Technical Field

[0001] The present application relates to the field of solid state drive testing, and in particular to a solid state drive testing incubator. Background Art

[0002] Solid-state drives (SSDs) are an important part of modern computers, and their performance and quality directly affect the operating speed and stability of the system. After SSDs are produced, they need to undergo a variety of tests and pass them before they can be circulated in the market. One of the more important tests is to detect the operating status of SSDs at higher ambient temperatures and whether they can operate normally.

[0003] Although traditional temperature chamber equipment can simulate various temperature environments that SSDs may encounter to a certain extent, its temperature control accuracy is often not high enough to meet the needs of precise control of subtle temperature changes. More importantly, the design of the temperature chamber usually only focuses on whether the temperature of the overall space meets the test standards, while ignoring the precise control of the temperature of each SSD internal chip. Summary of the invention

[0004] In order to accurately control the test temperature of each product, the present application provides a solid state drive test temperature chamber.

[0005] The solid state drive test incubator provided in this application adopts the following technical solution: A solid state hard disk test incubator, comprising: The box body is provided with a test area, wherein a partition is provided in the test area so as to form a ring-shaped test air duct in the test area; A temperature control component, disposed in the test air duct, for changing the air flow temperature in the test air duct; The wind power component is arranged in the test air duct and is used to generate a circulating airflow in the test air duct.

[0006] By adopting the above technical solution, the wind power component forms a circulating airflow in the test air duct. The circulating airflow allows heat to pass through the solid-state hard disk quickly and repeatedly, so the temperature difference between different solid-state hard disks can be smaller, thereby accurately controlling the test temperature of each product.

[0007] Preferably, a test box door is provided on one side of the box body, and the test box door is used to open or close the test area; the test air duct is divided into a straight portion and a turning portion, the straight portion is directly connected to the test box door, and the straight portion is used for placing products; the two ends of the turning portion are respectively connected to the two straight portions, and the turning portion is used for setting the wind power component.

[0008] By adopting the above technical solution, firstly, after opening the test chamber door, the staff can take the solid-state hard disk more conveniently, which makes it easier for the staff to use the test chamber; secondly, the wind power component is located at the turning part, which can also increase the flow speed of the circulating airflow, so the temperature uniformity can be further improved, thereby more accurately controlling the test temperature of each product.

[0009] Preferably, two wind power components are provided, and the two wind power components are respectively arranged at the two turning parts; the partition is provided with partition connecting holes, and the partition connecting holes connect the two straight parts to form a branch confluence part, and the branch confluence part does not accommodate products so that the circulating airflow has two circulation branches, and one circulation branch has one temperature control component.

[0010] By adopting the above technical solution, one circulation branch corresponds to a wind power component, a temperature control component and a group of products. This design method can test more products while maintaining the rapid flow of circulating airflow and the space utilization of the test temperature chamber, thereby maintaining temperature control accuracy while improving test efficiency.

[0011] Preferably, the box body is provided with a host area, and the host area is located on a side of the test area away from the test box door; the straight part close to the host area is used for product installation, and a wire hole is provided between the host area and the straight part.

[0012] By adopting the above technical solution, the host area is the core of the test incubator, which is used to realize various tests, performance, reliability and other indicators of the solid-state hard disk. There will be multiple sensors on the solid-state hard disk, and the data of the sensors needs to be transmitted to the test incubator through data cables. Therefore, a wire hole needs to be set between the straight part and the host area. Therefore, the special setting of the product position can realize the normal product testing without interfering with the circulating airflow by the cable structure.

[0013] Preferably, the wind power component is arranged on one end of the turning portion away from the test chamber door; the temperature control component is arranged in the straight portion away from the test chamber door, and the airflow leaving the wind power component first passes through the temperature control component and then passes through the product.

[0014] By adopting the above technical solution, firstly, there are products, temperature control components and wind power components in the straight part away from the test chamber door, and these components will occupy a part of the test air duct space, so the wind power component is located in the straight part away from the test chamber door, and there are no components in the straight part close to the test chamber door, thereby maintaining the flow stability of the circulating airflow; secondly, the airflow passes through the product immediately after being heated, which can reduce heat waste and thus reduce testing costs.

