BXB series: It is a product out of Dr. Company with good heat dissipation structure, such as horseshoe, semi-circle or circle, which helps to dissipate heat quickly and reduce the effect of heat on the rectifier bridge. The rectifier bridge is designed with compatibility with generators in mind, making the installation process simple and easy. Bosch rectifier bridge is suitable for many types of automotive generators, not only limited to Bosch's own generator products; the pole plate material is stamped aluminum pole plate, copper seat single tube pressure mounting method, with good heat dissipation, most of the rectifier bridge structure for the left and right pole plate, basically with the excitation, part of the rectifier bridge connection has two kinds of there is a triangular connection and a star connection, suitable for the use of different types of motors; the Dr. series structure is simple, but Well-designed, with high-efficiency electrical energy conversion capacity, with high reliability and stability; Bosch generator advantages of stable performance, reliable quality, very durable, and is mainly supplied to Mercedes-Benz, BMW, Audi, Volkswagen, Porsche, and other automobile enterprises of the original supporting. Pre-aluminum plate outer round bending process left and right symmetrically mounted on the bracket, using the copper welding process, the late positive plate using die-casting aluminum, the negative plate using stamped aluminum structure, the use of 4-layer structure production mostly spot welding process production.
