Referring to fig. 2, fig. 2 is a block diagram of a thermal shock testing apparatus according to the present utility model. The apparatus may include:
a first medium conduit 100, a first valve 120 and a medium heating device 130.
Wherein the first medium conduit 100 comprises a medium inlet 101 and a medium outlet 102.
Wherein the medium inlet 101 is connected to a medium input device for guiding a medium into the first medium conduit 100.
Wherein the medium outlet 102 is connected to the heat load under test 110, and transmits the medium guided into the first medium pipe 100 into the heat load under test 110.
Wherein the first valve 120 is located on the first medium conduit 100 between the medium inlet 101 and the medium outlet 102. When the first valve 120 is opened, the medium may be conducted to the heat load under test 110 through the first medium pipe 100, heating the heat load under test 110; when the first valve 120 is turned off, the medium cannot be transferred to the measured heat load element 110, and the temperature of the measured heat load element 110 is not affected by the medium.
The medium heating device 130 is located between the medium inlet 101 and the medium outlet 102, so as to heat the medium, thereby increasing the temperature of the medium, and further conducting heat to the heat load element 110 to be tested through the first medium pipe 100, so as to heat the heat load element 110 to be tested.
The medium may be air or water, or other gas or liquid heat transfer medium for heat conduction, which is not limited in the present utility model.
The measured thermal load element is an exhaust gas recirculation (Exhaust Gas Recirculation, abbreviated as EGR) cooler or a steel sleeve, and of course, the measured thermal load element can also be other elements or devices which need to be subjected to thermal shock test, and the utility model is not limited to the above. When the thermal shock test is performed on the thermal load member 110 to be tested, the coolant in the coolant conveying pipe of the thermal load member 110 to be tested is operated to cool the thermal load member 110 to be tested.
In performing the thermal shock test, the medium heating device 130 is operated to heat the medium through the first medium pipe 100. When the first valve 120 is opened, the medium inlet 101 of the thermal shock test device receives the medium from the medium input device, the medium is heated in the first medium pipeline 100 by the medium heating device 130, and is conveyed to the heat load member 110 to be tested through the first medium pipeline 100 so as to heat the heat load member 110 to be tested, and the medium flowing through the medium conveying pipeline of the heat load member 110 to be tested is discharged through the outlet of the medium conveying pipeline, so that the medium can be recovered by the medium recovery device; when the first valve 120 is closed, the first medium pipe 100 is turned off, the medium is not conveyed to the heat load member 110 to be measured, the heat load member 110 to be measured stops heating, and at this time, the heat load member 110 to be measured cools itself through the circulation of the cooling liquid in the cooling liquid conveying pipe. The measured thermal load member 110 is in a state of alternately striking cold and hot by the opening and closing of the first valve 120, so as to complete the thermal shock test.
The thermal shock test device provided by the utility model only adopts a single medium pipeline to input the heating medium into the tested thermal load piece so as to heat the tested thermal load piece, the tested thermal load piece is cooled through the circulation of the cooling liquid in the cooling liquid conveying pipeline of the tested thermal load piece, and whether the tested thermal load piece is heated or not is controlled by opening and closing the valve, so that cold and hot alternate impact is realized to complete the thermal shock test. Compared with the design thought that two cold and hot pipelines are adopted to cool and heat the tested heat load piece in the related art, the thermal shock test device provided by the utility model greatly reduces the complexity of the test device and the difficulty of device construction, reduces the resource consumption of device construction, and reduces the maintenance cost of the subsequent test device.
In order to improve the efficiency of the thermal shock test, according to the thermal shock test device, the first medium pipeline is further provided with two or more medium outlets and medium outlet branches, the medium outlet branches are in one-to-one correspondence with the medium outlets, and the two or more medium outlets are in one-to-one correspondence with the inlets of the medium conveying pipelines of the same number of the thermal load pieces to be tested.
Referring to fig. 3, fig. 3 is a thermal shock test apparatus provided by the present utility model. The apparatus may include:
a first media line 200, a first valve 220, and a media heating device 230.
In comparison with the test apparatus shown in fig. 2, the first medium conduit 200 in the test apparatus provided in fig. 3 includes a medium inlet 201 and two medium outlets 202 and 203, and the medium outlets 202 and 203 are connected to the thermal load members 211 and 212, respectively, to be tested.
By branching the first medium pipe 200 to obtain a plurality of medium outlets and a plurality of medium outlet branches, a plurality of thermal load pieces to be tested can be tested at the same time, thereby improving the efficiency of thermal shock test.
