Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
A kind of heat exchanging core, comprise some stacked plastic uptake chip modules 1 that are bonded together, plastic uptake chip module comprises that the first plastic uptake sheet 1l and the second plastic uptake sheet 12, the first plastic uptake plate shapes are hexagon, the rectangular slab of central authorities is heat exchanger plate 11l, and the triangular plate of both sides is wind deflector 112; Heat exchanger plate surface is the waveform fold of continuous distributed, and fold is the place of projection 113 in heat exchanger plate front, corresponds to groove at the heat exchanger plate back side; Fold is the place of groove 114 in heat exchanger plate front, corresponds to projection at the heat exchanger plate back side, and projection and groove cross sectional shape are triangle; Space between the positive projection of heat exchanger plate and groove forms the first hot switching path 115, space between the positive projection in the heat exchange class back side and groove forms between the second hot switching path 117, the first hot switching paths and the second hot switching path and does not communicate; Wind deflector front is provided with some the first parallel air-guiding aisles 116;
The second plastic uptake sheet is located at the first plastic uptake sheet back side, and shape is identical with the first plastic uptake sheet, is also hexagon, and the position of central corresponding heat exchanger plate is plane, and the position of the corresponding wind deflector in both sides is provided with some the second parallel air-guiding aisle 12l.
It is upper that the air inlet of the first air-guiding aisle and air outlet are positioned at hexagonal one group of contrast, and the air inlet of the second air-guiding aisle and air outlet are positioned in hexagonal another group contrast.
The first air-guiding aisle surrounds by some parallel lug, nibs 2 with the second air-guiding aisle, and lug, nib extends to the intersection of wind deflector and heat exchanger plate from wind deflector outer ledge.
An a lot of plastic uptake chip module formation columnar core stacked together, core body upper surface is stamped cover plate 3, and side is provided with extrusion molding bar 4.
