A vehicle radiator including inlet and outlet headers, a soldered core having a plurality of coolant flat tubes joining the inlet header and the outlet header with cooling fins on opposite sides of the coolant flat tubes, and a multifunction flat tube on at least one side of the core. The multifunction flat tube has a greater section modulus than the coolant flat tubes, and is soldered to adjacent cooling fins and the inlet and outlet headers whereby the multifunction flat tube carries coolant from the inlet header to the outlet header. The multifunction flat tubes each also have an inner flow resistance which is substantially smaller than the inner flow resistance of individual coolant flat tubes whereby more coolant flows through each multifunction flat tube than flows through an individual coolant flat tube per unit time.

A flexible tube comprising a skirt and a distribution head, resistant to cracking under stress and forming a barrier to water. The wall of the tube is made from at least one first polymer from the group of polypropylenes, with, at the mid-point from the end of the skirt furthest from the head to the end of the neck forming the distribution hole of the tube, a thickness of between 0.30 mm and 1.00 mm, with a section modulus of between 700 MPa and 80 MPa, the section moduli of the components of the wall being chosen to follow a law of maximum dispersion. The tube finds application in the storage of all products, in particular pasty bodies in cosmetics and pharmaceuticals.

A fixing device includes: a rotatable endless fixing belt; a nip forming member arranged inside the fixing belt; a facing rotating body that abuts the nip forming member via the fixing belt to form a nip portion with the fixing belt; a heat source that directly heats up the fixing belt at a portion other than the nip portion; and a supporting member that supports the nip forming member.
