Description

[Technical Field]

[0001] This utility model relates to the field of fan testing, specifically to a temperature-controlled room for fan temperature testing. [Background Technology]

[0002] In some subtropical countries, the climate is characterized by high temperature and humidity year-round, with significant seasonal variations. Summer average temperatures can reach 35-40℃, posing numerous challenges to fan performance. For example, motor heat dissipation, the adaptability of fan components to thermal expansion and contraction, and lifespan all face severe tests. Therefore, fans used in these regions often need to meet higher requirements. During research and development and production, even manufacturers located in non-subtropical countries can build testing environments to test fan performance under specific temperature conditions. This ensures that the fans can operate normally in real-world working environments with drastic temperature changes, thus adapting to different regional climatic conditions.

[0003] However, traditional testing methods typically rely on the natural environment or simple heating equipment. These methods have several problems, such as excessively long testing times and uncontrollable environmental conditions, leading to unstable testing conditions and inaccurate results. Therefore, developing a temperature-controlled chamber suitable for testing fan temperatures is of great significance for improving the efficiency of fan testing and ensuring the accuracy of experimental results.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0007] As described above, a temperature-controlled room for fan temperature testing has two sets of air outlets. One set of air outlets is directly connected to the output end, and the other set of air outlets is connected to the output end by a conveying pipe. The conveying pipe extends from the output end into the interior of the temperature-controlled room and is connected to the air outlet.

[0008] As described above, in a temperature-controlled room for fan temperature testing, the heating component further includes an auxiliary heating assembly for radiating heat energy into the interior of the temperature-controlled room. The auxiliary heating assembly consists of several heating elements, which are evenly laid out on the inner side wall of the temperature-controlled room.

[0009] As described above, a temperature-controlled chamber for fan temperature testing includes a connecting part for fixing a temperature sensor. The connecting part includes at least one support member, a base, and a hinge. The base is fixed to the side wall of the temperature-controlled chamber. One end of the support member is connected to the base, and the other end is used to connect to the temperature sensor. The support member and the base are connected via the hinge. The hinge includes a first hinge, a second hinge, a rotating shaft, and a positioning member. The first hinge is located at one end of the support member, and the second hinge is located on the base. The rotating shaft passes through the first and second hinges to achieve a rotatable connection between the support member and the base. The positioning member restricts the movement of the support member at a set position.

[0010] As described above, in a temperature-controlled room for fan temperature testing, the support includes a first arm segment and a second arm segment nested and connected to one end of the first arm segment. The first arm segment and the second arm segment are slidable relative to each other. The support also includes a locking device, which is used to stretch or retract the first arm segment and the second arm segment to a target position and keep them fixed in the current position. The locking device is a snap-fit ​​structure.

[0011] As described above, in a temperature-controlled room for fan temperature testing, the support member has a hollow structure. The inner wall of the first support arm section is provided with a guide rail, and the outer wall of the second support arm section is provided with a corresponding slider. The slider cooperates with the guide rail to achieve relative sliding between the first and second support arm sections.

[0012] As described above, a temperature-controlled room for fan temperature testing is provided inside the temperature-controlled room. The fan assembly is used to agitate the airflow inside the temperature-controlled room to enhance airflow.

[0015] As described above, in a temperature-controlled room for fan temperature testing, the outer layer of the delivery pipe is provided with a heat-insulating sleeve to prevent heat exchange between the inside of the delivery pipe and the external environment.

[0016] Compared with existing technologies, the temperature-controlled room for fan temperature testing of this utility model has the following advantages:

[0017] 1. This application, by precisely controlling the temperature conditions of the temperature-controlled chamber, can create a stable testing environment in a short time, significantly improving fan testing efficiency. Simultaneously, precise temperature control and real-time monitoring ensure the accuracy of test results, providing reliable data support for fan research and development and production.

[0018] 2. This application uses an auxiliary heating component to radiate heat into the temperature-controlled room, which can heat the airflow in a specific area, so that the air temperature inside the temperature-controlled room remains at the set temperature and tends to be uniform.

[0019] 3.

