Description

technical field [0001] The present invention relates to a mechanical device, system and method in the field of electronics or communication, and in particular to a temperature control device, processing device, system and method for a cabinet. Background technique [0002] Electrical equipment such as communications, electronics or electricity are more and more commonly installed outdoors in places without climate protection and temperature regulation. Compared with the indoor environment, the changes in the outdoor environment are much more complicated. The outdoor environment is generally defined as an environment without climate protection, that is, a place without climate protection and temperature regulation, such as: open-air environment, simple computer room environment, etc. If electrical equipment such as communications, electronics, or electricity is exposed to work in a complex outdoor environment, it is easily affected by dust, temperature, and humidity changes i...

Problems solved by technology

[0031] However, the existing control schemes have the following disadvantages: first, the simple use of valves to control the ventilation volume of the equipment cannot accurately control the ventilation volume of the equipment, so that the mixing ratio of the internal air and the external air of the equipment cannot be controlled, thus The stability of the system is not high, and the performance of the system is prone to fluctuations during use

Third, the humidity sensor is a well-known easy-to-break device, and in practical applications, the relative humidity value obtained from the humidity sensor is likely to have a large error relative to the actual relative humidity value, which may lead to an increase in time and money. To increase the maintenance of the humidity sensor

Fourth, because this solution needs to collect and control two parameters of relative humidity and temperature, which increases the complexity of the system and reduces the reliability of the system

Fifth, the mixed air duct involved in this scheme is set inside the equipment, and the direct ventilation control module is not universal. Therefore, for different equipment in practice, special supporting ventilation equipment is required to meet the requirements, so this scheme does not have Modularization and generalization required for practical applications

[0033] The disadvantage of the above technical solution is that: because the dust will enter the cabinet with the flowing air and accumulate on the equipment, causing corrosion, short circuit and other failures of the equipment

Even if the dust-proof net is used, the cleaning and maintenance of the dust-proof net are frequent, which increases operating costs;

[0037] 2. In order to meet the operating temperature requirements of the equipment in a low temperature environment, it is necessary to use a heater for auxiliary heating, which consumes electric energy and increases operating costs;

Therefore, when an AC power failure occurs in a low-temperature environment, the cabinet cannot guarantee a good temperature and relative humidity environment inside the cabinet. This problem is particularly prominent in areas where the power grid is unstable.
