Description

Cooling fan using a Peltier module

[0001] The present invention relates to a cooling fan, and in particular, to a cooling fan that cools a heat sink using Peltier properties and blows out cold air using a fan motor.

[0002] Generally, in a cooling system, the evaporator, condenser, compressor, and expansion valve are connected by pipes, and the temperature is reduced by compressing and expanding the refrigerant circulating inside while exchanging heat with the indoor air.

[0003] The principle of such conventional cooling devices is based on compressing the refrigerant by driving a compressor. That is, the refrigerant is sucked in and compressed by the compressor, and then sent to the condenser in a gaseous state at high temperature and high pressure (approx. 70°C, 15 kgf / ㎠).

[0004] The refrigerant sent from the compressor is forcibly cooled and liquefied, and the liquefied refrigerant flows into the expansion valve. In the expansion valve, the high-pressure liquid refrigerant rapidly expands to become a low-temperature, low-pressure mist-like refrigerant, which enters the evaporator. The refrigerant in the evaporator then absorbs heat from the surrounding air to become a gaseous refrigerant, which returns to the compressor.

[0005] In this way, the refrigerant circulates while repeating the refrigerant cycle and performs cooling action.

[0006] However, these conventional cooling devices must use a compressor, which increases manufacturing costs and has the disadvantage of consuming a very large amount of electricity (kw / day). In particular, large-capacity so-called stand-type air conditioners require installing the condenser outside the building and performing piping work with the main unit installed inside the building, which not only requires a lot of work and cost for installation but also has the disadvantage of being inconvenient to move. Additionally, because they use a specific refrigerant in a gaseous state, they have the disadvantage of causing inconvenience and a significant economic burden due to the need to replenish the refrigerant.

[0007] In addition, the use of refrigerant gas is regulated because if the above refrigerant is released into the atmosphere, it pollutes the environment.

[0008] In particular, since the use of cooling devices increases costs due to electricity consumption, cooling fans that generate cold air using refrigerant packs filled with refrigerant or ice and circulate that cold air have recently been developed and are being used.

[0009] However, these air coolers are cumbersome because they require a continuous supply of refrigerant packs or ice, and they also have the problem of not cooling properly as the water evaporates and the indoor humidity rises. In addition, since water is used, there are problems such as the proliferation of bacteria.

[0014] The present invention was devised to solve the above-mentioned problems, and aims to provide a cooling fan that cools a heat sink using Peltier characteristics and blows out cold air using a fan motor.

[0015] The purpose of the present invention is to provide a cooling fan capable of exhibiting excellent cooling efficiency by generating cold air through a fan motor using cold air from a Peltier element and cooling hot air using a water-cooling method to maintain the cooling effect, thereby smoothly releasing the hot air generated from the Peltier element and allowing cold air from the Peltier element to be generated more smoothly.

[0016] The purpose of the present invention is to provide a cooling fan capable of maintaining a cooling effect utilizing Peltier characteristics for a long period of time by increasing the cooling retention effect of the cooling water through water cooling of the hot side of the Peltier element to maintain the Peltier cooling effect.

[0017] The purpose of the present invention is to provide a cooling fan that reduces the inconvenience and economic burden associated with replenishing wasted refrigerant by not using a specific refrigerant in a gaseous state, and reduces manufacturing costs and power consumption (kW / day) by using a Peltier element that utilizes Peltier characteristics.

Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0019] The features of a cooling fan using a Peltier module according to the present invention for achieving the above-mentioned purpose include: first and second Peltier elements (10a)(10b) having a first electrode plate (11) and a second electrode plate (12), wherein through polarity conversion, the temperature of the first electrode plate (11) is lowered by heat absorption and the temperature of the second electrode plate (12) is raised by heat generation; a cooling heat dissipation plate (30) disposed in the inner center where the first electrode plate (11) of the first and second Peltier elements (10a)(10b) is located, for dissipating cold air generated from the first electrode plate (11) of the first and second Peltier elements (10a)(10b); and a second Peltier element (10a)(10b) disposed on the outer side where the second electrode plate (12) of the first and second Peltier elements (10a)(10b) is located. It may include a cooling water passage (60a)(60b) for dissipating heat generated from an electrode plate (12), a fan motor (20) coupled to the lower end of the cooling heat dissipation plate (30) to move the cold air dissipated by the cooling heat dissipation plate (30) to one side, an exhaust fan (40) for exhausting the cold air moved from the fan motor (20) to the outside through a discharge port, a water pump (51) that circulates cooling water (50) through a pipe (80) and introduces the circulating cooling water (50) into the cooling water passage (60a)(60b) to cool the heat generated from the second electrode plate (12) located in the cooling water passage (60a)(60b), and a vaporization filter (70) that cools the cooling water (50) flowing out from the cooling water passage (60a)(60b) and heat exchanges the external air drawn in and passed through by the exhaust fan (40) into cold air. there is.

