[0032] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0033] With the continuous progress and development of technology, the replacement of electronic products is getting faster and faster, but the heat dissipation of electronic products has always been a problem. During the use of electronic products, heat will be continuously generated. Excessive internal heat will affect the normal operation of components. Therefore, a heat dissipation device is needed to quickly discharge the internal heat, so as to ensure the normal operation of electronic products. Generally speaking, since the internal components of electronic products are concentratedly installed at the bottom, the heat dissipation device is generally arranged at the top or the upper middle part to dissipate heat inside.

[0034] There are technical problems in the heat dissipation devices in the related art, such as poor heat dissipation effect.

[0035] Please refer to Figures 1-3 , this embodiment provides an efficient heat dissipation device 100, which can effectively improve the above-mentioned technical problems and can effectively ensure the heat dissipation effect of electronic products.

[0036] The efficient heat dissipation device 100 includes an installation box body 10, a fan 20, a heat dissipation member 30, and a movable grille plate 40. The fan 20 is arranged at the top of the installation box body 10, the heat dissipation member 30 is arranged at the bottom of the installation box body 10, the movable grille plate 40 movably covers the air outlet 302 of the heat dissipation member 30, and the movable grille plate 40 is used to adjust the heat dissipation area of the heat dissipation member 30.

[0037] In this embodiment, the efficient heat dissipation device 100 is mainly applied to electronic products with a top air outlet structure. Specifically, the installation box body 10 includes a top cover plate 11 and a plurality of columns 12. The plurality of columns 12 are sequentially arranged on the bottom surface of the top cover plate 11 along the circumferential direction, and the plurality of columns 12 are all arranged in the vertical direction. The fan 20 is installed on the top cover plate 11.

[0038] A condenser water receiving partition and a fin heat exchanger are also provided inside the installation box body 10. The heat dissipation member 30 passes through the condenser water receiving partition and communicates the upper and lower parts of the installation box body 10. After the fan 20 is started, the blades rotate at a high speed, thereby driving the air flow inside the installation box body 10 to rotate at a high speed, so as to form a negative pressure at the top of the installation box body 10, and draw the heat-carrying gas inside the installation box body 10 upward, thereby achieving the purpose of heat dissipation.

[0039] In this embodiment, the air outlet 302 of the heat dissipation member 30 is located above the condenser water receiving partition, and the height of the air outlet 302 should be 20 mm higher than the condenser water receiving partition.

[0040] In the prior art, since the internal heat-generating components are generally installed at the bottom of the installation box 10, such as compressors, copper tube refrigerants, etc. Therefore, the heat at the bottom of the installation box 10 is greater than that at the top. Since the fan 20 is installed at the top of the installation box 10, the heat dissipation effect at the bottom of the installation box 10 is poor. Generally, a small fan is provided at the bottom of the installation box 10 to dissipate heat from the bottom of the installation box 10, but the small fan is prone to damage during use, and at the same time, the heat dissipation effect for the bottom of the installation box 10 is not ideal. To solve this technical problem, when the high-efficiency heat dissipation device 100 provided in this embodiment is in use, after the fan 20 is started, the high-speed rotation of the fan 20 blades can drive the air flow inside the installation box 10 to flow at a high speed, thereby forming a negative pressure to suck the heat inside the installation box 10 upward, so as to extract the heat inside the installation box 10. At the same time, the air flow located at the bottom of the installation box 10 will also flow upward under the action of the negative pressure. At this time, the heat dissipation member 30 can simultaneously form a heat dissipation path at the bottom of the installation box 10, so as to ensure the heat dissipation effect at the bottom of the installation box 10. At the same time, a movable grille plate 40 is movably provided at the air outlet 302 of the heat dissipation member 30. By moving the movable grille plate 40, the heat dissipation area of the heat dissipation member 30 is adjusted, further improving the heat dissipation effect.

[0041] It should be noted that the position of the movable grille plate 40 at the air outlet 302 is adjusted according to the wind speed of the fan 20, so as to adjust the heat dissipation area of the heat dissipation member 30, making the high-efficiency heat dissipation device 100 more adaptable and more versatile.

[0042] In this embodiment, the heat dissipation member 30 includes an air inlet part 31 and an air outlet part 32 that are connected and communicate with each other. The air inlet 301 of the heat dissipation member 30 is provided at the air inlet part 31, and the air outlet 302 of the heat dissipation member 30 is provided at the air outlet part 32. Among them, both the air inlet part 31 and the air outlet part 32 are square frame structures. The air inlet part 31 is arranged vertically, the air inlet 301 is located at the bottom end of the air inlet part 31, and there is an included angle between the air outlet part 32 and the air inlet part 31.

