Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, and in particular to a control cabinet. Background Art

[0002] With the rapid development of industry and technology, the electronic equipment in the control cabinet is constantly upgraded and integrated, and the heat generated by the electronic equipment during operation is also increasing. If the heat cannot be effectively dissipated, the excessive temperature will cause the performance of the electronic components to decline, shorten their lifespan, and even cause failures, thus affecting the normal operation of the entire system.

[0003] Especially the robot control cabinet. As the number of robots deployed in factories increases, the installation density of robots continues to increase, and the application scenarios become more and more complex. The robot control cabinet needs to be miniaturized and highly protected to adapt to small spaces and harsh environments to achieve flexible deployment. This puts higher requirements on heat dissipation to ensure that the equipment can still maintain good performance and reliability under various harsh environments and high-load operating conditions. Summary of the invention

[0004] In view of this, the present invention provides a control cabinet to solve the problem that miniaturization of the control cabinet and high heat dissipation requirements cannot be achieved at the same time.

[0011] Beneficial effects: the accommodating chamber inside the cabinet is divided into a first chamber and a second chamber by an isolation plate. The high-heat generating components and the low-heat generating components can be separated by the first chamber and the second chamber, thereby realizing centralized heat isolation, preventing mutual interference between the high-heat generating components and the low-heat generating components, and improving heat dissipation efficiency. The high-heat generating components enhance the heat dissipation effect through the heat dissipation structure in the first chamber. The low-heat generating components themselves generate less heat and can directly dissipate heat through conduction through the cabinet. Both the first chamber and the second chamber can have good heat dissipation effects. Moreover, since the accommodating chamber is divided into the first chamber and the second chamber only by an isolation plate, the isolation plate occupies a small space and makes reasonable use of the space of the accommodating chamber, thereby reducing the number and size of the heat dissipation structures, so that the control cabinet as a whole can be miniaturized.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0056] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0057] According to an embodiment of the present invention, a control cabinet is provided, comprising a cabinet body 1, an isolation plate 2, a high-heat-generating component 3, a low-heat-generating component 4 and a heat dissipation structure; a accommodating cavity is provided inside the cabinet body 1; the isolation plate 2 is connected to the accommodating cavity and divides the accommodating cavity into a first chamber and a second chamber; the high-heat-generating component 3 is arranged in the first chamber; the low-heat-generating component 4 is arranged in the second chamber; and the heat dissipation structure is arranged in the first chamber.

[0058] The accommodating cavity inside the cabinet 1 is divided into a first cavity and a second cavity by an isolation plate 2. The high-heat generating component 3 and the low-heat generating component 4 can be separated by the first cavity and the second cavity, so as to realize concentrated heat isolation, prevent mutual interference between the high-heat generating component 3 and the low-heat generating component 4, and improve the heat dissipation efficiency; the high-heat generating component 3 enhances the heat dissipation effect through the heat dissipation structure in the first cavity, and the low-heat generating component 4 itself generates less heat and can directly conduct heat through the cabinet 1, so that the first cavity and the second cavity can both have good heat dissipation effect; and, since the accommodating cavity is divided into the first cavity and the second cavity only by the isolation plate 2, the isolation plate 2 occupies a small space and makes reasonable use of the space of the accommodating cavity, thereby reducing the number and size of the heat dissipation structure, so that the control cabinet as a whole can achieve the purpose of miniaturization.

[0059] In a preferred embodiment, the first chamber can be located at the bottom of the second chamber. Such a configuration can not only lower the position of the heat dissipation outlet to avoid discomfort to the operator caused by hot air, but also increase the heat dissipation effect of the first chamber with the help of the bottom wall of the cabinet body 1 of the control cabinet, and can also ensure that the side walls and the top wall of the cabinet body 1 become the heat exchange medium of the second chamber, thereby enhancing the heat dissipation effect of the second chamber.

[0060] In this embodiment, the high-heat generating component 3 refers to a component that generates a high amount of heat when it is running, or a heat dissipation component or a heat conducting component that conducts or dissipates the heat of a component that generates a high amount of heat when it is running. The high-heat generating component 3 needs to be radiated by a heat dissipation structure. For example, in this embodiment, the high-heat generating component 3 may include a heat sink 31 of a driver, and may also include a brake resistor 32.

