Heat exchanger and holder element for mounting same

摘要

The heat exchanger has cooling pipelines (104) arranged next to each other between two separation walls, and two collecting devices (102) for guiding liquid and arranged parallel to the walls, where the pipelines are connected with the walls. Two holding elements (506) have first fastening areas lying at end sections of the walls and second fastening areas engaging in elongated recesses (510) of the collecting devices. The holding elements have third fastening areas with apertures for retaining fastening areas of a module i.e. cooler, where the holding elements are formed as plastic holders.
