The invention provides a novel cabinet which is formed by splicing a plurality of side panels and a door plank, and the side panels or/and the door plank are made of composite plates composed of multiple layers of materials. Each composite panel comprises an upper panel layer, an upper compressive layer, a heat preservation layer, a lower compressive layer and a lower panel layer from top to bottom in sequence, the position between each upper panel layer and the corresponding upper compressive layer or/and the position between each lower panel layer and the corresponding lower compressive layer is/are filled with adsorbent, the upper panel layer or/and the lower panel layer is/are densely provided with micropores communicated with the adsorbent on the inner side(s) of the upper panel layer or/and the lower panel layer, activated carbon is adopted as the adsorbent, the thickness of the upper panel layer and the thickness of the lower panel layer range from 1 mm to 10 mm, the thickness of the upper compressive layer is the same as that of the lower compressive layer, the thickness of the upper compressive layer is one time and above larger than that of the upper panel layer, the thickness of the heat preservation layer is one time and above larger than that of the upper compressive layer, and the inner side face of the upper compressive layer or/and the inner side face of the lower compressive layer is/and provided with reinforcing ribs which are parallel to one another or intersect with one another. The novel cabinet has the functions of heat preservation, shock resistance, sound insulation and the like.
