Title: Heat dissipation member

Description:
TECHNICAL FIELD 
     The disclosure relates to a heat dissipation member, and in particular, to a wall-mounted heat dissipation member. 
     BACKGROUND 
     Referring to  FIG.  1    and  FIG.  2    together,  FIG.  1    and  FIG.  2    are respectively a three-dimensional schematic view and a top view of a conventional heat dissipation member. The conventional heat dissipation member A includes a base plate A 1  and a plurality of fins A 2 . Each fin A 2  is vertically arranged on a wide side surface A 11  of the base plate A 1 . The each fin A 2  is substantially a rectangular sheet structure, and the fins A 2  are arranged on the base plate A 1  in parallel with each other. An airflow channel A 3  is formed between the fins A 2  adjacent to each other. 
     When the heat dissipation member A is fixed to a to-be-dissipated member in a form of wall hanging (that is, the wide side surface A 11  of the base plate A 1  is substantially perpendicular to the ground), a wide side surface A 21  of the each fin A 2  and the wide side surface A 11  of the base plate A 1  jointly limit a direction of air flow, and air can only move along a path P that is substantially perpendicular to the ground. Therefore, heat energy is easily accumulated in a region B shown in the figure, causing a poor overall heat dissipation effect of the heat dissipation member A. 
     SUMMARY 
     The disclosure discloses a heat dissipation member. The heat dissipation member is mainly configured to alleviate a problem that in the conventional heat dissipation member, heat energy is easily accumulated in a local region of the heat dissipation member, causing a poor overall heat dissipation effect of the heat dissipation member. 
     An embodiment of the disclosure discloses a heat dissipation member, including a base plate, a plurality of first sheet structures, and a plurality of second sheet structures. The base plate includes a first side edge and a second side edge that are not adjacent. Each first sheet structure is vertically arranged on the base plate. One end of the each first sheet structure is arranged adjacent to the first side edge. A spacing between two adjacent first sheet structures gradually increases from the first side edge to the second side edge, and an other end of a part of the first sheet structures is arranged adjacent to a third side edge of the base plate. The third side edge is adjacent to the first side edge. One end of each second sheet structure is arranged between the two adjacent first sheet structures. 
     Based on the above, through design of the plurality of first sheet structures and the plurality of second sheet structures, the heat dissipation member of the disclosure can effectively alleviate the problem that the conventional heat dissipation member is prone to heat energy accumulation, and can effectively improve the overall heat dissipation effect of the heat dissipation member.

     DETAILED DESCRIPTION 
     In the following description, if “refer to a specific drawing” or “as shown in a specific drawing” is indicated, it is only used to emphasize that in a subsequent description, most of the related content mentioned is shown in the specific drawing, but does not limit that reference can only be made to the specific drawing in the subsequent description. 
     Referring to  FIG.  3    to  FIG.  5    together,  FIG.  3    to  FIG.  5    are respectively a schematic three-dimensional view, a top view, and a schematic diagram of air flow of a first embodiment of a heat dissipation member according to the disclosure. The heat dissipation member  1  of the disclosure includes a base plate  11 ,  13  first sheet structures  12 , and  6  second sheet structures  13 . The base plate  11  may be, for example, a rectangular sheet structure. Four side edges of the base plate  11  may be respectively defined as a first side edge  111 A, a second side edge  111 B, a third side edge  111 C, and a fourth side edge  111 D. The first side edge  111 A is not adjacent to the second side edge  111 B, and the first side edge  111 A and the second side edge  111 B are located opposite to each other. The third side edge  111 C and the fourth side edge  111 D are located opposite to each other, and the first side edge  111 A is arranged adjacent to the third side edge  111 C and the fourth side edge  111 D. An appearance and a size of the base plate  11  are not limited to those shown in the drawings. 