Of course, in the present embodiment, the thermal shock test is performed on two thermal load devices to be tested at the same time, and in the thermal shock test device, the medium outlet may be divided into more medium outlets, and the thermal shock test is performed on more thermal load devices to be tested at the same time, which is not limited in the present utility model.
In order to accelerate the working condition conversion speed and further improve the thermal shock test efficiency, according to the thermal shock test device, further, the first valve is located between the medium heating device and the medium inlet.
With continued reference to fig. 3, in fig. 3 the first valve 220 is positioned before the media heating device 230, i.e. the first valve 220 is positioned closer to the media input device than the media heating device 230, and is also used to control the opening and closing of the media outlets 202 and 203 to the thermal load under test 210 and 211.
The medium heating device 230 is located at the rear end of the first valve 220, and is used for controlling the opening and closing of the medium outlet, so that the first valve 220 can avoid the medium heated by the medium heating device 230, and thus can work in a colder medium environment. Because the valve can be opened and closed fast when working in a low-temperature environment, the valve reliability of the opened and closed fast can not be reduced fast due to a high-temperature environment, and the opening and closing speed of the valve can reach tens of milliseconds at the moment, so that the working condition transition time is shortened greatly on the premise of ensuring the valve reliability, and the thermal shock test efficiency is improved.
When the thermal shock test is carried out on the measured thermal load piece, the medium heating device is positioned on the main path of the first medium pipeline. The main way is a first medium pipeline which is used for conveying the medium for each medium outlet branch and the measured heat load piece before being divided into the medium outlet branches. And heating the medium in the main path through a medium heating device to provide heat for thermal shock tests of all the tested thermal load pieces.
Of course, when the thermal shock test device performs the thermal shock test on the thermal load piece to be tested, there may be more medium outlet branches than the thermal load piece to be tested, in this case, the medium heating device may be moved to the branch needing the thermal shock test, and the medium passing through other branches is directly recovered by the medium recovery device without heating, thereby further saving energy in the thermal shock test.
According to the thermal shock test device, the device further comprises a second valve, wherein the second valve is arranged on the medium outlet branch and used for controlling the on-off of the medium outlet branch.
Referring to fig. 4, fig. 4 is a thermal shock test apparatus provided by the present utility model. The apparatus may include:
a first medium pipe 300, a first valve 320 and a medium heating device 330; the first medium conduit 300 comprises a medium inlet 301 and two medium outlets 302 and 303, and two medium outlet branches corresponding to the two medium outlets, respectively.
Compared with the thermal shock test device shown in fig. 3, in the thermal shock test device provided in fig. 4, a second valve 321 and a second valve 322 are added on each medium outlet branch, and the two valves respectively control the on-off of the medium outlets leading to the two thermal load pieces 311 and 310 to be tested.
In some implementations of the present embodiment, the measured thermal load pieces 310 and 311 have the same specification and the same test standard, and at this time, the second valve 321 and the second valve 322 may be opened and closed synchronously, so as to perform synchronous test on the measured thermal load pieces 311 and 310, thereby improving the accuracy of the test.
In other implementations of this embodiment, the measured thermal load pieces 310 and 311 are different in specification and different in test standard, and at this time, the second valve 321 and the second valve 322 may be controlled separately, so as to control the opening and closing of the valves according to the respective test targets of the measured thermal load pieces 311 and 310, so as to perform the test process on different kinds of measured thermal load pieces by using the same set of thermal shock test devices.
In other implementations of the present embodiment, the output power of the media heating device 330 is insufficient to heat a sufficient amount of the input media to a temperature that supports simultaneous testing of the thermal load under test 311 and 310. At this time, the second valve 321 and the second valve 322 may be controlled in combination to be alternately opened and closed: namely, the second valve 321 is opened to heat the measured heat load piece 311, and at the moment, the second valve 322 is closed to cool the measured heat load piece 310 by using the cooling liquid circulation in the cooling liquid conveying pipeline of the measured heat load piece; when the second valve 322 is opened, the second valve 321 is closed to heat the measured heat load piece 310, and the measured heat load piece 311 is cooled by using the cooling liquid circulation in the cooling liquid conveying pipeline of the measured heat load piece; thus realizing simultaneous testing of a plurality of tested heat load pieces on the occasion of consuming less energy.
