Description

Technical Field

[0001] This application belongs to the technical field of experimental chambers, and particularly relates to a humidity experimental device. Background Art

[0002] A humidity experimental chamber can be used as test equipment for humidity tests, mainly for generating a humidity condition for various materials or products to conduct corrosion resistance, reliability, accelerated life and other tests.

[0003] The existing humidity experimental chamber heats the water in the boiler to make the water boil and evaporate into the experimental chamber to achieve the purpose of humidification. When the water in the boiler evaporates to a certain level, the water from the water source is pumped into the boiler by a water pump. However, the water in the water source is usually normal temperature water, while the water temperature in the boiler is relatively high. Therefore, this water replenishment method will cause a drastic fluctuation in the water temperature in the boiler, resulting in unstable humidification amount and further unstable humidity in the experimental chamber.

[0037] An embodiment of the present application provides a humidity experiment device. Based on this, it can alleviate the situation that the humidity in the experimental chamber is unstable during water replenishment. See the following for details.

[0038] Next, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments described herein.

[0039] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a humidity experiment device, which includes an experimental chamber 10, a heating box 20, a first water box 30, a second water box 40, and a third water box 50. The following is a detailed description:

[0040] The experimental chamber 10 is used to place experimental samples for humidity experiments. Specifically, the humidity inside the experimental chamber 10 can be controlled to simulate a humidity environment, so as to test the corrosion resistance, reliability, accelerated life, etc. of the experimental samples located inside the experimental chamber 10. Specifically, the experimental chamber 10 can be a rectangular box body.

[0041] The heating box 20 is connected to the experimental chamber 10 and is used to heat the water inside it into water vapor and send it into the experimental chamber 10 to generate corresponding humidity inside the experimental chamber 10. Specifically, the heating box 20 can be a boiler or the like.

[0042] The first water box 30 is used to hold water. The first water box 30 can be used as a water source to supply water to other water boxes.

[0043] The second water box 40 is located above the first water box 30 and is connected to the heating box 20 through the first pipeline 41.

[0044] The third water box 50 is located above the second water box 40 and is connected to the second water box 40 through the second pipeline 52. A flow control switch 521 is provided in the second pipeline 52. The third water box 50 is also connected to the first water box 30 through the third pipeline 53, and a water pump 531 is provided in the third pipeline 53.

[0045] The horizontal heights of the first water box 30, the second water box 40, and the third water box 50 increase in sequence, and all can be of a rectangular hollow box body structure.

[0046] In this embodiment, the water in the first water box 30 is used as the water source. The water pump 531 is used to pump the water in the first water box 30 along the third pipeline 53 to the third water box 50. Since the third water box 50 is higher than the second water box 40, the water in the third water box 50 flows into the second water box 40 along gravity through the second pipeline 52. Among them, the flow control switch 521 can be used to adjust the flow rate in the second pipeline 52 so that the water in the third water box 50 slowly flows into the second water box 40. Since the second water box 40 is connected to the heating box 20 through the first pipeline 41, the water in the second water box 40 flows into the heating box 20 through the first pipeline 41. And because the water in the third water box 50 slowly flows into the second water box 40, and the second water box 40 is connected to the heating box 20, the third water box 50 buffers by slowly adding water to the second water box 40, and then supplies water to the heating box 20 through the second water box 40, which can alleviate the problem that the water in the heating box 20 fluctuates violently due to excessive single water replenishment, resulting in unstable humidification amount, thereby alleviating the unstable humidity situation inside the experimental chamber 10.

[0047] Specifically, the slow flow switch 521 can be structured as a needle valve, a throttle valve, etc. Taking the needle valve as an example for illustration, the needle valve has a slender needle-shaped valve core. The valve core is inserted into the valve seat to form a narrow flow passage, and the position of the valve core can be adjusted by rotating the handwheel. By rotating the handwheel, the depth of the needle-shaped valve core inserted into the valve seat is adjusted, changing the cross-sectional area of the flow passage, thereby controlling the flow rate within the slow flow switch 521.

[0048] It should be noted that by adopting the water replenishing method in the embodiment of the present application, the humidity fluctuation within the humidity test chamber 10 can be kept within + / - 0.1% RH (Relative Humidity), greatly reducing the humidity fluctuation within the test chamber 10.

[0049] In an alternative embodiment, the bottom of the heating box 20 is flush with the bottom of the second water box 40. The two ends of the first pipeline 41 are respectively connected to the bottom of the heating box 20 and the bottom of the second water box 40, so that the liquid levels in the heating box 20 and the second water box 40 are flush.