Detailed Implementation Methods

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-7 As shown, this utility model includes a temperature-controlled chamber for fan temperature testing, comprising a controller 1, a temperature-controlled chamber body 2, a heating component 3, and a door 21 that is opened and closed on the side wall of the temperature-controlled chamber body 2 to form an open or closed space with the temperature-controlled chamber body 2. It also includes multiple temperature sensors 4 located inside the temperature-controlled chamber body 2 and electrically connected to the controller 1 for monitoring temperature changes in the temperature-controlled chamber. The temperature-controlled chamber body 2 has multiple air outlets 22 inside. The heating component 3 includes a main heating assembly 31 located at the top of the temperature-controlled chamber body 2 for drawing in air and heating it to a target temperature. The main heating assembly 31 is connected to multiple output terminals, which are connected to the air outlets 22. The controller 1 is electrically connected to the heating component 3 for controlling the operation of the heating component 3.

[0034] Controller 1 is electrically connected to heating element 3 to precisely control its operating status. Temperature sensor 4 is electrically connected to controller 1 to monitor temperature changes in the temperature-controlled room in real time and feed the temperature data back to controller 1. Controller 1 adjusts the operating status of heating element 3 based on the feedback temperature data to ensure the temperature in the temperature-controlled room remains within the set target temperature range. The main heating assembly 31 includes a fan and a heating element. After the fan draws in air, the air passes through the heating element, converting electrical energy into heat energy, thereby heating the air to the set temperature. The heated air is then sent into the temperature-controlled room through the fan's output, thus raising the temperature inside the room. The main heating assembly 31 is located at the top of the temperature-controlled room body 2. The fan's output can be directly connected to the air outlet 22, or it can be connected to the air outlet 22 through a delivery pipe 23, enabling the heated air to be evenly distributed within the temperature-controlled room. It should be noted that the heating element can be an electric heating wire or an electric heating film, which is existing technology.

[0035] This application can precisely control the operating state of the main heating component 31, thereby ensuring that the fan can perform performance testing under the set temperature conditions. At the same time, the airflow control valve 7 provided on the side wall can be used to balance the air pressure inside the temperature control chamber 2, further optimizing the airflow inside the temperature control chamber 2 and avoiding the influence of air pressure changes on the test results.

[0036] The fan or component to be tested is placed inside the temperature-controlled chamber 2. Under high-temperature conditions, the fan's operating status and performance are observed, including indicators such as speed changes, noise levels, and heat dissipation. During the test, it is necessary to ensure the temperature of the test environment is stable to avoid the influence of temperature fluctuations on the test results. After the test, a comprehensive performance check of the fan is required, including speed, noise, and heat dissipation. If performance degradation or abnormalities are found, it will help technicians further analyze the causes and take corresponding improvement measures. It should be noted that the temperature-controlled chamber is also equipped with a cooling component (not shown in the figure) to allow the temperature control range of the chamber to be between -100 degrees Celsius and 200 degrees Celsius. This temperature control range not only meets the testing requirements of high-temperature environments in subtropical regions but is also suitable for experiments and testing scenarios under various extreme temperature conditions. Therefore, the temperature-controlled chamber of this invention is not limited to the testing conditions required in subtropical regions but can be widely applied to various occasions requiring precise temperature control.

[0037] This application enables the creation of a stable testing environment in a short time by precisely controlling the temperature conditions of the temperature-controlled chamber, significantly improving fan testing efficiency. Simultaneously, precise temperature control and real-time monitoring ensure the accuracy of test results, providing reliable data support for fan research and development and production.

[0038] like Figure 1-7 As shown, as a further technical solution of this application, the air outlet 22 is provided with two sets. One set of air outlets 22 is directly connected to the output end, and the other set of air outlets 22 is connected to the output end by a conveying pipe 23. The conveying pipe 23 extends from the output end into the interior of the temperature-controlled room 2 and is connected to the air outlet 22. The heating component 3 also includes an auxiliary heating component 32 for radiating heat energy into the interior of the temperature-controlled room 2. The auxiliary heating component 32 is composed of several heating elements, and the heating elements are evenly laid flat in the inner wall of the temperature-controlled room 2.

[0039] According to Bernoulli's principle, the fan under test generates a low-pressure area on the intake side and a high-pressure area on the exhaust side during operation. This pressure difference is the driving force for airflow. The fan's rotation increases airflow, causing slight fluctuations in local temperature. If the fan speed changes, it will cause more significant temperature changes. Therefore, the auxiliary heating component 32 inside the temperature-controlled chamber 2 has its heating temperature controlled by the controller 1. Since multiple sets of heating elements are laid flat inside the temperature-controlled chamber 2 and simultaneously radiate heat energy into the chamber 2, they heat the air in the corresponding area. The controller 1 adjusts the heating element 32 based on the data collected by the temperature sensor 4, thereby regulating the amount of heat radiated into the temperature-controlled chamber 2 by the auxiliary heating component 32. Furthermore, several heating elements are electrically connected in parallel with the controller 1 and can be controlled individually or in combination by the controller 1. This technical solution, by setting the auxiliary heating component 32, can heat the airflow in a specific area, maintaining the set temperature and making it more uniform inside the temperature-controlled chamber 2.

