Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a heat flow guided heat dissipation power distribution cabinet. Background Technology
[0002] A distribution cabinet is an electrical device used for centralized control and distribution of electrical energy. It mainly consists of a cabinet, switching devices, protective devices, measuring instruments, busbars, etc. During the operation of the distribution cabinet, the internal electrical components will continuously generate heat. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the cabinet will be too high, affecting the performance and lifespan of the electrical components, and even causing safety hazards.
[0003] Traditional heat dissipation methods for electrical distribution cabinets, such as natural heat dissipation, rely on natural air convection, which is inefficient. Air-cooled heat dissipation methods often fail to fully consider the direction of heat flow and cannot guide the heat flow in a targeted manner, resulting in inefficient heat dissipation and the inability to dissipate internal heat in a timely manner.
[0004] To address these issues, those skilled in the art have proposed a heat flow-guided heat dissipation distribution cabinet. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] In view of the problem that the above-mentioned or existing technologies cannot guide heat flow in a targeted manner, resulting in inefficient heat dissipation, this utility model is proposed.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heat flow guided heat dissipation distribution cabinet, including a cabinet body, which serves as the main structure of the distribution cabinet and is used to house other mechanisms and electrical components;
[0009] A flow guiding mechanism, wherein two flow guiding mechanisms are respectively installed on both sides of the inner wall of the top of the cabinet;
[0010] The heat dissipation mechanism has mounting openings on both sides of the outer wall near the sides, and the heat dissipation mechanism is installed inside the mounting openings.
[0011] The two drainage mechanisms are respectively installed on one side of the inner wall of the bottom of the cabinet near both ends; and,
[0012] The heat dissipation mechanism is installed on both sides of the top of the outer wall of the cabinet. The flow guiding mechanism, heat dissipation mechanism, flow diversion mechanism and heat dissipation mechanism are combined to form a heat flow guiding path.
[0013] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, the airflow guiding mechanism includes a first airflow guide plate and a second airflow guide plate. The first airflow guide plate and the second airflow guide plate are both installed on one side of the inner wall of the top of the cabinet. The first airflow guide plate is located directly above the second airflow guide plate. The first airflow guide plate is inclined downwards, and the second airflow guide plate is inclined upwards and does not intersect with the first airflow guide plate. The first airflow guide plate and the second airflow guide plate form an airflow movement structure with a large opening on one side and a small opening on the other side.
[0014] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, trapezoidal guide grooves are opened at the center line of the inner walls of the first guide plate and the second guide plate, which are close to each other, and multiple inclined grooves are opened on both sides of the surface of the first guide plate and the second guide plate near the guide grooves.
[0015] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, wherein: the outer walls of the first guide plate and the second guide plate are respectively opened with slots, and multiple first fans are installed inside the slots.
[0016] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, the cabinet body has a rectangular opening at one end near the guide plate, the heat dissipation mechanism is set inside the rectangular opening, and the heat dissipation mechanism includes two dustproof heat dissipation meshes, which are respectively snapped and installed on the inner wall of the rectangular opening near both ends.
[0017] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, a protective frame is fixedly installed on the outer wall of the cabinet near the outer side of the dustproof heat dissipation mesh.
[0018] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, the heat flow guiding mechanism includes a triangular seat, which is installed on one side of the inner wall of the bottom of the cabinet. The triangular seat is located below the dustproof heat dissipation mesh, and a plurality of second fans are installed on the surface of the triangular seat.
[0019] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, the cabinet has multiple trapezoidal mounting openings on both outer walls. The upper side of the mounting opening near the second fan is wider than the lower side, and the upper side of the mounting opening on the other outer wall of the cabinet is narrower than the lower side. An aluminum plate is fixedly installed inside each mounting opening, and the outer wall of the aluminum plate is flush with the outer wall of the cabinet.
[0020] As a preferred embodiment of the heat flow guiding heat dissipation distribution cabinet of this utility model, a plurality of heat dissipation fins are fixedly installed on the outer wall of the aluminum plate.

