[0004] In view of this, this application provides an auxiliary tooling and system for temperature chamber testing to solve the problem of poor reproducibility of experimental results when electrical equipment is tested in a temperature chamber.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An auxiliary fixture for temperature chamber testing, used for temperature chamber testing of electrical equipment, includes:

[0007] A windproof structure is used to be installed around the electrical equipment inside the incubator;

[0008] A windbreak assembly, disposed on the windbreak structure, is used to prevent the airflow introduced by the air inlet of the temperature chamber from blowing directly onto the electrical equipment.

[0009] In some embodiments of this application, the windbreak structure includes a first support and a second support arranged opposite to each other, the first support and the second support being respectively arranged on both sides of the periphery of the electrical equipment; the windbreak assembly includes a top windbreak member, one end of the top windbreak member being disposed on the top of the first support, and the other end of the top windbreak member being disposed on the top of the second support.

[0010] In some embodiments of this application, the top-level windbreak is configured as a rigid windbreak;

[0011] Alternatively, at least a portion of the structure of the top-level windbreak is configured as a flexible structure;

[0012] Alternatively, the top-level windbreak is configured as an extendable windbreak.

[0013] In some embodiments of this application, the top-level windbreak includes a first baffle disposed on the first bracket and a second baffle disposed on the second bracket, wherein the first baffle is connected to the second baffle.

[0014] In some embodiments of this application, the first baffle and the second baffle are fixedly connected or movably connected.

[0015] In some embodiments of this application, the first baffle and the second baffle are connected by a hinge, the first baffle and the first bracket are connected by a hinge, and the second baffle and the second bracket are connected by a hinge.

[0016] In some embodiments of this application, the first baffle and the second baffle are connected by an overlap, and the first baffle and the second baffle can slide relative to each other along the mating surface formed by the overlap.

[0017] In some embodiments of this application, the first baffle and the second baffle are connected by a flexible windproof cloth.

[0018] In some embodiments of this application, the top windbreak is disposed on the top of the first bracket in a sliding fit along a first direction;

[0019] And / or, the top windbreak is disposed on the top of the second bracket in a sliding fit along the first direction;

[0020] Wherein, the first direction is the direction in which the first bracket faces the second bracket.

[0021] In some embodiments of this application, the top-level windbreak is configured as a windbreak cloth with a roller shutter mechanism, which is disposed on the first support and / or the second support and is used to adjust the unfolded length of the windbreak cloth.

[0022] In some embodiments of this application, the windbreak assembly further includes a first side windbreak component, which is disposed on the first bracket and connected to the top windbreak component;

[0023] And / or, the windbreak assembly further includes a second side windbreak component, which is disposed on the second bracket and connected to the top windbreak component.

In practical applications, when performing chamber testing on electrical equipment, both the auxiliary fixture and the electrical equipment are placed inside the chamber, with the windbreak structure positioned around the equipment. The windbreak component on the windbreak structure prevents the airflow introduced by the chamber's air inlet from directly blowing onto the electrical equipment. This means that regardless of the electrical equipment's placement within the chamber, it will not be subjected to the direct blowing frequency of the airflow introduced by the air inlet, thus avoiding significant differences in the blowing frequency caused by the equipment's different placement positions within the chamber and improving the reproducibility of experimental results.

[0050] The core of this application is to provide an auxiliary tooling and system for temperature chamber testing, in order to solve the problem of poor reproducibility of experimental results when electrical equipment is tested in a temperature chamber.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] In existing technologies, temperature chamber testing, by simulating different temperature environments, can comprehensively evaluate the performance, reliability, and durability of electrical equipment. However, in existing technologies, when electrical equipment is placed in different positions within the temperature chamber, the varying airflow frequencies at each position lead to poor reproducibility of experimental results and introduce uncontrollable errors into sample testing.