     Each first sheet structure  12  is vertically arranged on a side surface  111  of the base plate  11 . One end of the each first sheet structure  12  is arranged adjacent to the first side edge  111 A. An other end of a part of the first sheet structures  12  is arranged adjacent to the second side edge  111 B. An other end of a part of the first sheet structures  12  is adjacent to the third side edge  111 C, and an other end of an other part of the first sheet structures  12  is arranged adjacent to the fourth side edge  111 D. As shown in  FIG.  4   , in the top view of the heat dissipation member  1 , a spacing between two adjacent first sheet structures  12  gradually increases from the first side edge  111 A to the second side edge  111 B. A minimum spacing between the two adjacent first sheet structures  12  is defined as a preset spacing L 1 . In a specific embodiment, the minimum spacing between any two adjacent first sheet structures  12  is the same. That is to say, all preset spacings L 1  shown in  FIG.  4    are the same. 
     Each second sheet structure  13  is arranged between two adjacent first sheet structures  12 . A minimum spacing L 3  between one end of the each second sheet structure  13  and an adjacent first sheet structure  12  is not greater than twice the preset spacing L 1 . Preferably, the minimum spacing L 3  between one end of the each second sheet structure  13  and the adjacent first sheet structure  12  is approximately the same as the preset spacing L 1 , and a minimum spacing L 2  between the two first sheet structures  12  adjacent to one end of the each second sheet structure  13  is approximately equal to twice the preset spacing L 1 . That is to say, one second sheet structure  13  is arranged at a position at which a spacing between the two adjacent first sheet structures  12  is greater than or equal to twice the preset spacing L 1 . An other end of the each second sheet structure  13  is arranged adjacent to the second side edge  111 B of the base plate  11 , which is not limited thereto. In different embodiments, an other end of a part of the second sheet structures  13  may alternatively be arranged adjacent to the third side edge  111 C or the fourth side edge  111 D. In addition, the spacing between the each second sheet structure  13  and any of the adjacent first sheet structures  12  gradually increases from the first side edge  111 A to the second side edge  111 B. 
     A number of the first sheet structures  12  and a number of the second sheet structures  13  included in the heat dissipation member  1  are not limited to those shown in the figures. The number of the second sheet structures  13  is mainly related to the size of the base plate  11  and the number of the first sheet structures  12 . In practical application, the base plate  11 , the each first sheet structure  12 , and the each second sheet structure  13  may be integrally formed by using the die casting technology. 
     Based on the above, as shown in  FIG.  3    to  FIG.  5   , the heat dissipation member  1  of the disclosure is designed through the plurality of first sheet structures  12  and the plurality of second sheet structures  13 . In this way, when the heat dissipation member  1  is arranged on a to-be-dissipated device in a form of wall hanging (that is to say, the side surface  111  of the base plate  11  is arranged substantially perpendicular to the ground, and the first side edge  111 A of the base plate  11  is arranged adjacent to the ground), part of air may enter the heat dissipation member  1  from the first side edge  111 A of the base plate  11  along a first path P 1 , and flow out of the heat dissipation member  1  from the third side edge  111 C or the fourth side edge  111 D. Therefore, heat energy can disperse from the heat dissipation member  1  relatively quickly. Another part of the air can first flow into the heat dissipation member  1  along a second path P 2 , and then flow out of the heat dissipation member  1  along a third path P 3 . In this way, the problem that the heat energy is accumulated at a middle position of the heat dissipation member  1  can be effectively alleviated, thereby effectively improving the overall heat dissipation effect of the heat dissipation member  1 . 
