Description

열전모듈을 이용한 냉온풍기{cold and hot air blower using thermoelectric module}Cold and hot air blower using thermoelectric module

본 발명은 열전모듈을 이용한 냉온풍기에 관한 것으로, 열전모듈에 의해 냉열 또는 온열을 공급하게 하며, 열전모듈에서 발생한 냉열과 온열의 상호 간섭을 줄여 효율을 높일 수 있도록 하는 열전모듈을 이용한 냉온풍기에 관한 기술이다.The present invention relates to a cold/hot air blower using a thermoelectric module, which supplies cold or warm heat by the thermoelectric module, and reduces the mutual interference between cold and warm heat generated in the thermoelectric module to increase efficiency. it is about technology

열전모듈은 양단에 직류 전압을 인가하면 열이 흡열부에서 발열부로 이동하게 되어 흡열부에서는 온도가 떨어지고 발열부에는 온도가 상승하게 됩니다. 이때 인가 전압의 극성을 바꿔주면 흡열부와 발열부는 서로 바뀌게 되고 열의 흐름이 반대가 되게 됩니다.When a DC voltage is applied to both ends of the thermoelectric module, heat moves from the heat absorbing part to the heating part. At this time, if the polarity of the applied voltage is changed, the heat absorbing part and the heat generating part are exchanged and the flow of heat is reversed.

이러한 열전모듈을 이용하여 냉정수기, 공기정화기, 차량용 냉장고, 화장품 보관 용기 및 냉온풍기 등 각종 전자제품에 이용되고 있다.These thermoelectric modules are being used in various electronic products such as cold water purifiers, air purifiers, vehicle refrigerators, cosmetic storage containers, and hot and cold blowers.

그러나, 열전모듈에서 양면에 온열과 냉열이 동시에 발생하므로 둘 중 하나를 선택하여 사용시 상호 간섭을 줄여 효율을 최대한 높일 수 있는 방법이 요구된다.However, since hot and cold heat are generated on both sides of the thermoelectric module at the same time, there is a need for a method that can maximize efficiency by reducing mutual interference when selecting one of the two and using it.

Since the following description and the accompanying drawings are presented for a general understanding of the present invention, the technical scope of the present invention is not limited thereto. In addition, detailed descriptions of well-known configurations and functions that may unnecessarily obscure the gist of the present invention will be omitted.

도 1은 본 발명의 실시예에 따른 열전모듈을 이용한 냉온풍기의 구성도이다.1 is a block diagram of a cold/hot air blower using a thermoelectric module according to an embodiment of the present invention.

도 1을 참조하면, 본 발명은 본체(100), 열전모듈(200), 팬(300) 및 흡열재(400)가 포함되어 이루어진다.Referring to FIG. 1 , the present invention includes a body 100 , a thermoelectric module 200 , a fan 300 , and a heat absorbing material 400 .

본체(100)는 해당 기기의 외부 케이스를 나타낸 것으로 상기 열전모듈(200), 팬(300) 및 흡열재(400)를 수용할 수 있다. 상기의 본체(100)는 사용 용도에 따라 휴대성이 높은 도 1의 손선풍기 또는 도 2의 선풍기 외형 형태로 형성할 수 있다.The main body 100 represents an external case of the device and may accommodate the thermoelectric module 200 , the fan 300 , and the heat absorbing material 400 . The main body 100 may be formed in the external shape of the hand fan of FIG. 1 or the fan of FIG. 2 with high portability depending on the intended use.

상기 열전모듈(200)은 상기 본체(100) 내부에 설치되어 전류가 인가되면 발열되는 발열부와, 냉각되는 냉각부로 구성된다. 여기서 열전모듈(200)은 전류의 극성을 바꾸면 상기 발열부와 냉각부는 상호 반대가 되게 할 수 있으며 외부의 변환 스위치를 더 형성할 수 있다.The thermoelectric module 200 is installed inside the main body 100 and includes a heating part that generates heat when a current is applied and a cooling part that is cooled. Here, in the thermoelectric module 200, if the polarity of the current is changed, the heating unit and the cooling unit may be opposite to each other, and an external conversion switch may be further formed.

상기 팬(300)은 상기 열전모듈(200) 측에 설치되는 방향에 따라 상기 발열부의 온열 또는 상기 냉각부의 냉열을 외부로 배출하게 되어 냉풍기 또는 온풍기로 사용할 수 있게 되는 것이다.The fan 300 discharges the warm heat of the heating unit or the cold heat of the cooling unit to the outside according to the direction in which it is installed on the thermoelectric module 200 side, so that it can be used as a cooling fan or a hot air fan.

상기 흡열재(400)는 상기 팬(300)과 반대방향으로 상기 열전모듈(200)에 설치되어 상기 발열부의 온열 또는 상기 냉각부의 냉열을 흡수하게 된다. 이렇게 상기 흡열재(400)가 상기 팬(300)의 반대 방향에서 온열 또는 냉열을 흡수함에 따라 상기 팬(300)에서 송풍하는 냉풍 또는 온풍의 효율을 극대화할 수 있다. 여기서 흡열재(400)는 고분자를 주재료로 하는 비금속 물질로 제작할 수 있다.The heat absorbing material 400 is installed in the thermoelectric module 200 in the opposite direction to the fan 300 to absorb the warm heat of the heat generating unit or the cold heat of the cooling unit. In this way, as the heat absorbing material 400 absorbs hot or cold heat from the opposite direction of the fan 300 , the efficiency of cold air or warm air blown by the fan 300 can be maximized. Here, the heat absorbing material 400 may be made of a non-metal material having a polymer as a main material.

한편, 상기 열전모듈(200)에는 한측면에 열전도가 높은 알루미늄판, 다른 측면에 비금속 흡열재 또는 금속 방열재(500)를 단일 또는 복합으로 적용하여 열전모듈(200)에서 발생한 냉열 또는 온열을 팬(300)과 비금속 흡열재 및 금속 방열재에 신속하게 전달할 수 있게 된다. 여기서 금속 방열재(500)는 알루미늄을 주재료로 하는 금속재로 제작할 수 있다.On the other hand, in the thermoelectric module 200, an aluminum plate with high heat conduction on one side and a non-metal heat absorbing material or a metal heat dissipating material 500 on the other side are applied singly or in combination to cool or heat generated in the thermoelectric module 200 as a fan. 300 and the non-metallic heat absorbing material and the metallic heat dissipating material can be quickly transferred. Here, the metal heat dissipation material 500 may be made of a metal material having aluminum as a main material.

이상과 같이 본 발명은 열전모듈을 이용한 냉온풍기의 기본적인 기술적인 사상으로 하고 있음을 알 수 있으며, 이와 같은 본 발명의 기본적인 사상의 범주내에서, 당업계의 통상의 지식을 가진 자에게 있어서는 다른 많은 변형이 가능함은 물론이다.As described above, it can be seen that the present invention is based on the basic technical idea of a cold/hot air blower using a thermoelectric module. Of course, variations are possible.
