Among them, the small-scale number can be 1-32.

[0051] The test device 100 heats the cover 1 and the test platform 2. The heating cover 1 is movably mounted on the test platform 2.

In other embodiments, a blade structure may be provided in the air inlet 131, and the air intake of the heating cover body 1 can be adjusted by adjusting the setting angle of the blade in the air inlet 131.

[0055] The main body 10 further includes a plurality of partitions 14. The partitions 14 are vertically arranged on the inner surface of the top plate 11. Every four partitions 14 are connected end to end to form a heating cavity 101. Each heating cavity 101 contains at least one heating structure 20 (such as Figure 4 In at least one embodiment of the present application, the main body 10 includes four heating chambers 101. Each heating chamber 101 contains two heating structures 20 and a fan 30. In other embodiments, each heating chamber 101 may contain a heating structure 20 and a fan 30.

[0056] At least one partition 15 is further provided in the heating chamber 101. The partition 15 is used to separate the heating chamber 101 into at least one first channel 1012 and at least one second channel 1014 that are interconnected. In at least one embodiment of the present application, each heating chamber 101 has two partitions 15. The two partitions 15 are coplanar and located in a plane parallel to the top plate 11. The two partitions 15 are spaced apart. The partition 15 is roughly flat and is arranged parallel to the top plate 11. The first channel 1012 is located between the top plate 11 and the partition 15, and the second channel 1014 is located between the partition 15 and the storage device 200. In at least one embodiment of the present application, the width and shape of the first channel 1012 and the second channel 1014 can be adjusted by adjusting the position and shape of the partition 15.

[0057] The heating structure 20 is used to heat the air in the heating cavity 101 so that the ambient temperature of the storage device 200 accommodated in the heating cavity 101 rises to a target temperature range. In at least one embodiment of the present application, the target temperature range is 40 degrees to 85 degrees. In at least one embodiment of the present application, each heating structure 20 corresponds to a barrier 15. The heating structure 20 is accommodated in the first channel 1012 of the heating cavity 101 and is located above the corresponding barrier 15. In other embodiments, the heating structure 20 can also be arranged in the second channel 1014 of the heating cavity 101 according to requirements and is located below the barrier 15, and the relative position of the heating structure 20 and the barrier 15 can also be adjusted according to requirements. The heating structure 20 includes a heating portion 21 and a plurality of conducting portions 23. In at least one embodiment of the present application, the heating portion 21 is parallel to the barrier 15 and is located in the middle of the barrier 15. The plurality of conducting portions 23 are parallel to each other and vertically fixed on the surface of the heating portion 21 opposite to the top plate 11. In at least one embodiment of the present application, the heating power of the heating unit 21 can be adjusted according to demand.

[0058] The fan 30 is used to drive the air to circulate in the heating cavity 101, and is further used to introduce the cold air outside the heating cover 1 into the heating cavity 101. Specifically, driven by the fan 30, the air heated by the heating structure 20 moves from the top of the storage device 200 toward the storage device 200, and returns to the top of the storage device 200. In at least one embodiment of the present application, driven by the fan 30, the air heated by the heating structure 20 enters the second channel 1014 through the fan 30 from the first channel 1012 to reach the surrounding of the storage device 200; and then further returns to the first channel 1012 from the second channel 1014. The fan 30 is accommodated in the heating cavity 101 and is arranged near the top plate 11. In at least one embodiment of the present application, the fan 30 is located in the middle of the heating cavity 101 and is arranged between two baffles 15. The fan 30 is an axial flow fan. The speed of the fan 30 can be adjusted according to demand. In at least one embodiment of the present application, when the storage device 200 accommodated in the heating cavity 101 needs to be heated up, the speed of the fan 30 can be set to a first predetermined speed; when the storage device 200 accommodated in the heating cavity 101 needs to be cooled down, the speed of the fan 30 can be set to a second predetermined speed. The first predetermined speed and the second predetermined speed can be the same or different. In at least one embodiment of the present application, the first predetermined speed is less than or equal to the second predetermined speed. In addition, when the storage device 200 accommodated in the heating cavity 101 needs to be heated up or cooled down, the speed of the fan 30 can also be switched between a plurality of different speeds.

