The utility model relates to the technical field of vacuum heat insulation equipment, and discloses a support column for increasing heat conduction resistance, which comprises a vacuum heat insulation
assembly. According to the supporting column capable of increasing the heat conduction resistance, heat conduction paths can be increased through the formed triangular holes instead of simple linear conduction, direct conduction of
heat flow can be effectively disturbed due to the three-side angles of the triangular holes, heat can be conducted to the outer container from the inner container only through a longer path, and compared with a round or square hole, the heat conduction resistance is greatly improved. Triangular holes can guide the direction of
heat flow, the propagation distance of the
heat flow can be increased by turning back, so that the heat conduction resistance is improved, a higher heat insulation effect is achieved, the
aerogel layer, the vacuum heat insulation plate, the
polyurethane foam layer and the second aluminized
polyester film are matched with one another,
structural distribution of the gradually-changed heat
insulation layer can be achieved, and the heat insulation effect is improved. The inner end and the outer end of the supporting column body are made of different materials and have different thicknesses, so that
temperature difference transition is smooth, and thermal stress caused by overlarge
temperature difference is avoided.
