Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an automatic air thermal shock furnace. Background Technology

[0002] A thermal shock furnace is a specialized experimental device primarily used to test the thermal shock resistance and related physical and chemical properties of materials after experiencing rapid and extreme temperature changes. It simulates the thermal shock conditions that may be encountered in actual use to evaluate the degree of damage and performance stability of materials under drastic temperature changes.

[0003] In existing air-cooled thermal shock furnaces, when the sample needs to be cooled, the furnace's fan is turned on to blow air onto the sample surface, accelerating the airflow around the sample surface and enhancing the convection effect, allowing the air to carry away the sample surface temperature more quickly. However, since the fan only blows on one side of the sample, the airflow around the sample is uneven, resulting in a lower temperature on the side of the sample closer to the fan and a higher temperature on the side farther from the fan, affecting the test results and increasing data errors.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an automatic air thermal shock furnace. By setting up a cooling component 200, the advantage of this setting is to avoid uneven airflow speed around the sample, which would cause the temperature of the sample closer to the fan to be lower and the temperature of the sample farther away from the fan to be higher, thus preventing the test results from being affected and increasing the error of the data.

[0031] Specifically, the heating assembly 100 includes a device body 102, an air supply component 103 disposed on the device body 102, and an exhaust component 101 disposed on the device body 102, wherein a vent 102a is provided between the device body 102 and the air supply component 103, an exhaust port is provided at the top of the device body 102, and a fan is installed inside the air supply component 103; and the cooling assembly 200 includes a release component 202 disposed inside the device body 102 and a rotating component 201 disposed inside the device body 102, wherein the rotating component 201 and the release component 202 engage during cooling.

[0032] The device body 102 and the air conveyor 103 are connected by a ventilation hole 102a, which allows the air from the fan to be blown onto the air-borrowing plate 201d. The air from the fan can blow onto both the sample and the air-borrowing plate 201d. The rotating part 201 and the releasing part 202 mesh during cooling, which allows the horizontal air from the fan to blow the air-borrowing plate 201d and drive the first toothed disc 201c to rotate. After the second toothed disc 202c rotates, it drives the blades 202a to generate a vertically upward airflow.

[0033] In summary, by setting up the cooling component 200, when the worker starts the fan to blow the rotating part 201, the sample on the rotating part 201 rotates, so that every area of ​​the rotating part 201 can be blown by the fan. The advantage of this setting is that it avoids uneven airflow around the sample, which would cause the temperature of the sample closer to the fan to be lower and the temperature of the sample farther away from the fan to be higher, thus preventing the test results from being affected and increasing the error of the data.

[0034] Example 2

[0035] Reference Figures 1-5This is the second embodiment of the present invention. Unlike the previous embodiment, by setting a rotating component 201 and a releasing component 202, the advantage of this setting is to avoid uneven airflow speed around the sample, which would cause the temperature of the sample closer to the fan to be lower and the temperature of the sample farther from the fan to be higher, thus preventing the test results from being affected and increasing the error of the data.

[0036] Specifically, the exhaust component 101 includes a sliding rod 101a disposed on the main body 102 of the device, and a cover plate 101b adapted to the exhaust port is disposed on the top of the sliding rod 101a.

[0037] The main body 102 of the device includes a housing 102b, and a heating platform 102c is provided on the top inner wall of the housing 102b. The axis of the heating platform 102c is on the same straight line as the axis of the rotating member 201, and the axis of the release member 202 is on the same straight line as the axis of the cover plate 101b.

[0038] Both the housing 102b and the air supply component 103 are equipped with vents. Under normal conditions, the cover plate 101b blocks the exhaust port under the action of gravity.

[0039] The rotating component 201 includes a movable arm 201b that is slidably connected to the housing 102b. A first rotating rod 201a is provided at one end of the movable arm 201b away from the housing 102b, and a first toothed disc 201c is provided through the first rotating rod 201a.

[0040] The axis of the first gear 201c is on the same straight line as the axis of the first rotating rod 201a. A fixing block 201f is provided on the first rotating rod 201a. Several wind-boring plates 201d are evenly arranged around the axis of the first rotating rod 201a. A tray 201e is provided at the end of the first rotating rod 201a away from the moving arm 201b.

[0041] The top of the tray 201e is provided with several anti-slip grooves, and the distance between the two ends of the vent 102a is equal to the distance from the axis of the first toothed disc 201c to the inner wall of the housing 102b.

[0042] A second rotating rod 202b is provided on the bottom inner wall of the housing 102b. A second toothed disc 202c that meshes with the first toothed disc 201c is provided on the second rotating rod 202b. Several blades 202a are provided at the end of the second rotating rod 202b away from the bottom inner wall of the housing 102b.

