Energy Saving Consumption Reducing Aluminum Microchannel Heat Exchanger

Energy-Saving And Consumption-Reducing Aluminum Microchannel Heat Exchanger
   
 

  The channel diameters of traditional heat exchangers are mostly a few millimeters to tens of millimeters, and the fluid is prone to form laminar flow (smooth flow, heat is only transferred by molecular diffusion, low efficiency). The equivalent diameter of microchannels is only 10 to 1000 micrometers (about 1/5 to 1 times the diameter of a human hair), the flow rate of the fluid within the channel is higher (usually 0.5 to 5 m/s), and the thickness of the "boundary layer" (the thin layer with the greatest temperature gradient in the fluid) on the channel wall is significantly compressed (only a few micrometers to tens of micrometers). It is extremely easy to form turbulence (where the fluid is violently disturbed and heat is rapidly transferred through the fluid mixture). Ultimately, the convective heat transfer coefficient of microchannels can reach 500-5000 W/(m²·K), which is 2-20 times that of traditional finned tube heat exchangers (100-300 W/(m²·K)).
Freezer & chiller

In response to market demands, we have specifically developed a series of microchannel condenser standard products, focusing on meeting the extensive needs of household freezers, commercial freezers, display cabinets, ice makers, chillers, cold chains, chiller units, condensing units and other industries for high-efficiency condensers.
