Abstract
The invention discloses a display cabinet. The display cabinet comprises a box body, an inner liner and an evaporator, wherein the box body is used for bearing internal components; the inner liner is arranged in the box body; at least one layer of shelf is arranged inside the box body; the shelf divides the interior of the inner liner into at least two layers of storage space; the evaporator adopts a micro-channel heat exchanger and is fixed on the bottom surface of the shelf. The display cabinet adopts the micro-channel heat exchanger to replace the original evaporator, and as the size of the micro-channel heat exchanger is small and can be mounted or fixed on the bottom surface of the shelf, the space in the inner liner is sufficiently utilized; on the other hand, as the evaporator is arranged on the shelf of the inner liner, and a local heat exchange space is formed inside each layer of storage space, the temperature is more uniform; in addition, as the micro-channel heat exchanger is fixed on the shelf, the overall strength of the shelf can be enhanced.
