摘　　要：根据核主泵滑油冷却器的设计要求,研发了一种换热性能和流体阻力均满足要求的泡状板式滑油冷却器.采用泡状换热板增强换热效果并减小流体阻力.通过设计计算、强度计算和抗震分析对滑油冷却器进行了理论验证.理论计算得到的冷却水出口温度为44.67℃,滑油的压降为0.07MPa,冷却水的压降为0.015MPa,换热功率为67.76kW.模态分析得到的频率均大于规定的50Hz.在3种工况载荷组合下,分别对0/A,B和D等级进行了应力计算,表明薄膜应力和薄膜+弯曲应力的计算值在规定的应力限值内满足ASME规范要求.计算结果表明设计的滑油冷却器满足设计要求且安全可靠性高.同时,对滑油冷却器的传热性能和流体阻力进行了试验测试,各项结果符合设计条件,且放热量与吸热量的热平衡误差为1.83%,符合热平衡的试验要求.针对滑油冷却器的设计提出的新思路,可以为板式滑油冷却器的改进与优化提供借鉴.According to the requirement of the oil cooler of rector coolant pump(RCP),a bubble-plate type oil cooler,which met the requirements of both heat transfer performance and fluid resistance was developed.The heat transfer effect was increased and the fluid resistance was reduced by using the bubble type heat exchanger plate.Through the design calculation,strength calculation and seismic analysis,the theoretical verification of the oil cooler was carried out.Through the theoretical calculation,the cooling water outlet temperature was 44.67℃,the oil pressure drop was 0.07 MPa,the cooling water pressure drop was 0.015 MPa,and the heat exchange power was 67.76 kW.The frequencies obtained by modal analysis were greater than the specified 50 Hz.Stress calculations were carried out for the 0/A,B and D grades under the three load combinations,indicating that the calculated values of film stress and film+bending stress were within the specified stress limits and met ASME specifications.The calculation results show that the designed oil cooler meets the design requirements and has high safety and reliability.At the same time,the heat transfer performance and fluid resistance of the oil cooler were tested.The results meet the design conditions,and the thermal balance error of heat release and heat absorption is 1.83%,which meets the experimental requirements of heat balance.It presents a new idea for the design of the oil cooler and provides reference for the improvement and optimization of the plate type oil cooler.
