The present invention relates to the technical field of electrical control, in particular to a control box temperature control system, the electric control box box; a manual heating switch outside the box; a low temperature resistant power relay located in the box, a power supply port, and a The PET electric heating film on the inner surface of the box, the manual heating switch is connected to the low temperature resistant power relay, and the low temperature resistant power relay is arranged between the power supply port and the PET electric heating film; , by turning on the manual heating switch, controlling the low temperature resistant power relay to close, so that the power supply port is connected to the PET electrothermal film, so that the PET electrothermal film heats the ambient temperature in the box, Furthermore, under extremely cold working conditions, when the temperature control module fails to work normally, the power supply to the PET electric heating film is turned on through the manual heating switch, so as to improve the temperature environment in the electric control box and avoid It will affect the working performance of the electric control box.
Description
technical field [0001] The invention relates to the technical field of electrical control, in particular to a control box temperature control system. Background technique [0002] At present, industrialization has been upgraded and transformed, and it has developed in the direction of intelligence, informatization, and electronic control. Electronic control components such as computer microcontrollers, data acquisition modules, and signal processing modules have been widely used in the field of construction machinery. [0003] However, due to the long and cold environment in some areas in winter, for example, the minimum temperature can reach -50 ℃, such a harsh working environment brings a severe test to the performance of construction machinery. [0004] Under normal circumstances, the working temperature tolerance range of most electronic control components of construction machinery is -40℃~+85℃. When the temperature is lower than -40℃, the working performance of electron...
