Such as powerful server cluster, precise and complex network switching equipment and storage capacity of huge storage array, these devices in the process of uninterrupted operation, due to the continuous power supply of internal circuit and complex signal processing and data operation, produce unceasingly and the quantity is very considerable heat.

[0003] When these heat continuously accumulates in the relatively closed space of the cabinet, if it cannot be properly handled and dispersed, the temperature inside the cabinet will rise sharply. Once the temperature exceeds the normal range that the electronic equipment can withstand, the running speed of the chip will be significantly reduced, the physical properties of the electronic components will gradually deteriorate, the stability of the equipment will be greatly discounted, and the service life will be sharply shortened. In severe cases, the device may malfunction and stop running, and then cause permanent data loss in the data center, and the communication network of the communication base station is paralyzed, and other serious consequences are difficult to recover.

[0004] However, the traditional cabinet temperature control mode often has problems such as low temperature control efficiency, uneven temperature distribution, high energy consumption, and inability to achieve uniform temperature regulation of the entire cabinet space, which is difficult to meet the growing demand for cabinet heat dissipation; and the existing temperature control device is not easy to disassemble and replace, when a component fails, the entire temperature control device needs to be disassembled and debugged on a large scale, or even the entire temperature control device needs to be replaced, which not only reduces its work efficiency, increases the maintenance time and workload, but also greatly increases its maintenance cost.

[0075] Embodiment 2

[0076] As shown in Figure 2 , Figure 4 , the power supply 26 further includes a power supply interface 261; the power supply interface 261 is arranged on the temperature control box 21, and the power supply interface 261 is arranged on the outer surface of the cabinet 212;

[0080] The temperature sensor 23 is connected with the sensor input end 5 of the temperature control board 24 at one end, and is connected with the sensor input end 6 of the temperature control board 24 at the other end. The zero line end of the power interface 261 is directly connected with the power input end of the temperature control board 24, and the live wire end is connected with the power input end of the temperature control board 24 through the temperature control switch 25, so that the power supply of the temperature control board 24 is effectively controlled by the temperature control switch 25. Under normal circumstances, the temperature control switch 25 is closed, the power supply successfully supplies power to the temperature control board 24, and the normal operation of the temperature control board 24 is ensured to monitor and control the temperature. When the temperature is abnormal, the temperature control switch 25 can act according to the preset condition to cut off or restore the power supply to the temperature control board 24, so as to realize accurate control of the whole temperature control process, prevent system failure or out of control caused by abnormal power supply, and ensure the reliability of the temperature control system.

[0082] The connection of the temperature sensor 23 and the sensor input end of the temperature control board 24 ensures that the temperature information can be transmitted to the temperature control board 24 in time and accurately. The temperature sensor 23 can monitor the temperature change in the cabinet 1 in real time, and convert the change into an electrical signal to transmit to the temperature control board 24. After receiving the temperature signal, the temperature control board 24 can quickly analyze and process it, and decide whether to start the heat dissipation fan 22, adjust the fan speed or perform other temperature control operations according to the preset temperature control strategy. The accurate temperature monitoring and transmission mechanism enables the temperature control system to quickly respond to temperature changes, so that the temperature in the cabinet 1 is always maintained within a suitable range, effectively ensuring the normal operation environment of the electronic equipment, and avoiding the adverse effects of high or low temperature on the performance and service life of the equipment.