[0053] Specifically, the temperature chamber 1 is typically equipped with a fan or airflow device to achieve uniform temperature distribution and rapid temperature changes. However, due to factors such as the structural design of the temperature chamber 1, the fan layout, and the shape and size of the electrical equipment itself, the airflow distribution inside the temperature chamber 1 is not uniform. When the electrical equipment 3 is placed in different positions within the temperature chamber 1, some positions may experience direct airflow from the air inlet 11, resulting in a higher frequency and intensity of airflow. Conversely, some positions may not experience direct airflow from the air inlet 11, resulting in a lower frequency and intensity of airflow. This difference in airflow frequency leads to variations in the frequency and intensity of airflow experienced by the electrical equipment 3 at different placement positions. Due to these variations in airflow frequency, the electrical equipment 3 may experience different thermal stress conditions during testing. This can cause fluctuations in its performance, reducing the reproducibility of experimental results. Furthermore, this uncontrollable error may mask the true performance of the electrical equipment 3 under specific conditions, thus affecting the accurate assessment of its reliability and durability.

[0054] To address this issue, common methods include increasing the number of temperature sensors inside the incubator to more accurately monitor temperature changes at different locations; adjusting the layout and power of the fans to improve airflow distribution within the incubator; and employing more advanced temperature control systems to achieve more precise and stable temperature control. However, while these methods can alleviate the problem to some extent, they do not fundamentally solve the issues of poor experimental reproducibility and uncontrollable errors caused by varying airflow frequencies.

[0055] Based on this, one embodiment of this application provides an auxiliary tooling 2 for temperature chamber testing, applied to temperature chamber testing of electrical equipment, referring to... Figure 1 and Figure 2 The auxiliary tooling 2 for the temperature chamber test can specifically include a windbreak structure 21 and a windbreak assembly 22, wherein, referring to Figure 1 The incubator 1 has an air inlet 11 and an air outlet 12, combined with Figure 2The windbreak structure 21 is used to be installed on the periphery of the electrical equipment 3 inside the temperature chamber 1. The windbreak structure 21 can be directly designed inside the temperature chamber 1, and can be an integral structure with the temperature chamber or a separate structure. In the case of a separate structure, the windbreak structure 21 can be placed inside the temperature chamber 1 when performing temperature chamber testing. The windbreak component 22 is installed on the windbreak structure 21. The windbreak component 22 is used to block the airflow introduced by the air inlet 11 of the temperature chamber 1 from blowing directly onto the electrical equipment 3. The specific structural form of the windbreak component 22 is not limited, as long as it can play a role in blocking the wind and meet the working conditions of the temperature chamber 1.

[0056] In practical applications, when performing temperature chamber testing on electrical equipment 3, both the temperature chamber testing auxiliary fixture 2 and electrical equipment 3 are placed inside the temperature chamber 1, and the wind baffle 21 is arranged around the electrical equipment 3. The wind baffle component 22 on the wind baffle 21 can block the airflow introduced by the air inlet 11 of the temperature chamber 1 from blowing directly onto the electrical equipment 3. That is, under the action of the wind baffle component 22, no matter where the electrical equipment 3 is placed in the temperature chamber 1, the electrical equipment 3 will not be subjected to the blowing frequency of the airflow introduced by the air inlet 11. This avoids the situation where the blowing frequency of the electrical equipment 3 varies greatly due to different placement positions in the temperature chamber 1, which helps to improve the reproducibility of the experimental results.

[0057] It should be noted that the aforementioned electrical equipment can specifically be power conversion equipment, such as inverters and rectifiers, or other electrical equipment that requires temperature chamber testing.

