Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically to an integrated circulating fan assembly structure for a test chamber. Background Technology

[0002] A test chamber is a professional device used to simulate various environmental conditions for performance testing, reliability verification, or scientific research of products, materials, and components. When using a test chamber, an integrated circulating fan assembly structure is required to circulate the air inside the chamber.

[0003] Existing circulating fan assembly structures include a motor, a heat insulation layer, a connecting frame, and an impeller. The motor is fixedly connected to the impeller through the heat insulation layer via a motor shaft at the output end. This causes the heat insulation cotton and heat insulation plate inside the heat insulation layer to fit closely with the motor shaft. When the motor shaft rotates at high speed, the heat insulation cotton, heat insulation plate, and motor shaft generate high-speed friction, resulting in a large amount of heat being generated at the connection point. After long-term use, the heat accumulation affects the normal operation of the motor shaft. Therefore, it is necessary to propose a circulating fan assembly structure with auxiliary cooling to cool down the high temperature at the connection point between the heat insulation cotton, heat insulation plate, and motor shaft.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-6 As shown, this utility model is an integrated circulating fan assembly structure for a test chamber, comprising:

[0029] The circulating flow assembly includes a heat insulation layer 11, a motor 12, and a connecting shaft 16. The motors 12 are arranged in a group and are all fixed to one side of the heat insulation layer 11. The connecting shaft 16 is fixed to the output end of the motors 12 and one end of the connecting shaft 16 passes through the heat insulation layer 11.

[0030] The circulating component also includes a fixed frame 13, a connecting frame 14 and an impeller 15; the fixed frame 13 is fixed to the other two ends and the center of the insulation layer 11; the connecting frame 14 is set up as a group and is fixed to the two outer ends of the fixed frame 13 respectively; the impeller 15 is located between the inner sides of the connecting frame 14; and one end of the connecting shaft 16 is fixedly connected to the impeller 15.

[0031] The heat insulation layer 11 is used to connect the motor 12 and the fixed frame 13. The motor 12 is used to connect the connecting shaft 16. Two motors 12 form a group and are controlled to rotate in both directions. After the impeller 15 is assembled, it can provide a more stable and efficient air circulation. The fixed frame 13 is used to connect the connecting frame 14. The connecting frame 14 is used to place the impeller 15. The connecting shaft 16 is used to connect the impeller 15 and the motor 12. The motor 12 and the heat insulation layer 11 are designed with load-bearing fixed sheet metal. The joint is equipped with a deformable heat-resistant sealing ring.

[0032] The cooling assembly includes a perforation 21, an air intake ring 22, a cooling groove 23, and a connecting pipe 24. The perforation 21 is opened at the through-hole between the connecting shaft 16 and the heat insulation layer 11. The air intake ring 22 is fixed inside the perforation 21 and is engaged with the surface of the connecting shaft 16. The cooling groove 23 is opened inside the air intake ring 22. The connecting pipes 24 are arranged in a group and are fixed at equal intervals on one side of the air intake ring 22.

[0033] The perforation 21 is used to connect the intake ring 22, the intake ring 22 is used to open the cooling tank 23, the cooling tank 23 is used to place the cooling gas, and the connecting pipe 24 is used for the external cooling gas to enter the cooling tank 23.

[0034] A connection hole 25 is provided on one side of the intake ring 22, and the connection hole 25 is fixedly connected to one end of the connecting pipe 24;

[0035] A circular hole 26 is provided at the center of the outer end of the connecting pipe 24, and a flexible hose 27 is fixedly connected to the outer side of the circular hole 26.

[0036] Cooling tank 23, connecting hole 25 are connected to the inside of connecting pipe 24, and hose 27 is connected to the inside of connecting pipe 24 through circular hole 26;

[0037] The connecting hole 25 is used for the connection between the connecting pipe 24 and the interior of the cooling tank 23, and the circular hole 26 is used for the connection between the hose 27 and the interior of the connecting pipe 24, so that the cooling gas enters the connecting pipe 24 through the hose 27 and the circular hole 26, and enters the cooling tank 23 through the connecting pipe 24 and the connecting hole 25, thereby allowing the intake ring 22 to cool the connecting shaft 16 through the cooling gas.

[0038] Working principle: When the component is not in use, the cooling gas does not enter the hose 27. When the component is in use, the cooling gas enters the connecting pipe 24 through the hose 27 and the circular hole 26, and then enters the cooling tank 23 through the connecting pipe 24 and the connecting hole 25. When the motor 12 drives the connecting shaft 16 to rotate at high speed, the air intake ring 22 separates the heat insulation layer 11 from the connecting shaft 16. At the same time, the cooling gas in the cooling tank 23 cools the connecting shaft 16, thereby reducing the high temperature of the connecting shaft 16 through the connecting pipe 24, the air intake ring 22, and the cooling gas in the cooling tank 23.

[0039] Please see Figures 1-4 , Figure 6 As shown, this embodiment, based on the above embodiment, further includes:

[0040] Limiting components;

[0041] The limiting component includes a plug groove 31, a plug rod 32, and a connecting cylinder 33; the plug groove 31 is set in a group and is equally spaced at one edge outside the through hole 21; one end of the plug rod 32 is threaded to the inside of the plug groove 31, and the connecting cylinder 33 is threaded to the outside end of the plug rod 32.

[0042] A snap-fit ​​ring 34 is fixedly connected to the outer end of the connecting tube 33, and the snap-fit ​​ring 34 is snapped into the hose 27;

[0043] The insertion slot 31 is used for inserting the insertion rod 32, the insertion rod 32 is used for connecting the connecting cylinder 33, the connecting cylinder 33 is used for connecting the locking ring 34 and the insertion rod 32, the locking ring 34 is used to limit the hose 27, the locking ring 34 is made of PVC board and has toughness, pushing the hose 27 causes the hose 27 to squeeze the locking ring 34 by the thrust, causing the outer end of the locking ring 34 to move to both sides, causing the locking ring 34 to lock with the hose 27, so that the locking ring 34 limits the hose 27 and prevents the hose 27 from getting tangled on the surface of the high-speed rotating connecting shaft 16.

[0044] Working principle: When the component is not in use, the plug rod 32 is not inserted into the plug slot 31. When the component is in use, insert one end of the plug rod 32 into the plug slot 31 by hand and rotate the plug rod 32 so that the plug rod 32 is connected to the plug slot 31 through the thread. Hold the retaining ring 34 by hand and insert the connecting cylinder 33 into the outer end of the plug rod 32. Rotate the retaining ring 34 so that the connecting cylinder 33 is connected to the outer end of the plug rod 32 through the thread. At this time, squeeze the retaining ring 34 and the hose 27 by hand. Since the retaining ring 34 is made of PVC board, the pushing force causes the outer end of the retaining ring 34 to move to both sides, so that the retaining ring 34 and the hose 27 are locked together, so that the retaining ring 34 limits the hose 27 and prevents the hose 27 from getting tangled on the surface of the high-speed rotating connecting shaft 16.
