본 발명은 알루미늄재의 냉매튜브와 헤더, 방열핀등으로 이루어진 열교환기용 코어를 제조함에 있어서, 상기 코어를 제조하기 위한 알루미늄소재에 접합재인 클래드(Clad)를 도포하도록 하고 상기 클래드재에 의하여 상기 코어의 각 부품들이 브레이징시 견고하게 접합되도록 하며, 상기 클래드재는 알루미늄 보다 융점이 낮은 Al-Si로 이루어진 재료를 분말화하고 이 분말에 분말상태의 플럭스(Flux)를 혼합한 다음, 상기 혼합물을 와이어상으로 제조하여 이루어지도록 하며 상기 알루미늄 소재를 압연할 때 상기 와이어상의 혼합물을 융사하도록하여 상기 열교환기의 코어제조를 원활하게 하면서 견고한 접합이 이루어지도록 한 열교환기의 코어제조방법과 접합재의 도포방법에 관한 것이다.In the present invention, in manufacturing a core for a heat exchanger made of an aluminum refrigerant tube, a header, a heat radiation fin, and the like, to apply a clad (clad) as a bonding material to the aluminum material for manufacturing the core and each of the core by the clad material The parts are firmly bonded during brazing, and the cladding material powders a material made of Al-Si having a lower melting point than aluminum, mixes powdered flux with the powder, and then prepares the mixture in a wire form. When the aluminum material is rolled to melt the mixture on the wire to facilitate the core manufacturing of the heat exchanger, and to provide a solid bonding method for the core manufacturing method of the heat exchanger and the coating method of the bonding material.

일반적으로 에어콘의 방열기등으로 이용되는 콘덴서나 증발기 등의 열교환기는 대체로 알루미늄등으로 된 헤더를 설치하고 있으며 이 헤더에는 다수의 방열핀이 설치되는 여러개의 냉매순환용 냉매튜브를 삽입설치하고 상기 냉매튜브를 따라 냉매가 순환되면서 방열작용을하여 열교환이 이루어지도록 구성되어 있었으며, 상기 각 부품들은 대체로 알루미늄 재료를 소재로하여 제조되고 있었다.In general, a heat exchanger such as a condenser or an evaporator, which is used as a radiator for an air conditioner, generally includes a header made of aluminum, and a plurality of coolant circulation refrigerant tubes having a plurality of heat dissipation fins are inserted into the header. As a result, the refrigerant was circulated to perform heat dissipation to perform heat dissipation. Each of the parts was generally made of aluminum.

한편, 상기와 같이 구성된 종래의 열교환기용 코어는 도 1에서와 같이 알루미늄을 소재로하여 냉매튜브와 방열핀을 각각 성형하여 제조한 다음, 상기 냉매튜브들을 설치하기 위한 알루미늄재 헤더를 압출이나 압연방식으로 제조하고 상기 제조된 헤더등의 각 부품이 압출 또는 압출 또는 압출 또는 압연된 상에서 융점이 낮은 클래드재를 압연하여 상기 각 부품들의 일측면에 접합시키며, 이 클래드재가 접합된 상태에서 상기 헤더와 냉매튜브, 방열핀들을 형상에 따라 제조하여 조립한 다음, 이들의 조립부에 물과 혼합된 플럭스를 도포하고 이 상태에서 상기 조립된 코어를 브레이징로 넣어 브레이징하도록 하므로써 상기 코어를 제조하도록 구성되어 있었다.Meanwhile, the conventional heat exchanger core configured as described above is manufactured by molding a coolant tube and a heat dissipation fin based on aluminum as shown in FIG. 1, and then extrudes or rolls an aluminum header for installing the coolant tubes. After manufacturing, each part of the manufactured header and the like is extruded or extruded or extruded or rolled, and the low melting point clad material is rolled and bonded to one side of each of the parts, the header and the refrigerant tube in the state where the clad material is joined After manufacturing and assembling the heat dissipation fins, the cores were manufactured by applying flux mixed with water to their assembly parts and brazing the assembled cores in this state.

그러나, 상기와 같은 종래의 코어제조방법은 상기 클래드재를 코어의 부품들 소재를 압연할 때 이들과 함께 압연하도록 하므로써 이 클래드재의 압연공정이 필요하게 되었으며, 이에 따른 작업공수가 많이 들게 되는 폐단이 있었고, 상기 클래드재가 압출 또는 압출 또는 압출 또는 압연된 상태에서 상기 각 부품들을 제조한 상태에서 이들의 접합부에 상기 물과 혼합되는 플럭스를 도포하도록 하고 있었기 때문에 상기 플럭스가 불필요한 부분에 까지 도포되어 플럭스의 낭비가 초래되는 폐단이 있었으며, 상기 플럭스의 도포상태가 일률적으로 균일하지 못하여 접합상태가 불량하게 되는 결점이 있었다.However, in the conventional core manufacturing method as described above, the cladding material is rolled together with them when rolling the material of the core parts, thereby requiring a rolling process of the cladding material. Since the clad material was extruded or extruded or extruded or rolled, the flux mixed with the water was applied to their joints while the parts were manufactured. There was a closed end resulting in waste, and there was a defect in that the application state of the flux was uniformly uneven and the bonding state was poor.

또한, 상기와 같은 종래의 것은 상기 플럭스가 불필요한 부분에 까지 도포되므로써 코어의 외형이 미려하게 되지 못하는 폐단이 있었으며, 상기 플럭스가 견고하게 접합되지 못하여 부수러기등이 발생될 경우 이 부수러기가 비산되는 점등의 문제점이 있었다.In addition, the conventional one has a closed end where the external appearance of the core cannot be made beautiful by applying the flux to an unnecessary portion, and when the flux is not firmly bonded and breakage occurs, the breakage is scattered. There was a problem of lighting.
