Abstract

특히 차량용 엔진 냉각 라디에이터 및/또는 차실내 공기의 난방 라디에이터로 사용되는 열교환기는 구멍(26)이 형성되어 있는 헤더판(10)을 갖는다. 각 구멍은 라디에이터 관다발의 상이한 관세트에서 복수의 인접한 각 관말 단부를 수납한다. 밀봉가스켓은 상기 헤더판과 상기 관사이에 개재된다. 상기 관말단부(58)와 상기 대응구멍(26)은 그 사이에서 거의 일정한 폭(e₁)의 환상갭(60)을 형성하는 쌍결합 형태의 단면을 갖고, 이 환상갭은 거의 일정한 폭(e₂)을 갖는 공통 영역(62)에 의해서 각 구멍(26)에 연결된다.In particular, a heat exchanger used as a vehicle engine cooling radiator and / or a heating radiator for in-vehicle air has a header plate 10 in which holes 26 are formed. Each hole receives a plurality of adjacent end ends of each tube set of radiator tubes. The sealing gasket is interposed between the header plate and the tube. The tube end portion 58 and the corresponding hole 26 have a cross-section in the form of a twin coupling forming an annular gap 60 having a substantially constant width e ₁ therebetween, and the annular gap has a substantially constant width e. _It is connected to each hole 26 by a common area 62 having ₂ ).

Claims

A heat exchanger of the type comprising parallel tube bundles arranged in sets, with header plates formed with a plurality of holes, wherein a different tube of tube bundles is provided with a compressible sealing gasket interposed between the edge of the hole and the tube end. the tube end portion 58 and the hole 26 is a substantially constant width of the respective gap to accommodate this, each having the hole, and the tube 54 for housing the respective ends of the plurality of adjacent pipe of the set (e ₁ Width of the common region (e ₂ ) having a pair-shaped cross section defining an annular gap 60 between the tube end and the hole, wherein the annular gap 60 of each of the holes 26 is substantially constant. Heat exchanger, characterized in that they are connected to each other in a common area (62) between two adjacent tube ends (58).

2. Heat exchanger according to claim 1, characterized in that the two adjacent tube ends (58) have a substantially flat surface (64) extending parallel to each other.

3. The heat exchanger according to claim 2, wherein each said substantially flat surface is formed by local deformation of the corresponding tube end (58).

The tube end portion 58 according to claim 2 or 3, wherein the tube end portion 58 has an approximately oval or elliptical cross-sectional shape that forms a major axis XX 'and a minor axis YY', and is substantially flat. Heat exchanger, characterized in that the surface (64) is arranged at one end of the long axis (XX ').

5. The heat exchanger as claimed in claim 1, wherein the width e ₂ of the common region is approximately equal to twice the width of the annular gap. 6.

The compression gasket (34) according to any one of the preceding claims is adapted to fit into the annular portion (44) having a substantially constant thickness and the common area (62) before being adapted and pressed to fit the annular gap (60). And a common portion (46) having a substantially constant thickness before being adapted and compressed.
