[0031] An experimental box provided by the utility model for exploring factors affecting heat absorption and heat dissipation is now described.
[0032] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an experimental box for exploring factors affecting heat absorption and heat dissipation, including a box body 1, a bulb 2, a cross scale 3, a test box 4, a temperature sensing module 5 and a display module 6; operation ports 11 are provided on four sides of the box body 1; the bulb 2 is arranged in the middle position of the box body 1; the cross scale 3 is arranged on the inner wall of the box body 1, and the bulb 2 is located above the center of the cross scale 3; at least two test boxes 4 are arranged, and the test boxes 4 are placed on the cross scale 3 and face the bulb 2; the temperature sensing modules 5 are the same in number as the test boxes 4 and are arranged in the test boxes 4 one by one; the display module 6 is arranged on the box body 1 and connected to the corresponding temperature sensing module 5, and the display module 6 is used to display the sensed temperature value of the temperature sensing module 5 in real time.
[0033] Students can choose test boxes 4 of the same color or different colors of black and white according to the influencing factors they need to explore, and place them at the same distance from the light bulb 2 according to the scale on the cross scale 3, and then choose the same side or different sides, the same inclination angle or different inclination angles of the test box 4 to face the light bulb 2. The operation is convenient and the experimental effect is good.
[0034] Specifically, in Figure 1In the figure, the test box 4 at the rear is black, and the other three test boxes 4 are white; the experimental data of the rear test box 4 and the right test box 4 can be used to explore the factors affecting color; the experimental data of the left test box 4 and the right test box 4 can be used to explore the factors affecting the tilt angle; the experimental data of the front test box 4 and the right test box 4 can be used to explore the factors affecting area, thereby realizing the exploration of three influencing factors at the same time, and two of the test boxes 4 can also be used to explore a single influencing factor.
[0035] The present embodiment provides an experimental box for exploring factors affecting heat absorption and heat dissipation. Compared with the prior art, by orienting the test box 4 with different sides facing the bulb 2, with different tilt angles facing the bulb 2, or using black and white test boxes 4 with the same side facing the bulb 2, the area factor, angle factor and color factor can be tested simultaneously or separately, so that the same set of teaching aids can be used to explore which factors are related to the amount of heat absorbed by the solar water heater, and whether black objects can accelerate heat transfer. This makes it more convenient and efficient for students to operate, thereby achieving the effect of an efficient classroom, while at the same time cultivating students' scientific thinking and inquiry practice ability in a more in-depth manner.
[0036] like Figure 3 to Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0037] The outer surface of the bulb 2 is divided into two test areas by its middle part. The two test areas of the bulb 2 are respectively provided with a black coating layer 21 and a white coating layer 22. Two thermometers 7 are provided on the box body 1 and are located on both sides of the bulb 2. The sensing ends of the two thermometers 7 are facing the corresponding black coating layer 21 and the white coating layer 22.
[0038] By using a light bulb 2 coated with a black layer 21 and a white layer 22, when heat is conducted outward from the filament inside the light bulb 2 through the black layer 21 or the white layer 22, the temperature sensed by the two thermometers 7 gradually increases, and the experiment that black objects can accelerate heat transfer can be more intuitively explored.
[0039] like Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0040] The top of the box body 1 is provided with two insertion holes 12 for the thermometer 7 to pass through. The thermometer 7 is provided with a positioning block 71 mounted on the insertion hole 12 . When the positioning block 71 is mounted on the insertion hole 12 , the sensing end of the thermometer 7 faces the bulb 2 .
[0041] Furthermore, the socket 12 is a bar-shaped hole, and the two sockets 12 are symmetrically arranged with respect to the light bulb 2 . The length directions of the two sockets 12 are consistent and both face the light bulb 2 .
[0042] Furthermore, a scale bar is provided on the top of the box body 1 on one side of the jack 12 , and the length direction of the scale bar is consistent with the length direction of the jack 12 .
[0043] Students can adjust the distance between the thermometer 7 and the bulb 2 according to the scale bar through the jack 12, which better improves the operability of the experimental box. The setting of the positioning block 71 can limit the height position of the thermometer 7, making it more convenient to align the sensing end of the thermometer 7 with the bulb 2, which is convenient for experiments.
[0044] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0045] The cross scale 3 is a magnetic scale, and a magnetic strip or a metal strip attracted to the cross scale 3 is provided at the bottom of the test box 4. The use of a magnetic scale can improve the stability of the test box 4 after it is placed, so that the experimental effect is better.
[0046] like Figure 2 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0047] The temperature sensing module 5 is a temperature sensing probe, a sensing end of the temperature sensing module 5 is inserted into the test box 4 , and a limit block 51 is provided on the portion of the temperature sensing module 5 located outside the test box 4 .
[0048] Specifically, in this embodiment, the display module 6 is a display, and the display module 6 is electrically connected to the temperature sensing module 5 in a one-to-one correspondence.
[0049] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0050] There is a distance between the top of the operation port 11 and the inner top wall of the box 1, and the bulb 2 is located above the middle of the box 1. The part of the box 1 between the top of the operation port 11 and the inner top wall of the box 1 can form a lampshade design, which can block part of the light of the bulb 2 from the field of vision, and try to avoid the bulb 2 from shining directly on the students' eyes.
[0051] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:
[0052] A hinge plate 8 for closing the operation opening 11 is arranged on the side of the box body 1 , and the hinged portion between the hinge plate 8 and the box body 1 is located at the bottom of the operation opening 11 .
[0053] When the hinged plate 8 is closed, on the one hand, the light of the bulb 2 can be shielded, and on the other hand, the influence of air flow on the experimental data can be effectively prevented, thereby improving the experimental effect.
[0054] Furthermore, a timer 9 is provided on the box body 1; when the light bulb 2 is turned on, timing can be performed by the timer 9, which can better facilitate students' experiments.
[0055] Furthermore, to ensure the safety of students' use of electricity, this experimental box uses a 24V 100W bulb 2 and a 24V student power supply.
[0056] Furthermore, the box body 1 and the hinged plate 8 are made of waste wood boards, and the test box 4 is made of waste paper, which conforms to the concept of environmental protection and recycling.
[0057] In summary, this experimental box can be used to simultaneously explore the factors related to the amount of heat absorbed by the solar water heater, and the experiment of whether black objects can accelerate heat transfer; it can be used to explore the impact of a single factor on the experiment, and can also explore the impact of multiple factors on the experiment at the same time.
