Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this invention is to provide a novel temperature control device for salt spray testing, which solves the problems existing in the prior art, effectively improves the temperature control response speed, effectively improves the accuracy of temperature control, and effectively enhances the efficiency and accuracy of salt spray testing.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a novel temperature control device for salt spray testing, such as... Figure 1As shown, it includes: a housing, a partition, a temperature and humidity control mechanism, and multiple radiant heating plates. The partition is disposed inside the housing to divide the housing into a salt spray test area and an equipment area. The temperature and humidity control mechanism includes an air circulation mechanism, a heater, and a humidifier. The air circulation mechanism is disposed in the equipment area, and both its air inlet and outlet are connected to the salt spray test area to facilitate air exchange between the salt spray test area and the equipment area. The heater is disposed in the equipment area to heat the air entering the equipment area, and the humidifier is disposed in the equipment area to humidify the air entering the equipment area. Each of the radiant heating plates... A radiant heating plate is installed in the salt spray test area to maintain the temperature of the salt spray test area. The chamber is divided into a salt spray test area and an equipment area, which can prevent salt spray from corroding the equipment in the equipment area and improve the service life of the equipment. Before the test, the air circulation mechanism, heater and humidifier realize the air circulation and exchange between the two areas, thereby quickly adjusting the temperature and humidity of the salt spray test area to the experimental requirements, shortening the time to achieve the test temperature and humidity, and improving the accuracy of test temperature control. During the test, the air circulation mechanism is turned off and the temperature of the salt spray test area is controlled by the radiant heating plate, which improves the efficiency of temperature control and reduces the impact on the airflow in the test area.

[0025] In a preferred embodiment, the air circulation mechanism includes a circulating fan, an air supply section, and a return air section. The return air section is located at one end of the partition plate, and the air supply section is located at the other end of the partition plate. Both the return air section and the air supply section are used to connect the salt spray test area and the equipment area. The circulating fan is located at the air supply section, enabling the air to form a stable and effective circulation path between the salt spray test area and the equipment area. The location of the circulating fan at the air supply section ensures that the air entering the salt spray test area has sufficient flow rate and pressure, ensuring that the temperature and humidity regulation effect uniformly covers the test area, and improving the efficiency and consistency of temperature control.

[0026] In a preferred embodiment, the air supply section is an air supply outlet, and the air return section is an air return outlet.

[0027] In a preferred embodiment, the air circulation mechanism further includes a first air valve and a second air valve. The first air valve is located in the return air section, and the second air valve is located in the supply air section. The configuration of the first and second air valves allows for flexible adjustment of the return and supply air volumes. Based on different test environments and requirements, the air circulation volume can be optimized, thereby more accurately regulating the temperature and humidity of the salt spray test area to the experimental requirements. Furthermore, during the experiment, the first and second air valves respectively close the return air section and the supply air section, ensuring that the air velocity in the salt spray test area is 0 m / s. This effectively eliminates interference factors caused by airflow, and the variables in the experiment are strictly controlled, ensuring that the corrosive effect of salt spray on the product is only affected by key factors such as temperature, humidity, and the characteristics of the salt spray itself. This makes the test process simpler, the test results more stable and reliable, and facilitates accurate analysis and evaluation of the product's corrosion resistance.

[0028] In a preferred embodiment, both the first and second air valves are electric air valves. Electric air valves facilitate automated control and can cooperate with intelligent control systems to adjust the valve opening in a timely and accurate manner based on data feedback from temperature and humidity sensors, thereby improving the timeliness and accuracy of control, reducing manual intervention, and enhancing the level of intelligence in salt spray test temperature control.

[0029] In a preferred embodiment, the novel salt spray test temperature control device further includes a temperature and humidity sensor. The temperature and humidity sensor is located within the salt spray test area and near the return air section. The temperature and humidity sensor, installed near the return air section, can promptly and accurately acquire the temperature and humidity of the air flowing out of the salt spray test area, providing real-time data support for the intelligent control system. This allows for timely adjustment of the operating status of equipment such as heaters and humidifiers, effectively ensuring that the temperature and humidity within the salt spray test area are always maintained within the precise range required for the test.

[0030] In a preferred embodiment, the novel salt spray test temperature control device further includes a surface cooler, which is disposed in the equipment area. The surface cooler, the heater, the humidifier, and the circulating fan are arranged sequentially from the return air section to the supply air section. The surface cooler, heater, humidifier, and other equipment are arranged in this order, which can sequentially cool, heat, and humidify the air during air circulation, so that the temperature and humidity of the air entering the salt spray test area can more accurately and stably meet the test requirements, effectively improving the precision of temperature and humidity control.