[0043] Specifically, the included angle is 45°-60°. In this embodiment, the included angle is 50°. In other embodiments, the included angle can be 45°, 55° or 60°, which are not specifically limited here.

[0044] Specifically, a drive circuit board is connected to one side of the air inlet part 31, and the heat sink of the drive circuit board is located inside the air inlet part 31, so as to ensure that the drive circuit board can be cooled when the gas flows inside the air inlet part 31. The drive circuit board is connected to the electrical box, and the outside of the electrical box is covered with an electrical box cover plate.

[0045] In this embodiment, the air outlet 302 is located at one end of the air outlet part 32 away from the air inlet part 31, and the air outlet 302 is arranged downward. This prevents rainwater from entering the inside of the heat dissipation member 30, thereby affecting the normal operation of the components inside the installation box 10.

[0046] In order to prevent flying insects and the like from entering the installation box 10, an insect-proof net is provided at the air inlet 301 of the heat dissipation member 30 of the high-efficiency heat dissipation device 100 provided in this embodiment.

[0047] In addition, the high-efficiency heat dissipation device 100 further includes fasteners. The movable grille 40 and the air outlet 302 of the air outlet part 32 are connected by fasteners. Among them, the air outlet part 32 is provided with oblong holes, and the fasteners are movably arranged in the oblong holes for driving the movable grille 40 to move relative to the air outlet part 32.

[0048] Specifically, oblong holes are provided at both ends of the air outlet part 32 for enabling the movable grille 40 to perform reciprocating motion relative to the air outlet part 32. Among them, the air outlet 302 is also provided with a grille net. The oblong holes are arranged at both ends of the grille net, and the oblong holes are arranged along the length direction of the grille net, so that the movable grille 40 can perform reciprocating motion relative to the air outlet part 32.

[0049] In this embodiment, the fastener is a bolt.

[0050] A high-efficiency heat dissipation device 100 provided in this embodiment has at least the following advantages:

[0051] In the prior art, since the internal heat-generating components are generally installed at the bottom of the installation box 10, such as compressors, copper tube refrigerants, etc. Therefore, the heat at the bottom of the installation box 10 is greater than that at the top. Since the fan 20 is installed at the top of the installation box 10, the heat dissipation effect at the bottom of the installation box 10 is poor. Generally, a small fan is provided at the bottom of the installation box 10 to dissipate heat from the bottom of the installation box 10, but the small fan is prone to damage during use, and at the same time, the heat dissipation effect on the bottom of the installation box 10 is not ideal. To solve this technical problem, when the high-efficiency heat dissipation device 100 provided in this embodiment is in use, after the fan 20 is started, the high-speed rotation of the fan 20 blades can drive the air flow inside the installation box 10 to flow at a high speed, thereby forming a negative pressure to suck the heat inside the installation box 10 upward, thereby extracting the heat inside the installation box 10. At the same time, the air flow located at the bottom of the installation box 10 will also flow upward under the action of the negative pressure. At this time, the heat dissipation member 30 can simultaneously form a heat dissipation path at the bottom of the installation box 10, thereby ensuring the heat dissipation effect at the bottom of the installation box 10. At the same time, the air outlet 302 of the heat dissipation member 30 is movably provided with a movable grille 40, and the heat dissipation area of the heat dissipation member 30 is adjusted by moving the movable grille 40, further improving the heat dissipation effect.

[0052] In summary, the embodiment of the present utility model provides an efficient heat dissipation device 100. The efficient heat dissipation device 100 includes an installation box body 10, a fan 20, a heat dissipation member 30, and a movable grille plate 40. The fan 20 is arranged at the top of the installation box body 10, the heat dissipation member 30 is arranged at the bottom of the installation box body 10, the movable grille plate 40 movably covers the air outlet 302 of the heat dissipation member 30, and the movable grille plate 40 is used to adjust the heat dissipation area of the heat dissipation member 30. When in use, the fan 20 is installed at the top of the installation box body 10, and the heat dissipation member 30 is installed at the bottom of the installation box body 10. The installation box body 10 can provide space for the installation of components. When heat dissipation is required, the fan 20 is started. The high-speed rotation of the fan 20 can drive the air flow inside the installation box body 10 to flow at a high speed, thereby forming a negative pressure to suck the heat inside the installation box body 10 upward, so as to extract the heat inside the installation box body 10, thereby realizing heat dissipation. During the heat dissipation process, the heat dissipation member 30 can simultaneously form a heat dissipation path at the bottom of the installation box body 10, so as to ensure the heat dissipation effect at the bottom of the installation box body 10. At the same time, the air outlet 302 of the heat dissipation member 30 is movably provided with a movable grille plate 40.
