Abstract
Description
technical field
[0001] The invention relates to the technical field of PLC control boxes, in particular to a PLC control box with good heat dissipation and dehumidification performance. Background technique
[0002] The full English name of PLC is Programmable Logic Controller, an electronic system operated by digital operations, designed for use in industrial environments. It uses a type of programmable memory for its internal storage program, execution of user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery through digital or analog input / output Or production process, is the core part of industrial control. However, a large amount of heat will be generated during the working process of the PLC. The current heat dissipation method generally has the problem of low heat dissipation efficiency, and long-term high temperature affects the service life of the PLC. The patent No...
