Problems solved by technology

In the common machine tool cooler system, it is generally only adjusted by the frequency conversion compressor and the electronic expansion valve, so the adjustment accuracy is not high, generally ±0.5°C
[0006] 2. The cooling capacity adjustment range is small
Since the operating range of the variable frequency compressor is certain, if the load changes greatly, there may be a problem that the compressor drops to the minimum frequency, and the cooling capacity is still greater than the heat load, which eventually leads to the problem of low coolant temperature

Abstract

The invention discloses a cooling system and a cooling control method and relates to the field of cooling control. The cooling system comprises a cooling branch and a bypass branch, wherein a cooling device is arranged on the cooling branch and the two ends of the bypass branch are respectively communicated with an inlet and an outlet of the cooling device, so that the cooling liquid flowing out of the bypass branch can be mixed with the cooling liquid flowing out of the cooling device. According to the invention, the bypass branch is additionally arranged in the cooling branch, so that the cooled cooling liquid can be mixed with the uncooled cooling liquid. Thus, the temperature adjustable range can be effectively expanded and the control precision can be increased.

Description

technical field [0001] The invention relates to the field of cooling control, in particular to a cooling system and a cooling control method. Background technique [0002] In modern manufacturing, machine tools are indispensable equipment, such as CNC (Computer Numerical Control, digital control machine tools), grinding machines, wire cutting machine tools and so on. When the machine tool is working, the high-speed operation of the cutting tool and the spindle will generate a lot of heat, which will cause thermal deformation of the guide rail and the spindle of the machine tool, thereby reducing the machining accuracy of the workpiece and reducing the life of the tool and the spindle. Therefore, there is a need to cool the machine tool. The role of machine tool coolers such as oil coolers (also known as oil coolers) is to effectively reduce the heat generated by machine tool cutting and improve the machining accuracy of machine tools. [0003] The current machine tool cool...
