A mounting box for current conversion equipment

Abstract

This utility model discloses an installation box for a current conversion device, including a box body with a top cover installed at the upper end. The device has opening slots at both ends of the box body, with an outer frame installed inside the opening slots. A stainless steel protective mesh is installed inside the outer frame. This design achieves a dual function through the protective mesh. On the one hand, the protective mesh can promote heat dissipation through the airflow channel formed by the opening slots, ensuring that the heat inside the box is discharged in time. On the other hand, it can effectively block external debris and other impurities from entering the box body, protecting the core components from contamination. At the same time, the installation method of the outer frame and the opening slots is convenient and can be disassembled at any time. When the internal components are working continuously and generating a lot of heat, the outer frame can be removed, and heat dissipation can be carried out directly through the opening slots, thereby further expanding the heat dissipation channel and enhancing the overall heat dissipation effect. It takes into account both the protection needs in daily use and the heat dissipation efficiency under high load conditions.

Description

Technical Field

[0001] This utility model belongs to the technical field of mounting boxes for current conversion equipment, and specifically relates to a mounting box for current conversion equipment. Background Technology

[0002] The mounting box for current conversion equipment, also known as the equipment enclosure, is an outer shell structure that houses and protects the core components of current conversion. Inside, there is a converter board that converts DC to AC, a voltage conversion board that converts low voltage to high voltage, and a fan for auxiliary heat dissipation. The enclosure is equipped with a front cover to seal and protect the internal components, and it has DC input terminals and AC output terminals. Overall, it provides an integrated installation and protection space for the current conversion process.

[0003] When the mounting box is in use, the heat dissipation holes are distributed at the front and rear ends of the box, while there are no heat dissipation holes at the left and right ends. Since the box has a certain length, the core heat-generating components such as the power conversion board and voltage conversion board inside the box continuously generate heat during operation. This heat needs to be dissipated through air convection. If there are only heat dissipation holes at the front and rear, the air can only flow along a straight path from the front to the rear. The components near the left and right ends will be in the blind spots that the airflow cannot reach. The heat cannot be effectively carried away by the flowing air and gradually accumulates in the space on the left and right sides, forming local high temperature areas. Especially when the equipment is in a high temperature environment or under high load, the lack of heat dissipation holes on the left and right sides will exacerbate the problem of heat not being able to dissipate in time. Summary of the Invention

[0004] The purpose of this utility model is to provide a mounting box for current conversion equipment, in order to solve the problem mentioned in the background art where the heat dissipation holes are distributed at the front and rear ends of the box, but there are no heat dissipation holes at the left and right ends. Since the box has a certain length, the core heat-generating components such as the current conversion plate and voltage conversion plate inside the box continuously generate heat during operation. This heat needs to be discharged through air convection. If there are only heat dissipation holes at the front and rear, the air can only flow along a straight path from the front to the rear. The components near the left and right ends will be in the left and right blind areas that are difficult for the airflow to reach. The heat cannot be effectively carried away by the flowing air and gradually accumulates in the space on the left and right sides, forming local high temperature areas. Especially when the equipment is in a high temperature environment or under high load, the lack of heat dissipation holes on the left and right sides will exacerbate the problem of heat not being able to be discharged in time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation box for a current conversion device, comprising a box body, an upper cover installed at the upper end of the box body, a front cover installed at the front end of the box body, opening slots provided at the left and right ends of the box body, slots provided on the left and right sides of the inner wall of the opening slots, an outer frame installed on the inner side of the opening slots, a stainless steel protective mesh provided on the inner side of the outer frame, protrusions provided at the left and right ends of the outer frame, rotatable handles provided at the four corners of the front end of the outer frame, a connecting rod fixed at the rear end of the handle, and the connecting rod passing through the outer frame and fixed to a rotating plate at the other end.

[0006] Preferably, the housing, top cover, and front cover are installed together using stainless steel bolts.

