Description

Technical Field

[0001] The present invention relates to the field of fan testing, and particularly to a temperature control chamber for high-temperature testing of fans and its control system.

Background Art

[0002] In some subtropical countries, the climate is characterized by high temperature and high humidity throughout the year, with obvious seasonal variations. The average temperature in summer can reach 35 - 40 °C. This environment poses many challenges to the performance of fans. For example, aspects such as motor heat dissipation, thermal expansion and contraction adaptability of fan components, and service life are all severely tested. Therefore, fans used in this region often need to meet higher requirements. During the R & D and production processes, even if the manufacturer is in a country with a non-subtropical climate, a test environment can be set up to test the performance of the fan under specific temperature conditions to ensure that the fan can work properly in the actual working environment with drastic temperature changes, so as to adapt to the climate conditions of different regions.

[0003] However, traditional testing methods usually rely on the natural environment or simple heating equipment. These methods have many problems, such as overly long testing time and uncontrollable environmental conditions, resulting in unstable testing conditions and inaccurate test results. Therefore, developing a temperature control chamber suitable for testing the temperature conditions of fans is of great significance for improving the efficiency of fan testing and ensuring the accuracy of experimental results.

[0004] In view of the above technical problems, the present invention is specifically studied and proposed.

The hinge part includes a first hinge, a second hinge, a rotating shaft, and a positioning member. The first hinge is provided at one end of the support member, the second hinge is provided on the base, and the rotating shaft passes through the first hinge and the second hinge to realize the rotational connection of the support member relative to the base. The positioning member is used to limit the movement of the support member at a set position.

[0010] For a temperature control chamber for high-temperature testing of fans as described above, at least one fan assembly is provided inside the temperature control chamber body.

Specific implementation manner

[0032] The following will describe in detail the implementation manner of the present invention with reference to the accompanying drawings.

[0033] As Figure 1-7 shown, the present invention includes a temperature control housing for high-temperature testing of a fan, including a controller 1, a temperature control housing 2, a heating component 3, and a door 21 that is opened and closed on the side wall of the temperature control housing 2 and forms an open or closed space with the temperature control housing 2. It also includes a plurality of temperature sensors 4 disposed inside the temperature control housing 2 and electrically connected to the controller 1 and used for monitoring the temperature change in the temperature control housing. At least one air flow control valve 7 for balancing the air pressure inside the temperature control housing 2 is provided on the side wall of the temperature control housing 2. A plurality of air outlets 22 are provided inside the temperature control housing 2. The heating component 3 includes a main heating assembly 31 disposed at the top of the temperature control housing 2 and used for sucking air and heating it to a target temperature. The main heating assembly 31 is connected with a plurality of output ends, and the output ends are communicated with the air outlets 22. The controller 1 is electrically connected to the heating component 3 and is used for controlling the operation of the heating component 3.

[0034] The controller 1 is electrically connected to the heating component 3 and is used for precisely controlling the working state of the heating component 3. The temperature sensor 4 is electrically connected to the controller 1 to realize real-time monitoring of the temperature change in the temperature control housing and feed the temperature data back to the controller 1. The controller 1 adjusts the working state of the heating component 3 according to the fed-back temperature data to ensure that the temperature in the temperature control housing is maintained within the set target temperature range. The main heating assembly 31 includes a fan and a heating element. After the fan sucks in air, when the air passes through the heating element, electrical energy is converted into heat energy, thereby heating the air to the set temperature. The heated air is sent into the temperature control housing through the output end of the fan, thereby raising the temperature in the temperature control housing. The main heating assembly 31 is arranged at the top of the temperature control housing 2. The output end of the fan can be directly communicated with the air outlet 22 or can be communicated with the air outlet 22 through the delivery pipe 23, and can evenly distribute the heated air in the temperature control housing. It should be noted that the heating element can be an electric heating wire or an electric heating film, which belongs to the prior art.

[0035] This application can precisely control the working state of the main heating component 31, thereby ensuring that the fan can perform performance tests under set temperature conditions. Meanwhile, the air flow 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 air flow inside the temperature control chamber 2 and avoiding the influence of air pressure changes on the test results.

