[0002] With the development of social economy and science and technology, all walks of life have higher and higher requirements for R&D and production environment. Clean rooms have been widely used in semiconductor, biomedicine, experimental animal facility laboratories. Clean rooms need to control technical indicators such as temperature, humidity, cleanliness, pressure difference, illumination, vibration, noise, etc., and need to use ice water units, water pumps, fans, cooling towers, dehumidifiers, electric heating, electric humidification and other equipment. Clean rooms usually run continuously for 24 hours, and the energy consumption is very large.

[0003] The air conditioning and ventilation system of the experimental animal facility should control the temperature and humidity as required. When the ambient humidity is higher than the index requirement, the air conditioning system generally cools and dehumidifies the fresh air, and then increases the supply air temperature through electric heating to meet the standard requirements. Since this cooling and dehumidification method has the problem of cold and heat offsetting each other, it causes additional energy loss, resulting in higher system energy consumption.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] As shown in 1-4, a dehumidification device for experimental animals with a three-dimensional heat pipe includes a box body 1, a working chamber is provided inside the box body 1, an air inlet is provided at one end of the box body 1, and an air outlet is provided at the other end of the box body 1, a U-shaped three-dimensional heat pipe 5 and a surface cooler 4 are provided inside the working chamber, and the surface cooler 4 is located inside the U-shaped three-dimensional heat pipe 5. A fan 7 matched with the air outlet is provided inside the working chamber, and filter components matched with the air inlet and the air outlet are respectively provided inside the box body 1;

[0030] The filter assembly includes a filter screen 10 and a first fixed frame 8 and a second fixed frame 9 respectively fixed inside the box body 1. A fixed plate 14 is fixed on the bottom surface of the box body 1. The fixed plate 14 is located between the first fixed frame 8 and the second fixed frame 9. Both sides of the fixed plate 14 are provided with clamping members for fixing the filter screen 10 on the inner sides of the first fixed frame 8 and the second fixed frame 9 respectively. The inner diameter of the mesh of the filter screen 10 decreases from the air inlet to the air outlet. The multiple filter screens 10 filter the inhaled air. First, the inhaled air is initially filtered, and then passes through the U-shaped three-dimensional After the heat pipe 5 pre-cools, the surface cooler 4 cools and dehumidifies, and the U-shaped three-dimensional heat pipe 5 reheats, that is, the air passes through the pre-cooling section of the U-shaped three-dimensional heat pipe 5, which has a preliminary cooling effect, and then passes through the surface cooler 4 for supercooling and dehumidification. The supercooled air passes through the reheating section of the U-shaped three-dimensional heat pipe 5, and the temperature rises to the corresponding supply air temperature. During the dehumidification process, the U-shaped three-dimensional heat pipe 5 uses the internal medium evaporation heat absorption / condensation heat dissipation principle to complete the heat exchange at both ends of the surface cooler 4, thereby reducing the reheating cost. When the fan 7 is working, the incoming air is efficiently filtered through the filter 10 again and then discharged for supply air.

[0031] Furthermore, the clamping member includes a pressure block 11 and a limit block 15 which are respectively slidably arranged at both ends of one side of the fixed plate 14. One side of the fixed plate 14 is respectively provided with a sliding cavity for sliding the pressure block 11 and the limit block 15. The pressure block 11 is connected to the sliding cavity through a first spring 16, and the limit block 15 is connected to the sliding cavity through a second spring 17. The stiffness coefficient of the first spring 16 is greater than the stiffness coefficient of the second spring 17. One end of the pressure block 11 movably passes through the outside of the sliding cavity and is inclined near the side of the limit block 15. A pull rope 12 is fixedly arranged at the other end of the pressure block 11. The other end of the pull rope 12 movably passes through the sliding cavity and is fixedly connected to the limit block 15. Under the reset action of the first spring 16, the second spring 17 is reset. 17 is in a compressed state, that is, the limit block 15 is in the sliding cavity, and then the filter screen 10 is pushed and installed between the fixing plate 14 and the first fixing frame 8 or the second fixing frame 9. One end of the filter screen 10 first abuts against the inclined surface of the pressure receiving block 11 and squeezes it to make the pressure receiving block 11 move into the sliding cavity, so that the first spring 16 is compressed. When the other end of the filter screen 10 is located inside the limit block 15, the limit block 15 is reset by the second spring 17 and quickly pops out of the sliding cavity and is stuck on the outside of the filter screen 10, thereby fixing the filter screen 10. The installation operation is relatively convenient. When the filter screen 10 is disassembled later, the staff only needs to squeeze the limit block 15 into the sliding cavity.

[0032] Furthermore, a condensate pan 18 cooperating with the surface cooler 4 is provided on the inner bottom surface of the box body 1, a drain pipe 6 cooperating with the condensate pan 18 is penetrated through the side wall of the box body 1, and a fan rack for installing the fan 7 is provided inside the box body 1.

[0033] Furthermore, one side of the box body 1 is provided with an inspection port that cooperates with the filter assembly and is cooperated with a first sealing door 2, and one side of the box body 1 is provided with a repair and inspection port that cooperates with the working chamber and is cooperated with a second sealing door 3, which is convenient for staff to repair and replace internal parts of the box body 1.

[0034] Furthermore, an installation cavity is opened in the middle of the fixing plate 14, and guide rollers 13 for guiding the pull rope 12 are rotatably arranged in the installation cavity. The pull rope 12 is a non-elastic rope, and the guide rollers 13 guide the pull rope 12 to effectively avoid contact wear during the movement of the pull rope 12.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
