Description

Technical Field

[0001] This application relates to the field of artificial climate testing technology, and in particular to an internal circulation air outlet device for an artificial climate chamber. Background Technology

[0002] An artificial climate chamber is a device with functions such as lighting, humidification, and temperature control. It is used to provide an ideal artificial climate experimental environment and can be used for plant germination, seedling cultivation, tissue culture, microbial culture, insect and small animal breeding, BOD determination in water analysis, and other artificial climate experiments.

[0003] Currently, artificial climate chambers mainly consist of a main structural chamber (usually composed of two layers, with the outer layer being insulation material and the inner layer being stainless steel or other corrosion-resistant materials), a temperature control device (refrigeration and heating systems) for regulating the temperature inside the chamber, a humidification system for controlling the humidity inside the chamber, a lighting system, and an air supply system. Through the coordinated work of these components, various parameters such as temperature, humidity, and light intensity are adjusted to simulate the environment and create and maintain specific climatic conditions. However, improper installation of air outlets, improper installation of temperature control devices, uneven distribution of humidified mist inside the chamber forming a humidity gradient, or improper placement of experimental items obstructing the air ducts can all lead to uneven distribution of temperature and humidity inside the chamber, affecting the growth of crops grown inside. Utility Model Content

[0004] In order to make the temperature and humidity distribution inside the chamber uniform and to make the environmental simulation more realistic, this application provides an internal circulation air outlet device for an artificial climate chamber.

[0005] This application provides an internal circulation air outlet device for an artificial climate chamber, which adopts the following technical solution:

[0006] An internal circulation air outlet device for an artificial climate chamber, comprising:

[0007] An internal circulation air duct is installed inside the climate chamber and is arranged along the height of the climate chamber. The upper and lower sides of the internal circulation air duct are connected to the crop planting area inside the climate chamber.

[0008] A bracket is installed inside the internal circulation air duct. The bracket includes an air inlet plate and an air outlet plate. The air inlet plate has multiple air inlet holes, and the air outlet plate has multiple air outlet holes.

[0009] The fan is located at the air inlet, and multiple fans are set, each corresponding to one of the multiple air inlets.

[0010] By adopting the above technical solution, when the internal circulation air outlet device is activated, multiple fans start operating. The fans draw air from the crop planting area inside the climate chamber into the internal circulation duct. The air is guided within the internal circulation duct, flowing along the height of the climate chamber and transported to the top side of the climate chamber. When the air reaches the air outlet plate, it is released back into the crop planting area inside the climate chamber through multiple air outlets on the air outlet plate. During the air circulation process, moisture and temperature are evenly distributed, thereby ensuring a uniform temperature and humidity distribution on both the upper and lower sides of the climate chamber, avoiding local overheating or overcooling and humidity gradients. Through the combined action of the internal circulation duct, support frame, air inlet, air outlet, and fans, the air circulates between the internal circulation duct and the upper and lower sides of the climate chamber, ensuring a uniform distribution of temperature and humidity in the crop planting area inside the climate chamber. This improves the realism of the environmental simulation and the consistency of crop growth, providing a more controllable growth environment for experimental crops and improving the accuracy of experimental results.

[0011] Optionally, the internal circulation air outlet device further includes:

[0012] Two temperature sensors are provided, located on the upper and lower sides of the internal circulation air duct, respectively, to detect the temperature on the upper and lower sides of the crop planting area inside the climate chamber and to send out temperature detection signals.

[0013] Two humidity sensors are provided, located on the upper and lower sides of the internal circulation air duct, respectively, to detect the humidity on the upper and lower sides of the crop planting area inside the climate chamber and to send out humidity detection signals.

[0014] The controller, connected to the temperature sensor, humidity sensor, and fan, receives temperature and humidity detection signals to determine the temperature and humidity on the upper and lower sides of the crop planting area inside the climate chamber. When the temperature difference or humidity difference on the upper and lower sides of the crop planting area inside the climate chamber exceeds a preset value, the fan starts.

