Abstract

The invention discloses a large-scale liquid-cooled pipe network and a welding method thereof, belonging to the technical field of large-scale liquid-cooled pipe network welding, including a liquid-cooled shell and a stepped cover plate, and the stepped cover plate includes a welded stepped cover plate and a reinforced stepped cover The reinforced stepped cover plate includes a plurality of steps corresponding to the pipelines at various levels, and each step is integrally formed with the welded stepped cover plate. In the present invention, the cover plate is designed as a stepped cover plate, and a design model based on bearing capacity is established. On the premise of ensuring that the pressure bearing capacity of the cover plate does not decrease, the thickness of the cover plate required for welding is greatly reduced, so that the welding process can be used Smaller stirring tools greatly reduce welding heat input and welding deformation; the welding thickness of the designed stepped cover plate is greatly reduced, which causes changes in the physical space design on both sides of the weld, because the width of one side of the weld is equal to the welding thickness, so the weld The physical space on both sides of the seam is greatly reduced, which improves the integration of large liquid cooling pipe networks and reduces the weight of the system.

Description

technical field

[0001] The invention relates to the technical field of large-scale liquid-cooled pipe network welding, in particular to a large-scale liquid-cooled pipe network and a welding method thereof. Background technique

[0002] The development of large-array and highly integrated radars puts forward an urgent demand for large-scale liquid-cooled pipe networks. While improving the integration of radars, large-scale liquid-cooled pipe networks greatly simplify the system assembly relationship, improve integration accuracy, and then improve the reliability of the radar system. and fighting power. With the development of advanced manufacturing technology, especially the maturity of friction stir welding technology, the manufacture of radar large-scale integrated pipe network becomes possible. Because there are a large number of high-precision radar electronic module installation interfaces on the integrated pipe network, and there are dense and complex flow channels in...
