The heat exchanger comprises a plurality of heat exchange units which are connected in series, each heat exchange unit comprises a hollow shell, a flow channel is arranged in the shell, a plurality of liquid cooling pipes are arranged in the flow channel, and an inlet used for receiving heat exchange liquid and an outlet used for discharging the heat exchange liquid are formed in the outer portion of the shell. And the inlets and the outlets of the adjacent heat exchange units are communicated.

This invention relates to the field of micro-power generation technology, and more particularly to an integrated micro permanent magnet direct-drive generator. The generator includes: a duct housing, a turbine, a permanent magnet power generation unit, a flow field monitoring module, and a control unit. This invention designs the inner wall of the duct as a composite curved surface with a specific helical waveform and axial contraction, precisely matching its key shape parameters with the aerodynamic design point of the turbine. This allows the airflow to be accelerated by the Venturi effect as it passes through the duct, and further endowed with tangential momentum consistent with the turbine's rotation direction by a controllable helical bulge structure. Simultaneously, based on real-time monitoring of the outlet swirl intensity and load closed-loop control, the optimal aerodynamic matching state is dynamically maintained. Furthermore, monitoring of characteristic pressure distribution enables early warning of duct performance degradation, effectively solving the problem of reduced power generation efficiency caused by mutual interference of airflows due to the use of multiple parallel independent flow guiding mechanisms.
