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

[0055] The test device 100 heats the cover 1 and the test platform 2. The heating cover 1 is movably covered on the test platform 2. When performing a high-temperature environment test, the heating cover 1 is covered on the test platform 2 so that the heating cover 1 and the test platform 2 cooperate to form a closed space, and the test platform 2 is used to control the heating cover 1 to perform a heating operation to heat the closed space. When performing a room temperature environment test, the test platform 2 is used to control the heating cover 1 to perform a cooling operation to cool the closed space.

[0056] The heating cover 1 comprises a shell 10 , at least one heating structure 20 and at least one heat dissipation structure 30 .

[0057] The shell 10 is movably covered on the test platform 2. The shell 10 is a hollow structure. In at least one embodiment of the present application, the shell 10 is made of anti-static wood. The shell 10 includes a top plate 11 and a plurality of side plates 12 extending vertically downward from the edge of the top plate 11.

The cover plate 15 is arranged parallel to the top plate 11 and vertically arranged at one end of the partition 14 close to the top plate 11. Every four partitions 14 are connected end to end and cooperate with a cover plate 15 to enclose a receiving cavity 101. Among them, different receiving cavities 101 may have different sizes. In at least one embodiment of the present application, three receiving cavities 101 are arranged in the housing 10. Among them, the two receiving cavities 101 located at the edge have the same size, and the width of the receiving cavity 101 located in the middle is greater than the width of the receiving cavity 101 located at the edge. Each receiving cavity 101 contains at least one heating structure 20 and at least one heat dissipation structure 30. In at least one embodiment of the present application, the receiving cavity 101 located in the middle contains two heating structures 20 and two heat dissipation structures 30; the two receiving cavities 101 located at the edge contain one heating structure 20 and one heat dissipation structure 30 respectively.

[0059] Each receiving cavity 101 is further provided with a partition plate 16. The partition plate 16 is arranged parallel to the top plate 11 and perpendicular to the partition plate 14. The partition plate 16 is used to separate the corresponding receiving cavity 101 into a heat dissipation cavity 1011 and a heating cavity 1013. The heat dissipation cavity 1011 and the heating cavity 1013 are sealed and isolated from each other. The two partition plates 14 arranged opposite to each other for enclosing the heat dissipation cavity 1011 are each provided with at least one through hole 141 (such as Figure 4 As shown). The through hole 141 is used to establish an air circulation path between the heat dissipation cavity 1011 and the outside of the shell 10. In at least one embodiment of the present application, the size of the heat dissipation cavity 1011 and the heating cavity 1013 can be adjusted by adjusting the position of the partition plate 16 on the partition 14. Each heat dissipation cavity 1011 contains at least one heat dissipation structure 30; each heating cavity 1013 contains at least one heating structure 20. In at least one embodiment of the present application, the cross-section of the partition 14 extending along the length direction of the receiving cavity 101 can be L-shaped in the vertical direction. That is, along the length direction of the receiving cavity 101, the length of the heat dissipation cavity 1011 is slightly larger than the length of the heating cavity 1013.

[0060] The heating structure 20 is used to raise the ambient temperature in the heating cavity 1013 to within the target temperature range. In at least one embodiment of the present application, the target temperature range is 40 degrees to 85 degrees. The heating structure 20 is accommodated in the heating cavity 1013. The heating structure 20 includes a heating part 21 and a conducting part 23. The heating part 21 is arranged on the surface of the partition plate 16 away from the top plate 11. The heating part 21 is roughly flat and extends in a direction parallel to the partition plate 16. The heating part 21 is provided with at least two positioning holes 212. The positioning hole 212 is roughly square. The positioning hole 212 is used to cooperate with the conducting part 23 to locate the relative position of the heating part 21 and the conducting part 23. In at least one embodiment of the present application, the heating power of the heating part 21 can be adjusted according to demand. The conducting part 23 includes a connecting member 231, a positioning block 232 and a plurality of conducting members 233. The connecting member 231 is roughly flat. The connecting member 231 is arranged in parallel with the heating part 21, and is fitted on the surface of the heating part 21 away from the partition plate 16. The positioning block 232 is protrudingly arranged on the surface of the connecting member 231 opposite to the heating part 21. The positioning block 232 can be accommodated in the positioning hole 212 to prevent the conductive part 23 from moving in a direction parallel to the heating part 21. A plurality of conductive members 233 are arranged in parallel with each other, and are vertically fixed on the surface of the connecting member 231 away from the top plate 11. At least one storage device 200 is arranged between two adjacent conductive members 233. A plurality of conductive members 233 are accommodated in the heating cavity 1013, and form a serrated structure.

