Description

Technical Field

[0001] This utility model relates to the field of windless testing technology, and in particular to a structure for achieving ultra-low wind speed inside a test chamber. Background Technology

[0002] In the research and testing process of modern electronics, drones, energy storage and other industries, many electronic components or equipment are in a windless or extremely low wind speed environment in actual operation. However, in order to ensure the cooling rate and the uniformity of temperature difference, our test equipment often has a certain wind speed in the test chamber when the equipment is working.

[0003] Currently, existing test chambers typically employ forced air circulation systems to ensure cooling rate and temperature uniformity. This results in high wind speeds within the test chamber, generally averaging 1-3 m / s, and temperature uniformity typically only reaching ≤2℃. This windy environment does not match the actual operating conditions of the equipment, which may lead to deviations in test results and affect the accuracy and reliability of product performance evaluation.

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] Please see Figure 1 ,in, Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0017] This utility model discloses a structure for achieving ultra-low wind speed inside a test chamber, comprising a wind box body 101, a temperature and humidity sensor 102, an air exchange pipe 103, a return air perforation plate 104, an airflow temperature regulating component 105, an air supply mechanism 106, an air supply pipe 107, an air filter 108, and an air distribution structure 109. The air exchange pipe 103 has a dehumidifier inlet 110, a dehumidifier outlet 111, a steam humidification port 112, and an overflow port 113. The airflow temperature regulating component 105 includes an evaporator 1... The air supply mechanism 106 includes a blower motor 116 and a centrifugal fan blade 117, and the air distribution structure 109 includes a top air duct 118, a wind speed control curtain 119, and a pressure equalization plate 120. The wind speed control curtain 119 has multiple uniform speed adjustment holes. Through the aforementioned scheme, an air duct structure with ultra-low wind speed (≤0.2m / s) and high temperature uniformity (≤0.5℃) is achieved based on the requirements of a more realistic test environment, thereby increasing the accuracy and reliability of product performance evaluation.

[0018] The temperature and humidity sensor 102 is disposed inside the air box body 101; the air exchange pipe 103 is connected to the air box body 101 and located on one side of the air box body 101; the return air perforated plate 104 is fixedly connected to the air exchange pipe 103 and located on one side of the air exchange pipe 103; the airflow temperature regulating component 105 is disposed on one side of the air exchange pipe 103; the air supply mechanism 106 is disposed on one side of the air exchange pipe 103; the air supply pipe 107 is connected to both the air exchange pipe 103 and the air box body 101 and is located between the air exchange pipe 103 and the air box body 101; the air filter 108 is fixedly connected to the air supply pipe 107 and located inside the air supply pipe 107; the air distribution structure 109 is disposed inside the air box body 101 and controls the air supply mechanism 106 to perform airflow delivery during the delivery process. The airflow temperature regulator 105 adjusts the temperature of the airflow, ensuring that the temperature inside the airbox body 101 is higher or lower than the ambient room temperature. The temperature-regulated airflow is then delivered to the air distribution structure 109 via the air supply duct 107. The temperature and humidity sensor 102 detects the temperature and humidity of the delivered airflow to facilitate temperature adjustment. The airflow is then uniformly and slowly delivered to the airbox body 101 via the air distribution structure 109, creating an ultra-low wind speed (≤0.2m / s) and high temperature uniformity (≤0.5℃) airflow duct structure within the airbox body 101. The airflow then returns to the air interaction duct 103 via the return air perforation plate 104, achieving airflow circulation. This meets the requirements of a more realistic testing environment, achieving an ultra-low wind speed (≤0.2m / s) and high temperature uniformity (≤0.5℃) airflow duct structure, increasing the accuracy and reliability of product performance evaluation.

[0019] Secondly, the dehumidifier air inlet 110 is located on one side of the air exchange pipe 103; the dehumidifier air outlet 111 is located on one side of the air exchange pipe 103; the steam humidification port 112 is located on one side of the air exchange pipe 103; and the overflow port 113 is located on one side of the air exchange pipe 103. The dehumidifier air inlet 110 and the dehumidifier air outlet 111 are used to connect to the dehumidifier and then dehumidify the returning airflow to maintain the dryness of the airflow. The steam humidification port 112 is used to humidify the airflow with the humidification equipment to increase the humidity of the delivered airflow. The overflow port 113 is used to drain the accumulated water in the air exchange pipe 103.

[0020] Furthermore, the evaporator 114 is fixedly connected to the air exchange pipe 103 and located inside the air exchange pipe 103; the heater 115 is fixedly connected to the air exchange pipe 103 and located inside the air exchange pipe 103. The evaporator 114 is used to cool the airflow, which works in conjunction with the low-temperature system to provide cooling to the work chamber, so that the temperature of the work chamber can be lower than the ambient temperature of the room. The heater 115 is used to heat the airflow, which provides heat to the work chamber, so that the temperature of the work chamber can be higher than the ambient temperature of the room.

[0021] In addition, the blower motor 116 is fixedly connected to the air exchange pipe 103 and is located on one side of the air exchange pipe 103; the centrifugal fan blade 117 is fixedly connected to the output end of the blower motor 116 and is located on one side of the blower motor 116. Starting the blower motor 116 drives the centrifugal fan blade 117 to rotate to achieve low-speed airflow delivery.

[0022] Furthermore, the top air duct 118 is fixedly connected to the air box body 101 and communicates with the air supply pipe 107, and is located on one side of the air box body 101; the wind speed control curtain 119 is fixedly connected to the top air duct 118 and is located on one side of the top air duct 118; multiple uniform speed adjustment holes are respectively located on one side of the wind speed control curtain 119; the pressure equalization plate 120 is fixedly connected to the top air duct 118 and is located on one side of the top air duct 118. The top air duct 118 is used to receive the airflow after temperature and humidity treatment transmitted by the air supply pipe 107, and then the wind speed control curtain 119, in conjunction with multiple uniform speed adjustment holes 121, is used to reduce the air outlet wind speed and to evenly distribute the airflow. The pressure equalization plate 120 makes the airflow more uniform in all places.

[0023] In using this invention, the blower motor 116 drives the centrifugal fan 117 to rotate, achieving low-speed airflow transport. During transport, the airflow temperature regulator 105 adjusts the temperature of the airflow. The evaporator 114 is used to cool the airflow, working in conjunction with the low-temperature system to provide cooling to the work chamber, ensuring the temperature of the work chamber is lower than the ambient room temperature. The heater 115 is used to heat the airflow, providing heat to the work chamber, ensuring the temperature of the work chamber is higher than the ambient room temperature. The temperature inside the air box body 101 is then either higher or lower than the ambient room temperature. The temperature-regulated airflow is then transported through the air supply pipe 107 to the top air duct 118. The temperature and humidity sensor 102 detects the temperature and humidity of the incoming airflow. The top air duct 118 is used to receive the airflow after temperature and humidity treatment transmitted by the air supply pipe 107, and then the airflow is reduced at the outlet by the wind speed control curtain 119 in conjunction with multiple uniform speed adjustment holes 121, so as to achieve uniform airflow. The pressure equalization plate 120 makes the airflow more uniform at all points, so that an air duct structure with ultra-low wind speed (≤0.2m / s) and high temperature uniformity (≤0.5℃) is formed in the air box body 101. Then, the airflow returns to the air interaction pipe 103 through the return air perforation plate 104 to achieve airflow circulation. Based on the requirements of a more realistic test environment, an air duct structure with ultra-low wind speed (≤0.2m / s) and high temperature uniformity (≤0.5℃) is achieved, which increases the accuracy and reliability of product performance evaluation.
