A method for closing a fillable collecting tank, in particular a fillable collecting tank of a heat exchanger for storing a fluid, having walls forming the collecting tank, wherein one of the walls is formed as a baseplate having openings for receiving pipes, wherein a filling opening for adding the fluid is provided in one of the walls, wherein the filling opening can be closed by the provision of a closure element that can be inserted into the filling opening or can be placed onto the filling opening after the fluid has been added to the collecting tank. A heat exchanger is also provided.

1. A method for closing a fillable collecting tank or a fillable collecting tank of a heat exchanger for storing a fluid, with walls forming the collecting tank, the method comprising: forming one of the walls as a baseplate having openings for receiving tubes,providing a filling opening for adding the fluid in one of the walls; andclosing the filling opening via a closing element that is insertable into the filling opening or placed on the filling opening after the fluid has been added to the collecting tank,wherein the opening is sealed after the closing via a sealing component, the sealing component entirely covering a head of the closing element and a portion of an outer surface of the one wall provided with the filling opening, such that the sealing component is provided on the outer surface of the one wall around the closing element. 2. The method according to claim 1, wherein the closing element is a deformable closing element. 3. The method according to claim 2, wherein the filling opening is closed directly by the deformation of the deformable closing element. 4. The method according to claim 3, wherein the deformable closing element is inserted in the filling opening and is deformed in the filling opening or in the immediate vicinity of the filling opening to seal the filling opening. 5. The method according to claim 2, wherein the deformable closing element is placed in, at, or on the filling opening and wherein the closing element is deformed at a distance from the filling opening in order to close the collecting tank fluid-tight. 6. The method according to claim 1, wherein the sealing component is an adhesive. 7. The method according to claim 1, wherein the closing element is a substantially planar element, which is placed on the filling opening. 8. The method according to claim 7, wherein the planar element is a metal sheet made of aluminum or an aluminum alloy. 9. The method according to claim 7, wherein the element is attached to the collecting tank via welding. 10. The method according to claim 9, wherein the welding is an ultrasonic torsional welding or an ultrasonic longitudinal welding. 11. A method for closing a fillable collecting tank or a fillable collecting tank of a heat exchanger for storing a fluid, with walls forming the collecting tank, the method comprising: forming one of the walls as a baseplate having openings for receiving tubes,providing a filling opening for adding the fluid in one of the walls; andclosing the filling opening via a closing element that is insertable into the filling opening or placed on the filling opening after the fluid has been added to the collecting tank,wherein the closing element is a deformable closing element,wherein the closing element is deformed at a distance from the filling opening in order to close the collecting tank fluid-tight,wherein the closing element is a hollow tube that is connected at a first end to the filling opening and that extends to a second end that is provided outside of the collecting tank and the hollow tube is closed in a region spaced apart from the filling opening,wherein the region of the hollow tube that is spaced apart from the filling opening is provided outside of the collecting tank and is positioned closer to the second end of the hollow tube than the first end of the hollow tube,wherein the hollow tube is closed by deforming sides of the hollow tube inward in a direction towards a central axis of the hollow tube in the region spaced apart from the filling opening, andwherein after the sides of the hollow tube are deformed inward in the region spaced apart from the filling opening, the hollow tube is bent to form a bend in the hollow tube. 12. A heat exchanger comprising: at least one fillable collecting tank for storing a fluid, with walls forming the collecting tank, wherein one of the walls is formed as a baseplate having openings for receiving tubes, wherein a filling opening for adding the fluid is provided in one of the walls, wherein the filling opening is closed with a deformable closing element, and wherein a sealing component is provided, the sealing component entirely covering a head of the closing element and a portion of an outer surface of the one wall provided with the filling opening, such that the sealing component is provided on the outer surface of the one wall around the closing element. 13. The method according to claim 11, wherein the bend is provided at a second region of the hollow tube that is provided outside of the collecting tank and is between the filling opening and the region spaced apart from the filling opening that includes the deformed sides of the hollow tube.