[0040] like Figure 1-7 As shown, as a further technical solution of this application, in order to ensure that the temperature sensor 4 can be stably and flexibly installed in the temperature-controlled room 2 and that its position and angle can be adjusted as needed, the temperature-controlled room 2 is provided with a connecting part 41 for fixing the temperature sensor 4. The connecting part 41 includes at least one support member 42, a base 43, and a hinge part 44. The base 43 is fixed to the side wall of the temperature-controlled room 2. One end of the support member 42 is connected to the base 43, and the other end is used to connect the temperature sensor 4. The support member 42 and the base 43 are connected by a hinge 44, which includes a first hinge 441a, a second hinge 441b, and a positioning member 443. The first hinge 441a is located at one end of the support member 42, and the second hinge 441b is located on the base 43. A rotating shaft 442 passes through the first hinge 441a and the second hinge 441b to achieve a rotatable connection between the support member 42 and the base 43. The positioning member 443 is used to limit the movement of the support member 42 in a set position. The temperature sensor 4 is connected to the inside of the temperature-controlled room 2 through a connecting part 41 and rotates relative to the base 43 through the hinge 44, thereby adjusting the angle of the temperature sensor 4. Specifically, as shown... Figure 5 , Figure 6As shown, one end of the positioning member 443 is fitted onto the corresponding position of the second hinge 441b, and the two rotate relative to each other. The other end is provided with a sliding groove and several slots. When the position of the first hinge 441a relative to the second hinge 441b changes, it can move in the sliding groove and be limited to the current position by the slots, so as to realize the rotational movement and positioning between the support member 42 and the base 43. Correspondingly, both the first hinge 441a and the second hinge 441b are provided with positioning posts that cooperate with the positioning member 443 to prevent the positioning member 443 from disengaging. The structure is simple and the operation is convenient. In this application, the temperature sensor 4 can be adjusted and fixed by the connecting part 41. Without interfering with the operation of the fan under test, temperature monitoring can be achieved at different positions. Compared with the traditional temperature sensor 4 externally connected to the wall, it avoids interference with the airflow of the fan due to improper installation position of the temperature sensor 4. It not only ensures the flexibility of the installation of the temperature sensor 4, but also ensures that the temperature sensor 4 is not displaced by airflow or other external forces during the test, thereby improving the accuracy and reliability of the test results.

[0041] like Figure 1-7 As a further technical solution of this application, the support member 42 includes a first arm segment 421 and a second arm segment 422 nested and connected to one end of the first arm segment 421. The first arm segment 421 and the second arm segment 422 are slidable relative to each other. The support member 42 also includes a locking device 423, which is used to stretch or retract the first arm segment 421 and the second arm segment 422 to a target position and keep them fixed in the current position. The locking device 423 is a snap-fit ​​structure. The support member 42 has a hollow structure. A guide rail is provided on the inner wall of the first arm segment 421, and a slider is correspondingly provided on the outer wall of the second arm segment 422. The slider cooperates with the guide rail to realize the relative sliding of the first arm segment 421 and the second arm segment 422.

[0042] Specifically, the support member 42 includes a first arm segment 421 and a second arm segment 422. One end of the support member 42 is rotatably engaged with the base 43 to achieve angle adjustment. The other end is slidably engaged with the first arm segment 421 and the second arm segment 422, and is connected to the temperature sensor 4 at the end so that the temperature sensor 4 can extend and retract in the ray direction of the currently fixed angle. The snap-fit ​​structure includes several holes located on the first arm segment 421, distributed along the length of the first arm segment 421. It also includes a retractable protrusion located on the second arm segment 422, the size of which matches the holes. When the support member 42 is locked, pressing the protrusion to a position that does not obstruct the movement of the second arm segment 422 allows for forward or backward extension of the second arm segment 422, thereby adjusting the amount of extension between the first and second arm segments 421. During this extension / retraction, the protrusion is constantly compressed. When the next hole is reached, the protrusion automatically springs back to stop the movement between the first and second arm segments 421, thus adjusting the support member 42 to the desired length. When the monitoring position of the temperature sensor 4 needs adjustment, the user stretches or retracts the support member 42 and uses the locking device 423 to fix it in the desired position to accommodate the extension / retraction of the support member 42. The structure is simple and easy to operate. It should be noted that the sliding engagement method between the slider and the guide rail is existing technology and is a technical means that can be understood by those skilled in the art.

