[0027] Example 1

[0028] This embodiment provides a visual device for a temperature and humidity test chamber, the purpose of which is to solve the problem of fogging of the window glass in existing viewing windows during the test. (Refer to...) Figures 1-4 The specific structure of this embodiment will be described in detail below.

[0029] A visual device for a temperature and humidity test chamber includes an internally hollow main flange 1 and a window glass 2.

[0030] The main flange 1 has a hollow interior with a glass placement end face 11. The window glass 2 is placed on the glass placement end face 11 and fixed by the upper flange 3 that runs through the middle. A heating element 4 is provided between the window glass 2 and the hollow inner wall of the main flange 1.

[0031] In this embodiment, the main flange 1 is installed in a pre-drilled through-hole on the side wall of the temperature and humidity test chamber, providing a viewing window. The upper flange 3 secures the window glass 2 within the hollow interior of the main flange, creating a viewing area through the center of the upper flange 3. This allows observation of the interior of the temperature and humidity test chamber. Furthermore, if fogging occurs on the window glass 2, a heating element 4 can be used to heat the window glass 2 and eliminate the fogging, ensuring normal observation during reliability environmental testing. The heating element 4 can be attached to the hollow inner wall of the main flange 1.

[0032] Specifically, a flange placement surface 12 is provided at the hollow opening inside the main flange 1, and a plurality of first threaded holes 13 are evenly provided on the flange placement surface 12; a first through hole 31 that matches the first threaded hole 13 is provided on the upper flange 3, and the upper flange 3 and the main flange 1 are connected by bolts passing through the first through hole 31 and inserted into the first threaded hole 13 to fix the window glass 2.

[0033] In this embodiment, the upper flange 3 is a T-shaped flange with a through-hole in the middle. The diameter of the through-hole is the same as the diameter of the hollow interior of the main flange 1. Thus, the top of the upper flange 3 is attached to the flange placement surface 12, and the upper flange 3 and the main flange 1 are connected by bolts passing through the first through hole 31 and inserted into the first threaded hole 13, so that the bottom of the upper flange 3 contacts the window glass 2, thereby achieving the purpose of fixing the window glass 2.

[0034] Specifically, a first window sealing ring 32 is provided at the bottom of the upper flange 3. A second window sealing ring 14 is provided on the glass placement end face 11. The connection is sealed by the first window sealing ring 32 and the second window sealing ring 14.

[0035] Specifically, a cable groove 15 is provided in the middle of the side wall of the main flange 1, and an inlet port 16 is provided on the side wall of the main flange 1 located in the cable groove 15.

[0036] In this embodiment, after the main flange 1 is embedded in the mounting through hole of the side wall of the temperature and humidity test chamber, the side wall of the main flange 1 is tangent to the chamber wall of the temperature and humidity test chamber. A through groove 15 is provided in the middle of the side wall of the main flange 1. The connection line of the heating element 4 enters the inlet 16 through the through groove 15 and is electrically connected to the heating element 4, thereby controlling the heating element 4.

[0037] Specifically, multiple air holes 17 are evenly provided on the circumferential side wall of the main flange 1 located in the cable groove 15.

[0038] In this embodiment, the present invention provides an air blowing hole 17 in the through groove 15 of the main flange 1. The air blowing hole 17 is inclined on the side wall of the main flange 1 so as to face the window glass 2, so that dry nitrogen can pass through the chamber wall of the temperature and humidity test chamber and be sent into the air blowing hole 17. Then, the dry nitrogen is used to blow the window glass 2 through the inclined air blowing hole 17, and defrosting is performed when frost appears on the window glass 2.

[0039] Optionally, a venting groove 18 is provided at the bottom of the through groove 15 to fit the air blowing hole 17. The venting groove 18 facilitates better entry of dry nitrogen into the air blowing hole 17.

[0040] Specifically, the bottom of the main flange 1 is provided with a lower flange 5 that is through the middle and communicates with the internal hollow part of the main flange 1.

[0041] The bottom of the main flange 1 is evenly provided with multiple second threaded holes 19. The middle of the lower flange 5 is provided with a connecting platform 51. The connecting platform 51 is provided with a second through hole 52 that matches the second threaded holes 19. The lower flange 5 and the main flange 1 are connected by bolts passing through the second through hole 52 and inserted into the second threaded hole 19.

[0042] In this embodiment, after the main flange 1 is embedded in the mounting through hole of the side wall of the temperature and humidity test chamber, the side wall of the main flange 1 is tangent to the chamber wall of the temperature and humidity test chamber, the lower surface of the top of the main flange 1 is in contact with the outer side of the chamber wall of the temperature and humidity test chamber, and the lower flange 5 is inside the temperature and humidity test chamber. The lower flange 5 and the main flange 1 are connected by bolts passing through the second through hole 52 and inserted into the second threaded hole 19. The inner side of the bottom of the lower flange 5 is in contact with the inner side of the chamber wall of the temperature and humidity test chamber, thereby fixing the device in the mounting through hole of the side wall of the temperature and humidity test chamber.

[0043] The lower flange 5 is connected to the hollow interior of the main flange 1 through the middle to form a through window viewing area.

[0044] Optionally, flange sealing rings 53 are provided on the inner side of the top of the main flange 1 and the inner side of the bottom of the lower flange 5. The flange sealing rings 53 seal the connection between the inner side of the top of the main flange 1 and the inner side of the bottom of the lower flange 5 and the wall of the temperature and humidity test chamber.

[0045] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
