Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a photovoltaic power storage chassis. Background Technology

[0002] Optical storage power products have two or more inductor slots independently fixed at the bottom of the enclosure, and the heatsink for the MOSFET is also separately fixed at the bottom of the enclosure. Fixing the inductor slots at the bottom of the enclosure increases the overall height of the unit, and fixing the MOSFET heatsink at the bottom of the enclosure increases the overall size of the unit. The MOSFET requires a separate heatsink for heat dissipation, which increases the cost. The use of axial fans, which are placed outside the enclosure, results in excessive noise from the entire unit.

[0003] Therefore, it is necessary to provide a photovoltaic power supply chassis that reduces the overall height, is aesthetically pleasing, lightweight, and inexpensive, while meeting the requirements for heat dissipation and waterproofing. Utility Model Content

[0031] Please see Figures 1-4As shown, this utility model provides a photovoltaic power storage chassis, including a base 100 and a top cover 200. The base 100 includes a bottom plate 110 and a side plate 120. The side plate 120 is installed on the top surface of the bottom plate 110, and the top cover 200 is installed on the top surface of the side plate 120. The bottom plate 110, the side plate 120, and the top cover 200 together form a cavity. A PCB board 130 is provided on the bottom plate 110. The PCB board 130 is provided with an air inlet cover 140 arranged vertically and an air outlet cover 150 arranged horizontally. One end of the air inlet cover 140 is connected to the air outlet cover 150, and the other end is connected to the side plate 120. One end of the air outlet cover 150 is connected to the side plate 120. The side plate 120 is provided with an air inlet 121 corresponding to the position of the air inlet cover 140. An air outlet 122 is provided at the position corresponding to the air outlet cover 150. The air inlet cover 140 is sealed to the air outlet cover 150, the PCB board 130 and the side plate 120. The air outlet cover 150 is sealed to the PCB board 130 and the side plate 120. An air inlet channel is formed between the air inlet cover 140 and the PCB board 130. An air outlet channel is formed between the air outlet cover 150 and the PCB board 130. The air inlet channel and the air outlet channel are connected. An electrical component 131 and an electrical component 132 are provided on the PCB board 130. The electrical component 131 abuts against the outer wall of the air inlet cover 140 or the air outlet cover 150. The electrical component 132 is located in the air inlet channel. A fan 160 is provided in the air inlet channel or the air outlet channel.

[0032] Specifically, the base plate 110, the side plate 120, and the top cover 200 form a box, with an internal cavity for installing electrical components. The box is approximately rectangular, but can also be other shapes. Sealing rings or waterproof adhesive are used at the joints of each component to ensure the device's sealing and waterproof performance. In this embodiment, the photovoltaic power supply chassis has a waterproof rating of IP54 or IP65. The air inlet cover 140 and the air outlet cover 150 are sealed to the PCB board 130, effectively dividing the internal cavity of the chassis into two parts: the inner part of the air inlet cover 140 and the outer part is for heat dissipation, and the outer part is for component installation; the two parts are not connected. When the fan 160 operates, it drives airflow, directly dissipating heat from the electrical components 132 located in the heat dissipation section. As the airflow occurs, the heat from the air inlet cover 140 and the air outlet cover 150 is carried away, which also helps to dissipate heat from other components inside the cavity. For electrical component 131, which generates a relatively large amount of heat, placing it close to the air inlet cover 140 can improve heat dissipation. The air inlet cover 140 and the air outlet cover 150 are made of aluminum profiles or other materials with good thermal conductivity. The electrical component 132 located in the air inlet channel is itself waterproofed by applying some waterproof adhesive, and the PCB board surface is also waterproofed.

[0033] In one embodiment, the other end of the air outlet cover 150 is also connected to the side plate 120, and the number of air outlets 122 is two, such as... Figure 2 In the middle, there is a T-shaped heat dissipation structure. The air inlet cover 140 and the air outlet cover 150 are connected in the middle section, which is equivalent to bottom air intake and left and right air outlet.

[0034] As one implementation, the side plate 120 is provided with a waterproof connector 123 that communicates with the internal cavity, facilitating the connection of electrical components.

[0035] In one implementation, the air inlet cover 140, the air outlet cover 150, and the PCB board 130 are welded or screwed together, or they can be fixed with glue, as long as sealing is ensured. Thermally conductive adhesive is applied to the connection between the electrical component 131 and the air inlet cover 140 or the air outlet cover 150, and waterproof adhesive is applied to the connection between the air inlet cover 140 and the air outlet cover 150 and the PCB board 130, creating a waterproof structure and improving waterproofing and heat dissipation performance. It should be further noted that any other components used to achieve the above effects should fall within the inventive concept of this utility model and should be protected within the scope of this utility model.

[0036] In one implementation, the first electrical component 131 includes a MOSFET, and the second electrical component 132 includes an inductor and a transformer. The installation position of the electrical components is determined according to their performance and heat dissipation requirements.

[0037] As one implementation, the fan 160 is a centrifugal fan and is located at the connection point of the air inlet channel and the air outlet channel, which has good heat dissipation performance and low noise.

[0038] In one embodiment, the upper cover 200 and the side plate 120 are connected by a snap-fit ​​or screw connection. A waterproof rubber ring is provided between the upper cover 200 and the side plate 120. Filters are provided at both the air inlet 121 and the air outlet 122, and a waterproof rubber ring is provided at the connection between the filter and the side plate 120. It should be further noted that any other components used to achieve the above effects should fall within the inventive concept of this utility model and should be protected within the scope of this utility model.

[0039] Working Principle: The base 100 houses the air inlet cover 140 and the air outlet cover 150, with waterproof adhesive applied at the connection points to ensure the chassis's waterproof performance. Fans 160 are installed inside the air inlet cover 140 and the air outlet cover 150 to dissipate heat from the electrical components inside and on the outer walls of these covers. This reduces the overall height of the power supply, achieving a small, aesthetically pleasing, lightweight, and low-cost design. It provides airflow for the inductors and transformers while also cooling the MOSFETs, achieving multiple uses for a single component and maximizing cost savings. The fans, placed inside the chassis, significantly reduce overall noise and greatly improve the customer experience.

[0040] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
