Example Embodiment
[0036] In order to clearly describe the heat recovery card refrigeration device, the following terms and definitions apply to the entire specification.
[0037] T H (T h ): The temperature of the heat sink (hot end) of the electric card cooling device.
[0038] T c (T L ): The cooling load (cold end) temperature of the electric card cooling device.
[0039] E H (E h ): The maximum electric field acting on the cooling device in the embodiment of the present invention.
[0040] E L (or E L =0): the smallest electric field acting on the cooling device in the embodiment of the present invention.
[0041] ΔE=E H -E L : Indicates the change of electric field.
[0042] Electric snap ring: the outer diameter (OD), inner diameter (ID) of the circular electrical card component, thickness d, and the electrical snap ring has a low thermal conductivity (k <0.2W / mK) Multiple electrical card segments separated by spacers.
[0043] Area with or without electric field: The area described is fixed in space...
