Description

Technical Field

[0001] The utility model belongs to the technical field of ultraviolet imagers, and in particular relates to a heat dissipation structure of an ultraviolet imager. Background Art

[0002] The ultraviolet imagers currently on the market can easily cause heating during high-frequency focusing and adjustment. At the same time, since the product is used outdoors for a long time, especially when it replaces infrared thermal imagers for inspections in hot summer weather, the ambient temperature is too high and the product itself has a low heat dissipation capacity, it is difficult to ensure long-term outdoor use of the product.

[0003] The existing ultraviolet imager achieves heat dissipation by setting a metal heat sink and heat dissipation pores, but the heat dissipation effect is poor. The internal lens of the ultraviolet imager will continuously generate a large amount of heat due to work, which makes the local temperature of the ultraviolet imager high and prone to failure.

[0004] Therefore, a heat dissipation structure of an ultraviolet imager is proposed. Utility Model Content

[0007] Preferably, the hollow copper tube passes through a through hole, and the interior of the through hole is filled with heat dissipation silica gel.

[0008] Preferably, there are twenty through holes in total, and the twenty through holes are distributed in a ring shape around the outer side of the lens.

[0009] Preferably, the guide hole is communicated with the inner space of the hollow copper tube.

[0010] Preferably, the guide platform is a cone structure.

[0011] Preferably, a through hole for a nut to pass through is provided on an outer wall of the mounting plate on a side away from the ultraviolet imager.

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present utility model embodiment provides a heat dissipation structure of an ultraviolet imager, such as Figure 1-5 As shown, it includes an ultraviolet imager 1, a lens 2 is embedded on one side outer wall of the ultraviolet imager 1, and a through hole 3 is provided on one side outer wall of the ultraviolet imager 1 near the outer side of the lens 2, and a total of twenty through holes 3 are arranged, and the twenty through holes 3 are distributed in a ring shape around the outer side of the lens 2, and a mounting plate 4 is fixedly connected to the inner side of the through hole 3 on one side outer wall of the ultraviolet imager 1 through a nut, and a through hole for the nut to penetrate is provided on the side outer wall of the mounting plate 4 away from the ultraviolet imager 1, and a hollow copper tube 5 is welded on one side of the outer wall of the mounting plate 4 near the through hole 3. A heat dissipation silicone filling groove 6 is opened on the outer wall of one side of the core copper tube 5, an outer protective cover 7 is fixedly connected to the outer side of the mounting plate 4 on the outer wall of one side of the ultraviolet imager 1 by bolts, a filter screen 8 is embedded in the central position of the outer wall of the outer protective cover 7 away from the ultraviolet imager 1, a fan 9 is fixedly connected to the inner central position of the outer protective cover 7 by bolts, a guide platform 10 is welded at the central position of the outer wall of one side of the mounting plate 4, and a through guide hole 11 is opened on the outer wall of one side of the mounting plate 4 near the side of the hollow copper tube 5, and the guide hole 11 is connected to the internal space of the hollow copper tube 5.

[0023] It should be noted that, since the existing ultraviolet imager realizes the heat dissipation function by setting a metal heat sink and heat dissipation pores, the heat dissipation effect is poor, and the lens inside the ultraviolet imager will continue to generate a large amount of heat due to work, which will cause the local temperature of the ultraviolet imager to be high and prone to failure. This embodiment can effectively dissipate the internal heat of the ultraviolet imager 1 by penetrating the circumference of the hollow copper tube 5 arranged around the outside of the lens 2 inside the ultraviolet imager 1, and utilize the flow of convection air in the hollow copper tube 5, so as to achieve efficient heat dissipation, avoid the problem of high local temperature near the lens 2 inside the ultraviolet imager 1 affecting the working stability of the ultraviolet imager 1, and avoid the ultraviolet imager 1 from malfunctioning due to high temperature.

[0024] Specifically, in this embodiment, this scheme mainly includes a hollow copper tube 5. When in use, heat dissipation silica gel is filled in the through hole 3, and the hollow copper tube 5 is inserted into the through hole 3. The heat dissipation silica gel is filled in the heat dissipation silica gel filling groove 6 opened on the outer wall of the hollow copper tube 5. When the hollow copper tube 5 is completely inserted into the through hole 3, the mounting plate 4 and the ultraviolet imager 1 are fastened, and the heat dissipation silica gel inside the hollow copper tube 5 is pushed out by a rod-shaped tool (not shown in the figure), so as to clean the heat dissipation silica gel inside the hollow copper tube 5 and ensure that the hollow copper tube 5 is unobstructed. When the ultraviolet imager 1 is working, the ultraviolet imager 1 The temperature of the outer side of the interior near the lens 2 is high, and the heat is transferred to the hollow copper tube 5. At this time, the fan 9 is powered on and works, and the fan 9 works to blow the airflow to the guide platform 10. Under the guidance of the guide platform 10, the air passes through the guide hole 11 and enters the hollow copper tube 5. The air flows inside the hollow copper tube 5. Through the heat exchange between the air and the hollow copper tube 5, the heat in the hollow copper tube 5 is transferred to the air, and the hot air is discharged from the hollow copper tube 5, so as to realize the heat dissipation of the ultraviolet imager 1 and avoid the problem that the local high temperature near the lens 2 inside the ultraviolet imager 1 affects the working stability of the ultraviolet imager 1.

[0025] In a further preferred embodiment of the present invention, Figure 1 As shown, the hollow copper tube 5 passes through the through hole 3, and the interior of the through hole 3 is filled with heat dissipation silica gel.

[0026] In this embodiment, the hollow copper tube 5 is in close contact with the through hole 3 through the heat dissipation silica gel, thereby enabling efficient heat transfer in the ultraviolet imager 1 .

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, the guide platform 10 is a cone structure.

[0028] In this embodiment, the conical guide platform 10 can evenly guide the air to the guide holes 11 , thereby allowing the air to enter the hollow copper tube 5 .