[0050] It can be understood that when the heating box 20 and the second water box 40 are connected through a pipeline and their bottoms are at the same horizontal height, under the same external atmospheric pressure and the action of gravity, the liquids in the heating box 20 and the second water box 40 will automatically adjust to the same liquid level height. Because under the action of gravity, the liquid will flow from the container with a higher liquid level to the container with a lower liquid level until the liquid level heights of the two containers are the same. When water is slowly fed into the second water box 40 through the second pipeline 52 in the third water box 50, it is equivalent to simultaneously adding water to the third water box 50. In this embodiment, through slow water replenishment and the second water box 40 as a buffer, the water temperature in the heating box 20 is ensured to be relatively stable, thereby ensuring the humidity stability within the test chamber 10.

[0051] In an alternative embodiment, the second water box 40 is also connected to the first water box 30 through an overflow pipe 42. The first end of the overflow pipe 42 is connected to the top of the first water box 30, the second end of the overflow pipe 42 is connected to the bottom of the second water box 40, and at least a part of the second end of the overflow pipe 42 protrudes from the bottom of the second water box 40.

[0052] When the liquid level height of the second water box 40 is lower than the height of the part of the overflow pipe 42 protruding from the bottom of the second water box 40, water will not flow into the second water box 40 through the overflow pipe 42;

[0053] To avoid water shortage in the second water box 40, in practical applications, the water filling rate of the third water box 50 to the second water box 40 is usually greater than the water consumption rate of the heating box 20. Therefore, the liquid level height in the second water box 40 will gradually rise. When the liquid level height exceeds the height of the overflow pipe 42 protruding from the bottom of the second water box 40, the excess water will flow into the first water box 30 along the overflow pipe 42, avoiding the situation of water overflow caused by excessive water replenishment.

[0054] In an alternative embodiment, the second water box 40 is also connected to the first water box 30 through a fourth pipeline 44. A switching valve 441 is provided on the fourth pipeline 44, and the switching valve 441 is used to control the opening and closing of the fourth pipeline 44. Specifically, the two ends of the fourth pipeline 44 are respectively connected to the bottom of the second water box 40 and the top of the first water box 30.

[0055] When the humidity test is completed or the water box needs to be maintained, the switching valve 441 can be opened to make the fourth pipeline 44 unobstructed, so that the water in the second water box 40 can flow back to the first water box 30 along the fourth pipeline 44. And since the third water box 50 and the heating box 20 are both connected to the second water box 40, the water in the third water box 50 and the heating box 20 will also gradually flow back to the first water box 30 through the second water box 40, thereby emptying the water in the second water box 40, the third water box 50 and the heating box 20. Just close the switching valve 441 during the humidity test.

[0056] In an alternative embodiment, the humidity experiment device further includes a liquid level sensor 55. The liquid level sensor 55 is located in the third water box 50, and the liquid level sensor 55 is used to obtain the liquid level height of the third water box 50. When the liquid level height in the third water box 50 is lower than the preset liquid level height, the water pump 531 pumps the water in the first water box 30 along the third pipeline 53 to the third water box 50.

[0057] When the liquid level height is lower than the preset value, the water pump 531 is started. When the liquid level height is higher than the preset value, the water pump 531 stops. It can be understood that the preset liquid level height at which the water pump 531 starts can be the first preset height, and the preset liquid level height at which the water pump 531 stops can be the second preset height. The first preset height and the second preset height are different, so as to replenish water to the third water box 50 when it is lower than the first preset height and stop replenishing water when it is higher than the second preset height, so that the liquid level of the third water box 50 is maintained between the first preset height and the second preset height, effectively reducing the number of water replenishments, and at the same time ensuring that there is sufficient water in the third water box 50 to supply other water boxes.

[0058] Next, an exemplary description of a relatively optimal embodiment structure of the humidity experiment device will be given:

[0059] A liquid level sensor 55 is installed in the third water box 50, and the third water box 50 is connected to the first water box 30 through a third pipeline 53. A water pump 531 is installed in the third pipeline 53. When the water level in the third water box 50 drops to a second preset height, the liquid level sensor 55 triggers the water pump 531 to work, pumping the water in the first water box 30 into the third water box 50 until the third water box 50 reaches the first preset height, triggering the water pump 531 to stop pumping water.

[0060] The bottom of the third water box 50 is connected to the top of the second water box 40 through a second pipeline 52. A flow control switch 521 is provided in the second pipeline 52, enabling the water in the third water box 50 to flow continuously and slowly to the heating box 20 through the flow control switch 521.

[0061] The second water box 40 is communicated with the first water box 30 through an overflow pipe 42. The water in the second water box 40 that is higher than the port of the overflow pipe 42 can flow back to the first water box 30 through the overflow pipe 42.

[0062] The bottom of the heating box 20 is connected to the bottom of the second water box 40 through a first pipeline 41, ensuring that the water level height in the heating box 20 is the same as that in the second water box 40.

[0063] Among them, the water flow rate through the flow control switch 521 is greater than the water consumption in the heating box 20, which can always ensure that there is water in the second water box 40 flowing into the first water box 30 through the overflow pipe 42, thereby ensuring the stability of the water level height in the second water box 40 and indirectly ensuring the stability of the water level height in the heating box 20.