[0043] Meanwhile, the hollow structure inside the support member 42 allows wires to pass through for connecting the temperature sensor 4. In addition, the end of the second arm segment 422 away from the first arm segment 421 is provided with a fixing part for fixing the temperature sensor 4, which is reliable and easy to use.

[0044] like Figure 1-7 As shown, as a further technical solution of this application, at least one fan assembly 5 is provided inside the temperature control chamber 2. The fan assembly 5 is used to disturb the airflow inside the temperature control chamber 2 to enhance airflow. When the object under test is a stationary fan or component, the air velocity is higher near the air outlet 22, which easily creates an air pressure difference. This technical solution utilizes the air pressure difference to drive the airflow inside the temperature control chamber, providing driving force for the fan assembly 5, causing the fan assembly 5 to rotate and further disturb the airflow inside the temperature control chamber 2, which helps to evenly distribute the hot air inside the temperature control chamber.

[0045] like Figure 2 , Figure 3As shown, as a further technical solution of this application, the temperature control chamber 2 also includes a support assembly 6. The support assembly 6 includes at least one set of symmetrically arranged upright supports 61, with horizontal support rods 62 erected between the upright supports 61. In this application, two sets of symmetrically arranged upright supports 61 are connected to the horizontal supports, and the two are fixedly connected to the temperature control chamber by fasteners (existing technology), which helps to enhance the structural stability of the temperature control chamber. This structure not only supports the temperature control chamber but also provides a location for installing the device under test, improving the space utilization of the temperature control chamber. Furthermore, the support assembly 6 has a hollow internal structure, with the power supply line routed along the inside of the support assembly 6, avoiding exposed wires, reducing interference with airflow, and improving the neatness and safety of the wiring.

[0046] like Figure 3 As shown, the outer layer of the conveying pipe 23 is further provided with a heat insulation sleeve 231 to isolate the interior of the conveying pipe 23 from heat exchange with the external environment. In practical applications, the heat insulation sleeve 231 can be made of heat insulation materials such as fiberglass or polyurethane foam, which have good heat insulation performance and durability. The heat insulation sleeve 231 can be installed on the outer layer of the conveying pipe 23 by wrapping, winding, or fixing, ensuring a tight fit and preventing loosening due to airflow vibration. This technical solution can effectively prevent the hot air inside the conveying pipe 23 from cooling due to external influences, thus ensuring the temperature uniformity and stability within the temperature-controlled room.

[0047] like Figure 2 As shown, specifically, this application also includes an observation window 24 on the door 21 for observing the interior of the temperature-controlled chamber 2 from the outside. The temperature-controlled chamber 2 is also equipped with a high-temperature resistant lamp 25 for illumination. The observation window 24 is made of transparent material and can withstand the high-temperature environment inside the temperature-controlled chamber 2, ensuring that operators can safely and clearly observe the internal testing process. The design of the observation window 24 not only improves the transparency of the test but also enhances the convenience of operation, allowing technicians to monitor the internal testing status in real time without entering the temperature-controlled chamber 2. Furthermore, the high-temperature resistant lamp 25 installed inside the temperature-controlled chamber 2 ensures sufficient illumination inside the chamber 2 during the test, facilitating the observation and recording of test data.

[0048] To improve the operational flexibility of the temperature-controlled room, a video monitor 9 (not shown in the diagram) is also installed in the temperature-controlled room 2. This video monitor 9 is electrically connected to the controller 1, enabling remote monitoring of the operation within the temperature-controlled room 2 via the controller 1. Furthermore, the video monitor 9 has data storage capabilities, recording and storing monitoring data so that staff can review historical monitoring information at any time, analyze anomalies, and make early warnings and predictions.

[0049] like Figure 1 , Figure 2 As shown, further, the temperature control chamber further includes a heat insulation bottom plate 71 for preventing heat from dissipating from the ground. The heat insulation bottom plate 71 is hermetically connected to the bottom of the temperature control chamber body 2, effectively preventing the hot air in the temperature control chamber from exchanging heat with the outside world, avoiding temperature drop caused by heat dissipation, and ensuring the accuracy of test results.

