The invention discloses a heat pipe type solar thermal collector using solid media to exchange heat. The heat pipe type solar thermal collector comprises a solar union collection box, a frame, a solar thermal collection pipe, a heat exchange coil and a high thermal conductive graphite heat exchange layer. The frame is arranged at the periphery of the solar union collection box, the solar thermal collection pipe comprises an evaporation section and a condensation section, the evaporation section is arranged out the solar union collection box and fixed on the frame, the condensation section is positioned in the solar union collection box, the heat exchange coil is arranged in the solar union collection box, the condensation section of the solar thermal collection pipe is arranged at the gap portion of the heat exchange coil, and the high thermal conductive graphite heat exchange layer covers the solar thermal collection pipe. The heat pipe type solar thermal collector is high in heat collection efficiency, quick in heat transfer speed, capable of resisting to high temperature, capable of resisting to air drying, capable of resisting to low temperature and capable of resisting to freezing. The heat pipe type solar thermal collector overcomes the defects that the solar thermal collection pipe is small in external heat transfer surface area, energy is relatively concentrated, incrustation is prone to depositing to affect heat exchange effects, and a full-glass tube is prone to exploding in a comminuted mode to leak water.
