Abstract
Description
Technical Field
[0001] This invention relates to a high-temperature immersion testing device for automotive parts, belonging to the field of motor vehicle testing technology. Background Technology
[0002] For a certain type of automotive components, such as NTC temperature acquisition probes and other electronic products, as well as various seals, in order to determine their stability under special high-temperature environments for long-term use, they need to be immersed in high-temperature liquids at 60-85°C for 800-1500 hours. Such tests, in addition to ensuring the continuity of heating, must also ensure that the immersion liquid is not affected by external factors and that the liquid used is always kept at a specific quantity.
[0003] Because the testing period is too long (generally 4-6 months), it is very difficult to manually monitor and maintain the liquid level for a long time. If the liquid evaporates excessively due to negligence, the test may fail and all previous tests will be invalidated and need to be repeated, resulting in a waste of time. This not only reduces work efficiency but also delays the time when customers urgently need to obtain test results, causing losses to customers' R&D or production.
[0004] In addition, it is not difficult to implement to simply set up a water level monitoring and alarm mechanism in the container in the test device. The problem is that during such a long test, there needs to be personnel on-site at all times to ensure that water can be replenished in time when the equipment alarms. If the personnel on duty are not on-site, the problem of water shortage in the container cannot be solved in time even if an alarm is triggered, which will still lead to the test being invalid. Summary of the Invention
[0005] The technical problem to be solved by this invention is: how to ensure that the soaking liquid is not affected by external factors and that the liquid used is always automatically maintained at a specific amount, while ensuring continuous heating.
[0006] To address the above problems, the technical solution proposed by this invention is as follows: A high-temperature immersion test device for the durability of automotive components includes a heating container, an immersion container, and an automatic liquid replenishment system. The heating container has an upward-facing opening and an internal electric heating component. The immersion container is designed to be placed inside the heating container at least from the bottom, and at least the bottom is made of a thermally conductive material. The top has an upward-facing opening. In application, the immersion container contains a liquid (first type), the device under test is placed in the liquid (first type), the heating container contains a liquid (second type) that submerges the electric heating component, and the lower part of the immersion container is placed inside the heating container and in contact with the surface of the liquid (second type) in the heating container. Throughout the immersion process, the electric heating component continuously supplies heat, and the automatic liquid replenishment system replenishes the liquid in both the heating container and the immersion container in real time.
[0007] The soaking container has a rim around its outer periphery. After the heating container is placed in the lower part of the soaking container, the rim can press against the top edge of the opening of the heating container, so that the entire soaking container can cover the opening of the heating container. The air pressure inside the covered heating container is atmospheric pressure.
[0008] The bottom of the soaking container is provided with a heat-conducting plate that evenly transfers heat into the soaking container. The heat-conducting plate has a set thickness, and only the heat-conducting plate of the soaking container is immersed in the liquid.
[0009] The soaking container has a cap for covering its opening, and the pressure inside the soaking container covered by the cap is atmospheric pressure.
[0010] The central area of the cover has an operating hole that is open at both the top and bottom, and is equipped with various wire-passing covers that can cover the operating hole. Electrical wires can be forcefully passed through the wire-passing covers, which are made of elastic material that can automatically close after being perforated.
[0011] The automatic liquid replenishment system includes a storage container, a liquid level equalization container one, a liquid level equalization container two, a connecting pipe one connecting the liquid level equalization container one to the soaking container, and a connecting pipe two connecting the liquid level equalization container two to the heating container. The liquid one and liquid two are the same liquid. In application, the liquid level equalization container one contains liquid one, which has a liquid level equal to the height of liquid level one. In application, the liquid level equalization container two contains liquid two, which has a liquid level equal to the height of liquid level two. The liquid level equalization container one and the liquid level equalization container two are respectively provided with overflow hole one and overflow hole two, which determine the height of liquid level one and liquid level two, respectively. The liquid stored in the storage container can automatically flow into the liquid level equalization container one and the liquid level equalization container two. The liquid level equalization container one and the liquid level equalization container two are respectively provided on the upper part of the liquid level equalization container one and the liquid level equalization container two.
[0012] Overflow hole 1 is connected to liquid level container 2 through a flow pipe. The liquid stored in the storage container first flows into liquid level container 1. The liquid flowing out of overflow hole 1 of liquid level container 1 flows into liquid level container 2 through the flow pipe, so that the storage container supplies water to liquid level container 1 and liquid level container 2 in series.
