Description

Technical Field

[0001] This utility model relates to the field of dustproof bracket technology, and in particular to a power supply exhaust and heat dissipation device. Background Technology

[0002] Power supply exhaust cooling devices primarily use the operation of fans to generate airflow, carrying away heat from inside the power supply and expelling it to the external environment. When the power supply is running, its internal electronic components generate heat. If this heat is not dissipated in time, it will cause the power supply temperature to rise, thereby affecting the stability and lifespan of the power supply. Therefore, exhaust cooling devices use the operation of fans to draw in cool external air into the power supply, and after heat exchange, expel the hot air to the external environment, thereby achieving the purpose of heat dissipation and cooling.

[0003] In existing technologies, dust tends to accumulate in key parts of power supply exhaust and heat dissipation devices, such as fan blades and inside the power supply. The dust layer hinders heat transfer, leading to a decrease in heat dissipation efficiency. As dust continues to accumulate, the heat dissipation effect will become worse and worse, and may even cause the power supply to overheat, resulting in malfunctions or damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing power supply exhaust and heat dissipation devices, where dust easily accumulates in key parts such as the fan blades and inside the power supply, hindering heat transfer. Therefore, this invention proposes a power supply exhaust and heat dissipation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power supply exhaust and heat dissipation device, comprising a power supply housing, a dustproof device provided on one side of the power supply housing, the dustproof device comprising a square pipe, the outside of the square pipe being fixedly connected to the power supply housing, a cooling fan being fixedly connected to the inside of the square pipe, fixing blocks being fixedly connected to both sides of the square pipe, an internally threaded pipe being fixedly connected to one side of the fixing block, a bolt being threaded inside the internally threaded pipe, a connecting plate being slidably connected to the arc surface of the bolt, and a dustproof net being fixedly connected to the side of the two connecting plates that are close to each other.

[0006] The above components achieve the following effect: when the cooling fan starts, the air outside the square pipe is drawn into the dust filter to clean the dust, and the cleaned air flows into the square pipe, where the cooling fan generates a cool airflow that blows into the power supply casing.

[0007] Preferably, two guide rods are fixedly connected to one side of the connecting plate.

[0008] The effect achieved by the above components is that the movement of the connecting plate drives the movement of the guide rod.

[0009] Preferably, two guide plates are fixedly connected to both sides of the square pipe, and the inner side of the guide plate is adapted to the guide rod.

[0010] The effect achieved by the above components is that the guide rod and the guide plate are compatible.

[0011] Preferably, side plates are fixedly connected to both sides of the square pipe, and sealing gaskets are fixedly connected to the side of the two side plates that are close to each other.

[0012] The effect achieved by the above components is to increase the sealing performance of the gasket.

[0013] Preferably, a cooling device is provided on one side of the power supply housing. The cooling device includes a base, one side of which is fixedly connected to the power supply housing, and a small circulating water pump is fixedly connected to one side of the base.

[0014] The effect achieved by the above components is to fix a small circulating water pump on the base.

[0015] Preferably, the output end of the small circulating water pump is fixedly connected to a cooling pipe.

[0016] The effect achieved by the above components is that the cooling pipe is fixed on the small circulating water pump.

[0017] Preferably, the arc surface of the cooling pipe is fixedly connected to a liquid injection pipe.

[0018] The effect achieved by the above components is to fix the injection pipe to the cooling pipe.

[0019] Preferably, a T-shaped plug is slidably connected to the inner side of the injection tube, and the T-shaped plug is made of rubber.

[0020] The effect achieved by the above components is that the T-shaped plug and the injection tube are compatible.

[0021] Preferably, two limiting blocks are fixedly connected to the arc surface of the cooling pipe, and heat dissipation plates are fixedly connected to both ends of the two limiting blocks.

[0022] The aforementioned components achieve the following effect: the limiting block is fixed on the heat sink, preventing the cooling pipe from shifting position.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a dustproof device is used to filter dust in the cooling airflow. When it is necessary to filter dust, the cooling fan is activated, and the dust filter filters the dust in the air. The dustproof device solves the problem of dust accumulating in key parts such as the fan blades and inside the power supply of traditional power supply exhaust cooling devices. The dust layer will hinder the transfer of heat, resulting in a decrease in heat dissipation efficiency. As the dust continues to accumulate, the heat dissipation effect will become worse and worse, and may even cause the power supply to overheat, causing malfunctions or damage.

[0025] In this invention, when enhanced heat dissipation is required, the T-shaped plug and the injection pipe are separated by a cooling device. Coolant is added into the cooling pipe through the injection pipe, and a small circulating water pump is started to circulate the coolant in the cooling pipe. This dissipates the heat absorbed by the heat sink from the power supply casing. The cooling device solves the problem of poor heat dissipation caused by traditional power supply exhaust cooling devices that rely solely on air cooling. Attached Figure Description

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a power supply exhaust and heat dissipation device, including a power supply housing 1, a dustproof device 2 on one side of the power supply housing 1, and a cooling device 3 on one side of the power supply housing 1.