[0015] By adopting the above technical solution, two temperature sensors and two humidity sensors are located on the upper and lower sides of the internal circulation duct, respectively, to continuously monitor the temperature and humidity on the upper and lower sides of the crop planting area inside the climate chamber. The temperature and humidity detection signals are sent to the controller in real time. After receiving the signals from the temperature and humidity sensors, the controller analyzes the temperature and humidity data on the upper and lower sides. When the temperature or humidity difference between the upper and lower sides exceeds a preset value, the controller determines that the environmental conditions need adjustment. At this time, the fan starts, promoting air circulation between the internal circulation duct and the climate chamber, accelerating the uniform distribution of humidity and temperature. Through real-time monitoring by the temperature and humidity sensors, precise control of the environmental conditions inside the climate chamber can be achieved, ensuring uniform temperature and humidity distribution. Furthermore, it reduces the energy consumption of the fan, eliminating the need for prolonged fan operation and extending its service life.

[0016] Optionally, a guide plate is fixed at the air outlet of the air outlet plate. The guide plate is located on the side of the air outlet plate away from the air inlet plate, and the guide plate is inclined downward towards the side away from the air inlet plate.

[0017] By adopting the above technical solution, the downward tilt of the air guide plate can guide air into the crop planting area at a better angle, while also promoting uniform airflow, reducing airflow resistance, and enabling the blown air to achieve a better diffusion effect.

[0018] Optionally, wind deflectors are fixed on both sides of the air guide plate, and a wedge-shaped structure is formed between the air guide plate and the two wind deflectors.

[0019] By adopting the above technical solution, the baffle is used to limit the dispersion of air along both sides of the air guide plate. By forming a wedge-shaped structure, the air is made to flow more concentratedly along the downward direction of the air guide plate, thereby improving the efficiency of air flow, achieving more effective air dispersion and circulation, and further optimizing the distribution of temperature and humidity inside the climate chamber.

[0020] Optionally, the air outlets are arranged in multiple rows at uniform intervals along the height direction, and the multiple air outlets in each row are arranged at uniform intervals along the horizontal direction.

[0021] By adopting the above technical solution, the evenly and spaced air outlets make it less likely for airflows to interfere with each other, allowing air to cover the entire planting area more evenly.

[0022] Optionally, the bottom of the internal circulation duct is provided with multiple air inlets, which are elongated in shape.

[0023] By adopting the above technical solution, the elongated air intake hole can provide a larger air intake area and accelerate the internal air circulation efficiency. On the other hand, due to the special shape of the elongated hole, it can act as a physical barrier to reduce the entry of soil or other dust impurities into the internal circulation air duct, thereby making the internal circulation air outlet device less prone to blockage or pollution, which is conducive to the cleanliness and efficient operation of the internal circulation air duct.

[0024] Optionally, the air inlet plate and the air outlet plate are integrally formed.

[0025] By adopting the above technical solution, the air inlet and outlet plates are integrally molded, resulting in a firm connection, high strength, and stable use. This reduces airflow disturbance caused by shaking at the connection point, simplifies the assembly process, and lowers production costs.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the combined action of internal circulation air ducts, supports, air inlets, air outlets, and fans, air circulates between the internal circulation air ducts and the upper and lower sides of the climate chamber, ensuring a uniform distribution of temperature and humidity in the crop planting area inside the climate chamber. This improves the realism of the environmental simulation and the consistency of crop growth, providing a more controllable growth environment for experimental crops and improving the accuracy of experimental results.

[0028] 2. Two temperature sensors and two humidity sensors are located on the upper and lower sides of the internal circulation duct, respectively. They continuously monitor the temperature and humidity on the upper and lower sides of the crop planting area inside the climate chamber and send the temperature and humidity detection signals to the controller in real time. After receiving the signals from the temperature and humidity sensors, the controller analyzes the temperature and humidity data on the upper and lower sides. When the temperature or humidity difference between the upper and lower sides exceeds the preset difference, the controller determines that the environmental conditions need to be adjusted. At this time, the fan starts, which promotes the circulation of air between the internal circulation duct and the inside of the climate chamber, accelerating the uniform distribution of humidity and temperature. Through the real-time monitoring of the temperature and humidity sensors, precise control of the environmental conditions inside the climate chamber can be achieved, ensuring the uniform distribution of temperature and humidity, and reducing the energy consumption of the fan, so that the fan does not need to run for a long time and extends its service life.

