Heat exchanger for internal combustion engines with s-shaped components
The patent US12065993B2 describes a heat exchanger specifically designed for internal combustion engines. The invention features a configuration that includes multiple tubes forming a first channel system for a first fluid, alongside a second channel system for a second fluid, which is fluidically separated from the first. The design incorporates two opposite side parts that bound the second channel system, with the tubes arranged in between. A notable aspect of the invention is the edge reinforcement of at least one side part, which includes an S-shaped tab bent over, featuring a first section solder-plated on the outside and a second section solder-plated on the inside. The frame part of the heat exchanger is structured with an S-shaped cross-section that includes a U-shaped receptacle to accommodate the first tab section.
Additional claims detail specific dimensions and structural features of the heat exchanger. For instance, the first tab section may have a width of approximately 15 mm, while the thickness of the side parts is around 1.2 mm. The design also allows for perforations or recesses in the first tab section, enhancing its structural integrity. The solder connections between the frame part and the side parts are emphasized, ensuring a robust assembly. The patent further outlines that the second tab section overlays the first, with no solder plating on its outer side, which may contribute to the overall efficiency and durability of the heat exchanger. This innovative design aims to improve the performance of internal combustion engines by optimizing fluid dynamics within the heat exchanger system.
