摘要

The pipe has an end region (22) including a large contact surface provided in thermal contact with a heat source i.e. LED, or with a cooling body. An enlargement unit is provided with a flange-element (6) for enlarging the contact surface, where the flange-element is made of copper or aluminum. The flange-element is directly connected with an elongated base body (4) by a soldered connection, adhesive joint or crimp connection. The flange-element includes a recess (10) for form-fit connection with the heat source or with the cooling body.
