Patent JP-2002206891-A (JP)
Title: Heat exchanger
Inventor: GOTO TAKAHARU
IPC: F28F9/22
Filed: 2001-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger having improved response properties from the supply of fuel to its evaporation with a simple configuration. SOLUTION: Fuel that flows into a dispersion space section 7 from a header inlet section 3a is branched into a fluid passage 5 that is branched and formed and flows into a lower heat exchange section 6 from a number of openings 4. At this time, since the volume of a passage section where fluid in the header section passes is minimized as required by the limited fluid passage 5, the fluid supplied to the header section 1 rapidly reaches the heat exchange section 6. Therefore, when the heat exchanger is applied as the evaporator of a fuel cell, response time from the supply of the fuel to the acquisition of an evaporation fuel can be reduced surely for quickening the activation of the fuel cell.
