Description

A cooling device for automatic production control

Technical field

The invention belongs to the field of automatic control equipment, especially a heat dissipation device for automatic production control.

Background technique

Automation control technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and homes. The use of automated control can not only liberate people from heavy physical labor, partial mental labor, and harsh and dangerous working environments, but also expand human organ functions and greatly improve labor productivity.

Automation control technology is commonly used in industrial production in various factories. Such devices need to work stably for a long time, so a stable heat dissipation mechanism needs to be designed.

At present, in this type of automated control equipment, the common and customary heat dissipation mechanism mostly uses fans to exchange heat between the inside and outside of the control equipment. This heat exchange method has great shortcomings, such as: When dissipating heat, the cold air and the hot air inside the equipment are disordered in the flow process. After the cold air enters, it flows in the direction of flow and simply squeezes the hot air out. This only removes the components in the control device. The heat generated is transferred away, and there is almost no heat exchange action.

Therefore, we propose an automated production control device to solve the above technical problems existing in the existing control device.

Further, a motor 201 is installed in the inner cavity of the exhaust box 2. A fan blade structure 202 is mounted on the output shaft of the motor 201. An exhaust port 203 is provided on the side of the exhaust box 2. The bottom of the exhaust box 2 is in contact with the control unit. The inner cavities of box 1 are connected.

Further, the air intake mechanism 10 includes an upper air pipe 101 and a lower air pipe 102. The lower air pipe 102 is an internally threaded pipe, the upper air pipe 101 is an externally threaded pipe, and the lower air pipe 102 is threadedly installed on the outside of the upper air pipe 101.

Further, the top of the upper air pipe 101 penetrates the bottom of the sealed box 4 and extends to the inner cavity of the sealed box 4 , and the bottom of the lower air pipe 102 penetrates the control box 1 and extends to the outside of the bottom of the control box 1 .

Further, the guide piece 9 is a metal sheet, and the right side of the guide piece 9 is curved, and the bending direction is obliquely downward. The thickness of the guide piece 9 is less than the height of the air duct 7 , and the guide piece 9 is inserted into the inner cavity of the sealed box 4 Parts gradually increase from bottom to top. Specifically, each guide piece 9 has the same size and shape, but each guide piece 9 extends into the sealing box 4 from the bottom up in the inner cavity of the sealing box 4. The lengths are different, so that the area distributed in the sealed box increases from bottom to top.

In this embodiment, as shown in Figures 1 to 6, when using this control device, various electrical components used by the control device are directly installed on the component rack 6, and as much as possible, one of the components is The side is close to the right side of the shelf plate 5. Start the motor 201, and the output shaft of the motor 201 drives the fan blade structure 202 on it to rotate, sucking the internal air upward from the right side of the inner cavity of the control box 1. The occurrence of this air suction action can make the sealed box 4 Suction will also be generated in the inner cavity, and then air will be sucked from the bottom outside the control box 1 through the air intake mechanism 10. The air sucked into the control box 1 here comes from a position close to the ground, so it can be completely guaranteed. The temperature of the air entering the interior of the control box 1 is relatively low and can play a role in heat exchange. When the cold air enters the sealed box 4 through the air inlet mechanism 10, it will continue to flow upward. When flowing upward, part of the cold air will be blocked by the guide plate 9 installed from bottom to top. The blocking here is Each guide piece 9 will have different depths extending into the sealed box 4. Therefore, it can be ensured that each guide piece 9 can block a part of the cold air. The cold air blocked by the guide plate 9 will continue to flow along the lower surface of the inclined guide plate 9, and then flow out of the sealed box 4 from the air duct 7. With the curved guide plate 9 on the right end, the cold air can directly hit the On the side of the shelf plate 5, the heat generated by the work of the components absorbed by the shelf plate 5 is directly exchanged, directly cooling it, and then continues to flow downward along the side of the shelf plate 5, and finally passes through the bottom of the shelf plate 5 It enters the space on the right side of the control box 1 and is finally discharged from the exhaust box 2.

In this embodiment, as shown in Figures 3, 4 and 7, based on Embodiment 1, that is, after the cold air drawn into the inner cavity of the control box 1 enters the space on the right side of the control box 1 from the bottom of the shelf plate 5 , it will flow from bottom to top. Due to the restriction and obstruction of the component rack 6, the rising airflow can only enter from the gap on the left side of the lower panel 63, and then flow along the channel between the lower panel 63 and the middle panel, and then flow It enters the passage between the upper panel 61 and the middle panel 62 from the gap on the right side of the middle panel 62, and finally flows out from the gap on the left side of the upper panel 61. When the cold air flows from bottom to top, it needs to be installed in each component rack. The above action occurs on 6. When the cold air flows in the U-shaped channel, it is fully in contact with the component rack 6. In this way, the flowing cold air can make full use of its heat for heat exchange, and the U-shaped channel also The time that the cold air stays in the component rack 6 can be increased to fully utilize the heat of the cold air.

The coarse filter here can remove some larger blockages. Filtered down to avoid poor suction, the cold air entering the lower air pipe 102 flows upward and directly hits the filter box 106 for secondary filtration and drying to prevent dust or water vapor from entering the control device and damaging electrical appliances. When the filter box 106 is installed, the cold air will also hit the scraper 105, driving the scraper 105 to rotate. When the scraper 105 rotates, the dust particles filtered by the filter box 106 can be scraped off. , to ensure the normal use of the filter box 106.
