As shown in fig. 2 to 7, according to a first aspect of an embodiment of the present invention, a cavity structure 100 is provided, fig. 2 schematically shows a structural schematic diagram of the cavity structure 100 according to an embodiment of the present invention, and fig. 3 is a partially enlarged structural schematic diagram at a in fig. 2, as shown in fig. 2 and fig. 3. The cavity structure 100 may be applied to an integrated circuit module, where the cavity structure 100 includes a first plate-like member 10 and a second plate-like member 20, the first plate-like member 10 is provided with one or more first grooves 11 in the thickness direction, ends of the first grooves 11 form first stamping chamfers 12 when being manufactured by a stamping process, the second plate-like member 20 is covered and connected to the first plate-like member 10, the second plate-like member 20 is provided with one or more second grooves 21 in the thickness direction, ends of the second grooves 21 form second stamping chamfers 22 when being manufactured by the stamping process, the second grooves 21 are arranged corresponding to the first grooves 11, and the second grooves 21 and the corresponding first grooves 11 define a cavity, where a width of the second grooves 21 is greater than a width of the corresponding first grooves 11, that is, a width of a notch of the second grooves 21 is greater than a width of a notch of the first grooves 11, and of course, a width of a notch of the second grooves 21 may also be less than a width of a notch of the first grooves 11.
The utility model discloses a cavity structure 100, the width through the second recess 21 that will need the butt joint is inconsistent with the width of first recess 11, can make the setting of staggering of second punching press chamfer 22 of second recess 21 and first punching press chamfer 12 of first recess 11, reduces the size that forms the clearance between second recess 21 and the first recess 11, improves cavity structure 100's pressure resistance.
It should be noted that, the cavity structure 100 of the present invention is made in an integrated manner, and the first groove 11 of the first plate-like member 10 and the second groove 21 of the second plate-like member 20 are both made by a stamping process, so that the first stamping chamfer 12 is formed at the end of the first groove 11, and the second stamping chamfer 22 is formed at the end of the second groove 21. In the prior art, the first groove 11 and the second groove 21 have the same shape and the same size, and a large gap is formed on the contact surface between the first groove 11 and the second groove 21, and the position of the gap becomes a weak point of the cavity structure 100, which reduces the pressure resistance of the whole cavity structure 100. The utility model discloses be greater than or be less than the width of the notch of first recess 11 with the width of the notch of second recess 21, can close the setting of staggering the clearance that forms between first punching press chamfer 12 and the second punching press chamfer 22 when second plate part 20 and first plate part 10 lid are connected for cavity structure 100 diminishes in the clearance of this position, thereby has improved cavity structure 100's pressure resistance.
The notch here has three directions, the first being the depth direction of the notch, which is the same as the thickness direction of the first plate-like member 10, the second being the width direction of the notch, i.e., the left-right direction of the diameter of the first groove 11 in fig. 2, and the third being the length direction of the notch, i.e., the length direction shown by the first groove 11 in fig. 7. Similarly, the notches of the second grooves 21 have three directions, and the second grooves 21 are defined similarly.
In addition, it should be noted that, because the stamping process has low cost and high production efficiency, the stamping process is widely used in the production process of the pipeline integrated module 100, and therefore, the cavity structure 100 manufactured by the stamping process in the prior art needs to be improved to improve the pressure resistance of the cavity structure 100.
As can be seen from fig. 2, the cavity structure 100 of the present invention can make the gap become half of the original gap compared with the structure in the prior art, thereby obviously improving the pressure resistance of the cavity structure 100.
In addition, in fig. 2, the width of the notch of the second groove 21 is greater than the width of the notch of the first groove 11, or the width of the notch of the second groove 21 may be smaller than the width of the notch of the first groove 11, and the gaps formed by the first punched chamfer 12 and the second punched chamfer 22 may be arranged in a staggered manner, so as to reduce the size of the gap, thereby improving the pressure resistance of the cavity structure 100.
