Description

Technical Field

[0001] The invention relates to the technical field of refrigeration sheet detection, in particular to a constant temperature platform device for detecting the resistance of a semiconductor refrigeration sheet. Background Art

[0002] In the Chinese patent with the patent announcement number CN212057887U, a small constant temperature device for teaching instruments based on a semiconductor refrigeration sheet group is disclosed, including a block-shaped refrigeration heat-conducting interlayer, the upper and lower surfaces of the refrigeration heat-conducting interlayer are each provided with a constant temperature unit, and the constant temperature unit is detachably fixedly connected to the refrigeration heat-conducting interlayer; a heat-conducting medium channel is formed inside the refrigeration heat-conducting interlayer, and the heat-conducting medium channel is provided with a liquid inlet and a liquid outlet; each of the constant temperature units includes an electric fan, a refrigeration heat sink and a semiconductor refrigeration sheet, one surface of the semiconductor refrigeration sheet is bonded to the surface of the refrigeration heat-conducting interlayer, and the other surface is bonded to the refrigeration heat sink; all semiconductor refrigeration sheets are individually connected to the external circuit through electrode wires. The device has both heating and rapid heat dissipation functions, which meets the temperature regulation of the teaching instrument, thereby enabling the teaching instrument to better complete the teaching of students.

[0003] However, the following defects still exist in the specific use of the comparative documents:

[0004] 1. Although the temperature of the device can be controlled to a certain extent in the comparative document, the surface bonding between the cooling plate and the cooling thermal interlayer cannot be stable. At the same time, when the cooling plate radiator is working, the rotation of the fan inside the radiator will cause the cooling plate to vibrate during operation, which will cause the cooling plate to be unable to fit with the surface of the cooling thermal interlayer in real time, making it impossible for the device to truly reflect the temperature distribution of the cooling plate under working conditions.

[0005] 2. In addition, when the existing refrigeration plates are dissipating heat, the existing refrigeration plates usually directly adjust the cooling power of the equipment during heat dissipation control and detection, and are unable to adjust the opening and closing diameters of the heat dissipation holes in the refrigeration plates from the source. Since the diameters of the heat dissipation holes cannot be adjusted according to actual needs, not only will the optimization of the heat dissipation efficiency be limited, but also under different working conditions, the heat generated by the refrigeration plates is different, and the fixed diameter may not be able to adapt to the changing heat dissipation requirements, resulting in the inability to dissipate heat in time, causing the refrigeration plate to overheat, affecting its working performance and stability.

[0033] The present invention is further described in detail below based on the accompanying drawings and embodiments;

[0034] Example

[0035] Please refer to Figures 1 to 7 As shown:

[0036] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a constant temperature platform device for detecting the resistance of a semiconductor refrigeration sheet, including a detection platform 1, a partition plate 12 is fixedly connected to the middle of the detection platform 1, a temperature sensor 11 is arranged on the upper surface of the detection platform 1, a heat exchange device 13 is arranged below the partition plate 12, and the heat exchange device 13 is installed at the bottom of the detection platform 1, and also includes a multi-dimensional stability detection mechanism 2, which is arranged on the upper surface of the partition plate 12;

[0037] The multi-dimensional stability detection mechanism 2 is used for installation and positioning during refrigeration plate detection;

[0038] The multi-dimensional stability detection mechanism 2 includes a multifunctional pressing column 21, the outer surface of the multifunctional pressing column 21 is slidably connected to the upper surface of the detection platform 1, the temperature sensor 11 is installed in the middle of the upper surface of the multifunctional pressing column 21, the bottom end of the multifunctional pressing column 21 is fixedly connected to a buffer spring 22, the end of the buffer spring 22 away from the multifunctional pressing column 21 is fixedly connected to the partition plate 12, and the two sides of the lower surface of the multifunctional pressing column 21 are rotatably connected to push plates 23;

[0039] The push plate 23 is rotatably connected to one end away from the multifunctional pressing column 21 with a T-shaped slide plate 24, the bottom of the T-shaped slide plate 24 is slidably connected to the partition plate 12, and both ends of the T-shaped slide plate 24 away from the buffer spring 22 are rotatably connected to auxiliary blocks 25, and the auxiliary block 25 is rotatably connected to one end away from the T-shaped slide plate 24 with a pry plate 26;

[0040] The middle part of the pry plate 26 is rotatably connected to the detection table 1, the auxiliary block 25 is symmetrically rotatably connected to the two ends of the pry plate 26, and the upper end of the pry plate 26, the auxiliary block 25 away from the pry plate 26, is rotatably connected to the clamping plate 27, and the clamping plate 27 is slidably connected in the detection table 1;

[0041] A card slot 28 is provided on the outer surface of the multifunctional pressing column 21, and a card plate 29 is engaged in the card slot 28. The upper surface of the card plate 29 is slidably connected to the detection platform 1. An adjustment rod is fixedly connected to the side of the card plate 29 away from the card slot 28, and a spring is sleeved in the adjustment rod. One end of the spring is fixedly connected to the card plate 29, and the other end of the spring is fixedly connected to the detection platform 1.

