[0035] The present application will be described below Figs. 1 to 4 A suspension type data center cooling device is described in the embodiments of the present application, comprising a plurality of overhead ventilation layers 1, a plurality of suspension fixing members 2 and a plurality of server cooling mechanisms 3;
[0036] A plurality of said overhead ventilation layers 1 are arranged in the vertical direction, and overhead columns 11 are arranged between said overhead ventilation layers 1;
[0037] Said overhead ventilation layer 1 is composed of a plurality of full-paved passage areas 12 and a plurality of ventilation areas 13; said ventilation area 13 penetrates through the upper and lower sides of said overhead ventilation layer 1;
[0038] Said server cooling mechanism 3 is filled with cooling liquid 31, and data servers are installed in said cooling liquid 31;
[0039] A plurality of said suspension fixing members 2 are arranged on the bottom surface of the upper layer of said overhead ventilation layer 1, and a plurality of said server cooling mechanisms 3 are respectively detachably arranged on said suspension fixing members 2; and said server cooling mechanism 3 is located directly above said ventilation area 13.
[0040] Specifically, in the prior art, for the cooling of servers in data centers, the servers are usually stored in air-cooled system machine rooms with air conditioning refrigeration, and the cold air blown by the air conditioner is used to cool the servers, but the air-cooled system has the problems of high transmission and distribution loss, low transmission and distribution temperature, high cost, inability to achieve high energy efficiency operation, etc. In addition, liquid cooling systems such as cold plate liquid cooling, immersion liquid cooling, spray liquid cooling, etc. can achieve much higher cooling energy efficiency than air cooling, but the current liquid cooling system still needs energy-consuming systems such as water pumps and cooling towers, and cannot achieve completely free cooling.
[0041] The following is described in the specific implementation, the overhead ventilation layer 1 with rigid ventilation overhead ground as the floor of each layer, the overhead ventilation layer 1 of the top layer as the roof of the whole cooling device, the overhead ventilation layer 1 is supported by overhead column 11, whether the overhead ventilation layer 1 of the roof or the overhead ventilation layer 1 below the roof, adopts the way of partial full paving and partial ventilation, the full paving channel area 12 is used as a pedestrian walkway, the full paving channel area 12 is the area where people walk, and the stainless steel ground is set in the form of support, the ventilation area 13 is set between the full paving channel area 12, the data server is installed in the server cooling mechanism 3 and operates, the heat emitted by the data server will be quickly absorbed by the cooling liquid 31 in the server cooling mechanism 3, and will be emitted outward, the heat emitted will be absorbed by the air around the server cooling mechanism 3, and due to the high temperature of the air, it will flow upward under the action of air pressure, the hot air will go up and pass through the ventilation area 13, and will rise layer by layer, and finally will be emitted to the atmosphere after passing through the overhead ventilation layer 1 of the roof, and after the hot air rises, a negative pressure will be formed between the overhead ventilation layer 1, and the relatively low temperature air around the overhead ventilation layer 1 will enter the space between the overhead ventilation layer 1 to supplement, so as to form the flow of air, realize the transfer of server heat to the atmosphere, in addition, the suspension fixing part 2 also plays a role in heat transfer, and the heat is emitted to the overhead ventilation layer 1 and the surrounding air, so as to improve the heat dissipation efficiency and improve the heat dissipation effect of the data server; the server cooling device is installed on the bottom surface of the overhead ventilation layer 1 through the suspension fixing part 2, and then the server cooling device and the suspension fixing part 2 are detachably connected, and the specific implementation can be connected through a screw port, and the falling prevention buckle and other structures are matched to realize that when it is necessary to maintain the server, the server cooling device can be detached from the suspension fixing part 2, which is simple and convenient to operate.
[0042] Compared with the air cooling system of the prior art, the ventilation area 13 of the overhead ventilation layer 1 structure realizes natural ventilation, the heat of the data server is absorbed by the cooling liquid 31, and the heat emitted by the server cooling mechanism 3 is absorbed and taken away by the flowing air, so as to realize cooling; it is not necessary to design a special machine room for cooling, and it is not necessary to cool the air in the machine room by a large number of cooling equipment such as air conditioners to absorb the heat of the data server, so as to reduce the cost of building the machine room, and at the same time, the cost of the cooling equipment and the energy consumption cost required by the cooling equipment are reduced.
[0043] Compared with the liquid cooling system of the prior art, the cooling liquid 31 around the data server in the device will flow upward under the action of thermal pressure after absorbing heat, so that the cooling liquid 31 forms a convection motion in the server cooling mechanism 3, and the flow of the cooling liquid 31 can improve the speed of heat dissipation. The flow of the cooling liquid 31 does not require any external power and can achieve completely free cooling. It is worth noting that the cooling liquid 31 in the embodiment should be a non-phase change liquid in the temperature range of 0-8 degrees Celsius under normal pressure.
[0044] In addition, on rainy days, rainwater can pass through the ventilation area 13 of the air-ventilated layer 1 and drop on the outer periphery of the server cooling mechanism 3. The scouring of the rainwater can take away the heat of the server cooling mechanism 3, further improving the efficiency of heat dissipation. To prevent exposure oxidation and the influence of rainwater, multiple measures are taken for each metal structure, such as using stainless steel material, galvanized coating, and setting a protective layer on the outer periphery of the server cooling mechanism 3 to ensure heat conduction while avoiding exposure oxidation and the influence of rainwater, effectively protecting the internal structure of the server cooling mechanism 3.

To effectively ensure the efficiency of heat dissipation, the proportion of the area of the ventilation area 13 to the total area of the air-ventilated layer 1 is not less than 45%. If the proportion of the area of the ventilation area 13 is too small, it will affect the dissipation of air and cause low heat dissipation efficiency. If the proportion of the area of the ventilation area 13 is too large, the area of the full-paved passage area 12 will be compressed, and the air-ventilated layer 1 will be unstable.