[0013] A drip valve is installed on a container with the same liquid level as container one. The upper end of the drip valve is connected to a storage container through a liquid supply pipe, and the lower end is connected to a drip pipe one inserted into container one with the same liquid level as container one. The drip valve controls the drip supply of liquid to container one with the same liquid level as container one through the drip pipe one. A drip pipe two is installed at the top of container two with the same liquid level as container two and is inserted into container two with the same liquid level as container two. The upper end of drip pipe two is connected to a cross-flow pipe, and drip supply of liquid to container two with the same liquid level as container two through drip pipe two.
[0014] The automatic liquid replenishment system also includes a liquid replenishment and supply mounting frame. The first liquid level container and the second liquid level container each have a fixed base plate and a fixed base plate, respectively. The first liquid level container and the second liquid level container are fixed on the fixed base plate and the fixed base plate, respectively. Permanent magnets are provided in both the fixed base plate and the fixed base plate. An iron positioning plate is provided on the liquid replenishment and supply mounting frame. The first liquid level container and the second liquid level container are respectively attracted to the iron positioning plate through the fixed base plate and the fixed base plate. The liquid storage container is installed on the liquid replenishment and supply mounting frame above the iron positioning plate.
[0015] The automatic liquid replenishment system also includes a uniform distributor, which comprises a collection chamber and multiple equal-spaced, radially arranged distribution tubes of the same type surrounding the collection chamber. There are two uniform distributors, located at the bottom center of two containers with the same liquid level, one in container one and the other in container two. One end of connecting pipe one within container one and the other end of connecting pipe two within container two are connected to the collection chamber of their respective uniform distributors. Beneficial effects: It enables physical connection between the liquid in the immersion container and the external liquid, maintaining the specific physicochemical properties of the liquid; it requires no manual monitoring or alarm devices, and can automatically and instantly replenish water during testing periods lasting several months.

[0018] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1 (corresponding appendix) Figure 1 —8) like Figure 1 , 3As shown in Figures 5 and 6, a high-temperature immersion test device for automotive components includes a heating container 2, an immersion container 1, and an automatic liquid replenishment system 4. The heating container 2 has an upward-facing opening and contains an electric heating component. The immersion container 1 is at least partially immersable in the heating container 2, with at least its bottom made of a thermally conductive material and its top having an upward-facing opening. In application, the immersion container 1 contains a liquid (liquid I), and the device under test is placed in the liquid I. The heating container 2 contains a liquid (liquid II) that submerges the electric heating component. The lower part of the immersion container 1 is placed in the heating container 2 and in contact with the surface 20 of the liquid II in the heating container 2. The high-temperature liquid II in the heating container 2 conducts heat to the liquid I in the immersion container 1 through the lower part of the immersion container 1. Throughout the immersion process, the electric heating component continuously supplies heat, and the automatic liquid replenishment system 4 replenishes the liquid in both the heating container 2 and the immersion container 1 in real time. In this way, the liquid I in the immersion container 1 is separated from the liquid II in the heating container 2, which can prevent the ions generated by the ionization of the liquid II in the heating container 2 during electric heating from affecting the device under test during immersion. Meanwhile, during the high-temperature evaporation and water loss process of liquid one and liquid two, water can be automatically and instantly replenished by the automatic liquid replenishment system 4. Therefore, no personnel are required to be on duty or to set up alarm devices. Under the premise of ensuring the success of the product test on the first attempt, the labor cost of long-term personnel supervision is eliminated.
[0019] like Figure 1 , 6 As shown, a rim 11 is provided around the center of the outer periphery of the soaking container 1. After the heating container 2 is placed below the soaking container 1, the rim 11 can press against the top edge of the opening of the heating container 2, so that the entire soaking container 1 can cover the opening of the heating container 2. This reduces the evaporation of the liquid 2 inside the heating container 2 and also prevents external dust from falling in. However, the soaking container 1 is not airtight after being covered. The pressure inside the covered heating container 2 is the same as the external atmospheric pressure, which is necessary for subsequent automatic liquid replenishment.
[0020] like Figure 1 , 7 Therefore, the immersion container 1 has a cap 3 for covering its opening, and the air pressure inside the immersion container 1 covered by the cap 3 is also atmospheric pressure. The central area of the cap 3 has an operating hole 31 that is open at both ends, and is equipped with various wire guide plates 32 that can cover the operating hole 31, through which electrical wires 14 can be forcefully passed. Preferably, the wire guide plates 32 are made of an elastic material such as rubber that can automatically close after being perforated. Electrical wires 14 are passed through the wire guide plates 32 because some electronic products under test need to be tested under simulated power-on conditions.
