High temperature flow splitting component and heat exchanger and reforming means using the same

A heat exchanger, comprising:

• at least one channel plate, having a first side and a second side to be furnished respectively and opposite to each other, a plurality of entrance holes and a plurality of exit holes, the plurality of entrance holes comprising a first entrance hole and a second entrance hole located oppositely diagonally to the first entrance hole, the plurality of exit holes comprising two first exit holes and a second exit hole located oppositely diagonally to the first exit holes, a plurality of first fluid channels being provided on the first side, and a plurality of second fluid channels being provided on the second side, a first fluid being to flow respectively from the first entrance hole to the two first exit holes through the plurality of first fluid channels, and a second fluid being to flow respectively from the second entrance hole to the second exit hole through the plurality of second fluid channels, the first fluid and the second fluid having different temperatures,
• wherein the plurality of first fluid channels are formed by a plurality of high-temperature flow-splitting components, and each of the plurality of high-temperature flow-splitting components comprises:
• a single entrance channel, used for introducing the first fluid at a total flow rate, wherein the entrance channel has an exit;
• a single primary channel, connected with the entrance channel, forming a first angle with the entrance channel, the first angle ranging from 90°˜270°, wherein the primary channel has an entrance directly connected with the exit of the entrance channel, such that the first fluid completely flows into the primary channel from the entrance channel;
• and
• a single subordinate channel, connected with the primary channel, forming a second angle with the primary channel, the second angle ranging from 30°˜150°, the subordinate channel has an entrance directly connected with the primary channel and not directly connected with the exit of the entrance channel, such that the first fluid in the primary channel flows distributedly into the subordinate channel and downstream in the primary channel;
• wherein at the entrance of the subordinate channel, the first fluid flowing downstream in the primary channel has a first flow rate, the first fluid flowing into the subordinate channel has a second flow rate, and a sum of the first flow rate and the second flow rate is equal to the total flow rate;
• wherein the entrance channel, the primary channel and the subordinate channel have different diameter sizes, the entrance channel, the primary channel and the subordinate channel collectively form an asymmetrical bifurcated structure with the different diameter sizes of the entrance channel, the primary channel and the subordinate channel, thereby providing different flow resistances for the entrance channel, the primary channel and the subordinate channel to obtain a specific flow-splitting performance, and controlling the flow resistances of the first fluid at different temperatures, such that a split percentage of each of the plurality of high-temperature flow-splitting components is controllable.
