[0036] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1 and Figure 2The present embodiment provides a high-temperature test device 100 for a solid-state hard disk, which includes a test box 10, an air inlet duct 20, an air outlet duct 30, a heating component 40, a detection component and a test component (not shown). A plurality of test stations 11 are provided in the test box 10. The test station 11 is used to install a solid-state hard disk (not shown). An air inlet 12 and an air outlet 13 are provided at both ends of the test box 10. A fan 21 is provided at the top of the test box 10. The air inlet duct 20 includes a first air duct 22 and a second air duct 23 connected in sequence. The first air duct 22 is provided at the top of the test box 10. The first air duct 22 is connected to the fan 21. The second air duct 23 is provided on the side of the test box 10. The second air duct 23 is connected to the air inlet 12. One end of the air outlet duct 30 is connected to the air outlet 13. A heat exchanger 31 is provided in the air outlet duct 30. The heating component 40 is provided outside the test box 10 for heating the test box 10. The detection assembly includes a plurality of temperature detection components. The plurality of temperature detection components are arranged in the test box 10 and are used to detect the temperature of the test box 10. The test assembly is used to detect the working state of the solid state hard disk.

[0039] Specifically, the test station 11 in this embodiment is fixed on the back plate of the test box 10. It can be understood that the solid state drive is fixed on the test station 11 by screws, and the power line and the signal line are connected to the solid state drive through the back plate of the test box 10 to enable the solid state drive to work normally. The signal line is connected to the test component so that the test component can detect the working status of the solid state drive.

[0040] It should be noted that the SSD high temperature testing device 100 of this embodiment performs stress testing on the SSD by simulating a high temperature environment to check its performance and reliability. The test component in this embodiment can detect the read and write speed, data storage capacity and overall stability of the SSD.

[0041] In order to reduce the temperature of the test box 10 and dissipate heat for the solid-state hard disk, in this embodiment, air inlets 12 and air outlets 13 are provided on both sides of the test box 10 so that air can flow in the test box 10, thereby taking away heat. In this embodiment, the test stations 11 are arranged at intervals and staggered in the test box 10. It can be understood that the solid-state hard disks are arranged at intervals and staggered in the test box 10, which reduces the thermal cascade to a certain extent. That is, the heat of the previous solid-state hard disk arranged along the wind direction will be transferred to the next solid-state hard disk. The test station 11 is set as a staggered structure, which increases the spacing between the fixed hard disks arranged along the wind direction and reduces the influence of the previous fixed hard disk on the next fixed hard disk. In addition, setting the test station 11 as a staggered structure can enhance the turbulence effect and improve the air convection heat exchange effect.

[0042] Further, the test station 11 includes a support frame 111. The support frame 111 is used to install the solid state drive. A heat dissipation fin 112 is provided below the support frame 111. It can be understood that the heat dissipation fin 112 increases the heat exchange area and enhances the heat exchange effect on the solid state drive.

[0043] Furthermore, a temperature averaging plate is provided on the support frame 111. Specifically, the area of ​​the temperature averaging plate is the same as the area of ​​the upper surface of the support frame 111. The temperature averaging plate is provided between the support frame 111 and the solid state drive, and is used to evenly distribute the heat of the solid state drive on the support frame 111. The temperature averaging plate can be a graphene plate, a metal plate or other structure to accelerate the heat transfer between the solid state drive and the support frame 111.

[0044] The air inlet duct 20 of this embodiment includes a first air duct 22 and a second air duct 23. The directions of the first air duct 22 and the second air duct 23 are perpendicular to each other, so that the air inlet duct 20 is "L" shaped, which is convenient for introducing the air from the fan 21 on the top of the test box 10 into the air inlet 12 on the side of the test box 10.

[0045] Since the direction of the second air duct 23 in this embodiment is perpendicular to the direction of the air inlet 12, in order to guide the wind direction of the second air duct 23 to change direction, a plurality of arc-shaped air guide plates 231 are arranged in the second air duct 23 in this embodiment. Specifically, the air guide plates 231 are arranged at intervals in the vertical direction. The tangent of the first side of the arc-shaped air guide plate 231 is arranged along the extension direction of the second air duct 23, and the tangent of the second side is arranged along the tangent of the second side along the air inlet direction of the air inlet 12, and the air guide plate 231 is bent toward the air guiding direction of the second air duct 23, so that when the air in the second air duct 23 passes through the air guide plate 231, the flow direction changes from the vertical flow direction to the horizontal flow direction and enters from the air inlet 12.

