Abstract
A protective cover 7 is disposed on an airflow upstream side of a tube 2. Even when relatively large flying materials such as gravel impinge against a radiator 1, the flying materials are prevented from directly striking the tubes 2. As the tube 2 can thus be protected from the relatively large flying materials such as gravel, the radiator 1 can continue operating, and the reliability of the radiator 1 can be improved.
Claims6
A heat exchanger comprising:
- a plurality of tubes arranged in parallel with one another, and allowing a fluid to flow therethrough;
- header tanks arranged at end portions of said tubes in a longitudinal direction, and communicating with said plurality of tubes;
- and
- tube protective members for protecting said tubes, disposed on an airflow upstream side of said tubes, and being separate members from said tubes.
1 more element
A heat exchanger comprising:
- a plurality of tubes through which a fluid flows;
- and
- fins each bonded to an outer surface of each of said tubes, for increasing a heat transfer area with air;
- wherein said fin extends to at least a front side of said tube and encompasses the front side of said tube.
1 more element
A heat exchanger comprising:
- a plurality of tubes through which a fluid flows;
- and
- fins each bonded to an outer surface of each of said tubes, for increasing a heat transfer area with air;
- wherein said tube is shaped into a compressed flat shape so that an airflow direction coincides with a major diameter direction, and said fin is bonded to said compressed flat surface in such a fashion as to cover substantially the whole area of said compressed flat surface of an outer surface of said tube.
1 more element
A heat exchanger comprising:
- a plurality of tubes arranged in parallel with one another, and allowing a fluid to flow therethrough;
- header tanks arranged at end portions of said tubes in a longitudinal direction, and communicating with said plurality of tubes;
- and
- fins each brazed to an outer surface of each of said tubes, for promoting heat exchange between said fluid and air;
- wherein a tube protective portion is formed by a filler metal on an airflow upstream side of said tube when said filler metal is solidified in a brazing process of said tube and said fin.
