技術說明

本發明揭露一種多流道磁控系統，運用於含有磁性顆粒之流體混合或將磁性物質分離，係將複數個磁場開關配置在複數個流道之周圍，藉由控制磁場開關的磁化方向以產生不均勻之局部磁場梯度，進而達到流體之混合或磁性物質分離之目的，本裝置亦可作為磁流體之流阻控制元件。並可根據磁場分佈需求以整體調控或局部控制複數個磁場開關，對多維度排列之多流道系統同時進行作業，以有效節省程序作業時間。流道之入出口可設置磁阻式感測器以檢測流體之混合程度或磁性物質分離後之殘留率。 Disclosed in the present invention is a multi-channel magnetic control system used for mixing flows containing magnetic particles or separating magnetic species. In the multi-channel magnetic control system, a plurality of magnetic field switches are allocated to surround a plurality of micro-channels, and the magnetization directions of the magnetic field switches are controlled to generate an uneven local magnetic field gradient, so as to achieve the purpose of fluid mixing or separating the magnetic species. This system can be also used as controllable flow resistance devices for magnetic fluids. Based on the demand of magnetic field distribution, overall or local control of the magnetic field switches can be executed to perform parallel processing over the multi-channel system of multi-dimensional allocation, so as to effectively save the processing time.
