摘要

为了提高带液冷产品可靠性强化试验的效率,针对带液冷产品的特点分别设计了通液和不通液条件下的可靠性强化试验方案,并选取典型的带液冷产品开展可靠性强化试验的应用研究。试验结果表明,在通液条件下产品内部的温度跟随性较差,加严环境温度应力难以激发产品故障;在不通液条件下产品内部的温度跟随性较好,提高环境温度应力水平可快速地激发故障,暴露产品的薄弱环节。基于上述研究结果,给出了带液冷产品可靠性强化试验方案的设计思路,以指导带液冷产品可靠性强化试验的有效实施。
        In order to improve the efficiency of the reliability enhancement test of liquid cooled products, the reliability enhancement test schemes under the conditions of liquid cooled and non-liquid cooled are designed aiming at the characteristics of liquid cooled products, and the typical liquid cooled products are selected to carry out the reliability enhancement test application research. The results show that the internal temperature following feature is poor under the liquid cooled condition, and it is difficult to excite the product failure by tightening the temperature stress, and the internal temperature following feature of the products is better under the non-liquid cooled condition, and improving the environmental temperature stress level can quickly stimulate the failure and expose the weak links of the products. Based on the above research results, the design idea of reliability enhancement test scheme for liquid cooled products is presented so as to guide the effective implementation of reliability enhancement test for liquid cooled products.