[0036] Place the fan or component to be tested inside the temperature control chamber 2. In a high-temperature environment, observe the operating state and performance of the fan, such as indicators like rotational speed changes, noise, and heat dissipation effect. During the test, it is necessary to ensure the stability of the test environment temperature and avoid the influence of temperature fluctuations on the test results. After the test, it is necessary to comprehensively detect the performance of the fan, including rotational speed, noise, heat dissipation effect, etc. If a performance decline or abnormality is found, it helps technicians further analyze the reasons and take corresponding improvement measures. It should be noted that the temperature control chamber is also equipped with a cooling component (not shown in the figure) to enable the temperature control range of the temperature control chamber to be between minus 100 degrees Celsius and 200 degrees Celsius; this temperature control range can not only meet the test requirements in high-temperature environments in subtropical regions but also be applicable to experimental and test scenarios under various extreme temperature conditions; therefore, the temperature control chamber of the present invention is not limited to the test conditions required for subtropical regions but can be widely applied to various occasions requiring precise temperature control.

[0037] By precisely controlling the temperature conditions of the temperature control chamber, this application can create a stable test environment in a relatively short time, significantly improving the fan test efficiency. Meanwhile, the precise temperature control and real-time monitoring functions ensure the accuracy of the test results, providing reliable data support for the research and development and production of fans.

[0038] As Figure 1-7 shown, as a further technical solution of this application, there are two groups of air outlets 22. One group of air outlets 22 is directly connected to the output end, and there is a delivery pipe 23 between the other group of air outlets 22 and the output end. The delivery pipe 23 extends from the output end into the interior of the temperature control chamber 2 and is connected to the air outlet 22. The heating component 3 further includes an auxiliary heating component 32 for radiating heat energy into the interior of the temperature control chamber 2. The auxiliary heating component 32 is composed of several heating sheets, and the several heating sheets are evenly laid flat in the inner side wall of the temperature control chamber 2.

[0039] According to Bernoulli's principle, when the fan to be tested is running, a low-pressure area will be generated on the air inlet side and a high-pressure area will be generated on the air outlet side. This pressure difference is the driving force for the formation of air flow. The rotation of the fan increases the air flow, resulting in slight fluctuations in the local temperature. If the rotation speed of the fan changes, more obvious temperature changes will occur. Therefore, the auxiliary heating component 32 on the inner layer of the temperature control housing 2 has its heating temperature controlled by the controller 1. Since multiple heating elements are arranged in a tiled manner inside the temperature control housing 2 and radiate heat energy into the temperature control housing 2 simultaneously, the air within the corresponding area range is heated. The controller 1 performs feedback regulation based on the data collected by the temperature sensor 4, thereby being able to adjust the heat radiated by the auxiliary heating component 32 into the temperature control housing 2. Further, several heating elements are electrically connected in parallel with the controller 1 and can be controlled individually or work in cooperation by the controller 1. By setting the auxiliary heating component 32 in this way, the air flow in a specific area can be heated, so that the air temperature inside the temperature control housing 2 remains at the set temperature and tends to be uniform.

[0040] As Figure 1-7 shown, as a further technical solution of the present application, in order to ensure that the temperature sensor 4 can be stably and flexibly installed inside the temperature control housing 2 and its position and angle can be adjusted as needed, a connecting portion 41 for fixing the temperature sensor 4 is provided inside the temperature control housing 2. The connecting portion 41 includes at least one support member 42, a base 43, and a hinge portion 44. The base 43 is fixed on the side wall of the temperature control housing 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 the hinge portion 44. The hinge portion 44 includes a first hinge 441a, a second hinge 441b, and a positioning member 443. The first hinge 441a is provided at one end of the support member 42, the second hinge 441b is provided on the base 43, and a rotating shaft 442 passes through the first hinge 441a and the second hinge 441b to achieve the rotational connection of the support member 42 relative to the base 43. The positioning member 443 is used to limit the movement of the support member 42 at the set position. The temperature sensor 4 is connected inside the temperature control housing 2 through the connecting portion 41 and rotates relative to the base 43 through the hinge portion 44, thereby adjusting the angle of the temperature sensor 4. Specifically, as Figure 5 、 Figure 6As shown, one end of the positioning member 443 is sleeved on the corresponding position of the second hinge 441b, and the two are in relative rotational fit. The other end is provided with a chute and a plurality of clamping grooves. When the first hinge 441a changes its position relative to the second hinge 441b, it can move in the chute and be limited to the current position through the clamping grooves, so as to realize the rotational movement and positioning between the support member 42 and the base 43. Correspondingly, positioning columns are provided on both the first hinge 441a and the second hinge 441b to cooperate with the positioning member 443 to prevent the positioning member 443 from detaching. The structure is simple and the operation is convenient. In this application, the temperature sensor 4 can be adjusted and fixed through the connecting portion 41. Without interfering with the operation of the fan to be measured, the temperature monitoring can be realized at different positions. Compared with the traditional temperature sensor 4 externally connected to the wall, it avoids the interference of the fan airflow caused by the improper installation position of the temperature sensor 4, ensures both the flexibility of the installation of the temperature sensor 4 and that the temperature sensor 4 will not be displaced by airflow or other external forces during the test, thereby improving the accuracy and reliability of the test results.