[0061] In this embodiment, the low-heat component 4 refers to a component that generates relatively low heat during its own operation. The heat generated by the low-heat component 4 usually has little impact on other components around it. The low-heat component 4 can achieve a good heat dissipation effect by heat conduction through the cabinet 1. For example, in this embodiment, the low-heat component 4 may include a transformer, a filter, an air switch, a main controller, a safety controller, a contactor, a relay, a terminal block and a 24V switching power supply lamp component. Among them, some components that generate relatively high heat during their own operation, such as a driver, when connected to the radiator 31, the heat generated can be conducted to the radiator 31 for heat dissipation. At this time, the driver can be a low-heat component 4 and the radiator 31 can be a high-heat component 3.

[0062] In one embodiment, the control cabinet also includes at least one support plate 6 connected to the isolation plate 2, at least one of the support plates 6 is arranged in the first chamber, and the first chamber is divided into at least two heat dissipation chambers, each of the heat dissipation chambers is provided with the high-heat generating component 3 and the heat dissipation structure.

[0063] By setting the support plate 6, the first chamber can also be divided into different heat dissipation chambers, and then the high-heat-generating components 3 can be individually cooled through the heat dissipation chambers and the heat dissipation structures set therein, avoiding mutual interference between the high-heat-generating components 3, so that each high-heat-generating component 3 can obtain a better heat dissipation effect.

[0064] In a specific embodiment, one high-heat generating component 3 and a group of heat dissipation structures may be disposed in each heat dissipation chamber, or at least two high-heat generating components 3 and at least two groups of heat dissipation structures may be disposed.

[0066] The heat sink 31 is connected to the components in the second chamber by thermal conduction, and the heat of the components in the second chamber can be transferred to the first heat dissipation chamber 11. Under the guidance of the first heat dissipation fan 51, the outside air enters the first heat dissipation chamber 11 through the first air inlet 12, and when passing through the heat sink 31, the heat conducted on the heat sink 31 can be taken away and discharged from the first air outlet 13 to achieve heat dissipation. In addition, the components in the second chamber can also be easily connected to other components in the second chamber.

[0067] In a specific embodiment, the component located in the second chamber and thermally connected to the heat sink 31 may be a driver. Most of the heat of the driver is conducted to the first heat dissipation chamber 11 through the heat sink 31, so that the driver located in the second chamber generates less heat in the second chamber and can become a low-heat generating component 4.

[0069] The setting of the guide plate 7 guides the wind direction on the air outlet path between the first air inlet 12 and the first air outlet 13, so that the heat dissipation wind passing through the heat dissipation fins can blow along the length extension direction of the heat dissipation fins, ensuring that the wind resistance passing through the heat dissipation fins of the radiator 31 is small, the noise is small, and the heat dissipation effect is better.

The wind shield 8 can block and guide the heat dissipation wind close to the bottom wall of the cabinet 1 so that the heat dissipation wind can be concentrated to blow toward the radiator 31; it can also limit the two guide plates 7 and increase the strength of the two guide plates 7.

[0076] In a specific embodiment, the guide plate 7 includes a plate body 71, a first connecting strip 72 and a second connecting strip 73. In the width direction of the plate body 71, the first connecting strip 72 and the second connecting strip 73 are respectively connected to both sides of the plate body 71. The first connecting strip 72 is provided with a connecting hole 721, and the connecting hole 721 is detachably connected to the bottom wall of the cabinet 1 through a fastener.

[0098] Calculate the required air volume: Q(m 3 / min)=0.05×6000 / 35×1.3=9.75(m 3 / min).

[0099] Converted to Q (CFM) = 9.75 x 35.315 = 345 (CFM).

[0100] A fan with a size of (60mmx60mm) is selected based on the required air volume. The air volume of a fan with a size of 60mmx60mmx38mm is: 58.62 (CFM). If the air volume is below 58.62 (CFM), 6 fans with a size of 60mmx60mmx38mm (6x58.62=351.72 (CFM)) are required to meet the use requirements.

[0101] Therefore, in a specific embodiment, there may be four first cooling fans 51, which are fans with a size of 60 mm*60 mm*38 mm. There may be two second cooling fans 52, which are fans with a size of 60 mm*60 mm*38 mm.

[0102] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
