Description
TECHNICAL FIELD
[0001] The utility model relates to the field of heat dissipation, specifically to a heat dissipation plate and a wind force heat dissipator. BACKGROUND
[0002] With the rapid development of modern industry and national defense science and technology, the intelligentization, integration, localization and standardization of electronic equipment are more and more important, but the heat dissipation of the electronic components inside the equipment is higher and higher, and the heat is the "number one enemy" of the electronic equipment, and the high temperature will seriously affect the performance and service life of the electronic equipment. The air cooling heat dissipation is widely used in the heat dissipation of electronic equipment because of its mature technology, low cost and reliable performance, but the traditional air cooling heat dissipator still has the problems of low heat dissipation efficiency and cannot meet the heat dissipation requirements of the equipment.
[0003] At present, in the structure design of the air cooling heat dissipator, in order to improve the heat dissipation efficiency of the heat dissipator, the following two structure forms are usually adopted.
[0004] The first kind (machining type): the structure form of the heat dissipation rib in the heat dissipator is straight tooth and needle, the advantages of this type are that the traditional machining process can be used for machining, the process is simple, the manufacturing cost is low, and the thickness size of the straight tooth and needle can be specially designed according to the heat dissipation; but the defects are that the straight tooth and needle structure cannot provide larger surface area, and cannot further improve the heat dissipation efficiency of the heat dissipator.
[0005] The second kind (corrugated plate type): the structure form of the heat dissipation rib in the heat dissipator is rectangular corrugated plate and triangular corrugated plate punched by a die, the advantages of this type are that the corrugated plate can provide larger surface area under the same size, and the heat dissipation efficiency is obviously higher than the first kind; but the defects are that the corrugated plate is a profile produced by die punching, so its wall thickness is thin (mostly 0.15mm-0.3mm), which leads to that the heat on the heat dissipator cannot be well conducted along the heat dissipation rib to the whole heat dissipation air duct, thereby affecting the heat dissipation efficiency of the heat dissipator. CONTENT OF THE UTILITY MODEL
[0006] Therefore, in order to solve the above problems, the utility model provides a heat dissipation plate and a wind force heat dissipator, wherein the heat dissipation plate is provided with a plurality of heat dissipation main ribs and heat dissipation side ribs, which are interwoven to form a tree-shaped heat dissipation plate, thereby improving the heat dissipation efficiency.
[0007] On the one hand, the utility model provides a heat dissipation plate, the heat dissipation plate includes a frame, a plurality of heat dissipation main ribs extending to a first direction are arranged in the frame, and the first direction is a direction away from the heat source;
[0008] The two sides of the adjacent heat dissipation main rib are provided with heat dissipation side branch ribs which are inclined and extend to the first direction, and the heat dissipation side branch ribs extend to the adjacent heat dissipation main rib or / and the lower part of the frame.
[0009] Optionally, the width of the heat dissipation main rib and the heat dissipation side branch gradually decreases along the first direction.
[0010] Optionally, the average width of the heat dissipation main rib is greater than the average width of the heat dissipation side branch.

[0013] In another aspect, the utility model provides a wind force heat radiator, including heat radiator frame, at least in heat radiator frame one side surface installation is as described heat dissipation plate.
[0014] The utility model has the advantages of:
[0015] The utility model discloses a heat dissipation plate and a wind force heat radiator, wherein the heat dissipation plate is provided with a plurality of heat dissipation main ribs and heat dissipation side branch ribs, which are interwoven to form a tree-shaped heat dissipation plate. During heat dissipation, the position close to the heat source is taken as the root of the heat dissipation rib, and the main rib, the main branch rib and the side branch rib are derived in turn according to the change rule from thick to thin, so as to ensure that more heat of the root can be conducted to other positions through the main rib, thereby improving the heat dissipation efficiency. The wind force heat radiator is improved on the basis of the traditional wind force heat radiator. Specifically, the heat dissipation plate is installed on at least one surface of the heat radiator frame. The heat dissipation plate and the heat radiator frame can be combined into an integral structure by using the 3D printing process.

