자동차용 라디에이터{RADIATOR FOR VEHICLE}Radiator for Cars {RADIATOR FOR VEHICLE}

본 고안은 자동차용 라디에이터에 관한 것으로서, 열교환기의 튜브가 알루미늄 발포금속으로 이루어진 자동차용 라디에이터에 관한 것이다.The present invention relates to an automobile radiator, and relates to an automobile radiator, the tube of the heat exchanger is made of aluminum foam metal.

도 1을 참조하면, 일반적으로 자동차용 라디에이터(3)는 엔진 룸 전방으로 장착되며, 서모스탯(2)의 작동에 의해 엔진(1)에서 토출되는 냉각수가 유입되고, 외기에 의해 고온의 냉각수를 냉각시켜 다시 워터 펌프(4)를 통해 엔진(1)에 공급되도록 하는 것으로서, 그 구조는 도 2에 도시된 바와같이 크게 상부탱크(5)와 열교환기(6)와 하부탱크(7)로 구분되며 서로 연통되어 있다.Referring to FIG. 1, a radiator 3 for a vehicle is generally mounted in front of an engine room, and cooling water discharged from the engine 1 is introduced by the operation of the thermostat 2, and high temperature cooling water is introduced by outside air. As it is cooled and supplied to the engine 1 through the water pump 4 again, the structure is divided into the upper tank 5, the heat exchanger 6 and the lower tank 7 as shown in FIG. And communicate with each other.

도 2를 참조하면, 상기 라디에이터의 열교환기(6)는 냉각수가 흐르는 튜브(8)와 상기 튜브의 열교환 효율을 향상시키기 위한 핀(9)을 포함한다.Referring to FIG. 2, the heat exchanger 6 of the radiator includes a tube 8 through which coolant flows and a fin 9 for improving the heat exchange efficiency of the tube.

그러나 상기와 같은 종래의 라디에이터는 열교환 효율을 향상시키기 위해 튜브 둘레에 핀을 부착해야 하기 때문에 제작이 어렵고, 비용이 많이 드는 문제점이 있었다.However, the conventional radiator as described above has a problem that it is difficult to manufacture and costly because a fin must be attached around the tube in order to improve heat exchange efficiency.

따라서, 본 고안의 목적은 열교환기의 튜브가 발포금속으로 이루어져 튜브 둘레에 핀을 별도로 구비하지 않아도 열교환 효율이 충분한 자동차용 라디에이터를 제공하는 것이다.Accordingly, an object of the present invention is to provide a radiator for automobiles having sufficient heat exchange efficiency even though the tubes of the heat exchanger are made of foamed metal and do not have fins separately around the tubes.

상기와 같은 목적을 달성하기 위한 본 고안의 일례는 상부탱크와 하부탱크 사이에 열교환기가 배치되는 자동차용 라디에이터에 있어서, 열교환기의 튜브가 알루미늄 발포금속으로 이루어지며, 상기 튜브 둘레에 별도의 핀을 설치하지 않아도 되는 것을 특징으로 한다.One example of the present invention for achieving the above object is in an automobile radiator in which a heat exchanger is disposed between an upper tank and a lower tank, the tube of the heat exchanger is made of aluminum foam metal, and a separate fin around the tube It does not need to be installed.

상기 발포금속은 알루미늄발포체, 구리발포체, 알루미늄 구리 합금발포체이며, 요홈 및 공극이 형성되어 열교환 면적이 넓어 열교환기의 냉각수를 충분히 냉각시킬 수 있다.The foamed metal is an aluminum foam, a copper foam, an aluminum copper alloy foam, and grooves and voids are formed, so that the heat exchange area is wide, thereby sufficiently cooling the cooling water of the heat exchanger.

이하 첨부 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail.

12 : 열교환기 15 : 튜브12 heat exchanger 15 tube

17 : 알루미늄 박막 코팅층17: aluminum thin film coating layer

도 3을 참조하면, 본 고안에 따른 라디에이터는 상부탱크(11)와 하부탱크(13) 사이에 열교환기(12)가 배치되며, 열교환기(12)의 튜브(15)가 발포금속으로 이루어진다.3, in the radiator according to the present invention, a heat exchanger 12 is disposed between the upper tank 11 and the lower tank 13, and the tube 15 of the heat exchanger 12 is made of a foamed metal.

도 4에 도시된 바와같이 열교환기(12)의 튜브(15)는 내측 표면에 알루미늄 박막 코팅층(17)에 도포되어 튜브를 통과하는 유체가 발포금속에 형성된 공극(19)을 통해 누수되는 것을 방지한다.As shown in FIG. 4, the tube 15 of the heat exchanger 12 is applied to the aluminum thin film coating layer 17 on the inner surface to prevent the fluid passing through the tube from leaking through the pores 19 formed in the foamed metal. do.

상기 발포금속은 알루미늄발포체, 구리발포체, 알루미늄 구리 합금발포체이며, 알루미늄, 구리 등을 용해할 때 가스를 주입시키면 표면에 많은 요홈이 형성되어 그 내부에 많은 공극이 형성되어 상기 알루미늄발포체, 구리발포체, 알루미늄 구리 합금발포체가 형성된다. 이러한 발포금속은 열교환기의 튜브 둘에에 핀을 설치하지 않아도 될 정도로 열교환 면적이 넓어 열교환 효율이 크다.The foamed metal is an aluminum foam, a copper foam, an aluminum copper alloy foam, and when a gas is infused when dissolving aluminum, copper, many grooves are formed on the surface, and many voids are formed therein, so that the aluminum foam, copper foam, An aluminum copper alloy foam is formed. The foamed metal has a large heat exchange area such that the fins are not required to be installed at two tubes of the heat exchanger, thereby increasing heat exchange efficiency.

상기 알루미늄 구리 합금발포체는 알루미늄과 구리의 합금비율이 6:4∼9:1이 바람직하다.The aluminum copper alloy foam is preferably an alloy ratio of aluminum and copper of 6: 4 to 9: 1.

상기와 같이 구성된 본 고안의 자동차용 라디에이터는 열교환기(12)의 튜브(15)의 표면적이 크기 때문에 종래의 라디에이터의 열교환기 성능 만큼 충분히 열교환을 할 수 있어, 상기 튜브 둘레에 별도의 핀을 설치하지 않아도 된다.Since the radiator for automobiles of the present invention configured as described above has a large surface area of the tube 15 of the heat exchanger 12, the heat exchanger may sufficiently exchange heat as much as the performance of a heat exchanger of a conventional radiator, thus providing a separate fin around the tube. You do not have to do.

상기와 같은 본 고안에 따른 차동차용 라디에이터는 열교환 효율이 큰 발포금속을 이용하여 열교환기를 제조하므로서 열교환기의 튜브 둘레에 핀을 설치하지 않아도 되므로 제조하기 용이하고, 제작 비용이 절감되는 효과가 있다.The radiator for a differential vehicle according to the present invention as described above is easy to manufacture because it does not need to install a fin around the tube of the heat exchanger by manufacturing a heat exchanger using a foamed metal having a high heat exchange efficiency, and the manufacturing cost is reduced.
