Abstract
A heat exchanger is disclosed. The heat exchanger includes a protective device, mutually parallel tubes through which a first fluid circulates, and perpendicular fins connecting two successive flat tubes, a second fluid circulating between said flat tubes by passing through said fins, the protective device being apertured so as to allow the circulation of the second fluid through the fins. The protective device includes fixing spikes which are inserted forcibly between the fins.
Claims5
A heat exchanger, for a motor vehicle, comprising:
- a protective device;
- mutually parallel tubes through which a first fluid circulates;
- and
- perpendicular fins connecting two successive tubes, a second fluid circulating between said tubes by passing through said fins,
- said protective device being apertured into longitudinal bars covering sides of the tubes and separated by parallel slots, wherein each of the parallel slots is divided into a sequence of apertures by spacers connecting said longitudinal bars so as to allow the circulation of the second fluid through the fins,
- wherein said protective device comprises fixing spikes integrally molded on said spacers to have a length of each fixing spike greater than or equal to a width of the fins, said fixing spikes are inserted forcibly between the fins,
- wherein said fixing spikes are disposed away from a periphery of the heat exchanger.
