Abstract

The invention relates to a circuit board protecting device, in particular to a circulating liquid type self-sensing optimal temperature circuit board protecting device. The circulating liquid type self-sensing optimal temperature circuit board protecting device comprises a container containing a circuit board, the container is filled with insulating liquid in which the circuit board is immersed, a temperature sensor is arranged in the insulating liquid, the container is provided with a pipeline connected with the external loop of the insulating liquid, and the pipeline is provided with a circulating power device and a temperature adjusting device; the temperature sensor, the circulating power device and the temperature adjusting device are electrically connected with a controller; a plurality of container liquid flow pipelines can be connected in series or in parallel; multiple circulating power devices and multiple temperature adjusting devices can be connected in series or in parallel to be used according to needs. By the adoption of the circulating liquid type self-sensing optimal temperature circuit board protecting device with the technical scheme, the circuit board has the advantages of preventing high temperature, freezing, moisture, dust, electromagnetism and explosion, extinguishing arcs and being resistant to pressure in deep water.

Description

technical field [0001] The invention relates to a circuit board protection device, in particular to a circulating fluid type self-sensing temperature-adaptive circuit board protection device. Background technique [0002] Electrical equipment is widely used in different living and industrial environments. As an important equipment in electrical equipment, circuit boards face various harsh environments. Under realistic conditions, such as chemical, vibration, high dust, salt spray, humidity, electromagnetic Corrosion, softening, deformation, mildew and other problems may occur on the circuit board in high temperature and other environments, resulting in circuit failure of the circuit board, so it is particularly important to protect it in various environments such as indoors or outdoors, dry or humid. [0003] The existing protection technology is mainly to apply conformal paint to the solder joints of electronic components on the circuit board, then place the circuit board ...