[0058] In some specific implementation plans, refer to Figure 2As shown, the aforementioned windbreak structure 21 may specifically include a first support 211 and a second support 212 arranged opposite to each other. The first support 211 and the second support 212 are respectively arranged on both sides of the periphery of the electrical equipment 3. The first support 211 and the second support 212 may be designed as a frame structure. The frame structure may specifically include two parallel pillars. The two pillars can be connected by a transverse rigid member to form a frame structure. The bottom of the pillar may be designed as a T-shaped structure to increase the contact area between the bottom of the pillar and the placement surface inside the incubator 1, thereby enhancing the stability of the placement. In addition, by designing the windbreak structure 21 as a structure with the first support 211 and the second support 212 arranged opposite to each other, the windbreak structure 21 occupies less space, which can reserve sufficient placement space for the electrical equipment 3. It also creates conditions for adjusting the spacing between the first support 211 and the second support 212 in the following scheme to meet the needs of electrical equipment of different sizes. The aforementioned windbreak assembly 22 may specifically include a top-level windbreak 221, one end of which is disposed on the top of the first support 211, and the other end of which is disposed on the top of the second support 212. This type of auxiliary tooling for temperature chamber testing is mainly suitable for situations where the air inlet 11 is designed on the top of the temperature chamber 1 or on the side of the temperature chamber 1 and close to the top. In this case, the top-level windbreak 221 can prevent the airflow introduced by the air inlet 11 from directly blowing onto the electrical equipment 3.

[0059] It should be noted that the aforementioned top-level windbreak 221 can be specifically constructed as a rigid windbreak; or at least part of the structure of the top-level windbreak 221 can be constructed as a flexible structure, that is, part or all of the structure of the top-level windbreak 221 can be designed as a flexible structure. Such a design can facilitate the adjustment of the distance between the first support 211 and the second support 212 to meet the placement requirements of electrical equipment 3 of different sizes; or the top-level windbreak 221 can be constructed as an extendable windbreak, for example, the top-level windbreak 221 can be designed as a retractable corrugated windbreak structure, or as a retractable windbreak structure, etc. By designing it as an extendable windbreak, the distance between the first support 211 and the second support 212 can also be adjusted.

[0060] In some specific implementations, the aforementioned top-level windbreak component 221 can be designed as a baffle structure. The baffle structure can be made of, but is not limited to, aluminum alloy. Specifically, the baffle structure may include a first baffle 2211 mounted on the first support 211 and a second baffle 2212 mounted on the second support 212. The first baffle 2211 and the second baffle 2212 are connected, and the connection can be either movable or fixed. By designing the top-level windbreak component 221 with the above-mentioned structure, the windbreak surface is more stable, resulting in better windbreak performance. Furthermore, dividing the top-level windbreak component 221 into two parts makes it easier to manufacture.

[0061] In a further implementation, the first baffle 2211 and the second baffle 2212 are movably connected. Specifically, the first baffle 2211 and the second baffle 2212 can be connected by a hinge. Correspondingly, the first baffle 2211 can also be connected to the first support 211 by a hinge, and the second baffle 2212 can also be connected to the second support 212 by a hinge. By designing the structure as described above, the swivel characteristic of the hinged connection can be used to adjust the distance between the first support 211 and the second support 212. This allows the user to adjust the opening angle and stability of the baffle structure according to actual needs, adapting to different testing conditions or changes in the size of electrical equipment.

[0062] It is understandable that the movable connection between the first baffle 2211 and the second baffle 2212 can also be designed as an overlapping connection, allowing the first baffle 2211 and the second baffle 2212 to slide relative to each other along the mating surface formed by the overlap. In this case, the connection between the first baffle 2211 and the first support 211 can be either a fixed connection or a hinged connection, and the connection between the second baffle 2212 and the second support 212 can also be either a fixed connection or a hinged connection. By designing the structure as described above, the spacing between the first support 211 and the second support 212 can also be adjusted.

[0063] In addition, the movable connection between the first baffle 2211 and the second baffle 2212 can also be designed such that the first baffle 2211 and the second baffle 2212 are connected by a flexible windproof cloth. The deformable characteristics of the flexible windproof cloth allow the first baffle 2211 and the second baffle 2212 to move closer together or further apart, thereby achieving adjustment of the distance between the first support 211 and the second support 212.

