Description

High-precision and high-safety integral modular design constant temperature and energy-saving server cabinet

technical field

The utility model relates to a cabinet, in particular to a constant temperature and energy-saving server cabinet with high precision, high safety and overall modular design, which has reasonable structure, scientific layout, low temperature and dry environment, safety and energy saving. the

Background technique

The existing constant temperature and energy-saving server cabinets generally have the following defects:

1. Due to volume limitations, a standard server cabinet cannot be installed with a cooling device with a large cooling capacity and output power, so it cannot accommodate multiple servers (such as a total power of more than 3000w), which seriously affects its cost performance.

2. Due to the heat insulation requirements of the energy-saving constant temperature cabinet, the cabinet itself has a large weight, and once the server computing is running, it is strictly forbidden to be disturbed, so any fault maintenance should not affect the normal operation of the server, but the existing energy-saving The constant temperature cabinet basically refers to the principle of the air-cooled refrigerator, and the refrigeration equipment is regarded as a part of the cabinet as a whole, which cannot be moved and repaired at all, so once a refrigeration failure occurs, serious consequences will occur.

3. Because the application objects of the energy-saving constant temperature cabinets all have quiet requirements, and if the cooling and heat transfer performance is to meet the design requirements for complete cooling of the cabinet, the fan must not be less than the corresponding design air volume, and the general noise is above 60 decibels, which will interfere People work normally and cannot meet the requirement of free computer room.

4. Due to the size limitation of the standard cabinet and the installation requirements of the internal server, the design of the air duct of the energy-saving constant temperature cabinet inevitably has the consideration of bending and turning, which will lose the wind pressure and reduce the wind speed, so that the heat source in the cabinet cannot be pumped quickly. If the power of the fan is increased, the energy consumption and noise will be increased, which is contrary to the purpose of energy saving.

5. Since the fan is in a continuous working state for a long time, and the life of any fan is limited, long-term work will inevitably cause the fan to age and reduce performance. It is very important to maintain and replace it in time without affecting the normal operation of the server. , This is a problem that all energy-saving constant temperature cabinets do not consider at present.

6. Since the energy-saving constant temperature cabinet works in a relatively sealed container, the heat of the server is continuously generated. When the external ambient temperature is below 10 degrees Celsius, it is undoubtedly a non-energy-saving working condition to continue to use the internal cooling system .

For example, the patent number: 201220586028.4, the name is: a high-safety integrated constant temperature dehumidification and energy-saving server cabinet. Although the drawer-type setting of the refrigeration unit solves some of the above-mentioned problems, it can stop the compressor refrigeration when the room temperature is lower than 10 degrees. Further consideration of energy saving in work is not enough.
