[0053] When performing aging tests on hardware products, it is necessary to first place multiple products in the test chamber of the test equipment, then increase the temperature of the test chamber to perform high-temperature aging on multiple products, and finally test the aged products to evaluate their performance and lifespan in extreme temperature environments in order to determine the performance of the products.

[0054] In the current related technologies, the test equipment performs heat exchange between the test cavity and the heating cavity through the air inlet and the air outlet. However, the air inlet and the air outlet are usually located on the same side of the test cavity. When there are multiple products to be tested in the test cavity, the temperatures of the various areas where the multiple products to be tested are located in the test cavity are different, resulting in different aging degrees of the multiple products to be tested, and inaccurate judgment of the performance of the products to be tested.

[0055] In view of this, it is necessary to provide a test device with a test cavity with uniform temperature. The test device includes a shell and a circulation component; the shell has a first cavity and a second cavity, the first cavity is used to accommodate the product to be tested, the cavity wall of the first cavity is provided with an air inlet and an air outlet arranged oppositely, and the second cavity is connected to the first cavity through the air inlet and the air outlet; the circulation component is arranged in the shell and located in the second cavity, the circulation component includes a heating element, an air inlet element and an air outlet element, the air inlet element is arranged at the air inlet, the air outlet element is arranged at the air outlet, the heating element is used to heat the gas in the second cavity, the air inlet element is used to make the gas passing through the heating element enter the first cavity through the air inlet, the air outlet element is used to make the gas in the first cavity enter the second cavity through the air outlet, the air inlet element and the air outlet element form an airflow from the air inlet to the air outlet in the first cavity, and the airflow passes through each product to be tested.

[0056] The above-mentioned testing equipment forms a first cavity and a second cavity through a shell, and the gas in the second cavity can be heated and heated by a heating element. By arranging an air inlet and an air outlet connecting the first cavity and the second cavity on the cavity wall of the first cavity, heat exchange between the first cavity and the second cavity is facilitated; by arranging an air inlet piece connected to the air inlet and an air outlet piece connected to the air outlet, the gas can circulate rapidly between the second cavity and the first cavity through the air inlet and the air outlet, and form an airflow that continuously blows from the air inlet to the air outlet, and the air inlet and the air outlet are arranged relative to each other so that the airflow can be blown out from the air inlet in a straight line toward the air outlet and pass through each product to be tested, so that the temperatures of various areas of the first cavity where the products to be tested are arranged can change at the same time, and the temperature in the first cavity is uniform, so that multiple products to be tested arranged in the first cavity can be aged to the same degree. Therefore, the first cavity of the above-mentioned testing equipment is used as a testing cavity, and the temperature of each area in the first cavity is uniform, so that the aging degree of multiple products to be tested in the first cavity is basically the same, making the test results of multiple products to be tested more accurate, and can improve the accuracy of product performance judgment.

[0057] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] See also Figure 1 and Figure 2 In one embodiment of the present application, a testing device 100 is provided for performing an aging test on an electronic device to evaluate the performance of the electronic device.

[0059] In some embodiments, the test device 100 includes a housing 10 and a circulation assembly 30. The housing 10 is used to install the circulation assembly 30. The housing 10 is also used to form a first cavity 11 and a second cavity 12. The first cavity 11 is used to accommodate the product 200 to be tested. The wall of the first cavity 11 is provided with an air inlet 111 and an air outlet 112 connected to the second cavity 12. The circulation assembly 30 is arranged in the housing 10. The circulation assembly 30 is used to make the gas flow between the first cavity 11 and the second cavity 12, and to generate an airflow that blows straightly from the air inlet 111 to the air outlet 112. The airflow passes through each product 200 to be tested, so that the temperature of each area of ​​the first cavity 11 containing the product 200 to be tested changes at the same time, the temperature in the first cavity 11 is uniform, and the temperature of the multiple products 200 to be tested contained in the first cavity 11 is substantially the same.

