Description

M251439 V. Creation Description α) < Technical Field of New Type > This creation is related to the structural design of a cabinet, especially a cabinet suitable for providing stacked or side-by-side installation of electronic equipment such as servers, telecommunications hosts, switches, etc. -< Previous technology > In response to the rapid development of the semiconductor industry, accompanied by the popularization of the computer industry and related network services, individuals, businesses and groups have become increasingly dependent on computers and network services, especially After many business activities, computerization of transactions and networking, it has significantly improved business competitiveness, timeliness and reduced related costs. However, in the operation of these acts or transactions, if you encounter unexpected conditions such as power outages, computer crashes, network disconnections, etc., the possible losses will be difficult to estimate. Therefore, constructing a working environment that provides stable operation of electronic equipment is even more necessary to maintain the normal operation of these behaviors or transactions. Common applications such as audio and video, video, monitoring equipment, switches, servers, computers, telecommunications, and instrumentation hosts are key electronic devices for workstations. They are stacked or placed side by side in a cabinet, and then the cabinet is kept In a machine room with an air-conditioning environment such as appropriate temperature and humidity, it constitutes a working environment in which electronic equipment operates stably. Among them, it is especially important for the cooling and cooling of electronic equipment, because most of the reasons that cause electronic equipment to crash are from the overheating of components such as semiconductors and hard disks. Taking the current ® to improve the working efficiency of integrated circuits, Continually work towards increasing the frequency of semiconductor crystal density, but for every 1 ° c increase in semiconductor operating temperature, the execution speed will decrease

Page 5 M251439 V. Creative Instructions (2) If it is reduced by 0.15%, the operating efficiency of electronic equipment will be reduced. Therefore, in the case of poor heat dissipation efficiency, as the operating temperature of the electronic device increases, the phenomenon of unstable operation will inevitably occur, and the life of the electronic device will also be reduced. -At present, the widely used electronic equipment is mainly based on those regulated by the American National Standards Institute (ANSI). The structure is roughly composed of a number of motherboards with corresponding functions set in the box body (such as China's Announcement No. 5 3 4 5 7 3, 5 3 6 1 4 2 and 5 3 6 1 4 3 and other new patents have been disclosed), and an exhaust device is installed on the side of the box body to turn the working heat source (mostly derived from The semiconductor components on each motherboard are discharged to the outside. The air extraction device is usually arranged at the rear side of the box body, and the front side is provided with an air inlet to make the fan unit of the air extraction device draw in the cold air from the front side when the fan unit is running, forcibly flow through the working heat source for heat exchange from the rear side discharge. According to this structure, it can be known that the current general-standard electronic equipment has an internal active heat dissipation design, but cold air must be provided by the outside for heat exchange to effectively reduce the operating temperature and make it work stably. The source of these cold air is practical The upper part is provided by the air-conditioned environment of the computer room. The existing computer room adopts a semi-open design. The cold air required for its air-conditioning environment is continuously supplied in the pre-planned elevated floor 1 (as shown in the first figure), and the openings are reserved for the place where the cabinet 2 is placed according to the plan. 1 1 so that cold air can pass through each opening 11 and be taken by the correspondingly arranged cabinet 12. Among them, the conventional cabinet 2 is generally composed of a frame outer side plate, front and rear doors, and top and bottom plate (as disclosed in the new patent No. 2 1 2 3 4 4 in China), and is attached on both sides of the frame. Standard preset several keyholes for

M251439 V. Creative Instructions (3) Install several electronic devices stacked at intervals 3. In order to provide convenience and need for wiring, each electronic device 3 is installed as close to the front door as possible to maintain sufficient wiring space between the rear side and the rear door. The bottom sealing plate of cabinet 2 is reserved with an air inlet 2 1 corresponding to the opening 1 1, and a number of fans 2 2 are installed on the top and sealing plates to extract air from the top outward. However, the conventional cabinet 2 has the following shortcomings that need to be improved: 1. The power cables or signal cables of each electronic device 3 are collected through the air inlet 2 1 at the bottom of the cabinet 2 and the opening 1 1 of the raised floor 1 , Towards the preset trunking under the raised floor 1. In other words, the air inlet 21 of cabinet 2 is not only the only inlet for cold air, but also a necessary passage for wiring. This will seriously affect the air intake of cold air and lower the convection efficiency of cold and hot air. 2. The cold air is continuously flowing into the cabinet 2 due to the operation of the top fan 22, but the operation of the exhaust device of each electronic device 3 will also cause a pressure difference to attract the cold air, so a complicated turbulence will be generated inside the cabinet 2. Phenomenon hinders convection efficiency. 3. The cold air is not sufficiently and evenly absorbed by each electronic device 3 for heat exchange, and most of the cold air will tend to be discharged directly from the top fan 22, so for the real heating point (the semiconductor in the electronic device) Or hard disk components) ca n’t exert the expected heat exchange effect, and it is more likely to cause the electronic device 3 located in the middle and bottom zone to generate excessive heat instability or even crashes. 4. Due to the foregoing factors, the heat dissipation effect of each electronic device 3 is not good. The practical method is to provide a lower temperature air-conditioning environment in the computer room.

Page 7 M251439 V. Creative Instructions (4) The average temperature in cabinet 2 is lowered in the period (4). However, the actual effect of this method is not good, and it is obviously inconsistent with economic benefits. It also consumes more power, which is not enough. _ < New content > · In view of the unsatisfactory cooling effect in the previous cabinets, it was actually caused by the poor design of the cabinet structure.

In addition, it is appropriate that the air duct is located in a pillar adjacent to the front door of the cabinet body, so that all electronic devices are oriented adjacent to the front door, and the air inlet is front (front suction) and the air outlet is rear (back row). ) Installation method. Of course, air ducts can also be provided on both sides adjacent to the front door for backup purposes, and there can be one or more fans in the air ducts corresponding to the electronic equipment. In addition, the control unit not only provides the function of activating the corresponding fan to give the appropriate air volume in a timely manner, but also integrates functions such as fire detection, power failure detection, and access control, so that it has all-round control of the environment in which the cabinet is located. Flexible person. < Performance method > In order to make your reviewing committee understand the purpose, characteristics, and effects of this creation, we will use the following specific examples and the accompanying drawings to make a detailed description of this creation, as described later .
