Description
Technical Field
[0001] This utility model belongs to the field of thermal storage material performance testing technology, and relates to the performance testing technology of inner lining thermal coating, specifically a performance monitoring and testing device for inner lining thermal coating. Background Technology
[0002] Referring to patent document application number 2024202261804, a temperature control system for controlling radar temperature is disclosed. This patent document relates to a heat storage device, which includes heating wires and a thermal coating. Further research revealed that this thermal coating can be applied to the inner lining panel of a vehicle to form an inner lining thermal coating for temperature regulation of the vehicle's interior space. The structure of the inner lining thermal coating is described below. Figure 1 The inner thermal lining coating comprises a base layer, a surface layer, and a cavity formed by the base layer and the surface layer. A heat-storing coating and heating wires are installed within the cavity. The principle behind this inner thermal lining coating's temperature regulation of the vehicle's interior space is as follows: When the interior temperature is low, the heating wires begin heating. When the temperature reaches the phase change temperature of the heat-storing coating, the coating undergoes a phase change to store heat, delaying further temperature increases until the interior temperature reaches its upper limit, at which point heating stops. When the interior temperature is below the phase change temperature of the heat-storing coating, it releases heat, providing insulation. Therefore, using this inner thermal lining coating can absorb the heat dissipated during heating and release it at low temperatures for insulation, thus saving energy.
[0003] Based on the above analysis, preliminary research shows that the thermal coating of the inner lining can be used for temperature regulation on the inner lining panels of vehicles. However, there is currently a lack of technical means to monitor and test the heat storage performance of the thermal coating, making it impossible to verify the uniformity of the temperature distribution when the thermal coating is working, which affects the further promotion and application of the thermal coating.

The test sample 3 is located on the bottom wall of the inner cavity of the test frame. The test space 2, formed by the test frame, simulates the internal space of a vehicle, providing a testing environment for the test space 2. See also Figure 4Test sample 3 includes a substrate, an inner thermal coating 301, a heat insulation pad 302, and a conductive sheet 303. The inner thermal coating 301 and the heat insulation pad 302 are both coated on the substrate. There are multiple inner thermal coatings 301 and heat insulation pads 302, which are distributed alternately from top to bottom on the substrate. Multiple inner thermal coatings 301 are connected to the conductive sheet 303, and the heating wires on the inner thermal coatings 301 are powered through the conductive sheet 303. Each inner thermal coating 301 and each heat insulation pad 302 is provided with a detection point 304. The heating power supply unit is connected to the conductive sheet 303 and is used to power the conductive sheet 303. The detection points 304 on the inner thermal coating 301 and the heat insulation pad 302 are both connected to the monitoring and testing unit. This utility model provides a technical means for monitoring and testing the heat storage performance of the inner lining thermal coating 301, thereby enabling the monitoring and testing of the uniformity of the temperature distribution of the inner lining thermal coating 301 during operation.
[0022] In this invention, the substrate can be a metal plate, cloth, or other structure that can provide a planar surface. In a preferred embodiment of this invention, the substrate is cloth, which is fixed to the bottom wall of the inner cavity of the test frame by adhesive.
[0023] In this invention, the number of inner heat-coating layers 301 and the number of heat-insulating pads 302 can be 2, 3, 4, or even more. This invention does not specifically limit the number of inner heat-coating layers 301 and the number of heat-insulating pads 302. However, in a preferred embodiment of this invention, the number of inner heat-coating layers 301 is 5, and the number of heat-insulating pads 302 is 4. The heat-insulating pads 302 separate adjacent inner heat-coating layers 301, preventing mutual interference between adjacent inner heat-coating layers 301.
[0024] See Figure 4 In a preferred embodiment of the present invention, the conductive sheet 303 includes a positive conductive sheet and a negative conductive sheet, which are respectively connected to the two ends of the inner heat-coating 301. Both the positive and negative conductive sheets are connected to the heating wires on all the inner heat-coating 301. The positive conductive sheet is connected to the positive electrode of the heating power supply unit, and the negative conductive sheet is connected to the negative electrode of the heating power supply unit.
[0025] In a preferred embodiment of this utility model, the detection points 304 on the inner heat coating 301 and the heat insulation pad 302 are diagonally distributed on the test sample 3, so that point detection can be carried out at different locations on different inner heat coatings 301, thereby improving the accuracy of the temperature distribution uniformity test on the inner heat coating 301.
[0026] See Figure 3 and Figure 5In this invention, the monitoring and testing unit includes a display screen 5, a temperature control module 6, and temperature sensors. The number of temperature sensors is the sum of the number of detection points 304 on the inner lining thermal coating 301 and the number of detection points 304 on the insulation pad 302. Each temperature sensor includes a temperature sensor head 12 and a temperature sensor probe 13. The temperature sensor head 12 is connected to the corresponding detection point 304 via the temperature sensor probe 13 to detect the real-time temperature of the corresponding detection point 304 and send the data to the corresponding temperature sensor head 12 for display. The uniformity of temperature distribution at different locations on different parts of the inner lining thermal coating 301 is displayed based on the temperatures displayed on each temperature sensor head 12, facilitating data monitoring and recording by testing personnel. All temperature sensor heads 12 are connected to the temperature control module 6, which is connected to the display screen 5. The temperature control module 6 controls the temperature on each inner lining thermal coating 301, and the display screen 5 displays the control results.