[0060] In some embodiments, the electronic device is contained in the first cavity 11. When the first cavity 11 and the second cavity 12 perform heat exchange, the temperature of the first cavity 11 changes, and the electronic device is in different ambient temperatures. By detecting the performance of the electronic device under different ambient temperature conditions, the product quality of the electronic device can be determined. As an illustrative example, the electronic device is a hard disk.

[0061] In some embodiments, the air inlet 111 and the air outlet 112 are both disposed on the cavity wall of the first cavity 11, so that the second cavity 12 is connected to the first cavity 11 through the air inlet 111 and the air outlet 112. The air inlet 111 and the air outlet 112 are disposed opposite to each other so that the air flow can be blown out from the air inlet 111 in a straight line toward the air outlet 112, so that the air flow can flow between the air inlet 111 and the air outlet 112 continuously and quickly.

[0062] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The circulation component 30 includes a heating element 31, an air inlet element 32, and an air outlet element 33. The heating element 31 is located in the second cavity 12, and the heating element 31 is used to heat the gas in the second cavity 12, so that the temperature of the gas in the second cavity 12 is different from that of the gas in the first cavity 11, and a temperature difference is generated between the first cavity 11 and the second cavity 12. The air inlet member 32 is located in the second cavity 12, and is disposed at the air inlet 111. The air inlet member 32 is used to allow the gas passing through the heating member 31 to enter the first cavity 11 through the air inlet 111; the air outlet member 33 is located in the second cavity 12, and is disposed at the air outlet 112. The air outlet member 33 is used to allow the gas in the first cavity 11 to enter the second cavity 12 through the air outlet 112; the gas in the first cavity 11 and the second cavity 12 is exchanged by the air outlet member 33 and the air inlet member 32, so that heat exchange occurs between the first cavity 11 and the second cavity 12, thereby causing the temperature in the first cavity 11 to change continuously.

[0063] Therefore, when the above-mentioned testing equipment 100 performs heat exchange on the first cavity 11 in the second cavity 12, the temperature of each area of ​​the first cavity 11 where the product to be tested 200 is provided can change evenly, and the aging degree of the products to be tested 200 is the same. When testing the performance of multiple products to be tested 200, the test results obtained are more accurate, thereby improving the accuracy of product performance judgment.

[0064] In some embodiments, the testing device 100 further includes a testing piece 20 , which is connected to the housing 10 . The testing piece 20 is used to electrically connect to the product to be tested 200 and detect the performance of the electrically connected product to be tested 200 .

[0065] In some embodiments, the test piece 20 may be one, and multiple products to be tested 200 are connected to the test piece 20 . The airflow can pass through each product to be tested 200 connected to the test piece 20 to detect the performance of the multiple products to be tested 200 .

[0066] In some embodiments, there can be multiple test pieces 20, which are arranged in the housing 10 along the direction from the air inlet 111 to the air outlet 112, so that the airflow can pass through each product 200 to be tested, so that the aging degree of each product 200 to be tested is basically the same.

[0067] In some embodiments, the second cavity 12 surrounds the first cavity 11. It is understandable that heat exchange will occur if there is a temperature difference between two objects in contact with each other. There is a temperature difference between the second cavity 12 and the first cavity 11, so heat exchange may occur between the second cavity 12 and the first cavity 11 through the cavity wall of the first cavity 11. The periphery of the first cavity 11 is surrounded by the second cavity 12, so that the temperature of the periphery of the first cavity 11 is uniform, which is conducive to the second cavity 12 transferring heat to the periphery of the first cavity 11, and is conducive to the uniform temperature of various areas in the first cavity 11.

[0068] In some embodiments, the housing 10 further includes a heat preservation layer 14, which is disposed on the outer periphery of the second cavity 12. The heat preservation layer 14 can increase the heat preservation effect of the second cavity 12, and can make the second cavity 12 reach the required temperature more quickly, thereby making the first cavity 11 reach the required temperature.