[0022] The beneficial effects of this heat flow guiding heat dissipation distribution cabinet are as follows: It adopts two inwardly recessed guide plates, one and the other, with one side having a large opening and the other side having a small opening. According to the principle of fluid mechanics, when hot air enters the channel formed by the guide plates from the side with the large opening, the flow rate of the hot air will increase as the channel gradually narrows. This variable cross-section channel design can effectively guide the heat flow and quickly and centrally deliver the hot air to the heat dissipation outlet of the distribution cabinet, avoiding the disorderly accumulation of hot air in the cabinet.
[0023] The bottom of the second guide plate is equipped with a first fan. After the air passes through the heat dissipation mechanism, it is blown by the second fan at the bottom and then guided by the heat dissipation mechanism on the other side. This causes the internal gas to move into the channel or into the top of the cabinet in a clockwise manner. Then, under the action of the first fan above the channel or the first guide plate, the hot air is discharged from the cabinet by the heat dissipation mechanism.
[0024] The aluminum plate and heat dissipation fins in the heat dissipation mechanism work together to dissipate heat. The aluminum plate has good thermal conductivity and can quickly absorb the heat generated by the electrical components inside the cabinet. The heat dissipation fins increase the heat dissipation area and accelerate the dissipation of heat into the surrounding air. Attached Figure Description

Detailed Implementation
[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0035] Example 1
[0036] Reference Figure 1 , Figure 2 and Figure 5 This is the first embodiment of the present utility model. This embodiment provides a heat flow guided heat dissipation distribution cabinet, which can guide the flow of gas and make the heat inside the cabinet quickly dissipate. It includes a cabinet 100, which serves as the main structure of the distribution cabinet and is used to house other mechanisms and electrical components.
[0037] Two flow guiding mechanisms 300 are respectively installed on both sides of the inner top wall of the cabinet 100;
[0038] The heat dissipation mechanism 200 has installation openings on the middle of both outer walls of the cabinet 100 near the sides, and the heat dissipation mechanism 200 is installed inside the installation openings.
[0039] Two flow diversion mechanisms 500 are respectively installed on one side of the bottom inner wall of the cabinet 100 near both ends; and,
[0040] The heat dissipation mechanism 400 is installed on both sides of the top of the outer wall of the cabinet 100. The heat dissipation mechanism 200, the heat diversion mechanism 500 and the heat dissipation mechanism 400 are combined to form a heat flow guiding path.
[0041] During use, the electrical components inside the cabinet 100 generate heat when working. The airflow guiding mechanism 300 is activated to guide the airflow clockwise into the heat dissipation mechanism 200. Some of the heat is directly discharged by the heat dissipation mechanism 200, and the airflow continues to move downward clockwise. Then, the airflow guiding mechanism 500 carries the airflow to the heat dissipation mechanism 200 on the other side of the cabinet 100. The heat dissipation mechanism 200 then delivers the airflow upward, allowing it to enter the channel inside the airflow guiding mechanism 300 or enter the top of the cabinet 100. Under the action of the airflow guiding mechanism 300, the gas is discharged from the heat exhaust mechanism 200 to the outside of the cabinet 100.
[0042] Example 2
[0043] Reference Figures 1 to 3 and Figure 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the flow guiding mechanism 300 includes a first flow guiding plate 301 and a second flow guiding plate 302. Both the first flow guiding plate 301 and the second flow guiding plate 302 are installed on one side of the inner wall of the top of the cabinet 100. The first flow guiding plate 301 is located directly above the second flow guiding plate 302. The first flow guiding plate 301 is inclined downward, and the second flow guiding plate 302 is inclined upward and does not intersect with the first flow guiding plate 301. The first flow guiding plate 301 and the second flow guiding plate 302 form an airflow movement structure with a large opening on one side and a small opening on the other side.
