This allows for different temperature control in the individual segments. It has been shown that for high heat transfer in a small device volume with shell element diameters of 60 mm and more, at least half of all web elements should be flowed through by the heat transfer fluid.
  • a casting process, an additive manufacturing process, a soldering process, an adhesive process, a shrink-fit process, a clamping process, and a welding process can all be cost-effective manufacturing processes for web elements and a shell element that is monolithically connected to the web elements without any gaps.

  • rectangular profiles can advantageously be used for the external geometry of the web elements, and the web element channel geometry can advantageously be selected as a round cross-section, i.e., in particular, a circular or oval cross-section.
  • This allows for the production of web elements with an ideal profile for cross-mixing and/or high inherent strength for high maximum fluid pressures. It has been shown that the web element channels for the heat transfer fluid in the web elements are advantageously produced by EDM after the casting process, and even more advantageously by drilling, allowing the production of web element channels with small diameters.
  • the heat transfer and/or mixing performance near the inner wall of the shell element is also significantly improved by the direct transition of the web elements into the shell element, since boundary layers of the fluid located on the inner wall also contribute to achieving optimal heat transfer or homogeneous mixing.
  • optimal renewal of the boundary layers can be achieved not only between the fluid and the shell element, but also between the fluid and the web element surface.
  • Optimal boundary layer renewal therefore leads to optimal use of the heat exchange surface.

  • the heat exchanger according to the invention exhibits a very narrow residence time spectrum for the fluid to be heated or cooled. This optimally prevents deposits or decomposition of the fluid.
  • a viscous fluid such as a polymer
  • a very low melt temperature close to the freezing point can be achieved thanks to the optimal renewal of the boundary layers.
  • This prevents solidified polymer from depositing on the heat exchange surfaces.

This allows the heat exchanger according to the invention to be built very compactly, especially for operation with viscous fluids.
  • the heat exchanger is generally suitable for mixing and cooling or heating any fluids such as liquids and gases, but especially for viscous and very viscous fluids such as polymers.
  • the shell element and the insert element can contain castable or weldable materials, for example metals, ceramics, plastics or combinations of these materials can be used.

  • the web element contains a web element channel, which is manufactured together with the insert shell element using the casting process or an additive manufacturing process, or is manufactured in a further process step using a drilling process or an erosion process.
  • an intermediate jacket element can be arranged which contains a first intermediate jacket element channel and a second intermediate jacket element channel, wherein the intermediate jacket element is positioned in the jacket element and the insert element is positioned in the intermediate jacket element such that the heat transfer fluid can flow from the jacket channel through the first intermediate jacket element channel into the web element channel, flow through the web element channel and flow from the web element channel through the second intermediate jacket element channel into the jacket channel.
  • an intermediate jacket element has several advantages.
  • the insert element can be manufactured significantly thinner and lighter. Therefore, a different material, for example a higher-quality material, can be used for the insert element than for the intermediate jacket element.
  • the insert element can contain a material that has high thermal conductivity or high resistance to chemicals, such as corrosion resistance.
  • the insert element can be manufactured as a single piece together with the web elements using an additive manufacturing process or casting process. Since the production of the insert element is very complex, it can be stored as a semi-finished product, and the intermediate jacket element can be adjusted to the required wall thickness depending on the application and nominal pressure.
  • the jacket element surrounding the intermediate jacket element can be designed as an additional double jacket through which the heat transfer fluid flows during operation. The heat transfer fluid passes through the openings in the jacket element and the intermediate jacket element as well as in the insert jacket element to at least one of the web elements, allowing it to flow through the web element(s).
  • the invention is not limited to the present embodiments.
  • the web elements can vary in number and dimensions. Furthermore, the number of web element channels in the web elements can vary depending on the required heat transfer.
