Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a modular quick-installation heat dissipation electrical control box suitable for complex outdoor environments, and particularly to an innovative structural design with a quick-installation and disassembly module tray, heat dissipation components, and a linkage protective door. Background Technology

[0002] As an enclosed device integrating low-voltage switchgear and supporting control, measurement, signal, and protection components, the electrical control box continuously generates heat during operation due to the densely packed electrical control equipment inside. To prevent overheating and equipment failure, traditional solutions typically involve passive cooling through ventilation holes in the box. However, this design has significant drawbacks: A conflict between waterproofing and heat dissipation: open ventilation holes cannot prevent external moisture (such as rainwater and condensation), leading to increased short-circuit rates due to humid air intrusion. A high percentage of failures are caused by water entering the ventilation holes. Low energy efficiency: constantly open ventilation holes result in heat waste in low-temperature environments. Lack of modular expansion: existing quick-installation solutions with snap-on brackets only accommodate a single equipment size, increasing modification costs and inefficient installation and maintenance when expanding to new modules. Summary of the Invention

[0003] To overcome the technical shortcomings of existing electrical control boxes, such as inefficient installation and maintenance and high labor intensity for workers, this invention provides a modular, quick-installation, heat-dissipating electrical control box.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0029] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example

[0030] Reference Figures 1 to 5 This embodiment provides a modular, quick-installation, heat-dissipating electrical control box, comprising: a box body 1, with vertical support components 3 on its left and right inner side walls; a modular support plate 2, with ball bearing sliders 201 on both sides of its bottom, the ball bearing sliders 201 being slidably connected to the T-shaped guide rails 301 of the support components 3; an air inlet 4, located at the bottom front of the box body 1, including an outwardly inclined inverted V-shaped baffle 402 and an embedded dustproof mesh; an air outlet component 5, located at the top of the box body 1, including a stepped waterproof step 502 and a cantilevered rain shield 504; and a box door 9, hinged to the box body 1 via a four-bar linkage consisting of a long rocker arm 7 and a short rocker arm 8, with a slot 11 on the outer side of the box door 9, which engages with a lock 13 on a support 12 for locking. The lock 13 is rotatably connected to the support 12, and the lock 13 can be rotated to different positions to engage with the slot 11 for opening and closing.

[0031] Specifically, the cross-section of the T-shaped guide rail 301 is an inverted trapezoid, wider at the top and narrower at the bottom. The inner wall of the slide groove 302 is provided with a polytetrafluoroethylene (PTFE) wear-resistant layer. The diameter of the balls in the ball slider 201 is closely fitted to the width of the groove in the T-shaped guide rail 301. The T-shaped guide rail 301 is located on both sides inside the electrical box body 1. The ball slider 201 fits tightly with the T-shaped guide rail 301 to ensure smooth sliding without wobbling. A layer of PTFE wear-resistant material is adhered to the inner wall of the slide groove 302.

[0032] Specifically, the limiting pin 303 and the spring 304 are embedded in the front end of the slide groove 302. The limiting pin 303 is engaged with one side of the tray by the spring pressure, achieving automatic locking. Pressing the limiting pin 303 can overcome the elastic force of the spring 304 to unlock the tray.

[0033] Specifically, the inverted V-shaped baffles 402 are tilted at an angle of 30°-40° and arranged in a herringbone pattern.

[0034] Specifically, the ratio of the bottom area of ​​the rain shield 504 to the area of ​​the screen 501 is 1.3:1. The cantilevered rain shield 504 and the stepped waterproof steps 502 at the bottom ensure that rainwater is kept away from the heat dissipation channels.

[0035] Specifically, the module tray 2 has vent holes evenly distributed on its surface. These vent holes are spaced at regular intervals, with rounded edges to facilitate the upward escape of hot air.

[0036] Specifically, the length ratio of the long rocker arm 7 to the short rocker arm 8 in the four-bar linkage is 2:1 to 3:1. The bottom bracket 6 is square and fixedly connected to the lower side of the electrical box body 1, cooperating with the long rocker arm 7, the short rocker arm 8, and the box door 9 to form a double rocker arm mechanism. The hinge points use oil-impregnated bearings, and when the door 9 is opened, it forms a maintenance platform at a predetermined angle.

[0037] The working principle of the modular quick-installation heat-dissipating electrical control box in this embodiment is as follows:

[0038] During operation, the worker pushes the module tray 2 into the electrical box body 1 along the T-shaped guide rail 301 via the ball bearing slider 201. The limit pin 303, under the action of the spring 304, engages with the positioning hole of the tray to complete the fixation. When the temperature inside the box rises, external airflow is introduced through the inverted V-shaped baffle 402. Large dust particles slide off the baffle, and the filtered air enters the box to absorb heat. The hot airflow rises to the top rain cover 504 and is accelerated to be discharged. The waterproof step 502 prevents rainwater from flowing back in. During maintenance, pressing the limit pin 303 unlocks the module tray 2, and the guide wheel 303 slides out of the box along the slide groove 302. The box door 9 opens in conjunction with the long rocker arm 7 and the short rocker arm 8, and the anti-slip pad 9 ensures the safe operation of the pedal 8. Throughout the process, the vibration-resistant structure of the T-shaped guide rail 301 and the precise cooperation of the ball bearing slider 201 ensure the stability of the equipment, and the inverted V-shaped baffle 402 and the rain cover 504 work together to achieve a dynamic balance between heat dissipation and waterproofing.

[0039] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
