Description

Technical Field

[0001] This utility model belongs to the field of power station box technology, and specifically relates to a heat dissipation structure for a power station box. Background Technology

[0002] Photovoltaic transformer boxes have strong airtightness, and in order to save materials and reduce space, the internal components of some transformer boxes are designed to be relatively compact. Some transformer boxes on the market use natural air cooling for heat dissipation. However, natural air cooling can easily cause the equipment inside the transformer box to be in a long-term high-temperature state. During long-term high-temperature operation, the equipment inside the transformer box may experience high-temperature alarms or even tripping, causing the transformer box to shut down and affecting power generation.

[0003] Currently, most of the natural air-cooled structures of box-type transformers on the market are grid structures that only have ventilation functions. Moreover, the grid plates of such grid structures are relatively fixed and inclined relative to the horizontal plane, which can easily affect the air intake and result in low heat dissipation efficiency of the power station box. Utility Model Content

[0004] In view of the above shortcomings, the technical problem to be solved by this utility model is to provide a heat dissipation structure for a power station box to improve the heat dissipation efficiency of the power station box.

[0005] A heat dissipation structure for a power station box includes a ventilation grille, a liquid cooling assembly, and a swing drive assembly. The ventilation grille includes a grille frame and multiple unit grille plates, each of which is installed within the grille frame and can swing relative to the grille frame. The liquid cooling assembly includes liquid cooling pipes and multiple parallel liquid cooling fins, which are connected to the unit grille plates. The liquid cooling pipes are connected to the liquid cooling fins and provide coolant to the liquid cooling fins. The swing drive assembly includes a drive shaft connected to the unit grille plates via the liquid cooling assembly. The unit grille plates are arranged along a first direction, and the liquid cooling fins are arranged along a second direction perpendicular to the first direction. The drive shaft can move relative to the grille frame along the second direction to drive the unit grille plates to swing.

[0006] Furthermore, the ventilation grille also includes a connecting shaft, which is installed inside the unit grille plate; the liquid cooling fins are connected to the unit grille plate via the connecting shaft.

[0007] Furthermore, a waist-shaped groove is formed within the unit grid plate, and a connecting shaft is installed within the waist-shaped groove so that the connecting shaft can move relative to the unit grid plate along a third direction; wherein, the first direction, the second direction, and the third direction are perpendicular to each other.

[0008] Furthermore, a mounting groove is formed on the unit grid plate, and the connecting shaft extends at least partially into the mounting groove; the liquid cooling plate extends at least partially into the mounting groove so that the liquid cooling plate is connected to the connecting shaft.

[0009] Furthermore, limit nuts are installed at both ends of the connecting shaft.

[0010] Furthermore, the liquid cooling pipe includes a recovery pipe, a connecting pipe, and a flexible pipe. The flexible pipe is connected to the liquid cooling plate through the connecting pipe and has a degree of freedom in deformation. A liquid cooling channel is formed inside the liquid cooling plate, and the connecting pipe and the recovery pipe are respectively connected to the liquid cooling channel.

[0011] Furthermore, the liquid cooling plate includes a finned portion and a tube portion, the finned portion being connected to the tube portion and the finned portion being connected to the unit grid plate, and the liquid cooling channel being formed inside the tube portion.

[0012] Furthermore, the oscillating drive assembly includes an eccentric wheel that can rotate relative to the liquid cooling assembly. The drive shaft is mounted on the eccentric wheel, and the rotation of the eccentric wheel drives the drive shaft to move in the second direction.

[0013] Furthermore, the swing drive assembly also includes a connecting seat, in which a connecting groove extending in a first direction is formed; the drive shaft is connected to the connecting groove.

[0014] Furthermore, the oscillation drive assembly is located above the liquid cooling assembly.

