Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
Examples
As shown in fig. 1-4, a friction stir welding cold plate structure comprises a runner plate 1, wherein a flat plate 2 fixedly connected with the runner plate 1 is arranged at the upper end of the runner plate 1, a plurality of heat exchange runners 5 are arranged on the runner plate 1, and a water cooling joint 3 connected with the heat exchange runners 5 is arranged at one end of the runner plate 1 and one end of the flat plate 2.
In this embodiment, two through holes 6 for fixing the water-cooling joint 3 are provided at one end of the flat plate 2, and the medium in the water-cooling joint 3 is communicated with the heat exchange channels 5 through the through holes to realize heat exchange.
The outer edges of the two water-cooling joints 3 are welded with the flat plate 2, and the water-cooling joints 3 are welded and fixed with the flat plate 2 through furnace soldering.
The runner board 2 is close to the one end that water-cooling connects 3 and is equipped with the cramp muscle 4, and the cramp muscle 4 highly is less than the heat transfer runner 5 highly, and the cramp muscle 4 highly is less than the heat transfer runner 50.5mm, because of the tall design of cramp muscle is than cold plate runner highly low, do not contact with the bracket when welding, avoided the welding defect because of the difference in height, such as rosin joint, stranded gas drum package, unfused and not welded the problem.