[0020] Preferably, the cooling water passages (60a) and (60b) are configured as moving grooves having a moving path through which the cooling water (50) moves, and can be integrally formed on both sides of the cooling heat sink (30).

[0021] Preferably, the water pump (51) may be characterized by cooling the heat generated in the second electrode plate (12) located in the cooling water passage (60a)(60b) in a water-cooling manner.

[0022] As explained above, the cooling fan using the Peltier module according to the present invention has the following effects.

[0023] First, the cold air coming from the Peltier element is used to generate cold air through a fan motor, and the hot air is cooled by water cooling to maintain the cooling effect. This allows the hot air generated from the Peltier element to be released smoothly, thereby enabling the cold air coming from the Peltier element to be generated more smoothly, which has the effect of exhibiting excellent cooling efficiency.

[0024] Second, to maintain the Peltier cooling effect, the cooling water cools the hot side of the Peltier element in a water-cooling manner, thereby enhancing the cooling retention effect of the water and enabling the cooling effect utilizing Peltier properties to be maintained for a long period of time.

However, the present invention is not limited to the embodiments disclosed below and can be implemented in various different forms.

[0037] FIG. 1 is a schematic diagram showing the configuration of a cooling fan using a Peltier module according to an embodiment of the present invention. The cooling fan shown in FIG. 1 is according to one embodiment, and its components are not limited to the embodiment shown in FIG. 1, and some components may be added, changed, or deleted as needed.

[0038] As illustrated in FIG. 1, the cooling fan of the present invention may include first and second Peltier elements (10a)(10b), a cooling heat sink (30), cooling water passages (60a)(60b), a fan motor (20), an exhaust fan (40), and an evaporation filter (70). It also includes a water pump (51) that circulates cooling water (50) through a pipe (80).

[0039] The first and second Peltier elements (10a) and (10b) may include P-type and N-type thermoelectric semiconductor elements to enable heat absorption through polarity conversion using the Peltier effect, and a first electrode plate (11) and a second electrode plate (12) that receive power with positive and negative polarity conversion. Accordingly, the temperature of the first and second Peltier elements (10a) and (10b) is lowered by heat absorption at the first electrode plate (11), and the temperature is raised by heat generation at the second electrode plate (12).

[0040] The above first and second Peltier elements (10a) and (10b) can be installed at the bottom of the air cooler and operated.

[0041] The above cooling heat sink (30) is positioned in the inner center where two first electrode plates (11), whose temperature has been lowered by the heat absorption action of the first and second Peltier elements (10a) (10b), are located, thereby cooling the cold air generated from the first electrode plates (11) of the first and second Peltier elements (10a) (10b).

[0042] At this time, the cooling heat sink (30) can be installed in close contact with the first electrode plate (11).

[0043] The above cooling water passages (60a) (60b) are each positioned on the outer side where the second electrode plate (12), whose temperature has been raised by the heat absorption action of the first and second Peltier elements (10a) (10b), is located, and the heat generated from the second electrode plate (12) of the first and second Peltier elements (10a) (10b) is dissipated by the cooling water (50) that flows in and moves.

[0044] FIG. 2 is a product photograph showing the front and back of the cooling heat sink and cooling water passage of FIG. 1. As shown in FIG. 2, the cooling water passage (60a)(60b) is composed of a moving groove having a moving path through which the cooling water (50) moves, and can be integrally formed on both sides of the cooling heat sink (30). At this time, the moving path of the cooling water (50) in the cooling water passage (60a)(60b) can be configured as a path passing through the second electrode plate (11).

[0045] The above fan motor (20) is coupled to the lower part of the cooling heat sink (30) and moves the cold air cooled by the cooling heat sink (30) to one side.

[0046] The above exhaust fan (40) exhausts the cold air transferred from the fan motor (20) to the outside through the discharge port.

[0047] The above water pump (51) circulates the cooling water (50) contained in the water tank through the pipe (80) and introduces the circulating cooling water (50) into the cooling water passage (60a)(60b) to cool the heat generated in the second electrode plate (12) located in the cooling water passage (60a)(60b) in a water-cooling manner.

[0048] At this time, the above-mentioned water tank is equipped with an overflow pipe that discharges the cooling water (50) overflowing from within, and the end of the overflow pipe can be connected to a recovery tank that stores the cooling water (50).

