The aluminum-plastic structure is connected in a buckling and sealing mode, the aluminum main sheet 2 is bent by buckling process equipment, and the edge of the plastic air chamber 1 is used as a fulcrum to bend in the bending process; because the main sheet has better strength after being bent, but the plastic air chamber 1 bears large horizontal pushing force during bending, the strength of the air chamber 1 is insufficient, the main sheet 2 often collapses and deforms, and the plastic air chamber 1 cracks seriously.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the main leaf that appears sinks when air chamber and main leaf withhold warp, air chamber fracture, the utility model aims to provide an automobile intercooler's main leaf structure.

The purpose of the utility model is realized through the following technical scheme:

the main sheet of the utility model is of a rectangular plate structure, the long edge and the short edge of the bottom plate are both bent towards the same side to form a flanging long edge and a flanging short edge, and a plurality of strip-shaped holes are uniformly arranged on the bottom plate along the length direction; the top of the long edge of the flange and the top of the short edge of the flange are respectively and uniformly provided with a plurality of great wall teeth, wherein both sides of the root of each great wall tooth on the short edge of the flange are provided with inward concave grooves;

wherein: the inner wall of the groove in the height direction is arc-shaped, and the inner walls of the upper side and the lower side of the inner wall in the height direction in the length direction are straight edges or bevel edges;

the inner wall of the groove in the height direction is semicircular, and the inner walls of the upper side and the lower side of the inner wall in the height direction in the length direction are symmetrically arranged in the circle center of the semicircle;

the depth of the groove is 1/8-1/6 of the tooth width of the long-tooth;

and flanges are arranged at the edges of the strip-shaped holes in the bending directions of the long edges and the short edges of the bottom plate.

The utility model discloses an advantage does with positive effect:

the utility model provides an aluminium-plastic car intercooler's main leaf structure weakens breach (recess promptly) according to addding intensity to the root of each long city tooth on the main leaf turn-ups weak point, withholds the in-process, and the deformation point of bending has reduced the face width of bending along recess lateral deformation, effectively reduces plastics air chamber side direction atress, avoids the plastics air chamber because of the too big fracture of minor face flat thrust, has also avoided the deformation that the main leaf caused because of the flat thrust is too big simultaneously.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 2 and 3, the main piece 2 of the present invention is a rectangular plate-shaped structure, the long side and the short side of the bottom plate 7 are both bent toward the same side (i.e. toward the direction of press-fitting contact with the air chamber 1) to form a flanged long side 8 and a flanged short side 9, a plurality of bar-shaped holes 12 are uniformly formed along the length direction on the bottom plate 7, and the heat dissipation belt 4 and the cooling pipe 5 of the intercooler are inserted into each bar-shaped hole 12; in order to be welded firmly to the heat dissipation band 4 and the cooling pipe 5, the edges of the strip-shaped holes 12 of the present embodiment are provided with flanges in the bending direction of the long side and the short side of the bottom plate 7.

The top of the flange long side 8 and the top of the flange short side 9 of the embodiment are respectively and uniformly provided with a plurality of long merlons 10, wherein both sides of the root of each long merlons 10 on the flange short side 9 are provided with inward concave grooves 11; the groove 11 may be formed by a press working. In order to further reduce the stress on the root part after each great wall tooth 10 on the flanged short edge 9 is buckled and pressed and further avoid the deformation of each great wall tooth 10 on the flanged short edge 9, the inner wall of the groove 11 in the height direction is arc-shaped; the upper and lower lengthwise inner walls of the height-direction inner wall are straight (as shown in fig. 4) or inclined (as shown in fig. 5). Preferably, the inner wall of the groove 11 in the height direction is semicircular, and the inner walls in the length direction of the upper and lower sides of the inner wall in the height direction are symmetrically arranged at the center of the semicircle. The depth of the groove 11 of the present embodiment is 1/8-1/6 of the tooth width of the great wall tooth 10, so as to ensure the press-fitting strength of each great wall tooth 10 on the flanging short side 9.

The root of each great wall tooth 10 on the turn-up minor face 9 of the main piece 2 is provided with a groove 11, so that the root of the great wall tooth 10 on the turn-up minor face 9 is equivalent to taking out part of the material, thereby reducing the strength of the bending part, avoiding the cracking of the plastic air chamber 1 and the bending deformation of the main piece 2, and realizing the integral buckling.
