The invention relates to a heat exchanger comprising parallel plates and spacers arranged in parallel and defining i) rough primary channels and ii) secondary channels arranged so as to exchange heat. Said heat exchanger comprises a primary liquid inlet to be fluidically connected to a primary liquid dispenser. Each rough primary channel has the shape of a prism having a polygonal cross-section and consisting of a plurality of essentially flat faces. The primary channels comprise rough primary channels. Each rough primary channel has microstructure elements which are distributed along the entire length of the channel and have dimensions of between 1 μm and 300 μm.

The invention provides a phase transformation heat exchange device. The device includes an inner tube, an outer tube, and a heat exchange medium; the space between the inner tube and the outer tube forms a whole or a part of a liquid phase region; a whole or a part of space inside the inner tube forms a vaporization region; the heat exchange medium with a relatively high pressure inside the liquid phase region enters the vaporization region with a relatively low pressure while being heated in vortex flow, and flows out of the device after being vapored, so as to complete heat exchange. The device can be applied to DSG systems of the solar energy photothermal field, and can also be applied to an input-output system of a heat storage system, or the field of boiler heating. It is achieved with safe operation, low cost, and good application range.
