Disclosed is a micro-channel structure for a heat exchanger, and an integrated type micro-channel heat exchanger. The micro-channel structure is formed between a plurality of layers of heat exchange plates (1) placed in a stacked manner, with a plurality of fin units (2) formed on the heat exchange plate (1), and the fin units (2) are arranged uniformly into a fin unit group (9) in the direction perpendicular to a flow direction of a fluid, and several fin unit groups (9) are alternately arranged and spaced from one another by a distance in the flow direction of the fluid; the rear part of the upstream fin unit (2) is arranged in an intermediate position between the two adjacent downstream fin units (2); the fin unit (2) is composed of at least two spaced fins (21), with the adjacent fins (21) spaced from each other by a distance; and the fluid channels between the adjacent fin units (2) and between the adjacent fins (21) form the micro-channel structure. The integrated type micro-channel heat exchanger comprises a plurality of layers of heat exchange plates (1) placed in a stacked manner, and the above-mentioned micro-channel structure is formed between the heat exchange plates (1). |
