Title:
HEAT EXCHANGER AND METHOD OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/007763
Kind Code:
A1
Abstract:
A method of producing a heat exchanger (1) having a heating tank (30) that has in
it a partitioned chamber for containing fluid, and heating the fluid, having
been led to the partitioned chamber, by heating the heating tank (30) from its
exterior. The method includes a superposing step and a tank forming step. In the
superposing step, metal plate-like members (10) having through-holes (20)
for allowing the fluid to pass are used, and the metal members (10) are superposed
such that, out of the metal members (10), metal members (10) in which their peripheral
edges (11) are less in thickness than portions inside the peripheral edges are
each used as at at least either of adjacent metal members (10). The tank forming
step constructs the heating tank (30) formed by integrating a wall of the partitioned
chamber and an outer wall of the heating tank (30), and this is performed by welding
the peripheral edges (11) of the adjacent metal members (10) together. The heat
exchanger can be produced simpler and can heat the fluid sufficiently.