[0042] Wherein: the auxiliary block 25 to the clamping plate 27 are symmetrically arranged on both sides of the push plate 23.

[0043] Although the temperature of the device can be controlled to a certain extent in the comparative document, the surface fitting between the cooling plate and the cooling heat conductive interlayer cannot be achieved firmly. At the same time, when the cooling plate radiator is working, the rotation of the fan inside the radiator will cause the cooling plate to vibrate during operation, thereby causing the cooling plate to be unable to fit with the surface of the cooling heat conductive interlayer in real time, thereby making it impossible for the device to truly reflect the temperature distribution of the cooling plate under working conditions. Through the implementation of this embodiment, it can be adapted to different sizes of cooling plates through settings. By placing the cooling plate on the multifunctional pressing column 21 and gently pressing the cooling plate, the cooling plate can be firmly fixed on the test bench 1 for testing. This can not only ensure the close fit between the cooling plate and the arc-shaped heat exchange hole 36, reduce the thermal resistance caused by poor contact, thereby improving the efficiency of heat transfer, and the efficient heat transfer through the heat exchange device 13 enables the cooling plate to more accurately reach and maintain the set constant temperature state, thereby improving the accuracy of the detection.

[0044] For further examples, please refer to Figures 1 to 7 As shown:

[0045] A temperature control mechanism 3 is provided in the middle of the test bench 1, and the temperature control mechanism 3 is used to control the constant temperature of the refrigeration plate;

[0046] The temperature control mechanism 3 includes a threaded adjustment rod 31, an indicator needle 32 is rotatably connected to the non-threaded portion of the outer surface of the threaded adjustment rod 31, and a scale plate 33 is slidably connected to the end of the indicator needle 32 away from the threaded adjustment rod 31, and the scale plate 33 is fixedly connected to the detection platform 1;

[0047] The end of the threaded adjustment rod 31 away from the indicator needle 32 is rotatably connected to a bidirectional sliding tooth plate 34, and the tooth surface of the bidirectional sliding tooth plate 34 is meshed with a multifunctional ventilation plate 35. The multifunctional ventilation plates 35 are symmetrically arranged on both sides of the bidirectional sliding tooth plate 34. The upper surface of the multifunctional ventilation plate 35 is rotatably connected to the detection platform 1. The upper surface of the detection platform 1 is provided with an arc-shaped heat exchange hole 36, and the size of the arc-shaped heat exchange hole 36 matches that of the multifunctional ventilation plate 35.

[0048] The multifunctional ventilation plates 35 are symmetrically arranged on both sides of the bidirectional sliding gear plate 34 , and the arc-shaped heat exchange holes 36 match the size of the multifunctional ventilation plates 35 .

[0049] In addition, when the existing refrigeration plate is dissipating heat, the existing refrigeration plate usually directly adjusts the cooling power of the equipment during heat dissipation control and detection, and cannot adjust the opening and closing diameter of the heat dissipation holes in the refrigeration plate from the source. Since the diameter of the heat dissipation holes cannot be adjusted according to actual needs, not only will the optimization of the heat dissipation efficiency be limited, but also under different working conditions, the heat generated by the refrigeration plate is different, and the fixed diameter may not be able to adapt to the changing heat dissipation needs, resulting in the inability to dissipate heat in time, causing the refrigeration plate to overheat, affecting its working performance and stability. Through the implementation of this embodiment, the opening and closing degree can be adjusted according to the actual working conditions through the dynamic adjustment of the multifunctional ventilation plate 35 and the arc-shaped heat exchange hole 36, and the air circulation can be optimized, so that the heat generated by the refrigeration plate can be more effectively dissipated under high temperature or high load conditions, so that more effective heat dissipation management can help reduce the operating temperature of the refrigeration plate and its surrounding components, reduce thermal stress, thermal fatigue and thermal expansion caused by high temperature and other problems, not only can the semiconductor refrigeration plate reach a constant temperature during resistance detection, but also the accuracy of the semiconductor refrigeration plate detection results can be guaranteed.

[0050] Everything in the above example works like this:

[0051] In the initial state: the device is not running, the semiconductor cooling sheet is not placed on the test bench 1, and the indicator needle 32 is not compressed.

