본 발명은 열교환기에 관한 것으로서, 더욱 상세하게는 헤더탱크에 결합되는 엔드캡 또는 입구파이프에 열교환매체를 일부 가로막는 돌출수단을 형성하여 입구파이프를 통해 유입되는 열교환매체가 먼곳의 튜브에까지 균일하게 흐를 수 있도록 함으로서 각각의 튜브로 균일한 양의 열교환매체가 공급되어 열교환기의 표면 온도를 균일하게 유지함과 동시에 열교환기를 통과한 공기의 온도편차를 줄일 수 있는 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, an end cap or inlet pipe coupled to a header tank forms a protruding means for partially blocking the heat exchange medium so that the heat exchange medium flowing through the inlet pipe can flow uniformly to a distant tube. The present invention relates to a heat exchanger capable of supplying a uniform amount of heat exchange medium to each tube to maintain a uniform surface temperature of the heat exchanger and at the same time reduce the temperature deviation of the air passing through the heat exchanger.

자동차 공조장치에 사용되는 열교환기는 냉,난방시스템의 열교환매체 유로상에 설치되어 그 내부를 흐르는 열교환매체가 외기열을 흡열하도록 하거나 또는 자신의 열을 외부로 방열하는 방식으로 열교환을 수행하도록 하여 소정공간을 냉,난방할 수 있게 한다.The heat exchanger used in the automotive air conditioner is installed on the heat exchange medium flow path of the cooling and heating system so that the heat exchange medium flowing therein absorbs outside heat or radiates its own heat to the outside. Allow the room to cool and heat.

상기한 열교환기로는 증발기, 히터코어, 응축기, 라디에이터 등을 들수 있으며, 송풍기에 의하여 송풍되는 공기를 열교환시켜 차실내를 냉,난방하는 공조케이스에는 이들 중 증발기와 히터코어가 선택적으로 설치된다.Examples of the heat exchanger include an evaporator, a heater core, a condenser, and a radiator. Among the heat exchangers, an evaporator and a heater core are selectively installed in an air conditioning case that heats and heats the air blown by the blower.

도 1 은 이러한 열교환기(1) 중에서 히터코어를 일예로 도시한 것이며, 이를 설명하면, 상하로 일정간격 이격되어 상호 나란하게 배열되는 상,하부 헤더탱크(2)(3)와, 상기 상,하부 헤더탱크(2)(3)의 양단부에 결합되는 엔드캡(9)과, 상기 상,하부 헤더탱크(2)(3)에 그 양단부가 결합되는 다수의 튜브(4)와, 상기 튜브(4)들 사이에 각각 개재되는 방열핀(5)과, 상기 상,하부 헤더탱크(2)(3)의 엔드캡(9) 에 결합되어 열교환매체를 유입하는 입,출구파이프(7)(8)로 이루어진다.1 illustrates an example of a heater core in the heat exchanger 1, and when it is described, upper and lower header tanks 2 and 3 arranged side by side at a predetermined interval up and down, and the upper, End caps 9 coupled to both ends of the lower header tanks 2 and 3; a plurality of tubes 4 coupled to both upper and lower header tanks 2 and 3; 4) inlet and outlet pipes 7 and 8 which are coupled to the heat dissipation fins 5 interposed between the upper and lower header tanks 2 and 3 and to the end caps 9 of the upper and lower header tanks 2 and 3. Is made of.

그리고, 상기 튜브(4)들과 방열핀(5)들을 보강하기 위해 이들의 최외곽에는 사이드 서포트(6)가 구비된다.And, in order to reinforce the tubes 4 and the heat dissipation fins 5, side supports 6 are provided at their outermost sides.

따라서, 열교환매체는 상기 입구파이프(7)를 통해 상기 하부 헤더탱크(3)의 내부로 유입되고, 이후 상기 튜브(4)들을 따라 흐르면서 상기 상부 헤더탱크(2)의 내부로 유입된다.Therefore, the heat exchange medium flows into the lower header tank 3 through the inlet pipe 7 and then flows through the tubes 4 into the upper header tank 2.

계속해서, 상기 상부 헤더탱크(2)로 유입된 열교환매체는 상기 출구파이프(8)를 통해 배출되는 것이다.Subsequently, the heat exchange medium introduced into the upper header tank 2 is discharged through the outlet pipe 8.

여기서, 상기 열교환매체는 상기 튜브(4)들을 통과하면서 방열핀(5)에 열을 전달하여 외부공기와 활발한 열교환을 수행하게 된다.Here, the heat exchange medium transfers heat to the heat radiating fins 5 while passing through the tubes 4 to actively perform heat exchange with external air.