[0069] In some embodiments, see Figure 2 The second cavity 12 includes an upper channel 121, a lower channel 122 and two side channels 123. The upper channel 121 and the lower channel 122 are parallel and are respectively arranged on the upper and lower sides of the first cavity 11. Each side channel 123 connects the two ends of the same side of the upper channel 121 and the lower channel 122, so that the two side channels 123 connect the upper channel 121 and the lower channel 122, so that the second cavity 12 surrounds the first cavity 11.

[0070] In some embodiments, the first cavity 11 is rectangular, so that multiple test pieces 20 can be evenly arranged from bottom to top, and multiple products to be tested 200 are electrically connected to one end of the test piece 20 facing the first cavity 11, so that the multiple products to be tested 200 are evenly distributed, which facilitates airflow through each product to be tested 200; the air inlet 111 and the air outlet 112 are arranged on the outer cavity wall of the first cavity 11, and the inner cavity wall of the second cavity 12 coincides with the outer cavity wall of the first cavity 11. The second cavity 12 is in a rectangular ring shape surrounding the outer periphery of the first cavity 11, which is conducive to making the temperature of each area in the first cavity 11 uniform.

[0071] In some embodiments, see Figure 5 , the air inlet 111 is arranged in the lower channel 122, and the air outlet 112 is arranged in the upper channel 121. A heating element 31 is arranged in each of the two side channels 123. The gas entering the upper channel 121 through the air outlet 112 enters the side channels 123 respectively, and the heating element 31 heats the gas in the two side channels 123 and then enters the lower channel 122. The gas in the lower channel 122 that passes through the heating element 31 enters the first cavity 11 through the air inlet 111. By arranging the heating element 31 in both side channels 123, the temperature of the gas entering the lower channel 122 is uniform, and the temperature of the gas entering the first cavity 11 is uniform, which is conducive to the uniform temperature of each area in the first cavity 11. In addition, the temperature of the gas after passing through the heating element 31 is relatively high, and the gas with a higher temperature has the characteristic of moving upward. Therefore, the high-temperature gas blowing from bottom to top is conducive to the formation of airflow.

[0072] In some embodiments, see Figure 1 and Figure 4 The air inlet 32 ​​includes a plurality of first fans 321 spaced apart in the lower channel 122. The plurality of first fans 321 are evenly spaced apart and installed on the common lower cavity wall of the first cavity 11 and the second cavity 12. There are four first fans 321. The air inlet 111 forms four evenly spaced circular holes. Each air inlet 111 is installed with a first fan 321. The first fan 321 blows the gas in the lower channel 122 upward. Figure 1 The figure shows that three circular holes are installed with the first fan 321, and one circular hole is not installed with the first fan 321. Figure 2 and Figure 4 The air outlet 33 includes a plurality of second fans 331 spaced apart in the upper channel 121. The plurality of second fans 331 are evenly spaced apart and installed on the common upper cavity wall of the first cavity 11 and the second cavity 12. There are four second fans 331. The air outlet 112 forms four evenly spaced circular holes. Each air outlet 112 is installed with a second fan 331. The second fan 331 blows the gas in the first cavity 11 into the upper channel 121. Figure 2The figure shows a situation where three circular holes are installed with the second fans 331 and one circular hole is not installed with the second fan 331. The number of the second fans 331 is the same as that of the first fans 321 and they correspond to each other, so that the gas blown out by the first fan 321 is blown toward the second fan 331, and the second fan 331 can receive the gas blown out by the first fan 321, so as to form an airflow blowing straightly upward from the bottom, so as to facilitate the rapid circulation of the gas between the first cavity 11 and the second cavity 12.

[0073] In some embodiments, the first fan 321 is an exhaust fan, and the second fan 331 is an intake fan.

