Heat absorption assembly and heat collector

The embodiment of the invention relates to a heat exchange device, in particular to a heat absorption assembly and a heat collector, the heat absorption assembly is arranged on the heat exchange device of the heat collector, the heat absorption assembly comprises a plurality of vacuum tubes arranged on the heat exchange device in the preset direction, and each vacuum tube comprises an inner wall arranged relative to the heat exchange device and an outer wall arranged away from the heat exchange device; a vacuum cavity capable of blocking heat transfer is formed between the inner wall and the outer wall; the inner wall and the outer wall are bent in the direction away from the heat exchange device, so that the inner wall and the outer wall form outwards-protruding arc-shaped walls, and a heat conduction cavity capable of conducting heat is formed between the inner wall and the heat exchange device. Compared with the prior art, the heat absorption assembly has the same heat collection area, and meanwhile, each
