Description

Technical Field

[0001] The present application relates to the technical field of reliability testing equipment, and in particular to a water vapor quality monitoring device and a temperature and humidity testing chamber. Background Art

[0002] At present, most products will undergo environmental adaptability tests during the development stage in order to explore and verify the reliability and durability of the products in different temperature, humidity and other environments. When conducting environmental adaptability tests, in order to realistically simulate the atmospheric environment or the use environment, a temperature and humidity test chamber will be used. The temperature and humidity test chamber is a device used to simulate and control environmental temperature and humidity, and is mainly used to test the performance and reliability of materials under different environmental conditions. It can simulate different environmental conditions such as high temperature, low temperature, high humidity, and low humidity. Its working principle is roughly as follows: the temperature and humidity test chamber consists of two parts: temperature control (heating and cooling) and humidification. Through the rotating fan installed on the top of the box, air is discharged into the box to realize gas circulation and balance the temperature and humidity in the box. The temperature and humidity sensors in the box collect data and transmit them to the temperature and humidity controller for editing and processing, and issue temperature and humidity control instructions. The adjustment is completed through the air heating unit, condenser and heating evaporation unit in the water tank.

[0003] The state or industry has clear requirements for the humidification water used in the temperature and humidity test chamber: the water used should be one of distilled water, deionized water, pure water or ultrapure water; the conductivity of the water used should not exceed 20us / cm. In traditional technology, a pure water machine is also installed at the water inlet of the test chamber to purify the tap water into pure water with a conductivity of 20us / cm or less. The pure water is then heated in the heater to produce water vapor. The water vapor is mixed with air in the fan and sent to the test chamber to participate in the test. However, this traditional test scheme cannot realize online monitoring of the quality of water vapor in the test chamber (such as pH value, conductivity value, etc.), and it is easy for the water quality to exceed the standard and affect the test results, causing corrosion damage to the product.

[0046] See also Figure 1 and Figure 4 , which is a temperature and humidity test box 100 shown in an embodiment of the present application, is used to test the reliability and durability of various products in environments with different temperatures, humidities, etc.

[0047] Exemplarily, the temperature and humidity test chamber 100 includes a test chamber 20, a humidification device 30 and a water vapor quality monitoring device 10. The test chamber 20 is the main structure of the temperature and humidity test chamber 100, providing a test site and being used to load the integrated humidification device 30 and the water vapor quality monitoring device 10.

[0048] The test box 20 may be in a cylindrical shape, a cubic shape, etc. A test chamber 21 is formed inside the test box 20 , and the test product is placed in the test chamber 21 to perform a temperature and humidity test.

[0049] Please continue reading Figure 1 The test box 20 includes a first side wall 22 and a second side wall 23 that are arranged opposite to each other, and a third side wall 24 connected between the first side wall 22 and the second side wall 23. The first side wall 22 is provided with an air inlet 221, and the second side wall 23 is provided with an air return port. The air inlet 221 and the air return port are both connected to the test chamber 21. The humidifying device 30 is connected to the air inlet 221 to introduce water vapor or a mixture of water vapor and air into the test chamber 21.

[0050] Please continue reading Figure 4For example, the humidification device 30 includes at least a water purifier 31, a water pipeline 32, a heater 33 and a second fan 34. The water pipeline 32 is used to connect tap water. The water purifier 31 and the heater 33 are installed in the water pipeline 32 in sequence along the flow direction of the tap water in the water pipeline 32. The tap water flows into the heater 33 after being purified by the water purifier 31. The heater 33 heats the pure water and vaporizes it into water vapor. The second fan 34 is arranged at the air inlet 221. The blades of the second fan 34 rotate to send water vapor or a mixture of air and water vapor into the test chamber 21.

[0051] The third side wall 24 is provided with a mounting through hole 241. The collection container 11, the condenser 121 and the sensor unit 123 extend into the interior of the test chamber 21 through the mounting through hole 241. In this way, the mounting structure of the water vapor quality monitoring device 10 is simplified.

[0052] On the basis of the above embodiment, the first side wall 22 and the third side wall 24 cooperate to form a windproof corner 25 , the water vapor quality monitoring device 10 is arranged close to the windproof corner 25 , and the water vapor quality monitoring device 10 and the air inlet 221 are staggered.

