Problems solved by technology
[0003] Although the above methods can reduce the temperature rise of the heating components to a certain extent, since the temperature of the cooling circulating fluid is generally a constant value during use, or changes with the ambient temperature, it cannot be adjusted in time according to the temperature rise of the heating components. Under the control logic of the system, the cooling effect of the cooling circulating fluid cannot be maximized

The invention belongs to the field of temperature cooling control, and particularly relates to a temperature self-adaptive adjusting method of a cooling circulation loop. The real-time temperature of a cooling circulation loop in a heating part and at a liquid outlet is detected, and the real-time temperature rise of the heating part is calculated by combining the reference temperature of the heating part; calculating the real-time target temperature of the cooling circulation loop at the liquid outlet of the heating component according to the real-time temperature rise of the heating component and the initial target temperature of the cooling circulation loop at the liquid outlet of the heating component; and then the deviation between the real-time temperature of the cooling circulation loop at the liquid outlet of the heating component and the real-time target temperature is calculated, and the temperature of cooling liquid input to the heating component by the refrigerating machine is adjusted in real time according to the deviation value. The liquid supply temperature of the cooling circulation liquid can be automatically adjusted according to the temperature rise condition of a heating part, the cooling effect is good, the automatic temperature adjusting requirement of a single-path cooling circulation system can be met, and the independent temperature adjusting requirement of all branches in a multi-path cooling circulation system can be met.
Description
technical field [0001] The invention belongs to the field of temperature cooling control, in particular to a temperature self-adaptive adjustment method of a cooling cycle loop. Background technique [0002] High-precision processing equipment generally has higher requirements on the temperature of its own parts and the surrounding environment. Taking CNC machine tools as an example, during the processing of workpieces, spindles, screw screws, beams and other parts produce different degrees of heat due to frictional heat generation and heat conduction. Temperature rise, due to the thermal expansion and contraction characteristics of the material, will produce different degrees of thermal deformation, which will affect the processing accuracy. In order to reduce the temperature rise of each heating component, a cooling circulation system is usually configured in the CNC machine tool. Generally, multiple refrigeration equipment or a single refrigeration equipment are divided i...
