Description

Technical Field

[0001] This utility model belongs to the field of aircraft projector technology, specifically relating to a high-efficiency heat dissipation aluminum alloy housing for projectors. Background Technology

[0002] With the ever-increasing demand for large-screen displays and the rapid advancement of smart technology, projectors have been widely used in home entertainment, business offices, education, and aviation. Among the many components of a projector, the casing is a crucial part that protects internal precision components, affects heat dissipation efficiency, and determines the product's appearance and texture. Therefore, the choice of materials for the casing is of paramount importance. Effective heat dissipation from the casing is key to ensuring the stable operation of the projector's internal optical and electronic components, preventing problems such as image quality degradation and equipment malfunctions caused by overheating.

[0003] Existing projector housings typically consist of an aluminum alloy shell assembled from a left side panel, a right side panel, a front side panel, and a rear side panel, along with a top cover and a bottom plate. While this method ensures the flatness of the shell, the aluminum alloy shell requires assembly, which is inconvenient. Furthermore, the flat surface makes it difficult to dissipate heat under high load conditions when installed in an aircraft, leading to high temperature alarms and performance degradation. Therefore, a projector aluminum alloy shell with high-efficiency heat dissipation is proposed. Utility Model Content

This housing is designed to solve the problem that the aluminum alloy housing of the existing projector needs to be assembled, which is not only inconvenient to assemble, but also difficult to meet the heat dissipation requirements of the projector under high load conditions.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a high-efficiency heat dissipation aluminum alloy housing for a projector. The housing includes an aluminum profile outer frame, with cross-shaped reinforcing ribs fixedly connected between the inner walls of the aluminum profile outer frame. Four first protrusions are fixedly connected to the upper surface of the aluminum profile outer frame, four second protrusions are fixedly connected to the lower surface of the aluminum profile outer frame, and two third protrusions are fixedly connected to the right side of the aluminum profile outer frame. The upper surface of the aluminum profile outer frame is bent upward to form a boss. Multiple first heat dissipation fins are fixedly connected to the upper surface of the aluminum profile outer frame and between the two first protrusions on the right side. Multiple second heat dissipation fins and third heat dissipation fins are fixedly connected to the lower surface of the aluminum profile outer frame and between the three second protrusions on the left side.

[0008] Preferably, the cross-shaped reinforcing rib includes horizontal ribs and vertical ribs. The horizontal ribs are fixedly connected to the inner walls of the left and right sides of the aluminum profile outer frame. There are three vertical ribs. The left and right vertical ribs are fixedly connected to the inner walls of the upper and lower sides of the aluminum profile outer frame. The middle vertical rib is fixedly connected to the inner wall of the boss and the lower inner wall of the aluminum profile outer frame.

[0009] Furthermore, the horizontal and vertical ribs have the same thickness, while the thickness of the aluminum profile outer frame is greater than the thickness of the horizontal and vertical ribs.

[0010] Furthermore, the upper surface of the boss is set parallel to the upper surface of the aluminum profile outer frame, and the bends on the left and right sides of the boss coincide with the two first protrusions in the middle.

[0011] Furthermore, the first, second, and third protrusions are all arc-shaped structures, and mounting holes are provided on each of the first, second, and third protrusions.

[0012] Furthermore, the number of the first and second heat dissipation fins are both nine, and the number of the third heat dissipation fins is twelve. The third and fourth fins on the left side of the first and second heat dissipation fins are recessed into the interior of the other fins.

[0013] Furthermore, a heat-conducting plate is attached to the left side of the aluminum profile frame with thermally conductive adhesive. Threaded grooves are provided at the four corners of the left side of the aluminum profile frame. The four corners of the heat-conducting plate are connected to the threaded grooves by screws.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features an integrally molded aluminum profile outer frame with cross-shaped reinforcing ribs to prevent deformation during processing. Furthermore, a first heat dissipation fin, a second heat dissipation fin, and a third heat dissipation fin are provided on the outer side of the aluminum profile outer frame. Utilizing the excellent heat absorption effect of the aluminum profile, heat is quickly absorbed and conducted to the fins for heat dissipation, thereby improving heat dissipation efficiency and preventing high temperature alarms and performance degradation in the projector.

