Description

Technical Field

[0001] The utility model relates to the technical field of heating wire brackets, in particular to an MOCVD heating wire bracket. Background Art

[0002] During the mass production of metal organic chemical vapor deposition (MOCVD), as the use time of the heating wire bracket increases, the pressure generated by the thermal expansion and contraction of the heating wire during the heating and cooling process causes the bracket to break. Under the same conditions, the heating bracket can be changed to a thicker bracket to increase the damage resistance.

[0003] Therefore, under the pressure generated by the thermal expansion and contraction of the supporting heating wire, the damage resistance of the heating wire bracket is increased, and the life of the heating wire bracket is improved.

[0004] Existing technical solutions:

[0005] Ordinary tungsten-rhenium heating wire brackets will deform and break after 1 to 2 months of use, which will cause the heating wire to deform and affect its life.

[0006] For this purpose, a MOCVD heating wire support is proposed. Utility Model Content

[0007] The purpose of the utility model is to solve the problems that the ordinary tungsten-rhenium heating wire bracket will deform and break after being used for 1-2 months, the service life is short, and the bracket has high cost. The utility model provides an MOCVD heating wire bracket.

[0008] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0009] A MOCVD heating wire bracket comprises a bracket main body. A plurality of protrusions are arranged on the top of the bracket main body. The protrusions are evenly arranged along the axial direction of the bracket main body.

[0010] Furthermore, the bracket body is "U"-shaped and made of tungsten potassium material.

[0011] Furthermore, the length of the bracket body is 33 mm.

[0012] Furthermore, the width of the bracket body is 23.3 mm.

[0013] The beneficial effects of the utility model are as follows:

[0014] The heating wire expands and contracts due to heat and cold, so the bracket is repeatedly subjected to the lateral shear stress of the heating wire. The high temperature causes damage to the bracket. The top of the modified tungsten potassium heating wire bracket is convex, the shape of the bracket and the thickness of the crossbeam are changed, the heat transfer between the bracket and the heating wire is reduced, and the bracket temperature is lowered, thereby increasing the service life of the bracket.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figure 1-2 As shown, a MOCVD heating wire bracket includes a bracket body 1, and a plurality of protrusions 2 are arranged on the top of the bracket body 1. The protrusions 2 are evenly arranged along the axial direction of the bracket body 1. The protrusions on the top of the heating wire bracket are designed to reduce the contact area with the heating wire, thereby reducing the temperature, reducing the stress caused by the heating wire's thermal expansion and contraction due to heating and cooling, and causing the bracket to deform and break.

[0023] Specifically, the stent body 1 is "U"-shaped and made of tungsten potassium material;

[0024] In this embodiment, the hardness of the bracket is improved by changing the material, appearance and shape of the bracket, thereby enhancing its compression resistance and damage resistance, and improving the service life of the heating wire bracket.

[0025] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
