Machine cooling system for original machine

Abstract

An improved cooling system for an original machine comprised of a temperature controller, a linear temperature sensor, a cooling liquid tank provided with a heat exchanger and a refrigeration frequency variable compressor; hot liquid of the original machine being detected by the sensor with data transmitted to the temperature controller for comparison with the preset temperature to control the refrigeration output of the compressor for the tank temperature to reflect as required by the original machine without causing excessive fluctuation of temperature difference, thus to achieve zero error in the positioning of the main shaft of the original machine in process.

I claim:  
     
         1 . An improved cooling system for an original machine comprised of a temperature controller, a linear temperature sensor, a cooling liquid tank provided with a heat exchanger, and a refrigeration frequency variable compressor characterized by that the temperature of the original machine detected by the linear temperature sensor being transmitted to the temperature controller to be compared with the preset value to control refrigeration capacity of the refrigeration frequency variable compressor depending on the results of the comparison for the temperature of the cooling liquid tank to faithfully reflect as demanded by the original machine; and the temperature of a main shaft in the original machine being maintained at a preset value without causing drastic fluctuation of temperature difference thus to achieve zero error of process positioning for the main shaft of the original machine.
