Abstract

The invention discloses a PLC with a good heat dissipation performance. The PLC comprises a mounting base; a shell is arranged on the mounting base; a cover plate is arranged at the top of the shell;a storage cavity is formed outside the shell; an opening is formed in one side of the storage cavity; a push rod is arranged at the opening in a penetrating manner; a mounting groove is formed in thepush rod; and a control panel is placed in the mounting groove; a containing groove is formed in the shell, a control device is arranged on the containing groove, a first motor and a temperature sensor are fixedly arranged at the top in the shell, the first motor is electrically connected with the temperature sensor and the control device, the output end of the first motor is connected with a rotating shaft, and a cooling fan is installed at the bottom of the rotating shaft. The PLC has the beneficial effects that the temperature sensor is arranged to detect the temperature in the shell, whenthe temperature is too high, the control device can control the first motor to work to drive the rotating shaft to rotate, and the rotating shaft rotates to drive the cooling fan to rotate to dissipate heat in time.

Description

technical field [0001] The invention relates to the field of PLC control, in particular to a PLC controller with good heat dissipation performance. Background technique [0002] The PLC control system is a new generation of industrial control devices formed by introducing microelectronics technology, computer technology, automatic control technology and communication technology on the basis of traditional sequence controllers. The purpose is to replace relays, execute logic, timing, Sequential control functions such as counting, to establish a flexible program-controlled system. It has the characteristics of strong versatility, convenient use, wide adaptability, high reliability, strong anti-interference ability, and simple programming. [0003] In the Chinese patent application number CN201821266339.6, a PLC controller heat dissipation mechanism for electrical components is proposed, including the main body of the PLC controller. The two ends of the main body of the PLC c...
