Title: Heat exchanger
Inventor: MORIKAWA MASARU
IPC: F28D15/02
Filed: 1990-03-02
Abstract: PURPOSE:To prevent in-pipe pressure from being increased following the temperature rise of a heat transfer medium when the flows of high and low temperature fluids are interrupted by connecting the medium inlet and outlet sides of a group of condensation pipes and further providing a condenser in the course of the bypass piping. CONSTITUTION:A bypass piping 12 connects between the medium inlet side and medium outlet side of a group of condenser pipes 4, and a condenser 13 is provided in the middle of the bypass piping 12. In a normal operation, heat transfer medium in a group 3 of evaporation pipes receives heat from a high temperature fluid 9 outside the pipe and is evaporated, and is further fed to the group 4 of the condenser pipes 4 through a vapor stream piping 7, whereby a low temperature fluid 10 outside the pipes is supplied with the heat for its condensation. Provided flow of the high temperature fluid 10 is interrupted owing to any inconvenience of the device, the heat transfer medium is evaporated by excess heat of the high temperature fluid 9 and is forced to flow to the group 4 of the condenser pipes through a vapor piping 7, but the vapor is not condensed in the group of the condensation pipes to raise heat transfer medium temperature (pressure). A thermometer 14 measures the temperature and forces an adjustment valve 15 to be opened when the temperature reaches a predetermined one for supply of cooling water to the condenser 13. Hereby, the vapor is condensed to lower medium temperature (pressure).
