<p>PURPOSE:To provide a heat exchanger which may not affect a bad influence over a heater and a circulation pump but may show a fast rising in operation by a method wherein the heater is arranged at a suction port side of the circulation pump and at the same time an intake port of thermal medium liquid for the heater is arranged over the heater. CONSTITUTION:Thermal medium liquid heated by an electric heater 32 is ascended up to the lower surface of a partition wall 31 of a lower chamber 30B, a thermal distribution is distributed downwardly in sequence from a hot thermal medium liquid to a cold thermal medium liquid, the hot thermal medium liquid is sucked in sequency by the circulation pump 14 and then circulated in the circulation pipe line. In turn, the thermal medium liquid circulated in the circulation pipe line is flowed from the flow inlet 30a to the upper chamber 30A of the heater 10. The thermal medium liquid stored in the upper chamber 30A is stored, its flow speed is decreased, and as shown by an arrow A, the thermal medium liquid is flowed down gradually to the base part of the electric heater 32 through a communication hole 31a and then heated. The thermal medium liquid heated and ascended up to the lower surface of the partition wall of the lower chamber 30B heats the thermal medium liquid stored in the upper chamber 30A via partition wall 31, so that it is possible to prevent a useless discharging of heat.</p> |
