Description

Technical Field

[0001] This utility model relates to a multifunctional ice-water test chamber, which is mainly suitable for testing the performance of core components such as automobile engines, aircraft engines, new energy motors and transmission mechanisms, thermal management modules, and chips under complex working conditions. Background Technology

[0002] With the continuous development of science and technology and modern industry, countries around the world are vigorously developing green transportation tools such as new energy vehicles. The performance and safety and reliability indicators of some important components, such as power battery systems, power motor systems, heat pipe control systems, and control chips, which are core components of new energy vehicles, directly determine the development direction and future of new energy transportation tools.

[0003] To ensure that products can achieve their maximum performance and reliability while maintaining safety and energy efficiency, extensive testing is required to simulate their worst operating conditions and the most demanding and extreme testing conditions. The entire testing process involves the development, design, manufacturing, and inspection processes.

[0004] Due to product upgrades and continuous technological advancements, ice water testing standards are constantly evolving, from basic alternating tests of ice water spraying and high-temperature environments to alternating tests of ice water immersion and high-temperature environments. More complex conditions exist, including combinations of ice water spraying, ice water immersion, high-temperature impact, and post-test freezing and thawing. Traditional single-function ice water testing equipment can no longer meet these complex requirements. Multiple sets of equipment are needed to barely complete the tests, and test pieces must be manually transferred between different devices, significantly increasing the workload and safety risks for staff. Furthermore, different standards require different equipment, necessitating the purchase of additional single-function equipment, consuming significant space, and increasing energy consumption and installed power. Summary of the Invention

[0005] This utility model provides a multi-functional ice water test chamber that meets various testing standards and experimental requirements, is compact and small in size, saves space, is energy-saving and environmentally friendly, is easy to operate, and improves work efficiency.

[0006] The purpose of this utility model is achieved as follows:

[0007] A multifunctional ice-water test chamber includes a main body comprising an upper chamber and a lower water tank. A suspended basket is installed between the chamber and the water tank, and the basket moves up and down via a lifting mechanism at the top of the main body. A sample basket is placed in the basket. A refrigeration evaporator, a heater, and an impeller are located at the rear of the chamber. The impeller is connected to a motor outside the main body, and the refrigeration evaporator is connected to an external refrigeration system. An ice-water evaporator is located inside the water tank and is connected to the external refrigeration system. A circulation pump is located outside the water tank and is connected to the water tank via a water pipe. An opening is located on the side of the chamber, with a small door at the opening. The small door moves up and down as controlled by the lifting mechanism. A nozzle is located directly opposite the opening, and an ice-water pump delivers ice water from the water tank to the nozzle and sprays it out.

[0008] The suspended platform is equipped with an upper sealing strip and a lower sealing strip at the top and bottom, respectively.

[0009] A flow meter is installed between the water pump and the nozzle.

[0016] See Figure 1 and Figure 2This utility model relates to a multifunctional ice water test chamber, including a test chamber body 1. The test chamber body 1 includes an upper working chamber 13 and a lower water tank 3. A suspended basket 9 is installed between the working chamber 13 and the water tank 3. The suspended basket 9 can move up and down via a lifting mechanism 11 at the top of the test chamber body 1, thus allowing the suspended basket 9 to switch back and forth between the working chamber 13 and the water tank 3. The upper and lower parts of the suspended basket 9 are respectively provided with an upper sealing strip 8 and a lower sealing strip 14, which allow the working chamber 13 and the water tank 3 to be sealed separately without affecting each other. A sample basket 10 is placed in the suspended basket 9 for mounting test specimens, and a cable hole 12 is provided at the top of the suspended basket 9 to meet the requirements of power supply and communication for the test specimens.

[0017] The rear of the chamber 13 is equipped with a refrigeration evaporator 4, a heater 5, and an impeller 6. The impeller 6 is connected to a motor 7 outside the main body 1 of the test chamber, and the refrigeration evaporator 4 is connected to an external refrigeration system, forming a complete circulating refrigeration and heating system. The coordinated operation can control the temperature inside the chamber 13, which can be freely set according to the test requirements.

[0018] The water tank 3 is equipped with an ice water evaporator 2, which is connected to an external refrigeration system to control the ice water 15 in the water tank 3 at the test standard temperature of 0-4 degrees Celsius. A circulation pump 16 is provided outside the water tank 3, which is connected to the water tank 3 through a water pipe to allow the ice water 15 to circulate fully, thereby increasing the heat exchange efficiency and the uniformity of the ice water 15 temperature.

[0019] The working chamber 13 has an opening 22 on its side, with a small door 20 at the opening 22. The small door 20 is controlled by a lifting mechanism 21 to move up and down, thereby opening and closing the small door 20. A specially designed nozzle 19 is located directly opposite the opening 22. A water pump 17 delivers chilled water 15 from the water tank 3 to the nozzle 19 and sprays it out. A flow meter 18 is installed between the water pump 17 and the nozzle 19 to control the flow rate of the chilled water and for flow monitoring.

[0020] The common ice water spray test of this multifunctional ice water test chamber is implemented as follows: the basket remains stationary in the upper working chamber, the test specimen is placed in the sample basket, the temperature in the working chamber is controlled at the required high temperature, and the ice water in the lower water tank is controlled at a temperature of 0-4 degrees Celsius. When water spraying is required, the lifting mechanism drives the small door upward, opening the small door to expose the opening, the water pump runs, and delivers the pre-temperature ice water through the nozzle to spray it onto the test specimen. After spraying, the small door closes downward, and this process is repeated until the test is completed.

[0021] The ice water immersion test is conducted as follows: the basket remains stationary in the upper working chamber, the test specimen is placed in the sample basket, the temperature in the working chamber is controlled at the required high temperature, and the ice water in the lower water tank is controlled at a temperature of 0-4 degrees Celsius. When the immersion test begins, the lifting mechanism pushes the basket downward to immerse the test specimen in the ice water for a specified time. Then the basket is raised again to place the test specimen in the high-temperature environment of the working chamber. This process is repeated a certain number of times as required until the test is completed.

[0022] For other tests, the test pieces are immersed in ice water at 0-4 degrees Celsius, then returned to the working chamber where the temperature is controlled to be below 0 degrees Celsius. This causes the remaining ice water on the test pieces to freeze. After a certain period of time, the test pieces are then immersed in the water tank again until the test is completed.

[0023] The above are the three most typical test requirements. Because temperature and action can be set according to the test requirements, more different test requirements and measurement objectives can be achieved through different logic programs.
