Microchannel Plate Heat Exchanger

The micro-channel plate heat exchanger is a highly efficient, compact heat exchange device that integrates the advantages of micro-channel technology and plate structure design. It is fabricated by stacking and welding multiple layers of precision metal flow channel plates, forming numerous micro-channels with millimeter-scale cross-sections between plates to enable efficient heat transfer between hot and cold fluids. Key features include high heat transfer efficiency, compact structure, and resistance to high temperatures and pressures.

Product Features

High-Efficiency Heat Transfer

Featuring a microchannel design, the heat-exchange core is formed by stacking and welding flow-channel plates fabricated through chemical etching or precision machining. This configuration delivers significantly higher heat-transfer efficiency than traditional heat exchangers. Its compact structure enables a much larger heat-exchange area per unit volume, making it ideal for high-heat-load applications.
Compact Structure

The product’s overall structure is highly integrated, achieving a compact layout through modular design. Compared with traditional shell-and-tube heat exchangers, its volume is reduced by more than 50%, greatly saving installation space.
High-Temperature and High-Pressure Resistance

The heat-exchange core is manufactured using vacuum diffusion welding technology, allowing it to withstand extreme pressures and temperature ranges, and making it suitable for demanding environments such as nuclear power and hydrogen energy.
Safe and Reliable

Diffusion welding enables gasket-free design, eliminating leak risks.

All-metal solid-state diffusion bonding process

The heat-exchange core adopts an all-metal solid-state diffusion bonding process, achieving metallurgical bonding between multiple layers of metal plates. This eliminates gaskets, brazing layers, and mechanical seals, thereby removing potential leakage points in the structure and ensuring intrinsic safety and long-term sealing reliability under extreme operating conditions.
Counter-flow configuration

A minimum temperature difference of less than 5°C can be achieved between the hot and cold ends, enabling highly efficient heat recovery. The combination of micro-channel enhanced heat-transfer mechanisms and diffusion-bonding technology significantly improves heat-transfer performance.
High integration and multi-medium compatibility

The equipment uses nickel-based alloys, stainless steels, and special corrosion-resistant materials, ensuring compatibility with complex media such as hydrogen, liquid oxygen, and supercritical fluids. It supports multi-stream integration, enabling three or more fluids to exchange heat within a single device to meet the needs of highly integrated systems.
Thermal-mechanical coupling for extreme conditions

The core structure is designed to withstand the maximum design pressure of fluids on both sides at the maximum operating temperature. It offers excellent thermal-mechanical coupling capability and is suitable for ultra-high-pressure, cryogenic, and high-temperature environments.
