Heat flow adjusting system and automobile

The invention relates to a heat flow adjusting system and an automobile, and relates to the technical field of heat exchangers. The invention provides a heat flow adjusting system which comprises an outer pipeline, an inner pipeline, an inner pipeline, a heat exchanger and a heat flow adjusting device. The outer pipeline is internally provided with a containing cavity and an outer pipeline fluid cavity; the inner pipeline is arranged in the containing cavity of the outer pipeline in a penetrating mode, and an inner pipeline fluid cavity is formed in the inner pipeline; and the heat conduction assembly is partially and movably arranged between the inner pipeline fluid cavity and the outer pipeline fluid cavity, and the heat conduction assembly can change the contact volume of the heat conduction assembly between the inner pipeline fluid cavity and the outer pipeline fluid cavity through movement so as to adjust heat transfer parameters between the inner pipeline fluid cavity and the outer pipeline fluid cavity