[0029] 3. The downward tilt of the air guide plate guides air into the crop planting area at a better angle, while also promoting uniform airflow, reducing air resistance, and enabling better dispersion of the blown air. The baffle plate restricts air dispersion along both sides of the air guide plate. The wedge-shaped structure formed by the air guide plate and the baffle plate promotes more concentrated airflow along the downward tilt of the air guide plate, improving airflow efficiency, achieving more effective air dispersion and circulation, and further optimizing the distribution of temperature and humidity inside the climate chamber.

[0035] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0036] This application discloses an internal circulation air outlet device for an artificial climate chamber. (Refer to...) Figure 1 and Figure 2 The internal circulation air outlet device includes an internal circulation air duct 2 for installation inside the climate chamber 1. The internal circulation air duct 2 is installed along the height direction of the climate chamber 1, and the upper and lower sides of the internal circulation air duct 2 are connected to the crop planting area 3 inside the climate chamber 1.

[0037] Reference Figure 2 and Figure 3 The top of the internal circulation air duct 2 is detachably connected to a bracket 4 by bolts. The bracket 4 includes an air inlet plate 41 and an air outlet plate 42, which are integrally formed. The air inlet plate 41 has multiple air inlet holes 411, and the air outlet plate 42 has multiple air outlet holes 421. Multiple fans 5 are arranged below the air inlet holes 411, and the multiple fans 5 correspond one-to-one with the multiple air inlet holes 411.

[0038] Reference Figure 1 and Figure 2The bottom of the internal circulation duct 2 is provided with multiple air inlets 21. The air inlets 21 are elongated. The elongated shape of the air inlets 21 serves two purposes: firstly, it provides a larger air intake area, thereby accelerating the internal air circulation efficiency; secondly, due to the special shape of the elongated holes, it can act as a physical barrier, reducing the entry of soil or other dust impurities into the internal circulation duct 2. This makes the internal circulation outlet device less prone to blockage or contamination, which is conducive to the cleanliness and efficient operation of the internal circulation duct 2.

[0039] When the internal circulation air outlet device is activated, multiple fans 5 begin to operate. The fans 5 draw air from the crop planting area 3 inside the climate chamber 1 into the internal circulation duct 2. The air is guided within the internal circulation duct 2, flowing along the height of the climate chamber 1 and being transported to one side of the top. When the air reaches the air outlet plate 42, it is released back into the crop planting area 3 inside the climate chamber 1 through multiple air outlet holes 421 on the air outlet plate 42. During air circulation, moisture and temperature are evenly distributed, resulting in uniform temperature and humidity distribution on both the upper and lower sides of the climate chamber 1, preventing localized overheating or undercooling and humidity gradients. Through the combined action of the internal circulation duct 2, support 4, air inlet 411, air outlet 421, and fans 5, air circulates between the internal circulation duct 2 and the upper and lower sides of the climate chamber 1, promoting uniform temperature and humidity distribution in the crop planting area 3 inside the climate chamber 1, improving the realism of the environmental simulation and the consistency of crop growth.

[0040] Reference Figure 1 and Figure 2 The internal circulation air outlet device also includes two temperature sensors, two humidity sensors, and a controller. The two temperature sensors are located on the upper and lower sides of the internal circulation duct 2, respectively, to detect the temperature on the upper and lower sides of the crop planting area 3 inside the climate chamber 1 and send temperature detection signals. The two humidity sensors are also located on the upper and lower sides of the internal circulation duct 2, respectively, to detect the humidity on the upper and lower sides of the crop planting area 3 inside the climate chamber 1 and send humidity detection signals. The controller is connected to the temperature sensors, humidity sensors, and fan 5, and receives the temperature and humidity detection signals to determine the temperature and humidity on the upper and lower sides of the crop planting area 3 inside the climate chamber 1. When the temperature difference or humidity difference on the upper and lower sides of the crop planting area 3 inside the climate chamber 1 exceeds a preset difference, fan 5 starts.

