Embodiment 1

[0019] Embodiment one, such as figure 1 As shown, the signal machine cabinet of the present invention includes a top cover 1 and a cabinet door 2, and a main control module (not shown in the figure), an exhaust device 3 and an air suction device 4 are arranged in the cabinet, wherein the air suction device 4 is provided In the cabinet bottom plate, the suction device 4 includes two AC fans 5 connected in parallel, and the two AC fans 5 connected in parallel form a fan module, and each fan 5 is covered with a dust-proof net (not shown in the figure), and the exhaust The gas device 3 is arranged in the top cover 1 of the cabinet, which includes a similar fan module. The fan module includes two AC fans 6 connected in parallel. The specific structure is similar and will not be described here; The temperature and humidity sensors connected to the module, the temperature and humidity sensors transmit the sensed temperature and humidity signals to the main control module, and the mai...

Embodiment 2

[0020] Embodiment 2 differs from Embodiment 1 in that: the suction device 4 of this embodiment is arranged below the cabinet door 2 inside the cabinet, and of course it can also be arranged at other positions below the cabinet door. Others are the same as Embodiment 1. This is not the case. repeat.

Abstract

The invention provides a signal cabinet with a forcible exhaust air system, aiming to solve the problem, in the prior art, that the heat generated inside the cabinet can not be discharged as quickly as possible because of a one-way circulating exhaust air system in the signal cabinet. A suction device and a temperature sensor and a humidity sensor connected with a main control module are arranged inside the cabinet, the main control module receives the temperature signal and the humidity signal transmitted from the temperature sensor and the humidity sensor to control the starting-up / shutting-down of the suction device and an air exhausting device, so as to form a forcible airflow circulation system which can discharge the heat generated from the equipment inside the cabinet, such as a hardware system, an industrial controller and a power supply, out of the cabinet as quickly as possible, thereby ensure long-term stable operation of the modules inside the cabinet. The temperature sensor and the humidity sensor can keep the operating environment inside the cabinet within a specified temperature and humidity range.

Description

technical field [0001] The invention relates to a communication cabinet structure, in particular to a signal cabinet with a forced air exhaust system. Background technique [0002] At present, the third generation of signal machine products has been developed. The internal configuration of the products has been continuously improved, and the range of users has become wider and wider. Especially the development of electronic police products. Wet use environment puts forward higher requirements. [0003] Existing signaling cabinets generally have a natural circulation system without a fan, or a one-way circulation system with only an exhaust fan. The heat generated by the internal hardware system of the cabinet, industrial computer, power supply and other equipment cannot be discharged from the cabinet as soon as possible, resulting in an excessive temperature difference between the inside and outside of the cabinet. Large, generally around 20 degrees Celsius, the cabinet and...