[0064] The water in the third water box 50 continuously flows to the second water box 40. Since the liquid level sensor 55 controls the water pump 531 to replenish water, it can ensure that there is always water flowing from the third water box 50 to the second water box 40. At the same time, the water consumed in the heating box 20 is continuously replenished through the second water box 40 to achieve automatic water replenishment for the dynamic balance of the heating box 20.

[0065] When the experiment in the experimental box 10 is completed, all the water in the second water box 40, the third water box 50, and the heating box 20 can be emptied by opening the switch valve 441 in the fourth pipeline 44. The above is the description of the structure and water replenishment principle of this preferred embodiment.

[0066] In an alternative embodiment, the experimental box 10 is a rectangular box body, and the box body includes opposite first side walls 11, second side walls 12, a top wall 13, and a bottom wall 14. A baffle 15 is bridged between the first side walls 11 and the second side walls 12. The baffle 15 is spaced from both the top wall 13 and the bottom wall 14. The baffle 15 and the first side wall 11 enclose an adjustment channel 17.

[0067] The adjustment channel 17 can guide the air to circulate inside the experimental chamber 10. By controlling the air flow path, it is possible to ensure a uniform distribution of humidity inside the experimental chamber 10 and avoid local areas with too high or too low humidity. At the same time, the adjustment channel 17 can also prevent the water vapor from directly blowing on the experimental sample, thus providing a more uniform test environment.

[0068] Furthermore, in this embodiment, as Figure 2 shown, the heating box 20 can be arranged on the bottom wall 14 of the box body and is located below the adjustment channel 17.

[0069] Hot air has the property of natural upward movement. By arranging the heating box 20 at the bottom, it is easier for the water vapor generated by heating in the heating box 20 to diffuse upward and be evenly distributed throughout the experimental chamber 10.

[0070] The heating box 20 is located at the bottom of the box body and below the port of the adjustment channel 17, which can prevent cold air from directly contacting the heating box 20, thereby reducing the formation of condensed water in the heating box 20. Condensed water may affect the normal operation of the experimental sample and equipment, and reducing condensation helps to maintain the stability of the experimental environment.

[0071] In this embodiment, the humidity experimental device may further include a dehumidifier 171. The dehumidifier 171 is located inside the adjustment channel 17, and the dehumidifier 171 is used to dehumidify the air inside the experimental chamber 10.

[0072] The dehumidifier 171 can work in cooperation with the heating box 20 to achieve precise control of the humidity inside the experimental chamber 10. When the water vapor output by the heating box 20 is excessive, the excessive water vapor can be removed by the dehumidifier 171 to keep the humidity inside the experimental chamber 10 within a preset range, thereby reducing experimental errors. Specifically, the dehumidifier 171 can be a condensation dehumidifier 171, a rotary dehumidifier 171, etc.

[0073] Furthermore, in this embodiment, the humidity experimental device further includes a heater 173. The heater 173 is located inside the adjustment channel 17 and above the dehumidifier 171, and the heater 173 is used to heat the air inside the experimental chamber 10.

[0074] The heater 173 can be used to adjust the air temperature inside the experimental chamber 10. By adjusting the temperature, different environmental conditions can be simulated to make the experiment more diverse and accurate.

[0075] In addition, when the dehumidifier 171 removes moisture from the air, it may lower the air temperature. The heater 173 can compensate for this cooling effect, keep the temperature inside the experimental chamber 10 stable, and prevent the experimental sample from being affected by excessive cooling.

[0076] Furthermore, the humidity experiment device further includes a circulation fan 175, which is located within the experiment chamber 10 and above the heater 173, and is used to direct the air flow within the experiment chamber 10.

[0077] The circulation fan 175 can direct the air flow within the experiment chamber 10, ensuring that the heated air and humidity are evenly distributed throughout the experiment chamber 10, and avoiding the phenomenon of uneven temperature and humidity in local areas. Moreover, the circulation fan 175 can accelerate the exchange rate between the air and the water vapor generated by the dehumidifier 171, the heater 173, and the heating box 20, enhancing the air humidity exchange and heating effects within the experiment chamber 10, and enabling the temperature and humidity within the experiment chamber 10 to reach the set values faster.

[0078] Moreover, promoting air flow through the circulation fan 175 can reduce the temperature and humidity gradients within the experiment chamber 10, making the experimental environment more stable and consistent, and improving the accuracy and repeatability of the experimental results.

[0079] It should be noted that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application. The orientation terms "inner" and "outer" refer to the inside and outside relative to the contour of each component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the relative spatial descriptions used here.

[0080] It also needs to be noted that in the present application, the so-called "one embodiment", "another embodiment", "embodiment", etc. refer to the specific features, structures, or characteristics described in connection with that embodiment being included in at least one embodiment generally described in the present application.