[0041] Two temperature sensors and two humidity sensors are located on the upper and lower sides of the internal circulation duct 2, respectively, continuously monitoring the temperature and humidity on the upper and lower sides of the crop planting area 3 inside the climate chamber 1, and sending the temperature and humidity detection signals to the controller in real time. After receiving the signals from the temperature and humidity sensors, the controller analyzes the temperature and humidity data on the upper and lower sides. When the temperature or humidity difference detected on the upper and lower sides exceeds a preset value, the controller determines that the environmental conditions need to be adjusted. At this time, the fan 5 is started. The start of the fan 5 promotes the circulation of air between the internal circulation duct 2 and the climate chamber 1, accelerating the uniform distribution of humidity and temperature. Through the real-time monitoring of the temperature and humidity sensors, precise control of the environmental conditions inside the climate chamber 1 can be achieved, ensuring the uniform distribution of temperature and humidity, and reducing the operating energy consumption of the fan 5, so that the fan 5 does not need to run for a long time, thus extending its service life.

[0042] Reference Figures 2-4 Multiple rows of air outlets 421 are evenly spaced along the height direction, and multiple air outlets 421 in each row are evenly spaced along the horizontal direction. The even and spaced distribution of the air outlets 421 makes it difficult for airflow to interfere with each other, allowing the air to cover the entire planting area more evenly. A guide plate 6 is fixed at the air outlet 421 of the air outlet plate 42. The guide plate 6 is located on the side of the air outlet plate 42 away from the air inlet plate 41, and the guide plate 6 is inclined downward towards the side away from the air inlet plate 41. The downward inclination of the guide plate 6 can guide the air into the planting area 3 at a better angle, while also promoting the uniformity of airflow, reducing airflow resistance, and allowing the blown air to achieve a better diffusion effect. Wind deflectors 7 are fixed on both sides of the air guide plate 6, and a wedge structure is formed between the air guide plate 6 and the two wind deflectors 7. The wind deflectors 7 are used to restrict the air from spreading along both sides of the air guide plate 6. By forming a wedge structure, the air is made to flow more concentratedly along the downward direction of the air guide plate 6, thereby improving the efficiency of air flow, achieving more effective air diffusion and circulation, and further optimizing the distribution of temperature and humidity inside the climate chamber 1.

[0043] The implementation principle of the internal circulation air outlet device for an artificial climate chamber according to an embodiment of this application is as follows: When the internal circulation air outlet device is activated, multiple fans 5 start operating. The fans 5 draw air from the crop planting area 3 inside the climate chamber 1 into the internal circulation air duct 2. The air is guided within the internal circulation air duct 2, flows along the height direction of the climate chamber 1, and is transported to one side of the top of the chamber. When the air reaches the air outlet plate 42, it is released back into the crop planting area 3 inside the climate chamber 1 through multiple air outlet holes 421 on the air outlet plate 42. During the air circulation process, humidity and temperature are evenly distributed. The temperature and humidity are evenly distributed, thus ensuring uniform temperature and humidity distribution on both the upper and lower sides of the climate chamber 1, avoiding local overheating or undercooling and humidity gradients. Through the combined action of the internal circulation duct 2, support 4, air inlet 411, air outlet 421, and fan 5, the air circulates between the internal circulation duct 2 and the upper and lower sides of the climate chamber 1, resulting in a uniform distribution of temperature and humidity in the crop planting area 3 inside the climate chamber 1. This improves the realism of the environmental simulation and the consistency of crop growth, providing a more controllable growth environment for the experimental crops and improving the accuracy of the experimental results.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
