[0066] Optionally, the working fluid injected into the hot-end temperature equalizing plate 2 or the cold-end temperature equalizing plate 3 is a non-flammable inert material, which can be directly melted and packaged during packaging, or more reliably, a metal extension section is connected to the vacuum injection port in advance, which can be connected by welding, and then the extension section is vacuumed and injected for packaging.
[0067] Optionally, the hot end temperature plate 2 includes a first evaporation end 21 and a first condensation end 22, wherein the first evaporation end 21 is attached to the hot end 12 of the electric card refrigeration module, and the first evaporation end 21 is arranged below the first condensation end 22.

[0068] The temperature averaging plate type electric card refrigeration device provided in the embodiment of the present disclosure adopts a hot end temperature averaging plate 2 and a cold end temperature averaging plate 3 to receive and separate the heat and cold of the electric card refrigeration module. After the first evaporation end 21 of the hot end temperature averaging plate 2 receives the heat, it quickly transfers it upward to the first condensation end 22, thereby separating the heat of the electric card refrigeration module. After the second condensation end 31 of the cold end temperature averaging plate 3 receives the cold, it quickly transfers it downward to the second evaporation end 32, thereby separating the cold of the electric card refrigeration module. Figure 3 shown.
[0069] Specifically, the phase-change temperature plate can be self-starting. Its working principle is that there is a closed flow path in the temperature plate, and the working fluid is evacuated and perfused into it. The lower part is the evaporation end, and the upper part is the condensation end. The first evaporation end 21 of the hot end temperature plate 2 is assembled with the electric card refrigeration module, and the second condensation end 31 of the cold end temperature plate 3 is assembled with the electric card refrigeration module. The boiling point of the first working fluid in the hot end temperature plate 2 is higher than the boiling point of the second working fluid in the cold end temperature plate 3, and the specific temperature point is based on the temperature point where the electric card refrigeration module needs to separate the hot and cold.
[0070] When the power is on and the heat is released, the first working fluid absorbs heat and evaporates at the first evaporation end 21 of the hot end temperature equalizer 2. The steam moves up to the first condensation end 22 under the action of density difference. The first working fluid condenses and releases heat at the first condensation end 22, and the heat is uploaded and condensed into liquid. Under the action of gravity, the condensation flows back to the first evaporation end 21, and the work is circulated in the next working cycle. When the power is off, the second working fluid absorbs cold and condenses into liquid at the second condensation end 31 of the cold end temperature equalizer 3. Under the action of gravity, it flows downward to the second evaporation end 32, absorbs heat at the second evaporation end 32. Because the second working fluid has a lower boiling point, the second working fluid becomes gaseous. Under the action of density difference, the steam of the second working fluid moves up to the second condensation end 31, and the work is circulated in the next working cycle.
[0071] Optionally, the electric card refrigeration module also includes a packaging shell, and the packaging shell of the electric card refrigeration module is assembled with the hot-end temperature equalizing plate 2 and the cold-end temperature equalizing plate 3 for heat exchange, and the packaging shell and the temperature equalizing plates at both ends are tightly connected as a whole through thermal conductive glue, thermal conductive silicone grease or welding, thereby reducing contact thermal resistance and ensuring tight and efficient heat transfer between the contact surfaces of the electric card refrigeration module and the temperature equalizing plates at both ends.
[0072] Optionally, the area of the first evaporation end 21 of the hot end temperature equalizer plate 2 is less than or equal to the area of the first condensation end 22.
