Abstract
Description
Technical Field
[0001] The utility model relates to a heat dissipation structure of a vehicle-mounted flat panel, in particular to a vehicle-mounted equipment cylindrical heat dissipation structure used for industrial and agricultural electronic products. Background Art
[0002] The heat sink of the vehicle-mounted flat panel used in mining, engineering machinery, agriculture, and roads is made of die-cast aluminum alloy with a thermal conductivity of only 96.2 (W / mK). In order to effectively conduct heat, the heat sink needs to occupy a considerable area of the entire machine, resulting in high costs for die-cast aluminum heat sinks. Metal parts will also shield RF signal transmission and reduce antenna efficiency.
[0003] Conventional heat sinks are integrally injection molded with the back shell, resulting in a high production defect rate. In addition, disassembly and after-sales repairs are difficult, which indirectly increases the cost of the heat sink. Summary of the invention
[0004] In order to solve the above technical problems, the utility model provides a cylindrical heat dissipation structure for vehicle-mounted equipment, which solves the problem of high cost of each vehicle-mounted flat heat dissipation component, simultaneously improves the thermal conductivity of the heat dissipation component, improves problems such as maintenance and disassembly, and reduces the cost of the heat dissipation component.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A cylindrical heat dissipation structure for vehicle-mounted equipment mainly consists of a display screen module, a front shell assembly, a mainboard assembly, a rear shell assembly, and a cylindrical heat dissipation component.
[0007] The cylindrical heat sink is located above the rear shell and is fixed by glue point sealing. The cylindrical heat sink is made of pure aluminum; the gap between the cylindrical heat sink and the plastic rear shell is fixed by glue point sealing for waterproofing.
[0008] Furthermore, the display screen module is located below the face shell assembly and is fixed and sealed by the face shell foam glue.
[0009] Furthermore, the mainboard assembly is located above the rear shell and is fixed by screws.
[0010] The cylindrical heat sink is machined by turning, and the machining process is simple. Compared with the die-cast aluminum alloy heat sink, there is no material loss, and the cost of a single piece is only 30% of that of the die-cast aluminum alloy heat sink.
[0011] The beneficial effects of the utility model are as follows: the cylindrical heat sink is made of pure aluminum, which increases the thermal conductivity of the heat sink, reduces the heat sink area of the entire machine, has low unit cost, and reduces costs and increases efficiency.
[0012] The cylindrical heat sink and the back shell are fixed by glue to prevent rainwater from penetrating into the interior of the tablet through the gap between the heat sink and the back shell, thereby improving the waterproof performance.
[0013] The cylindrical heat sink is easy, convenient and reliable to assemble, which can reduce production defects in the in-mold injection molding process and reduce the cost of project structural parts.
[0014] The cylindrical heat sink eliminates the fin structure, increasing the overall aesthetics of the vehicle-mounted product. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0027] like Figure 1 to Figure 2As shown, the whole machine assembly process is described as follows: Assemble the display screen module 200 to the face shell assembly 100, and keep the jig under pressure for 15S. Then assemble the cylindrical heat sink 500 to the rear shell assembly 400 and fix it with glue. Then assemble the mainboard assembly 300 to the rear shell assembly 400 and fix it with screws. Finally, install the face shell assembly 100 with the display screen module 200 assembled to the rear shell assembly 400 and fix it with screws, thus completing the whole machine structure assembly of the vehicle-mounted tablet 001.
[0028] like Figures 2 to 6 As shown, two cylindrical heat sinks 500 are located above the rear shell assembly 400. The platform 510 is supported by the cylindrical heat sink 500 and installed in the CPU module slot 411 and the 5G module slot 421 of the rear shell assembly 400 respectively, and then fixed with hot melt glue.
[0029] like Figures 2 to 6 As shown, the motherboard assembly 300 is located above the rear shell assembly 400 and is fixed by screws. The CPU module 310 and the 5G module 320 on the motherboard assembly 300 are respectively in contact with the heat-conducting plane 520 of the cylindrical heat sink 500, and the gap in the middle is filled with thermally conductive silicone.
[0030] like Figures 2 to 6 As shown, the heat source of the high power consumption device of the mainboard assembly 300, the CPU module 310 and the 5G module 320 is directly introduced into the air through two cylindrical heat sinks 500, thereby achieving rapid heat conduction. Glue is dispensed in the CPU module frame 412 and the 5G module frame 422 of the rear shell assembly 400 to form a waterproof sealed closed loop, thereby preventing rainwater from penetrating from the heat sink and the rear shell area.
[0031] like Figure 5 and Figure 6 As shown, the cylindrical heat sink 500 is made of pure aluminum, and the thermal conductivity is increased from die-cast aluminum alloy / 96.2 (W / mK) to 210 W (m·K), which improves the heat conduction efficiency of the heat sink, thereby reducing the heat sink area and reducing the heat sink cost. The cylindrical heat sink 500 support platform 510 is turned, and the processing technology is simple. Compared with the die-cast aluminum alloy heat sink, there is no material loss, and the unit cost is only 30% of the die-cast aluminum alloy heat sink.
[0032] like Figure 1 and Figure 6 As shown, the cylindrical heat sink 500 and the rear shell assembly 400 form a boss to reduce contact with the external bracket, improve the overall heat dissipation performance, and improve external impact stress.
[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