그러나, 상기한 종래의 열교환기(1)는 상기 각 튜브(4)로 흐르는 열교환매체량이 불균일하여 열교환기(1) 표면의 온도도 불균일한 문제가 있었다.However, the conventional heat exchanger 1 has a problem that the temperature of the surface of the heat exchanger 1 is also uneven because the amount of heat exchange medium flowing through the respective tubes 4 is uneven.

즉, 상기 입구파이프(7)를 통해 하부 헤더탱크(3)로 유입된 열교환매체가 상기 전체 튜브(4)들로 균일하게 흘러가야 하지만, 그렇지 못하고 상기 입구파이프(7)와 가까운 튜브(4)들측으로 대부분 흘러가게 되면서 입구파이프(7)와 먼곳에 위치한 튜브(4)들로는 적은 양의 열교환매체가 흘러가게 된다.That is, although the heat exchange medium flowing into the lower header tank 3 through the inlet pipe 7 should flow uniformly to the entire tubes 4, the tube 4 close to the inlet pipe 7 is not. Most of the flow to the field side is a small amount of heat exchange medium flows to the inlet pipe (7) and the tube (4) located far away.

따라서, 열교환기(1)의 표면 온도가 불균일하게 되고, 이에 따라 열교환기(1)를 통과한 공기의 온도편차도 크게 발생하는 등의 문제가 있었다.Therefore, the surface temperature of the heat exchanger 1 becomes nonuniform, and there existed a problem that the temperature deviation of the air which passed through the heat exchanger 1 also generate | occur | produces large.

상기한 종래의 문제점을 해결하기 위한 본 발명의 목적은 헤더탱크에 결합되 는 엔드캡 또는 입구파이프에 열교환매체를 일부 가로막는 돌출수단을 형성하여 입구파이프를 통해 유입되는 열교환매체가 먼곳의 튜브에까지 균일하게 흐를 수 있도록 함으로서 각각의 튜브로 균일한 양의 열교환매체가 공급되어 열교환기의 표면 온도를 균일하게 유지함과 동시에 열교환기를 통과한 공기의 온도편차를 줄일 수 있는 열교환기를 제공하는데 있다.An object of the present invention for solving the above-mentioned problems is to form a protruding means for partially blocking the heat exchange medium in the end cap or the inlet pipe coupled to the header tank, so that the heat exchange medium flowing through the inlet pipe is uniform to the distant tube. It is possible to provide a heat exchanger that can supply a uniform amount of heat exchange medium to each tube to maintain a uniform surface temperature of the heat exchanger and to reduce the temperature deviation of the air passing through the heat exchanger.

상기의 목적을 달성하기 위해 본 발명은 상호 나란하게 일정간격 이격되고 내부에 통로가 형성된 상,하부 헤더탱크와, 상기 상,하부 헤더탱크의 양단부에 결합되는 엔드캡과, 상기 상,하부 헤더탱크에 그 양단부가 결합되는 다수의 튜브와, 상기 튜브들 사이에 개재되는 방열핀과, 상기 상,하부 헤더탱크의 엔드캡에 결합되는 입,출구 파이프를 포함하여 이루어진 열교환기에 있어서, 상기 엔드캡과 입구파이프 중 어느 한 곳에는 입구파이프를 통해 유입된 열교환매체가 먼곳의 튜브에까지 균일하게 흐를 수 있도록 유입되는 열교환매체를 일부 가로막는 돌출수단이 구비되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides an upper cap and a lower header tank spaced apart from each other by a predetermined interval in parallel with each other, an end cap coupled to both ends of the upper and lower header tanks, and the upper and lower header tanks. A heat exchanger comprising a plurality of tubes coupled to both ends thereof, a heat dissipation fin interposed between the tubes, and an inlet and an outlet pipe coupled to end caps of the upper and lower header tanks. Any one of the pipes is characterized in that the heat exchange medium introduced through the inlet pipe is provided with a protrusion means for partially blocking the heat exchange medium flows in such a way that it evenly flows to the far tube.

이하, 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

종래에 있어서와 동일한 구성 및 작용에 대한 반복되는 설명은 생략한다.Repeated description of the same construction and operation as in the prior art will be omitted.

도 2 는 본 발명에 따른 열교환기를 나타내는 사시도이고, 도 3 은 본 발명에 따른 열교환기에서 입구파이프에 돌출수단이 형성된 상태를 나타내는 단면도이며, 도 4 는 본 발명에 따른 열교환기에서 엔드캡에 돌출수단이 형성된 상태를 나타내는 단면도이다. Figure 2 is a perspective view showing a heat exchanger according to the present invention, Figure 3 is a cross-sectional view showing a state in which a protruding means is formed in the inlet pipe in the heat exchanger according to the present invention, Figure 4 is a protruding end cap in the heat exchanger according to the present invention It is sectional drawing which shows the state in which the means was formed.                     

