High-speed stainless steel bearing special circulating cooling heat sink
By setting up a heat dissipation unit, an inner ring heat conduction module, and a heat transfer module on the outer side of the bearing outer ring, and utilizing a combination of cooling medium, heat transfer oil, and phase change working fluid ethanol, the problems of inner medium intrusion and high outer thermal resistance in the cooling and heat dissipation of high-speed stainless steel bearings are solved. This achieves uniform cooling and recycling of lubricating oil, thereby improving heat dissipation efficiency.

Abstract
本发明涉及轴承冷却技术领域，且公开了一种高速不锈钢轴承专用循环冷却散热装置，该高速不锈钢轴承专用循环冷却散热装置，包括轴承外圈，还包括轴承内圈、若干滚珠、基座与散热单元。该高速不锈钢轴承专用循环冷却散热装置，通过设置循环散热模块，在轴承外圈外侧形成独立的环形冷却介质流路，冷却介质经进水管进入双环管后，沿两个流动方向相反的环形管同时流动，使换热环整体温度趋于均匀，避免了单向流动带来的进口端与出口端温差过大的问题，同时，轴承外圈内壁开设的换热腔中填充导热油，导热油吸收轴承外圈内壁及附近区域的热量后，与换热环进行间接换热，再由双环管中的冷却介质带走。
