[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0031] like Figure 1 and Figure 2 As shown, the utility model discloses a heat conducting plate 1, comprising a plate body 10 and a cover body 20 covered on the plate body 10. One side of the plate body 10 is concave to form a steam chamber 100; the cover body 20 is covered on the side of the plate body 10 where the steam chamber 100 is opened. Figure 2 and Figure 3 As shown, the plate body 10 is provided with at least one partition rib 200; the partition rib 200 separates at least two first partition chambers 300 from the steam chamber 100. Figure 2 and Figure 3 As shown, in this embodiment, one end of the partition rib 200 is connected to one side wall of the steam chamber 100, and the other end extends into the steam chamber 100 and has a gap 400 with the other side wall of the steam chamber 100, so that the partition rib 200 also separates a second partition chamber 500 from the steam chamber 100; the second partition chamber 500 is respectively connected to each first partition chamber 300. When the working fluid in the second partition chamber 500 is heated to form steam, the steam quickly flows from the second partition chamber 500 to the first partition chamber 300, and the steam quickly and orderly flows in the first partition chamber 300 along the extension direction of the first partition chamber 300 and quickly enters the heat sink fins 30.
[0032] like Figure 2 and Figure 3 As shown, in this embodiment, there are multiple dividing ribs 200, and the multiple dividing ribs 200 are distributed in parallel at equal intervals, so that the multiple first dividing chambers 300 separated are distributed in parallel with each other. The multiple first dividing chambers 300 are distributed in parallel, so that the steam in the steam chamber 100 is dispersed and enters the first dividing chamber 300; and the steam moves in the first dividing chamber 300 along the extension direction of the first dividing chamber 300, so that the steam in the steam chamber 100 moves in an orderly manner along the extension direction of the first dividing chamber 300; compared with the prior art in which the steam is in a chaotic and disordered state in a large steam chamber, in the utility model, the steam moves uniformly along the extension direction of the first dividing chamber 300 in the heat conducting plate 1, and the steam flows to the heat dissipation fins 30 more efficiently, thereby improving the heat dissipation efficiency of the heat conducting plate 1, and then improving the heat dissipation efficiency of the heat dissipation device 2.
[0033] like Figure 3 As shown, in this embodiment, a fin locking groove 310 is provided at one end of the first partition chamber 300 connected to the side wall of the steam chamber 100. Figure 4 and Figure 5 As shown, the cover body 20 is provided with at least two through slots 600 , and the first partition cavity 300 is communicated with at least one of the through slots 600 .
[0034] like Figure 6 and Figure 7 As shown, the utility model also discloses a heat dissipation device 2, which includes a heat conducting plate 1 and at least two heat dissipation fins 30. The heat dissipation fins 30 pass through the through slot 600 and extend into the first partition cavity 300; and each first partition cavity 300 corresponds to at least one heat dissipation fin 30. In this embodiment, the first partition cavity 300 and the heat dissipation fins 30 correspond to each other.
[0035] like Figure 8and Fig. 9 As shown, in this embodiment, the heat dissipation fin 30 is provided with at least one plug-in ridge 301, and the plug-in ridge 301 corresponds to the through groove 600; the plug-in ridge 301 passes through its corresponding through groove 600 and communicates with the steam chamber 100. Specifically, at least one plug-in ridge 301 of each heat dissipation fin 30 passes through its corresponding through groove 600 and extends to the first partition chamber 300; the plug-in ridge 301 is provided with at least one communication opening 302. When the heat dissipation fin 30 is plugged into the heat conducting plate 1, the communication opening 302 extends into the first partition chamber 300; in this embodiment, the number of the heat dissipation fins 30 is the same as the number of the first partition chamber 300, and the heat dissipation fins 30 and the first partition chamber 300 correspond to each other. In this embodiment, each heat dissipation fin 30 is provided with two corresponding plug-in ridges 301.
