Heat insulation plate

The utility model relates to a heat insulation plate, and belongs to the technical field of plates. Comprising a bottom plate, partition plates, heat-insulating layers, a base plate and heat-insulating connecting assemblies. A base layer plate is arranged above the bottom plate through a heat insulation connecting assembly with a heat insulation function, a partition plate is arranged between the bottom plate and the base layer plate, and a heat insulation layer is arranged between the partition plate and the base layer plate. The heat insulation performance of the plate is effectively improved; by arranging the partition plate, the heat insulation cavity is divided into two parts, and the heat insulation performance of the plate is improved again; the heat insulation layer is arranged between the partition plate and the base layer plate, so that downward conduction of heat on the base layer plate is effectively blocked, and the heat insulation performance of the plate is further improved; the heat insulation
