Description

Technical Field

[0001] The utility model relates to the technical field of PGU heat dissipation, in particular to a structure for enhancing the heat dissipation effect of a PGU. Background Art

[0002] PGU generates heat during operation. If the heat cannot be dissipated in a timely and effective manner, it may lead to device performance degradation, shortened lifespan, or even failure. Therefore, a good heat dissipation design is essential for the normal operation of PGU. The common heat dissipation method of PGU is to dissipate heat through a radiator. The larger the surface area of ​​the radiator and the more heat dissipation fins, the better the heat dissipation effect.

[0003] However, the existing PGU heat dissipation mainly relies on the radiator. In the AR-HUD's PGU, the part of the optical machine that generates heat when working only occupies a part of the entire area used for heat dissipation. The utilization rate of the heat dissipation fins in other non-heating areas is not high, which makes the heat dissipation effect of the radiator not good enough. Utility Model Content

The structure can not only increase the heat pipe to quickly transfer the heat in the heat-generating area to the fins in other areas for heat dissipation, thereby greatly improving the heat dissipation effect, but also allow the heat pipe to be quickly disassembled and installed, which is convenient for subsequent cleaning and recycling of the heat pipe.

[0018] Through the above technical solution, the first connecting shaft and the second connecting shaft will slide with the second connecting block during the movement, and the first connecting shaft can be limited by the second connecting block, so that the centers of the first positioning plate and the second positioning plate are located on the same vertical plane, thereby preventing the clamping surfaces of the first positioning plate and the second positioning plate from deviating from each other during the movement.

[0019] Furthermore, a support base is fixedly connected to the upper surface of the radiator, and the first connecting shaft and the second connecting shaft pass through the support base.

DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figure 1-Figure 4 The utility model provides a technical solution: a structure for enhancing the heat dissipation effect of a PGU, comprising a radiator 1, a fin 2 is arranged on one side of the radiator 1, a hole 3 is opened inside the fin 2, a heat pipe 4 is penetrated inside the hole 3, a thermal conductive silicone grease 5 is applied to the connection between the heat pipe 4 and the radiator 1, an optical machine 6 is installed on one side of the radiator 1, a thermal conductive pad 7 is arranged between the optical machine 6 and the radiator 1, the fins 2 are equidistantly distributed on one side of the radiator 1, the heat pipes 4 are equidistantly distributed on one side of the radiator 1, and the fins 2 and the heat pipes 4 are perpendicular to each other.

[0036] It is worth mentioning that the fins 2 can be connected to each other by using the heat pipe 4, and the connection between the heat pipe 4 and the radiator 1 is coated with thermal conductive silicone grease 5 to increase the contact area between the two, and the thermal pad 7 arranged between the optical engine 6 and the radiator 1 is made of thermal conductive silicone grease to improve the heat conduction efficiency between the optical engine 6 and the radiator 1, and the heat pipe 4 is made of copper and filled with heat conductive liquid. The heat in the heating area can be quickly transferred to the fins 2 in other areas through the heat pipe 4 for heat dissipation, thereby greatly improving the heat dissipation effect.

[0037] See also Figure 5 Figure 8 The two ends of the heat pipe 4 are respectively connected with a first positioning plate 8 and a second positioning plate 11, the first positioning plate 8 and the second positioning plate 11 are in a semicircular structure, and the first positioning plate 8 and the second positioning plate 11 are respectively tightly fitted with the heat pipe 4.

[0038] The function of the first positioning plate 8 and the second positioning plate 11 is to clamp the heat pipe 4 by means of the first positioning plate 8 and the second positioning plate 11, thereby positioning the heat pipe 4 so that the heat pipe 4 is stably connected to the fin 2, thereby ensuring that heat can be continuously, stably and efficiently transferred between the heat pipe 4 and the fin 2, and there will be no interruption of heat conduction or reduction in efficiency due to unstable connection.

[0039] See also Figure 1-Figure 8 The outer surface of the first positioning plate 8 is fixedly connected with a first connecting block 9, and a first connecting shaft 10 is passed through the interior of the first connecting block 9. The first connecting block 9 and the first connecting shaft 10 are connected in a fixed manner. The outer surface of the second positioning plate 11 is fixedly connected with a second connecting block 12, and a second connecting shaft 14 is passed through the interior of the second connecting block 12. The second connecting block 12 is connected in a fixed manner. A through hole 13 is opened inside the second connecting block 12, and the first connecting shaft 10 passes through the through hole 13. The first connecting shaft 10 and the second connecting block 12 are connected in a sliding manner. A support seat 16 is fixedly connected to the upper surface of the radiator 1, and the first connecting shaft 10 and the second connecting shaft 14 pass through the support seat 16. Sleeves 15 are connected to both ends of the first connecting shaft 10 and the second connecting shaft 14, respectively, and bolts 17 are connected to the interior of the sleeve 15;

[0040] The principle of being able to quickly disassemble and install the heat pipe 4 is as follows: when the heat pipe 4 needs to be connected to the fin 2, firstly, the heat pipe 4 is passed through the hole 3 so that the heat pipe 4 is tightly connected to the fin 2, and then the first connecting shaft 10 and the second connecting shaft 14 are pulled in different directions respectively, and the first connecting shaft 10 drives the plurality of first positioning plates 8 to move at the same time through the plurality of first connecting blocks 9, and the second connecting shaft 14 drives the plurality of second positioning plates 11 to move at the same time through the plurality of second connecting blocks 12, so that the first positioning plates 8 and the second positioning plates 11 clamp the heat pipe 4, and then the bolt 17 is rotated to make it threadedly connected with the sleeve 15, and the bolt 17 and the sleeve 15 are used to connect the heat pipe 4. The threaded connection can position the first connecting shaft 10 and the second connecting shaft 14, so that the first positioning plate 8 and the second positioning plate 11 can stably clamp the heat pipe 4. When the heat pipe 4 needs to be separated from the fin 2, the bolt 17 is first rotated to separate it from the sleeve 15 to release the positioning of the first connecting shaft 10 and the second connecting shaft 14. Then, the first connecting shaft 10 and the second connecting shaft 14 are pushed in different directions respectively, so that the first positioning plate 8 and the second positioning plate 11 are separated from the heat pipe 4 respectively. At this time, the positioning of the heat pipe 4 is released, and finally the heat pipe 4 can be pulled out from the inside of the fin 2, which is convenient for subsequent cleaning and recycling of the heat pipe 4.