[0064] Furthermore, the movable connection between the first baffle 2211 and the second baffle 2212 can also be designed such that the top windbreak 221 is slidably fitted onto the top of the first support 211 in a first direction; and / or, the top windbreak 221 is slidably fitted onto the top of the second support 212 in a first direction; wherein, the first direction is the direction from the first support 211 toward the second support 212. The distance between the first support 211 and the second support 212 can also be adjusted by sliding the top windbreak 221 along the first direction.

[0065] In some other specific embodiments, the aforementioned top-level windbreak component 221 can also be configured as a windbreak cloth with a roller shutter mechanism. This roller shutter mechanism allows adjustment of the unfolded length of the windbreak cloth, ensuring that the distance between the first support 211 and the second support 212 can be adjusted while maintaining a good wind-blocking effect under taut conditions. It should be noted that when there is only one roller shutter mechanism, it can be installed on either the first support 211 or the second support 212. When there are two roller shutter mechanisms, one can be installed on the first support 211 and the other on the second support 212, allowing the windbreak cloth to be extended and retracted simultaneously from both sides.

[0066] In some other specific implementation schemes, refer to Figure 2As shown, the aforementioned windbreak assembly 22 may further include a first side windbreak member 222, which is disposed on the first bracket 211. If the first side windbreak member 222 is a rigid member (such as a rigid baffle), it can serve as a lateral rigid connector of the first bracket 211. If the first side windbreak member 222 is a flexible member (such as a flexible windbreak cloth), it serves as an additional component of the frame structure of the first bracket 211. Furthermore, the first side windbreak member 222 is arranged on the first bracket 211 to shield the frame containing the first bracket 211 and connect with the top windbreak member 221. This first side windbreak member 222 is mainly used to prevent the outer side of the electrical equipment 3 from being directly blown by the airflow from the air inlet 11. Similarly, the windbreak assembly 22... It may also include a second side wind deflector 223, which is disposed on the second bracket 212. The second side wind deflector 223 is disposed on the first bracket 212. If the second side wind deflector 223 is a rigid component (such as a rigid baffle), it can serve as a transverse rigid connector of the second bracket 212. If the second side wind deflector 223 is a flexible component (such as a flexible wind deflector cloth), it serves as an additional component of the frame structure of the first bracket 212 itself. In addition, the arrangement of the second side wind deflector 223 on the second bracket 213 is to shield the frame where the second bracket 212 is located and to connect with the top wind deflector 221. The second side wind deflector 223 is mainly used to block the side of the outer periphery of the electrical equipment 3 from the direct blowing of the airflow from the air inlet 11.

[0067] In some other specific implementation schemes, refer to Figure 3 As shown, at least two sets of wheels 23 can also be provided at the bottom of the aforementioned windshield structure 21. By designing the wheels 23, the position adjustment of the windshield structure 21 within the temperature chamber 1 can be made more convenient. In addition, at least one set of wheels 23 can be equipped with a braking mechanism, which makes it easier to fix the windshield structure 21 in position after it has been adjusted.

[0068] It is understandable that when the windbreak structure 21 is designed as an integral structure with the temperature chamber 1, the windbreak structure 21 can be designed to be fixedly connected to the inner surface of the temperature chamber 1, or it can be designed to be slidably connected. For example, the inner surface of the temperature chamber is designed with corresponding slide rails, and the windbreak structure 21 is slidably set on the slide rails.

[0069] In some other specific implementations, in order to better accommodate the height of the electrical equipment 3, the windbreak structure 21 can also be constructed as a liftable support structure, for example, the support column of the windbreak structure 21 can be designed as a telescopic support column.

[0070] On the other hand, this application also provides a temperature chamber testing system, including a temperature chamber 1 and a temperature chamber testing auxiliary fixture 2 as described in any of the foregoing solutions. Since the aforementioned temperature chamber testing auxiliary fixture 2 has the aforementioned technical effects, the temperature chamber testing system with the temperature chamber testing auxiliary fixture 2 should also have the corresponding technical effects, which will not be elaborated here.

[0071] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