[0032] The specific setup and function of its dustproof device 2 and cooling device 3 will be explained below.

[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the dustproof device 2 includes a square pipe 201, the outside of which is fixedly connected to the power supply casing 1. A cooling fan 202 is fixedly connected to the inside of the square pipe 201. Fixing blocks 203 are fixedly connected to both sides of the square pipe 201. An internally threaded pipe 204 is fixedly connected to one side of the fixing block 203. A bolt 205 is connected to the internal thread of the internally threaded pipe 204. A connecting plate 206 is slidably connected to the arc surface of the bolt 205. A dustproof net 207 is fixedly connected to the side of the two connecting plates 206 that are close to each other. This achieves the effect that when the cooling fan 202 is activated, the air outside the square pipe 201 is drawn towards the dustproof net 207 to purify the dust. The purified air flows into the square pipe 201 and, after passing through the cooling fan 202, generates a cool airflow that blows into the power supply casing 1. Two guide rods 208 are fixedly connected to one side of the connecting plate 206. This achieves the effect that the movement of the connecting plate 206 drives the movement of the guide rods 208. Two guide plates 209 are fixedly connected to both sides of the square pipe 201, and the inner side of the guide plate 209 is adapted to the guide rod 208. This achieves the effect of the guide rod 208 and the guide plate 209 being adapted to each other. Side plates 210 are fixedly connected to both sides of the square pipe 201, and sealing gaskets 211 are fixedly connected to the side of the two side plates 210 that are close to each other. This achieves the effect of the sealing gaskets 211 increasing the sealing performance.

[0034] Reference Figure 4 As shown, in this embodiment: the cooling device 3 includes a base 31, one side of which is fixedly connected to the power supply housing 1, and a small circulating water pump 32 is fixedly connected to one side of the base 31. This achieves the effect of fixing the small circulating water pump 32 to the base 31. A cooling pipe 33 is fixedly connected to the output end of the small circulating water pump 32. This achieves the effect of fixing the cooling pipe 33 to the small circulating water pump 32. A liquid injection pipe 34 is fixedly connected to the arc surface of the cooling pipe 33. This achieves the effect of fixing the liquid injection pipe 34 to the cooling pipe 33. A T-shaped plug 35, made of rubber, is slidably connected to the inner side of the liquid injection pipe 34. This achieves the effect of matching the T-shaped plug 35 and the liquid injection pipe 34. Two limiting blocks 37 are fixedly connected to the arc surface of the cooling pipe 33, and heat dissipation plates 36 are fixedly connected to both ends of the two limiting blocks 37. This achieves the effect of fixing the limiting blocks 37 to the heat dissipation plates 36, preventing the cooling pipe 33 from shifting position.

[0035] Working principle: Using dustproof device 2, when dust needs to be filtered from the cooling airflow, the operator first starts the cooling fan 202, causing external air to be drawn into the square pipe 201 towards the dustproof mesh 207 to purify the dust. The purified air flows into the square pipe 201, and the cooling fan 202 generates a cool airflow that blows into the power supply casing 1. Turning the bolt 205 disassembles the internal threaded pipe 204, allowing the dustproof mesh 207 to be removed from the square pipe 201, thus completing the cleaning and replacement of the dustproof mesh 207. When installing the dustproof mesh 207, the guide rod 208 slides into the guide plate 209, which lifts the bolt. The alignment efficiency of bolt 205 and internal thread ring is improved. After bolt 205 and internal thread ring are assembled, the position of dustproof net 207 is fixed by connecting plate 206. Sealing gasket 211 can effectively prevent dust from entering the square pipe through the gap between dustproof net 207 and square pipe 201. Through dustproof device 2, the problem of dust easily accumulating in key parts such as fan blades and power supply of traditional power supply exhaust heat dissipation devices is solved. Dust layer will hinder heat transfer, resulting in reduced heat dissipation efficiency. As dust continues to accumulate, the heat dissipation effect will become worse and worse, and may even cause the power supply to overheat, causing failure or damage.

[0036] When enhanced heat dissipation is required, the operator first separates the T-shaped plug 35 from the injection pipe 34 and adds coolant from the injection pipe 34 into the cooling pipe 33. At the same time, the small circulating water pump 32 is started to circulate the coolant in the cooling pipe 33, dissipating the heat absorbed by the heat sink 36 from the power supply casing 1. The cooling device 3 solves the problem of poor heat dissipation caused by traditional power supply exhaust cooling devices that rely solely on air cooling.