[0052] The following is the working process of the installation and positioning of the multi-dimensional stability detection mechanism 2 for refrigeration plate detection:

[0053] Before the test, the operator first manually places the semiconductor refrigeration sheet on the upper surface of the test bench 1 near the multifunctional pressing column 21. After the refrigeration sheet is fitted with the multifunctional pressing column 21, the operator begins to slowly press the refrigeration sheet downward. At this time, as the refrigeration sheet is squeezed, the multifunctional pressing column 21 begins to slide downward along the test bench 1. At this time, since the temperature sensor 11 is installed in the middle of the upper surface of the multifunctional pressing column 21, a buffer spring 22 is fixedly connected to the bottom end of the multifunctional pressing column 21. The buffer spring 22 is fixedly connected to the partition plate 12 at one end away from the multifunctional pressing column 21. The multifunctional pressing column 21 is pressed downward. Push plates 23 are rotatably connected to both sides of the lower surface of the pressure column 21, so the downward movement of the multifunctional pressing column 21 will drive the multifunctional pressing column 21 to be compressed. Furthermore, because the push plate 23 is rotatably connected to one end away from the multifunctional pressing column 21 and a T-shaped slide plate 24 is slidably connected to the bottom of the T-shaped slide plate 24 on the partition plate 12, the downward sliding of the multifunctional pressing column 21 will drive the push plates 23 on both sides to start driving the T-shaped slide plate 24 to slide to the side away from the buffer spring 22. Because the T-shaped slide plate 24 slides symmetrically on both sides of the partition plate 12 close to the multifunctional pressing column 21, and has the same function, it is only used for Figure 5The group of numbered parts shown in the figure is described. At this time, the multifunctional pressing column 21 slides downward, which drives the buffer spring 22 to drive the T-shaped slide plate 24 to slide to the left. At the same time, because the T-shaped slide plate 24 is away from the buffer spring 22, both ends are rotatably connected to the auxiliary blocks 25, and the auxiliary block 25 is rotatably connected to the pry plate 26 at one end away from the T-shaped slide plate 24. The auxiliary block 25 at the upper end of the pry plate 26 is rotatably connected to the pry plate 26. The pry plate 27 is slidably connected in the test bench 1. At this time, it can be known from the principle of lever that the auxiliary block 25 is driven by the pry plate 26 when the T-shaped slide plate 24 is pushed to the left, and the pry plate 26 drives the auxiliary block 25 to start clamping the refrigeration sheet along the upper surface of the test bench 1.

[0054] At this time, since the outer surface of the multifunctional pressing column 21 is provided with a slot 28, a card plate 29 is engaged in the slot 28, and the upper surface of the card plate 29 is slidably connected to the detection platform 1, and the card plate 29 is fixedly connected to the side away from the slot 28. An adjusting rod, and a spring is sleeved in the adjusting rod, one end of the spring is fixedly connected to the card plate 29, and the other end of the spring is fixedly connected to the detection platform 1, so when the multifunctional pressing column 21 slides downward, the slot 28 and the card plate 29 will be engaged with each other under the elastic action of the spring. Since the slot 28 is provided as an inclined slot, due to the oblique design of the inclined slot, when the axial force and the friction force are applied, this design enables the card plate 29 to interact with the slot 28 when it is engaged with the slot 28 so that the slot 28 It can only move downward, and when the slot 28 moves upward, it will be engaged by the non-inclined part of the card plate 29, so that the slot 28 can only move downward in one direction, so that the slot 28 can realize the mutual locking function with the card plate 29 while moving downward, so as to ensure that the refrigeration plate can be stably fixed on the upper surface of the arc-shaped heat exchange hole 36 through the clamping plate 27 during the inspection, and when the refrigeration plate inspection is completed, the operator only needs to manually pull the card plate 29 to the right along the inspection table 1 close to the semi-arc plate of the outer surface of the inspection table 1. At this time, the card plate 29 begins to no longer engage with the slot 28, and the elastic action of the buffer spring 22 will drive the multi-functional pressing column 21 to drive the refrigeration plate on the upper surface of the multi-functional pressing column 21 to pop up, thereby completing the initial dissociation of the refrigeration plate.