[0061] The heat dissipation structure 30 is accommodated in the heat dissipation cavity 1011. The heat dissipation structure 30 is used to cool the heating structure 20 when performing a cooling operation. The heat dissipation structure 30 includes a refrigeration part 31 and a plurality of heat dissipation parts 32. The refrigeration part 31 is arranged on the positioning block 232. The refrigeration part 31 is generally in the shape of a plate. In at least one embodiment of the present application, the size of the refrigeration part 31 is smaller than the size of the heating part 21, and the two are arranged in alignment along the central axis. The plurality of heat dissipation parts 32 are arranged in parallel with each other and are vertically fixed on the surface of the refrigeration part 31 opposite to the heating structure 20. In at least one embodiment of the present application, the refrigeration part 31 is a thermoelectric cooling (TEC) device. Specifically, when the heat dissipation structure 30 is working, the heat on the conductive member 233 is absorbed by the refrigeration part 31 and released by the heat dissipation part 32, and the released heat can be further released to the outside of the housing 10 through the corresponding heat dissipation port 112. The plurality of heat dissipation parts 32 are accommodated in the heat dissipation cavity 1011 and form a serrated structure.

[0062] The heating cover 1 further includes at least one heating auxiliary fan 40. The heating auxiliary fan 40 is used to drive the air circulation in the heating cavity 1013 to strengthen the heat convection of the lower area of ​​the heating cavity 1013. The heating auxiliary fan 40 is located on the side of the conduction part 23. In at least one embodiment of the present application, two heating auxiliary fans 40 are arranged in each heating cavity 1013, and the two are symmetrically arranged. In the horizontal direction, the conduction part 23 is arranged between the two heating auxiliary fans 40. The rotation speed of the heating auxiliary fan 40 can be adjusted according to demand. Specifically, when the heating part 21 generates heat, the conduction part 23 transfers the heat generated by the heating part 21 to the heating cavity 1013. Driven by the heating auxiliary fan 40, the air in the heating cavity 1013 flows, which can accelerate the heat exchange between the conduction part 23 and the heating cavity 1013. When the heating auxiliary fan 40 is working, the air inside the heating cavity 1013 circulates, which can ensure that multiple storage devices 200 and components at different positions on any storage device 200 are at the same test temperature when testing. That is, the heating auxiliary fan 40 can ensure that the temperature in the heating cavity 1013 is evenly distributed. In at least one embodiment of the present application, when it is necessary to heat up the ambient temperature of the heating cavity 1013, the speed of the heating auxiliary fan 40 can be set to a first predetermined speed; when it is necessary to cool down the ambient temperature in the heating cavity 1013, the speed of the heating auxiliary fan 40 can be set to a second predetermined speed. Among them, the first predetermined speed and the second predetermined speed can be the same or different. In other embodiments, when it is necessary to heat up the ambient temperature of the heating cavity 1013, the speed of the heating auxiliary fan 40 can also be switched between multiple different speeds. In at least one embodiment of the present application, the axis of the heating auxiliary fan 40 extends in the horizontal direction.

