料(20)，在20℃具有超弹性和/或粘弹性的防振凝胶(16)，设置成分离相变材料和防振凝胶的分隔屏障(18)，所述防振凝胶设置成至少部分地与电子部件接触，并且具有在20℃时大于1W/m.K的热导率。