[0027] In this invention, both the temperature control module 6 and the temperature sensor are commercially available products. The temperature control module 6 is model TEY4-RC18, and the temperature sensor is model LM35. The TEY4-RC18 temperature control module 6 is a four-channel module, capable of independently controlling each of the four channels, including setting different temperature thresholds and connecting different types of temperature sensors. Since this application sets multiple detection points 304, each detection point 304 requires a corresponding temperature sensor. Therefore, this application can use three temperature control modules 6; alternatively, one temperature control module 6 can be used to monitor and test different detection points 304 in batches.
[0028] In this invention, the monitoring and testing unit also includes a first battery 10 and a control switch group 9. The first battery 10 is connected to the temperature control module 6 and the temperature sensor respectively through the control switch group 9. The first battery 10 supplies power to the temperature control module 6 and the temperature sensor respectively through the control switch group 9, and then supplies power to the display screen 5 through the temperature control module 6.
[0029] In this utility model, the heating power supply unit includes a potentiometer 8 and a second battery 11. The second battery 11 is connected to a control switch group 9, and the control switch group 9 is connected to a conductive sheet 303 through the potentiometer 8. That is, the second battery 11 is connected to the conductive sheet 303 in sequence through the control switch group 9 and the potentiometer 8. The potentiometer 8 is connected to a temperature control module 6. The temperature control module 6 controls the potentiometer 8, thereby adjusting the current provided by the second battery 11 to the conductive sheet 303 to achieve temperature control of the inner lining heat coating 301.
[0030] Specifically, the control switch group 9 includes a first control switch and a second control switch. The first control switch is connected to the first battery 10, the temperature control module 6 and the temperature sensor respectively, and is used to control the on / off of the circuit between the first battery 10 and the temperature control module 6 and the temperature sensor. The second control switch is connected to the second battery 11 and the potentiometer 8 respectively, and is used to control the on / off of the circuit between the second battery 11 and the potentiometer 8.
[0031] In this invention, the performance monitoring and testing device for the inner lining thermal coating also includes a power socket 7, which is used to connect to the first battery 10 and the second battery 11 and to charge the first battery 10 and the second battery 11. When it is necessary to charge the first battery 10 and the second battery 11, the first battery 10 and the second battery 11 are connected to the power socket 7.
[0032] In this invention, the performance monitoring and testing device for the inner thermal coating also includes an electrical control cabinet 4. The electrical control cabinet 4 includes a cabinet body 401 and a cabinet door 402, which together form an electrical control cavity. The temperature sensor meter 12 and the display screen 5 are both mounted on the cabinet door 402 for easy viewing by testing personnel. The temperature control module 6, power socket 7, control switch group 9, first battery 10, potentiometer 8, and second battery 11 are all located within the electrical control cavity. In a preferred embodiment of this invention, due to the large weight of the first and second batteries 10 and 11, they are positioned at the bottom of the electrical control cavity, the control switch group 9 is positioned in the middle, and the temperature control module 6 and power socket 7 are positioned at the top. The potentiometer 8 can be positioned as needed within the electrical control cabinet 4, near the test space 2.
[0033] In this utility model, the performance monitoring and testing device for the inner lining thermal coating also includes a support frame 1. The test sample 3 and the electrical control cabinet 4 are both fixed on the support frame 1, and the test sample 3, the test frame and the electrical control cabinet 4 are fixed by the support frame 1.
[0034] As a preferred embodiment of the present invention, the performance monitoring and testing device for the inner lining thermal coating of the present invention also includes an alarm unit. The alarm unit is connected to the temperature control module 6. When the temperature control module 6 determines that the temperature of the inner lining thermal coating 301 is too high or abnormal, it sends an alarm signal to the alarm unit. The alarm unit issues an alarm based on the alarm signal to remind the test personnel.
[0035] This utility model discloses a performance monitoring and testing device for an inner thermal coating. Its working principle is as follows: a second battery 11 supplies power to a conductive sheet 303, which in turn supplies power to the heating wires on the inner thermal coating 301, thereby heating the test space 2. During the heating process, once the temperature inside the test space 2 reaches the phase change temperature of the inner thermal coating 301, the inner thermal coating 301 begins to undergo phase change and store heat, delaying further temperature increases in the test space 2 until the temperature inside the test space 2 reaches the upper temperature limit (generally set to 26℃). At this point, the heating wires are de-energized, and heating stops. When the temperature inside the test space 2 is lower than the phase change temperature of the inner thermal coating 301, the inner thermal coating 301 begins to release heat, providing a heat preservation effect, until the temperature inside the test space 2 falls below the lower temperature limit (generally set to 5℃). Then, the second battery 11 supplies power to the conductive sheet 303, heating the test space 2. This process is repeated continuously to achieve temperature regulation and control within the test space 2.
[0036] During the heat storage and release process of the inner lining thermal coating 301, the temperature of each detection point 304 is detected in real time by the temperature sensor probe 13 and sent to the corresponding temperature sensor head 12 for display. The uniformity of temperature distribution in different parts of the inner lining thermal coating 301 is judged based on the temperature displayed on each temperature sensor head 12. For example, if the difference in temperature values displayed by each temperature sensor head 12 does not exceed 0.5℃, the temperature distribution in different parts of the inner lining thermal coating 301 is considered uniform; otherwise, the temperature distribution in different parts of the inner lining thermal coating 301 is considered uneven. At the same time, the temperature control module 6 controls the potentiometer 8, thereby adjusting the current provided by the second battery 11 to the conductive sheet 303 to control the temperature of each inner lining thermal coating 301. The control results are displayed on the display screen 5, for example, the magnitude of the current, thus monitoring and testing the uniformity of temperature distribution of the inner lining thermal coating 301 during operation.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