[0063] The heating cover 1 further includes at least one heat dissipation auxiliary fan 50. The heat dissipation auxiliary fan 50 is used to drive the air circulation in the heat dissipation cavity 1011, and accelerate the air flow speed between the heat dissipation cavity 1011 and the outside of the shell 10. The heat dissipation auxiliary fan 50 is located on the side of the heat dissipation portion 32, and partially passes through the cover plate 15, and is exposed relative to the receiving cavity 101. In at least one embodiment of the present application, the rotation speed of the heat dissipation auxiliary fan 50 can be adjusted according to demand. In at least one embodiment of the present application, the axis of the heat dissipation auxiliary fan 50 extends in a vertical direction. In at least one embodiment of the present application, the heat dissipation auxiliary fan 50 is fixedly arranged at the heat dissipation port 112, and is located in the heat dissipation cavity 1011 at a position beyond the heating cavity 1013.

[0064] In at least one embodiment of the present application, a temperature sensor (not shown) for sensing the ambient temperature in the heating cavity 1013 is further provided in the heating cavity 1013. The temperature sensor provided in the heating cavity 1013 cooperates with the temperature sensor built into the storage device 200 to provide the sensed temperature to the test platform 2, and the test platform 2 controls the operation of the heating structure 20, the heat dissipation structure 30, the heating auxiliary fan 40, and the heat dissipation auxiliary fan 50 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.

[0065] 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 .

[0066] Specifically, the working principle of the testing device 100 is as follows:

[0067] When the ambient temperature of the heating cavity 1013 needs to be raised (i.e., the preheating stage and the heating stage), the heating cover 1 is first covered on the test platform 2 with the storage device 200 inserted, so that the exposed part of the storage device 200 relative to the test platform 2 is accommodated in the heating cavity 1013. At the same time, the heating cavity 1013 cooperates with the test platform 2 to form a closed space. The test platform 2 controls the heating part 21 to generate heat, and transfers the heat to the heating cavity 1013 through the conduction part 23, thereby heating the storage device 200 accommodated in the heating cavity 1013. At the same time, driven by the heating auxiliary fan 40, the air flow in the heating cavity 1013 can accelerate the heat exchange between the conduction part 23 and the heating cavity 1013. Further, in the preheating stage, when the temperature in the heating cavity 1013 reaches a predetermined temperature, the heating structure 20 stops working; in the heating stage, when the temperature in the heating cavity 1013 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 rotation speed of the heating auxiliary fan 40, the time for the ambient temperature of the heating cavity 1013 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 heating auxiliary fan 40, the predetermined heating time length is 120 seconds.

[0068] When the ambient temperature of the heating cavity 1013 needs to be cooled down, the heating structure 20 stops working, and the heating auxiliary fan 40 can be maintained in a working state. At the same time, the refrigeration unit 31 and the heat dissipation unit 32 work, and the heat dissipation auxiliary fan 50 starts working. The heat in the heating cavity 1013 is absorbed by the refrigeration unit 31 and the conduction unit 23 and released through the heat dissipation unit 32. The released heat can be further released to the outside of the housing 10 through the corresponding heat dissipation port 112, thereby reducing the temperature in the heating cavity 1013. By setting the working current of the refrigeration unit 31 and the speed of the heat dissipation auxiliary fan 50, the control of the refrigeration power can be achieved, so that the time required for the temperature of the storage device 200 accommodated in the heating cavity 1013 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.

[0069] The above-mentioned heating cover 1 and the testing device 100 having the heating cover 1, by dividing the receiving cavity 101 of the heating cover 1 into a heat dissipation cavity 1011 and a heating cavity 1013, and making the heating cavity 1013 cooperate with the testing platform 2 to form a closed cavity, so that there is no heat convection between the closed cavity and the outside of the heating cover 1, can improve the heat preservation effect of the heating cover 1, and thus maintain the stability of the test environment temperature of the storage device 200. At the same time, the heat dissipation structure 30 contained in the semi-enclosed heat dissipation cavity 1011 is used to cool the environment in the heating cavity 1013, and the temperature reduction speed in the heating cavity 1013 can be accelerated during the cooling operation.

[0070] 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.
