Abstract

This utility model relates to the field of cabinet door technology and discloses a cabinet door structure with optimized heat dissipation function. It includes a cabinet body, a door on the outer wall of the cabinet body, an optimized heat dissipation mechanism on one side of the door, a temperature sensor fixedly mounted on the other side of the door, a limiting mechanism at the bottom of the cabinet body, and a heat dissipation vent at the top of the cabinet body. The temperature sensor at the rear of the door monitors the internal temperature of the cabinet. When the internal temperature is not high, cooling fans alone are sufficient for heat dissipation. When the internal temperature is too high, the airflow inside the cabinet is evenly distributed due to the multiple air vents, extending the equipment's lifespan. Furthermore, the uniform cool airflow allows the equipment to operate in a relatively stable temperature environment, reducing the impact of temperature fluctuations on equipment performance and improving the stability and reliability of equipment operation.

Description

Technical Field

[0001] This utility model relates to the field of cabinet door technology, specifically to a cabinet door structure with heat dissipation optimization function. Background Technology

[0002] In industrial production, there are usually many electrical devices in the production site, so it is necessary to use a cabinet to store the switches or components of the control circuits in a centralized manner.

[0003] Existing server racks typically dissipate heat naturally through ventilation holes or by using cooling fans during use. When the internal temperature of the rack is too high, the heat dissipation effect is slow, and the airflow generated by the fan may be unevenly distributed inside the rack, which can easily cause the components inside the rack to overheat and malfunction or be damaged. Therefore, we have introduced a new rack door structure with optimized heat dissipation function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cabinet door structure with optimized heat dissipation, which has the advantages of good heat dissipation and stability, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a cabinet door structure with heat dissipation optimization function, including a cabinet body, a door body on the outer wall of the cabinet body, a heat dissipation optimization mechanism on one side of the door body, a temperature sensor fixedly mounted on the other side of the door body, a limiting mechanism at the bottom of the cabinet body, a heat dissipation vent at the top of the cabinet body, a connecting frame fixedly mounted on the top of the cabinet body, a cooling fan and a dustproof net fixedly mounted on the inner wall of the connecting frame, and electronic components fixedly mounted on the inner wall of the cabinet body.

[0006] As a preferred technical solution of this utility model: the optimized heat dissipation mechanism includes a cooler, an air inlet pipe is fixedly installed at the output end of the cooler, an air collection box is fixedly installed at the end of the air inlet pipe away from the cooler, an air outlet is provided at the end of the air collection box away from the cooler, and a filter screen is fixedly installed on the inner wall of the air outlet.

[0007] As a preferred technical solution of this utility model: the limiting mechanism includes a connecting plate, the inner wall of the connecting plate is provided with a through groove, the bottom of the connecting plate is rotatably connected with a universal wheel, the outer wall of the connecting plate is provided with a cylinder, and the outer wall of the cylinder is provided with an anti-slip pad.

[0008] As a preferred technical solution of this utility model: the dustproof net is located above the cooling fan, the air collection box is connected to the inner wall of the air inlet pipe, the air cooler and the air collection box are both fixedly assembled with the door, the temperature sensor is located above the door, and the heat dissipation vent is connected to the inner wall of the cabinet.

[0009] As a preferred technical solution of this utility model: the cylinder is installed at the lower end of the cabinet, the anti-slip pad is located below the connecting plate, and the outer surface of the anti-slip pad does not contact the caster wheel.

[0010] As a preferred technical solution of this utility model: there are four limiting mechanisms, and the four limiting mechanisms are respectively located at the bottom of the cabinet. There are several air outlets and filters, and several air outlets and filters are fixedly assembled with the door.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This cabinet door structure with optimized heat dissipation monitors the internal temperature of the cabinet through a temperature sensor at the rear of the door. When the internal temperature is not high, the cooling fan alone is sufficient for heat dissipation. When the internal temperature is too high, the air cooler is activated, sending cool air through the air inlet duct into the air collection box. The cool air in the air collection box is then sent into the cabinet through several air outlets for cooling. Since the air outlets are evenly distributed vertically, the airflow inside the cabinet is uniform, ensuring that all equipment or components inside the cabinet are effectively cooled, avoiding local overheating, thereby improving overall heat dissipation efficiency, extending the service life of the equipment, and the uniform airflow allows the equipment to operate in a relatively stable temperature environment, reducing the impact of temperature fluctuations on equipment performance and improving the stability and reliability of equipment operation.