[0053] Specifically, the air inlet 221 is arranged in the middle position of the first side wall 22, and the windproof corner 25 is a right angle formed by the first side wall 22 and the third side wall 24. The water vapor quality monitoring device 10 is arranged close to the windproof corner 25, so that it can be staggered with the air inlet 221 to prevent the mixed gas of water vapor and air flowing in from the air inlet 221 from blowing directly onto the surface of the water vapor quality monitoring device 10.

[0054] Please continue reading Figure 1 The water vapor quality monitoring device 10 includes a collection container 11 and a quality monitoring module 12 .

[0055] A collecting chamber 111 is formed inside the collecting container 11, and a vent hole 112 is formed through the side wall of the collecting container 11. The vent hole 112 is used to connect the collecting chamber 111 with the external test chamber 21, so that the water vapor in the external test chamber 21 enters the collecting chamber 111 through the vent hole 112; the quality monitoring module 12 includes a condenser 121, a refrigeration unit 122, a sensor unit 123 and a process controller 124. The condenser 121 and the sensor unit 123 are respectively installed inside the collecting chamber 111. The condenser 121 is used to condense water vapor into condensed water, and the sensor unit 123 is used to detect the quality of the condensed water. The refrigeration unit 122 is connected to the condenser 121 to maintain the condenser 121 at a preset temperature for condensing water vapor into condensed water. The sensor unit 123 and the refrigeration unit 122 are respectively electrically connected to the process controller 124.

[0056] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the water vapor quality monitoring device 10 of this solution is applied to the temperature and humidity test box 100 to monitor the quality of water vapor in real time during the product test process; specifically, when in use, the collection container 11 is assembled with the quality monitoring module 12, and then the collection container 11 is extended into the test chamber 21 of the test box body 20, and the water vapor entering the test chamber 21 can flow into the collection chamber 111 through the vent holes 112 preset on the side wall of the collection container 11, and the refrigeration unit 122 performs refrigeration control on the condenser 121, so that the refrigeration The condenser 121 is maintained at a preset temperature that can condense water vapor into condensed water, so that the water vapor entering the collection chamber 111 is condensed into condensed water after contacting the condenser 121, and the condensed water is collected in the collection chamber 111. Then the sensor unit 123 can perform real-time detection of the quality of the condensed water, and transmit the detection result data to the process controller 124 in real time, so that the test personnel can timely and accurately grasp the quality of the water vapor, and then intervene in time when the water vapor has a problem of exceeding the water quality standard, so as to avoid the water quality exceeding the standard affecting the accuracy of the test results and prevent corrosion of the tested products.

[0057] It can be understood that, since condensed water is directly generated by condensation of water vapor and is not mixed with any other substances, the quality of water vapor can be characterized by indirectly detecting the quality of condensed water.

[0058] Please continue reading Figure 1 Furthermore, the temperature and humidity test chamber 100 also includes an operation screen 40 and a main controller 50, and the operation screen 40 and the process controller 124 are electrically connected to the main controller 50 respectively. Before the test begins, the test personnel can conveniently set the experimental parameters such as temperature and humidity in the test through the operation screen 40. The main controller 50 has pre-stored water quality standard values. After the main controller 50 receives the excessive data fed back by the process controller 124 and calculates and identifies that the excessive data exceeds the water quality standard value, it will issue an alarm prompt to promptly remind the test personnel to intervene and avoid the excessive water quality affecting the test results and products.

[0059] It is easy to understand that the main controller 50 is provided with an alarm module, which is used for alarm prompting. The alarm module can be any one of a sound alarm module, a light alarm module, an acousto-optic alarm module, etc., and can be flexibly selected according to actual needs.

[0060] Optionally, the operation screen 40 may be, but is not limited to, any one of a key screen, a touch screen, and the like.

[0063] Specifically, the mounting member 13 is fixed in the mounting through hole 241 by one of welding, riveting, clamping, bonding, etc., to provide a reliable and stable mounting foundation.

[0064] The mounting member 13 is provided with an internal thread structure, the first connecting member 113 is provided with a first external thread structure, and the second connecting member 125 is provided with a second external thread structure, and the first external thread structure and the second external thread structure are respectively threadedly connected with the internal thread structure. The threaded mounting method has high connection strength, and the installation and disassembly operations are convenient and labor-saving, which helps to reduce the installation difficulty of the collection container 11 and the quality monitoring module 12 and improve the test efficiency.

[0065] Of course, in other optional embodiments, the mounting member 13, the first connecting member 113 and the second connecting member 125 may also be installed by means of snap connection, magnetic connection, etc., which can be selected according to actual needs.

