This invention discloses a heat-exchange fluid allocation headplate and inducer connecting to it which includes a fluid inlet section and an arc head plate connecting section, adding an arc connector or an isolation board as the secondary head plate in between, many through holes are distributed on the isolation board. The induced angle of the inducer is set to be 45 deg. diameter of hole on it is 2 mm. A liquid adding cavity is designed at the edge the ratio of its width to that of the head plate opener is 0.2. It's the first time to put out the concept of two times of head plate and introduce structure of unniformly slotted orifice plate. This invented inducer structure reduces flow rate of maximum and minimum on unit internal channel vertical direction to 2-5 times from 3-7. |