본 발명에 따른 열교환기(100)는 상하로 일정간격 이격되어 상호 나란하게 배열되고 내부에는 열교환매체가 유동할 수 있도록 통로가 형성된 상,하부 헤더탱크(110)(120)와, 상기 상,하부 헤더탱크(110)(120)의 양단부에 결합되는 엔드캡(170)과, 상기 상,하부 헤더탱크(110)(120)에 그 양단부가 결합되어 상,하부 헤더탱크(110)(120)를 연통시키는 다수의 튜브(130)와, 상기 튜브(130)들 사이에 개재되어 전열면적을 넓혀 열교환을 촉진시키는 방열핀(140)과, 상기 튜브(130) 및 방열핀(140)을 보호하기 위해 이들의 최외곽에 설치되는 사이드 서포트(150)로 구성된다.The heat exchanger 100 according to the present invention is spaced up and down at a predetermined interval and arranged in parallel with each other, the upper and lower header tanks 110 and 120 formed with a passage to allow the heat exchange medium to flow therein, and the upper and lower parts. End caps 170 coupled to both ends of the header tanks 110 and 120 and both ends of the upper and lower header tanks 110 and 120 are coupled to the upper and lower header tanks 110 and 120. A plurality of tubes 130 communicating with each other, a heat dissipation fin 140 interposed between the tubes 130 to widen the heat transfer area to promote heat exchange, and to protect the tubes 130 and the heat dissipation fin 140. It is composed of a side support 150 installed in the outermost.

여기서, 상기 상,하부 헤더탱크(110)(120)는 튜브(130)들의 양단이 결합될 수 있도록 다수의 튜브홀(미도시)이 형성된 헤더(111)(121)와, 상기 헤더(111)(121)와 결합되어 열교환매체가 유동할 수 있는 통로를 형성하는 탱크(112)(122)가 결합하여 이루어진다.Here, the upper and lower header tanks 110 and 120 are headers 111 and 121 in which a plurality of tube holes (not shown) are formed so that both ends of the tubes 130 may be coupled, and the header 111. The tanks 112 and 122 are combined to form a passage through which the heat exchange medium may flow.

또한, 상기 상,하부 헤더탱크(110)(120)의 소정의 위치에는 열교환매체를 각각 유입하고 배출할 수 있도록 입,출구 파이프(160)(161)가 형성된다.In addition, inlet and outlet pipes 160 and 161 are formed at predetermined positions of the upper and lower header tanks 110 and 120 so as to introduce and discharge heat exchange media, respectively.

즉, 상기 하부 헤더탱크(120)의 일단부에 결합된 엔드캡(170)에는 입구파이프(160)가 수평으로 결합되고, 상부 헤더탱크(110)의 일단부에 결합된 엔드캡(170)에는 출구파이프(161)가 수평으로 결합된다.That is, the inlet pipe 160 is horizontally coupled to the end cap 170 coupled to one end of the lower header tank 120, and the end cap 170 coupled to one end of the upper header tank 110. The outlet pipe 161 is horizontally coupled.

따라서, 상기 입,출구파이프(160)(161)가 결합되는 엔드캡(170)에는 각 입,출구파이프(160)(161)와 연통할 수 있도록 연통공(171)이 형성되어 있다.Accordingly, the end cap 170 to which the inlet and outlet pipes 160 and 161 are coupled is formed with a communication hole 171 to communicate with each inlet and outlet pipe 160 and 161.

한편, 상기 입구파이프(160)는 상기 상부 헤더탱크(110)측에 결합될 수 있 고, 출구파이프(161)는 하부 헤더탱크(120)측에 결합될 수 도 있다.On the other hand, the inlet pipe 160 may be coupled to the upper header tank 110 side, the outlet pipe 161 may be coupled to the lower header tank 120 side.

이러한, 상기 각 구성요소들은 가조립된 상태에서 브레이징 의해 상호 접합되는 것이다.Each of these components is joined together by brazing in a preassembled state.

그리고, 엔드캡(170)과 입구파이프(160) 중 어느 한 곳에는 입구파이프(160)를 통해 유입된 열교환매체가 먼곳의 튜브(130)에까지 균일하게 흐를 수 있도록 유입되는 열교환매체를 일부 가로막는 돌출수단(165)이 구비된다.In addition, any one of the end cap 170 and the inlet pipe 160 protrudes to partially block the heat exchange medium introduced so that the heat exchange medium introduced through the inlet pipe 160 flows uniformly to the tube 130 in the distance. Means 165 are provided.

