1. A thermal release element comprising a container body having an outer wall formed from a frangible material and a hollow space situated inside the container body enclosed by the outer wall, in which a release fluid is enclosed, wherein the container body is expanded in an axial direction with a tubular middle section extending in the axial direction and two end sections situated at each axial end, in which the hollow space is sealed in a cap-like manner, wherein the container body in the tubular middle section, as seen in a sectional plane transverse to the axial direction, has an outer contour of the outer wall that deviates from a circular or oval contour, wherein the end sections, in areas facing the middle section, each has a circular or an oval contour of the outer wall, as seen in the sectional plane transverse to the axial direction, wherein transitions zones are provided between the middle section and the end sections in which the outer contour of the outer wall, as seen in the sectional plane transverse to the axial direction, transitions from the shape of the middle section deviating from a circular or oval shape, into the circular or oval shape of the respective end section, wherein the transition zones have a longitudinal extension (L1, L2) in the axial direction of at least 1.5 mm. |