[0015] By incorporating liquid cooling components, the temperature of the airflow passing through the heat dissipation structure can be reduced, thereby improving the heat dissipation efficiency of the power station box. Furthermore, by incorporating swing drive components, the tilt angle of the unit grid plate relative to the horizontal plane can be adjusted, thereby increasing the opening area of ​​the heat dissipation structure on the projection surface along the airflow direction, increasing the airflow rate entering the power station box through the heat dissipation structure, and further improving the heat dissipation efficiency of the power station box.

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, as one implementation, this application provides a heat dissipation structure for a power station box. The heat dissipation structure is installed on the side wall of the power station box, and external air flows into the power station box through the heat dissipation structure to facilitate the replacement of air inside the power station box, thereby reducing the temperature inside the power station box and preventing the equipment inside the power station box from operating at high temperatures for a long time.

[0026] like Figure 1 As shown, the power station box includes a power station box body 4, a movable door 5, and a cooling fan 6. The movable door 5 is installed on the power station box body 4, and the movable door 5 can swing relative to the power station box body 4, thereby opening or closing the power station box body 4.

[0027] The cooling fan 6 is installed on the movable door 5, and the air inside the power station box body 1 is discharged to the outside of the power station box body 1 by the cooling fan 6.

[0028] Furthermore, the heat dissipation structure is installed on the side wall of the main body 4 of the power station box, and air flows into the main body 4 of the power station box through the heat dissipation structure.

[0029] To more clearly describe the technical solution of this application, the following are defined: Figure 1 The directions shown are up, down, left, right, front, and back. The first direction refers to... Figure 1 The left and right directions in the middle, the second direction refers to Figure 1 The vertical direction in the middle, the third direction refers to Figure 1 The front and back directions in the middle.

[0030] like Figures 3 to 7As shown, in one implementation, the heat dissipation structure includes a ventilation grille 1, a liquid cooling component 2, and a swing drive component 3. The ventilation grille 1 is fixed on the side wall of the power station box body 4. The liquid cooling component 2 is installed on the ventilation grille 1. The swing drive component 3 is installed on the side wall of the power station box body 4 and connected to the liquid cooling component 2. The swing drive component 3 drives the liquid cooling component 2 to move, thereby driving the ventilation grille 1 to swing, thereby changing the opening area of ​​the heat dissipation structure on the airflow projection surface, so as to increase the airflow entering the power station box through the heat dissipation structure, thereby improving the heat dissipation efficiency of the power station box.

[0031] Furthermore, coolant can flow through the liquid cooling component 2 to change the temperature of the liquid cooling component 2, thereby reducing the temperature of the air flowing through the liquid cooling component 2 and further improving the heat dissipation efficiency of the power station box.

[0032] The ventilation grille 1 includes a grille frame 1-1 and multiple unit grille plates 1-2. The unit grille plates 1-2 are arranged along a first direction. The multiple unit grille plates 1-2 are respectively installed in the grille frame 1-1, and the unit grille plates 1-2 can swing relative to the grille frame 1-1.

[0033] The swing drive component 3 drives the liquid cooling component 2 to move, thereby causing the unit grid plate 1-2 to swing, thus changing the opening area of ​​the heat dissipation structure on the projection surface along the airflow direction, so as to increase the airflow into the power station box through the heat dissipation structure, thereby improving the heat dissipation efficiency of the power station box.

[0034] The liquid cooling assembly 2 includes a liquid cooling pipe 2-1 and a plurality of liquid cooling plates 2-2 arranged in parallel with each other. The liquid cooling plates 2-2 are arranged along a second direction, which is perpendicular to the first direction. The liquid cooling plates 2-2 are connected to a plurality of unit grid plates 1-2. The liquid cooling pipe 2-1 is connected to the liquid cooling plates 2-2. The liquid cooling pipe 2-1 provides coolant to the liquid cooling plates 2-2, thereby reducing the amount of air flowing through the liquid cooling plates 2-2, so as to improve the heat dissipation efficiency of the power station box.

