A support frame and a vacuum apparatus, relating to the technical field of vacuum apparatus. The support frame may include a main frame, support bars and support protrusions, wherein the structure of the main frame can match the outer contour of a surface to be supported of a heating device, and a plurality of support bars are arranged in the main frame, so that an object of any shape to be supported can be supported without deformation. In addition, a plurality of support protrusions are arranged on one surface of the main frame and the support bars, and the support protrusions are in contact with the surface to be supported of the heating device. When the heating device is placed on the support frame, each support protrusion can contact the heating device and provide a certain supporting force, thereby reducing deformation of the heating device.
