Detailed Description
For a traditional data center machine room, 1 cold channel and 1 hot channel are generally required to be provided for two adjacent rows of cabinets to perform air cooling, the ratio of the floor area of the cabinets to the floor area of the channels is about 4: 3, and as a server installed in the cabinets bears a large amount of data calculation and storage, in order to meet the requirements of stability and high energy efficiency of new energy of the server, the requirement for good heat dissipation becomes a key, so that the spaces cannot be used as heat dissipation channels. However, for a pure liquid cooling data center machine room, the liquid cooling technology is utilized for heat dissipation, namely, liquid is adopted as a cooling medium means for heat dissipation for a server, and since air cooling does not exist, a heat dissipation channel can be omitted, and the use requirement can be met as long as a necessary working channel for maintenance operation is reserved.
The occupied area of a single machine cabinet of the current liquid cooling data center machine room is reduced to about 2.5-3 square meters, but the area really occupied by the machine cabinet is 0.72 square meter (namely, the length is 1.2 meters, and the width is 0.6 meters), and the rest are working channels, transportation channels and the like, so that the machine room still occupies a larger space, and the utilization rate of the area of the machine room is still lower. From this realize the utility model discloses an in-process discovery, on liquid cooling data center computer lab can omit heat dissipation channel's basis, if form a working channel in the rack the place ahead that needs maintenance operation through removing the liquid cooling rack, just can let traditional N be listed as the structure that the rack corresponds N passageway respectively and become that N is listed as the rack and only corresponds 1 passageway to greatly promote the computer lab area rate of utilization, and then effectively promote computer lab power density.
It should be noted that "liquid cooling" as used herein means cooling the server by circulating liquid to ensure stable operating temperature of the server, whereas "pure liquid cooling" means that all heat dissipation components of the server are cooled by liquid cooling without air cooling, and "server" means devices providing computing services, including file servers, database servers, application servers, and the like.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. Directional terms used in the embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., refer to directions of the drawings only, and do not limit the scope of the present invention. Throughout the drawings, like elements are represented by like or similar reference numerals. Conventional structures or constructions will be omitted when they may obscure the understanding of the present invention.
As an exemplary embodiment of the utility model provides a liquid cooling rack, specially adapted occasions such as data center computer lab for equipment such as placing server. Fig. 1 is a schematic side view of a liquid-cooled cabinet according to an embodiment of the present invention; fig. 2 is a schematic front view of a liquid-cooled cabinet according to an embodiment of the present invention; fig. 3 is a schematic top view of a liquid cooling cabinet according to an embodiment of the present invention.
