In some embodiments, the runner structure 1 is further provided with a matched liquid inlet runner 21 and a matched liquid outlet runner 3 when in use, the liquid inlet runner 21 and the liquid outlet runner 3 can be used for communicating with a cooling liquid supply system, at this time, the starting end of the first runner 11 is communicated with the liquid inlet runner 21, and the output end of the output runner 14 is communicated with the liquid outlet runner 3, so that a circulating cooling liquid supply loop is formed.
In some embodiments, the liquid inlet channel 21 and the liquid outlet channel 3 are parallel to each other, and a plurality of channel structures 1 are parallel to each other between the liquid inlet channel 21 and the liquid outlet channel 3. As an example of one of the applications, as shown in fig. 1, four of the flow channel structures 1 are provided between the liquid inlet flow channel 21 and the liquid outlet flow channel 3.
By arranging a plurality of flow channel structures 1 between the liquid inlet flow channel 21 and the liquid outlet flow channel 3, the cooling heat exchange area between the flow channel structures 1 and external heating components can be increased, and the total length of the formed flow channel structures 1 can be conveniently controlled; for example, the length of each formed flow channel structure 1 is uniform, and compared with the form of a single flow channel structure in the conventional technology, the design length of the flow channel structure can be effectively reduced, so that the influence caused by the temperature rise along the path due to the overlong design length of the flow channel structure is reduced.
In some embodiments, the start end of the first flow channel 11 is communicated with the liquid inlet flow channel 21, and the other end of the first flow channel 11 is extended along the first direction; here, the first direction may be a direction from the liquid inlet channel 21 toward the liquid outlet channel 3.
In some embodiments, the start end of the second flow channel 12 is communicated with the extension end of the first flow channel 11, and the other end of the second flow channel 12 is arranged in an extension manner along the second direction; here, the first direction is opposite to the second direction, so that the first flow channel 11 and the second flow channel 12 are arranged in parallel, which can facilitate the thermal interaction operation between the cooling liquid in the first flow channel 11 and the cooling liquid in the second flow channel 12.
In some embodiments, the start end of the third flow channel 13 is communicated with the extending end of the second flow channel 12, and the other end of the third flow channel 13 extends towards the first direction; at this time, a concave region is formed between the third flow passage 13 and the second flow passage 12.

For example, the connection between the third flow channel 13 and the output flow channel 14 is disposed near the liquid outlet flow channel 3, so that thermal interaction can be formed between the connection between the third flow channel 13 and the output flow channel 14 and the liquid outlet flow channel 3, and further the heat exchange cooling effect is improved.
In some embodiments, along the flowing direction of the cooling liquid in the liquid outlet channel 3, the connection between the third flow channel 13 and the output flow channel 14 is located in front of the connection between the first flow channel 11 and the second flow channel 12, that is, closer to the output end of the cooling liquid, so that the heat exchange effect at different sections can be better considered, and the temperature uniformity can be improved.
As an application example, a thermal interaction is formed between the connection between the second flow channel 12 and the third flow channel 13 and the liquid inlet flow channel 21. For example, the connection between the second flow channel 12 and the third flow channel 13 is disposed near the liquid inlet flow channel 21, so that thermal interaction can be formed between the connection between the second flow channel 12 and the third flow channel 13 and the liquid inlet flow channel 21, thereby improving the heat exchange and cooling effects and being convenient for improving the temperature uniformity of the whole flow channel structure 1 in application.
