The utility model relates to a welded copper square fixed cooling plant which solves the defects in the prior art that circular tube welding is subjected to deviation possibly, or the strength of a welding seam is not high because of insufficient part brazing alloy smelting. The cooling plant comprises cooling boards and a plurality of copper blocks bonded with the cooling board, wherein a steel pipe through-hole is formed in the middle of the copper blocks after the copper blocks are spliced, cooling passages communicated with each other are processed inside the cooling boards, the steel pipe is clamped through four copper blocks, and the copper blocks are inserted into a slot surrounded by guide ribs of a first cooling board and fixed by a cover plate and a second cooling board. The cooling plant has the advantages of convenient installation; and communicated cooling passages are arranged in the cooling boards and filled with cooling water, thereby quickly lowering the temperature of the steel pipe, and imp
