The utility model relates to the technical field of thermal management, and discloses a radiator with an insert substrate, which comprises an insert substrate and radiating inserts, the top of the insert substrate is fixedly connected with a plurality of mounting seats, the bottom of each radiating insert is provided with a fixing component, the fixing component comprises a plurality of mounting columns, and the mounting columns are fixedly connected with the mounting seats. The multiple installation columns are fixedly connected to the bottoms of the heat dissipation insertion pieces, at least one rubber ring is fixedly connected to the outer side of each installation column, multiple installation holes are formed in the top of the installation base, grooves are formed in the installation holes, and heat dissipation fins are fixedly connected to the two sides of each heat dissipation insertion piece. According to the utility model, a sliding connection mode of the mounting columns and the mounting holes is adopted, and interference fit is formed through the rubber rings and the grooves, so that the functions of conveniently mounting and dismounting the heat dissipation insertion sheets are achieved. Compared with a traditional fixed installation mode, the design enables the heat dissipation inserting pieces to be rapidly replaced or adjusted, and the problem that the heat dissipation inserting pieces are tedious and time-consuming to replace in the prior art is solved.

The utility model relates to the technical field of rotary kiln combustion-supporting, in particular to a rotary kiln combustion-supporting air inlet structure, which comprises a heat exchange bin, a plurality of heat conducting pipes are fixedly installed inside the heat exchange bin, a gas distribution assembly is arranged at the lower end of the heat exchange bin, and a stirring assembly is arranged inside the heat exchange bin, wherein the stirring assembly comprises a supporting ring fixedly installed at the upper end inside the heat exchange bin, and stirring blades are fixedly installed on the outer surface of the rotating frame. In the utility model, the secondary air flows through the plurality of heat conducting pipes, so that the pulverized coal exchanges heat when flowing through the heat exchange bin, part of the heat in the secondary air preliminarily heats the pulverized coal, the heat of the secondary air is fully utilized, the heated pulverized coal is then mixed into the tertiary air, the tertiary air heats the pulverized coal, the temperature of the pulverized coal before combustion is further improved, the pulverized coal is more convenient to burn, the time required for heating the pulverized coal inside the combustion chamber is reduced, the influence of the time on combustion is reduced, and the combustion effect of the material is improved.
