Description

Technical Field

[0001] The invention relates to the technical field of mini computer heat dissipation, in particular to an ion wind generating structure and an auxiliary heat dissipation method thereof. Background Art

[0002] Ion wind (corona wind) is based on the principle of corona discharge. Under the action of high voltage, charged particles flow at high speed from the tip electrode to the collector electrode, thereby driving the air to form a directional flow. The high-speed flow of charged particles drives the air to generate wind. At present, the mini computer hosts on the market mainly use heat pipes and air cooling to dissipate heat. Since the size of mini desktop computer hosts needs to be smaller, their internal space is usually very small, the air intake is insufficient, and it is impossible to install more than two air-cooled radiators. The heat dissipation effect of one air-cooled radiator is not ideal; for larger mini desktop computer hosts, more than two air-cooled radiators can be installed, but there will be a lot of noise caused by the rotation and vibration of the fan. Summary of the invention

[0003] In order to solve the above technical problems of unsatisfactory heat dissipation effect and large noise generated by multiple fans, the present invention provides an ion wind generating structure and an auxiliary heat dissipation method thereof, and the specific scheme is as follows:

[0004] An ion wind generating structure comprises an electrode unit and an insulating member, wherein the electrode unit comprises at least one transmitting electrode and at least two receiving electrodes, wherein one of the receiving electrodes is a heat dissipation fin, and at least one of the receiving electrodes is a metal mesh, and the insulating member is a fan cover. At least one tip is designed on each side of the transmitting electrode, the transmitting electrode is arranged in a through slot provided on the fan cover, and the metal mesh is arranged in the through slot provided on the fan cover. The transmitting electrode is separated from the heat dissipation fin and the metal mesh by a local structure of the fan cover, and the fan cover adopts a central through design from one end facing the heat dissipation fin to the other end thereof, an A-zone ion wind is formed between the upper part of the heat dissipation fin, the fan cover and the transmitting electrode, and a B-zone ion wind is formed between the fan cover, the transmitting electrode, the metal mesh and the fan.

[0005] Preferably, plastic sheets are fixed on the upper and lower surfaces of the emitting electrode, and a plurality of the emitting electrodes 1 are stacked up and down, and the thickness of the emitting electrode is 0.1 mm to 0.4 mm.

[0006] Preferably, a plurality of the metal meshes are stacked up and down, and the thickness of the metal meshes is 0.5 mm to 1 mm.

[0007] Preferably, the emitting electrode is arranged perpendicularly to the metal mesh, and the emitting electrode 1 is arranged parallel to the heat dissipation fins.

[0008] Preferably, the central passage area of ​​the fan cover is divided into a multi-layer isolation design, and each layer of isolation space is used to install an emitting electrode.

[0009] Preferably, the transmitting electrode is connected to the positive pole of the transformer, and the heat dissipation fins and the receiving electrode are grounded.

[0010] An ion wind generating structure assists heat dissipation method, in which several tips of one wing of an emitting electrode emit high-speed charged particles that pass through a central through area of ​​a fan cover and are captured by heat dissipation fins, and low-temperature air around the emitting electrode flows toward the heat dissipation fins to accelerate the heat on the heat dissipation fins and dissipate from the gaps between the fins; the tip of one wing of the emitting electrode emits high-speed charged particles that pass through a central through area of ​​a fan cover and are captured by a metal mesh, and low-temperature air around the emitting electrode flows toward the metal mesh, and the flowing low-temperature air is sucked into the air inlet of the fan and merges with the low-temperature air entering from the outside to enhance the airflow velocity and flow rate in the fan, and is discharged along the internal gaps of the fan and the gaps between the heat dissipation fins to take away the heat.

[0011] Preferably, the ion wind in zone B is blown toward the air inlet of the fan, enters the interior of the fan under the restriction of the cavity formed by the fan cover and the fan, turns around and is discharged from the gaps between the heat dissipation fins.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention sets two through grooves on the insulating fan cover, sets the transmitting electrode in one of the through grooves, sets a receiving electrode (heat sink fin) and at least one other receiving electrode (metal mesh) at an appropriate distance on both sides of the transmitting electrode, and when the voltage of the transmitting electrode end is increased, the tip of the transmitting electrode emits high-speed charged particles to both sides based on the corona discharge principle to form ion winds in areas A and B. The ion wind in area A directly takes away the heat of the heat sink fins, and the ion wind in area B merges with the low-temperature air entering from the outside to enhance the air velocity and flow rate in the fan, and together discharge the heat from the heat source from the gaps in the heat sink fins. The ion wind structure heat dissipation method of the present invention does not increase the number of fans or the noise, but adds a heat dissipation channel, while also increasing the airflow rate of the fan, thereby improving the overall heat dissipation efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Refer to the following Figure 1-4 An ion wind generating structure of an embodiment of the present application is specifically described, including an electrode unit and an insulating member, the electrode unit including at least one transmitting electrode 1 and at least two receiving electrodes, one of the receiving electrodes is a heat sink 2, at least one receiving electrode is a metal mesh 3, the insulating member is a fan cover 6, at least one tip is designed on each side of the transmitting electrode 1, the transmitting electrode 1 is arranged in a through groove opened on the fan cover 6, the metal mesh 3 is arranged in the through groove opened on the fan cover 6, the transmitting electrode 1 is separated from the heat sink 2 and the metal mesh 3 by the local structure of the fan cover 6, the fan cover 6 adopts a central through design from one end facing the heat sink 2 to the other end, the A zone ion wind is formed by the upper part of the heat sink 2, the fan cover 6 and the transmitting electrode 1, and the B zone ion wind is formed by the fan cover 6, the transmitting electrode 1, the metal mesh 3 and the fan 7.

