Patent Searching and Data


Title:
LAMINATED EVAPORATOR
Document Type and Number:
Japanese Patent JPH062987
Kind Code:
A
Abstract:

PURPOSE: To allow condensed water to drop along a groove up to a lowermost part of an evaporator and to prevent scattering of water droplets by forming at least one or more grooves on linear passages in parallel with a groove for sealing an outer periphery of a refrigerant tube and a groove for forming a partition between the linear passages to be brazed to one another.

CONSTITUTION: A laminated evaporator comprises many laminated refrigerant tubes. A pair of molded plates 1A are connected to the tubes, a refrigerant passage is formed therebetween, and a wavy molded plate 2A is inserted into a linear passage of the refrigerant passage. On the other hand, a groove 3 for sealing an outer periphery of the tube and a groove 4 for forming a partition between linear passages are arranged to be brazed to one another. In this case, at least one or more grooves 5 are formed on the linear passage in parallel with the grooves 3, 4. Thus, water condensed on a heat transfer surface is fed down from the surfaces of the tubes through the grooves 5 and hence to prevent scattering of the condensed water rearward by an air flow.
