煤矿发生事故时矿井透地通信系统将发挥巨大作用,隔爆型透地通信主机散热性能的好坏直接决定系统工作性能。基于热管技术完成了隔爆型透地通信主机散热方案设计,对热管散热结构热阻进行数值计算,结果证明该散热结构能满足主机散热性能要求。采用数值仿真得到了热管散热结构的温度场云图,结果与数值计算十分吻合。根据设计方案加工出样机,通过实物温度监测验证了设计的正确性,表明该热管散热结构能满足设计要求。
Mine coal mine accident communication system will play a huge role in communication, explosion-proof through-ground communication host cooling performance directly determines the system performance. Based on the heat pipe technology, the design of the flameproof through-ground communication host cooling scheme is completed, and the thermal resistance of the heat pipe cooling structure is numerically calculated. The results show that the cooling structure can meet the requirements of the host cooling performance. The temperature field of heat pipe cooling structure is obtained by numerical simulation. The result is in good agreement with the numerical calculation. The prototype was processed according to the design scheme, and the correctness of the design was verified through physical temperature monitoring, indicating that the heat pipe cooling structure can meet the design requirements.