[0021] like Figure 1As shown in Figure 4, the automatic liquid replenishment system 4 includes a storage container 401, a liquid level equalization container 41, a liquid level equalization container 42, a connecting pipe 45 connecting the liquid level equalization container 41 to the immersion container 1, and a connecting pipe 46 connecting the liquid level equalization container 42 to the heating container 2. Liquid 1 and liquid 2 are the same liquid. In application, the liquid level equalization container 41 contains liquid 1, which has a liquid level equal to the height of liquid level 10, because the liquid level equalization container 41 is connected to the immersion container 1 through the connecting pipe 45. In application, the liquid level equalization container 42 contains liquid 2, which has a liquid level equal to the height of liquid level 20. The liquid level 2 422 is equal in height because the liquid level 2 container 42 is connected to the heating container 2 through the connecting pipe 2 46; the liquid level 1 container 41 and the liquid level 2 container 42 are respectively provided with overflow hole 1 413 and overflow hole 2 423, and the height of the liquid level 1 412 and the liquid level 2 422 are determined by the overflow hole 1 413 and the overflow hole 2 423 respectively; the liquid stored in the liquid storage container 401 can automatically flow into the liquid level 1 container 41 and the liquid level 2 container 42, and the upper part of the liquid level 1 container 41 and the liquid level 2 container 42 are respectively provided with atmospheric pressure vent hole 1 414 and atmospheric pressure vent hole 2 424. During application, the liquid in the storage container 401 continuously flows into the liquid level container 41. When the liquid exceeds the overflow hole 413, it will flow out from the overflow hole 413, so that the height of the liquid level 412 in the liquid level container 41 is always maintained at the set height. During the continuous evaporation of the liquid in the soaking container 1, the liquid in the actual liquid level container 41 is continuously replenished into the soaking container 1 to maintain the liquid level 412 and the liquid level 10 at the same height. That is, as long as the flow rate of the liquid flowing into the liquid level container 41 is equal to or slightly more than the evaporation in the soaking container 1, the set height of the liquid level 10 in the soaking container 1 can always be maintained. Similarly, the liquid in the storage container 401 continuously flows into the liquid level container 42. When the liquid exceeds the overflow hole 423, it will flow out from the overflow hole 423, so that the height of the liquid level 422 in the liquid level container 42 is always maintained at the set height. During the continuous evaporation of the liquid in the heating container 2, the liquid in the actual liquid level container 42 is continuously replenished into the soaking container 1 to maintain the liquid level 422 and the liquid level 20 at the same height. That is, as long as the flow rate of the liquid flowing into the liquid level container 42 is equal to or slightly more than the evaporation in the heating container 2, the set height of the liquid level 20 in the heating container 2 can always be maintained.
[0022] Overflow hole 413 is connected to liquid level container 42 via flow pipe 44. The liquid stored in storage container 401 first flows into liquid level container 41, and the liquid flowing out of overflow hole 413 of liquid level container 41 flows into liquid level container 42 via flow pipe 44, so that storage container 401 supplies water to liquid level containers 41 and liquid level container 42 in series. In this way, it is not necessary to set up separate flow channels between storage container 401 and liquid level container 41, and between storage container 401 and liquid level container 42. More importantly, only one output pipe is set from storage container 401, which facilitates high-precision control of the total flow rate.
[0023] Furthermore, a drip valve 47 is installed on the liquid level equalization container 41. The upper end of the drip valve 47 is connected to the liquid storage container 401 through the liquid supply pipe 4011, and the lower end is connected to the drip pipe 415 inserted into the liquid level equalization container 41. The drip valve 47 controls the drip supply of liquid into the liquid level equalization container 41 through the drip pipe 415. A drip pipe 425 is installed at the top of the liquid level equalization container 42 and inserted into the liquid level equalization container 42. The upper end of the drip pipe 425 is connected to the cross-flow pipe 44, and the drip pipe 425 supplies liquid into the liquid level equalization container 42.
[0024] On the one hand, since the temperatures of liquid one in soaking container 1 and liquid two in heating container 2 have not reached the boiling point, and the total evaporation surface of soaking container 1 and heating container 2 is only 0.4-0.7 square meters, the actual evaporation is very small, and the liquid supply by dripping can fully meet the liquid replenishment needs; on the other hand, dripping can precisely control the water usage and reduce the amount of pre-stored water. At the same time, since the droplets 49 are independent during the dripping process, they can completely sever the physical connection between soaking container 1 and the upper and lower water bodies, especially avoiding the formation of a water flow connection with heating container 2 and avoiding the influence of ionized ions caused by the electric heater in heating container 2.