[0041] As Figure 1-7 described, as a further technical solution of the present application, the support member 42 includes a first arm section 421 and a second arm section 422 nested and connected to one end of the first arm section 421. The first arm section 421 and the second arm section 422 can slide relative to each other. The support member 42 further includes a locking device 423. The locking device 423 is used to stretch or contract the first arm section 421 and the second arm section 422 to a target position and keep them fixed at the current position. The locking device 423 is a clamping structure. The support member 42 is provided with a hollow structure. A guide rail is provided on the inner wall of the first arm section 421, and a slider is correspondingly provided on the outer wall of the second arm section 422. The slider cooperates with the guide rail to realize the relative sliding of the first arm section 421 and the second arm section 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, and 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 perform telescopic movement in the ray direction of the currently fixed angle. The clamping structure includes a number of hole positions located on the first arm segment 421, and the number of hole positions is distributed along the length direction of the first arm segment 421. It also includes a protrusion located on the second arm segment 422 and capable of telescoping. The protrusion is adapted to the size of the hole position. When the support member 42 is in a locked state, press the protrusion to a position where it does not block the movement of the second arm segment 422, and at the same time move the second arm segment 422 forward or backward to telescope the second arm segment 422, thereby adjusting the telescopic amount between the first arm segment 421 and the second arm segment 422. During the telescoping process, the protrusion is always squeezed. When reaching the next hole position, the protrusion automatically rebounds to stop the movement between the first arm segment 421 and the second arm segment 422, and the support member 42 is adjusted to the required length in turn. When it is necessary to adjust the monitoring position of the temperature sensor 4, the user stretches or contracts the support member 42 and fixes it at the required position by using the locking device 423 to adapt to the telescopic movement of the support member 42. The structure is simple and the operation is convenient. It should be noted that the sliding fit mode of the slider and the guide rail is a prior art and is a technical means that can be understood by those skilled in the art.

[0043] At the same time, the interior of the support member 42 is hollow to allow wires to pass through for connecting the temperature sensor 4. In addition, a fixing portion for fixing the temperature sensor 4 is provided at one end of the second arm segment 422 away from the first arm segment 421, and the structure is reliable and convenient to use.

[0044] As Figure 1-7 shown, as a further technical solution of the present application, at least one fan assembly 5 is provided inside the temperature control housing 2, and the fan assembly 5 is used to disturb the air flow inside the temperature control housing 2 to strengthen the air flow. When the test piece is a stationary fan or component, the flow rate is relatively large at the position close to the air outlet 22, and an air pressure difference is easily formed. This technical solution uses the air pressure difference to drive the air flow inside the temperature control housing, provides a driving force for the fan assembly 5, makes the fan assembly 5 rotate and further disturbs the air flow inside the temperature control housing 2, which helps to evenly distribute the hot air inside the temperature control housing.

[0045] As Figure 2 、 Figure 3As shown, as a further technical solution of the present application, the temperature control housing 2 further includes a support assembly 6. The support assembly 6 includes at least one set of symmetrically arranged upright supports 61, and a horizontal support rod 62 is arranged between the upright supports 61. In the present application, there are two sets of symmetrically arranged upright supports 61 connected to the horizontal support in a matching manner, and both are fixedly connected to the temperature control room by means of fasteners (which are prior art), which helps to enhance the structural stability of the temperature control room. This structure can not only support the temperature control room, but also provide a position for installing the test piece, improving the space utilization rate of the temperature control room. Further, the inside of the support assembly 6 is a hollow structure to supply power for the wires to be routed along the inside of the support assembly 6, avoiding the exposure of the wires outside, reducing the interference of the wires on the air flow, and at the same time improving the neatness and safety of the wiring.