[0036] like Figure 8 and Fig. 9 As shown, in this embodiment, the plug-in ridge 301 is provided with at least one connecting portion 303, the connecting portion 303 protrudes in the vertical direction of the plug-in ridge 301, and the connecting port 302 is opened in the connecting portion 303. Figure 5 As shown, correspondingly, the through groove 600 is recessed toward both sides along the vertical direction of its extension to form an escape groove 610; the escape groove 610 corresponds to the connecting portion 303. When the plug-in ridge 301 is inserted into the through groove 600, the connecting portion 303 is aligned with the escape groove 610 and passes through the escape groove 610. After the connecting portion 303 passes through the escape groove 610, the heat dissipation fin 30 is connected to the first partition chamber 300 through the connecting port 302.
[0037] In this embodiment, after the plug-in rib 301 is inserted into the first partition cavity 300, the fin locking groove 310 of the first partition cavity 300 locks and limits the end of the plug-in rib 301. The fin locking groove 310 locks and limits the heat sink fin 30 by locking and limiting the plug-in rib 301, thereby improving the stability of the connection between the heat sink fin 30 and the heat conducting plate 1 and preventing the heat sink fin 30 from falling off.
[0038] like Figure 1 and Figure 3As shown, in this embodiment, one side of the separation rib 200 is connected to the bottom of the steam chamber 100, and the other side is in contact with the cover 20. A plurality of conductive support columns 700 are arranged in the steam chamber 100; one end of the conductive support column 700 is connected to the bottom of the steam chamber 100, and the other end is in contact with the cover 20. At least one conductive support column 700 is integrally arranged with the separation rib 200. Preferably, the conductive support columns 700 are evenly distributed in the steam chamber 100, and some conductive support columns 700 are integrally arranged with the separation rib 200. As a preferred embodiment, the conductive support column 700 is a circular cylinder. Of course, the conductive support column 700 can also be designed in other shapes. On the one hand, the conductive support column 700 provides support for the cover 20 to prevent the cover 20 from deforming under the pressure of the heat dissipation fins 30; on the other hand, the conductive support column 700 conducts the heat absorbed by the plate 10 to the cover 20, and the cover 20 conducts the heat to the heat dissipation fins 30 for heat dissipation. The heat dissipation device 2 of the utility model adopts both the refrigerant heat dissipation method and the conduction heat dissipation method, and the heat dissipation efficiency is greatly improved, and the heat dissipation effect is stable. In addition, the integral arrangement of the partial conduction support column 700 and the separation rib 200 enables the separation rib 200 and the conduction support column 700 to support the cover body 20 to prevent the cover body 20 from being deformed by force while quickly conducting the heat absorbed by the plate body 10 to the heat dissipation fins 30. The integral arrangement of the conduction support column 700 and the separation rib 200 optimizes the support function for the cover body 20, and at the same time increases the heat conduction path, further improving the heat dissipation efficiency of the heat conducting plate 1, and further improving the heat dissipation efficiency of the heat dissipation device 2.
[0039] like Figure 6 , Figure 8 and Fig.10 As shown, in this embodiment, the heat dissipation device 2 further includes at least one fixing bar 40; the fixing bar 40 is provided with at least two first slots 401, and the heat dissipation fin 30 is further provided with at least two second slots 304, and the first slots 401 and the second slots 304 correspond to each other. The fixing bar 40 fixes the heat dissipation fin 30, so that the heat dissipation fin 30 maintains a stable state and is not prone to loosening or falling off. As a preferred embodiment, the number of fixing bars 40 is three, and the three fixing bars 40 are fixed to at least two surfaces of the heat dissipation fin 30, which has a better fixing effect on the heat dissipation fin 30.
[0040] like Fig.10 As shown, in this embodiment, the heat sink 2 further includes a fin protector 50, which is a mesh structure and is connected to a side of the heat sink 30 away from the heat conducting plate 1. The fin protector 50 protects the heat sink 30 without affecting the heat dissipation effect of the heat sink 30.
[0041] The heat dissipation device 2 of the present invention is provided with a partition rib 200 on the heat conducting plate 1, and the steam chamber 100 is divided into two or more first partition chambers 300 by the partition rib 200, so that the steam in the heat conducting plate 1 is orderly conducted to the heat dissipation fins 30 along the first partition chamber 300 in a fixed direction, thereby improving the heat dissipation efficiency of the heat conducting plate 1, and further improving the heat dissipation efficiency of the heat dissipation device 2.
[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
