Problems solved by technology

The patent No. 201720363047.3 discloses a LIC control box. Although it also has good heat dissipation performance, since the water collecting plate is set on the top during the heat dissipation process, the water on the water collecting plate is easy to drip onto the internal electronic components. On the other hand, it will cause water ingress of electronic components, which will easily lead to damage of electronic components; a PLC control box published by patent No. CN207185009U, which only uses cooling fans and cooling holes to dissipate heat, and the cooling effect is not good

Abstract

The invention discloses a PLC control box with good heat dissipation and dehumidification performance. The control box comprises a shell, and a PLC is arranged in the middle of the interior of the shell. A temperature sensor and a humidity sensor are sequentially arranged on one side of the PLC. A supporting frame is arranged at the top end in the shell. A plurality of cooling fans are arranged atthe top end of the supporting frame. A microcontroller is arranged on one side of the top end of the supporting frame. A water collecting tank is arranged at the bottom end of the interior of the shell; a drainage pipe is arranged at the bottom end of one side of the water collecting tank, a condensation pipe is arranged at the top end of the water collecting tank, a water outlet of the condensation pipe is fixedly connected with a water pump, a drainage port of the water pump is fixedly connected with a condenser through a water return pipe, and the condenser is fixedly connected with a water inlet of the condensation pipe through a water feeding pipe. The control box has the advantages of having good heat dissipation and dehumidification functions, solving the problem that the temperature in the control box is too high, and prolonging the service life of the control box.

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...
