Abstract： |
The miniature pump for small fuel cell to dissipate heat has runway type circulating flow channel with viscous circular medium packed and rotor shaft set vertically inside the circulating flow channel eccentrically. The present invention is designed based on small fuel cell with the features of small inside space and enough electricity, and obtains the geometric structure of the runway type circulating flow channel via experiment and numerical calculation. The present invention has compact structure for easy installation inside small fuel cell, stable flow of heat transferring circular glycol medium in the runway type circulating flow channel to reach the heat dissipating requirement for the small fuel cell, and capacity of driving the miniature pump with the electric power inside the small fuel cell. |