[0007] Preferably, the front end of the front cover is provided with a DC input terminal at the left side position and an AC output terminal at the right side position.

[0008] Preferably, the front cover has multiple heat dissipation holes at its front end to dissipate heat generated by the internal components of the enclosure.

[0009] Preferably, a fan, a voltage conversion board, and a converter board are installed inside the housing.

[0010] Preferably, the outer frame is inserted into the inner position of the opening slot, while the protrusion is engaged with the inner position of the slot.

[0011] Preferably, the handle and the connecting rod rotate around a central axis, and the handle drives the rotating plate to rotate through the connecting rod.

[0012] Preferably, the stainless steel protective mesh is located on the inner side of the outer frame, and multiple mesh holes are distributed inside the stainless steel protective mesh for ventilation and heat dissipation.

[0013] Compared with the prior art, the present invention provides a mounting box for current conversion equipment, which has the following advantages: 1. This device has openings at both ends of the housing, with an outer frame installed inside the openings. The inner side of the outer frame is fitted with a stainless steel protective mesh. This design achieves a dual function through the protective mesh. On the one hand, the protective mesh can promote heat dissipation through the airflow channels formed by the openings, ensuring that heat inside the housing is discharged in a timely manner. On the other hand, it can effectively block external debris and other impurities from entering the housing, protecting the core components from contamination. At the same time, the installation of the outer frame and the openings is convenient and can be disassembled at any time. When the internal components are working continuously and generating a lot of heat, the outer frame can be removed, and heat can be dissipated directly through the openings, thereby further expanding the heat dissipation channel and enhancing the overall heat dissipation effect. This design takes into account both the protection needs in daily use and the heat dissipation efficiency under high load conditions.

[0014] 2. When installing the outer frame and the opening slot, insert the outer frame into the inner position of the opening slot, and at the same time, engage the protrusion with the inner position of the slot so that the outer frame does not enter the inner position of the box. Turn the handle to make the rotating plate fit against the inner wall of the box, and the installation of the outer frame and the opening slot is completed. This convenient installation method can increase the flexibility of use. Attached Figure Description

[0023] External DC power enters the enclosure through the DC input terminal 3 of the mounting box. It first flows through the converter plate to complete the DC-to-AC conversion, and then enters the voltage conversion plate to realize the low-voltage-to-high-voltage conversion. During the process, the fan runs continuously to dissipate heat from the converter plate, voltage conversion plate and other heat-generating components to ensure their stable operation. The front cover 5 is closed on the enclosure 1 to provide sealed protection for all internal components and avoid interference from the external environment. Finally, the converted high-voltage AC power is output through the AC output terminal 4. The entire process is completed in an orderly manner within the integrated space formed by the enclosure 1 and the internal fixed structure.

[0024] like Figure 2 and Figure 3As shown, the housing 1, top cover 2, and front cover 5 are installed together by stainless steel bolts 15. The front end of the front cover 5 has a DC input terminal 3 located on the left side and an AC output terminal 4 located on the right side. Multiple heat dissipation holes 6 are distributed at the front end of the front cover 5 to dissipate the heat generated by the internal components of the housing 1. A fan, voltage conversion board, and inverter board are installed inside the housing 1. The outer frame 10 is inserted into the opening slot 9, and the protrusion 12 is engaged with the slot 11. The handle 7 and the connecting rod 14 rotate around a central axis. When the handle 7 rotates, it drives the rotating plate 13 to rotate. The stainless steel protective mesh 8 is located inside the outer frame 10. Multiple mesh holes are distributed inside the stainless steel protective mesh 8 for ventilation and heat dissipation.

[0025] Insert the outer frame 10 into the inner position of the opening slot 9, and at the same time, snap the protrusion 12 into the inner position of the slot 11 so that the outer frame 10 will not enter the inner position of the box 1. Turn the handle 7 so that the rotating plate 13 fits against the inner wall of the box 1, and the installation of the outer frame 10 and the opening slot 9 can be completed.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
