Description

Technical Field

[0001] The present application relates to the field of testing technology, and in particular to a heating hood and a testing device. Background Art

[0002] Storage devices, such as dual in-line memory modules (DIMMs), are widely used in computer equipment such as computers, servers, and workstations. By installing multiple DIMMs, the available memory capacity of the computer can be increased.

Figure 6 The cross-section diagram along the VV direction when the adjustment structure 16 in the test device 100 is in the second position. The test device 100 is used to electrically connect multiple storage devices 200 at the same time and test the storage devices 200. The test device 100 can test multiple storage devices 200 at room temperature or high temperature at the same time. In one embodiment of the present application, multiple test devices 100 can be stacked on a rack (not shown) to achieve batch testing of a large number of storage devices 200; the test device 100 can also be placed on a desktop to achieve testing of a small number of storage devices 200. Among them, the small number can be 1-32.

[0069] 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. When performing a high temperature environment test, the heating cover 1 is mounted 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 heating cover 1 can cool the closed space. In at least one embodiment of the present application, the heating cover 1 is a semi-enclosed structure.

[0070] The heating cover body 1 includes a shell 11 and a heating structure 20. The shell 11 is movably covered on the test platform 2. The heating structure 20 is accommodated in the shell 11 and is used to heat the air in the shell 11. The shell 11 is a hollow structure. In at least one embodiment of the present application, the shell 11 is made of anti-static wood. The shell 11 includes a top plate 111 and a plurality of side plates 112. Among them, the top plate 111 extends along a first direction X, and the side plates 112 are perpendicularly arranged at the edge of the top plate 111, and extend along a second direction Y perpendicular to the first direction X.

[0071] The heating cover 1 further includes a plurality of receiving cavities 13. In at least one embodiment of the present application, three receiving cavities 13 are provided in the housing 10. Different receiving cavities 13 may have different sizes. In at least one embodiment of the present application, the two receiving cavities 13 located at the edge have the same size, and the width of the receiving cavity 13 located in the middle is greater than the width of the receiving cavity 13 located at the edge. The receiving cavity 13 extends along a third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y, and forms a rectangular coordinate system with the first direction X and the second direction Y.

[0072] Specifically, the receiving cavity 13 includes four side walls 131, a cover plate 132 and a bottom plate 134. The four side walls 131 are connected end to end, and cooperate with the cover plate 132 and the bottom plate 134 to form a receiving cavity 13. The cover plate 132 is arranged in parallel with the top plate 111, and is vertically arranged at one end of the side wall 131 close to the top plate 111. The bottom plate 134 is arranged in parallel with the top plate 111, and is vertically arranged at one end of the side wall 131 away from the top plate 111. In at least one embodiment of the present application, the receiving cavity 13 is made of a heat-insulating material. Among them, at least two symmetrically arranged shaft holes 1312 are provided on the two side walls 131 extending along the third direction Z, and a plurality of vents 1314 are provided on the other two side walls 131. In at least one embodiment of the present application, the shaft hole 1312 is arranged in the middle of the side wall 131. The shaft hole 1312 is used to allow the elements in the receiving cavity 13 to pass through. The vent 1314 is used to establish an air circulation path between the receiving chamber 13 and the outside. A notch 1342 is provided on the bottom plate 134. The notch 1342 is used to allow the storage device 200 to pass through the bottom plate 134 and be received in the receiving chamber 13 when the heating cover 1 is placed on the test platform 2. The receiving chamber 13 is further defined with an air inlet end 135 (such as Figure 3 ) and an air outlet end 136 (as shown) disposed opposite to the air inlet end 135. Figure 3 The airflow enters the receiving cavity 13 through the air inlet end 135 and flows out of the receiving cavity 13 through the air outlet end 136.

[0073] The heating cover 1 further includes a plurality of adjustment structures 16 and a plurality of limiting structures 17. In at least one embodiment of the present application, two adjustment structures 16 and two limiting structures 17 are provided in each receiving cavity 13. At least one adjustment structure 16 cooperates with the bottom plate 134 and the heating structure 20 to form a receiving cavity 300. In at least one embodiment of the present application, in the same receiving cavity 13, the adjustment structure 16 and the limiting structure 17 cooperate with the heating structure 20 to form a receiving cavity 300. The receiving cavity 300 is used to accommodate the storage device 200 when the heating cover 1 is covered on the test platform 2.

[0074] The two adjustment structures 16 are symmetrically arranged at two opposite ends of the receiving cavity 13. That is, one adjustment structure 16 is arranged at the air inlet end 135, and the other adjustment structure 16 is arranged at the air outlet end 136. The adjustment structure 16 can rotate between a first position and a second position in the receiving cavity 13, and can stay at any position between the first position and the second position as required. The adjustment structure 16 is used to adjust the state of the receiving cavity 300 by rotation. When the two adjustment structures 16 are both located at the first position, the receiving cavity 300 is in a sealed state. At the same time, a first airflow path P1 (such as Figure 5As shown in FIG. 1 ). The first airflow path P1 is the airflow from the air inlet end 135 directly into the area between the adjustment structure 16 and the cover plate 132 through the limiting structure 17 and then flows out from the air outlet end 136. When any one of the adjustment structures 16 leaves the first position, the accommodating cavity 300 is in an open state. When both adjustment structures 16 are in the second position, a second airflow path P2 (as shown in FIG. 1 ) is formed in the accommodating cavity 130. Figure 6 As shown). The first airflow path P1 and the second airflow path P2 do not overlap each other. Among them, the second airflow path P2 is an airflow that directly enters the area between the adjustment structure 16 and the bottom plate 134 from the air inlet end 135 through the limiting structure 17 and flows out from the air outlet end 136. At the same time, when the two adjustment structures 16 can also be located at any position between the first position and the second position, the first airflow path P1 and the second airflow path P2 exist in the receiving cavity 13 at the same time. That is, when the adjustment structure 16 is not in the first position and the second position, there is airflow in both the first airflow path P1 and the second airflow path P2; when the adjustment structure 16 is closer to the second position, the smaller the airflow in the first airflow path P1, and the larger the airflow in the second airflow path P2; when the adjustment structure 16 reaches the second position, there is airflow only in the second airflow path P2.

[0075] Specifically, the adjustment structure 16 includes a rotating shaft 161 and a rotating plate 162. The rotating shaft 161 extends along the first direction X and is perpendicular to the two side walls 131 extending along the third direction Z. The opposite ends of the rotating shaft 161 are received in two oppositely arranged shaft holes 1312 and can rotate in the shaft holes 1312. The rotating plate 162 is generally in the shape of a rectangular parallelepiped. The rotating plate 162 can rotate around the rotating shaft 161 under the drive of the rotating shaft 161. The rotating plate 162 includes a first end 1621 (such as Figure 5 As shown) and the second end 1622 (as Figure 5). The first end 1621 is disposed close to the bottom plate 134 and is always close to the bottom plate 134 during the rotation process. That is, the first end 1621 is always located in the second airflow path P2; the second end 1622 is disposed close to the cover plate 132 and is always close to the cover plate 132 during the rotation process. That is, the second end 1622 is always located in the first airflow path P1. In at least one embodiment of the present application, the rotating shaft 161 is disposed in the center of the rotating plate 162. In other embodiments, the position at which the rotating shaft 161 is disposed on the rotating plate 162 can be adjusted according to the setting position of the shaft hole 1312. For example, when the shaft hole 1312 is located close to the bottom plate 134, the rotating shaft 161 can be disposed at the first end 1621, and at the same time, the length of the first end 1621 is smaller than the length of the second end 1622. In at least one embodiment of the present application, the three rotating shafts 161 disposed at the air inlet end 135 in the three receiving cavities 13 are integrally formed, and the three rotating shafts 161 disposed at the air outlet end 136 in the three receiving cavities 13 are integrally formed. That is, when one rotating shaft 161 rotates, the three rotating plates 162 connected thereto are simultaneously driven to rotate.

[0076] Each limiting structure 17 corresponds to an adjustment structure 16. The limiting structure 17 is used to limit the rotation angle of the corresponding adjustment structure 16 in the receiving cavity 13. In the process of switching between the first position and the second position, the limiting structure 17 is used to limit the rotation angle of the adjustment structure 16 to less than 180 degrees. The limiting structure 17 includes a top limiting portion 171, a bottom limiting portion 172 and a middle limiting portion 173, and the connecting line between the three is arranged in a triangular shape. Among them, the top limiting portion 171 and the bottom limiting portion 172 are located between the side wall 131 and the corresponding adjustment structure 16, and the middle limiting portion 173 is located between the adjustment structure 16 and the heating structure 20. In the second direction Y, the top limiting portion 171 and the bottom limiting portion 172 are located on the same straight line. The top limiting portion 171 is vertically arranged on the inner surface of the cover plate 132. A top limiting groove 1711 (such as Figure 5 The top limiting groove 1711 is used to receive the second end portion 1622 when the adjustment structure 16 is in the second position, and to limit the rotation angle of the second end portion 1622 when it rotates toward the bottom plate 134. The bottom limiting portion 172 is vertically arranged on the inner surface of the bottom plate 134 and is arranged opposite to the top limiting portion 171. The bottom limiting portion 172 is provided with a bottom limiting groove 1721 (as shown in FIG. Figure 6The bottom limiting groove 1721 is used to receive the first end portion 1621 when the adjustment structure 16 is in the first position, and to limit the rotation angle of the first end portion 1621 when it rotates toward the cover plate 132. The middle limiting portion 173 is fixedly disposed on the heating structure 20 received in the receiving cavity 13, and is disposed opposite to the gap between the top limiting portion 171 and the bottom limiting portion 172. The middle limiting portion 173 has a top abutting surface 1731 (as shown in FIG. Figure 5 As shown) and the bottom abutment surface 1732 (as shown Figure 6 ). The top abutting surface 1731 is arranged at one end of the middle limiting portion 173 close to the cover plate 132, and the bottom abutting surface 1732 is arranged at one end of the middle limiting portion 173 close to the bottom plate 134. The top abutting surface 1731 is used to abut against the second end 1622 when the adjustment structure 16 is in the first position, and to limit the rotation angle of the second end 1622 when it rotates toward the bottom plate 134. The bottom abutting surface 1732 is used to abut against the first end 1621 when the adjustment structure 16 is in the second position, and to limit the rotation angle of the first end 1621 when it rotates toward the cover plate 132. The middle limiting portion 173 is provided with a plurality of clearance grooves 1734 on the surface opposite to the heating structure 20. The clearance grooves 1734 are used to provide an escape space when cooperating with the edge of the heating structure 20, so as to avoid collision between the middle limiting portion 173 and the elements on the heating structure 20. The middle limiting portion 173 located at the air inlet end 135 and the middle limiting portion 173 located at the air outlet end 136 are respectively placed at two opposite ends of the heating structure 20 arranged along the third direction Z, so that the heating structure 20 is located between the two.

[0077] At least one driving structure 18 is further provided in the heating cover body 1. The driving structure 18 is provided between two adjacent receiving cavities 13. In at least one embodiment of the present application, two driving structures 18 are provided in the heating cover body 1. Among them, one driving structure 18 is provided near the air inlet end 135, and the other driving structure 18 is provided near the air outlet end 136. The driving structure 18 is connected to the rotating shaft 161 in the adjustment structure 16, and is used to drive the rotating shaft 161 to rotate in the shaft hole 1312. In at least one embodiment of the present application, one driving structure 18 simultaneously drives multiple rotating shafts 161 in multiple receiving cavities 13 located at the air inlet end 135 to rotate synchronously; the other driving structure 18 simultaneously drives multiple rotating shafts 161 in multiple receiving cavities 13 located at the air outlet end 136 to rotate synchronously.

[0078] A plurality of heating structures 20 and a plurality of ventilation structures 30 are further provided in the heating cover 1. Each receiving cavity 13 receives at least one heating structure 20 and at least two ventilation structures 30. In at least one embodiment of the present application, the receiving cavity 13 located in the middle receives two heating structures 20 and four ventilation structures 30; and the two receiving cavities 13 located at the edges receive one heating structure 20 and two ventilation structures 30 respectively.

[0079] The heating structure 20 is contained in the containing cavity 13 and is located between the two middle limiting portions 173. In at least one embodiment of the present application, the heating structure 20 is located on the surface of the cover plate 132 opposite to the notch 1342. The heating structure 20 is used to heat the air in the containing cavity 300 so that the ambient temperature of the storage device 200 contained in the containing cavity 300 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. The heating structure 20 includes a heating portion 21, a plurality of mutually parallel heat dissipation portions 23, and a plurality of mutually parallel conduction portions 24. In at least one embodiment of the present application, the heating portion 21 is roughly in the shape of a flat plate, and the heating power of the heating portion 21 can be adjusted according to demand. The heating portion 21 is used to generate heat at a specified power under the control of the test platform 2. The heat dissipation portion 23 is used to conduct the heat of the heating portion 21 and the conduction portion 24 to the outside of the containing cavity 300 to reduce the ambient temperature of the storage device 200. The heat dissipation portion 23 is disposed between the heat generating portion 21 and the cover plate 132, and extends from the heat generating portion 21 toward the cover plate 132. The conduction portion 24 is used to conduct the heat generated by the heat generating portion 21 to the accommodating cavity 300 to increase the ambient temperature of the storage device 200. The conduction portion 24 is disposed between the heat generating portion 21 and the bottom plate 134, and extends from the heat generating portion 21 toward the bottom plate 134. When the storage device 200 is accommodated in the accommodating cavity 13, a storage device 200 is disposed between two adjacent conduction portions 24.