     Referring to  FIG.  3    to  FIG.  6    together,  FIG.  6    shows a top view of a heat dissipation member. Each first sheet structure and each second sheet structure shown in  FIG.  6    are represented as an orthographic projection of each first sheet structure  12  on the side surface  111  of the base plate  11  and an orthographic projection of each second sheet structure  13  on the side surface  111  of the base plate  11 . In a preferred embodiment, an included angle  01  between an orthographic projection of the first sheet structure  12 B closest to the third side edge  111 C on the side surface  111  of the base plate  11  and an orthographic projection of the first sheet structure  12 A at a central position of the first side edge  111 A on the side surface  111  is  45  degrees. An included angle  02  between an orthographic projection of the first sheet structure  12 D closest to the fourth side edge  111 D on the side surface  111  and an orthographic projection of the first sheet structure  12 A at a central position of the first side edge  111 A on the side surface  111  is 45 degrees. An included angle between an orthographic projection of each of the first sheet structures  12 C 1 - 12 C 5  away from the central position of the first side edge  111 A on the side surface  111  and an orthographic projection of the first sheet structure  12 A at the central position of the first side edge  111 A on the side surface  111  of the base plate  11  is between 5 degrees and 45 degrees. An included angle between an orthographic projection of each second sheet structure  12  on the side surface  111  and an orthographic projection of an adjacent first sheet structure  12  on the side surface is between 5 degrees and 10 degrees. Two included angles between the orthographic projection of the second sheet structure  12  on the side surface  111  and orthographic projections of two first sheet structures  12  on two adjacent sides on the side surface  111  are equal. 
     Carrying on with the above, for example, included angles θ 3 -θ 7  between orthographic projections of the first sheet structures  12 C 1 - 12 C 5  shown in  FIG.  6    on the side surface  111  and orthographic projections of the first sheet structure  12 A on the side surface  111  are between 5 degrees and 45 degrees. Included angles θ 8 -θ 13  between orthographic projections of the second sheet structures  13 A- 13 C on the side surface  111  and two first sheet structures  12 A and  12 C 1 - 12 C 3  on two adjacent sides on the side surface are between 5 degrees and 10 degrees. The included angles θ 8  and θ 9  are equal, the included angles θ 10  and θ 11  are equal, and the included angles θ 12  and θ 13  are equal. Through the design of the foregoing included angles, the heat dissipation effect of the heat dissipation member  1  when hung on a to-be-dissipated member may further be improved. 
     Referring to  FIG.  7   ,  FIG.  7    shows a top view of a second embodiment of a heat dissipation member according to the disclosure. A difference between this embodiment and the above embodiments lies in that an avoidance notch  11 A is further formed on the first side edge  111 A of the base plate  11 , and the first side edge  111 A of the base plate  11  is partitioned into two transverse sections  111 A 1  and two longitudinal sections  111 A 2 . The heat dissipation member  1  is configured to be vertically hung on a to-be-dissipated electronic device, and the avoidance notch  11 A is configured to accommodate a protruding structure of the electronic device. In other words, an appearance and a size of the avoidance notch  11 A are designed according to an appearance and a size of the protruding structure of the electronic device, and the appearance and the size of the avoidance notch  11 A shown in the figure are only examples. 
     One ends of four first sheet structures  12  are arranged adjacent to one transverse section  111 A 1  of the first side edge  111 A. One ends of seven first sheet structures  12  are arranged adjacent to one transverse section  111 A 1  of the first side edge  111 A, and other four first sheet structures  12  are arranged adjacent to another transverse section  111 A 1  of the first side edge  111 A. In the drawings of this embodiment, one end of the each first sheet structure  12  is arranged only adjacent to one transverse section  111 A 1 , and one end of the each first sheet structure  12  is not arranged adjacent to any longitudinal section  111 A 2  by way of example, which is not limited thereto. In different embodiments, at least one first sheet structure  12  may alternatively be arranged adjacent to one longitudinal section  111 A 2 . 
     In addition, a preset spacing L 4  (L 5 , L 6 ) among the plurality of first sheet structures  12  adjacent to a same transverse section  111 A 1  may be exactly the same, and the preset spacings L 4 , L 5 , and L 6  among the plurality of first sheet structures adjacent to different transverse sections  111 A 1  may not be exactly the same. 
     Based on the above, when the heat dissipation member of the disclosure is arranged on the to-be-dissipated electronic device in the form of wall hanging, the heat energy is relatively not easily accumulated at the middle position of the heat dissipation member, and the heat dissipation member has a better overall heat dissipation effect. 
     The above are only preferred feasible embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural changes made based on the contents of the specification and the drawings of the present invention shall all fall within the protection scope of the present invention.
