The invention provides a refrigeration device. The refrigeration device comprises a box body which is provided with at least a storage chamber, wherein the box body comprises a top wall, a bottom wall, a pair of opposite side walls and a cross wall which is located between the top wall and the bottom wall and bridged between the pair of the side walls. The cross wall comprises a metal element which is located at the front end of the cross wall, and at least one of the side walls comprises a metal outer plate which is overlapped with the metal element in the depth direction of the storage chamber. The refrigeration device further comprises a heat insulation piece which is arranged between the metal element and the outer plate. Due to the fact that the heat insulation piece is arranged between the metal element and the side wall outer plate, cool air in the refrigeration device can be effectively prevented from passing to an external through connection between the metal element and the side wall outer plate, so that a phenomenon of moisture condensation at the position of the side wall outer plate is eliminated or reduced, and then a phenomenon of rusting on the side wall outer plate can be effectively avoided to prolong the service life of the refrigeration device.