[0017] 2. This utility model, by setting a detachable heat-conducting plate and heat-conducting teeth, allows for selective installation of a heat dissipation structure. Utilizing the excellent thermal conductivity of thermal grease, the heat absorbed by the heat-conducting plate from the aluminum profile outer frame is dissipated, and then the heat is dissipated by multiple heat-conducting teeth. This further improves the heat dissipation effect of the projector, making the aluminum profile outer frame better suited for projectors with higher power. Attached Figure Description

[0025] This specific embodiment is a high-efficiency heat dissipation aluminum alloy housing for a projector, and its structural schematic diagram is shown below. Figures 1-6 As shown, the housing includes an aluminum profile outer frame 1. Cross reinforcing ribs 2 are fixedly connected between the inner walls of the aluminum profile outer frame 1. Four first protrusions 3 are fixedly connected to the upper surface of the aluminum profile outer frame 1. Four second protrusions 4 are fixedly connected to the lower surface of the aluminum profile outer frame 1. Two third protrusions 5 are fixedly connected to the right side of the aluminum profile outer frame 1. The upper surface of the aluminum profile outer frame 1 is bent upward to form a boss 6. Multiple first heat dissipation fins 7 are fixedly connected to the upper surface of the aluminum profile outer frame 1 and between the two first protrusions 3 on the right side. Multiple second heat dissipation fins 8 and third heat dissipation fins 9 are fixedly connected to the lower surface of the aluminum profile outer frame 1 and between the three second protrusions 4 on the left side. The heat dissipation fins can increase the contact area with air, so that the aluminum profile outer frame 1 can dissipate heat better.

[0026] like Figure 1 and Figure 2As shown: In this embodiment, the cross-shaped reinforcing rib 2 includes horizontal ribs 201 and vertical ribs 202. The horizontal ribs 201 are fixedly connected to the inner walls of the left and right sides of the aluminum profile outer frame 1. There are three vertical ribs 202. The left and right vertical ribs 202 are fixedly connected to the inner walls of the upper and lower sides of the aluminum profile outer frame 1, and the middle vertical rib 202 is fixedly connected to the inner wall of the boss 6 and the lower inner wall of the aluminum profile outer frame 1. The horizontal ribs 201 and vertical ribs 202 have the same thickness, and the thickness of the aluminum profile outer frame 1 is greater than the thickness of the horizontal ribs 201 and vertical ribs 202. During processing, the cross-shaped reinforcing rib 2 ensures that the aluminum profile outer frame 1 will not deform during processing and ensures the flatness of the aluminum profile outer frame 1.

[0027] like Figure 2 and Figure 3 As shown: In this embodiment, the upper surface of the boss 6 is parallel to the upper surface of the aluminum profile outer frame 1, and the bends on the left and right sides of the boss 6 coincide with the two first protrusions 3 in the middle.

[0028] like Figure 1 and Figure 3 As shown: In this embodiment, the first protrusion 3, the second protrusion 4 and the third protrusion 5 are all arc-shaped structures, and mounting holes 10 are provided on the first protrusion 3, the second protrusion 4 and the third protrusion 5; in this way, the upper cover plate and the lower bottom plate of the projector shell are fixed in the mounting holes 10 by screws and are fixed together with the aluminum profile outer frame 1.

[0029] like Figure 1 and Figure 2 As shown: In this embodiment, there are nine first heat dissipation fins 7 and nine second heat dissipation fins 8, and twelve third heat dissipation fins 9. The third and fourth fins on the left side of the first heat dissipation fins 7 and the second heat dissipation fins 8 are recessed into the interior of the other fins. The third and fourth fins on the left side have different heights, and the resulting grooves can avoid other components and reduce the overall volume.

[0030] like Figure 4-6 As shown: In this embodiment, a heat-conducting plate 11 is attached to the left side of the aluminum profile outer frame 1 with thermally conductive adhesive. Threaded grooves 14 are provided at the four corners of the left side of the aluminum profile outer frame 1. The four corners of the heat-conducting plate 11 are threaded into the threaded grooves 14 by screws 12. Multiple heat-conducting teeth 13 are fixedly connected to the left side of the heat-conducting plate 11, increasing the contact area with air. By setting a detachable heat-conducting plate 11 and heat-conducting teeth 13, a heat dissipation structure can be selectively installed. The excellent thermal conductivity of the thermal grease allows the heat absorbed by the heat-conducting plate 11 of the aluminum profile outer frame 1 to be conducted out, and then dissipated by the multiple heat-conducting teeth 13. This further improves the heat dissipation effect of the projector, making the aluminum profile outer frame 1 better suited for projectors with higher power.

[0031] Working principle: By setting an integrally molded aluminum profile outer frame 1, the cross reinforcing ribs 2 ensure that the aluminum profile outer frame 1 will not deform during processing, ensuring the flatness of the aluminum profile outer frame 1. Then, mounting holes 10 are opened on the first protrusion 3, the second protrusion 4, and the third protrusion 5. The middle cross reinforcing ribs 2 are all milled off using CNC. At this time, the middle of the aluminum profile outer frame 1 is hollow. The upper cover plate and the lower base plate of the projector shell are fixed in the mounting holes 10 with screws. During use, because the first heat dissipation fins 7, the second heat dissipation fins 8, and the third heat dissipation fins 9 are set on the outside of the aluminum profile outer frame 1, the excellent heat absorption effect of the aluminum profile is used to quickly absorb the heat and conduct the heat to the fins for heat dissipation, thereby improving the heat dissipation efficiency and avoiding the projector from high temperature alarms and performance degradation.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
