A heat exchanger is constituted by a plurality of interconnected heat exchange elements. Each element is a straight extruded tube (1) having cooling fins (2 and 2'). The fins (2 and 2') are provided, at their ends, with complementary interengageable means (3 and 7). Locking means (20) are provided for maintaining the engagement of said complementary means (3 and 7), thereby securing the elements together. In this way, a readily transportable, and easily assembled, cryogenic evaporator can be produced in any required size. <IMAGE> |
