Description

Technical Field

[0001] The utility model relates to the technical field of vapor chambers, in particular to a vapor chamber with a supporting structure. Background Art

[0002] The heat spreader is a vacuum cavity with a capillary structure on the inner wall. The cavity is evacuated and filled with working fluid. When heat is transferred from the heat source to the evaporation zone, the working fluid in the cavity undergoes liquid gasification in a low vacuum environment. The working fluid absorbs heat energy and expands rapidly in volume. The gas phase working fluid quickly fills the entire cavity. When it contacts the condensation end, condensation occurs, thereby releasing heat energy. The condensed liquid working fluid flows back to the evaporation end due to the capillary structure. This process repeats itself in the cavity, thereby meeting the heat dissipation requirements.

[0003] The internal support structure of the heat spreader in the prior art utilizes more than two columns distributed in the inner cavity of the heat spreader. The support structure formed by the more than two columns must separate the columns from each other and place them one by one inside the body of the heat spreader. This requires a lot of manpower, and the process is tedious and complicated, and time-consuming. Therefore, we need to propose a heat spreader with a support structure. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a heat sink with a support structure, comprising:

[0024] An upper cover plate 2 and a lower cover plate 1, a heat exchange cavity is formed between the upper cover plate 2 and the lower cover plate 1, a plurality of component connection upper frames 4 are arranged below the upper cover plate 2, and a honeycomb support bottom frame 3 is arranged above the lower cover plate 1;

[0025] The honeycomb support chassis 3 includes a support main board 31, and a plurality of support outer frames 33 are fixedly connected to the upper surface of the support main board 31, and inner frame connection holes 35 are opened on both sides of the plurality of support outer frames 33;

[0026] The multiple groups of split connecting upper frames 4 all include a split plate 41, and the lower surface of the split plate 41 is fixedly connected to multiple groups of limiting inner frames 42. The lower ends of both sides of the multiple groups of limiting inner frames 42 are fixedly connected to limiting blocks 44 that are clamped in the inner frame connecting holes 35. The upper end of each group of supporting outer frames 33 is provided with a socket 36 for the limiting inner frame 42 to be plugged in.

[0027] The lower surface of the supporting main board 31 is provided with lower through holes 34 connected with multiple groups of supporting outer frames 33. The multiple groups of lower through holes 34 are arranged in a rectangular array. The upper surface of the supporting main board 31 is fixedly connected with multiple groups of main board reinforcing ribs 32. The multiple groups of main board reinforcing ribs 32 are arranged at equal intervals. The strength of the supporting main board 31 is improved by the reinforcing ribs, thereby improving the overall strength of the heat spreader and preventing the heat spreader from deformation.

[0028] The upper surface of each group of the split plates 41 is provided with an upper through hole 43 connected to the limiting inner frame 42. The multiple groups of the limiting inner frames 42 are arranged at equal intervals, which facilitates heat transfer through the split plates 41, increases the range of heat conduction, and thus improves its heat dissipation effect.

[0029] The lower ends of the multiple groups of the limiting inner frames 42 are all provided with through holes 45 for connecting the upper through holes 43 and the lower through holes 34. The inner diameter of the upper through holes 43 is smaller than the inner diameter of the lower through holes 34. The through holes 45 are convenient for connecting the lower through holes 34 on the supporting bottom plate with the upper and lower through holes 43 on the split plate 41, so as to facilitate the working fluid to expand and absorb heat inside the heat spreader and then condense and dissipate heat.

[0030] The horizontal cross-section of the supporting outer frame 33 is set in an equilateral hexagonal shape, and the horizontal cross-section of the insertion hole 36 is the same as the horizontal cross-section of the limiting inner frame 42. The horizontal cross-section of the limiting inner frame 42 is set in an equilateral hexagonal shape. The shape setting of the supporting outer frame 33 and the limiting inner frame 42 improves the stability of the support and facilitates the heat conduction of the working medium. At the same time, the limiting inner frame 42 and the supporting outer frame 33 improve the support stability of the upper cover plate 2 and the lower cover plate 1, and ensures the flatness of the surface of the heat spreader after production.

[0031] The length of the limiting inner frame 42 is smaller than that of the supporting outer frame 33, the insertion hole 36 is connected with the two groups of inner frame connecting holes 35, one end of the limiting block 44 is rounded, the limiting inner frame 42 and the supporting outer frame 33 are convenient to connect, and the assembly efficiency is improved.

[0032] A docking frame 5 is provided along the edge of the upper surface of the upper cover plate 2, and a docking groove 6 for the docking frame 5 to be embedded is opened along the edge of the lower end of the inner cavity of the lower cover plate 1, so that the upper cover plate 2 and the lower cover plate 1 can be docked conveniently through the docking frame 5 and the docking groove 6, thereby improving the assembly quality of the heat spreader and reducing the workload of the staff.

[0033] When in use, the limiting inner frame 42 on the lower surface of the multi-component split plate 41 is inserted into the socket 36 of the supporting outer frame 33 on the supporting main board 31, and then the limiting blocks 44 on the limiting inner frame 42 are matched with the inner frame connecting holes 35 on both sides of the supporting outer frame 33, so that the supporting outer frame 33 and the limiting inner frame 42 are stably connected to avoid separation of the supporting outer frame 33 and the limiting inner frame 42. The above operation is repeated many times to complete the installation of the honeycomb supporting base frame 3 and the split connecting upper frame 4, so as to facilitate the installation of the honeycomb supporting base frame 3 and the multi-component split connecting upper frame 4 connected as one between the upper cover plate 2 and the lower cover plate 1. The process is simple and the production efficiency of the heat spreader is improved.
