The aluminum profile structure of the radiator adopts a protective split mold with expansion, which is designed to eliminate the bending of the split bridge due to elastic deformation during the extrusion process, resulting in significant deformation stress. In order to better eliminate this stress and improve the strength of each split bridge, the heat dissipation of the profile radiator is good on the end face that matches the protective mold and the upper mold, and the characteristics of the aluminum profile are very obvious, If aluminum profile manufacturers use radiators of the same specification in the same room, the number of aluminum cast sheets is less than that of steel. The aluminum profile is designed as a conical surface with a depth of 1mm at the center, creating an elastic deformation space between the protection mode and the upper mold assembly. Choose an aluminum profile radiator and a high-pressure cast aluminum module combination radiator. This type of radiator is formed by one complete die casting, so there is no problem of weld leakage. Moreover, the advantage of its large aluminum profile is that the product is not limited by the residential heating system, and even in an open boiler system, it can be free from oxygen corrosion. Due to the modular combination design, it effectively protects the diversion bridge and improves the service life of the mold.
