본 발명은 전기발열소자를 사용하는 프리히터의 하우징에 대한 것으로, 속으로 조립되는 히트싱크의 발열플레이트부분을 일체로 구성하여 조립성을 향상시키고, 완벽한 수밀성을 가질 수 있도록 하는데 특징이 있는 것이다.The present invention relates to a housing of a preheater using an electric heating element, characterized in that the heat generating plate portion of the heat sink to be assembled into the body integrally to improve the assemblability, to have a perfect water tightness.

일반적으로 전기발열소자를 사용하는 프리히터는 자동차의 실내공기를 가열시키기 위한 보조 히터로서, 자동차 엔진의 냉각수가 미처 가열되지 않았을 때, 전기 에너지로 먼저 냉각수를 가열시켜 자동차의 실내를 난방시킬 수 있도록 하는데 사용한다.In general, the preheater using the electric heating element is an auxiliary heater for heating the indoor air of the vehicle. When the coolant of the automobile engine is not heated, the preheater first heats the coolant with electric energy to heat the interior of the vehicle. Used to

이때의 프리히터는 도 1에서 보는 바와 같이 본체부(11)와, 그 좌, 우 양쪽에서 일체로 연장된 냉각수 유입관(12)과, 냉각수 유출관(13), 상기 본체부(11)의 저면으로 형성된 개구부(14), 상기 본체부(11)의 상측에 부착된 브라켓트(15)로 하우징(10)이 이루어 지며, 상기 하우징(10)의 개구부(14)로 삽입되는 히트싱크 어셈브리(20)는 도 2에서 보듯이 표면 발열플레이트(21)와 이면 발열플레이트(22)로 구성하되, 이들 표면 발열플레이트(21)와 이면 발열플레이트(22)의 내면에는 각각 소자 안착부(24)가 형성되어 있어 전기 발열소자(30)를 내장할 수 있으며, 이들 발열소자(30)의 사이에는 전극단자(40)가 삽입되고, 또 상기한 표면 발열플레이트(21)와 이면 발열플레이트(22)의 사이에는 전기 발열소자가 내장된 부분을 제외하도록 관통부(50a)를 가진 실링부재(50)가 개입되어 있다.As shown in FIG. 1, the preheater includes the main body 11, the coolant inlet pipe 12 extending integrally from both the left and right sides thereof, the coolant outlet pipe 13, and the main body 11. The housing 10 is formed of an opening 14 formed in a bottom surface and a bracket 15 attached to an upper side of the main body 11, and a heat sink assembly inserted into the opening 14 of the housing 10. 20 is composed of a surface heating plate 21 and the rear heating plate 22, as shown in Figure 2, the element mounting portion 24 is respectively formed on the inner surface of the surface heating plate 21 and the rear heating plate 22; It is formed so that the electric heating element 30 can be incorporated, the electrode terminal 40 is inserted between the heating element 30, and the above-mentioned surface heating plate 21 and the rear heating plate 22 Between the sealing member 50 having a penetrating portion 50a so as to exclude a portion in which the electric heating element is embedded, The.

이와 같은 종래의 히트싱크 어셈브리(20)에 있어서 지적되는 문제점은 히트싱크 어셈브리를 엔진 냉각수가 통과하는 하우징의 내부로 삽입한 채 조립하는데 있어서, 수밀성과 조립성이 떨어진다는 점이다.A problem that is pointed out in the conventional heat sink assembly 20 is that the heat sink assembly is inferior in water tightness and assemblability in assembling the heat sink assembly into the housing through which the engine coolant passes.

즉, 히트싱크 어셈브리(20)는 그 내부에 전기 발열소자(30)를 내재 하여야 하기 때문에 표면 발열플레이트(21)와 이면 발열플레이트(22)를 맞대어 조립해야 하고, 따라서 이들의 틈새를 철저히 차단해야만 수밀성이 보장되지만 완벽한 수밀성을 기대하기는 어려운 것이다.That is, since the heat sink assembly 20 should have the electric heating element 30 therein, the heat sink assembly 20 must be assembled to face the heat generating plate 21 and the rear heat generating plate 22, thus completely blocking the gap thereof. Watertightness is guaranteed only, but it is difficult to expect perfect watertightness.

