[0003] However, the heat transfer efficiency of the heat transfer rods in the commonly used high and low temperature alternating damp heat test chambers is not high.

[0004] For example, the heat transfer rod of the high and low temperature alternating damp heat test chamber disclosed in Chinese patent CN105333760A has a pair of protective rods on both sides of the heat transfer rod body, and a connector for connecting to the heat source is set at each end of the heat transfer rod body. An adjustment knob is set on each connector, and the surface of each adjustment knob is covered with heat insulation rubber, which greatly improves the heat transfer efficiency of the heat transfer rod of the high and low temperature alternating damp heat test chamber.

[0005] However, the heat transfer rods used in the existing technology have relatively fixed dimensions during use, which makes it inconvenient to adjust the length of the heat transfer rod according to the needs of the application scenario or the size and model of the test chamber. In addition, the surface of the heat transfer rod is usually smooth, resulting in relatively low thermal conductivity and thermal conductivity area.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: The heat transfer rods used in existing technologies have relatively fixed dimensions during use, making it inconvenient to adjust their length according to the requirements of the application scenario or the size and model of the test chamber. Furthermore, the surface of the heat transfer rods is usually smooth, resulting in relatively low thermal conductivity and area. Please refer to... Figures 1-5 The embodiment provides a heat transfer rod for a high and low temperature alternating damp heat test chamber, which can effectively and flexibly adjust the length of the heat transfer rod, while effectively improving the heat conduction area and heat conduction efficiency of the rod. The heat transfer rod for the high and low temperature alternating damp heat test chamber includes a main heat transfer rod 1. Auxiliary devices are installed on the outer surface and left and right sides of the main heat transfer rod 1. Fixing devices are installed at the left and right ends of the auxiliary devices. Adjustment and protection devices are provided on the front and back of the auxiliary devices.

[0021] The auxiliary device includes a connecting rod 2, a secondary rod 3 connected to the outer surface of the connecting rod 2, a titanium metal protective layer 4 installed on the outer surface of the main heat transfer rod 1 and the secondary rod 3, a nano-ceramic protective layer 5 installed on the outer surface of the titanium metal protective layer 4, fins 6 installed on the outer surface of the nano-ceramic protective layer 5, and a connector 7 installed at the end of the secondary rod 3 away from the main heat transfer rod 1.

[0022] Connecting rod 2 is fixedly installed at both ends of the main heat transfer rod 1. The auxiliary rod 3 has a threaded groove at one end near the main heat transfer rod 1. The outer surface of connecting rod 2 is threadedly connected to the inside of the threaded groove of auxiliary rod 3. Fins 6 are spirally fixedly installed on the outer surface of nano-ceramic protective layer 5. A threaded hole is opened in the middle of the top surface of connector 7.

[0023] With the auxiliary device, the threaded connection between the connecting rod 2 and the auxiliary rod 3 facilitates the adjustment of the overall length of the main heat transfer rod 1 and the auxiliary rod 3. The titanium metal protective layer 4 and the nano-ceramic protective layer 5 protect the rod body from corrosion and damage caused by moisture and high temperature. At the same time, the fins 6 effectively improve the heat conduction area and heat conduction efficiency.

[0024] During the assembly of the rod body, the main heat transfer rod 1 and the secondary rod 3 are connected by threads through the connecting rod 2, thereby adjusting the overall length of the main heat transfer rod 1 and the secondary rod 3. Then, it is easy to install and fix it using the connector 7. During use, the installation of the titanium metal protective layer 4 and the nano-ceramic protective layer 5 ensures the heat conduction efficiency of the rod body and effectively prevents the rod body from being corroded by high temperature and moisture. At the same time, the spiral installation of the fins 6 effectively improves the heat conduction area and heat conduction efficiency. The spiral staggered arrangement of the fins 6 forms a spiral channel, which extends the airflow path, enhances radial mixing, and improves the heat exchange efficiency by 40%~60% compared with straight fins, and can evenly distribute heat.

[0025] Example 2: Based on Implementation 1, the existing technology still has the problem that the protective angle and position of the pole are not easily adjustable. Please refer to... Figures 1-5 The embodiment provides a heat transfer rod for a high and low temperature alternating damp heat test chamber, which can effectively solve the problem of adjusting the protection angle and protection position of the rod. The fixing device of the heat transfer rod for the high and low temperature alternating damp heat test chamber includes a mounting base 8, a fixing bolt 9 installed in the middle of the top surface of the mounting base 8, a fixing rod 10 installed in the middle of the bottom surface of the mounting base 8, and a fixing seat 11 installed at the bottom end of the fixing rod 10. A fixing groove is opened in the middle of the mounting base 8, and the inside of the fixing groove is connected to the outer surface of the connector 7. The outer surface of the fixing bolt 9 is threadedly connected to the inner wall of the threaded hole opened in the middle of the top surface of the connector 7.

[0026] The adjustable protective device includes an adjusting seat 12, an adjusting block 13 installed inside the adjusting seat 12, and a protective rod 14 installed at the end of the adjusting block 13 away from the adjusting seat 12. A limit hole is opened on the side of the adjusting seat 12, and a limit bolt 15 is connected inside the limit hole. The adjusting block 13 is hinged to the middle of the adjusting seat 12. The adjusting seat 12 is fixedly installed on the middle of the front and back of the mounting base 8. The outer surface of the limit bolt 15 is connected to the inside of the limit hole opened in the middle of the adjusting block 13.

[0027] By setting up a fixing device and an adjustable protective device, the rod body is installed and fixed using the mounting base 8 and the fixing base 11. The position of the protective rod 14 is easily adjusted by the hinge between the adjusting block 13 and the adjusting base 12, and the limiting bolt 15 is used for limiting and fixing.

[0028] When installing and fixing the rod, the connector 7 and the mounting base 8 are connected by a snap-fit ​​mechanism inside the mounting groove, and the fixing bolt 9 is used to limit and fix the connector 7 and the mounting base 8, thus facilitating the installation and fixing of the rod. At the same time, the fixing rod 10 and the fixing base 11 are used for installation and fixing to ensure the stability of use. The hinge between the adjusting block 13 and the adjusting base 12 allows for flexible adjustment of the installation position and angle of the protective rod 14. Then, the limiting bolt 15 is used to limit the adjusting base 12 and the adjusting block 13 to maintain the stability after adjustment. After adjusting the protective rod 14, the protective effect of the rod is effectively improved and the heat distribution is effectively optimized.