[0022] Embodiments of the present application are described below in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0023] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
[0024] As described in the background, in the current air-cooled heat sink structure design, in order to improve the heat dissipation efficiency of the heat sink, the following two structure forms are usually adopted.
[0025] The first (machining type): the structure of the heat dissipation rib in the heat sink is straight-toothed and needle-shaped. The advantage of this type is that it can be machined by using traditional machining process, the process is simple, the manufacturing cost is low, and the thickness size of the straight-toothed and needle-shaped structure can be specially designed according to the heat dissipation power. But the defect is that the straight-toothed and needle-shaped structure cannot provide a larger surface area, and cannot further improve the heat dissipation efficiency of the heat sink.
[0026] The second (corrugated plate type): the structure of the heat dissipation rib in the heat sink is a rectangular corrugated plate and a triangular corrugated plate stamped by a die. The advantage of this type is that the corrugated plate can provide a larger surface area under the same outer size, and the heat dissipation efficiency is significantly higher than the first type. But the defect is that the corrugated plate is a profile produced by die stamping, so its wall thickness is relatively thin (mostly 0.15-0.3 mm), which leads to the heat on the heat sink not being well conducted along the heat dissipation rib to the entire heat dissipation air duct, thereby affecting the heat dissipation efficiency of the heat sink.
[0027] Based on the above reasons, the present application provides the following embodiments.
[0028] Embodiment one:
[0029] As Figures 1-4 shown, this embodiment provides a heat dissipation plate 100, which comprises a frame 101 (optionally, the frame is rectangular), a plurality of heat dissipation main ribs 102 extending in a first direction are arranged in the frame, the first direction is the direction away from the heat source (as Figure 2 indicated by the arrow in the middle).
[0030] The two sides of adjacent heat dissipation main ribs have heat dissipation side branch ribs 103 which are inclined and extend in the first direction, and the heat dissipation side branch ribs extend to the adjacent heat dissipation main ribs or / and the lower part of the frame. Optionally, adjacent heat dissipation side branch ribs can be connected in the first direction by connecting ribs (as Figure 3 shown).
[0031] Optionally, the width of the heat dissipation main ribs and the heat dissipation side branch ribs gradually decreases in the first direction, and the average width of the heat dissipation main ribs is greater than the average width of the heat dissipation side branch ribs (as Figure 3 and Figure 4 shown). The heat dissipation plate is arranged in the first direction, and the upper end surface is a heat source mounting surface 104.
[0032] The above technical features improve the heat dissipation efficiency by interweaving a plurality of heat dissipation main ribs and heat dissipation side branch ribs to form a tree-shaped heat dissipation plate. The above technical features draw on the biological form of trees in nature. Tree roots absorb water and nutrient components in the earth, and then pass through thick trunks, main branches and side branches to finally reach the tree top. After millions of years of evolution, this set of transportation mode adopted by trees can make water and nutrient substances be absorbed by the tree body with extremely high transportation efficiency. Here, we can assume that "water and nutrient substances" are "heat flow", so the structure and morphology of the heat dissipation ribs can be equivalent to the morphology of the trees. The position close to the heat source is taken as the root of the heat dissipation rib, and the change rule from thick to thin (thick to thin) is followed to derive the main rib, the main branch rib and the side branch rib in turn, so that more heat at the root can be conducted to other positions through the main rib, thereby improving the heat dissipation efficiency.
[0033] In order to realize the processing of the heat dissipation plate, in an embodiment, the heat dissipation plate is integrally formed, and preferably, the heat dissipation plate is once formed by 3D printing.
[0034] Embodiment two, as Figure 3As shown, the embodiment provides a wind heat radiator, which is improved on the basis of a conventional wind heat radiator, specifically, the heat dissipation plate 100 is installed on at least one face of the heat dissipation frame 200 of the wind heat radiator, and the heat source installation plate 300 is installed on the upper end.
[0035] The above description of disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application. Therefore, the present application will not be limited to these embodiments shown herein, but will accord with the widest scope consistent with the principles and novel features disclosed herein.
