Thermal Performance of a Multi-Channel Heat Exchanger-Reactor
Resumo
A multi-functional heat exchanger-reactor comprising arborescent (tree-like) distributors and collector, 16 mini-channels in parallel and T-mixers is introduced in this paper. Thermal performance of proposed heat exchanger-reactor are experimentally tested and discussed. High global heat transfer coefficients ranging from 2000 to 5000
W·m−2·K−1 are obtained under our working conditions. The volumetric heat exchange capability (UA/V) is found
to be around 200 kW·m−3·K−1, showing a high heat exchange capability with compact design. A typical fast exothermic reaction, neutralization between acid and basic solutions, is carried out to test the thermal control capability of the studied heat exchanger-reactor. Results indicate that isothermal condition could be realized by circulating appropriate flowrate of coolant through the heat exchanger. The design of heat exchanger-reactor
with arborescent distributor and collector makes possible the application of multi-channel systems. This paper
introduces systematically the successful integration of heat exchanger-reactor and its performance evaluation.
