Abstract: A cooling system for cooling a machine tool having a machine temperature. The cooling system comprises gas source, refrigeration circulation, fan, and controller. The gas source is configured for providing gas. The refrigeration circulation comprises heat exchanger, compressor, condenser, and expansion valve. The heat exchanger is in fluid communication with the gas source and configured to cool the gas down to target temperature and to provide the gas to the machine tool. The compressor has operation frequency. The fan is configured to cool the condenser and has a rotation speed. The controller is connected to the compressor and the fan. When a target temperature difference that is equal to the machine temperature minus the target temperature is smaller than threshold temperature difference, the controller keeps the operation frequency at minimum frequency and sets the rotation speed to be smaller than a maximum rotation speed.

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.