[0074] In some embodiments, see Figure 3 The cavity wall of the second cavity 12 is provided with a first ventilation port 1231 and a second ventilation port 1232, and the first ventilation port 1231 and the second ventilation port 1232 are both provided with valves, and the valves are used to open or close the first ventilation port 1231 and the second ventilation port 1232. By opening the valves, the gas in the second cavity 12 and the external gas can be exchanged through the first ventilation port 1231 and the second ventilation port 1232. The first ventilation port 1231 and the second ventilation port 1232 are used to exchange the gas between the second cavity 12 and the outside, so that the second cavity 12 and the outside can exchange heat to balance or reduce the temperature in the second cavity 12 and the first cavity 11.

[0075] In some embodiments, the valve is a damper.

[0076] In some embodiments, see Figure 5 The circulation component 30 further includes a first ventilation member 34 and a second ventilation member 35 disposed in the housing 10 and located in the second cavity 12. The first ventilation member 34 is disposed at the first ventilation port 1231, so that the gas in the second cavity 12 is discharged through the first ventilation port 1231. The second ventilation member 35 is disposed at the second ventilation port 1232, so that the external gas enters the second cavity 12 through the second ventilation port 1232. The first ventilation member 34 and the second ventilation member 35 accelerate the exchange between the external gas and the gas in the second cavity 12, so that the second cavity 12 exchanges heat with the outside, so as to appropriately adjust the temperature in the second cavity 12. By adjusting the temperature of the second cavity 12, the temperature of the first cavity 11 can be adjusted.

[0077] In some embodiments, the first ventilation element 34 is an exhaust fan, and the second ventilation element 35 is an intake fan.

[0078] In some embodiments, see Figure 3 and Figure 5, the first ventilation port 1231 is arranged above the second ventilation port 1232. Since the temperature of the gas in the second cavity 12 is higher than that of the external gas, the gas with a higher temperature has the characteristic of going upwards, so by arranging the first ventilation port 1231 above the second ventilation port 1232, the gas with a higher temperature in the second cavity 12 can be discharged more quickly, and the gas entering the second cavity 12 from the second ventilation port 1232 is prevented from being discharged directly from the first ventilation port 1231, which can accelerate the gas exchange between the second cavity 12 and the outside.

[0079] In some embodiments, see Figure 5 The first ventilation port 1231 is disposed above the air outlet 112. The gas blown from the air outlet 112 toward the upper channel 121 can pass through the first ventilation port 1231 to the outside more quickly, so that the gas entering the second cavity 12 from the second ventilation port 1232 can enter the first cavity 11 more quickly through the inlet wind, which can accelerate the heat exchange between the first cavity 11 and the second cavity 12, and facilitate the rapid adjustment of the temperature in the first cavity 11 and the second cavity 12 through the first ventilation port 1231 and the second ventilation port 1232.

[0080] In some embodiments, there are two second ventilation ports 1232, and the two second ventilation ports 1232 are respectively arranged on both sides of the air outlet 112. External air enters the second cavity 12 through the two second ventilation ports 1232, and specifically enters the second cavity 12 from the top of the two side channels 123, and then circulates in the second cavity 12, and also continuously exchanges heat with the first cavity 11, which facilitates gas exchange between the outside and the second cavity 12, and facilitates rapid adjustment of the temperature of the second cavity 12 and the first cavity 11.

[0081] In some embodiments, see Figure 4 The test device 100 further includes a sensing member 40, which is disposed on the housing 10 and located in the first cavity 11, so as to sense the temperature of the first cavity 11. The sensing member 40 includes a first sensor 41 and a second sensor 42, and the first sensor 41 is disposed at the air inlet 111 to sense the temperature of the gas blown into the first cavity 11 through the air inlet 111 from the second cavity 12. The second sensor 42 is disposed at the air outlet 112 to sense the temperature of the gas blown into the second cavity 12 from the first cavity 11 through the air outlet 112. By sensing the temperature of the gas entering and exiting the first cavity 11 through the first sensor 41 and the second sensor 42, the temperature of the first cavity 11 can be better monitored, the heat exchange between the first cavity 11 and the second cavity 12 can be balanced, and the temperature of each area in the first cavity 11 can be uniform.

