1. A heat exchanger comprising a cylindrical steel jacket and two hemispherical head pieces, with a first distribution chamber, which is connected with a second distribution chamber by means of tubes for the passage of a hot medium, at least some of the tubes extending through an inlet region of a cooling medium and through an outer chamber, wherein lateral ports introduce the cooling medium into an inlet region which is adjoined by an inner chamber defined by a sealing plate for flow deflection of the cooling medium, that the sealing plate guides the cooling medium from the inner chamber into an outer chamber, the outer chamber enclosing the inner chamber, and this outer chamber is provided with ports for discharging the cooling medium.
2. The heat exchanger as claimed in claim 1, wherein a separation of the inner chamber from the outer chamber is effected by a heat-insulating wall.
3. The heat exchanger as claimed in claim 1, wherein in the outer chamber the flow of the cooling medium is deflected by sheets.
4. The heat exchanger as claimed in claim 1, wherein the inlet region is insulated against the first distribution chamber by a heat-insulating mass.
5. The heat exchanger as claimed in claim 4, wherein the heat-insulating mass is catalytically active.
6. The heat exchanger as claimed in claim 4, wherein in the vicinity of the heat-insulating mass spigots are mounted, which receive at least some of the tubes.
7. The heat exchanger as claimed in claim 1, wherein the heat exchanger is fabricated in a floating head design.
8. The heat exchanger as claimed in claim 1, wherein an outlet port of the heat exchanger has a compensator.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A weatherstrip comprising:
an elongated elastomeric member having a core received therein for securing the elastomeric member to an associated vehicle flange;
a lip defined along a portion of the elastomeric member for receipt in an associated vehicle interior; and
one of a cloth and flock layer disposed on the lip.
2. The weatherstrip of claim 1 further comprising a thermoplastic layer securing the one layer on the lip.
3. The weatherstrip of claim 2 wherein the thermoplastic layer is of sufficient thickness to form a color barrier between the elastomeric member and the one layer.
4. The weatherstrip of claim 1 wherein the core includes longitudinally spaced breaks for permitting the weatherstrip to be more easily bent along the breaks.
5. The weatherstrip of claim 1 wherein the one layer color coordinates with the associated vehicle interior.
6. The weatherstrip of claim 1 further comprising a seal bulb extending from the elastomeric member.
7. The weatherstrip of claim 6 wherein the seal bulb is hollow.
8. The weatherstrip of claim 1 wherein the core is generally U-shaped, and the elastomeric member includes at least one retaining finger adjacent the core for gripping the associated vehicle flange.
9. The weatherstrip of claim 1 wherein a portion of the elastomeric member forms a flange attachment.
10. A method of forming a weatherstrip comprising:
providing an elastomeric body having a lip;
forming a flange attachment mechanism on the body;
applying a first layer of plastic on the lip; and
securing one of a flock and cloth decorative layer on the first layer.
11. The method of claim 10 wherein the elastomeric body providing step includes the step of extruding the body.
12. The method of claim 11 wherein the elastomeric body providing step includes incorporating a core in the body.
13. The method of claim 12 further comprising breaking the core at longitudinally spaced locations.
14. The method of claim 13 wherein the securing step is completed after the core breaking step.
15. The method of claim 14 wherein the applying step is completed after the core breaking step.
16. The method of claim 10 wherein the first layer is of sufficient thickness to form a barrier layer so that the elastomeric body cannot be seen through the decorative layer.
17. The method of claim 10 forming step includes applying the elastomeric body over a generally U-shaped core.
18. The method of claim 10 further comprising including a seal bulb on the body.
19. The method of claim 10 wherein the elastomeric body providing step includes incorporating a core in the body, breaking the core at longitudinally spaced locations, and then inserting the elastomeric body through an extrusion die to apply the first layer.
20. The method of claim 19 wherein the decorative layer securing step includes introducing the decorative layer on to the first layer at the extrusion die.
