Technical Field

[0001] This utility model relates to an infrared heating cage, belonging to the technical field of aviation environment simulation equipment. Background Technology

[0002] In space simulation equipment, infrared heating cages are primarily used to ensure the stability of the temperature field within the space and to guarantee that the temperature reaches predetermined requirements. Traditional space environment simulation equipment often uses custom-designed infrared heating cages, meaning the cage is a customized structure designed for different products, resulting in high costs. However, with increasing experimental requirements, infrared heating cages are now required to be manufactured in various sizes and shapes, leading to longer lead times and higher costs for custom-designed cages. To meet the needs of different products, a more versatile heating cage needs to be designed to adapt to the specific requirements of various products. Utility Model Content

[0020] The present invention will be further described below with reference to the embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading this description, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] Example 1, please refer to Figures 1 to 6As shown, the detachable and modular infrared heating cage of this embodiment includes a movable base 1 and several heating element assemblies 2. Each heating element assembly 2 includes a frame base and heating strips 201 fixed to the surface of the frame base. The heating strips 201 on each heating element assembly 2 can be controlled independently. That is, the heating temperature of the heating strips 201 on one heating element assembly 2 can be uniformly controlled, or the heating strips 201 on one heating element assembly 2 can be divided into multiple control groups, each with its own heating temperature controlled. This allows different heating element assemblies 2 to obtain different heating temperatures as needed. The side of the heating strip facing inwards from the cage is coated with aviation black paint to improve its radiation capability.

[0022] Specifically, in the heating element assembly 2, the frame base is welded and fixed into a rectangular frame using stainless steel square tubing. The rectangular frame sequentially includes a first side 202, a second side 203, a third side 204, and a fourth side 205. Thin-plate heat-insulating gaskets 206 are bolted to the first side 202 and the third side 204 of the rectangular frame. Several heating strips 201 are then bolted between the heat-insulating gaskets 206 on the first side 202 and the third side 204, meaning that the two ends of each heating strip 201 are respectively fixed to the heat-insulating gaskets 206 on the first side 202 and the third side 204. In this embodiment, the heating strips 201 are arranged parallel to the second side 203 and the fourth side 205. Terminal blocks 207 are fixed on the first side 202 or the third side 204 of the rectangular frame. All the connecting wires of the heating strips 201 are connected to the terminal blocks 207 to achieve electrical connection. In this way, the external power supply circuit can supply power to the heating strips 201 and control them through the terminal blocks 207.

[0023] On the stainless steel square tubes forming the first side 202 and the third side 204 of the rectangular frame, connection holes are provided at both ends. These connection holes are used to connect with corner brackets to achieve assembly with other heating element assemblies 2. During assembly, the second side 203 of the rectangular frame of the preceding heating element assembly 2 and the fourth side 205 of the rectangular frame of the following heating element assembly 2 are arranged side by side. The corner brackets used to connect multiple heating element assemblies 2 can have various shapes; please refer to... Figure 4 , Figure 5As shown, this embodiment uses a first corner bracket 3a and a second corner bracket 3b. Both the first corner bracket 3a and the second corner bracket 3b are sheets, each with a first fixing hole 301 and a second fixing hole 302. The first fixing hole 301 is used to fix the first heating element assembly 2, and the second fixing hole 302 is used to fix the second heating element assembly 2. In this embodiment, the first corner bracket 3a has three sets of first fixing holes 301 and second fixing holes 302. Each set of first fixing holes 301 consists of two holes, one of which is shared by multiple sets of first fixing holes 301. Each set of second fixing holes 302 also consists of two holes, one of which is shared by multiple sets of second fixing holes 302. The angle between the line connecting the first fixing holes 301 and the line connecting the second fixing holes 302 forms angles of 180°, 165°, 150°, 135°, and 120°. By selecting different first fixing holes 301 and second fixing holes 302, different angles can be achieved between the two heating element assemblies 2. The second corner code 3b is provided with a set of first fixing holes 301 and two sets of second fixing holes 302. The angle between the line connecting the first fixing holes 301 and the line connecting the second fixing holes 302 is 150° and 90°, respectively, and the angle between the lines connecting the two sets of second fixing holes 302 is 120°.

[0024] In this embodiment, the infrared heating cage is composed of nine heating element assemblies 2 connected together. They are sequentially connected using the following methods: first fixing holes 301 and 302 at a 180° angle for the first angle bracket 3a; first fixing holes 301 and 302 at a 150° angle for the first angle bracket 3a; first fixing holes 301 and 302 at a 150° angle for the second angle bracket 3b; first fixing holes 301 and 302 at a 150° angle for the two first angle brackets 3a; first fixing holes 301 and 302 at a 150° angle for the second angle bracket 3b; first fixing holes 301 and 302 at a 150° angle for the first angle bracket 3a; and first fixing holes 301 and 302 at a 180° angle for the first angle bracket 3a. Figure 1 As shown. The heating element assemblies 2 at both ends are connected to the movable base 1. Please refer to... Figure 6 As shown, the bottom of the movable base 1 is equipped with a support wheel 101 and a guide wheel 102. The axle of the support wheel 101 is horizontally set, and the axle of the guide wheel 102 is vertically set. In this way, the entire detachable and assembled infrared heating cage can be moved on a set of tracks 4 by the support wheel 101, and the guide wheels 102 of the two movable bases 1 are locked between the two tracks 4 for guidance.

[0025] Example 2, please refer to Figure 7As shown, the detachable and modular infrared heating cage of this embodiment differs from Embodiment 1 in that the connection method of each heating element assembly 2 is different. Specifically, it is still composed of nine heating element assemblies 2 connected together. The third heating element assembly 2 and the fourth heating element assembly 2, and the sixth heating element assembly 2 and the seventh heating element assembly 2 are fixedly connected by the first fixing hole 301 and the second fixing hole 302 at a 90° angle of the second angle bracket 3b. The other adjacent heating element assemblies 2 are fixedly connected by the first fixing hole 301 and the second fixing hole 302 at a 180° angle of the first angle bracket 3a. As can be seen from the changes in this embodiment compared to Embodiment 1, by changing the connection method of each component through the structure of this utility model, the shape of the detachable and modular infrared heating cage can be flexibly changed, thereby improving its applicability. It should also be noted that the size of the infrared heating cage can be further changed by selectively removing some heating element assemblies 2 and the corresponding angle brackets.
