Description

Technical Field

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

[0002] The power supply box is the control center that directs the rational distribution of electrical energy among various components in the power supply line. It is a control link that reliably receives power from the upstream source and correctly feeds out the load power, and it is also key to obtaining user satisfaction with the power supply quality. In order to prevent the power supply box from exploding or operating in a high-temperature environment for a long time, efficient heat dissipation is required for the various components inside the power supply box (such as the power supply motherboard). In the existing patent, Chinese patent document with application number 201220017407.1 discloses a computer power supply box. The power supply box cover includes a horizontal cover plate, an inclined cover plate disposed on one side wall of the horizontal cover plate, and a rear cover plate disposed on one side wall of the inclined cover plate and perpendicular to the bottom plate of the lower cover. The angle between one end of the inclined cover plate and the horizontal cover plate is in the range of 0 degrees to 180 degrees, and the angle between the other end of the inclined cover plate and the rear cover plate is in the range of 0 degrees to 180 degrees. The inclined cover plate is provided with a plurality of fan cooling holes that cooperate with electric fans. Although the electric fan in the patent document is also installed at an angle, it requires an additional tilting plate on the top cover, making the structure complex, not compact, and large in size. Furthermore, the tilt angle of the electric fan is not adjustable. Therefore, the defects are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a power supply box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A power supply box includes a box body and a fan. The box body includes a top plate, a bottom plate, a first side plate, a second side plate, an end plate, and a heat dissipation mesh plate. The two ends of the top plate are connected to the top of the end plate and the top of the heat dissipation mesh plate, respectively. The two ends of the bottom plate are connected to the bottom of the end plate and the bottom of the heat dissipation mesh plate, respectively. The two sides of the first side plate are connected to one side of the top plate and one side of the bottom plate, respectively. The two sides of the second side plate are connected to the other side of the top plate and the other side of the bottom plate, respectively. The two ends of the first side plate are connected to one side of the end plate and one side of the heat dissipation mesh plate, respectively. The two ends of the second side plate are connected to the other side of the end plate and the other side of the heat dissipation mesh plate, respectively. The end of the fan near the heat dissipation mesh plate is installed on the inner wall of the top plate, and the end of the fan away from the heat dissipation mesh plate is installed on the inner wall of the top plate via at least one pad. The fan and the bottom plate are arranged at an angle, and the air outlet end of the fan is correspondingly arranged with the bottom plate.

[0006] Furthermore, the top plate has an air inlet, which is set to correspond to the air inlet end of the blower.

[0007] Furthermore, a dustproof screen is installed inside the air inlet.

[0008] Furthermore, the top plate is detachably connected with locking fasteners for securing the top plate, pad, and blower together or / and for securing the top plate and blower together.

[0009] Furthermore, the first side panel, top panel, and second side panel are a U-shaped integrated structure.

[0010] Furthermore, the heat dissipation mesh, base plate, and end plate are a U-shaped integrated structure.

[0011] Furthermore, the end plate has wire holes.

[0012] Furthermore, the heat dissipation mesh is equipped with wiring ports and / or on / off switches.