In order to accelerate the working condition conversion speed and improve the thermal shock test efficiency, according to the thermal shock test device, further, the device further comprises a second medium pipeline and a third valve: the second medium pipeline is connected with an outlet of the medium conveying pipeline of the measured thermal load piece; the third valve is arranged on the second medium pipeline and used for controlling the on-off of the second medium pipeline.
Referring to fig. 5, fig. 5 is a thermal shock test apparatus provided by the present utility model. The apparatus may include:
a first medium conduit 400, a first valve 420 and a medium heating device 430; the first medium conduit 400 comprises a medium inlet 401 and two medium outlets 402 and 403, and two medium outlet branches corresponding to the two medium outlets, respectively.
Compared with the test apparatus shown in fig. 4, in the test apparatus provided in fig. 5, the second medium pipes 404 and 405 are added at the medium delivery pipe outlets of the heat load pieces 411 and 410, and the original second valve 321 and second valve 322 are moved to the rear ends of the heat load pieces 411 and 410 as the third valves 421 and 422, which are also used to control the opening and closing of the medium outlets leading to the two heat load pieces.
The third valves 421 and 422 are located at the rear end of the measured heat load member instead of the second valves 321 and 322, so that the third valves 421 and 422 are far away from the medium heating device 430, thereby being capable of operating in a colder medium environment. Because the valve can be opened and closed fast when working in a low-temperature environment, the valve which is opened and closed fast can not be damaged due to the high-temperature environment, and the opening and closing speed of the valve can reach tens of milliseconds each time at the moment, so that the working condition overlength time is greatly shortened, and the thermal shock test efficiency is improved.
In order to test the medium flow, ensure the medium quantity flowing to the tested heat load part, according to the thermal shock test device, the device further comprises a medium flow sensor and a medium flow control device: the medium flow sensor is arranged on the first medium pipeline and positioned between the medium inlet and the medium outlet and is used for sending the detected medium flow value of the first medium channel to the medium flow control device; the medium flow control device is used for adjusting the opening degree of the first valve according to the received medium flow value.
In some implementations of this embodiment, the thermal shock test apparatus tests n thermal load pieces under test simultaneously, where n is an integer greater than or equal to 2. The medium flow in the first medium pipeline is enough to meet the test requirements of n tested heat load pieces according to the test of the medium flow sensor on the main circuit of the first medium pipeline. At the moment, the thermal shock test device can be integrally controlled through the first valve, medium energy is efficiently utilized, the thermal shock test effect is ensured, meanwhile, the valve control complexity is reduced, and the thermal shock test efficiency is improved.
In other implementations of this embodiment, the thermal shock test apparatus also tests n thermal load cells under test simultaneously. However, the medium flow rate in the first medium pipeline is insufficient to meet the test requirements of all the tested heat load pieces through the medium flow rate sensor test on the main pipeline of the first medium pipeline. The medium flow control device can calculate the quantity of the thermal shock tests of the tested thermal load parts which can be met by the medium flow according to the medium flow value detected by the medium flow sensor through a preset algorithm, then the valves on each medium branch are controlled to be alternately opened and closed, namely, only the valves which can meet the quantity of the thermal shock tests of the tested thermal load parts are simultaneously reserved to be opened, other valves are closed, after the medium flow control device heats for a certain time, the opened valves are closed, and other valves with the same quantity are selected to be opened, so that the thermal shock tests of all the tested thermal load parts can be completed through iterative circulation.
In other implementations of the present embodiment, in order to achieve precise control, in this embodiment, a medium flow sensor and a medium flow control device may be disposed on the medium outlet branch as well, so that the opening of the valve corresponding to the medium outlet branch is controlled according to the same control concept as that of the above implementation, so as to achieve precise control of thermal shock of each measured thermal load member.
In order to control the output power of the medium heating device, reduce the energy consumption, control the heating temperature of the measured thermal load piece at the same time, according to the above thermal shock test device, further, the device also comprises a medium temperature sensor and a medium temperature control device: the medium temperature sensor is arranged on the first medium pipeline, is positioned between the medium heating device and the medium outlet and is used for sending the detected medium temperature value of the first medium channel to the medium temperature control device; the medium temperature control device is used for adjusting the output power of the medium heating device according to the received medium temperature value.
The medium temperature value detected by the medium temperature sensor is used, the medium temperature control device controls the output power of the medium heating device according to the medium temperature value, so that the medium temperature is stabilized within a certain temperature range and meets the thermal shock test requirement, unnecessary energy consumption is reduced as much as possible on the premise of meeting the test requirement, and meanwhile, the heating temperature of the tested thermal load piece is controlled.