[0035] The swing drive assembly 3 includes a drive shaft 3-1, which can move relative to the grid frame 1-1 in a second direction. The drive shaft 3-1 is connected to the unit grid plate 1-2 through the liquid cooling plate 2-2 of the liquid cooling assembly 2, thereby driving the liquid cooling plate 2-2 to move up and down through the drive shaft 3-1, and then driving the unit grid plate 1-2 to swing through the liquid cooling plate 2-2.

[0036] It should be noted that when air flows through the liquid cooling plate 2-2, the surface temperature of the liquid cooling plate 2-2 is lower than the temperature of the air, which allows the liquid cooling plate 2-2 to exchange heat with the air, thereby appropriately reducing the temperature of the air flowing through the liquid cooling plate 2-2, and thus reducing the temperature of the air flowing into the power station box 1.

[0037] As one implementation, the ventilation grille 1 also includes a connecting shaft 1-5, which is installed inside the unit grille plate 1-2. The liquid cooling plate 2-2 is connected to the unit grille plate 1-2 through the connecting shaft 1-5 so that the unit grille plate 1-2 and the connecting shaft 1-5 can rotate relative to each other during the up-and-down movement of the liquid cooling plate 2-2.

[0038] As one implementation, a waist-shaped groove 1-3 is formed in the unit grid plate 1-2. The waist-shaped groove 1-3 extends along a third direction, that is, the waist-shaped groove 1-3 extends along the swing radius direction of the unit grid plate 1-2. The connecting shaft 1-5 is installed in the waist-shaped groove 1-3, so that the connecting shaft 1-5 can move relative to the unit grid plate 1-2 along a third direction, preventing interference during the swing of the unit grid plate driven by the liquid cooling plate 2-2.

[0039] It should be noted that a shaft hole is formed on the liquid cooling plate 2-2, and the connecting shaft 1-5 is inserted into the shaft hole. The connecting shaft 1-5 can rotate relative to the liquid cooling plate 2-2, which improves the smoothness of the liquid cooling plate 2-2 driving the unit grid plate to swing.

[0040] During the process of the swing drive assembly 3 driving the liquid cooling plate 2-2 to move up and down, the liquid cooling plate 2-2 drives the connecting shaft 1-5 to move up and down along the second direction. Since the connecting shaft 1-5 is inserted into the waist-shaped groove 1-3, the connecting shaft 1-5 drives the unit grid plate 1-2 to swing.

[0041] As one implementation, to facilitate the connection between the liquid cooling plate 2-2 and the unit grid plate 1-2, a mounting groove 1-4 is formed on the unit grid plate 1-2. The mounting groove 1-4 is at least partially connected to the waist-shaped groove 1-3 so that the connecting shaft 1-5 can at least partially extend into the mounting groove 1-4, and the liquid cooling plate 2-2 can at least partially extend into the mounting groove 1-4 so that the liquid cooling plate 2-2 is connected to the connecting shaft 1-5.

[0042] like Figure 5 As shown, in one implementation, limit nuts 1-6 are installed at both ends of the connecting shaft 1-5. The limit nuts 1-6 limit the connecting shaft 1-5, thereby facilitating the disassembly and assembly of the connecting shaft 1-5, and thus facilitating the assembly of the liquid cooling plate 2-2 and the unit grid plate 1-2.

[0043] like Figure 1 As shown, in one implementation, the power station box also includes an oil tank 7, which is fixed on the outer side wall of the power station box body 4 and is used to store coolant.

[0044] It should be noted that the oil tank 7 is equipped with a device for cooling the coolant, such as a semiconductor cooling chip, so as to ensure that the temperature delivered to the liquid cooling plate 2-2 is lower than the air temperature outside the power station box, thereby facilitating the appropriate reduction of the air temperature entering the power station box through the liquid cooling plate 2-2.

