Abstract
This disclosure relates to a temperature control system that may be applied to a machine tool. The system includes a cooling circulation and a controller. The cooling circulation comprises a pump, a cooler and a solenoid valve. The pump may be driven by a variable frequency motor so as to flow through the spindle of the machine tool. The cooler is serially connected with the liquid pump, and may cool the liquid coolant. The solenoid valve connects to inlet and outlet of the cooler, and may prevent the liquid coolant flows through the spindle from flowing back to the cooler. The controller is electrically connected with the variable frequency motor, the cooler and the solenoid valve. Further, the controller is connected to the machine tool to detect several parameters, so as to control the variable frequency motor, the cooler and the solenoid valve.
