[0033] The second chip 2 includes a second bottom plate 11 and an upward second flange 12, the included angle between the second flange 12 and the second bottom plate 11 is 90° to 105°, the second flange 12 is arranged around the second bottom plate 11, and the second flange 12 is provided with a third notch 13 for the first medium to flow in and a fourth notch 14 for the first medium to flow out at one end away from the second bottom plate 11.

[0034] The outer wall of the second flange 12 of the second chip 2 is welded to the inner wall of the first flange 8 of the adjacent first chip 1 below. The first notch 9 and the second notch 10 of the first chip 1 adjacent to the lower portion of the second chip 2 are both located below the second bottom plate 11 of the second chip 2. The second bottom plate 11 of the second chip 2 and the first bottom plate 7 of the adjacent first chip 1 below form a first medium channel. After stacking, the first notch and the second notch overlap with the third notch and the fourth notch respectively to form a first medium inlet and outlet. The water channel corresponds to the oil inlet and outlet positions through a spacer ring or a chip convex bump to isolate the oil circuit so that the oil and water circuits are not connected to each other.

The first welding bosses 15 and the second welding bosses 16 are welded one by one. A spacer can be placed at the corresponding oil port position, or a convex structure consistent with the boss direction can be set.

[0039] The first chip 1 and the second chip 2 are stacked and welded in the vertical direction to finally form the plate-fin heat exchanger structure 17 provided by the present invention. The oil flow direction 18 and the water flow direction 19 of the plate-fin heat exchanger structure 17 are as follows: Fig.15 shown.

[0040] The present invention provides a plate-fin heat exchanger structure that efficiently utilizes water flow.

[0043] The laminated plate-fin structure ensures the use requirements of the original plate-fin cooler products; the laminated plate-fin structure is welded on both sides of the product width direction, which has a water-blocking effect, ensuring that more water flows through the cooler, improving the water flow utilization rate and the heat dissipation. The laminated plate-fin structure adopts a laminated form, which improves the product welding qualification rate.

[0044] In addition, in addition to the notches at the positions shown in the figure, the stacked chips can also have notches at other different positions to form water channels.

[0045] Compared with the left view of the conventional plate-fin structure ( Figure 5 ) and the left view of the laminated plate fin structure ( Fig.14 ), that is, the width direction of the plate-fin structure, it can be seen that the water flow of the conventional plate-fin structure is open, while the water flow of the laminated plate-fin structure is closed.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
