Abstract
The application relates to a heat exchanger having a block with ribs and rectangular tubes. The block is arranged between a first collecting box and a second collecting box. Each collecting box is closed off by a base which has eyelets for receiving the tubes, and a trough-shaped circulating section for receiving the collecting box extends along the edge of the base. The base has an elevated contact region on at least one end face for the tube which lies directly opposite the end face in order to allow a stable structure of the heat exchanger, collecting boxes, and block.
Claims8
A heat exchanger, comprising a block having fins and rectangular tubes, wherein the block is arranged between a first collecting tank and a second collecting tank wherein the first and second collecting tanks are each closed off by a base, wherein each base comprises
- a central region extending along a length of the base,
- a first and second end side arranged on end regions of the base opposite one another,
- a plurality of rim holes sequentially arranged in the central region configured to receive the rectangular tubes of the block,
- a channel-shaped groove encircling the base configured to mate with an edge of the first or second collecting tank,
- a first and second elevation arranged centrally on the first and second end sides of the base such that each abuts a portion of the groove nearest to the first and second end side respectively, wherein the first and second elevations extend above the central region in a direction away from the collecting tank attached to the base.
