And the cooling device of the nut and the cooling rail of the cooling linear module and the cooling device of the slider, which can greatly improve the cooling effect of the cooling device. [Prior Art] >, the ball screw is mainly transmitted by a nut The free-rolling ball is screwed with the screw shaft, and the free-rolling ball is used to make the nut and the screw shaft move relative to each other. Due to its excellent smoothness and precision, it is widely used for various precise movements. On the machine, such as various types of micro-machining or semiconductor processing equipment, and the most λ of the existing ball screw is that the nut and the screw shaft are mainly achieved by the continuous rolling of the balls, and the idle speed Friction, the nut and the screw shaft are very prone to high temperatures, so if it is not effective cooling and cooling, long-term high temperature will cause the ball The phenomenon that the rod changes the gap due to the high temperature, and affects the accuracy of the movement, which also causes damage to the components, increases the failure rate, and invisibly increases the maintenance cost of the ball screw', and even shortens the service life of the ball screw. Effectively reducing the high temperature of the ball screw due to friction, the industry has developed a variety of different cooling designs, but the cooling effect cannot be effectively manifested due to the structural design. For example, Japanese Patent No. 63-1956 is provided with a cold portion around the periphery of the nut. According to the % path, and the nut seat is also provided with a cooling path that communicates with each other, so that the cold material 129 (4) of the 1292282 is made into a cold reliance ring, so that the circulation path is cumbersome and must be processed and cooled on the nut seat. The circulation path relatively increases the difficulty and cost of processing' and its cooling liquid convection effect is not good, so the cooling is less uniform, which directly affects the cooling effect. Another example is the Japanese patent special opening + 丨卜 (4) is the nut The front end is equipped with a cooling device, which is a kind of convection using air convection to achieve the purpose of cooling 'but the air is collected at both ends of the nut The method, the heat source that can be taken away is effective, directly affects the cooling effect, and it can not penetrate into the inside of the nut, which is easy to cause uneven cooling, and is necessary for further improvement. Moreover, as Japanese Patent No. 3721264, The utility model is provided with a cooling passage on the screw shaft, the nut and the motor seat, and is designed as a circulating cooling circuit, and is cooled and exchanged by the coolant temperature adjusting device to achieve the cooling effect, but the cooling liquid is used. Cooling down, once the sealing structure fails, it will cause the overflow of the coolant, which will cause environmental pollution. In other words, if a simple structure can be adopted and the cooling unit is deep inside the nut, and if other cooling sources can be used, The above problems can be avoided, and the cooling effect can be further improved. The reason is that the inventors have set up a discussion on the problems and needs faced by the aforementioned conventional ball screw during cooling, and have been engaged in research and development and manufacture of related industries for many years. Experience actively seeks solutions, and after long-term research and development, it has finally succeeded in development. A forced cooling of the ball screw nut 1,298,282 refrigeration apparatus, so as to overcome the poor cooling effect and the cooling fluid leak problems.
