Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment for electronic components, specifically a multi-fan heat dissipation type electrical box structure. Background Technology

[0002] In modern industrial automation, new energy storage, data centers and other fields, electrical boxes are the core carriers for the operation of electrical equipment. The internal electronic components are becoming increasingly dense and under high loads. Heat dissipation issues directly affect the stability of the equipment and the lifespan of the components.

[0003] Most existing electrical enclosures still use a distributed fan layout or a single fan design. Distributed fans, lacking a systematic layout, struggle to create a unified and efficient airflow field; single fans, limited by their coverage area, cannot quickly handle large-area heat-generating scenarios. This results in low heat dissipation efficiency and poor temperature control in applications involving high-heat-generating equipment such as server racks and high-frequency transformers. Furthermore, in existing enclosures, the airflow generated by the fans often diffuses haphazardly, resulting in significant energy loss upon collision with the enclosure and failing to precisely direct airflow to core heat-generating components. This crude heat dissipation method wastes resources and fails to guarantee effective cooling. Utility Model Content

[0004] The purpose of this invention is to provide a multi-fan heat dissipation type electrical box structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-fan heat dissipation type electrical box structure, including an electrical box shell, comprising,

[0006] Multiple cooling fans are connected to one side of the electrical box housing and are distributed in a linear array with equal spacing along the height of the electrical box housing;

[0007] A deflector plate, installed inside the electrical box housing, is used to guide airflow. A mounting plate is connected to one side of the top of the deflector plate for mounting electronic components. The deflector plate and the mounting plate together form an "L"-shaped airflow guide.

[0008] Furthermore, a telescopic slide plate is slidably connected inside the electrical box housing, and the guide plate is connected to the top of the telescopic slide plate.

[0009] Furthermore, a guide rail is connected inside the electrical box housing, and slide rails are connected to both sides of the telescopic slide plate, with the slide rails slidably connected inside the guide rail.

[0010] Furthermore, a vertical support plate is connected to the top of the telescopic sliding plate, and the top of the vertical support plate is connected to the mounting plate.

[0011] Furthermore, a handle is connected to the top of the telescopic sliding plate, and the vertical cross-section of the handle is trapezoidal.

[0012] Furthermore, the top of the mounting plate has multiple mounting holes, which are distributed in a rectangular array at equal intervals.

[0013] Furthermore, the rear side of the electrical box housing is connected to a plurality of symmetrical connecting plates for mounting the electrical box housing.

[0014] Furthermore, the handle is fitted with an anti-slip sleeve, which is made of rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: Multiple cooling fans are linearly arrayed, which can quickly bring a large amount of cold air from the outside into the electrical box. With the help of the guide plate to change the airflow direction, the cold air can be evenly covered inside the electrical box. The airflow channel constructed by the "L"-shaped structure increases the contact between the airflow and the electronic components, enhances convective heat transfer, efficiently removes heat, and ensures the stable operation of the electronic components. The guide plate can accurately guide the airflow to the heat-generating area and adjust the airflow path according to the distribution of electronic components to avoid airflow waste, effectively solve the problem of local overheating, and improve the overall heat dissipation efficiency. The telescopic sliding plate can drive the guide plate and the mounting plate to slide, making the electronic components on the mounting plate easier to access, facilitating maintenance operations such as inspection, repair and replacement, and reducing maintenance time and costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a multi-fan heat dissipation type electrical box structure, including an electrical box shell 1, comprising,

[0024] Multiple cooling fans 2 are connected to one side of the electrical box housing 1 and are distributed in a linear array with equal spacing along the height direction of the electrical box housing 1;

[0025] The air guide plate 31 is installed inside the electrical box housing 1 and is used to guide the airflow. A mounting plate 32 is connected to one side of the top of the air guide plate 31 for mounting electronic components. The air guide plate 31 and the mounting plate 32 together form an "L"-shaped airflow guide.

[0026] It should be noted that an air outlet is provided on the top of the electrical box housing 1.