[0082] In some embodiments, the first sensor 41 and the second sensor 42 are both temperature sensors.

[0083] In some embodiments, see Figure 1 The first cavity 11 penetrates the housing 10 to form an opening, and the opening allows the product 200 to enter the first cavity 11; the housing 10 is rotatably connected to a door 13, and the door 13 is used to close the opening to close the first cavity 11. By rotating and opening the door 13, the opening can be exposed, so that the user can operate the product 200 to be tested in the first cavity 11 through the opening; by rotating and closing the door 13, the first cavity 11 can be closed, so that the first cavity 11 and the second cavity 12 can exchange heat.

[0084] In some embodiments, see Figure 4 The housing 10 includes a hollow frame 15, and the frame 15 is arranged opposite to the opening. The opening is located at the front side, and the frame 15 is located at the rear side. The test piece 20 is connected to the frame 15, and the test piece 20 is used to electrically connect to the side of the interface of the product to be tested 200, and the frame 15 does not cover the interface, so that the product to be tested 200 can be plugged into the interface through the opening or unplugged from the interface.

[0085] The aging of the product under test 200 using the above-mentioned testing equipment 100 is divided into three stages: the heating stage of the first cavity 11: open the box door 13, insert the product under test 200 into the interface of the test piece, so that the product under test 200 is located in the first cavity 11 and the product under test 200 is electrically connected to the test piece, and close the box door 13 to seal the first cavity 11. The heating element 31, the air inlet element 32 and the air outlet element 33 are operated. The air outlet element 33 allows the gas in the first cavity 11 to enter the second cavity 12 through the air outlet 112. The heating element 31 heats the gas in the second cavity 12. The air inlet element 32 allows the gas heated by the heating element 31 to enter the first cavity 11 through the air inlet 111. The gas circulates between the first cavity 11 and the second cavity 12, generating an airflow that blows straight from the air inlet 111 to the air outlet 112. The airflow passes through each product 200 to be tested, takes away the temperature of the product 200 to be tested and the first cavity 11, and evenly increases the temperature in the first cavity 11. This cycle is repeated until the temperature in the first cavity 11 is heated to the desired set value.

[0086] The balance stage of the first cavity 11: when the temperature reaches a certain required set value, the product 200 to be tested starts the aging work, and the operation of the hard disk will generate heat. In order to prevent the temperature in the first cavity 11 from continuing to rise and to make the temperature in the first cavity 11 reach a dynamic balance, the valves of the first ventilation port 1231 and the second ventilation port 1232 are opened, and the first ventilation member 34 discharges the gas with a higher temperature in the upper channel 121 through the first ventilation port 1231, and the second ventilation member 35 sucks the external gas into the second cavity 12 through the second ventilation port 1232, so that the gas temperature in the second cavity 12 is reduced, and the second cavity 12 and the first cavity 11 continuously exchange heat, so that the external gas enters to reduce the temperature to balance the heat generated by the operation of the hard disk, so that the temperature in the first cavity 11 reaches a dynamic balance.

[0087] Cooling stage of the first cavity 11: when the aging of the product 200 to be tested is completed, it is necessary to quickly lower the temperature in the first cavity 11, and the valves of the first ventilation port 1231 and the second ventilation port 1232 may be opened, and the first ventilation component 34 discharges the gas with a higher temperature in the upper channel 121 through the first ventilation port 1231, and the second ventilation component 35 draws external gas into the second cavity 12 through the second ventilation port 1232, so that the temperature of the gas in the second cavity 12 is lowered, and the second cavity 12 and the first cavity 11 continuously exchange heat, thereby lowering the temperature of the first cavity 11 and the second cavity 12, and this cycle is repeated until the temperature in the first cavity 11 is lowered to the required set value, and the performance of the product 200 to be tested after aging can be detected.

As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
