  • Cylindrical air to air heat exchanger
    Patent number: 11486649
    Abstract: A heat exchanger for heat exchange between at least two fluids includes a plurality of heat exchange elements each having at least one fluid-guiding path for conducting at least one of the fluids through. The heat exchanger has a cylindrical shape or substantially cylindrical shape with a cylinder axis around which the heat exchange elements are adjacently arranged. At lease a region of each of the heat exchange elements forms an outline structure at least substantially like one of a triangular cylinder, a trapezoidal cylinder, a circle-sector cylinder, and an annulus-sector cylinder. As a result of adjacent arrangement of the heat exchange elements, the heat exchanger or at least a region of the heat exchanger has an outline structure at least substantially like one of a polygonal cylinder, a polygonal hollow cylinder, a circular cylinder, and annular cylinder. The cylindrical shape of the heat exchanger may alternatively be a cone frustum. The heat exchanger may be incorporated into an air device.