[0045] like Figure 3 As shown, in one implementation, the liquid cooling pipe 2-1 includes a recovery pipe 2-3, a connecting pipe 2-4, and a flexible pipe 2-5. A liquid cooling channel 2-6 is formed inside the liquid cooling plate 2-2. The connecting pipe 2-4 and the recovery pipe 2-3 are respectively connected to the liquid cooling channel 2-6. The flexible pipe 2-5 is connected to the liquid cooling plate 2-2 through the connecting pipe 2-4. The coolant is supplied from the oil tank 7 through the flexible pipe 2-5 and the connecting pipe 2-4 into the liquid cooling plate 2-2, and then flows back from the liquid cooling plate 2-2 to the oil tank 7 through the recovery pipe 2-3.

[0046] The flexible tube 2-5 has a degree of freedom of deformation, so as to facilitate connection with the oil tank 7.

[0047] It should be noted that a power pump is installed in the oil tank 7, and the coolant is delivered to the flexible tube 2-5 through the power pump so that the coolant can circulate between the oil tank 7 and the liquid cooling plate 2-2.

[0048] like Figure 6 As shown, in one implementation, the liquid cooling plate 2-2 includes a finned portion 2-7 and a tube portion 2-8. The finned portion 2-7 is connected to the tube portion 2-8 and is also connected to the unit grid plate 1-2. The finned portion 2-7 increases the contact area between the liquid cooling plate 2-2 and the air, thereby reducing the temperature of the air flowing through the liquid cooling plate 2-2.

[0049] Specifically, the liquid cooling channel 2-6 is formed inside the tube section 2-8, and the connecting tube 2-4 and the recovery tube 2-3 are respectively connected to the liquid cooling channel 2-6.

[0050] like Figure 7 As shown, in one implementation, the swing drive assembly 3 includes a motor 3-2 and an eccentric wheel 3-3. The motor 3-2 is fixed inside the main body 4 of the power station box, and the eccentric wheel 3-2 is mounted on the motor shaft of the motor 3-2. The motor 3-2 drives the eccentric wheel 3-2, thereby enabling the eccentric wheel 3-3 to rotate relative to the liquid cooling assembly 2. The drive shaft 3-1 is eccentrically mounted on the eccentric wheel 3-3. When the eccentric wheel 3-3 rotates, it drives the drive shaft 3-1 to move in the first direction and the second direction.

[0051] As one implementation, the swing drive assembly 3 also includes a connecting seat 3-4, in which a connecting groove 3-5 extending in a first direction is formed; the drive shaft 3-1 is connected to the connecting groove 3-5. During the movement of the drive shaft 3-1, the drive shaft 3-1 can move in the first direction relative to the connecting shaft 3-5, so that the connecting shaft 3-5 only drives the liquid cooling assembly 2 to move in the second direction, thereby realizing the swing of the unit grid plate 1-2.

[0052] As one implementation method, the swing drive component 3 is located above the liquid cooling component 2 to improve the movement stability of the liquid cooling component 2.

[0053] It should be noted that the length of the connecting shaft 3-5 along the first direction should be greater than the amount of movement of the drive shaft 3-1 along the first direction, so as to ensure that the drive shaft 3-1 only drives the connecting seat 3-4 to move up and down.

[0054] The working principle of this heat dissipation structure is as follows:

[0055] The eccentric wheel 3-3 is driven to rotate by the motor 3-2, which in turn drives the drive shaft 3-1 to move. The movement of the drive shaft 3-1 along the first direction is filtered by the connecting groove 3-5, so that the drive shaft 3-1 drives the liquid cooling component 2 to move up and down, which in turn drives the unit grid plate 1-2 to swing, changing the opening area of ​​the heat dissipation structure on the projection surface along the airflow direction. This increases the airflow into the power station box through the heat dissipation structure as needed, thereby improving the heat dissipation efficiency of the power station box.

[0056] Furthermore, as air flows through the liquid cooling component 2, it exchanges heat with the air through the liquid cooling component, appropriately reducing the air temperature entering the power box, thereby further improving the heat dissipation efficiency of the power box.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
