The invention discloses a gas chromatograph small-sized column box capable of heating and cooling. The gas chromatograph small-sized column box comprises a heat preservation upper cover, a temperature sensor A, a heating assembly, a chromatographic column bracket, a centrifugal impeller, a heat preservation shell, an air blower, a lifting door assembly and a driving motor, the centrifugal impeller, the heating assembly, the chromatographic column support and the chromatographic column are compressed and placed on the same layer, the space utilization rate is increased, the instrument size is reduced, the volume of air needing to be heated in the column box is also reduced, and the power needed by the instrument is reduced; according to the invention, the fin heating block is provided with a plurality of uniformly arranged large-area fins, so that the contact area between the fin heating block and the air is large, heat can be quickly transferred to the air, the heating efficiency is improved, the air in the c
