Description

Technical Field

[0001] This utility model relates to the field of electric heater manufacturing, and in particular to an electric heater tube testing device for testing electric heaters. Background Technology

[0002] As a common tubular electrical component, the electric heating tube's main function is to efficiently convert electrical energy into heat energy. Its internal structure includes a heating wire, a resistance wire, and insulating powder. With its advantages such as affordability and ease of use, the electric heating tube has been widely used in various heating scenarios.

[0003] In the heating test of small and medium-sized electric heating tubes, most current testing devices use refractory bricks to construct the test chamber. Although this method is low-cost and economical, it has significant shortcomings in heat preservation during high-temperature testing. Due to poor heat preservation, heat is easily lost, making it difficult to maintain a stable high-temperature test environment. This situation directly leads to errors during the test, affecting the accuracy and reliability of the test results. It cannot provide accurate basis for the performance evaluation of electric heating tubes and has an adverse impact on the research and development and quality control of related products. Utility Model Content

[0004] In order to overcome the shortcomings of poor thermal insulation performance of the test chamber in the existing technology, the technical problem of this utility model is to provide a test device for testing electric heating tubes with good thermal insulation performance of the test chamber.

[0005] The technical implementation scheme of this utility model is as follows: an electric heating tube testing device for testing electric heaters, including a controller, a ribbon cable interface is installed at the rear of the test chamber, a controller for setting the test temperature is connected to the ribbon cable interface, the controller and the test chamber are electrically connected through the ribbon cable interface, a temperature sensor for detecting its internal temperature is installed at the top of the test chamber, the temperature sensor is electrically connected to the controller, a sliding groove is provided at the bottom of the test chamber, a placement pull-out plate is slidably connected to the test chamber through the sliding groove, an installation port for installing the electric heating tube to be tested is fixedly connected to the placement pull-out plate, and the test chamber is wrapped with heat insulation cotton to enhance its heat preservation performance.

[0006] Optionally, the test chamber also includes a baffle. A cooling fan is installed on the right side of the test chamber to reduce the internal temperature of the test chamber when needed. A baffle is also slidably connected to the right side of the test chamber. The baffle is located outside the fan and its size is slightly larger than the total area of ​​the fan. It is used to isolate the fan from the flow of outside air when heat dissipation is not required. A limiting plate is fixedly connected to the right side of the test chamber to limit the vertical sliding of the baffle.

[0007] Optionally, the system also includes a filter screen, which is fixedly connected to the air inlet of the fan to filter dust entering the test chamber.

[0008] Optionally, it also includes a magnet, with a magnet for attracting the baffle mounted on the bottom of the limiting plate.

[0009] Optionally, it also includes an observation window, which is fixedly connected to the pull-out plate for observing the test conditions inside the chamber.

[0010] Optionally, it also includes a handle, which is fixedly connected to the pull-out plate to facilitate its pulling.

[0011] Compared with the prior art, this utility model has the following advantages: the heat insulation cotton around the test chamber and the tight sealing structure work together to increase the heat preservation performance during the test process, ensure that the test environment can maintain a stable high temperature state, and guarantee the accuracy of the test results.

[0012] By opening the baffle, the cooling fan starts and draws in outside air to remove heat from the test chamber, thus achieving a cooling function and improving testing efficiency and safety.

[0013] The baffle can be attracted by magnets to prevent it from shaking during heat dissipation. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] Example: A heating element testing device for testing electric heaters, such as... Figure 1-3As shown, the device includes a controller 1, a ribbon cable interface 2, a test chamber 3, a temperature sensor 4, a pull-out plate 5, a mounting port 6, and thermal insulation cotton 7. The ribbon cable interface 2 is mounted on the rear of the test chamber 3, and the controller 1, used to set the test temperature, is connected to the ribbon cable interface 2. The controller 1 and the test chamber 3 are electrically connected via the ribbon cable interface 2. The temperature sensor 4, used to detect the internal temperature, is mounted on the top of the test chamber 3 and is electrically connected to the controller 1. A sliding groove is provided at the bottom of the test chamber 3, and the pull-out plate 5 is slidably connected to the test chamber 3 through the groove. The mounting port 6, used to install the heating element to be tested, is fixedly connected to the pull-out plate 5. The test chamber 3 is wrapped with thermal insulation cotton 7 to enhance its heat insulation performance. It also includes a baffle 8, a limiting plate 9, and a fan 10. The cooling fan 10 is mounted on the right side of the test chamber 3 for heat dissipation when needed. To lower the internal temperature of the test chamber 3, a baffle 8 is slidably connected to the right side of the test chamber 3. The baffle 8 is made of iron-chromium-aluminum alloy and is located outside the fan 10. Its size is slightly larger than the total area of ​​the fan 10. It is used to isolate the fan 10 from the flow of outside air when heat dissipation is not required. A limiting plate 9 is fixedly connected to the right side of the test chamber 3 to limit the vertical sliding of the baffle 8. A filter screen 11 is also included. The filter screen 11 is fixedly connected to the air inlet of the fan 10 to filter dust entering the test chamber 3. A magnet 12 is also included. The bottom of the limiting plate 9 is equipped with a magnet 12 for attracting the baffle 8. An observation window 13 is also included. The observation window 13 for observing the test conditions inside the chamber is fixedly connected to the pull-out plate 5. A handle 14 is also included. The pull-out plate 5 is fixedly connected to the handle 14 to facilitate its pulling.

[0020] First, use the handle 14 to slide the placement pull-out plate 5 out of the test chamber 3 via the slide groove, and install the heating element to be tested on the mounting port 6 of the placement pull-out plate 5, ensuring a secure installation. The user can adjust the number of heating elements to be tested according to actual needs. Slide the placement pull-out plate 5 into the test chamber 3 via the slide groove, close the test chamber 3, and set the required temperature for this test on the controller 1. At this time, the controller 1 will control the test chamber 3 to start working according to the set temperature. The temperature sensor 4 will detect the temperature inside the test chamber 3 in real time and feed the data back to the controller 1. If the temperature does not reach the set value, the test chamber 3 will continue to heat; if the set value is reached, it will remain stable. At this time, the user can... The observation window 13 allows observation of the testing conditions inside the test chamber 3. Simultaneously, the heat insulation cotton 7 surrounding the test chamber 3 and the tightly sealed structure work together to increase heat preservation performance during the testing process, ensuring a stable high-temperature test environment and guaranteeing the accuracy of the test results. If the temperature inside the test chamber 3 becomes too high and requires heat dissipation during or after the test, the baffle 8 is opened, and the magnet 12 attracts the baffle 8 to prevent it from shaking. The cooling fan 10 is activated, drawing in outside air to remove heat from the test chamber 3, thus achieving cooling. The filter 11 at the air inlet of the fan 10 filters in incoming dust, ensuring the cleanliness of the inside of the test chamber 3. When heat dissipation is not required, the baffle 8 is closed, simultaneously isolating the fan 10 from the flow of outside air.