여기서, 상기 돌출수단(165)을 상기 입구파이프(160)에 형성할 경우에는 상기 입구파이프(160)의 끝단부에 돌기부(160a)를 형성하되 상기 튜브(130)의 삽입측 방향에 형성하여 이루어진다.In the case where the protruding means 165 is formed in the inlet pipe 160, a protrusion 160a is formed at an end of the inlet pipe 160, but is formed in the insertion side of the tube 130. .

또한, 상기 돌출수단(165)을 상기 엔드캡(170)에 형성할 경우에는 상기 엔드캡(170)의 연통공(171)에 돌출부(172)를 형성하되 상기 튜브(130)의 삽입측 방향에 형성하여 이루어진다.In addition, when the protruding means 165 is formed in the end cap 170, the protruding portion 172 is formed in the communication hole 171 of the end cap 170, but in the insertion side direction of the tube 130. Formed.

즉, 도면에서와 같이 상기 입구파이프(160)가 하부 헤더탱크(120)측에 결합된 경우에는 상기 돌출수단(165)은 입구파이프(160)의 끝단부 상측에 형성되거나 엔드캡(170)의 연통공(171) 상측에 형성된다.That is, as shown in the drawing, when the inlet pipe 160 is coupled to the lower header tank 120 side, the protruding means 165 is formed above the end of the inlet pipe 160 or the end cap 170. The communication hole 171 is formed above.

따라서, 상기 돌출수단(165)이 상기 입구파이프(160)와 가까운 곳에 설치된 튜브(130)쪽으로 곧바로 유입되는 열교환매체를 차단하기 때문에 상기 입구파이프(160)로 공급되어지는 열교환매체는 입구파이프(160)와 가까운 곳에 설치된 튜브(130)들쪽으로 곧바로 흘러가지 않고 하부 헤더탱크(120)를 따라 흐르면서 입구파이프(160)로부터 먼 곳에 설치된 튜브(130)들에까지 충분한 양이 도달하여 각 튜브 (130)들로 균일하게 유입되는 것이다.Therefore, since the protruding means 165 blocks the heat exchange medium flowing straight toward the tube 130 installed near the inlet pipe 160, the heat exchange medium supplied to the inlet pipe 160 is the inlet pipe 160. In order to flow along the lower header tank 120 without directly flowing toward the tubes 130 installed close to each other, a sufficient amount reaches each tube 130 installed far from the inlet pipe 160. It will flow into the uniformly.

또한, 상기 입구파이프(160)를 통해 유입되는 열교환매체를 상기 돌출수단(165)이 일부 가로막음으로서 이 부위에서 유속이 빨라지게 되어 입구파이프(160)로부터 먼 곳에 설치된 튜브(130)들에까지 열교환매체가 도달할 수 있도록 도와주게 된다.In addition, as the protrusion means 165 partially blocks the heat exchange medium flowing through the inlet pipe 160, the flow velocity is increased at this portion, thereby exchanging heat to the tubes 130 installed far from the inlet pipe 160.

한편, 상기 엔드캡(170)의 연통공(171)에 돌출부(172)를 형성할 경우, 기존에 상기 입구파이프에 형성되었던 오비드(O-bead)를 생략할 수 있어서 그 만큼 공간절약을 할 수 있게 된다.On the other hand, when forming the protrusion 172 in the communication hole 171 of the end cap 170, it is possible to omit the O-bead that was previously formed in the inlet pipe can be space-saving as much Will be.

즉, 종래에는 상기 입구파이프(7:종래)의 단부측에 오비드(O-bead)를 형성하여 상기 엔드캡(9:종래)에 결합시 엔드캡(9:종래)측으로 삽입되는 길이를 제한할 수 있도록 하였지만, 본 발명에서는 상기 엔드캡(170)의 연통공(171)에 형성된 돌출부(172)가 입구파이프(160)의 삽입길이까지 제한할 수 있기 때문에 입구파이프(160)에 형성되던 오비드(O-bead)를 생략할 수 있으며, 이에따라 공간절약은 물론 오비드(O-bead)를 형성하기 위한 추가공정도 생략할 수 있어서 공정도 단축된다.
That is, in the related art, an O-bead is formed on an end side of the inlet pipe 7 (conventional) to limit the length of the end cap (9: conventional) inserted into the end cap (conventional). In the present invention, since the protrusion 172 formed in the communication hole 171 of the end cap 170 can be limited to the insertion length of the inlet pipe 160, the inlet formed in the inlet pipe 160 ( O-bead may be omitted, and accordingly, an additional process for forming an O-bead may be omitted as well as space saving.