[0044] Two inward-facing guide vanes, 301 and 302, are used, with one side having a larger opening and the other side having a smaller opening. According to the principles of fluid mechanics, when hot air enters the channel formed by guide vanes 301 and 302 from the side with the larger opening, the flow rate of the hot air will increase as the channel gradually narrows. This variable cross-section channel design can effectively guide the heat flow and quickly and centrally deliver the hot air to the heat dissipation outlet of the distribution cabinet.
[0045] Specifically, trapezoidal guide grooves 305 are opened on the inner walls of guide plate 1 301 and guide plate 2 302 that are close to each other, and multiple inclined grooves 306 are opened on both sides of the surface of guide plate 1 301 and guide plate 2 302 near the guide grooves 305.
[0046] The guide channel 305 is designed with trapezoidal openings of varying sizes, which can accelerate the movement of airflow. The inclined channel 306 facilitates the entry of gas into the guide channel 305, thereby enhancing the guidance of airflow and allowing heat to be quickly discharged outside the cabinet 100.
[0047] Furthermore, both the first guide plate 301 and the second guide plate 302 have slots 303 on their outer walls that are far apart from each other, and multiple first fans 304 are installed inside the slots 303.
[0048] The first fan 304 is activated to accelerate the airflow inside the cabinet 100 and guide the heat flow.
[0049] The cabinet 100 has a rectangular opening near the end of the guide plate 301. The heat dissipation mechanism 400 is located inside the rectangular opening. The heat dissipation mechanism 400 includes two dustproof heat dissipation meshes 401, which are respectively snapped and installed on the inner wall of the rectangular opening near both ends.
[0050] Preferably, a protective frame 101 is fixedly installed on the outer wall of the cabinet 100 near the outer side of the dustproof heat dissipation mesh 401.
[0051] During use, the airflow inside the cabinet 100 flows clockwise under internal guidance, thus entering the channels in the first guide plate 301 and the second guide plate 302. After being guided by the channels, the heat is discharged outward by the dustproof heat dissipation mesh 401. The protective frame 101 provides protection, making it difficult for external dust to enter the interior of the cabinet 100.
[0052] Example 3
[0053] Reference Figures 1 to 5 This is the third embodiment of the present utility model. Unlike the previous embodiment, the flow diversion mechanism 500 includes a triangular seat 501. The triangular seat 501 is installed on one side of the bottom inner wall of the cabinet 100. The triangular seat 501 is located below the dustproof heat dissipation mesh 401. Multiple second fans 502 are installed on the surface of the triangular seat 501.
[0054] Specifically, multiple trapezoidal mounting openings are provided on both outer walls of the cabinet 100. The upper side of the mounting opening near the second fan 502 is wider than the lower side, while the upper side of the mounting opening on the other outer wall of the cabinet 100 is narrower than the lower side. An aluminum plate 201 is fixedly installed inside each mounting opening, and the outer wall of the aluminum plate 201 is flush with the outer wall of the cabinet 100.
[0055] Furthermore, multiple heat dissipation fins 202 are fixedly installed on the outer wall of the aluminum plate 201.
[0056] The aluminum plate 201 and the heat dissipation fins 202 work together to dissipate heat. The aluminum plate 201 has good thermal conductivity and can quickly absorb the heat generated by the electrical components inside the cabinet 100. The heat dissipation fins 202 increase the heat dissipation area and accelerate the dissipation of heat into the surrounding air.
[0057] Among them, a guide block 203 is installed on the inner wall of aluminum plate 201 at the position where it fits the wide side, and a guide block 204 is installed on the inner wall of aluminum plate 201 at the position where it fits the narrow side.
[0058] When in use, the inclined sides of guide block 1 203 and guide block 2 204 are designed to guide the airflow, thereby enabling the hot air to be transported quickly and in a concentrated manner, and under the guidance, the hot air can be easily discharged to the outside of the cabinet 100.
[0059] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.
[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
