MikrokanalWärmetauscher

MikrokanalWärmetauscher, often abbreviated as MKWT, refers to microchannel heat exchangers. These are devices designed for efficient heat transfer utilizing extremely small channels, typically with hydraulic diameters in the micrometer range (less than 1 mm). Their small size allows for a significantly larger surface area to volume ratio compared to conventional heat exchangers, leading to enhanced heat transfer coefficients.

The design of MikrokanalWärmetauscher can vary, but they commonly consist of multiple parallel microchannels etched or fabricated into plates or blocks. These channels can be made from various materials including metals, ceramics, and polymers, chosen based on factors like thermal conductivity, corrosion resistance, and cost. The fluids flow through these microscopic passages, facilitating rapid heat exchange between them.

MikrokanalWärmetauscher offer several advantages, including high thermal efficiency, compact size, and reduced fluid inventory. These characteristics make them suitable for a wide range of applications where space and weight are critical, or where precise temperature control is required. Examples include cooling of electronic components, automotive applications like radiators and intercoolers, refrigeration systems, and microreactors in chemical processing. Despite their benefits, challenges such as potential for clogging due to small channel size and manufacturing complexities exist.
