Abstract

The invention provides a solar cooker which comprises a concentrator, a heat collecting pipe, a thermal insulation pipe, a thermal insulation pot and a support. The concentrator is a reflective film parabolic cylinder concentrating panel. The heat collecting pipe is fixedly arranged on the concentrator. The axis of the heat collecting pipe coincides with the focal line of the concentrator. The heat collecting pipe, the thermal insulation pipe and the thermal insulation pot communicate in sequence in the shortest distance. The axis of the heat collecting pipe coincides with the focal line of the concentrator, and perfect matching between the solar focal line and the appearance of the heat collecting pipe is achieved; and in addition, the concentrating portion and the thermal insulation pot part are located on the two sides of the thermal insulation pipe correspondingly, contamination of the thermal insulation part is not spread to the concentrating portion, and the service lives of the concentrator and the heat collecting pipe are prolonged greatly.
