The heat transfer channels comprise radiating patches, heat absorbing parts, heat-sensitive permanent magnet steel driving devices and the middle sheets; and each sunning protection heat transfer channel has two stable states including a starting heat-conduction state and a closing heat-insulation state, and the middle sheets are synchronously or asynchronously in heat transfer connection with the heat absorbing parts and the radiating patches in the starting heat-conduction states or the closing heat-insulation states. The embedded pressure reduction idle sunning protector is characterized in that the radiating patches are provided with heat transfer interfaces arranged among the inner surface of a circular sealed end of a covering glass pipe and the middle sheets, the heat-sensitive permanent magnet steel driving devices comprise heat-sensitive permanent magnet steel and soft iron driving pairs and bimetal sheet boosting components; and the bimetal sheet boosting components deform to assist in pushing the permanent magnet steel and soft iron driving pairs to be actuated in a cooling procedure when heat-sensitive permanent magnet steel in a demagnetized state is switched into a magnetized state. The embedded pressure reduction idle sunning protector has the advantages that the low-power heat transfer channels can guarantee that the pressure of steam in the heat pipe is not higher than twice the atmospheric pressure during idle sunning, and the embedded pressure reduction idle sunning protector is high in reliability.

An embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector consists of more than one idle sunning protection heat transfer channels and is arranged in a vacuum heat-insulating layer at the tail end of a vacuum heat pipe heat collecting element. Each idle sunning protection heat transfer channel consists of a heat radiating paster, a heat sink, a heating power drive device provided with an interface in heat-transfer connection with a heat pipe or an inner glass pipe, and a middle piece in transmission connection with the heating power drive device or integrally manufactured with the heating power drive device. The embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector has two types of stable states, namely an opening heat-conducting state when the middle piece is in heat-transfer connection with the heat sink and the heat radiating paster at the same time, and a closed heat-insulating state when the middle piece is not in heat-transfer connection with the heat sink and the heat radiating paster at the same time. The embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector is characterized in that the heat radiating paster includes an interface connected with the inner surface of the bottom end position of a cover glass pipe round sealing end and an interface performing heat transfer with the middle piece. Water vapor pressure inside a 70-watt heat collecting element heat pipe can be ensured not to exceed two atmospheric pressures through one idle sunning protector with10-watt heat radiating power, and the reliability is high.
