Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation device design for a CNC machining center, in particular to a high-efficiency heat dissipation device for a CNC machining center. Background Art

[0002] A CNC machining center is an automated machine tool controlled by a computer digital control. It can perform multiple machining operations, such as milling, drilling, boring, and tapping, in a single setup, with high precision and efficiency. The CNC machining center controls the movement of the machine tool through a computer program. Operators write a machining program based on the part's design drawings. The program contains information such as the tool's motion trajectory and cutting parameters (such as cutting speed, feed rate, and depth of cut). The computer converts these program instructions into electrical signals that drive the motors of the machine tool's various coordinate axes (such as the X, Y, and Z axes), thereby controlling the tool's position and movement relative to the workpiece and completing the workpiece's machining.

[0003] When the heat dissipation device blows air to cool the machining center, it needs to be equipped with a filter to prevent dust from accumulating inside the machining center. The existing device lacks a design that automatically cleans the filter after use, which can easily affect the heat dissipation effect if used for a long time. At the same time, there is no design that can also cool down the coolant after use, resulting in a large energy consumption for the entire device. Utility Model Content
