a tank which is provided in a heat receiving section configured to recover exhaust heat from a cooling object, and has a refrigerant vapor inflow section into which a refrigerant vapor flowing out from the heat receiving section via a vapor pipe is introduced, and a refrigerant gas outflow section from which the refrigerant gas of the refrigerant vapor is discharged, the tank being capable of storing refrigerant liquid of the refrigerant vapor on a lower surface; and
a regulating valve which floats on the refrigerant liquid stored in the tank and closes a space between the vapor pipe and the tank.
2. The gas-liquid separation device according to claim 1 , wherein the regulating valve has a ring shape.
3. The gas-liquid separation device according to claim 1 , wherein the regulating valve is inserted into a protruding section of the vapor pipe which protrudes into the tank.
4. The gas-liquid separation device according to claim 3 , wherein the regulating valve has a seal section which seals the refrigerant liquid between the regulating valve and the protruding section.
5. A rear door comprising:
a heat receiving section configured to recover exhaust heat from a cooling object;
a vapor pipe being connected to the heat receiving section; and
