The vending machine body includes a metal shell and a transparent thin plate embedded in the metal shell. The transparent thin plate is generally embedded in the upper front and lower front of the metal shell. The upper transparent thin plate window serves as a transparent display window, and the lower transparent thin plate window serves as a retrieval window.

[0043] To reduce the impact of direct sunlight and ambient diffused light on the energy consumption of the vending machine in summer, and to further achieve a cooling effect and reduce energy consumption by dissipating the heat inside the vending machine through infrared radiation, this embodiment provides a radiative cooling layer on the outer surface of the vending machine body. The radiative cooling layer includes a reflective radiative cooling layer 1 and a transmissive radiative cooling layer 2.

[0045] In this embodiment, the reflective radiation cooling layer 1 is disposed on the outer surface of the metal shell, and the reflective radiation cooling layer 1 covers at least 80% of the outer surface of the metal shell, specifically it can cover 80%, 85%, 90%, 95%, or 100% of the outer surface of the metal shell.

[0046] In this embodiment, a color layer can be provided on the surface of the reflective radiation cooling layer 1 to make the vending machine more aesthetically pleasing.
