Referring to fig. 6, specifically, the first heat exchanger 220 of the first heat exchange device 200 includes a first cold channel 221, a first hot channel 222, which are isolated from each other, and further includes a micro-channel plate heat exchanger 223, the first cold channel 221 and the first hot channel 222 are formed by disposing a partition 225 in a box 224, a phase change material is filled in the micro-channel plate heat exchanger 223, the micro-channel plate heat exchanger 223 is obliquely disposed in the box 224 and penetrates through the partition 225, a portion of the micro-channel plate heat exchanger 223 located in the first cold channel 221 is a condensation portion, a portion located in the first hot channel 222 is an evaporation portion, and a first hot air outlet 1210 and a first cold air inlet 1220 at the top of the cabinet 100 are both communicated with the first hot channel 222. Similarly, the first fan assembly 210 of the first heat exchanging device 200 includes an outer circulation fan 211 and an inner circulation fan 212, the outer circulation fan 211 is configured to introduce the outside air into the first cold channel 221, the inner circulation fan 212 is configured to introduce the air in the first chamber 110 into the first hot channel 222 through the first hot air outlet 1210 and return the air to the first chamber 110 through the first cold air inlet 1220 to form air circulation, and the air in the first chamber 110 exchanges heat with the outside air in the first cold channel 221 in a circulation flow process to cool and dissipate the heat of the air in the first chamber 110, so as to dissipate the heat of the first charging unit 130.

Each micro channel of the micro channel plate type heat exchanger 223 is distributed in the first cold channel 221 and the first hot channel 222, so that the phase change material in the micro channel can quickly absorb or release heat to change phase, the heat exchange efficiency between air in the cabinet body is improved, the heat dissipation efficiency of the charger is improved, and the use reliability of the charger is improved.

In addition to the above embodiments, one of the first heat exchanging device 200 and the second heat exchanging device 300 may also be an air-cooled heat exchanging device, and the other one is a phase-change heat exchanging device, and the specific structure of the air-cooled heat exchanging device may refer to embodiment one and fig. 1 to 5, and the specific structure of the phase-change heat exchanging device may refer to embodiment two and fig. 6, which are not described herein again.

The utility model provides a charging station, including the machine and necessary power supply unit that charge in the above-mentioned embodiment, can refer to the configuration of charging station in the conventional art to power supply unit, do not restrict here and give unnecessary details.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
