Description

Technical Field

[0001] This utility model relates to the field of high temperature test chamber technology, specifically a precision high temperature test chamber with uniform temperature distribution. Background Technology

[0002] To test product quality, various environmental tests, such as high-temperature tests, are usually required. Currently, commonly used equipment for high-temperature environmental testing includes high-temperature test chambers, high-temperature alternating test chambers, high-temperature damp heat test chambers, and high-temperature alternating damp heat test chambers. These are primarily used to provide the necessary simulated test environment for verifying the heat resistance and dryness resistance of various materials. They are suitable for testing products in fields such as electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, medical, and aerospace.

[0003] When conducting high-temperature tests on samples, a high-temperature test chamber is required. However, the high-temperature test chamber does not have a circulation function, which leads to stagnant gas inside the chamber. This results in uneven heating of the chamber by the heating plate, thus affecting the sample testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precision high-temperature test chamber with uniform temperature distribution, which has the advantages of uniform heating inside the test chamber and solves the problem of uneven heating inside the test chamber.

[0005] This utility model relates to a precision high-temperature test chamber with uniform temperature distribution, comprising a chamber body. Heating plates are provided on both sides of the top of the chamber's inner cavity. A circulation guide assembly, including a fan, is located at the top of the chamber body. Both input ends of the fan are connected to suction pipes, one end of which penetrates and extends into the inner cavity of the chamber body. One end of the suction pipe has a suction hole. The output end of the fan is connected to an outlet pipe, the bottom of which penetrates and extends into the inner cavity of the chamber body. The bottom of the outlet pipe is connected to an outlet hood, and the bottom of the outlet hood has an outlet hole. When heating is required inside the chamber, this utility model first... First, the chamber is heated by a heating plate. At this time, the fan runs, drawing air from inside the chamber into the suction pipe through the suction hole. The air is then transported to the fan, then to the exhaust pipe, and finally to the exhaust hood. The exhaust hood then blows the air back into the chamber through the exhaust holes. This allows the air to circulate within the chamber, resulting in a more even distribution of heat. This leads to better performance of the samples during testing and avoids the problem of stagnant airflow in high-temperature test chambers, which can cause uneven heating by the heating plate and negatively impact the test results.

[0006] This utility model relates to a precision high-temperature test chamber with uniform temperature distribution. The surface of the suction pipe is fixedly fitted with a limiting plate, and one side of the limiting plate is fixedly connected to the inner wall of the chamber. The limiting plate can fix the suction pipe, thus improving the suction pipe's performance during use and preventing it from shaking and causing unstable airflow.

[0007] This utility model relates to a precision high-temperature test chamber with uniform temperature distribution. The exposed surface of the suction pipe is covered with a heat insulation cover made of heat insulation cotton. The heat insulation cover can keep the exposed suction pipe warm when hot air inside the chamber is drawn into the fan through the suction pipe, thus preventing heat from dissipating through the exposed suction pipe and increasing the energy consumption of the heating plate.

[0008] This utility model relates to a precision high-temperature test chamber with uniform temperature distribution. The bottom of the chamber's inner cavity is fixedly connected to a worktable. Both sides of the bottom of the chamber are equipped with electric push rods. The output end of the electric push rod passes through and extends into the inner cavity of the chamber. The output end of the electric push rod is equipped with a clamping plate. When the sample container is placed on the worktable, the electric push rod operates, driving the clamping plate to move inward. The clamping plate can fix the container and prevent it from tipping over when placed on the worktable.

[0009] This utility model relates to a precision high-temperature test chamber with uniform temperature distribution. The surface of the electric push rod is fixedly fitted with a fixing plate, and the inner cavity of the fixing plate is fixedly connected to the chamber body by fixing bolts. The fixing plate and fixing bolts can fix the electric push rod, so that the electric push rod performs better when in use and avoids the electric push rod shaking during use, which would lead to the unstable movement of the clamping plate driven by the electric push rod.

[0010] The present invention relates to a precision high-temperature test chamber with uniform temperature distribution, wherein the bottom of the chamber is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with anti-slip particles.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When heating is required inside the chamber, this utility model first heats the chamber through a heating plate. At this time, the fan runs, drawing air from inside the chamber into the suction pipe through the suction hole. The air is then transported to the fan, then to the exhaust pipe, and finally to the exhaust hood. The exhaust hood then blows the air back into the chamber through the exhaust holes. This allows the air to circulate within the chamber, resulting in a more even distribution of heat. This leads to better performance of the samples during testing and avoids the problem of stagnant gas flow in high-temperature test chambers, which can cause uneven heating by the heating plate and affect the sample testing.

[0013] 2. This utility model uses a limiting plate to fix the suction pipe, which makes the suction pipe more effective during use and avoids shaking during use, thus preventing unstable suction.

[0014] The insulation cover can keep the exposed air intake pipe warm when the hot air inside the box is drawn into the fan through the air intake pipe, thus preventing heat from dissipating through the exposed air intake pipe and thus increasing the energy consumption of the heating plate.