[0013] The beneficial effects of this utility model are as follows: In practical applications, the power supply motherboard is installed on the inner wall of the base plate and located below the blower. Since one end of the blower is directly installed on the inner wall of the top plate, and the other end of the blower is separated from the inner wall of the top plate by a spacer, the blower is tilted. The airflow from the tilted blower blows at an angle / tilt towards the inner wall of the base plate and / or the power supply motherboard, causing the airflow direction to change along the base plate and / or the power supply motherboard, carrying away the heat inside the enclosure and blowing it towards the heat dissipation mesh plate to expel the hot air into the external environment, thus improving the efficiency and effect of heat dissipation. Compared to the traditional method where the blower is parallel to the base plate, the airflow from the blower impacts the base plate vertically, and some airflow bounces back to the blower, causing the two airflows to collide, resulting in unstable / turbulent airflow inside the power supply enclosure and thus poor heat dissipation. This utility model has a compact structure and small size, and the tilted blower greatly improves the heat dissipation effect and efficiency. The tilt angle of the blower is adjustable.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 5As shown, this utility model provides a power supply box, which includes a box body 1 and a fan 2. The box body 1 includes a top plate 3, a bottom plate 4, a first side plate 5, a second side plate 6, an end plate 7, and a heat dissipation mesh plate 8. The two ends of the top plate 3 are respectively connected to the top of the end plate 7 and the top of the heat dissipation mesh plate 8. The two ends of the bottom plate 4 are respectively connected to the bottom of the end plate 7 and the bottom of the heat dissipation mesh plate 8. The two sides of the first side plate 5 are respectively connected to one side of the top plate 3 and one side of the bottom plate 4. The two sides of the second side plate 6 are respectively connected to the other side of the top plate 3. One side plate 5 is connected to the other side of the base plate 4. The two ends of the first side plate 5 are respectively connected to one side of the end plate 7 and one side of the heat dissipation mesh plate 8. The two ends of the second side plate 6 are respectively connected to the other side of the end plate 7 and the other side of the heat dissipation mesh plate 8. The end of the blower fan 2 close to the heat dissipation mesh plate 8 is installed on the inner wall of the top plate 3. The end of the blower fan 2 away from the heat dissipation mesh plate 8 is installed on the inner wall of the top plate 3 via at least one pad 9. The blower fan 2 is set at an angle to the base plate 4. The air outlet end of the blower fan 2 is set corresponding to the base plate 4. In practical applications, the power supply motherboard is installed on the inner wall of the base plate 4 and located below the blower fan 2. Since one end of the blower fan 2 is directly installed on the inner wall of the top plate 3, and the other end of the blower fan 2 is separated from the inner wall of the top plate 3 by a spacer block 9, the blower fan 2 is tilted inside the case 1. The airflow from the tilted blower fan 2 will blow towards the inner wall of the base plate 4 and / or the power supply motherboard at an angle / tilt, causing the airflow direction to change along the base plate 4 and / or the power supply motherboard, and carrying away the heat in the case 1 and blowing it towards the heat dissipation mesh plate 8 to blow the hot airflow out of the external environment, thus improving the efficiency and effect of heat dissipation. Compared with the traditional method where the blower fan 2 is parallel to the base plate 4, the airflow from the blower fan 2 impacts the base plate 4 vertically, and some airflow will bounce back to the blower fan 2, causing the two airflows to collide, thus making the airflow in the power supply case unstable / turbulent, resulting in poor heat dissipation. Furthermore, depending on the required angle between the fan 2 and the base plate 4, the tilt angle of the fan 2 can be changed by increasing or decreasing the number of pads 9 and / or altering the thickness of the pads 9, which helps improve the stability and flow rate of the heat dissipation airflow within the housing 1. This invention features a compact structure and small size, and the tilted design of the fan 2 significantly enhances the heat dissipation effect and efficiency. The tilt angle of the fan 2 is adjustable. This power supply box can be widely used in electronic products such as computer cases, headphones, cameras, and speakers.

[0023] In this embodiment, the top plate 3 is provided with an air inlet 10, which is correspondingly arranged with the air inlet end of the blower 2. In practical applications, when the blower 2 is working, outside air enters the air inlet end of the blower 2 through the air inlet 10.

[0024] In this embodiment, a dustproof net 11 is installed inside the air inlet 10. The dustproof net 11 not only serves to prevent dust but also provides protection.

[0025] In this embodiment, the top plate 3 is detachably connected to several locking fasteners, which are used to secure the top plate 3, the pad 9, and the blower 2 together, or / and to secure the top plate 3 and the blower 2 together. Specifically, bolts can be used as the locking fasteners. This structural design is simple, low-cost, facilitates the assembly and disassembly of the top plate 3 and the blower 2, and provides a secure connection.

[0026] In this embodiment, the first side plate 5, the top plate 3, and the second side plate 6 are U-shaped integrated structures, which facilitates manufacturing, reduces the splicing gaps of the box 1, has good structural integrity, high strength and hardness, and an aesthetically pleasing appearance.

[0027] In this embodiment, the heat dissipation mesh plate 8, the bottom plate 4, and the end plate 7 are U-shaped integrated structures, which facilitates manufacturing, reduces the splicing gaps of the box 1, has good structural integrity, high strength and hardness, and an aesthetically pleasing appearance.

[0028] In this embodiment, the end plate 7 has a wire-passing hole 12. The wire-passing hole 12 is used to allow the connecting wire to enter the housing 1 or extend out of the housing 1.

[0029] In this embodiment, the heat dissipation mesh plate 8 is equipped with a wiring port 13 and / or an on / off switch 14, and the power supply main board is electrically connected to the wiring port 13 and the on / off switch 14 via a connecting wire.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
