the housing 7 is made of a fluorescent material containing thermochromic material, and is provided with a display module 4.

Example 1:

thermochromic fluorescent materials, such as thermochromic films which are relatively more popular in price, are used in the shell of the SSD, thermochromic dyes are used on a finished product, electrons can be charged and programmed in the process of charging due to the electronic characteristics of NAND Flash when the SSD is used for writing data, the temperature of FLASH particles can be increased due to the heat generation in the process of charging, and heat can be generated when a controller of the SSD works.

when using thermochromic materials, different lamp band effects can be exhibited on the fluorescent material depending on the change in temperature. For example, a cold tone may be exhibited when the temperature is low, a colored tone may be exhibited when the temperature is at an operating temperature, and a warning tone, such as red or yellow, may be exhibited when the temperature exceeds a normal temperature.

Example 2:
