Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and more specifically, to high and low temperature chambers. Background Technology

[0002] To test the performance of samples under high and low temperature environments, a high and low temperature chamber is provided in the related technology. This chamber uses a fan to blow air into it to regulate the temperature. However, the samples themselves generate a significant amount of heat during testing, which can easily affect the test results. Utility Model Content

[0003] This application provides a high and low temperature chamber to address the problem of how to reduce the impact of the heat generated by the sample itself inside the high and low temperature chamber on the test results.

[0004] An embodiment of this application provides a high and low temperature chamber, including a chamber body and a fan. The chamber body has a temperature-controlled compartment and an equipment compartment. The temperature-controlled compartment includes a first compartment for accommodating a target component and a second compartment communicating with the first compartment. The second compartment is disposed adjacent to the equipment compartment. The fan includes a housing, blades, and a drive component. The housing is disposed within the second compartment and has an air outlet communicating with the second compartment. The blades are disposed within the housing. The drive component is disposed within the equipment compartment, and the output shaft of the drive component extends into the second compartment and is drively connected to the blades.

[0005] The aforementioned high and low temperature chamber, by separately configuring a temperature control chamber and an equipment chamber within the chamber, and placing the drive unit and housing separately in the equipment chamber and temperature control chamber respectively, allows the size of the drive unit to be unrestricted by the limited space within the temperature control chamber. This enables the use of larger drive units, facilitating power expansion and improving the circulating airflow and convection effect around the target component. Thus, by improving the fan layout, the circulating airflow is increased, reducing the impact of the target component's own heat generation on the test results.

[0006] In one embodiment, the high and low temperature chamber further includes a first partition, which separates a first compartment and a second compartment. The first partition is provided with an air inlet channel, which connects the air outlet and the first compartment.

[0007] In one embodiment, the first partition includes air deflectors with air inlet channels.

[0008] In one embodiment, the side of the housing with the air outlet is connected to the first partition. A deflector louver covers the air outlet.

[0009] In one embodiment, the fan is a turbine fan, the casing is a vortex casing, and the air outlet is constructed in a trumpet shape.

[0010] In one embodiment, there are multiple fans distributed along a first direction, which intersects with the direction from the second chamber to the first chamber.

[0011] In one embodiment, there are two fans. The high and low temperature chamber also includes a second partition, which is disposed within the second compartment and divides the second compartment into two non-communicating chambers. The two fans are respectively disposed in the two chambers.

[0012] In one embodiment, the temperature control chamber further includes a third chamber and two reflux channels. The third chamber is located on the side of the first chamber away from the second chamber and is connected to the first chamber. The two reflux channels correspond to two chambers respectively and connect the third chamber to the corresponding chamber. The high and low temperature chamber also includes an evaporator and two heaters. The evaporator is located in the third chamber, and the two heaters are located in the two chambers respectively.

[0013] In one embodiment, the two return channels are located on both sides of the first compartment along a first direction.

[0014] In one embodiment, the equipment compartment includes a fourth compartment and a fifth compartment, with the fourth compartment adjacent to the first compartment and the fifth compartment adjacent to the second compartment. The high and low temperature chamber also includes testing equipment, located in the fourth compartment and used to test the target component. A drive unit is located in the fifth compartment.

[0025] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Example Figure 1 This is a perspective view of a high and low temperature chamber 100 according to an embodiment of this application; Figure 2 for Figure 1 A perspective view of the high and low temperature chamber 100 in the illustrated embodiment from another viewpoint; Figure 3 for Figure 1 A partial structural schematic diagram of the high and low temperature chamber 100 in the illustrated embodiment; Figure 4 for Figure 1 A partial structural schematic diagram of the high and low temperature chamber 100 in the embodiment shown.

[0027] See Figures 1 to 3 This embodiment provides a high and low temperature chamber 100, including a chamber body 10 and a fan 20. The chamber body 10 is provided with a temperature control chamber 11 and an equipment chamber 12. The temperature control chamber 11 includes a first chamber 111 for accommodating a target component 200, and a second chamber 112 communicating with the first chamber 111. The second chamber 112 is arranged adjacent to the equipment chamber 12. Figure 4 As shown, the fan 20 includes a housing 21, blades (not shown) and a drive component 23 (such as a motor). The housing 21 is disposed inside the second chamber 112 and has an air outlet 211 communicating with the second chamber 112. The blades are disposed inside the housing 21. The drive component 23 is disposed inside the equipment chamber 12. The output shaft of the drive component 23 extends into the second chamber 112 and is connected to the blades in a transmission manner.

[0028] The aforementioned high and low temperature chamber 100, by separately setting up a temperature control chamber 11 and an equipment chamber 12 within the chamber body 10, and placing the drive component 23 and the housing 21 within the equipment chamber 12 and the temperature control chamber 11 respectively, allows the volume of the drive component 23 to be unrestricted by the limited space within the temperature control chamber 11. This enables the use of a larger drive component 23, facilitating power expansion and improving the circulating air velocity and convection effect around the target component 200. Thus, by improving the layout of the fan 20, the circulating air velocity is increased, reducing the impact of the target component 200's own heat generation on the test results. This makes the high and low temperature chamber 100 suitable for target components 200 with high heat generation, improves the temperature uniformity within the temperature control chamber 11, accelerates the temperature response speed within the temperature control chamber 11, and enhances the accuracy and effectiveness of the test results. By placing the drive component 23 within the equipment chamber 12, the utilization rate of the space within the temperature control chamber 11 is also improved, thereby optimizing the layout within the temperature control chamber 11 and increasing the number of target components 200 that can be accommodated per unit volume. Optionally, the target component 200 can be a sample to be tested, such as a solid-state drive (SSD).

[0029] Figure 5 for Figure 1 Exploded view of the flow guide louver 31 and housing 21 in the illustrated embodiment.

[0030] In some embodiments, such as Figure 3 and Figure 5 As shown, the high and low temperature chamber 100 also includes a first partition 30, which separates the first chamber 111 and the second chamber 112. The first partition 30 is provided with an air inlet channel 30a, which connects the air outlet 211 and the first chamber 111. In this way, the air blown out of the air outlet 211 is directly introduced into the first chamber 111 through the air inlet channel 30a on the first partition 30. Since only the first partition 30 separates the air outlet 211 and the target component 200, no other airflow guiding structure is required, further increasing the wind speed around the target component 200.

[0031] In some embodiments, combined with Figure 3 and Figure 5As shown, the first partition 30 includes guide louvers 31, which have an air inlet channel 30a. Thus, by providing guide louvers 31, the airflow from the outlet 211 is guided, thereby facilitating control of the airflow direction entering the first chamber 111 through the air inlet channel 30a. For example, the airflow direction entering the first chamber 111 can be directed towards the direction from the second chamber 112 to the first chamber 111. In use, the direction from the second chamber 112 to the first chamber 111 can be horizontal. Optionally, the guide louvers 31 include two louvered plates 311, which are stacked on top of each other at the outlet 211, and the louvers on the two louvered plates 311 are perpendicular to each other.

[0032] In some embodiments, such as Figure 3 and Figure 5 As shown, the side of the housing 21 with the air outlet 211 is connected to the first partition 30, and the air guide louver 31 covers the air outlet 211. In this way, the air blown out of the air outlet 211 directly enters the air inlet channel 30a, shortens the distance between the air outlet 211 and the target component 200, and further increases the wind speed around the target component 200.

[0033] In some embodiments, such as Figure 3 and Figure 5 As shown, the fan 20 is a turbine fan, the casing 21 is a vortex casing, and the air outlet 211 is constructed in a trumpet shape to increase the air outlet area of ​​the air outlet 211, which is beneficial to increasing the number of target components 200 that can be arranged per unit volume.

[0034] In some embodiments, such as Figure 3 As shown, there are multiple fans 20, which are distributed along a first direction Z, which intersects the direction from the second chamber 112 to the first chamber 111. Thus, by providing multiple fans 20, it is beneficial to increase the number of target components 200 that can be placed inside the temperature control chamber and further improve the convection effect around the target components 200.

[0035] In some embodiments, such as Figure 3 As shown, there are two fans 20. The high and low temperature chamber 100 also includes a second partition 40, which is located inside the second chamber 112 and divides the second chamber 112 into two non-communicating chambers 1121. The two fans 20 are respectively located in the two chambers 1121. In this way, by setting the second partition 40, the air blown by the two fans 20 is prevented from colliding and causing the air velocity in the middle part of the two fans 20 to drop rapidly.

[0036] In some embodiments, such as Figure 3As shown, the temperature-controlled chamber 11 also includes a third chamber 113 and two return channels 114. The third chamber 113 is located on the side of the first chamber 111 away from the second chamber 112 and is connected to the first chamber 111. The two return channels 114 correspond to the two chambers 1121 respectively, and the return channels 114 connect the third chamber 113 and the corresponding chambers 1121. The high and low temperature chamber 100 also includes an evaporator 50 and two heaters 60. The evaporator 50 is located in the third chamber 113, and the two heaters 60 are located in the two chambers 1121 respectively. In this way, after the air from the first chamber 111 flows into the third chamber 113, the cooling energy of the evaporator 50 is effectively mixed with the heating energy of the heaters 60 before being output to the first chamber 111 by the fan 20, so as to regulate the temperature inside the temperature-controlled chamber 11. It should be noted that... Figure 3 The arrows in the diagram indicate the direction of airflow within the temperature-controlled chamber 11. The airflow output from the air outlet 211 passes through the first chamber 111 and enters the third chamber 113. It then returns to the second chamber 112 via the return channel 114, is drawn in by the fan 20, and is output from the air outlet 211, forming a cycle.

[0037] In some embodiments, such as Figure 3 As shown, the two return channels 114 are located on both sides of the first chamber 111 along the first direction Z, so as to make the layout inside the temperature control chamber 11 reasonable. It should be noted that verticality within 5° or the angle between two adjacent directions between 85° and 95° can be considered vertical.

[0038] In some embodiments, such as Figure 4 As shown, the equipment compartment 12 includes a fourth compartment 121 and a fifth compartment 122, combined with Figure 3 As shown, the fourth compartment 121 is arranged adjacent to the first compartment 111, and the fifth compartment 122 is arranged adjacent to the second compartment 112. The high and low temperature chamber 100 also includes a testing device 90, which is located in the fourth compartment 121 and is used to test the target component 200. The drive unit 23 is located in the fifth compartment 122 to make the layout of the equipment compartment 12 more reasonable. Optionally, the high and low temperature chamber 100 also includes a condenser 70 and a compressor 80, which are respectively located in the fifth compartment 122.

[0039] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