[0055] Since different types of refrigeration plates may differ in size and shape, refrigeration plates of different sizes can be adjusted and fixed by pressing the multifunctional pressing column 21, which can not only flexibly adapt to the changes in the initial fixation of refrigeration plates of different sizes, but also achieve stable clamping of multiple refrigeration plates. This design makes the detection equipment no longer limited to specific types of refrigeration plates, thereby enhancing the versatility and flexibility of the equipment. Compared with the prior art for refrigeration plate detection, the card slot 28 and the card plate 29 are engaged, which can not only flexibly adapt to these changes, but also achieve stable clamping of multiple refrigeration plates. This design makes the detection equipment no longer limited to specific types of refrigeration plates, thereby enhancing the versatility and flexibility of the equipment. Compared with the prior art of clamping refrigeration plates of different sizes, which simply places the refrigeration plate on the table, the refrigeration plate may not contact the bottom heat exchange plate when clamping the refrigeration plate, resulting in low heat exchange efficiency. However, according to the arrangement of the present invention, the operator can not only clamp and fix the refrigeration plate by pressing the refrigeration plate, but also make the bottom of the refrigeration plate fully contact with the arc-shaped heat exchange hole 36 by pressing the refrigeration plate. The close fit between the refrigeration plate and the surface of the arc-shaped heat exchange hole 36 is not only conducive to improving the heat conduction efficiency, but also creates good heat dissipation conditions. This design helps the refrigeration plate to maintain a stable temperature state during operation, thereby providing a strong guarantee for achieving high-precision detection.

[0056] Please refer to the above working process Figures 1 to 7 .

[0057] The following is the working process of the temperature control mechanism 3 for controlling the constant temperature of the refrigeration plate:

[0058] When in use, as mentioned above, when testing, it is necessary to control the internal temperature of the refrigeration plate to be constant. When the temperature at the bottom of the refrigeration plate rises because the refrigeration plate cannot absorb enough heat from the refrigerant, the operator only needs to Figure 6 and Figure 7As shown, the threaded adjustment rod 31 is manually rotated clockwise, because the non-threaded portion of the outer surface of the threaded adjustment rod 31 is rotatably connected to an indicator needle 32, and the indicator needle 32 is slidably connected to a scale plate 33 at one end away from the threaded adjustment rod 31, and the scale plate 33 is fixedly connected to the test bench 1. At this time, under the action of the threaded adjustment rod 31 and the test bench 1, the threaded adjustment rod 31 is rotatably connected to the bidirectional sliding tooth plate 34, so when the threaded adjustment rod 31 is rotated, the indicator needle 32 will start to slide to the left on the scale plate 33 synchronously, and at the same time, the bidirectional sliding tooth plate 34 will also start to slide to the left through the threaded adjustment rod 31. Slide to the left, at this time, because the tooth surface of the two-way sliding tooth plate 34 is meshed with the multifunctional ventilation plate 35, the multifunctional ventilation plate 35 is symmetrically arranged on both sides of the two-way sliding tooth plate 34, and the upper surface of the multifunctional ventilation plate 35 is rotatably connected to the detection platform 1. Because the upper surface of the detection platform 1 is provided with an arc-shaped heat exchange hole 36, the arc-shaped heat exchange hole 36 matches the size of the multifunctional ventilation plate 35, so when the two-way sliding tooth plate 34 slides to the left, it will drive the multifunctional ventilation plate 35 and the arc-shaped heat exchange hole 36 to separate from each other. At this time, because the opening and closing size of the adjustment can be directly observed through the scale plate 33 when adjusting the threaded adjustment rod 31, it can be further The opening and closing angles can be monitored and adjusted step by step. The opening and closing degrees can be adjusted according to the actual working conditions to optimize the air circulation, so that the heat generated by the refrigeration plate can be more effectively dissipated under high temperature or high load conditions, so that more effective heat dissipation management can help reduce the operating temperature of the refrigeration plate and its surrounding components, and reduce problems such as thermal stress, thermal fatigue and thermal expansion caused by high temperature. The opening and closing degrees can be adjusted according to the actual working conditions through dynamic adjustment of the multifunctional vent plate 35 and the arc-shaped heat exchange hole 36. By optimizing the air circulation, when the multifunctional vent plate 35 and the arc-shaped heat exchange hole 36 are opened to each other, the hot air inside the equipment will be discharged due to the temperature difference. It naturally rises and is discharged through the arc-shaped heat exchange hole 36. At the same time, the external air, driven by the pressure difference or auxiliary equipment such as fans, will enter the interior of the device along the arc-shaped heat exchange hole 36 to fill the space left by the hot air. This continuous air flow not only helps to reduce the temperature inside the device, but also effectively prevents heat from accumulating inside the device, thereby achieving the effect of optimizing air circulation, and can more effectively dissipate the heat generated by the cooling plate under high temperature or high load conditions, which can not only increase the temperature of the semiconductor cooling plate to remain constant during resistance detection, but also ensure the accuracy of the semiconductor cooling plate detection results.