[0050] As Figure 1-7 As shown, the present application further includes a control system for a temperature control chamber for fan environment testing, including the above-mentioned temperature control chamber for fan environment testing. The control system includes a touch screen, a temperature control module, a pressure control module, a humidity control module, an abnormal warning module and a processor. The touch screen includes a display module and an input module. The display module is used to present images and information, and the input module is used to receive the touch operation of the user; the temperature control module includes a heating component 3 and a temperature sensor 4. The processor is electrically connected to the heating component 3 and the temperature sensor 4, and is used to control the heating component 3 and identify the temperature detected by the temperature sensor 4 to adjust the temperature in the temperature control chamber body 2, so as to make the temperature in the chamber meet the set temperature range; the pressure control module is electrically connected to the processor and is used to control and adjust the air pressure in the temperature control chamber body 2; the pressure control module is electrically connected to the processor and is used to control and adjust the air pressure in the temperature control chamber body 2; the abnormal warning module is used to issue a warning when an abnormality occurs in the internal environment of the temperature control chamber body 2.

[0051] The temperature sensors 4 are distributed at different positions in the temperature control chamber body 2 and are used to monitor the temperature conditions in the temperature control chamber body 2 in real time. When the ambient temperature in the temperature control chamber body 2 exceeds the set temperature value, cooling treatment is performed, and when the ambient temperature in the temperature control chamber body 2 is lower than the set temperature value, heating treatment is performed. The temperature control module, the pressure control module and the humidity control module can all operate independently, and respectively precisely control the temperature, air pressure and humidity in the temperature control chamber. In addition, these modules can also work together through the processor to achieve multi-parameter linkage control to meet the diverse needs of different test pieces for the test environment. Through this modular design and flexible control method of the technical solution, the control function of the temperature control chamber has stronger adaptability and can meet the needs of a variety of complex test scenarios.

[0052] In order to improve the operation flexibility of the temperature control chamber, a video monitor 9 (not shown in the figure) electrically connected to the controller 1 is also provided in the temperature control chamber body 2. The video monitor 9 is electrically connected to the processor and can monitor the operation status in the temperature control chamber body 2 through the processor. The video monitor 9 can also have the function of storing data, so that the staff can retrieve and view the working conditions of the historical monitored temperature control chamber, thereby analyzing abnormal situations and making early warning predictions.

[0053] Specifically, the air pressure control module includes an air pressure sensor 831 and an airflow control valve 7. The air pressure sensor 831 is used to monitor the air pressure inside the temperature control chamber 2, and the airflow control valve 7 is used to add or remove air into the temperature control chamber to balance the air pressure inside the temperature control chamber. The air pressure control module controls the air pressure inside the temperature control chamber 2 through the processor to make it meet the test conditions.

[0054] In addition, the humidity control module includes a humidity sensor 841 and a spray assembly (not shown in the figure). The humidity sensor 841 monitors the humidity inside the temperature-controlled chamber 2, and the spray assembly increases the air humidity. The humidity control module controls the humidity inside the temperature-controlled chamber 2 through a processor to ensure it meets the testing conditions. The spray assembly is located below the fan, near the air outlet 22. It utilizes the fan to output hot air, distributing the atomized particles evenly throughout the temperature-controlled chamber with the airflow. Simultaneously, the abnormal warning module is equipped with a buzzer or indicator light to help staff promptly detect and handle abnormal situations, ensuring the safety of the testing process.

[0055] The control process for the temperature-controlled room used for fan environment testing is as follows:

[0056] S1. Through the input module on the touch screen, the operator sets environmental parameters such as target temperature, air pressure, and humidity, as well as the test mode and running time.

[0057] S2. The temperature sensor 4, air pressure sensor 831, and humidity sensor 841 are used to monitor the changes in temperature, air pressure, and humidity in the temperature-controlled room in real time, and the data is fed back to the processor.

[0058] S3. The processor dynamically adjusts the working status of the humidity control module based on real-time data to ensure that the humidity in the temperature-controlled room is maintained within the set range.

[0059] S4. End the test. The system will automatically shut down heating component 3, air pressure control module, humidity control module, etc.

[0060] The control system in this technical solution can achieve precise control and real-time monitoring of environmental parameters such as temperature, air pressure, and humidity in the temperature control room, ensuring the stability and reliability of the fan testing environment and improving the accuracy and repeatability of test results.
