Description

Technical Field

[0001] This utility model belongs to the technical field of DIC testing equipment, specifically relating to an environmental chamber. Background Technology

[0002] DIC testing technology is a digital image correlation technique. During the testing process, a high-speed camera is typically used to capture real-time images of the samples inside the environmental chamber through a glass door. The strain in the images is then extracted by software and matched with the stress to obtain a stress-strain curve. However, existing environmental chambers have inadequate structural designs and lack humidity control. During low-temperature testing, excessive humidity inside the chamber often causes fogging and frost formation on the glass door, thus affecting the high-speed camera's ability to capture images of the samples.

[0003] Therefore, it is essential to provide an environmental chamber capable of regulating humidity. Utility Model Content

[0004] Based on the shortcomings of existing technologies, the purpose of this utility model is to provide an environmental chamber that can regulate humidity.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An environmental chamber includes a chamber body with a door on one side. The door is fitted with transparent glass. The chamber body has a ventilation channel, an air inlet, and an air outlet, all of which are connected to the chamber body. The air inlet is connected to the exhaust end of an air compressor via a pipe, and the air outlet is connected to the intake end of the air compressor via a pipe. The ventilation channel of the chamber body is equipped with louvers. A temperature sensor and a humidity sensor are installed inside the chamber body. The air compressor is an air compressor chiller or an air compressor heater.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-3 This utility model provides an environmental chamber, including a chamber body 2, a door 1 on one side of the chamber body 2, and a transparent glass door 1. The environmental chamber has a ventilation channel 5, an air inlet 2, and an air outlet 4. The ventilation channel 5, the air inlet 2, and the air outlet 4 are respectively connected to the chamber body 1. The air inlet 3 is connected to the exhaust end of an air compressor through a pipe, and the air outlet 4 is connected to the intake end of an air compressor through a pipe. A louver 6 is provided in the ventilation channel 5 of the chamber body 2. A temperature sensor and a humidity sensor are provided inside the chamber body 2.

[0025] In one embodiment, the air compression device is an air compression refrigerator or an air compression heater.

[0026] In this utility model, the housing 2 is provided with a control panel 7 and a display screen 8, and the louvers 6 are electric louvers. The temperature sensor, humidity sensor, air compressor, louvers 6 and display screen 8 are electrically connected to the control panel 7 respectively.

[0027] The temperature sensor is used to detect the temperature inside the chamber 1, and the humidity sensor is used to detect the humidity inside the chamber 1. If the detected temperature deviates from the preset temperature or the detected humidity deviates from the preset humidity, the state of the compressed air equipment and the louvers 6 are controlled through the control panel 7 to adjust the temperature and humidity inside the chamber 1 to the range required by the DIC test. This is convenient to operate and avoids excessive humidity inside the environmental chamber from affecting the shooting effect.

[0028] In one embodiment, the air outlet 4 is located at the top of the housing 1, and the air inlet 3 and the ventilation channel 5 are located at the bottom of the housing 1.

[0029] The air outlet 4 is located at the top of the cabinet 1, and the air inlet 3 is located at the bottom of the cabinet 1. During refrigeration, it can effectively prevent the cold air output by the air compressor refrigeration unit from blowing directly onto the transparent glass of the cabinet door, thereby reducing the risk of the glass fogging.

[0030] In one embodiment, a ventilation device is also provided in the ventilation channel 5. The ventilation device and louvers are arranged sequentially along the ventilation direction of the ventilation channel. The ventilation device includes n honeycomb layers 10, where n is a positive integer not less than 1. The n honeycomb layers 10 are stacked sequentially along the ventilation direction of the ventilation channel 5. The honeycomb layer 10 has a number of evenly distributed holes 11, which penetrate the honeycomb layer 10 along the ventilation direction of the ventilation channel 5.

[0031] n is 3 to 5, and the holes 11 of two adjacent honeycomb layers 10 partially overlap in the ventilation direction of the ventilation channel 5.

[0032] For example, the overlap area of ​​the holes 11 of two adjacent honeycomb layers 10 in the ventilation direction of the ventilation channel 5 is 20 to 80% of the cross-sectional area of ​​the holes 11.

[0033] In this invention, the holes 11 of two adjacent honeycomb layers 10 partially overlap in the ventilation direction of the ventilation channel 5, which not only guides the incoming air but also slows down the airflow.

[0034] In this invention, the honeycomb layer 10 can be made of PP or aluminum.

[0035] In one embodiment, a moisture-proof cloth is provided inside the housing 2, located between the ventilation device and the louvers 6, and the moisture-proof cloth can cover the louvers 6.