In alternative embodiments, the radius of the first convex arc 121 of the first punching chamfer 12 is 1-2.5 times the thickness of the first plate-like part 10 and/or the radius of the second convex arc 221 of the second punching chamfer 22 is 1-2.5 times the thickness of the second plate-like part 20, the first convex arc 121 of the first punching chamfer 12 being the arc of the side of the first punching chamfer 12 adjacent to the second groove 21 and, similarly, the second convex arc 221 of the second punching chamfer 22 being the arc of the side of the second punching chamfer 22 adjacent to the first groove 11.
By setting the radius of the first convex arc 121 of the first punching chamfer 12 to be 1-2.5 times the thickness of the first plate-like member 10, the punching quality of the first groove 11 can be ensured, and the occurrence of end cracking can be avoided, for example, the radius of the first convex arc 121 of the first punching chamfer 12 is 1.5 times or 1.8 times the thickness of the first plate-like member 10, and the like, which provides reference for a punching die. For example, when the thickness of the first plate-like member 10 is 10 mm, the radius of the first convex arc 121 of the first punched chamfer 12 may be 10-25 mm, such as 15 mm, 18 mm or 20 mm. Similarly, the radius of the second convex arc 221 of the second punching chamfer 22 is set to be 1-2.5 times of the thickness of the second plate-like part 20, so that the punching quality of the second groove 21 can be ensured, and the situation of end cracking can be avoided. In general, the thickness of the first plate-like member 10 and the thickness of the second plate-like member 20 may be different or the same, but the first plate-like member 10 and the second plate-like member 20 have the same thickness for easy processing in consideration of the convenience of processing and the pressure-bearing performance of the chamber structure 100. In addition, by setting the thicknesses of the first plate-like member 10 and the second plate-like member 20 to the same size, it is also possible to easily calculate the pressure resistance of the cavity structure 100.
In some optional embodiments, the cross-section of each of the first groove 11 and the second groove 21 is semicircular, that is, each of the first groove 11 and the second groove 21 is an elongated groove with a semicircular cross-section, of course, the first groove 11 and the second groove 21 may also adopt U-shaped grooves or grooves with other shapes, but considering that the cross-section of the pipe body is generally circular, therefore, the cross-section of each of the first groove 11 and the second groove 21 is preferably semicircular, so that the cavity structure 100 with a circular cross-section is formed after the first groove 11 and the second groove 21 are connected in a matching manner.
In alternative embodiments, the absolute value of the difference between the radius of the second groove 21 and the radius of the first groove 11 is 0.3-3 times the thickness of the first plate-like member 10, provided that the radius of the second groove 21 and the radius of the first groove 11 are not the same and the thickness of the first plate-like member 10 is the same as the thickness of the second plate-like member 20.
The second plate-like member 20 may have a flat plate-like structure, and the second groove 21 is not provided.

In some alternative embodiments, the connection structure of the first plate-like member 10 and the second plate-like member 20 is a brazing structure, and considering that the contact surface between the second plate-like member 20 and the second plate-like member 20 is an irregular planar structure, therefore, the brazing structure can ensure the welding rate between the first plate-like member 10 and the second plate-like member 20, improve the connection strength between the first plate-like member 10 and the second plate-like member 20, and prevent the fluid from entering the contact surface between the first plate-like member 10 and the second plate-like member 20 inside the chamber structure 100.
In some alternative embodiments, the brazing structure includes a brazing sheet disposed between the first plate-like member 10 and the second plate-like member 20, the brazing sheet is melted at a high temperature to form a brazing seam 40, the first plate-like member 10 and the second plate-like member 20 are connected, and a part of the brazing seam 40 is filled in a space of the gap, so that the connection strength between the first plate-like member 10 and the second plate-like member 20 is ensured, the size of the gap is reduced, and the pressure resistance of the cavity structure 100 is improved.