[0025] like Figure 1 , 2As shown, the automatic liquid replenishment system 4 also includes a liquid replenishment and supply mounting frame 40. The first liquid level container 41 and the second liquid level container 42 have a first fixed base plate 411 and a second fixed base plate 421, respectively. The first liquid level container 41 and the second liquid level container 42 are fixed on the first fixed base plate 411 and the second fixed base plate 421, respectively. A permanent magnet (not shown in the figure) is provided in both the first fixed base plate 411 and the second fixed base plate 421. An iron positioning plate 48 is provided on the liquid replenishment and supply mounting frame 40. The first liquid level container 41 and the second liquid level container 42 are adsorbed onto the iron positioning plate 48 through the first fixed base plate 411 and the second fixed base plate 421, respectively. The liquid storage container 401 is installed on the liquid replenishment and supply mounting frame 40 above the iron positioning plate 48. In this way, the heights of the first liquid level container 41 and the second liquid level container 42 can be arbitrarily adjusted on the iron positioning plate 48. That is, it is equivalent to adjusting the height of the first liquid level 10 in the soaking container 1 and the second liquid level 20 in the heating container 2 by adjusting the heights of the first liquid level container 41 and the second liquid level container 42 on the iron positioning plate 48.
[0026] In this embodiment: The electric heating element is a heating wire 21; A thermometer 13 that can be observed from the outside can be installed on the cover 3; The liquid is preferably water, but oil is also acceptable; To prevent scaling and clogging, filtered purified water is preferred. The upper sidewalls of heating container 2 and immersion container 1 are insulated with heat-insulating material; A residual liquid accumulation container 402 is provided at the lower part of the liquid supply mounting bracket 40. The liquid flowing out from the overflow hole 423 flows into the accumulation container 402 through the overflow pipe 4021. Overflow hole 1 413 and overflow hole 2 423 are the upper ports of the cross-flow pipe 44 and the overflow pipe 4021, respectively. Of course, overflow hole 1 413 and overflow hole 2 423 can also be directly set on the liquid level equal container 1 41 and the liquid level equal container 2 42, respectively. The liquid level equal-height container 41 and the liquid level equal-height container 42 are preferably transparent.
[0027] The working principle of the automatic fluid replenishment system 4 will be briefly described below: Bring the soaking container 1 and heating container 2 into normal operating condition, i.e., observe the thermometer 13 for a period of time, and observe that the temperature of the liquid 2 in the soaking container 1 is stable within the set value range; open the drip valve 47, so that the drip tube 1 415 drips liquid into the liquid level container 41, so that the height of the liquid level 1 412 is maintained at the position of the overflow hole 1 413, and excess liquid drips from the overflow hole 1 413 into the liquid level container 42 through the cross-flow tube 44 and the drip tube 2 425, so that the height of the liquid level 2 422 is maintained at the position of the overflow hole 2 423, and excess liquid flows out from the overflow hole 2 423; observe for a period of time (which may be several hours or several days) to confirm that there is always liquid flowing out of the overflow hole 2 423. Example 2
[0028] like Figure 9 , 10 As shown, it is a further improvement of the first embodiment. The bottom of the soaking container 1 is provided with a heat-conducting plate 12 that evenly transfers heat into the soaking container 1. The heat-conducting plate 12 has a set thickness. Only the heat-conducting plate 12 is immersed in the liquid 2 in the soaking container 1. In this way, heat can be conducted to the soaking container 1 more evenly through the heat-conducting plate 12, ensuring that the temperature of the liquid 1 in the soaking container 1 is basically the same everywhere. Example 3
[0029] like Figure 11 , 12 As shown, this is a further improvement of the above embodiment. The automatic liquid replenishment system 4 also includes a uniform distributor 43. The uniform distributor 43 includes a liquid collection chamber 431 and multiple distribution pipes 432, identical to the liquid collection chamber 431, arranged radially at equal intervals around the outer periphery of the liquid collection chamber 431. Each distribution pipe 432 has an equal length. There are two uniform distributors 43, which are respectively located at the bottom center of the soaking container 1 and the heating container 2. One end of the connecting pipe 45 located in the soaking container 1 and the other end of the connecting pipe 46 located in the heating container 2 are respectively connected to the liquid collection chamber 431 of their respective uniform distributors 43. In application, the liquid flowing into the liquid collection chamber 431 can be distributed relatively evenly to multiple points in the container through the multiple distribution pipes 432 to ensure that the temperature of liquid 1 in the soaking container 1 is basically equal and the temperature of liquid 2 in the heating container 2 is basically equal.
[0030] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
