Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber production equipment, and particularly relates to a composite heat dissipation system for a high-protection IO box in a carbon fiber environment. Background Technique

[0002] The on-site IO box, as a transit slave station box for collecting on-site instrument data and communicating with the PLC, its heat dissipation performance directly affects the equipment performance and system stability. When the modules in the IO box run continuously for a long time, under the premise of requiring a high protection level, the single air-cooled heat dissipation method of introducing compressed air is slightly insufficient in heat dissipation effect when facing a high-load IO box and cannot meet the heat dissipation requirements of the high-protection IO box. If the air-cooled heat dissipation method of additionally installing multi-piece radiators and introducing compressed air is adopted, perhaps the heat dissipation effect can be improved, but the problem with this solution is that the on-site IO box is small in volume, small in capacity, and has a large number of internal components, and it is not easy to arrange the space for installing the radiator.

The composite heat dissipation system is embedded in the IO box body. The composite heat dissipation system includes a mounting plate. Prefabricated riveting studs are arranged on the front end face of the mounting plate. A circulating water cavity is arranged on the rear end face of the mounting plate. An inlet and an outlet are arranged at the top of the circulating water cavity. A plurality of baffle plates are arranged in the circulating water cavity.

[0014] The technical solutions of the present utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0015] Embodiment: A composite heat dissipation system for a high-protection IO box in a carbon fiber environment, as Figures 1 - 3As shown in the figure, it includes an IO box body 1 and a composite heat dissipation system 2. The composite heat dissipation system 2 is embedded in the IO box body 1. The composite heat dissipation system 2 includes a mounting plate 3. On the front end face of the mounting plate 3, there are prefabricated riveting studs 4. On the rear end face of the mounting plate 3, there is a circulating water cavity 5. At the top of the circulating water cavity 5, there is an inlet 6 and an outlet 7. Inside the circulating water cavity 5, there are multiple baffle guide plates 8. At the upper and lower ends of the multiple baffle guide plates 8, there is a sealing plate 9 for sealing the upper and lower ends of the multiple baffle guide plates 8. The multiple baffle guide plates 8 and the sealing plates 9 at the upper and lower ends form multiple circulating water inlet channels 10. At the positions corresponding to each circulating water inlet channel 10 on the two sealing plates 9, there is an inlet and outlet port 11. On the upper sealing plate 9, there is a shunt box 12. Between the shunt box 12 and the inlet 6 of the circulating water cavity 5, there is a connecting water pipe 13. The multiple circulating water inlet channels 10 and the inner cavity of the circulating water cavity 5 outside the shunt box 12 form a circulating water outlet channel 14.

[0016] At the upper and lower ends of the IO box body 1, there is a sealing plate 15. On one of the sealing plates 15, there is a water inlet leading-out pipe 16 and a water outlet leading-out pipe 17; on the other sealing plate 15, there is a silencer 18. On the left and right side surfaces of the IO box body 1, there are multiple through-wall plates 19. On one side of the through-wall plates 19, there is an air pipe connection port 20.

[0017] Principle of the present utility model: Connect a compressed air pipe through the through-wall plate 19 or an opening gland on the side of the IO box in the same way as connecting the cables into the IO box. Additionally, install a muffler at a suitable position by opening a hole on the through-wall plate 19 or the spare sealing plate 15 on the other side of the box body to form an air path. Just ensure that the air outlet of the air pipe connected into the IO box is unobstructed and the air can be normally introduced into the box. Compressed air is introduced into the IO box through the air pipe, creating a positive pressure inside the box. Then, the air is blown out through the muffler to carry away the heat in the atmosphere inside the box. Connect the air pipe through a suitable through-wall plate 19 or a gland of corresponding size to maintain a positive pressure inside the box, which can ensure that carbon filaments in the external environment do not enter the box.

[0018] The water inlet leading-out pipe 16 and the water outlet leading-out pipe 17 on the IO box are respectively connected to the inlet 6 and an outlet 7 of the circulating water cavity 5. Circulating water is introduced into the shunt box 12 through the water inlet leading-out pipe 16, enters multiple circulating water inlet channels 10 through the shunt box 12, exchanges heat with the back surface of the mounting plate 3, and finally enters the circulating water outlet channel 14 through the inlet and outlet ports 11 on the bottom sealing plate 9 and is led out through the water outlet leading-out pipe 17 to complete the cycle; the introduced cooling water is preferably constant-temperature cooling water. For an IO box with a size of 400mm * 800mm * 180mm, a water inlet pressure above 0.8MPa can have an obvious cooling effect.

[0019] In order for the electrical component to be in close contact with the mounting plate 3, it is installed by using a prefabricated rivet stud 4 on the front end face of the mounting plate 3. In practical applications, the position of the prefabricated rivet stud 4 is opened according to actual needs.

[0020] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention shall be considered to fall within the protection scope of the present invention.
