Preferably, the heat exchanger channels 40 can be microchannel.Microchannel refers to channel equivalent diameter at 10-1000 μm
Heat exchanger channels.As shown in Figure 1, the microchannel can be the multiple of side-by-side parallel setting, and multiple microchannels are uniform
It is distributed between first heat exchange layer 10 and second heat exchange layer 20.For example, in terms of household air conditioning applications, when heat exchange is logical
When road size is less than 3mm, gas liquid two-phase flow will differ from conventional large-size with phase-change heat transfer rule, and heat exchanger channels are smaller,
This dimensional effect is more apparent.When heat exchanger channels internal diameter it is small to 0.5~1mm when, convection transfer rate can increase 50%~
100%.This heat transfer enhancement technology is used for air-conditioning heat exchanger, suitably changes the reinforcing of heat exchanger structure, technique and air side
Heat transfer measure can effectively enhance the heat transfer of air-conditioning heat exchanger, improve its energy-saving horizontal.Compared with usual heat exchanger, microchannel is changed
