[0003] In existing technologies, improving the cooling effect of liquid chillers is generally achieved by increasing their power. However, increasing the power of liquid chillers leads to their larger size, which is detrimental to the design and layout of standard energy storage container systems. Utility Model Content

A semiconductor refrigeration device 13 is installed on the outside of the liquid cooling unit compartment 12. The semiconductor refrigeration device 13 forms an air duct with the liquid cooling unit 14 or with the liquid cooling unit compartment 12. Air is cooled and lowered through the air duct before entering the liquid cooling unit 14.

[0038] Figure 2 This is a schematic diagram of a thermoelectric cooling device 13. The thermoelectric cooling device 13 consists of multiple thermoelectric cooling chips 16 arranged inside a heat sink 15. The hot ends of the thermoelectric cooling chips 16 are attached to the heat sink, while the cold ends are exposed to the air.
