<p>PURPOSE:To facilitate assembly of an evaporator and also miniaturize the whole of it by fixing doughnut shaped fins to an inner pipe aligning to the inner pipe by shrinkage fitting and internally securing the inner pipe with fins to an outer cylinder. CONSTITUTION:Many doughnut shaped fins 82 are fixed to a single inner pipe 76 aligning to the inner pipe 76 by shrinkage fitting and this inner pipe 76 with fins 82 are internally secured to an outer cylinder 62. This leads to the formation of an evaporator comprising a single inner pipe 76 and fins 82 for facilitating assembly. And the reduction of quantity of components and machining portion facilitates premachining and moreover serves to comparatively miniaturize the whole of the evaporator.</p> |
