2. The server cooling device according to claim 1, wherein the atomizer is connected to a delivery pipe, and the delivery pipe is connected to an atomization outlet of the atomizer and is used for delivering atomized cooling medium to the server to cool the server.
3. The server cooling device according to claim 2, wherein the atomizer and the in-bin heat exchanger are both disposed in a portion of the bottom of the sealed chamber for storing the pre-atomized cooling medium.
4. The server cooling device according to claim 2 or 3, wherein the server cooling device further comprises a fan, the fan is mounted on the delivery pipe, and the air outlet direction of the fan is the same as the flow direction of the cooling working medium.
5. The server cooling device according to any one of claims 1 to 3, wherein the sealed chamber includes a server accommodating portion for storing the cooling medium before atomization and a cooling medium accommodating portion located above the cooling medium accommodating portion.
6. The server cooling device according to any one of claims 1 to 3, wherein the heat exchanger in the cabin comprises a cooling coil pipe, and a cooling liquid is introduced into the cooling coil pipe to cool the cooling working medium in the fog cooling cabin.
7. The server cooling device according to any one of claims 1 to 3, wherein the fog cooling chamber comprises a chamber body and a chamber door hermetically matched with the chamber body, the chamber door comprises at least two elongated sealing plates, each sealing plate is used for being arranged along the arrangement direction of the servers and is matched with the size of the servers, so that the corresponding server can be dismounted and mounted by dismounting the sealing plate.
8. A cabinet comprises a cabinet body, wherein a server and a cooling working medium are arranged in the cabinet body, and a server cooling device for cooling the server by the cooling working medium is further arranged, and the cabinet is characterized in that the server cooling device is the server cooling device as claimed in any one of claims 1 to 7.
9. The cabinet of claim 8, wherein a circulation pump is disposed in the cabinet and outside the fog cooling chamber, and the circulation pump is connected in series with the heat exchanger inside the chamber and is used for being connected in series with the heat exchanger outside the chamber, so as to cool the cooling liquid in the heat exchanger inside the chamber through the heat exchanger outside the chamber.
10. The cabinet according to claim 8, wherein a refrigerating device, a cooling fan and a heating component are arranged in the cabinet body, the refrigerating device cools the heating component under the action of the cooling fan, the refrigerating device comprises a condenser, a compressor and an evaporator which are connected in series, and the condenser extends into the fog cooling bin so as to cool the coolant in the condensing pipe by cooling working medium in the fog cooling bin.