[0080] The ventilation structure 30 is used to drive the air flow in the receiving cavity 13. The two ventilation structures 30 located in the same receiving cavity 13 are symmetrically arranged at the two ends of the receiving cavity 13 and placed on the bottom plate 134. That is, one ventilation structure 30 is arranged at the air inlet end 135, and is located between the corresponding side wall 131 and the adjustment structure 16 arranged at the air inlet end 135 in the third direction Z; the other ventilation structure 30 is arranged at the air outlet end 136, and is located between the corresponding side wall 131 and the adjustment structure 16 arranged at the air outlet end 136 in the third direction Z. Further, at the air inlet end 135, the top limiting portion 171 and the bottom limiting portion 172 are arranged between the ventilation structure 30 and the middle limiting portion 173; at the air outlet end 136, the top limiting portion 171 and the bottom limiting portion 172 are arranged between the ventilation structure 30 and the middle limiting portion 173. The ventilation structure 30 at the air inlet end 135 is used to introduce air outside the receiving cavity 13 into the receiving cavity 13, and the ventilation structure 30 at the air outlet end 136 is used to discharge the air in the receiving cavity 13 to the outside of the receiving cavity 13. In at least one embodiment of the present application, the ventilation structure 30 is an axial flow fan. The rotation speed of the ventilation structure 30 can be adjusted according to demand.

[0081] In at least one embodiment of the present application, a temperature sensor (not shown) for sensing the ambient temperature in the receiving cavity 13 is further provided in the receiving cavity 13. The temperature sensor provided in the receiving cavity 13 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 and the ventilation structure 30 according to the sensed temperature.

[0082] The test platform 2 has a plurality of slots (not shown in the figure) 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 .

[0083] Specifically, the working principle of the testing device 100 is as follows:

[0084] When the storage device 200 is subjected to a high temperature test and the temperature in the accommodating cavity 300 is lower than the target temperature, the rotating plate 162 is in the first position under the drive of the driving structure 18, and the first end 1621 is received in the bottom limiting groove 1721, and the second end 1622 abuts against the top abutting surface 1731, so that the accommodating cavity 300 is in a sealed state to seal the storage device 200 in the accommodating cavity 300. At this time, the heating portion 21 in the heating structure 20 generates heat, and the conducting portion 24 conducts the heat generated by the heating portion 21 into the accommodating cavity 300 to increase the ambient temperature at the location where the storage device 200 is located. When the ambient temperature at the location where the storage device 200 is located exceeds the warning temperature, the heating portion 21 stops generating heat, and the heat dissipating portion 23 conducts the heat of the heating portion 21 and the conducting portion 24 to the outside of the accommodating cavity 300. At the same time, the two ventilation structures 30 work simultaneously, and the air outside the receiving cavity 13 is introduced into the receiving cavity 13 through the air inlet end 135, and flows along the first air flow path P1, so as to discharge the heat on the heat dissipation part 23 to the outside of the receiving cavity 13 by convection, so as to dissipate the heat of the heat dissipation part 23.

[0085] When the test is stopped or the normal temperature test is performed, the accommodating cavity 300 does not need to be sealed. Under the drive of the driving structure 18, the rotating plate 162 is in the second position, and the second end 1622 is accommodated in the top limit groove 1711, and the first end 1621 abuts against the bottom abutting surface 1732. At this time, the two ventilation structures 30 work simultaneously, and the air outside the accommodating cavity 13 is introduced into the accommodating cavity 13 by the air inlet end 135, and flows along the second air flow path P2 to discharge the heat on the heating part 21 and the conducting part 24 to the outside of the accommodating cavity 13, so as to quickly dissipate the heat of the accommodating cavity 300.

[0086] The above-mentioned heating cover 1 and the testing device 100 having the heating cover 1, by providing at least one receiving cavity 13 to cooperate with the testing platform 2 to contain the storage device 200 in a sealed manner, reduce the high temperature testing cost of the storage device 200. By providing an adjustment structure 16, a limiting structure 17 and a heating structure 20 in the receiving cavity 13 to cooperate to form a receiving cavity 300, the volume of the cavity used to accommodate the storage device 200 can be further reduced, and the heating speed of the ambient temperature at the location where the storage device 200 is located can be further increased. At the same time, the position of the adjustment structure 16 is changed by the driving structure 18, and the receiving cavity 300 is controlled to switch between a sealed state and an open state, so as to quickly adjust the internal temperature of the receiving cavity 300 under different requirements.

[0087] 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.
