Matrix heat exchanger, combination thereof, and method of manufacturing matrix heat exchanger

摘要

PROBLEM TO BE SOLVED: To provide a matrix type heat exchanger which has a large heat transfer area, although small in size, and facilitates heat transfer substantially without missing a point of thermal equilibrium between the steam side and the liquid film side and further which distributes steam and a liquid equally and can construct a large-scale heat exchanger easily, and a manufacture thereof. SOLUTION: Liquid collecting grooves 6 are provided on the upper side of a matrix structure 1 constructed of a thin plate 3 and thin plates 5 and in a part wherein they traverse some passage opening part 2a out of passage opening parts 2a and 2b of a plurality of passages piercing the structure in the vertical direction. On the occasion when a fluid of a two-phase flow of vapor and liquid is received, the liquid is brought into the liquid collecting grooves 6 by surface tension on the upper side of the matrix structure 1. The fluid in the liquid collecting grooves 6 flows into the passages in the matrix structure 1 which open in channels of the liquid collecting grooves 6. Therefore, uniform distribution of the vapor and the liquid to the passages in a plurality is enabled.