[0046] Optionally, in this embodiment, the first side of the air guide plate 231 is fixed to the side wall of the second air duct 23. The second side of the air guide plate 231 is spaced apart from the air inlet 12 so that part of the air passes through the air guide plate 231 and flows to the next air guide plate 231. In other embodiments, the second side of the air guide plate 231 may be fixedly connected to the air inlet 12, which is not limited in the present invention.

[0047] Furthermore, a vent hole 232 is provided on the air guide plate 231. The axial direction of the vent hole 232 is consistent with the extension direction of the second air duct 23. It can be understood that the air guide plate 231 can distribute the flow in the horizontal direction, and the vent hole 232 can ensure a part of the flow in the vertical direction, and the air flow of the fan 21 is distributed in the horizontal and vertical directions, ensuring that the test box 10 has a uniform flow distribution from top to bottom.

[0048] Furthermore, an arc-shaped transition plate 233 is provided at the connection between the first air duct 22 and the second air duct 23. Specifically, in this embodiment, an arc-shaped transition plate 233 is also provided below the second air duct 23. The transition plate 233 can avoid the formation of eddy flow areas at the upper and lower wind direction corners of the second air duct 23, thereby improving the utilization rate of wind.

[0049] The air inlet 12 and the air outlet 13 in this embodiment are provided with a perforated plate 14. Specifically, the perforated plate 14 is provided with holes evenly spaced. The flowing air can enter the test box 10 or flow out of the test box 10 through the perforated plate 14. Optionally, in this embodiment, the perforated plate 14 is configured as a square perforated plate. The perforated plate 14 is configured as a sheet metal stainless steel perforated plate. In other embodiments, the perforated plate 14 can be configured as a circular perforated plate, and the perforated plate can also be configured as other materials, which is not limited by the present invention.

[0050] In order to test the temperature uniformity of the test box 10, the temperature detection member of the present embodiment includes a first temperature detection member and a plurality of second temperature detection members. The first temperature detection member is located at the center of the test box 10, and the second temperature detection members are evenly arranged along the edge of the test box 10. Specifically, the test box 10 in the present embodiment is a square box. There are four second temperature detection members, which are respectively arranged at the four vertex corners of the test box 10. It can be understood that the temperature detection member and the test station 11 are both arranged on the back plate of the test box 10 so that the temperature detection member can be close to the solid state drive to be tested. By respectively arranging the temperature detection members at the four vertex corners and the center position of the test box 10, the temperature of each part of the test box 10 can be fed back more accurately, thereby feeding back the temperature difference of each part in the test box 10.

[0051] This embodiment also provides a thermal management method for a solid state hard disk high temperature testing device 100, which is applied to the solid state hard disk high temperature testing device 100, and the steps include:

[0052] Install the solid state drive on the test station 11 and make electrical connections to the solid state drive to make the solid state drive work normally;

[0053] The fan 21 is started to dissipate heat from the test box 10; at the same time, the heating component is started to heat the test box 10;

[0054] When the sum of the differences between the temperature values ​​detected by the temperature detection component and the first preset value is greater than the second preset value, the wind speed of the fan 21 is increased and the power consumption of the heating component is reduced; when the sum of the differences between the temperature values ​​detected by the temperature detection component and the first preset value is less than the second preset value, the wind speed of the fan 21 is reduced and the power consumption of the heating component is increased.

[0055] Specifically, the number of temperature detection components in this embodiment is five. The first preset value is set to 125°C, the second preset value is set to 5°C, and the third preset value is set to -5°C. When the sum of the differences between the temperature values ​​of the five temperature detection components and 125°C is greater than 5°C, the wind speed of the fan 21 is increased and the power consumption of the heating component is reduced, thereby reducing the temperature of the test box 10; when the sum of the differences between the temperature values ​​of the five temperature detection components and 125°C is less than -5°C, the wind speed of the fan 21 is reduced and the power consumption of the heating component is increased, thereby increasing the temperature of the test box 10.

[0056] In summary, the embodiment of the present invention provides a solid state hard disk high temperature testing device 100 and a thermal management method thereof. By providing a fan 21, an air inlet duct 20 and an air outlet duct 30, the heat of the test box 10 can be taken away, the temperature of the test box 10 can be lowered, and the heat dissipation effect of the product can be improved; by providing a heating component 40, the heat of the test box 10 can be increased; raising and lowering the temperature of the test box 10 can ensure that the test box 10 is maintained at a specified temperature value; by providing a temperature detection component, the temperature of each point in the test box 10 can be detected to ensure the uniformity of the temperature of each solid state hard disk. The present invention can ensure that the solid state hard disk high temperature testing device 100 is maintained at a specified temperature value, ensure the uniformity of the temperature of each product, and improve the heat dissipation effect of the tested product.

[0057] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
