The invention discloses an integrally packaged type solar heat collector with combined curved surface for light collection and vacuum tube for heat collection, belonging to the technical fields of solar light collection and medium and high temperature solar heat collection. The solar heat collector of the invention comprises a combined curved surface light collector, a vacuum tube heat collector, an adjustable tracker, a packaging shell and the like. After the sun light enters the combined curved surface light collector through a transparent glass cover plate, the sun light is reflected through an inner surface of the combined curved surface light collector and collected onto the vacuum tube heat collector, the vacuum tube heat collector absorbs the sun light to generate high-temperature heat energy, and the heat energy is conducted and transmitted to users by a heat conducting working medium in the vacuum tube heat collector. The invention can collect the sun light with low energy flow density after being reflected by a plurality of curved surfaces on the vacuum tube heat collector, thus the heat conducting working medium in the vacuum tube can be quickly heated to form high-temperature heat energy. The manually adjusted tracker can adjust the orientation of the combined curved surface light collector to track the sun, thereby enabling the heat collector to keep in the optimal sun light collecting state. The invention is especially suitable for use in high-latitude areas and in winter when the solar altitude is smaller.
