Description

Dustproof cooling system of data server computer lab

Technical Field

The utility model relates to a heat dissipation system, in particular to a dustproof heat dissipation system for a data server machine room, and belongs to the technical field of machine room environment detection control.

Background

The physical environment as a computer room (computer learning room/data center) is strictly controlled and mainly divided into several aspects: namely temperature, power, floor, fire protection system. Temperature: in terms of temperature, air conditioning is generally used. The air conditioner is used to control the temperature and humidity of the data center, and the "data processing environment thermal guidelines" of the society of refrigeration and air conditioning engineering recommends a temperature range of 20-25 ℃ (68-75 ° f), a humidity range of 40-55%, and a maximum dew point temperature suitable for the data center environment of 17 ℃. In data centers, power supplies heat air and unless heat is removed, the ambient temperature rises, causing the electronics to malfunction. By controlling the air temperature, the server assembly is able to maintain the manufacturer specified temperature/humidity range. Air conditioning systems help control humidity by cooling the indoor air down to the dew point, which is too great and water may begin to condense on internal components. If in a dry environment, the auxiliary humidification system may add water vapor, as if the humidity is too low, electrostatic discharge problems may result, possibly damaging components. Power supply: the power supply of the machine room is a standby power supply consisting of one or more Uninterruptible Power Supplies (UPS) and/or diesel generators. To avoid a single point of failure, all power systems, including the backup power supply, are fully redundant. For critical servers, two power supplies are connected simultaneously to achieve the reliability of an N +1 redundant system. Static switches are sometimes used to ensure instantaneous switching from one power source to another in the event of a power failure. Floor board: the floor of the machine room is raised by 60 cm (2 feet) with respect to the tile floor, which is 80-100 cm as the society grows, to provide better even distribution of air flow. Air conditioning systems thus allow cool air to be also poured under the floor while also providing more ample space for underground power line wiring, and data cables in modern data centers are typically routed through overhead cable trays, but some have suggested that data lines should be routed under the floor for safety and to allow for the addition of cooling systems. Static-free floors may not be used in small data centers without raised floors. Computer cabinets are often organized into a hot aisle to maximize air circulation efficiency. A fire protection system: the fire protection system of the machine room includes passive and active designs, as well as fire protection action execution plans. A smoke detector is usually installed, a fire alarm can be found in advance before open fire is generated by combustion, a power supply can be cut off before the fire is increased, and a fire extinguisher is used for manually extinguishing fire. Automatic water-spraying fire extinguishing devices cannot be used in data centers because electronic components often fail after encountering water, and the situation of using water to extinguish a fire becomes worse especially in the case of power supply non-cutoff. Even if an automatic sprinkler system is installed, the clean gas fire suppression system should be started earlier than the automatic sprinkler system. A firewall should be installed in the data center so that the fire source can be controlled to a local area, and even if a fire breaks out, the loss can be minimized. Due to the particularity of the machine room, the heat dissipation of the machine room can only be realized by air cooling, but cannot be realized by water cooling; however, a large amount of dust is introduced into the electronic component due to air cooling, and if the dust cannot be cleared in time, the normal operation of the electronic component is affected; the existing machine room cannot accurately detect the dust content; dust removal can not be carried out according to actual conditions. Therefore, further improvements are awaited.
