Technical Field

[0001] This application relates to the field of laminar flow cleanroom cabinets, and more particularly to a sealing and heat insulation structure for a laminar flow cleanroom cabinet. Background Technology

[0002] A laminar flow cleanroom is a device that provides a locally highly clean environment through laminar flow technology, and is widely used in laboratories, medical facilities, and pharmaceutical companies. Its core principle is to use high-efficiency particulate air (HEPA) filters to create a uniform unidirectional airflow (vertical or horizontal), using a "piston flow" effect to directionally remove contaminants, thereby maintaining the cleanliness of the work area. In order to kill microorganisms in the gas or ensure the stability of gas delivery, existing laminar flow clean cabinets are usually equipped with heating devices and FFU fans. However, the existing FFU fans and cabinets are not well sealed, which makes it easy for internal heat to be lost. Therefore, a sealed and heat-insulating structure for laminar flow clean cabinets is needed. Utility Model Content

The air outlet of the FFU fan 13 is located on the left side of the electric heating tube 15. The air inlet of the FFU fan 13 is located away from the electric heating tube 15. The FFU fan 13 is fitted to the inside of the cabinet 1 by an external sealing ring.

[0030] Among them, the dimensions of FFU fan 13 are sealed and fitted to the internal dimensions of cabinet 1, and FFU fan 13 is horizontally arranged; When in use, by sealing and insulating the FFU fan 13, the heat loss of the internal air can be reduced, thereby improving the overall heating efficiency.

[0031] Reference Figure 1 Diagram and Figure 6 The sealing installation assembly includes a sealing frame 18 set inside the cabinet 1. A bottom shell 17 is fixedly installed inside the sealing frame 18. The sealing frame 18 and the heat insulation plate 19 are connected as a whole. The sealing frame 18 and the heat insulation plate 19 are separated and sealed from the cabinet 1, and a sealed cavity is formed inside, which encloses the FFU fan 13. An opening 5 is opened on one side of the cabinet 1, and a sliding door 6 is sealed and hinged inside the opening 5.

The sealing frame 18 and the heat insulation plate 19 form a sealed cavity, and the FFU fan 13 is sealed and heat-insulated, which can reduce the heat loss of the internal air and improve the overall heating efficiency. By installing the two integrated blocks 22 on the FFU fan 13 into the corresponding mounting slots 21, the cover on the protective box 20 can be opened, and the suction cup 30 can be moved, thereby releasing the suction installation with the knob 29, and further positioning the knob 29. At this time, the knob 29 can be rotated. Rotating the knob 29 will drive the rotating column 28 to rotate, which will drive the rotating plate 23 to rotate as well, and drive the two corresponding first connecting plates 24 to rotate. The two second connecting plates 25 will rotate and push the two protruding plates 26 away from each other. The two protruding plates 26 will move away from each other and can be inserted into the corresponding grooves 27, thereby completing the fixed installation of the integrated block 22, and thus completing the fixed installation of the FFU fan 13.
