Problems solved by technology

This situation affects the running quality of the server, and even causes the failure and damage of the server
[0003] With the advancement and rapid development of IT technology, high-density, high-power (high-heat) servers adopt cabinets with an integral structure of evaporating coils in the refrigeration system or chilled water coils prepared by air-conditioning units. In the cold mode, there is still a large temperature difference between the upper and lower servers on the N floor of the cabinet
At the same time, the cooling temperature of the cabinet is affected by changes in atmospheric temperature, humidity and server operating load temperature. Naturally produced evaporated water or condensed water coexists with the cabinet server and the complex power grid, as well as the abnormality of circulating liquids such as coils, joints, and valves. Explosion leakage failure, potentially endangering the operation safety of servers and databases

Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment provides an IT cabinet, in which a plurality of horizontal racks 11 are arranged, and the height of the horizontal racks can be adjusted arbitrarily, so as to be suitable for placing various IT equipments thereon, and the cabinet also includes fans and air ducts. 3. Multiple independently adjustable air volume regulating valves 4 and air outlets. The arrows in the figure show the flow direction of the cold air.

[0031] The fan in this embodiment adopts a single centrifugal fan 1, which is arranged below the inside of the cabinet and is used to extract cold air from the outside of the cabinet. The air duct 3 is formed on one side of the cabinet along the vertical direction inside the cabinet, and is used to guide the cold air introduced by the fan to each IT equipment arranged horizontally. The air volume regulating valves 4 are respectively arranged in the positions corresponding to the horizontal racks 11 in the air ...

Embodiment 2

[0039] Such as figure 2 As shown, the difference between Embodiment 2 and Embodiment 1 is that the fan adopts two centrifugal fans 2, which are respectively arranged in two independent spaces formed below the inside of the cabinet, and the bottoms of each independent space are respectively provided with air inlets. Each independent space also communicates with the air duct 3, so as to guide the external cold air drawn from the air inlet into the air duct. There is a backstop air valve at the position where each independent space communicates with the air duct 3, and each backstop air valve is synchronized with the corresponding centrifugal fan. When the two centrifugal fans are running, the backstop air valve is opened to make the centrifugal fan The cold air drawn by the fan enters the air duct; when only one of the centrifugal fans is running, the corresponding check air valve is opened, while the other check air valve is automatically closed due to the air pressure. In th...

Abstract

The invention provides a vertical homeothermy IT (Information Technology) cabinet, which is provided with a plurality of transverse stands, wherein the height of each transverse stand is freely adjustable, so that various IT equipment can be arranged on the stands adaptively. The cabinet further comprises a fan, an air channel, a plurality of independent adjustable air volume control values and an air outlet, wherein the fan is arranged on the upper part or lower part inside the cabinet and used for drawing cold air from outside; the air channel is arranged at one side of the cabinet along a vertical direction inside the cabinet and used for guiding the cold air introduced by the fan to each transversely arranged IT equipment; the plurality of independent adjustable air volume control valves are respectively arranged on positions, corresponding to the transverse stands, in the air channel from top to bottom so as to independently adjust the volume of air introduced into each IT equipment from the air channel and thus realize the vertical homeothermy inside the cabinet; and the air outlet is arranged on one side, opposite to the air channel, of the cabinet. According to the invention, an air cooling manner is adopted to cool the cabinet and realize the vertical homeothermy of the interior of the cabinet so as to guarantee the safe and reliable operation of the IT equipment inside the cabinet, and the cabinet is suitable for IT equipment of various specifications and power.

Description

technical field [0001] The invention relates to the technical field of cabinets, in particular to a vertical temperature uniform IT cabinet. Background technique [0002] For database server cabinets at home and abroad, no matter what method is used to obtain cooling capacity to cool down the server, there is a problem that the temperature difference between the top and bottom of the cabinet is too large. The temperature difference is 4-6 degrees, and even a temperature difference of more than 10 degrees is common. This is a result of the cabinet design not being well linked to the air conditioning system. This situation affects the running quality of the server, and even causes failure and damage of the server. [0003] With the advancement and rapid development of IT technology, high-density, high-power (high-heat) servers adopt cabinets with an integral structure of evaporating coils in the refrigeration system or chilled water coils prepared by air-conditioning units. ...