[0066] It is easy to understand that the mounting member 13 is specifically a nut, and the first connecting member 113 and the second connecting member 125 are specifically threaded sleeves.

[0067] In addition, based on any of the above embodiments, the collection container 11 includes an outer shell 114, an inner liner 115 and a first thermal insulation member 116, the outer shell 114 is sleeved on the outside of the inner liner 115 and cooperates to form a accommodating cavity, and the first thermal insulation member 116 is filled and arranged in the accommodating cavity; wherein the inner cavity of the inner liner 115 is set as a collection cavity 111.

[0068] Furthermore, the outer shell 114 is provided with a first opening for the inner liner 115 to be installed into the outer shell 114, and the inner liner 115 is provided with a second opening connected to the collection chamber 111. The collection container 11 also includes a second thermal insulation member, and the circumferential edge of the first opening is connected to the circumferential edge of the second opening through the second thermal insulation member.

The outer shell 114, the first heat insulating member 116 and the inner liner 115 can be supported and fixed on the test box 20 by assembling the first connecting member 113 and the mounting member 13. The first heat insulating member 116 is filled between the outer shell 114 and the inner liner 115, and the second heat insulating member is connected between the first opening and the second opening, so that a better heat insulation effect can be obtained, and the inner liner 115 is prevented from directly contacting the outer shell 114, resulting in heat transfer between the inner liner 115 and the outer shell 114, thereby ensuring the low temperature environment of the collection chamber 111, so that the water vapor can be effectively condensed into condensed water through the condenser 121.

[0070] For example, in the present application, the outer shell 114 is made of 316 stainless steel and is formed into a cylindrical shape with a diameter of about 13 cm, a length of 15 cm, and a wall thickness of 0.15 cm by a stamping process.

[0073] A third heat insulating member is provided between the sealing plug 117 and the wall of the vent hole 112. The third heat insulating member can improve the heat insulation performance at the vent hole 112, prevent heat from being transferred through the vent hole 112, ensure the heat insulation performance of the entire collection container 11, and obtain that the temperature in the collection cavity 111 of the inner liner 115 does not exceed 45°C when the outer shell 114 is in an environment of 150°C.

[0074] The third thermal insulation component may be, but is not limited to, thermal insulation sponge, thermal insulation glue, etc.

[0077] In the present application, the medium flowing through the condenser 121 is antifreeze, and the refrigeration unit 122 is used to refrigerate the antifreeze, so as to provide a low temperature for the condenser 121 when the antifreeze flows into the condenser 121. The freezing point of the antifreeze is lower than -70 degrees.

[0078] In one embodiment, the refrigeration unit 122 includes a refrigerator 122a, a circulation pipeline 122b and a circulation pump 122c. The refrigerator 122a and the circulation pump 122c are both arranged in the circulation pipeline 122b. The circulation pipeline 122b is connected with the medium inflow pipe 121b and the medium outflow pipe 121c. During the test, the antifreeze liquid circulates continuously in the circulation loop formed by the circulation pipeline 122b, the medium inflow pipe 121b, the condensation plate 121a and the medium outflow pipe 121c. The circulation pump 122c provides the power required for the flow of the antifreeze liquid. The refrigerator 122a cools down the high-temperature antifreeze liquid flowing out of the condensation plate 121a to ensure that the low-temperature antifreeze liquid continuously flows into the condensation plate 121a, so that the condensation plate 121a can obtain the ability to continuously condense water vapor.

[0079] The outer part of the circulation pipeline 122b is covered with an insulation layer, which has an insulation effect on the circulation pipeline 122b, ensures the low temperature state of the antifreeze liquid circulating inside, and prevents the temperature in the external environment from being transmitted to the antifreeze liquid through the wall of the circulation pipeline 122b and affecting the low temperature effect of the antifreeze liquid.

[0080] For example, the insulation layer may be, but is not limited to, insulation cotton, insulation foam, and the like.

[0081] Please continue reading Figure 1 Specifically, in one embodiment, the refrigerator 122a includes a cooling stack 1221a, a heat exchange plate 1222a, a first fan 1223a, and a heat dissipation fin 1224a. The cooling stack 1221a has a cold end and a hot end. For example, the cold end and the hot end are respectively located at two opposite ends of the cooling stack 1221a. The opposite ends can be as follows Figure 1 The upper and lower ends of the cooling stack 1221a in perspective.

