Abstract
Description
Technical Field
[0001] This invention relates to a refrigeration system, and more particularly to a refrigeration system applied to processing equipment. Background Technology
[0002] During the laser processing equipment manufacturing process, a large amount of heat is generated, affecting the normal operation of the equipment. To reduce the internal heat, a cooling system is usually installed to ensure the normal operation of the equipment. Currently used cooling systems include cooling equipment, whose output cold air is connected to the ventilation openings of the processing equipment via flexible hoses. The ventilation openings are located on the door panel of the processing equipment, and a conveying pipe is fixed to the door panel. The ventilation openings are connected to the air inlet of the conveying pipe via flexible hoses, and the air outlet of the conveying pipe is connected to flexible hoses to lead to areas requiring air conditioning cooling. The flexible hoses and flanges are sealed with hose clamps to ensure airtightness during air conditioning flow. In situations where space is limited, the connecting hoses at the air inlet and outlet of the conveying pipe are relatively short. When the door panel is rotated to open, the door panel may pull on the flexible hoses, making it impossible to open the door, or even breaking the flexible hose connected to the air outlet of the conveying pipe, affecting usability. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings.
[0023] like Figures 1-7 As shown, the refrigeration system includes a refrigeration device 1, a connecting pipe 2, and a refrigeration transmission device 3. The connecting pipe 2 connects the refrigeration device 1 and the refrigeration transmission device 3. The refrigeration device 1 can be an air conditioner, and the connecting pipe 2 can be a flexible hose.
[0024] The refrigeration transfer device 3 includes a vent 30 disposed on the rotating door panel 4, an air outlet 31 disposed on the sealing plate 5, and a converging air duct box 32 located between the sealing plate 5 and the rotating door panel 4. The vent 30, the converging air duct box 32 and the air outlet 31 form a flow channel for refrigerated gas to enter the interior of the processing equipment.
[0025] The ventilation opening 30 is equipped with a connector 34. The connector 34 includes a main body 340 adapted to be installed in the ventilation opening 30 and a flange ring 341 protruding outward from the middle of the main body 340. The connector 34 is fixed to the rotating door panel 4 by the flange ring 341. One end of the connector 34 is connected to the connecting pipe 2, and the other end is connected to the converging air duct box 32.
[0026] The ductwork box 32 includes an air inlet 320 corresponding to the ventilation opening 30 of the rotating door panel 4 and an air outlet 321 corresponding to the air supply outlet 31 of the sealing plate 5. The area of the air outlet 321 is not less than the area of the air inlet 320 to ensure a constant airflow. The area of the air supply outlet 31 of the sealing plate 5 is approximately equal to the area of the air outlet 321. The air inlet 320 of the duct junction box 32 is circular and matches the ventilation opening 30 of the rotating door panel 4. The air outlet 321 of the duct junction box 32 is rectangular. The front end of the duct junction box 32 where the air inlet 320 is located is higher than the rear end of the duct junction box 32 where the air outlet 321 is located. The side of the duct junction box 32 is approximately trapezoidal, which reduces the space occupied by the duct junction box 32. At the same time, the rectangular shape of the air outlet 321 of the duct junction box 32 can reduce the height of the rear end of the duct junction box 32, thereby reducing the height of the sealing plate at the rear end of the duct junction box 32 and reducing the space occupied.
[0027] To ensure the sealing effect of the refrigeration transmission device, a sealing gasket 6 is provided between the flange ring 341 and the rotating door plate 4, and between the rear end of the manifold box 32 and the sealing plate 5. The sealing gasket 6 can be made of rubber.
[0028] A sealing ring 7 is provided between the rotating door panel 4 and the converging air duct box 5. The sealing ring 7 is installed at one end of the connecting body 340 near the converging air duct box 32. The sealing ring 7 includes a fixing part 70 and an elastic sealing part 71. The fixing part 70 is installed on the connecting member 34, fixing the sealing ring to the connecting member 34. The elastic sealing part 71 is located between the rotating door panel 4 and the converging air duct box 32, sealing the gap between the rotating door panel 4 and the converging air duct box 32 through deformation. The fixing part 70 is U-shaped and inserts into the connecting body 340. The fixing part 70 has barbs 72 inside, which firmly secure the sealing ring 7 to the connecting body 340. The elastic sealing part 71 is a hollow annular shape that deforms during extrusion to achieve a seal. Preferably, the sealing ring 7 is made of EPDM (Ethylene Propylene Diene Monomer), which has good aging resistance and elasticity retention. The area of the air inlet 320 is slightly smaller than the area of the rotating door panel vent 30, allowing the sealing ring to be pressed tightly against the front end face of the corresponding manifold box 32. The elastic sealing part 71 is a hollow annular shape with an elastic deformation of up to 30%, ensuring that the sealing ring 7 fits tightly against the end face of the manifold box 32 and prevents leakage.
[0029] The refrigeration transmission device 3 is installed in a closed space of the processing equipment, separated from the processing area inside the processing equipment that needs to be refrigerated, and delivers refrigerated gas to the processing area through the air outlet 31 of the sealing plate 5.
[0030] To ensure the cleanliness of the gas entering the processing equipment, the refrigeration system preferably includes a gas filtration device 8. The gas output from the air outlet 31 is filtered to a Class 100 cleanroom level before being blown into the internal space of the processing equipment. The gas filtration device 8 can be an EFU (Equipment Fan Filter Unit).
[0031] When the rotating door panel 4 is opened, it rotates upwards, disengaging the sealing ring 7 of the connector from the front end face of the manifold box 32. When the rotating door panel 4 falls down to close and lock, the sealing ring 7 presses against the front end face of the manifold box 32, ensuring the airtightness of the refrigeration transmission device 3 and preventing leakage during the flow of refrigerated gas.
[0032] The refrigeration system can ensure airtightness in limited space, while eliminating the need for multiple connecting pipes and avoiding strain.