[0012] 2. This rack door structure with optimized heat dissipation features a limiting mechanism. By activating four cylinders, each cylinder moves one of the four anti-slip pads upwards, bringing the four casters to the ground. The casters allow for easy movement and adjustment of the entire rack. The four cylinders also move the four anti-slip pads downwards, ensuring they are in close contact with the ground. This keeps the rack fixed in place, improving its stability during use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 A cabinet door structure with heat dissipation optimization function includes a cabinet body 1, a door body 2 on the outer wall of the cabinet body 1, a heat dissipation optimization mechanism 3 on one side of the door body 2, a temperature sensor 4 fixedly mounted on the other side of the door body 2, a limiting mechanism 5 at the bottom of the cabinet body 1, a heat dissipation vent 6 at the top of the cabinet body 1, a connecting frame 7 fixedly mounted on the top of the cabinet body 1, a cooling fan 8 and a dustproof net 9 fixedly mounted on the inner wall of the connecting frame 7, and electronic components 10 fixedly mounted on the inner wall of the cabinet body 1. In the above structure, the electronic components 10 are composed of control circuit switches, relays, contactors, and frequency converters. These components are fixed to the two side uprights or the middle horizontal support plate inside the cabinet 1 by standardized guide rails and are distributed in layers along the height of the cabinet 1. The connecting frame 7 is fixed to the middle of the upper part of the cabinet 1. The cooling fan 8 inside it is directly connected to the internal space of the cabinet 1. The installation area of ​​the electronic components 10 is located directly below and on both sides of the connecting frame 7, ensuring that the cooling fan 8 can effectively extract the hot air generated by the electronic components 10. At the same time, the heat dissipation vents 6 on the left and right sides of the upper part of the cabinet 1 complement the connecting frame 7, covering the upper edge area of ​​the cabinet 1, and together with the cooling fan 8 in the middle, they form an exhaust channel to meet the heat dissipation requirements of the internal electronic components 10.

[0017] In a preferred embodiment: the optimized heat dissipation mechanism 3 includes a cooler 31, an air inlet pipe 32 is fixedly installed at the output end of the cooler 31, an air collection box 33 is fixedly installed at the end of the air inlet pipe 32 away from the cooler 31, an air outlet 34 is provided at the end of the air collection box 33 away from the cooler 31, and a filter screen 35 is fixedly installed on the inner wall of the air outlet 34. In the above structure, the cooler 31 of the optimized heat dissipation mechanism 3 generates cool air, which is delivered to the air collection box 33 at the rear end of the door 2 through the air inlet duct 32. Then, it is laterally delivered into the cabinet 1 through several air outlets 34 distributed at equal intervals. Since the air outlets 34 are evenly distributed along the height of the door 2, the cool air can directly cover the electronic components 10 inside the cabinet 1 from bottom to top. After the cool air absorbs heat on the surface of the electronic components 10, the resulting hot air flows upward due to its reduced density. Part of it is naturally discharged through the heat dissipation vents 6 on the left and right sides of the upper part of the cabinet 1, and the other part is absorbed by the connecting frame 7. Cooling fan 8 exhausts air from outside cabinet 1, while cool air is introduced from the rear of door 2 and hot air is exhausted from the top of cabinet 1, forming a closed-loop airflow that covers all areas inside cabinet 1. This ensures that all electronic components 10 are effectively cooled. When temperature sensor 4 detects that the internal temperature of cabinet 1 is low, the cooling requirements can be met simply by the natural convection between cooling fan 8 in connecting frame 7 and the upper heat dissipation vent 6. When the temperature is too high, air cooler 31 starts up, enhancing the input of cool air through evenly distributed air outlets 34. Combined with the upper exhaust structure, this improves cooling efficiency and prevents local overheating.