[0059] The sealing structure 40 is covered and arranged on one end of the main body 10 away from the top plate 11, and is used to cooperate with the top plate 11, the side plate 12 and the partition plate 14 to form a sealed space to seal the structure outside the heating cavity 101. The sealing structure 40 is used to keep the ambient temperature in the heating cavity 101 stable and avoid heat exchange between the air in the heating cavity 101 and the air in other spaces. At least one through hole 401 is provided on the sealing structure 40. The through hole 401 is connected to the heating cavity 101, and is used to allow the storage device 200 to be accommodated in the heating cavity 101 through the sealing structure 40 when performing the test. In at least one embodiment of the present application, three through holes 401 are provided on the sealing structure 40, and the three are arranged in a row. Among them, the through hole 401 located in the middle is connected to two heating cavities 101 at the same time, and the through holes 401 located on both sides are connected to one heating cavity 101 respectively. The sealing structure 40 includes a foam 41 and a sealing plate 42 arranged in a stacked manner. The foam 41 and the sealing plate 42 are both rectangular plate structures. The foam 41 is located between the main body 10 and the sealing plate 42. The foam 41 is used to reduce the noise generated when the fan 30 is running. The sealing plate 42 is located on the side of the foam 41 away from the main body 10. In at least one embodiment of the present application, the sealing plate 42 is made of antistatic wood.

[0060] In at least one embodiment of the present application, a temperature sensor (not shown) for sensing the ambient temperature in the heating cavity 101 and a temperature sensor (not shown) for sensing the temperature of the storage device 200 are further provided in the heating cavity 101. The temperature sensor provides the sensed temperature to the test platform 2, and the test platform 2 controls the operation of the heating structure 20 and the fan 30 according to the sensed temperature. The test platform 2 can control the heating cover 1 to switch between the preheating stage, the heating stage, and the cooling stage.

[0061] The test platform 2 has a plurality of slots (not shown) for providing a space for inserting the storage device 200 to establish an electrical connection between the test platform 2 and the storage device 200 .

[0062] Specifically, the working principle of the testing device 100 is as follows:

[0063] When the temperature of the storage device 200 accommodated in the heating cavity 101 needs to be raised (i.e., the preheating stage and the heating stage), the heating cover 1 is first covered and set on the test platform 2 with the storage device 200 inserted, so that most of the storage device 200 is set in the corresponding heating cavity 101 through the through hole 401 and is located in the second channel 1014. The heating structure 20 starts to work, so that the heat generating part 21 generates heat to quickly heat the air in the first channel 1012 through the multiple conduction parts 23. Driven by the fan 30, the heated air in the first channel 1012 flows downward through the fan 30 into the second channel 1014, and heats the storage device 200 located in the second channel 1014. Further, in the preheating stage, when the temperature in the heating cavity 101 reaches a predetermined temperature, the heating structure 20 stops working; in the heating stage, when the temperature in the heating cavity 101 reaches a specified temperature, the heating structure 20 stops working. Among them, the predetermined temperature is less than the specified temperature. In at least one embodiment of the present application, the predetermined temperature can be set as required. For example, when the test environment temperature of the storage device 200 is 80 degrees, the predetermined temperature can be set to 70 degrees, and the specified temperature can be higher than the test environment temperature and less than the value of the warning temperature. Among them, the warning temperature can be 100 degrees. By controlling the heating power of the heating structure 20 and controlling the speed of the fan 30, the time for the temperature of the storage device 200 accommodated in the heating cavity 101 to rise to the predetermined temperature is less than the predetermined heating time length. In at least one embodiment of the present application, under the joint action of the heating structure 20 and the fan 30, the predetermined heating time length is 120 seconds.

[0064] When the temperature of the storage device 200 accommodated in the heating cavity 101 needs to be lowered, the heating structure 20 stops working, and the fan 30 introduces cold air from the outside of the heating cover 1 into the heating cavity 101, and the temperature of the heating cavity 101 is lowered according to the introduced cold air. The cold air enters the second channel 1014 and cools the storage device 200 in the second channel 1014. Under the action of the fan 30, the time required for the temperature of the storage device 200 accommodated in the heating cavity 101 to drop to a safe temperature range is less than the predetermined cooling time length. In at least one embodiment of the present application, the predetermined cooling time length is 120 seconds.

[0065] The heating cover 1 and the testing device 100 having the heating cover 1 can achieve rapid temperature rise of the surrounding environment of the storage device 200 and reduce the testing cost by placing the storage device 200 in the heating cavity 101 of the heating cover 1; the fan 30 forms an airflow circulation in the heating cavity 101, which can make the temperature distribution in the heating cavity 101 uniform, thereby ensuring that the components at different positions on the storage device 200 are at the same test temperature during the test. At the same time, the sealing structure 40 can maintain the temperature stability in the heating cavity 101, thereby maintaining the stability of the test environment temperature of the storage device 200.

[0066] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
