Description

Technical Field

[0001] The utility model relates to the technical field of temperature equalizing plates, in particular to a temperature equalizing net positioning device. Background Art

[0002] The temperature equalizing net is set on the inner side of the temperature equalizing plate. The volume cavity formed by the upper and lower cover plates transfers heat to the liquid entering the inner side. The temperature equalizing net can effectively disperse heat and ensure that the temperature of the heated surface or area is uniform. The temperature equalizing net can avoid local overheating or overcooling.

[0003] During the preparation of the existing temperature-equalizing mesh, the mesh is placed on the inner side of the fixture. Since the mesh is thin and there is a tolerance in the matching dimensions of the fixture and the mesh, the mesh is easily deformed during the placement process. During the welding process, thermal expansion and contraction occur, affecting the processing accuracy of the mesh. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 4 The utility model provides an embodiment: a temperature-uniform network positioning device, comprising: a bottom plate 1; the bottom plate 1 is provided with positioning points 11, and the temperature-uniform network 2 is butt-welded to the bottom plate 1 through the positioning points 11 corresponding to the temperature-uniform network 2.

[0027] In this embodiment, positioning points 11 are provided on the base plate 1 to match the positions of the positioning holes 22 of the temperature-equalizing net 2 to form a plane overlap, thereby avoiding the problem of the temperature-equalizing net 2 being squeezed and deformed during the positioning process due to different dimensional tolerances. The base plate 1 and the temperature-equalizing net 2 are then butt-welded, and the temperature-equalizing net 2 is prevented from expanding and deforming due to temperature increase during the butt-welding process. At the same time, the use of jigs is reduced, thereby reducing the preparation cost of the temperature-equalizing net 2.

[0028] The bottom plate 1 includes a mounting portion 12 , one side of which extends outward to form a water guide portion 13 .

[0029] In this embodiment, during the process of assembling the temperature equalizing plate for water diversion and heat conduction, the liquid immersed in the volume cavity of the temperature equalizing plate is drained to the temperature equalizing net 2 through the water diversion part 13. The material of the temperature equalizing net 2 is preferably copper, which has good thermal conductivity and can quickly conduct heat.

[0030] The temperature-uniform network 2 is provided with a plurality of through holes 21 , which are arranged in an array.

[0031] In this embodiment, during the assembly of the temperature equalizing plate, a number of support columns are provided on the inner side of the shell, and the support columns are passed through the through holes 21 on the temperature equalizing net 2. On the one hand, the temperature equalizing net 2 can be positioned, and on the other hand, an interlaced flow channel can be formed with the temperature equalizing net 2 in the volume cavity, thereby increasing the contact area between the liquid and the temperature equalizing net 2 and improving the temperature equalization efficiency of the temperature equalizing net 2.

[0032] The temperature-uniform net 2 is further provided with a plurality of positioning holes 22 , which correspond to the positions of the plurality of positioning points 11 ; the mounting portion 12 is larger than the temperature-uniform net 2 , and the temperature-uniform net 2 overlaps with the mounting portion 12 .

[0033] In this embodiment, the positioning holes 22 are aligned with the positioning points 11 on the base plate 1 to determine the welding position of the temperature-uniform grid 2 for position calibration. During the positioning process, the base plate 1 and the temperature-uniform grid 2 overlap in plane, which can ensure the flatness of the temperature-uniform grid 2 and prevent deformation.

[0034] At least two positioning points 11 are provided on the mounting portion 12 , and at least two welding points are formed by performing butt welding on the edge of the temperature-uniform grid 2 and the end surface of the mounting portion 12 .

[0035] In this embodiment, four positioning points 11 are provided on the mounting portion 12, and the four positioning points 11 are located at the four corners of the mounting portion 12, so that the positioning of the temperature-uniform grid 2 is more accurate. During the butt welding process, butt welding is performed at the joint between the temperature-uniform grid 2 and the mounting portion 12 to fix the position of the temperature-uniform grid 2. In order to prevent the temperature-uniform grid 2 from being loosened during welding, the temperature-uniform grid 2 needs to be butt welded multiple times.

[0036] Grooves are provided on both sides of the mounting portion 12 adjacent to the water diversion portion 13 .

[0037] In this embodiment, the grooves on both sides of the mounting portion 12 are arranged on the outside of the temperature-uniform grid 2, which will not affect the butt welding of the temperature-uniform grid 2 and facilitate clamping during the mobile butt welding process.

[0038] The matching accuracy between the bottom plate 1 and the temperature-uniform net 2 is [-1mm, 1mm]; the thickness of the temperature-uniform net 2 is 0.1-0.2mm.

[0039] In this embodiment, the temperature-equalizing net 2 is relatively thin and easily deformed. The plane of the temperature-equalizing net 2 is supported by the base plate 1 to reduce the problem of deformation. The matching accuracy between the positioning point 11 of the base plate 1 and the positioning hole 22 is [-1mm, 1mm], and the temperature-equalizing net 2 is welded.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