[0015] When the sample container is placed on the worktable, the electric push rod operates, which drives the clamping plate to move inward. The clamping plate can fix the container and prevent it from tipping over when placed on the worktable.

[0016] The electric actuator can be fixed in place by using a fixing plate and fixing bolts. This makes the electric actuator work better and avoids shaking during use, which could lead to instability in the movement of the clamping plate driven by the electric actuator.

[0023] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0024] Please see Figure 1-4 This utility model discloses a precision high-temperature test chamber with uniform temperature distribution, comprising a chamber body 1. Heating plates 9 are provided on both sides of the top of the inner cavity of the chamber body 1. A circulation guide assembly 8 is provided within the inner cavity of the chamber body 1, including a fan 801 located at the top of the chamber body 1. Both input ends of the fan 801 are connected to suction pipes 804, one end of which penetrates and extends into the inner cavity of the chamber body 1. A suction hole 805 is provided at one end of the surface of the suction pipe 804. The output end of the fan 801 is connected to an outlet pipe 807, the bottom of which penetrates and extends into the inner cavity of the chamber body 1. An outlet hood 806 is connected to the bottom of the outlet pipe 807, and an outlet hole 808 is provided at the bottom of the outlet hood 806. When heating is required inside the chamber body 1, this utility model first uses heating plates 9 to heat the chamber body. The hot plate 9 heats the interior of the chamber 1. At this time, the fan 801 operates, drawing air from the chamber 1 into the suction pipe 804 through the suction hole 805. The air is then transferred to the fan 801 through the suction pipe 804, and finally to the exhaust pipe 807 through the fan 801. The air is then transferred to the exhaust hood 806 through the exhaust hole 808 in the exhaust hood 806, and finally blown back into the chamber 1 through the exhaust hole 808. This allows the air to circulate within the chamber 1, resulting in a more even distribution of hot air. Consequently, the samples in the chamber 1 perform better during testing. This avoids the problem of the high-temperature test chamber lacking circulation and airflow, which would otherwise cause the gas inside the high-temperature test chamber to stagnate, resulting in uneven heating by the heating plate 9 and affecting the sample testing.

[0025] A limiting plate 803 is fixedly sleeved on the surface of the suction pipe 804, and one side of the limiting plate 803 is fixedly connected to the inner wall of the housing 1. The limiting plate 803 can fix the suction pipe 804, so that the suction pipe 804 has a better effect when used and avoids the suction pipe 804 from shaking during use, which would lead to unstable suction.

[0026] The exposed surface of the suction pipe 804 is covered with a heat insulation cover 802, and the heat insulation cover 802 is made of heat insulation cotton. Through the heat insulation cover 802, when the hot air in the box 1 is drawn into the fan 801 through the suction pipe 804, the exposed suction pipe 804 can be insulated, thus preventing heat from dissipating through the exposed suction pipe 804 and thus increasing the energy consumption of the heating plate 9.

[0027] A workbench 6 is fixedly connected to the bottom of the inner cavity of the box 1. Electric push rods 4 are provided on the bottom of both sides of the box 1. The output end of the electric push rod 4 passes through and extends into the inner cavity of the box 1. A clamping plate 7 is provided at the output end of the electric push rod 4. When the sample container is placed on the workbench 6, the electric push rod 4 runs, and the clamping plate 7 moves inward through the electric push rod 4. The clamping plate 7 can fix the container and prevent the container from tipping over when placed on the workbench 6.

[0028] The surface of the electric push rod 4 is fixedly fitted with a fixing plate 2, and the inner cavity of the fixing plate 2 is fixedly connected to the housing 1 by fixing bolts 3. The fixing plate 2 and fixing bolts 3 can fix the electric push rod 4, so that the electric push rod 4 performs better when in use and avoids the electric push rod 4 shaking during use, which would lead to the electric push rod 4 driving the clamping plate 7 to move unstably.

[0029] The bottom of the box 1 is provided with an anti-slip pad 5, and the bottom of the anti-slip pad 5 is provided with anti-slip particles.

[0030] When using this utility model: When heating is required inside the chamber 1, the heating plate 9 first heats the inside of the chamber 1. At this time, the fan 801 runs, drawing air from inside the chamber 1 into the suction pipe 804 through the suction hole 805. The air is then transferred to the fan 801 through the suction pipe 804, and then to the exhaust pipe 807 through the fan 801. The air is then transferred to the exhaust hood 806 through the exhaust pipe 807, and finally blown back into the chamber 1 through the exhaust hole 808 in the exhaust hood 806. This allows the air to flow inside the chamber 1, thus making the hot air more evenly distributed inside the chamber 1. As a result, the samples inside the chamber 1 perform better during testing. This avoids the situation where the high-temperature test chamber lacks circulation and guidance functions, which would lead to stagnant gas inside the high-temperature test chamber, causing uneven heating by the heating plate 9 and affecting the sample testing.

Various modifications and variations can be made to this utility model by those skilled in the art.
