[0002] Grinding fluid is a mixture of multiple ingredients. It is usually made by stirring solid particles (such as abrasives) into a liquid (such as water or oil). These solid particles are not dissolved in the liquid and are dispersed, forming an uneven, heterogeneous mixture. When the mixture stops oscillating, the particles in it will settle down. In the precision machining process of metals, ceramics and other materials, the grinding fluid plays an important role in lubrication, cooling, cleaning and auxiliary cutting. However, the temperature of the grinding fluid will rise due to frictional heat generation, which will not only affect the grinding efficiency and quality, but may also cause thermal damage to the workpiece surface and accelerate the wear of the grinding tool. Therefore, a heat sink is needed to dissipate the heat of the grinding fluid.
