Description

Technical Field

[0001] This utility model relates to the field of pressure testing, specifically a variable frequency multi-station high-precision high and low temperature pressure testing device. Background Technology

[0002] New energy electronic medical devices refer to novel medical equipment that combines new energy technologies (such as solar, wind, and geothermal energy) with electronic medical devices. These devices utilize clean and sustainable energy to achieve stable power supply, thereby improving equipment operating efficiency and the sustainability of medical services. To facilitate high-precision testing of new energy medical devices, pressure testing equipment is required. The "High-Precision High and Low Temperature and High and Low Pressure Environmental Test Chamber" disclosed in application number "202123320872.0" represents an increasingly mature technology. This invention combines high-pressure, low-pressure, and high and low-temperature experimental functions through a temperature control system and a pressure control system, enabling a single device to perform the functions of multiple machines, saving cost and space. Simultaneously, temperature control of the test chamber is achieved by filling the inner chamber with liquid to control the temperature, eliminating the need for forced convection heat exchange with the inner chamber air, thus solving problems such as insufficient heat exchange and compressor liquid slugging under low-pressure testing conditions. Furthermore, the method of wrapping the inner chamber with liquid at the same temperature on all four sides for heat exchange improves the inner chamber temperature. The uniformity of temperature is significantly improved, especially under low-pressure conditions. Pressure and temperature are controlled by independent controllers, with the pressure controller employing an ultra-high precision level. All controls are then unified via communication through a single human-machine interface. This approach fulfills the current industry demand for a test chamber combining ultra-high precision pressure and temperature control. However, this test chamber has the following shortcomings: While the temperature control system, combined with a cooling solenoid valve, does perform temperature testing, the accuracy of high and low temperature detection is insufficient. Therefore, a pressure testing device with high precision high and low temperature testing and enhanced practicality is necessary. Furthermore, the heat dissipation and protection effects of this test chamber are inadequate. Therefore, a pressure testing device that significantly improves heat dissipation, protection, and extends service life is also necessary. Utility Model Content

[0003] The present invention provides a variable frequency multi-station high-precision high and low temperature pressure testing device, which aims to solve the problem that existing pressure testing devices are not convenient for simultaneously conducting high-precision high and low temperature tests on multiple experimental samples.

[0004] To achieve the above objectives, this utility model provides a variable frequency multi-station high-precision high and low temperature pressure testing device, including a pressure testing chamber;

[0005] The pressure testing chamber has several observation windows at its front end, several circulating air ducts inside, several tooling fixtures evenly spaced inside, several circulating pipes evenly spaced inside, and lead wire holes on the surface of each circulating pipe. Two control panels are mounted on the upper end of the pressure testing chamber, several door locks are mounted on the front end, heat dissipation holes are located at the lower end, a power distribution box is mounted on the back of the pressure testing chamber, and a power switch is mounted at the lower back of the pressure testing chamber.

[0006] As a preferred embodiment of this utility model, a housing is installed at the lower end of the pressure test chamber.

[0007] As a preferred embodiment of this utility model, the lower end of the pressure test chamber is detachably equipped with several foot cups and self-locking casters.

[0008] As a preferred embodiment of this utility model, the front end of the pressure test chamber is provided with a ventilation slot, and both sides of the pressure test chamber are provided with pressure relief holes.

[0009] As a preferred embodiment of this utility model, the upper end of the pressure test chamber is provided with several connecting grooves.

[0010] As a preferred embodiment of this utility model, a stable base is installed at the lower end of each of the aforementioned tooling fixtures.

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

[0012] 1. When conducting high-precision high and low temperature tests on new energy electronic medical devices using a pressure testing device, multiple test samples are simultaneously placed inside the pressure testing chamber by manual means and fixed to the upper end of the tooling fixture. External wires are led out through the test lead holes. After the door lock is engaged, the safety door is closed. At this time, the relevant test parameters are set through the control panel, and the equipment operates normally. The placed battery begins the test. After the test is completed, it is observed for 1 hour. At this time, the high-precision high and low temperature test operation can be carried out on multiple test samples simultaneously through several equidistant tooling fixtures, a circulating air duct, and an observation window. Compared with the test chamber in the existing technology "a high-precision high and low temperature high and low pressure environment test chamber", this utility model can carry out high-precision high and low temperature test operation on multiple test samples simultaneously through the above-mentioned structure, thereby improving the test efficiency and enhancing practicality.

[0013] 2. When using the pressure testing device, the circulating air duct and heat dissipation holes facilitate initial heat dissipation of the pressure testing chamber. Simultaneously, the pressure relief hole and ventilation slots further enhance ventilation and heat dissipation. Finally, the foot cups provide cushioning, ensuring the accuracy of sample testing. The self-locking casters facilitate the movement of the pressure testing device. Compared to the existing "high-precision high-low temperature and high-low pressure environment test chamber," this invention, through the combined structure of the above components, provides multiple heat dissipation and protection effects for the pressure testing device, thereby extending its service life.

In use, multiple test samples are manually placed into the chamber of the pressure test chamber 100 and secured using fixtures 103. External wires are led out through test lead holes 105, and the safety door is closed after locking with a door lock 107. Test parameters are then set via the control panel 106 to ensure normal operation. The placed battery then begins testing. After one hour of observation following the test, the use of several equidistant fixtures 103, along with the circulating air duct 102 and observation window 101, allows for simultaneous high-precision high and low temperature testing of multiple test samples. Therefore, this not only enhances the practicality of the pressure testing device but also improves testing accuracy and efficiency.

[0024] Please see Figures 2-4 A housing 111 is installed at the lower end of the pressure test chamber 100.

[0025] In one specific embodiment, the chassis 111 facilitates the containment and protection of various components, thereby improving the ease of use of the pressure testing device.

[0026] Please see Figures 2-4 The lower end of the pressure test chamber 100 is detachably equipped with several foot cups 121 and self-locking casters 122.

[0030] Please see Figures 2-4 The upper end of the pressure test chamber 100 is provided with several connecting grooves 141.

[0031] In one specific embodiment, the connecting groove 141 facilitates heat dissipation from the top of the pressure test chamber 100, thereby improving ventilation and heat dissipation.

[0033] In one specific embodiment, the stabilizing base 151 facilitates the stabilizing and limiting effect on the tooling fixture 103 from the lower end, thereby helping to ensure the accuracy of the test.

[0034] Working principle: In use, multiple test samples are first placed manually into the cavity of the pressure test chamber 100. Then, the test samples are fixed by the tooling fixture 103. External wires are led out through the test lead hole 105. At this time, the door lock 107 is engaged and the safety door is closed. The relevant test parameters are set through the control panel 106 to ensure the normal operation of the equipment. The placed battery begins the test. After the test is completed, it is observed for 1 hour. With several equidistant tooling fixtures 103, in conjunction with the circulating air duct 102 and the observation window 101, multiple test samples can be subjected to high-precision high and low temperature tests at the same time. This not only enhances the practicality of the pressure test device, but also improves the test accuracy and efficiency.
