[0041] The technical solutions in the embodiments will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0044] In the description of the present application, it needs to be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] In one illustrative embodiment of the assembled quartz lamp heater of the present application, the assembled quartz lamp heater is composed of a plurality of first heating modules 1 and second heating modules 2, which are two core components of the assembled quartz lamp heater of the present application. The two modules will be described in detail as follows:

[0046] Attached Figures 1-2 is the overall structure schematic diagram (simplified view) of the first heating module 1 in this assembled quartz lamp heater, from which it can be seen that the first heating module 1 includes a quartz lamp tube 3 and a first tube seat 4 arranged at the upper and lower ends of the lamp head of the quartz lamp tube 3, and the quartz lamp tube 3 and the first tube seat 4 are fixedly connected by screwing. Figure 3 is the overall structure schematic diagram (simplified view) of the second heating module 2 in this assembled quartz lamp heater, which is similar in overall structure to the first heating module 1. The second heating module 2 specifically includes a quartz lamp tube 3 and a second tube seat 5 arranged at the upper and lower ends of the lamp head of the quartz lamp tube 3, and the quartz lamp tube 3 and the second tube seat are also fixedly connected by screwing. It needs to be supplemented that, in combination with Figure 4The difference between the first tube seat 4 and the second tube seat 5 is that the included angle β between the axis 6 and its left / right mounting edge 8 is different. That is, when the included angle β between the axis 6 and its left / right mounting edge 8 is 0°, the first tube seat 4 is formed, and its cross-sectional view is shown in the attached figure. Figure 5 As shown; when the included angle β between axis 6 and its left / right mounting edge 8 is 10°, a second pipe seat 5 is formed, and its cross-sectional view is shown in the attached figure. Figure 6 As shown.

[0047] Furthermore, both the first tube seat 4 and the second tube seat 5 are integrally shaped like an I-beam or a square prism. For example, in the attached... Figure 1 In the provided first heating module 1, the first tube seat 4 at the upper end of the quartz lamp tube 3 is a square prism shape, and the first tube seat 4 at the lower end is an I-shaped shape; in the attached... Figure 2 In the first heating module 1 provided, both the upper and lower first tube bases 4 of the quartz lamp tube 3 are square prisms. The overall shape of the second tube base 5 connecting the upper and lower ends of the quartz lamp tube 3 in the second heating module 2 can also be referenced in the appendix. Figures 1-2 The components are assembled in the form of... However, it should be further noted that the first tube seat 4 in the first heating module 1 and the second tube seat 5 in the second heating module 2 are not limited to... Figures 1-3 These assembly forms can be selected or combined by those skilled in the art in the form of an I-shape or a square prism according to actual needs. These contents do not depart from the spirit of the technical solution of the present invention, and should all be covered within the scope of the technical solution claimed by the present invention.

[0048] Next, from the appendix Figures 5-6 As can be seen from the diagram, both the first tube seat 4 and the second tube seat 5 include a tube seat body 7 and mounting edges 8 disposed on the left and right sides of the tube seat body 7. The upper and lower ends of the lamp head of the quartz lamp tube 3 are fixedly connected to the sides of the tube seat body 7 by screws. The connection between the left and right mounting edges 8 of the first tube seat 4 and the second tube seat 5 is achieved through the fastening connection, thereby realizing the connection between multiple first heating modules 1 and second heating modules 2, forming as shown in the attached diagram. Figure 8 The diagram shows densely arranged quartz lamp heating strips 11. Specifically, a cylindrical cavity structure is provided inside the tube seat body 7 along the axis 6. This cavity structure serves as a cooling channel 9, through which coolant flows. The coolant flows along the cooling channel 9 to cool the first tube seat 4 and the second tube seat 5. The coolant used in this invention includes, but is not limited to, cooling water. (See attached diagram.) Figure 7 The diagram shows the structure of the mounting edge 8 for the first tube seat 4 or the second tube seat 5. As can be seen from the diagram, the mounting edge 8 is quadrilateral (or square) and has bolt holes 10 evenly distributed around its perimeter for fastening connections. These bolt holes 10 enable the fastening connection between the left and right mounting edges 8 of the first tube seat 4 and the second tube seat 5, thereby achieving the connection between multiple first heating modules 1 and second heating modules 2, ultimately resulting in the structure shown in the attached diagram. Figure 8The densely arranged quartz lamp heating strips 11 are shown.

[0049] In addition, the present invention provides a sealing gasket between two adjacent mounting edges 8, which is tightened and deformed by bolts to achieve a seal, preventing cooling water leakage. This allows the cooling water to flow along the cooling channel 9 to cool the first tube seat 4 and the second tube seat 5, preventing the heat radiated by the quartz lamp tube 3 from causing the first tube seat 4 and the second tube seat 5 to soften and creep, further improving the lifespan of the assembled quartz lamp heater.

[0052] (2) According to the pre-designed connection scheme, the heating modules are connected together by fastening the left and right mounting edges 8 of the first tube seat 4 and the second tube seat 5, and sealing gaskets are set between two adjacent mounting edges 8, thereby assembling multiple units as shown in the attached figure. Figure 8 The quartz lamp heating strip 11 is shown.

[0053] (3) Based on the shape characteristics of the test piece, multiple quartz lamp heating strips 11 are selectively placed vertically or horizontally, and two adjacent quartz lamp heating strips 11 are fixedly connected to obtain a quartz lamp heating combination array. Finally, the multiple connected quartz lamp heating strips 11 are arranged around the outer periphery of the test piece to achieve heating of the test piece.

Following this sequence, the heating modules are connected together through the fastening connection between the left and right mounting edges 8 of the first tube seat 4 and the second tube seat 5, forming a densely arranged quartz lamp heating strip 11. Furthermore, the invention also includes a sealing gasket between two adjacent mounting edges 8, which is tightened and deformed by bolts to achieve a seal, preventing cooling water leakage and allowing cooling water to flow along the cooling channel 9 to cool the first tube seat 4 and the second tube seat 5. It should be noted that the invention includes... Figure 8Only one of the multiple assembly forms of the single quartz lamp heating strip 11 is provided, and the connection sequence of the first heating module 1 and the second heating module 2 in the single quartz lamp heating strip 11 is not unique.