[0043] Several blades 202a are evenly arranged around the axis of the second rotating rod 202b, and the blades 202a do not collide with the wind-borrowing plate 201d.

[0044] The axis of the heating platform 102c is on the same straight line as the axis of the rotating part 201, which facilitates the rotating part 201 to slide upward into the heating platform 102c and improves the heating efficiency. The axis of the release part 202 is on the same straight line as the axis of the cover plate 101b, which facilitates the discharge of hot air and improves the cooling efficiency of the thermal shock furnace.

[0045] Vents are provided on both the shell 102b and the air conveyor 103. The vent on the shell 102b facilitates the handling of samples by workers, while the vent on the air conveyor 103 facilitates the drawing of external air by the fan when the thermal shock furnace is cooling. Under normal conditions, the cover plate 101b blocks the exhaust port under the action of gravity, which not only prevents dust from falling into the thermal shock furnace from the exhaust port and causing poor wiring of electrical equipment, but also prevents the loss of heat inside the thermal shock furnace.

[0046] The top of the tray 201e is provided with several anti-slip grooves to increase static friction when the sample rotates and prevent the sample from moving. The distance between the two ends of the vent 102a is equal to the distance from the axis of the first toothed disc 201c to the inner wall of the housing 102b, so that the horizontal wind from the fan can blow onto the wind-borrowing plate 201d and make the rotation arc of the wind-borrowing plate 201d semi-circular.

[0047] The blade 202a does not come into contact with the wind-inducing plate 201d, thus avoiding mutual interference between the blade 202a and the wind-inducing plate 201d when they rotate.

[0048] In summary, by setting the rotating component 201 and the releasing component 202, the worker opens the vent of the housing 102b, places the sample on the tray 201e, and then closes the vent of the housing 102b. At this time, the first toothed disc 201c and the second toothed disc 202c are in a meshing state. Then, the heating component 100 is activated to control the moving arm 201b to slide upward, driving the first rotating rod 201a, the first toothed disc 201c, the wind-boring plate 201d, the fixing block 201f, and the tray 201e to slide upward until the sample on the tray 201e moves into the heating stage 102c for heating. After heating, the moving arm 201b slides down again, driving the sample to reset and the first toothed disc 201c and the second toothed disc 202c to be in a meshing state again.

[0049] At the same time, the vent of the air supply component 103 is opened and the fan is started. The horizontal air blown by the fan blows through the vent 102a onto the air-borrowing plate 201d and the sample. The air-borrowing plate 201d is pushed and rotated by the wind, which drives the first toothed disc 201c, the first rotating rod 201a, the fixed block 201f and the tray 201e to rotate, thereby driving the sample to rotate, so that the surface of the sample is evenly blown. The advantage of this setting is to avoid uneven airflow speed around the sample, which would cause the temperature of the sample closer to the fan to be lower and the temperature of the sample farther away from the fan to be higher, thus preventing the test results from being affected and increasing the error of the data.

[0050] Example 3

[0051] Reference Figures 1-5 This is the third embodiment of the present invention. Unlike the previous embodiment, an exhaust component 101 is provided. The advantage of this arrangement is that hot air is prevented from accumulating inside the thermal shock furnace, thereby improving the cooling efficiency of the thermal shock furnace.

[0052] Specifically, the wind force after the blade 202a rotates is greater than the weight of the cover plate 101b.

[0053] The horizontal air blown by the fan turns the cold air into hot air after passing over the high-temperature sample. However, in order to prevent the hot air from blowing directly out of the side wall of the housing 102b and causing burns, an exhaust hole is opened at the top of the housing 102b so that the hot air can be discharged from the top of the housing 102b.

[0054] The wind force after the blade 202a rotates is greater than the weight of the cover plate 101b, which makes it easier for the vertical upward wind blown by the blade 202a to push the cover plate 101b and make the sliding rod 101a slide upward, exposing the exhaust hole to discharge hot air.

[0055] In summary, by setting up the exhaust component 101, when the first gear disk 201c rotates, it drives 202c to rotate, which in turn drives the second rotating rod 202b and blade 202a to rotate. The blade 202a generates wind power. Since the cold air blown towards the sample and the high temperature of the sample surface achieve heat exchange, the air blown over the sample becomes hot air and continues to blow until it blows onto the inner wall of the end of the shell 102b away from the fan. Since the weight of hot air is less than that of cold air, the hot air moves upward into the exhaust port. At this time, the vertical upward air blown out by the blade 202a not only accelerates the upward movement of the hot air, but also pushes open the cover plate 101b and causes the sliding rod 101a to slide upward, exposing the exhaust port. The hot air is then discharged from the exhaust port. The advantage of this setting is that it avoids the accumulation of hot air in the thermal shock furnace and improves the cooling efficiency of the thermal shock furnace.