[0015] Preferably, the temperature control component includes a heating wire and an evaporator, and the evaporator is farther away from the wind power component than the heating wire.

[0016] By adopting the above technical solution, since the ventilation structure of the evaporator is scaly, the airflow can be more uniform after passing through the evaporator, so that the temperature can be more uniform, which helps to improve the temperature control accuracy.

[0017] Preferably, the straight portion away from the test chamber door is connected to be provided with a drainage hole and an exhaust hole, the drainage hole is used to drain condensed water, and the exhaust hole is used to drain excess gas.

[0018] By adopting the above technical solution, firstly, the evaporator will absorb heat during operation, so condensed water may be generated, so a corresponding drainage hole is set; secondly, the exhaust hole will be connected to dry gas to discharge excess gas, thereby maintaining the dryness of the circulating airflow.

[0021] Preferably, the wind power component includes a fan and a swinging drive component. There are multiple fans, and the multiple fans are distributed in the vertical direction. The fans are slidingly arranged, and the fans make circular motion around the center of the bend; the swinging drive component is connected to the fan to make the fan make reciprocating motion.

[0022] By adopting the above technical solution, when the stroke of the straight part is long, in order to continue to maintain a small volume of the test temperature chamber, the fan can be allowed to reciprocate between the two ends of the turning part through a swinging drive member, so that the airflow can be pressurized alternately in the two straight parts, thereby forming a faster and more stable circulating airflow without changing the volume of the fan, thereby increasing the test efficiency while maintaining the temperature control accuracy.

[0023] Preferably, a transmission connecting hole is provided on the outer wall of the turning portion, and the transmission connecting hole extends in a circle around the bend center of the turning portion; one fan is matched with one swinging driving component, and the swinging driving component includes an epitaxial block, a swinging pulley, a swinging belt and a swinging motor, one end of the epitaxial block is connected to the fan, and the other end passes through the transmission connecting hole, two swinging pulleys are provided, and the two swinging pulleys are respectively located at the two ends of the swing stroke of the fan, the swinging belt is sleeved between the two swinging pulleys, one side of the swinging belt is fixedly connected to the epitaxial block, and the swinging motor is connected to the swinging pulley.

[0024] By adopting the above technical solution, multiple fans can move asynchronously, so that each straight section will have at least one fan to boost the airflow, so the flow rate uniformity of the circulating airflow can be maintained, thereby improving the temperature control accuracy.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: Because the wind power component forms a circulating airflow in the test air duct, the circulating airflow allows heat to pass through the SSD quickly and repeatedly, so the temperature difference between different SSDs can be small, so that the test temperature of each product can be accurately controlled; One circulation branch corresponds to a wind power component, a temperature control component and a group of products. This design method can test more products while maintaining the rapid flow of circulating air and the space utilization of the test temperature chamber, thereby maintaining the temperature control accuracy and improving the test efficiency; When the stroke of the straight part is long, in order to continue to maintain a small volume of the test temperature chamber, the fan can be made to reciprocate between the two ends of the bend through a swing drive, so that the airflow can be pressurized alternately in the two straight parts, thereby forming a faster and more stable circulating airflow without changing the volume of the fan, thereby increasing the test efficiency while maintaining the temperature control accuracy.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0033] The embodiment of the present application discloses a solid state hard disk test incubator. Example 1

[0034] Reference Figure 1 and Figure 2 The solid state drive test temperature box includes a box body 1, a temperature control component 4 and a wind power component 5. The box body 1 is provided with a test area 11, and a partition 2 is formed in the test area 11. The partition 2 allows the test area 11 to form a ring-shaped test air duct 3; the temperature control component 4 is arranged in the test air duct 3, and the temperature control component 4 is used to change the air flow temperature in the test air duct 3; the wind power component 5 is arranged in the test air duct 3, and the wind power component 5 allows a circulating airflow to be formed in the test air duct 3. With the help of the circulating airflow, heat can pass through the solid state drive quickly and repeatedly, so that the temperature difference between different solid state drives can be small, thereby accurately controlling the test temperature of each product.

