At the upper end of 11a, there is an inlet 12 for fresh liquid or gas to recover heat.
A pipe 14 to which new liquid or gas is sent by a pump 13 is connected.

Similarly, the heat exchanger of the present invention is constructed by sequentially providing communication passages for passing liquid or gas from the lower chamber to the upper chamber.

い高温にまで熱せられて、上部より排出する。 With the above configuration, when high-temperature waste liquid or exhaust gas is introduced into the evaporation chamber 16 having the evaporation part 1 of the heat pipe, the waste liquid or exhaust gas flows along the recessed part of the corrugated plate 4, and the drop port 8 at the end of the evaporation part 8 The flow direction is changed by the corrugated plate of the heat pipe assembly below, and it falls in a zigzag pattern. On the other hand, low-temperature new liquid or gas is pumped from below into each small chamber of the condensation chamber 9, flows into the inlet at the top of the small chamber, falls onto the heat pipe assembly, and changes the flow direction. The liquid and gas that accumulates at the bottom of the small chamber are sent to the small chamber above by a pump, and throughout the condensation chamber, new liquid and gas with a lower temperature than the lower part are generated. It is heated to a high temperature close to the temperature of the waste liquid and exhaust gas flowing into the condensing chamber, and then discharged from the top.

発部に戻る。 In this way, the heat of the waste liquid and exhaust gas is transferred to the evaporator section 1 of the heat pipe, evaporating the working fluid inside the heat pipe, and the evaporated vapor reaches the condensing section 2, where it is converted into a liquid that recovers the low-temperature heat in the condensing chamber. At the same time, the working fluid is condensed and returned to the evaporation section by the slope of the heat pipe.

中の小部屋から排出させてもよい。 Note that the heat pipe operates even if there is a slight temperature difference between the evaporation section and the condensation section, so even when the flow direction of the fluid in the evaporation chamber and the condensation chamber is reversed as in the present invention, the heat is transferred at the bottom of the heat exchanger. Heat is transferred well from the waste liquid or exhaust gas whose temperature has decreased through exchange to the new low-temperature liquid or gas that aims to recover heat, and the liquid or gas that has been heated sequentially from the bottom to the top of the heat exchanger. It also conducts heat well. If necessary, the heated liquid or gas may be discharged from a small chamber halfway through reaching an appropriate temperature.

埋めないで、気体や液体の流出口を形成する。 In this case, an outlet for gas or liquid is formed on the condensing part side of the central portion of the heat pipe by reducing the diameter of the heat pipe or by not filling the gap.

It is also possible to improve efficiency.
