Meanwhile, the temperature sensing device is in signal connection with the air inducing device 12 to control the opening or closing of the air inducing device 12.
Compared with the prior art, the plenum box 11 in the exemplary embodiment can effectively and uniformly distribute the air volume, thereby ensuring that the top of the server cabinet 2 has sufficient cold air for cooling. In addition, when the number of the air supply openings is small, the static pressure box 11 can also function as a universal joint, and a plurality of static pressure boxes 11 are communicated with each other and share the same air supply opening. Meanwhile, the static pressure box 11 can effectively reduce airflow noise generated by the air supply outlet. Therefore, the cold air supplement device 1 has simple structure and convenient installation, and can obviously improve the cooling capacity without changing the structure of the existing underground air supply system machine room with great expense and week stamp, and save the cost. Meanwhile, the floor space is small, the machine room is very suitable for the narrow and compact space, can be flexibly arranged according to requirements, and is high in operability. And the setting of temperature-sensing device has then further liberated workman's both hands, makes this cold wind supplement equipment 1 can be according to the real-time temperature of server rack 2, judges whether to open or close induced air device 12, and degree of automation is high not only, and its reasonable closed induced air device 12 has still avoided unnecessary cooling operation, and the energy consumption that has significantly reduced practices thrift the resource.
In some embodiments, the temperature sensing device includes a sensor and a processor in signal connection with each other, wherein the processor is in signal connection with the air inducing device 12, and is preset with a standard temperature value for comparison, the sensor is used for acquiring real-time temperature data of the server cabinet 2, and transmitting the acquired real-time temperature data to the processor for comparison with the standard temperature value, and finally the processor controls the on/off of the air inducing device 12 according to a comparison result. Specifically, when the real-time temperature data is greater than the standard temperature value, the processor controls the air inducing device 12 to start; and when the real-time temperature data is smaller than the standard temperature value, the processor controls the air inducing device 12 to be closed.
Compared with the prior art, the sensor of the temperature sensing device of this embodiment can real time monitoring server cabinet 2's temperature current situation to send it to the treater and compare, with judge whether should start induced air device 12 and strengthen the cooling effect, consequently this embodiment need not artifical detection regulation and control, and the sensitivity is strong, always can cool down the operation to server cabinet 2 the very first time, guarantees the normal operating of server. Meanwhile, the temperature sensing device is simple in structure, the main components are the sensor and the processor, other complex and precise parts are not assembled, the manufacturing cost is low, the fault rate is low, and even if a fault occurs, the simplified structure is convenient for maintenance personnel to find out the fault reason and carry out maintenance work. In addition, the standard temperature value used for comparison in the processor can be set by self to meet the requirements of different conditions.
As shown in fig. 1, in some embodiments, the sensor of the temperature sensing device is preferably a thermistor temperature sensor 13, and the thermistor temperature sensor 13 is mounted on the server cabinet 2 for temperature monitoring during use. The thermistor temperature sensor 13 is small in size, convenient to install, very high in sensitivity, and extremely fast in response to temperature changes. Meanwhile, the temperature monitoring device has the advantages of low manufacturing cost, stable performance and high consistency between products of the same model, so that the maintenance and replacement cost is low, the problem of large monitoring result error after replacement is not easy to cause, and the quality of temperature monitoring is effectively ensured.
As shown in fig. 2, in some embodiments, the sensor of the temperature sensing device is preferably an infrared temperature sensor 14, and the infrared temperature sensor 14 measures temperature in a non-contact manner, and is therefore mounted on the static pressure box 11 and arranged relative to the server cabinet 2. The temperature measuring range is wide, and the temperature monitoring requirements of most server cabinets 2 on the market are basically met. Since it is non-contact, the infrared temperature sensor 14 has a long life and a very reliable performance. Meanwhile, the infrared temperature sensor 14 judges the temperature value through the infrared radiation emitted by the server cabinet 2, and has high precision and quick response. This cold wind of workman installation supplyes equipment 1 also more simply, only need with it move to near the server rack 2 that needs the cooling can, need not to install temperature sensor again, avoid because the flaw appears in temperature sensor's installation, and influence temperature monitoring's precision.
In some embodiments, as shown in fig. 3, the air inducing device 12 is a fan 121, and the fan 121 is aligned with the air outlet of the underground air supply system when in use, wherein a power switch of the fan 121 is connected with the processor, and when the fan 121 is started, the cold air blown out from the air outlet below the static pressure box 11 is sucked and conveyed upwards. Meanwhile, in some embodiments, the air inducing device is preferably a negative pressure fan with stronger air drafting capacity, and the on-off is controlled by a power switch connected with the processor.
As shown in fig. 2, in an exemplary embodiment, the air outlet 111 is disposed with respect to the server cabinet 2, and a louver 112 is installed to control the size and the wind direction of the air outlet 111. In the exemplary embodiment, the plenum box 11 is an air outlet 111 across the side facing the server rack 2, so that the air outlet 111 can uniformly cool the entire server rack 2. However, as is well known, since the heat generation of the servers is not uniform, and each server has its own specific heat generation point, only the louver 112 corresponding to the heat generation point of the server may be opened to concentrate the wind force to reduce the heat. Of course, the louvers 112 may be fully opened for overall heat reduction purposes, as desired, and therefore in some embodiments it may be preferable to make the height of the louvers 112 the same as the server cabinet 2.