[0046] As Figure 3 shown, further, an insulating sleeve 231 for isolating the heat exchange between the inside of the conveying pipe 23 and the external environment is provided on the outer layer of the conveying pipe 23. In practical applications, the insulating sleeve 231 can be made of insulating materials such as fiberglass and polyurethane foam. These materials have good heat insulation performance and durability. The insulating sleeve 231 can be installed on the outer layer of the conveying pipe 23 by means of wrapping, winding or fixing to ensure that it fits tightly and will not loosen due to air flow vibration. This technical solution can effectively prevent the hot air in the conveying pipe 23 from being cooled by the outside world, resulting in a temperature drop, and ensure the temperature uniformity and stability in the temperature control room.

[0047] As Figure 2 shown, specifically, the present application also includes an observation window 24 provided on the door 21 for observing the inside of the temperature control housing 2 from the outside, and a high-temperature resistant lamp 25 for lighting is also provided inside the temperature control housing 2. The observation window 24 is made of a transparent material and can withstand the high-temperature environment inside the temperature control housing 2, ensuring that the operator can safely and clearly observe the internal test process. The design of the observation window 24 not only improves the transparency of the test, but also enhances the convenience of operation, enabling technicians to monitor the internal test status in real time without entering the temperature control housing 2. In addition, the high-temperature resistant lamp 25 provided inside the temperature control housing 2 can ensure that there is sufficient light inside the temperature control housing 2 during the test, facilitating the observation and recording of test data.

[0048] In order to improve the operation flexibility of the temperature control room, a video monitor 9 (not shown in the figure) is also provided in the temperature control housing 2. The video monitor 9 is electrically connected to the controller 1 and can remotely monitor the operation status inside the temperature control housing 2 through the controller 1. In addition, the video monitor 9 also has a data storage function and can record and store the monitoring data so that the staff can view the historical monitoring information at any time, analyze abnormal situations and make early warning predictions.

[0049] As Figure 1 andFigure 2 As shown, further, the temperature-controlled chamber further includes a heat-insulating bottom plate 71 for preventing heat from dissipating from the ground. The heat-insulating bottom plate 71 is hermetically connected to the bottom of the temperature-controlled chamber body 2, effectively preventing the hot air inside the temperature-controlled 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-controlled chamber for fan high-temperature testing, including the above-mentioned temperature-controlled chamber for fan environmental 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 user's touch operation; 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 inside the temperature-controlled chamber body 2, so as to make the temperature inside 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 inside the temperature-controlled chamber body 2; the pressure control module is electrically connected to the processor and is used to control and adjust the air pressure inside the temperature-controlled chamber body 2; the abnormal warning module is used to issue a warning when an abnormality occurs in the internal environment of the temperature-controlled chamber body 2.

[0051] The temperature sensors 4 are distributed at different positions inside the temperature-controlled chamber body 2, and are used to monitor the temperature conditions inside the temperature-controlled chamber body 2 in real time. When the ambient temperature inside the temperature-controlled chamber body 2 exceeds the set temperature value, cooling treatment is performed, and when the ambient temperature inside the temperature-controlled 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 inside the temperature-controlled chamber. In addition, these modules can also work together through the processor to achieve multi-parameter linkage control to meet the diverse requirements 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-controlled chamber has stronger adaptability and can meet the requirements of various complex test scenarios.

[0052] In order to improve the operation flexibility of the temperature-controlled chamber, a video monitor 9 (not shown in the figure) electrically connected to the controller 1 is further provided in the temperature-controlled chamber body 2. The video monitor 9 is electrically connected to the processor, and can monitor the operation status inside the temperature-controlled 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 temperature-controlled chamber monitored historically, thereby analyzing abnormal situations and making early warning predictions.

[0053] Specifically, the air pressure control module includes an air pressure sensor 831 and an air flow control valve 7. The air pressure sensor 831 is used to monitor the air pressure inside the temperature control chamber 2, and the air flow control valve 7 is used to supplement or extract air into the temperature control chamber, so as 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 a processor to 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 is used to monitor the humidity inside the temperature control chamber 2, and the spray assembly is used to increase the air humidity. The humidity control module controls the humidity inside the temperature control chamber 2 through a processor to meet the test conditions. The spray assembly is arranged below the fan near the air outlet 22. By using the hot air output by the fan, the tiny particles atomized by the spray assembly are evenly distributed in the temperature control chamber along with the flowing air. At the same time, the abnormal warning module is provided with a buzzer or an indicator light, which helps the staff to detect and handle abnormal situations in time and ensure the safety of the test process.

[0055] The control process of the temperature control chamber for fan environment testing is as follows:

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