또한 히트싱크 어셈브리(20)를 하우징(10)의 저면에 형성된 개구부(14)를 통해 삽입한 후, 이를 고정할 때도 그 부분의 수밀성이 보장되어야 할 뿐만 아니라 수밀성이 보장되도록 조립하기 위한 조립구조가 복잡하였다.In addition, after inserting the heat sink assembly 20 through the opening 14 formed in the bottom surface of the housing 10, the assembly structure for assembling not only to ensure the watertightness of the part but also to ensure the watertightness when fixing it. Was complicated.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보안하고자 안출한 것으로서, 발명의 주된 목적은 하우징이 내부에 위치하게될 히트싱크 어셈브리의 플레이트를 상기 하우징과 일체로 형성하므로써 수밀성 문제를 해결하고, 또 조립까지 간편해지도록 하고자 하는데 있는 것이다.Therefore, the present invention has been made in view of the above-mentioned conventional problems to solve the security, the main object of the invention is to form a plate of the heat sink assembly in which the housing is to be located inside the water-tightness problem by forming integrally with the housing It is to solve and to simplify the assembly.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성은 본체부와, 그 좌, 우 양쪽에서 일체로 연장된 냉각수 유입관과, 냉각수 유출관, 상기 본체부의 저면으로 형성된 개구부, 상기 본체부의 상측에 부착된 브라켓트로 형성하여 상기 하우징의 내부에 히트싱크 어셈브리를 내장할 수 있도록 된 전기발열소자를 사용하는 프리히터에 있어서, 상기한 하우징은 하측 개구부를 밀폐하도록 일체로 형성한 평판부와,상기 평판부로부터 본체부 속으로 일체가 되도록 연장하되, 다수의 전기발열소자용 내장부를 구비한 히트싱크 플레이트부로 형성하고, 상기의 내장부 속으로 삽입할 전기발열소자 셋트는 전기발열소자와, 전기발열소자에 접하는 전극단자와, 상기 전극단자의 끝단을 결속하기 위한 결속부재로 구성하는데 있다.A characteristic configuration of the present invention for achieving the above object is a main body portion, the cooling water inlet tube extending integrally from both left and right, the cooling water outlet tube, the opening formed by the bottom surface of the body portion, attached to the upper side of the body portion A preheater using an electric heating element formed of a bracket to be able to embed a heat sink assembly in the housing, wherein the housing is integrally formed to seal the lower opening, and the plate Extending from the unit into the main body unit, the heat sink plate having a plurality of built-in parts for electric heating elements, wherein the set of electric heat generating elements to be inserted into the built-in parts includes an electric heat generating element and an electric heating element And a binding member for binding the electrode terminal in contact with the end of the electrode terminal.

이하 본 발명의 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 프리히터는 새로운 하우징(60)과, 새로운 전기발열소자 셋트(70)로 이루어 진다.The preheater of the present invention consists of a new housing 60 and a new set of electric heating elements 70.

상기 하우징(60)은 본체부(61)와, 그 좌, 우 양쪽에서 일체로 연장된 냉각수 유입관(62)과, 냉각수 유출관(63), 그리고 상기 본체부(61)의 상측에 부착된 브라켓크(65)로 형성하되, 하측을 밀폐한 평판부(66)와, 상기 평판부로부터 본체부 속으로 연장되면서 그 내부에 다수의 전기발열소자용 내장부(67)가 구비되고, 이 내장부(67)는 하측으로 개방되어 있는 히트싱크 플레이트부(68)로 이루어 진다.The housing 60 is attached to the main body portion 61, the coolant inlet pipe 62 integrally extending from both left and right sides thereof, the coolant outlet pipe 63, and an upper side of the main body portion 61. It is formed of a bracket (65), the lower side is sealed plate portion 66, and extending from the plate portion into the main body portion is provided with a plurality of built-in portion 67 for the electric heating element therein, the interior The portion 67 is composed of a heat sink plate portion 68 which is open downward.

또 한, 상기의 전기발열소자 셋트(70)는 도 상기 내장부(67) 속으로 삽입할 전기발열소자(71)와, 전기발열소자에 접하는 전극단자(72)와, 상기 전극단자의 끝단(72a)을 결속하기 위한 결속부재(73)로 이루어진 것이다.In addition, the electric heating element set 70 is an electric heating element 71 to be inserted into the interior portion 67, an electrode terminal 72 in contact with the electric heating element, and the end of the electrode terminal ( It is made of a binding member 73 for binding 72a).

본 발명의 프리히터를 조립하고자 할 때는 먼저, 전기발열소자 셋트(70)를 조립한다. 즉, 전기발열소자(71)의 표면에 전극단자(72)가 접하도록 하고, 이 상태에서 상기한 전기발열소자(71)를 히트싱크 플레이트부(68)의 내장부(67) 속으로 끼워지도록 하고, 각각의 내장부(67)에 모두 전기발열소자(71)가 삽입된 후에는 상기의 전극단자의 끝단(72a)과 결속부재(73)를 포함하여 커버(80)를 씌운다.When assembling the preheater of the present invention, first, the electric heating element set 70 is assembled. That is, the electrode terminal 72 is brought into contact with the surface of the electric heat generating element 71, and in this state, the electric heat generating element 71 is inserted into the interior portion 67 of the heat sink plate portion 68. After the electric heating element 71 is inserted into each of the internal parts 67, the cover 80 is covered with the end 72a of the electrode terminal and the binding member 73.

위에서 상세히 설명한 바와 같은 본 발명은 하우징의 내부에 히트싱크 플레이트부를 일체로 형성하고, 그 내부에 전기발열소자 셋트를 삽입할 수 있도록 하였기 때문에 상기한 하우징의 내부를 흐르는 냉각수는 히트싱크 플레이트부 속의 전기발열소자 셋트로 전혀 침투될 수 없게 되는 장점이 있다.Since the present invention as described in detail above allows the heat sink plate portion to be integrally formed inside the housing, and an electric heat generating element set can be inserted therein, the coolant flowing in the inside of the housing is applied to the electric heat in the heat sink plate portion. There is an advantage that can not be penetrated into the heating element set at all.

뿐만 아니라 종래와 달리 히트싱크 어셈브리를 조립한 후, 하우징에 조립하는 것이 아니라 전기발열소자 셋트를 직접 하우징 속의 히트싱크 플레이트부에 조립하면 되기 때문에 조립이 간편해지는 장점도 있는 것이다.In addition, unlike the prior art, after assembling the heat sink assembly, rather than assembling in the housing, there is an advantage that the assembly is easy because the electric heat generating element set directly into the heat sink plate portion in the housing.