[0027] In practice, multiple cooling fans 2 are arranged in a linear array at equal intervals on one side of the electrical enclosure 1. When the electronic components inside the enclosure 1 are running, the heat generated by the components raises the internal temperature. The cooling fans 2 then activate, drawing in cool air from the outside. The cool air injected by the cooling fans 2 first impacts the guide plate 31 inside the enclosure 1, changing the direction of the originally horizontal airflow. As the airflow hits the guide plate 31, it is guided and directed along its surface to various areas inside the enclosure 1 by the obstruction and guidance of the guide plate 31. The mounting plate 32 connected to the top of the guide plate 31 is used to mount the electronic components. After being guided by the guide plate 31, some of the airflow directly blows onto the surface of the electronic components on the mounting plate 32. Simultaneously, the "L"-shaped structure formed by the mounting plate 32 and the guide plate 31 creates a relatively closed airflow channel inside the enclosure. When the airflow flows within this channel, it creates turbulence around the electronic components, increasing the contact area and time between the airflow and the electronic components, thus enhancing the convective heat transfer effect and quickly removing the heat dissipated by the electronic components.

[0028] See Figure 2 A telescopic slide plate 5 is slidably connected inside the electrical box housing 1, and a guide plate 31 is connected to the top of the telescopic slide plate 5.

[0029] In practice, the telescopic slide plate 5 can drive the guide plate 31 and the mounting plate 32 to slide, which facilitates the maintenance of electronic components installed on the mounting plate 32.

[0030] See Figure 4 The electrical box housing 1 is connected to a guide rail 6, and the telescopic slide plate 5 is connected to slide rails 7 on both sides, with the slide rails 7 slidably connected inside the guide rail 6.

[0031] In practice, the guide rail 6 and slide rail 7 can be used together to limit and guide the sliding of the telescopic slide plate 5, further improving the stability of the telescopic slide plate 5 during the sliding process.

[0032] refer to Figure 2 The top of the telescopic sliding plate 5 is connected to a vertical support plate 4, and the top of the vertical support plate 4 is connected to the mounting plate 32.

[0033] In practice, the vertical support plate 4 improves the stability of the mounting plate 32 during use and can provide a certain support force for the mounting plate 32.

[0034] See Figure 4 The top of the telescopic sliding plate 5 is connected to a handle 8, and the vertical cross-section of the handle 8 is trapezoidal.

[0035] In practice, the handle 8 is designed to allow users to apply force to pull the telescopic slide plate 5 and slide it.

[0036] refer to Figure 1 The top of the mounting plate 32 has multiple mounting holes 9, which are distributed in a rectangular array at equal intervals.

[0037] In practice, the mounting hole 9 facilitates the installation of electronic components.

[0038] The rear side of the electrical box housing 1 is connected to multiple symmetrical connecting plates for mounting the electrical box housing 1.

[0039] In practice, the connecting plate facilitates the installation of the electrical box housing 1 on the wall.

[0040] The handle 8 is fitted with an anti-slip sleeve, which is made of rubber.

[0041] In practice, the anti-slip sleeve increases the friction of the handle 8, making it easier for users to pull the handle 8.

[0042] Working Principle: Multiple cooling fans 2 are linearly arrayed at equal intervals on one side of the electrical enclosure 1. When the electronic components inside the enclosure 1 are running, the heat generated by the components raises the internal temperature. The cooling fans 2 then activate, drawing in cool outside air. The cool air injected by the cooling fans 2 first impacts the guide plate 31 inside the enclosure 1, changing the direction of the originally horizontal airflow. As the airflow hits the guide plate 31, it is guided along its surface by the obstruction and direction of the guide plate 31, flowing to various areas inside the enclosure 1. The mounting plate 32 connected to the top of the guide plate 31 is used to mount the electronic components. After being guided by the guide plate 31, some of the airflow directly blows onto the surface of the electronic components on the mounting plate 32. Simultaneously, the "L"-shaped structure formed by the mounting plate 32 and the guide plate 31 creates a relatively closed airflow channel inside the enclosure. When the airflow flows in this channel, it creates turbulence around the electronic components, increasing the contact area and time between the airflow and the electronic components, enhancing the convective heat transfer effect, and thus quickly removing the heat dissipated by the electronic components.

[0043] The telescopic slide plate 5 can drive the guide plate 31 and the mounting plate 32 to slide, which facilitates the maintenance of electronic components installed on the mounting plate 32.