[0022] The electrode unit includes a receiving electrode with a heat dissipation fin 2 made of an aluminum alloy as one end. In order to increase the ion wind volume, multiple transmitting electrodes 1 can be stacked. Each transmitting electrode 1 is separated by a plastic sheet 5 and fixed in the through slot of the fan cover 6. The tips of the two sides of the transmitting electrode 1 are just placed in the middle through area inside the fan cover 6. There are several tips. The two ends of the transmitting electrode 1 exposed outside the through slot are used to conduct the voltage power supply. The metal mesh 3 is used as the receiving electrode. In order to capture more charged particles of the transmitting electrode 1 and increase the ion wind volume, the number of metal meshes 5 stacked is the same as that of the transmitting electrode 1. After stacking, they are placed in another through slot of the fan cover 6. The top cover and the bottom surface of the fan cover 6 are hollow. The structure on the left side of the fan cover 6 well separates the heat dissipation fin 2, the transmitting electrode 1 and the receiving electrode (metal mesh 3) and the top surface of the fan 7, effectively avoiding the arc phenomenon, and also facilitating the ion wind to move to the heat dissipation fin 2 and the air inlet 8 of the fan 7, forming the A area ion wind on the left side of the transmitting electrode 1 and the B area ion wind on the right side.

[0023] According to an embodiment of the present application, plastic sheets 5 are fixed on the upper and lower surfaces of the emitting electrode 1, and a plurality of emitting electrodes 1 are stacked up and down, and the thickness of the emitting electrode 1 is 0.1 mm to 0.4 mm.

[0024] The plastic sheet 5 is adhered to the upper and lower surfaces of the emitting electrode 1, and its thickness is twice that of the emitting electrode 1. The function of the sheet is to avoid arcing between multiple superimposed emitting electrodes 1. It is also possible to set only one emitting electrode 1 and one receiving electrode (metal mesh 3). In order to increase the ion air volume, multiple emitting electrodes 1 and multiple receiving electrodes (metal mesh 3) can also be stacked and set. When multiple are set, the hollow area between the top cover and the bottom surface of the fan cover 6 on both sides of the emitting electrode 1 is separated by layers, and an emitting electrode 1 is placed on each layer. A receiving electrode (metal mesh 3) is set at the through groove corresponding to each layer of the emitting electrode 1, which is beneficial to increase the ion air volume.

[0025] According to an embodiment of the present application, a plurality of metal meshes 3 are stacked up and down, and the thickness of the metal meshes 3 is 0.5 mm to 1 mm.

[0028] The number of fins of the heat dissipation fin 2 is four to six times the tip of the emitting electrode 1. Each fin of the heat dissipation fin 2 is parallel to the tip. This many-to-one relationship utilizes the fins to capture charged particles to form ion wind; the metal mesh 3 and the tip of the emitting electrode 1 also have a many-to-one relationship, and the fins are utilized to capture charged particles to form ion wind.

[0029] According to one embodiment of the present application, the central passage area of ​​the fan cover 6 is divided into a multi-layer isolation design, and each layer of isolation space is used to install an emitting electrode 1. The electric particles of each layer of the emitting electrode 1 can be emitted toward the heat dissipation fins 2 and the metal mesh without interference from other layers, which is conducive to forming a multi-layer ion wind.

[0030] According to an embodiment of the present application, the transmitting electrode 1 is connected to the positive electrode of the transformer 4, and the heat sink fin 2 and the receiving electrode are grounded.

[0031] The adjustable voltage range of transformer 4 is 1kv to 10kv, and the size of ion wind is controlled by adjusting the voltage.

[0032] An ion wind generating structure assists heat dissipation method, wherein several tips of one wing of the emitting electrode 1 emit high-speed charged particles that pass through the middle through area of ​​the fan cover 6 and are captured by the heat dissipation fins 2, and the low-temperature air around the emitting electrode 1 flows toward the heat dissipation fins 2 to accelerate the heat on the heat dissipation fins 2 to dissipate from the gaps between the fins; the tip of one wing of the emitting electrode 1 emits high-speed charged particles that pass through the middle through area of ​​the fan cover 6 and are captured by the metal mesh 3, and the low-temperature air around the emitting electrode 1 flows toward the metal mesh 2, and the flowing low-temperature air is sucked into the air inlet 8 of the fan 7 and merges with the low-temperature air entering from the outside to enhance the air flow velocity and flow rate in the fan 7, and is discharged along the internal gaps of the fan 7 and the gaps between the heat dissipation fins 2 to take away the heat. The structural device of the present application is suitable for use on a mini computer host, and the components below the heat dissipation fins 2 and the fan 7 are the heat pipes, heat conductive sheets and heat-generating chips commonly used for mini computer heat dissipation, such as CPU, storage components, wifi modules, etc. The heat dissipation of the present application is the heat dissipation of the mini computer host.
