Abstract

The invention discloses a hub temperature detecting and cooling control system, and relates to the field of temperature control of automobiles. The problems that in the prior art, the temperature measurement response is slow and the error is large are solved. The system comprises a control terminal, a water tank, water spraying electromagnetic valves and infrared temperature probes arranged on hubs. Corresponding water conveying pipes are arranged between the water tank and all the hubs. The water spraying electromagnetic valves used for controlling the water conveying pipes to be opened and closed are arranged in the water conveying pipes respectively. A heater is arranged in the water tank. The heater and the water spraying electromagnetic valves are all connected with the control terminal. The infrared temperature probes are used for collecting temperatures of the hubs and uploading the temperatures to the control terminal where the upper temperature limit value is set. When the temperatures of the hubs are detected to be too high, the control terminal controls the water spraying electromagnetic valves to be opened, and water in the water tank is sprayed onto the hubs through the water conveying pipes to cool the hubs. When the temperatures of the hubs are lowered to a certain value, the water spraying electromagnetic valves are closed. The hub temperature detecting and cooling control system is high in accuracy, low in power consumption and good in stability, the temperatures of the hubs can be collected to the control terminal to be displayed in real time, and the hubs can be cooled in a dynamic equilibrium manner.