[0018] In a preferred embodiment: the limiting mechanism 5 includes a connecting plate 51, the inner wall of the connecting plate 51 is provided with a through groove 53, the bottom of the connecting plate 51 is rotatably connected with a caster wheel 52, the outer wall of the connecting plate 51 is provided with a cylinder 54, and the outer wall of the cylinder 54 is provided with an anti-slip pad 55. In the above structure, by activating four cylinders 54, the four cylinders 54 move the four anti-slip pads 55 upwards, so that the four casters 52 touch the ground. The casters 52 make it easy to move and adjust the position of the entire cabinet. The four cylinders 54 move the four anti-slip pads 55 downwards, so that the four anti-slip pads 55 are in close contact with the ground, so that the entire cabinet can be fixed in place at the place of use, which can improve the stability of the entire cabinet during use.

[0019] In a preferred embodiment: the dustproof net 9 is located above the cooling fan 8, the air collection box 33 is connected to the inner wall of the air inlet pipe 32, the air cooler 31 and the air collection box 33 are both fixedly assembled with the door 2, the temperature sensor 4 is located above the door 2, and the heat dissipation vent 6 is connected to the inner wall of the cabinet 1. In the above structure, dust is blocked by the dustproof net 9 to prevent dust from affecting the cooling fan 8. The air inlet pipe 32 connects the air cooler 31 and the air collection box 33. The door 2 limits the optimized heat dissipation mechanism 3 to prevent it from falling off during use. The temperature sensor 4 is located above the door 2 to improve its monitoring effect. The heat dissipation vent 6 provides basic heat dissipation for the interior of the cabinet 1.

[0020] In a preferred embodiment: the cylinder 54 is installed at the lower end of the cabinet 1, the anti-slip pad 55 is located below the connecting plate 51, and the outer surface of the anti-slip pad 55 does not contact the caster wheel 52; In the above structure, the cabinet 1 is used to limit the limiting mechanism 5, making the limiting mechanism 5 more stable during use. The anti-slip foot pads 55 are used to support the connecting plate 51, so that the connecting plate 51 will not fall off when placed.

[0021] In a preferred embodiment: there are four limiting mechanisms 5, and the four limiting mechanisms 5 are respectively located at the bottom of the cabinet 1. There are several air outlets 34 and filters 35, and several air outlets 34 and filters 35 are fixedly assembled with the door 2. In the above structure, four limiting mechanisms 5 are used to support the cabinet 1, making the cabinet 1 more stable when placed or moved. Several air outlets 34 and filters 35 are used to cool down the temperature inside the cabinet 1 more quickly.

[0022] Working Principle: During operation, the temperature sensor 4 located behind the door 2 monitors the temperature inside the cabinet 1 in real time. When the internal temperature of the cabinet 1 is low, the cooling fan 8 alone is sufficient for heat dissipation. However, once the internal temperature of the cabinet 1 rises to a higher level, the air cooler 31 is activated for efficient heat dissipation. The air cooler 31 delivers cool air to the air collection box 33 through the air inlet duct 32. The cool air in the air collection box 33 is evenly distributed into the interior of the cabinet 1 through multiple air outlets 34, achieving all-round cooling and optimizing the heat dissipation function. It is worth noting that the several air outlets 34 are distributed at equal vertical distances to ensure that the airflow inside the cabinet 1 is evenly distributed. In this way, the equipment or components in every corner of the cabinet 1 can be fully cooled. This effectively avoids localized overheating, thereby greatly improving overall heat dissipation efficiency and further extending the equipment's lifespan. In addition, the evenly distributed cool airflow provides a relatively stable operating environment for the equipment, reducing the impact of temperature fluctuations on equipment performance, thus improving the stability and reliability of equipment operation. When it is necessary to move or adjust the position of the cabinet, it can be operated by activating four cylinders 54. The four cylinders 54 will drive the four anti-slip pads 55 upward, so that the four casters 52 contact the ground, thus facilitating the movement and adjustment of the entire cabinet. When it is necessary to fix the position of the cabinet, the four cylinders 54 will move the four anti-slip pads 55 downward, so that they are in close contact with the ground. In this way, the entire cabinet can be stably fixed at the place of use, improving the stability during use.
