The invention discloses a solar insulation box for outdoor electronic equipment in an alpine region, and belongs to the technical field of solar utilization equipment. The device comprises a box body, a fixing structure, an insulation module, a solar heat collecting module, connecting pipes and a cooling module. The solar heat collecting module and the cooling module are integrated; liquid in a heat collecting pipe is heated through acquiring solar energy; the interior of the box body is heated by using natural convection; and the installation, the disassembly and the maintenance are convenient. In addition, the box body is provided with a movable door, a door lock and a protective edge; elements and electronic equipment in the box can be protected; and the placement and the removal of the electronic equipment are convenient. The solar insulation box directly uses the solar energy for heating the liquid, omits conversion, energy storage and electric heating modules, effectively saves the cost, is simple in structure, and can be widely applied to insulation and protection of the electronic equipment in the alpine region.