상기한 바와 같이, 본 발명의 열교환기(100)에 따르면, 상기 입구파이프(160)를 통해 유입되는 열교환매체는 상기 하부 헤더탱크(120) 내로 유입된다.As described above, according to the heat exchanger 100 of the present invention, the heat exchange medium flowing through the inlet pipe 160 flows into the lower header tank 120.

이때, 상기 입구파이프(160) 또는 엔드캡(170)에 형성된 돌기부(160a) 또는 돌출부(172)가 상기 입구파이프(160)와 가까운 곳에 설치된 튜브(130)들로 곧바로 흘러갈려고 하는 열교환매체를 차단하기 때문에 상기 입구파이프(160)를 통해 유입 되는 열교환매체는 상기 입구파이프(160)로부터 먼 곳에 설치된 튜브(130)들에까지 충분한 양이 도달하게 된다.At this time, the inlet pipe 160 or the projections 160a or the protrusions 172 formed on the end cap 170 block the heat exchange medium that is about to flow directly to the tubes 130 installed near the inlet pipe 160. Therefore, the heat exchange medium flowing through the inlet pipe 160 reaches a sufficient amount to the tubes 130 installed far from the inlet pipe 160.

계속해서, 상기 열교환매체는 상기 전체 튜브(130)들로 균일한 양이 유입되어 흐르게 되고 이 과정에서 외부공기와 활발한 열교환을 수행한 후 상기 상부 헤더탱크(110)의 내부로 유입된다.Subsequently, the heat exchange medium flows into the entire tube 130 in a uniform amount and flows into the upper header tank 110 after active heat exchange with external air.

상기 상부 헤더탱크(110)의 내부로 유입된 열교환매체는 상기 출구파이프(161)를 통해 최종 배출되는 것이다.The heat exchange medium introduced into the upper header tank 110 is finally discharged through the outlet pipe 161.

이상에서 살펴본 바와 같이, 본 발명에서는 상기 엔드캡(170) 또는 입구파이프(160)에 열교환매체를 일부 가로막는 돌출수단(165)을 형성하여 열교환매체가 입구파이프(160)로부터 먼 곳에 설치된 튜브(130)에까지 균일하게 흐를 수 있도록 한 구성을 히터코어에 적용한 경우에 대해서만 설명하였지만, 여기에 한정되지 않고 라디에이터, 응축기, 증발기 등 모든 열교환기에 적용할 수 있으며, 동일한 효과를 얻을 수 있다.As described above, in the present invention, the tube 130 is formed in the end cap 170 or the inlet pipe 160 to form a protruding means 165 for partially blocking the heat exchange medium so that the heat exchange medium is located far from the inlet pipe 160. Although only a case of applying the configuration to the heater core to uniformly flow up to) has been described, the present invention is not limited thereto and can be applied to all heat exchangers such as radiators, condensers, and evaporators, and the same effect can be obtained.

상기한 본 발명에 따르면, 상기 엔드캡 또는 입구파이프에 돌출수단을 형성하여 입구파이프와 가까운 곳에 설치된 튜브들로 곧바로 흘러가는 유량을 차단하여 상기 입구파이프를 통해 유입되는 열교환매체가 먼곳의 튜브에까지 균일하게 흐를 수 있도록 함으로서 각각의 튜브로 균일한 양의 열교환매체가 공급되어 열교환기의 표면 온도가 균일하게 유지됨과 동시에 열교환기를 통과한 공기의 온도편차를 줄일 수 있다. According to the present invention, by forming a protruding means in the end cap or the inlet pipe to block the flow rate flowing straight to the tube installed in close proximity to the inlet pipe, the heat exchange medium flowing through the inlet pipe uniformly to the far-away tube By making it flow smoothly, a uniform amount of heat exchange medium is supplied to each tube, thereby maintaining a uniform surface temperature of the heat exchanger and reducing a temperature deviation of air passing through the heat exchanger.                     

또한, 상기 엔드캡의 연통공에 돌출부를 형성할 경우 상기 입구파이프에 형성되었던 오비드(O-bead)를 생략할 수 있게 됨으로서 그 만큼 공간절약을 할 수 있고 오비드(O-bead)를 형성하기 위한 추가공정도 생략되어 공정이 단축된다.
In addition, when forming a protrusion in the communication hole of the end cap it is possible to omit the (O-bead) formed in the inlet pipe, it is possible to save space as much as possible to form an O-bead (O-bead) Additional steps are also omitted, which shortens the process.