[0082] The first fan 1223a and the heat dissipation fins 1224a are both disposed at the hot end, and the heat exchange plate 1222a is disposed at the cold end and communicated with the circulation pipeline 122b.

[0083] The cooling stack 1221a is the core component of the cooling unit 122 and is powered by direct current. The cooling stack 1221a includes a plurality of semiconductor cooling sheets, which are assembled into the cooling stack 1221a in series and parallel. When direct current is supplied, one end of the semiconductor cooling sheet becomes cold and the other end becomes hot, that is, one end of the cooling stack 1221a becomes a cold end and the other end becomes a hot end.

[0084] A heat sink fin 1224a with forced air cooling is installed at the hot end. After forced heat dissipation by the first fan 1223a, the temperature difference between the cold end and the hot end can be maintained at a low temperature of about 70°C. A heat exchange plate 1222a is tightly installed at the cold end to cool the antifreeze when it passes through the cold end of the refrigeration stack 1221a. The power of the refrigeration stack 1221a can be designed to be between 20W and 500W according to actual usage requirements.

[0085] In addition, based on any of the above embodiments, the quality monitoring module 12 further includes an exhaust valve 126, a liquid replenishing container 127 and a liquid discharge valve, and the exhaust valve 126, the liquid replenishing container 127 and the liquid discharge valve are respectively arranged in the circulation pipeline 122b.

[0086] When antifreeze is first added to the refrigeration unit 122, the air in the pipeline can be discharged to the outside through the exhaust valve 126 and the liquid replenishing container 127 to ensure the antifreeze filling effect. After the antifreeze is added, continuous pipeline exhaust is completed through the exhaust valve 126 during the circulation process.

[0087] The liquid replenishing container 127 is used to add antifreeze liquid to the circulation pipeline 122b to stabilize the sufficient flow of antifreeze liquid in the circulation pipeline 122b.

[0088] The drain valve is preferably installed at the lowest point of the circulation pipeline 122b, and is used to drain the antifreeze in the circulation pipeline 122b when the equipment is repaired.

[0089] In one embodiment of the present application, the sensor unit 123 includes a pH sensor 1231 and a conductivity sensor 1232, and the measuring heads of the pH sensor 1231 and the conductivity sensor 1232 are both inserted into the interior of the collection chamber 111. The pH sensor 1231 can be used to monitor the pH value of the condensed water in the collection chamber 111 in real time, and the conductivity sensor 1232 can monitor the conductivity value of the condensed water in the collection chamber 111 in real time, thereby feeding back the monitoring data to the process controller 124, and then uploading the detection results to the main controller 50 through the process controller 124, so as to accurately determine whether the current water quality exceeds the standard.

[0090] Furthermore, the sensor unit 123 also includes a first temperature sensor 1233 and a second temperature sensor 1234. The first temperature sensor 1233 is arranged in cooperation with the condenser 121 to detect the temperature of the condenser 121, and the second temperature sensor 1234 is arranged on the side wall of the collection chamber 111 and is used to detect the temperature of the condensed water. By real-time monitoring of the temperature of the condenser 121 and the condensed water, the refrigeration effect of the refrigeration unit 122 can be fed back to ensure that the device can be dynamically adjusted autonomously and operate in the optimal state.

[0091] Furthermore, the sensor unit 123 further includes a liquid level sensor 1235 , a measuring head of the liquid level sensor 1235 extends into the interior of the collection chamber 111 to perform real-time detection of the liquid level.

[0092] When the liquid level sensor 1235 detects that the water level in the collection chamber 111 reaches the first liquid level, the process controller 124 controls the sensor unit 123 to perform quality detection on the condensed water. The amount of condensed water collected corresponding to the first liquid level is appropriate, which helps to ensure the accuracy of quality detection.

[0093] When the liquid level sensor 1235 detects that the water level in the collection chamber 111 reaches the second liquid level, the process controller 124 controls the circulation pump 122c to extract the condensed water in the collection chamber 111. This prevents the condensed water from being collected in excess, causing the condensed water to submerge the condenser 121 and affect its normal operation.

[0094] When the liquid level sensor 1235 detects that the water level in the collection chamber 111 reaches the third liquid level, the process controller 124 controls the circulation pump 122c to stop pumping water, so as to ensure that there is space in the collection chamber 111 for continuously collecting water vapor.

[0095] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