[0049] The above vaporization filter (70) cools and circulates the heated cooling water (50) flowing out of the cooling water passages (60a) (60b). The above vaporization filter (70) has an absorbent property to heat exchange the external air drawn in and passed through by the exhaust fan (40) into cold air.

[0050] Through this configuration, the air cooler maintains the cooling effect through the two first electrode plates (11) whose temperatures are lowered in the first and second Peltier elements (10a) (10b), and the hot parts of the second electrode plate (12) whose temperatures are raised can be cooled with cooling water (50), thereby increasing the cooling effect.

[0051] That is, by utilizing the property that the first electrode plate (11) of the first and second Peltier elements (10a) (10b) generates cold air and the second electrode plate (12) generates hot air, the cold air is guided to the discharge port by the cooling heat sink (30) through the fan motor (20), and the cold air thus guided is exhausted to the outside through the exhaust fan (40). Then, the hot air is cooled by the cooling water (50) in a water-cooling manner, and the heated cooling water (50) is cooled by passing through the vaporization filter (70).

[0052] Meanwhile, looking at the configuration of the air cooler shown in FIG. 1 and FIG. 3a and 3b, a Peltier module consisting of first and second Peltier elements (10a) (10b), a fan motor (20), a cooling heat sink (30), and cooling water passages (60a) (60b) is configured in a position perpendicular to the exhaust fan (40). Thus, when cold air rises from the Peltier module located below the exhaust fan (40), the exhaust fan (40) changes the direction of the cold air rising from below vertically and moves it to the discharge port.

[0053] However, the configuration of the air cooler shown in FIG. 1 and FIG. 3a and 3b is merely one example for easy explanation and is not limited thereto.

[0054] That is, a Peltier module composed of first and second Peltier elements (10a)(10b), a fan motor (20), a cooling heat sink (30), and a cooling water passage (60a)(60b) can be configured in a position that is horizontal to the exhaust fan (40). In this configuration, when cold air moves horizontally from the Peltier module located at the front end of the exhaust fan (40), the exhaust fan (40) can move the horizontally moving cold air to the discharge port without changing its direction. In this case, the cold air generated from the Peltier module can be moved directly to the exhaust fan (40) without changing its direction, thereby reducing wasted cold air and further increasing the cold air effect.

[0055]

[0056] The operation of the air cooler according to the present invention configured as described above will be explained in detail with reference to the attached drawings as follows. Reference numerals identical to those in FIG. 1 refer to identical components that perform the same function.

[0057] First, a Peltier module including first and second Peltier elements (10a) and (10b) is installed at the bottom of a cooling fan to operate the Peltier module.

[0058] Then, the cold air generated from the first electrode plates (11) of the first and second Peltier elements (10a) (10b) is cooled through a cooling heat dissipation plate (30) positioned in the inner center where the two first electrode plates (11), whose temperature has been lowered by the heat absorption action of the first and second Peltier elements (10a) (10b), are positioned, and cold air is discharged through the air blower outlet.

[0059] FIG. 3a is a drawing for explaining the path of cold air movement in a cooling fan according to the present invention. As shown in FIG. 3a, cold air generated from the first electrode plate (11) is moved in the direction of the discharge port by the fan motor (20).

[0060] Next, a cooling water passage (60a)(60b) is arranged on the outer side where the second electrode plate (12), whose temperature has been raised by the heat absorption action of the first and second Peltier elements (10a)(10b), is located, and the heat generated from the second electrode plate (12) of the first and second Peltier elements (10a)(10b) is dissipated by the cooling water (50) that flows in and moves.

[0061] That is, in order for the Peltier module to normally generate cold air, the heat generated from the second electrode plate (12) of the first and second Peltier elements (10a) (10b) must be cooled smoothly. To this end, cooling water (50) is introduced into the cooling water passage (60a) (60b) to cool the heat generated from the second electrode plate (12) by a water-cooling method.

[0062] FIG. 3b is a drawing for explaining the movement path of cooling water through a cooling water passage in a cooling fan according to the present invention. As shown in FIG. 3b, the cooling water (50) that moves through the movement path secured by a pipe (or silicone tube) (80) cools the heat generated from the second electrode plate (12) and passes through a vaporization filter (70) to be received back into the water tank.

[0063] At this time, the coolant (50) passes through the vaporization filter (70), and the heated coolant (50) cools down due to the heat of vaporization. In addition, as time passes during operation, the coolant (50) decreases and becomes warmer, so the coolant can be replaced with cold water after about 4 hours.

[0064] Through this operation, the cooling effect of the Peltier module is maintained in the air cooler, and the hot part on the opposite side of the Peltier module can be cooled with cooling water, thereby maintaining cooling capacity and increasing the cooling effect.