[0035] Reference Figure 2 and Figure 3 In order to facilitate the staff to use the test temperature box while further improving the temperature uniformity and realizing more precise control of the test temperature of each product, the following settings are correspondingly arranged: a test box door 6 is installed on one side of the box body 1, and the test box door 6 opens or closes the test area 11 by hinged rotation. At the same time, the test air duct 3 is divided into a straight portion 31 and a turning portion 32. The straight portion 31 is arranged in parallel with the test box door 6, one of the straight portions 31 is directly connected to the test box door 6, and the straight portion 31 is also used for product placement, and the two ends of the turning portion 32 are respectively connected to the two straight portions 31, and the turning portion 32 is also used for the wind power component 5 to be arranged. In summary, the product can be directly seen by opening the test box door 6, which is convenient for the staff to take the product. At the same time, the wind power component 5 can supplement and enhance the flow velocity at the turning portion 32, thereby improving the flow velocity of the circulating airflow, so that the temperature uniformity can be further improved, thereby more accurately controlling the test temperature of each product.

[0036] Reference Figure 2 and Figure 3 In order to take into account the space utilization of the test temperature chamber, the rapid flow of the circulating airflow and the number of products during the test, the above three factors correspond to the following settings. Two wind power components 5 will be provided, and the two wind power components 5 are respectively located at the two turning parts 32. At the same time, the partition 2 will also be provided with a partition connecting hole 21. The partition connecting hole 21 will connect the two straight parts 31 to form a branch confluence part 22. No product is placed at the branch confluence part 22. In this way, under the action of the two wind power components 5, the circulating airflow will have two connected circulation branches in the test air duct 3. Each circulation branch has a group of products, a wind power component 5 and a temperature control component 4. Therefore, the number of components in each circulation branch will not be too many, and the flow rate of the circulating airflow will not be reduced. One circulation branch can test a group of products, which can make full use of the space of the test temperature chamber and enable more products to be tested at the same time, thereby maintaining the temperature control accuracy while improving the test efficiency.

[0037] Reference Figure 2 and Figure 3 The test incubator will perform various tests on the solid-state hard disk, as well as evaluations of performance, reliability and other indicators, so the test incubator will have a host area 12. In order to obtain real-time test data of the solid-state hard disk, there is a sensor on the solid-state hard disk. After the sensor obtains the data, it needs to be transmitted to the relevant control and processing devices in the host area 12 for processing, so a wire hole 121 will be provided between the host area 12 and the straight portion 31. On this basis, in order to maintain the flow rate and flow stability of the circulating airflow, the straight portion 31 close to the host area 12 is used for product placement, so that there will be no cables to hinder the circulating airflow.

[0038] Reference Figure 2 and Figure 3 In this embodiment, the flow rate of the circulating airflow will decrease and the flow stability will decrease when there are obstructions. Therefore, in order to maintain the flow rate and flow stability of the circulating airflow in each circulation branch, the wind power component 5 will be arranged on the end of the turning portion 32 away from the test box door 6, that is, the wind power component 5 will be directly arranged opposite to the straight portion 31 away from the test box door 6, and the temperature control component 4 will also be arranged in the straight portion 31 away from the test box door 6, and in each circulation branch, the temperature control component 4 is located between the wind power component 5 and the product, so that the airflow will pass through the product immediately after being heated to reduce heat waste, thereby reducing the testing cost.

[0039] Reference Figure 2 and Figure 3In order to allow the airflow to pass through the product more evenly to improve the temperature uniformity, the temperature control component 4 will include a heating wire 41 and an evaporator 42. The evaporator 42 is farther away from the wind power component 5 than the heating wire 41. In this way, the airflow can be more uniform with the help of the scaly ventilation structure of the evaporator 42, so that the temperature can be more uniform, which helps to improve the temperature control accuracy. At the same time, based on the structure of the temperature control component 4, the straight part 31 where the product is located will be connected to a drainage hole 311 and an exhaust hole 312. The drainage hole 311 is used to remove condensed water that may be generated during the operation of the evaporator 42, and the exhaust hole 312 will be connected to dry gas to remove excess gas, thereby maintaining the dryness of the circulating airflow.

