1. A device for thermal joining of a heat exchanger for a motor vehicle, having a first locating element, a second locating element and at least one heat source,
wherein each of the first and second locating elements have at least one thermal insulation and are configured to mutually align with contact surfaces for arranging an object to be joined between the contact surfaces,
wherein at least one locating element is configured to movably in relation to the other locating element,
wherein the at least one heat source, a first thermal mass and a second thermal mass which are heatable by the at least one heat source are integrated into the first locating element,
wherein the second locating element is comprises a support element with a contact surface for the object,
wherein the first thermal mass of the first locating element comprises a contact surface for the object for heating the object via heat conduction,
wherein the second thermal mass is arranged on the same side of the object with respect to the first thermal mass, the first thermal mass is configured to evenly distribute heat within the object, and the second thermal mass is configured to evenly distribute heat within the first thermal mass;
wherein the first thermal mass and the second thermal mass are plate-shaped,
wherein the first locating element has a first thermal insulation and a second thermal insulation, and
wherein the second thermal insulation is formed of a first layer and a second layer.
