specific Embodiment 1

[0037] Such as figure 1 As shown, the cabinet includes a cabinet body, and a server 1 , a cooling medium, and a server cooling device for cooling the server 1 through the cooling medium are arranged in the cabinet. In this example, if Figure 1 to Figure 4 As shown, the server cooling device includes a fog cooling chamber 2. The fog cooling chamber 2 includes a chamber body 3 and a chamber door 4. The chamber door 4 is sealed and installed on the front side of the chamber body 3. The chamber door 4 includes 12 strip-shaped sealing plates 5 , there are 12 servers 1 placed in the fog cold chamber 2, and the 12 servers 1 are placed upright in the fog cold chamber 2 at intervals, and each server 1 is arranged corresponding to the width and position of the strip-shaped sealing plate 5 on the front side, each Each strip-shaped sealing plate 5 can be disassembled or installed independently, so as to facilitate the installation, maintenance and disassembly of each server 1.

specific Embodiment 2

[0051] It differs from Embodiment 1 in that: as Figure 5 As shown, no cooling device, cooling fan and heating parts are arranged in the cabinet, the circulation pump is arranged outside the cabinet, the cabinet is a sealed cabinet, the cabinet forms a fog cold storehouse 16, and the cabinet door is the door 17 of the fog storehouse 16, Servers 18 are arranged at intervals in the mist cooling chamber 16 along the up and down direction, and the conveying pipe 19 is extended and arranged along the up and down direction. The conveying pipe 19 is provided with spray holes facing the direction of the servers horizontally. The cooling medium is single-phase cooling liquid. The cooling working fluid is output from the spray hole 20 and enters into the server 18 to cool the heat-generating components in the server 18 .

[0052] In this embodiment, the atomized cooling medium has better diffusivity, and can be adapted to the arrangement of servers arranged at intervals along the vertic...

specific Embodiment 3

[0056] The difference from Example 1 is that the cooling medium is a phase-change cooling medium, and the specific cooling medium is a fluorinated liquid. The atomized fluorinated liquid enters the server and contacts the heat-generating components of the server. During the heat exchange process of the components, the fluorinated liquid is vaporized, and the vaporized fluorinated liquid flows downward along with the atomized fluorinated liquid entering the server to enter the fluorinated liquid stored at the bottom of the mist cold chamber. In the liquid, under the action of the cooling coil, the vaporized fluorinated liquid releases heat to form a liquid, which is re-atomized by the atomizer for the next cycle.

[0057] In this embodiment, in order to improve the cooling efficiency of the server, the fan in the server can be used to increase the flow speed of the vaporized fluorinated liquid in the server.

Abstract

The invention relates to a cabinet and a server cooling device. The server cooling device comprises a fog cooling bin, an atomizer and an in-bin heat exchanger. The fog cooling bin is provided with asealing cavity used for containing all or part of a server, and the sealing cavity is further used for storing a cooling working medium; the atomizer is located in the fog cooling bin and used for atomizing the cooling working medium to enable the atomized cooling working medium to cool the server, and the in-bin heat exchanger is arranged in the fog cooling bin and used for cooling the cooling working medium in the fog cooling bin. The server is cooled through the atomized cooling working medium; compared with a spraying cooling mode in the prior art, the atomized cooling working medium has better diffusivity, the heat dissipation and cooling of the upward, horizontal and downward outer surfaces of the heating part in the sealed cavity can be achieved, the cooling uniformity of the servercooling device can be improved, the server cooling device can adapt to installation modes of various servers, and the server cooling device has good adaptability.

Description

technical field [0001] The invention relates to a cabinet and a server cooling device. Background technique [0002] With the vigorous development of information technologies such as big data, Internet + and cloud computing, data centers, as the necessary infrastructure for information technology, are gradually developing in the direction of large-scale and high-density development. A prominent problem brought about by the high-density development of electronic information equipment It is a sharp increase in the heat generation of the server in the cabinet. [0003] Most server cabinets in commercial data centers are cooled by air. The small specific heat capacity of air and large heat transfer temperature difference lead to low cooling efficiency and high energy consumption. In order to improve the cooling efficiency and reduce the energy consumption, in the prior art, liquid-cooled cabinets such as indirect cooling cold plate cabinets, bathtub-type liquid-cooled cabinets ...
