Patent attributes
The invention relates to a frame part (10) for a tubular heat exchanger. The frame part (10) according to the invention is designed for being fastened (10) to a tubular body that is constituted of a number of parallel tubes through which a heat-exchange medium flows. The tubes run at both ends into a collecting tube which extends at an angle to the tubes. The tubular heat exchanger is provided with a frame part (10) on at least one of the sides of the tubular body that runs parallel to the tubes. Said frame part occludes the tubular heat exchanger from the exterior and can be at least indirectly linked with the collecting tubes. According to the invention, the frame part (10) has at least one predetermined breaking point (20). Said predetermined breaking point (20) is configured in such a mailer that, in the case of rupture, the frame part (10) is divided into two frame sections and that in the area of the predetermined breaking point (20) a frictional connection between the two otherwise separate frame sections is established.
