Latest Patents

Ohashi holds a patent for a heat exchanger and method for producing the same. This invention involves a pair of header plates that are securely brazed with a pair of side plates, ensuring that there is no buckling of tubes or deformation of the header plates. The process begins with each tube being press-fitted into corresponding holes in the header plates. The end parts of the side plates then make contact with the header plates. Following this, flaring pins are press-fitted into the end parts of the tubes, allowing for specific angles of flaring that enhance the assembly's stability. Finally, the cores are hung from the upper header plates, and the entire assembly is brazed, preventing any downward sliding of the header plates.
