Fixing device for welding baffle rod in heat exchanger

The utility model relates to the field of heat exchanger manufacturing, in particular to a fixing device for welding a baffle rod in a heat exchanger. The fixing device for welding the baffle rod in the heat exchanger is used for fixing and limiting the baffle rod in the process that the baffle rod is welded to a baffle ring and comprises a supporting table and a fixing part, a first groove is formed in the supporting table, one end of the baffle rod is arranged in the first groove, the other end of the baffle rod is arranged on the surface of the baffle ring, and the fixing part is arranged in the first groove. The supporting table and the baffling ring can be detachably connected through the fixing part. According to the fixing device, through the supporting table and the fixing part, when the baffling rod is welded to the baffling ring, the baffling rod can be fixed, displacement of the baffling rod is limited, and the position, welded to the baffling ring, of the baffling rod is more accurate. 本实用新型涉及换热器制