[0031] In a preferred embodiment, the novel salt spray test temperature control device further includes multiple temperature sensors, which are positioned close to the corresponding radiant heating plates. Positioning the temperature sensors close to each radiant heating plate enables real-time and accurate monitoring of the temperature near each radiant heating plate, facilitating the intelligent control system to individually and precisely adjust the heating state of each radiant heating plate. This ensures a more uniform temperature distribution within the salt spray test area and meets the stringent temperature uniformity requirements of different tests.

[0032] In a preferred embodiment, the partition plate, the first air valve, and the second air valve are all made of salt spray corrosion resistant material. Using salt spray corrosion resistant material to make these components can ensure that the partition plate, air valve, and other components will not be damaged by salt spray corrosion under long-term salt spray test environment, thereby maintaining the structural integrity and performance stability of the device, reducing the frequency of device maintenance and component replacement, and reducing the cost of use.

[0033] In a preferred embodiment, the novel salt spray test temperature control device further includes an intelligent control system. The intelligent control system is electrically connected to the heater, the humidifier, the circulating fan, the first air valve, the second air valve, the temperature and humidity sensor, and the temperature sensor. The intelligent control system enables centralized and precise control of each device, and automatically adjusts the device operating parameters based on the data fed back from the sensors. This greatly improves the accuracy and automation of temperature control, eliminates the need for frequent manual intervention, effectively improves the efficiency of the salt spray test, and ensures the stability and repeatability of the test conditions.

[0034] In a preferred embodiment, the radiant heating plate is made of graphene composite heating material, and its surface is made of salt spray corrosion resistant material. The graphene composite heating material has good heating performance and efficiency, and can quickly and uniformly increase the temperature of the salt spray test area. The surface is made of salt spray corrosion resistant material to prevent the radiant heating plate from being corroded in the salt spray environment, extend its service life, and at the same time ensure that the heating performance is not affected by salt spray erosion, and maintain a stable and reliable temperature control effect.

[0035] The method of using this new salt spray test temperature control device is as follows:

[0036] Experimental preparation phase

[0037] Equipment Startup and Initialization: The intelligent control system is activated, starting all equipment, including the circulating fan, heater, humidifier, and surface cooler, bringing the equipment into initial standby mode. The intelligent control system performs self-checks on each device to confirm that all components are fault-free and communication is normal. For example, it checks the electrical connections between the device and the heater, humidifier, circulating fan, first air valve, second air valve, temperature and humidity sensor, and temperature sensor to ensure they are secure.

[0038] Set test parameters: Based on the specific requirements of the salt spray test, set parameters such as target temperature and humidity values, test duration, etc., in the intelligent control system. For example, set the temperature of the salt spray test area to 35℃ and the humidity to 95% RH.

[0039] Air circulation and temperature / humidity pre-regulation: The intelligent control system opens the first and second air valves to appropriate degrees, activating the circulating fan to exchange air between the salt spray test area and the equipment area. Air enters the equipment area from the return air section, first passing through a surface cooler to cool it according to the current air temperature and humidity and test requirements; then it is heated by a heater and humidified by a humidifier. The temperature and humidity regulated air then returns to the salt spray test area from the supply air section. During this process, temperature and humidity sensors collect real-time air temperature and humidity data in the salt spray test area near the return air section and feed it back to the intelligent control system. Based on the feedback data, the intelligent control system adjusts the operating power and status of the heater, humidifier, and other equipment to quickly regulate the temperature and humidity of the salt spray test area to near the experimental requirements.

[0040] Experimental phase

[0041] Enclosed test area and maintaining stable airflow: When the temperature and humidity of the salt spray test area are close to the set values, if the air velocity in the salt spray test area needs to be 0m / s according to the test requirements, the intelligent control system will control the first and second air valves to close, ensuring that the air in the salt spray test area is in a relatively static state, reducing the interference of airflow on the test, and making the corrosive effect of salt spray on the product only affected by key factors such as temperature, humidity and the characteristics of the salt spray itself.

[0042] Precise Temperature Control: During the test, multiple temperature sensors positioned near the corresponding radiant heating plates monitor the temperature near each plate in real time and feed the data back to the intelligent control system. Based on the temperature distribution within the salt spray test area and preset temperature values, the intelligent control system automatically and precisely adjusts the heating power of each radiant heating plate individually to maintain a uniform and stable temperature within the set value within the salt spray test area. For example, if the temperature in a certain area is slightly lower, the intelligent control system automatically increases the heating power of the radiant heating plates near that area.

[0043] End of test phase

[0044] Equipment shutdown and cleanup: After the test, shut down the heater, humidifier, circulating fan and other equipment.

[0045] Data recording and analysis: The real-time data recorded by the temperature and humidity sensors and temperature sensors during the test are exported from the intelligent control system. The test data are organized and analyzed, the changes in the corrosion resistance of the product before and after the test are compared, and the test results and related conclusions are summarized to provide an important basis for subsequent product research and development and improvement.

[0046] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
