A tendency to increase the importance of so called dispersed generation, based on the local energy sources and the working systems utilizing both the fossil fuels and the renewable energy resources is observed nowadays. Generation of electricity on industrial or domestic scale together with production of heat can be obtained for example through employment of the ORC systems. It is mentioned in the EU directive 2012/27/EU for cogenerative production of heat and electricity. For such systems the crucial points are connected with the heat exchangers, which should be small in size but be able to transfer high heat fluxes. In presented paper the prototype microjet heat exchanger (MJHE) dedicated for ORC systems is introduced. It was assembled at Faculty of Mechanical Engineering – Gdansk University of Technology, Poland. Its novel construction is described together with the systematical experimental analysis of heat transfer and flow characteristics. Reported results showed high values of the overall heat transfer coefficient and slight increase in the pressure drop. Despite increase in the flow resistance, the results are promising, because the heat transfer gain overcame the pressure loss. The results of microjet heat exchanger were compared with the results of commercially available compact plate heat exchanger (PHE).
