Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of temperature detection, and particularly relates to a vortex tube cold and hot test equipment. BACKGROUND

[0002] Modern industrial products are faced with more and more complex use environments, and the temperature difference from the polar region to the equator can be more than 100 DEG C. When the chip temperature of an electronic product increases by 10 DEG C, the failure rate thereof increases exponentially. In a low-temperature environment, the capacitance of an electrolytic capacitor can be attenuated by more than 30 %, and the response speed is obviously decreased. Hidden dangers such as cracking of a circuit board welding point, falling of a component, and failure of a sealing element can be exposed under temperature impact. In particular, for a product assembled by using materials with different thermal expansion coefficients, the deformation difference caused by temperature change can cause structural damage. Behind these common product failures, there is a key link - temperature adaptability. All products must go through rigorous high and low temperature tests before going to the market, which is one of the most challenging links in the modern industrial product control system. The core of the high and low temperature test is to simulate the extreme environment. The "temperature impact" that can realize the drastic temperature difference change from low temperature to high temperature in a short time can find more problems that cannot be found by conventional detection than the simple continuous high temperature or low temperature.

[0003] The significance of the high and low temperature test mainly embodies in three aspects: firstly, improving product reliability, improving design by exposing weaknesses in advance; secondly, reducing after-sales risks, avoiding large-scale failures caused by environmental temperature changes; and thirdly, meeting industry standards, and many product certifications in the field are forced to pass the temperature impact test.

If a vortex tube cold and hot test equipment with simple structure, refrigeration and heating functions, maintenance-free, energy-saving and environment-friendly energy separation device can be designed, the above problems can be solved.

DETAILED DESCRIPTION

[0018] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a test module 1 and a vortex tube module 2. The vortex tube module 2 includes a box 3, a vortex tube 4, a solenoid valve 5, a triplet 6, and an air manifold 7. The triplet 6 is connected to the air inlet ends of several groups of the vortex tubes 4 through several groups of the solenoid valves 5. The cold air end and the hot air end of the vortex tube 4 are respectively matched with the air inlet cover module 8 on the test module 1 through the air manifold 7. It can be seen that when high and low temperature testing is required, the vortex tube module 2 is directly placed above the test module 1; the air outlet of the air manifold 7 is connected to the air inlet above the air inlet cover module 8 using an air pipe; and below each air inlet pipe joint. When high-temperature testing is required, the test equipment still follows the original test procedure to power and communicate with the mainboard. It only needs to control the solenoid valve of the vortex tube that supplies hot air. This way, the vortex tube can generate hot air and transport it through a pipeline to the top of the test machine platen. The product is tested at high temperature through the air outlet and air duct on the platen. At the same time, the temperature sensor provides real-time feedback on the intake air temperature. When the intake air temperature is higher than the test temperature, the temperature control program will control the opening and closing of the cold air vortex tube solenoid valve, inputting cold air to reduce the temperature of the hot air, thereby ensuring that the hot air temperature is within the required temperature range. The control principles of low-temperature testing and high-temperature testing are the same, and the control can be reversed.

[0019] like Figure 2 As shown, in this embodiment, two sets of vortex tubes 4 are respectively arranged in the middle of the box 3, the triplex 6 and the manifold 7 are respectively arranged on both sides of the box 3, and two sets of solenoid valves 5 are arranged at one end of the box 3. As can be seen, the symmetrical layout in the middle and on both sides of the box 3 can shorten the pipeline lines, better save space, and reduce the overall volume of the equipment.

[0020] like Figure 1 and Figure 4As shown in the embodiment, the air inlet cover plate module 8 includes an air inlet cover plate 81, cold air pipes 82 and hot air pipes 83. The cold air pipes 82 and the hot air pipes 83 are arranged on the upper end of the air inlet cover plate 81. The cold air pipes 82 and the hot air pipes 83 are respectively matched with the cold air outlet end and the hot air outlet end of the air collecting box 7. The cold air pipes 82 and the hot air pipes 83 are matched with the test assembly inside the test module 1. Thus, the cold air pipes 82 and the hot air pipes 83 respectively supply cold air and hot air.

[0021] As shown in the embodiment, Figure 4 As shown in the embodiment, the upper end of the air inlet cover plate 81 is provided with temperature sensors 84. The temperature sensors 84 are respectively matched with the cold air pipes 82 and the hot air pipes 83. Thus, the temperature sensors 84 can sense the temperature of the outlet air in real time and control the equipment to be adjusted synchronously.

[0022] As shown in the embodiment, Figure 2 As shown in the embodiment, the cold air end and the hot air end of the vortex tube 4 are respectively provided with sound reduction modules 9. Thus, the sound reduction modules 9 can reduce the noise generated during the air supply of the vortex tube 4.

[0023] As shown in the embodiment, Figure 3 As shown in the embodiment, the lower end of the box 3 is provided with sliding grooves 10. The box 3 is slidably matched with the slide rail module 11 at the upper end of the test module 1 through the sliding grooves 10. Thus, the vortex tube module 2 can be adjusted through the sliding grooves 10 and the slide rail module 11, which facilitates the pipe connection or maintenance operation.

[0024] As shown in the embodiment, Figure 3 As shown in the embodiment, the test module 1 is provided with a cylinder sliding module 12. The movable end of the cylinder sliding module 12 is connected with the lower end surface of the box 3. Thus, the cylinder sliding module 12 makes the equipment maintenance and pipe connection operation more automatic.

[0025] As shown in the embodiment, Figure 1 As shown in the embodiment, the upper end of the test module 1 is provided with a protective cover 13. The protective cover 13 is matched with the box 3. Thus, the protective cover 13 can provide an independent and safe detection environment for the equipment and prevent external factors from interfering with the detection.

[0026] As shown in the embodiment, Figure 1 As shown in the embodiment, the protective cover 13 is provided with handles 14 on both sides. Thus, the handles 14 facilitate the installation and disassembly of the protective cover 13.

[0027] As shown in the embodiment, Figure 1As shown, in the embodiment, the test module 1 is provided with a control module 15.

[0028] The working principle of the application: when high and low temperature test is needed, the vortex tube module 2 is directly placed above the test module 1; the gas outlet of the gas collecting tank 7 is connected to the gas inlet above the gas inlet cover plate module 8 by a gas pipe; and the temperature sensor is arranged below each gas inlet pipe joint. When high temperature test is needed, the test equipment is still powered and communicated according to the original test procedure; only the electromagnetic valve of the vortex tube for supplying hot air needs to be controlled to be opened, so that the vortex tube can generate hot air and deliver the hot air to the top of the test machine through the pipeline, and the hot air is tested through the gas outlet of the gas inlet cover plate module 8 and the air duct, while the temperature sensor feeds back the inlet temperature in real time; when the inlet temperature is higher than the required temperature, the temperature control program will control the on-off of the cold air vortex tube electromagnetic valve to input cold air to reduce the temperature of the hot air, so as to ensure that the temperature of the hot air is within the required temperature range. The control principle of low temperature test and high temperature test is the same, and the control is reversed.

[0029] Although the embodiments of the application are described in actual schemes, but do not constitute a limitation on the meaning of the application, for those skilled in the art, according to the modification of the embodiments and the combination with other schemes according to the present application are obvious.