[0040] In addition, in this embodiment, in order to compensate for the flow velocity of the airflow at the bend, an air guide plate 321 is further provided at one end of the bend portion 32 close to the test chamber door 6 , and the air guide plate 321 is extended in a circular arc.

[0041] The implementation principle of a solid-state hard disk test temperature box in an embodiment of the present application is as follows: because the wind power component 5 forms a circulating airflow in the test air duct 3, the circulating airflow can allow heat to pass through the solid-state hard disk quickly and repeatedly, so the temperature difference between different solid-state hard disks can be smaller, thereby accurately controlling the test temperature of each product. Example 2

[0042] Reference Figure 4 and Figure 5 , which is different from Example 1, is that when the stroke of the straight portion 31 is long, in order to continue to maintain a smaller volume of the test temperature box, the following settings are correspondingly arranged: the wind power component 5 includes a fan 51 and a swinging drive member 52, and a plurality of fans 51 are arranged, and the plurality of fans 51 are distributed along the vertical direction. The fan 51 is rotatably connected to the partition 2, and specifically, a hinge structure, such as a 360-degree hinge mechanism, or a rotating shaft structure, such as a 180-degree rotating shaft, the fan 51 is slidably arranged, and the fan 51 makes a circular motion around the center of the bend 32, and the swinging drive member 52 is connected to the fan 51 so that the fan 51 makes a reciprocating motion between the two ends of the bend 32, so that the two straight portions 31 in a circulation branch can be alternately pressurized for airflow, so that a faster and more stable circulating airflow can continue to be maintained without changing the volume of the fan 51, thereby increasing the test efficiency while maintaining the temperature control accuracy.

[0043] Reference Figure 4 and Figure 5Specifically, in order to realize the above-mentioned functions, the following configurations are correspondingly provided: a transmission connecting hole 7 is provided on the outer wall of the turning portion 32, and the transmission connecting hole 7 is distributed in a circular shape around the bending center of the turning portion 32 to form a virtual structure for an external component to drive the fan 51 to move. At the same time, a fan 51 will cooperate with a swing driving member 52, and the swing driving member 52 includes an extension block 521, a swing pulley 522, a swing belt 523 and a swing motor 524. One end of the extension block 521 is connected to the fan 51, and the other end is connected to the fan 51. The transmission connecting hole 7 is provided with two swing pulleys 522, and the two swing pulleys 522 are respectively located at the two ends of the swing stroke of the fan 51. The swing belt 523 is sleeved between the two swing pulleys 522. One side of the swing belt 523 is fixedly connected to the epitaxial block 521, and the other side movably passes through the epitaxial block 521, that is, it does not form a fixed connection relationship with the epitaxial block 521. The swing motor 524 is connected to the swing pulley 522, and the swing motor 524 drives one of the swing pulleys 522 to rotate.

[0044] Reference Figure 4 and Figure 5 The working principle of the wind power component is as follows: the swing motor 524 rotates the swing pulley 522, and the swing belt 523 rotates clockwise or counterclockwise during the rotation, so that the epitaxial block 521 moves clockwise or counterclockwise. When the epitaxial block 521 moves to the vicinity of another swing pulley 522 away from the swing motor 524, the swing motor 524 rotates the swing pulley 522 in the opposite direction, so that the epitaxial block 521 can slide in the opposite direction. In summary, the reciprocating swing of the fan 51 can be achieved by means of belt transmission, and multiple fans 51 can move asynchronously at the same time, so that each straight part 31 will have at least one fan 51 to pressurize its airflow, so the flow rate uniformity of the circulating airflow can be maintained, thereby also improving the temperature control accuracy.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
