多通道介质错流换热的设备冷却方法
By constructing a flow-wall temperature response adjoint matrix and real-time temperature acquisition, combined with flow boundary constraints, precise flow distribution and directional matching of cooling capacity are achieved in multi-channel cross-flow heat exchange equipment. This solves the problems of inaccurate flow distribution and thermal coupling effects in existing technologies, and improves cooling effect and equipment reliability.

Abstract
本发明公开了多通道介质错流换热的设备冷却方法，属于换热设备冷却控制领域，本方法预构建多通道错流换热设备的流量‑壁温响应伴随矩阵，同步预定义单换热通道流量物理边界约束；通过稀疏测温阵列采集壁面温度分布数据，计算温度偏差向量并代入伴随矩阵，反演得到各单换热通道实时流量分布；以管程总流量恒定为硬约束，基于壁温数据与实时流量分布生成预设通道分组的节流阀开度调节指令，重构流量分配实现冷量定向匹配，消除局部热点，实现反演单通道流量，大幅提升冷却均匀性与设备运行可靠性。
