During flowing, constantly flowing into the second sprue 42 by the transverse concave groove on plate, finally, heat exchange is situated between
Matter all can flow out from the second sprue 42 and flow to the octal mouth 341 being positioned at lower exit.
In order to prevent heat transferring medium from directly not flowed at two edges by the stop of guiding device 4 at sheet edges
Be positioned at the aperture at lower exit, need guiding device 4 wave to width and the width of plate between difference
Value keeps within the specific limits, optionally, the width of plate and guiding device 4 wave to width between
The half of difference is less than the width of U-shaped sprue on guiding device 4, more optionally, the width of plate and water conservancy diversion
Device 4 wave to width between the half of difference less than the width of the transverse concave groove of heat transfer zone on plate.
Here can have two kinds of set-up modes, a kind of be directly by the limit of U-shaped sprue near the limit of heat exchange plate
At edge, another kind is to retain the first epitaxy part 43 He extended outward on the both ends of guiding device 4
Second epitaxy part 44, it is preferred that in order to improve the heat exchange efficiency at sheet edges position, present embodiment uses
The first epitaxy part 43 and the second epitaxy part 44 extended outward is retained on two ends of guiding device 4.
So, at sheet edges, limit along the sprue heat transferring medium that flows downward directly can carry out heat by plate
Exchange.And directly by the limit of U-shaped sprue near heat exchange plate edge time, due to by guiding device 4
Stop, the heat exchange efficiency of edge is the highest.So outside present embodiment uses arranging on guiding device 4
