ある。As described above, in the conventional apparatus, if heat exchange is performed directly in the pipe strength base material, the pipe strength base material is damaged by high-cycle thermal fatigue. A sleeve tube 2 is inserted into a strength base material 1 and gas and liquid are directly heat-exchanged therein.
However, it has the following disadvantages. 1. This is not applicable in the case of mixing conditions in which the gas side temperature is lower than the liquid side temperature to be mixed. 2. Even when the gas side temperature is higher than the liquid side temperature, it cannot be applied to the case of gas-liquid temperature where the entire liquid side cannot be vaporized or the mixing conditions based on the flow ratio. The present invention has been proposed in view of the above point, and in this kind of gas-liquid mixing device, the range of application of the gas-liquid mixing conditions is expanded, and further, the pipe strength base material is subjected to thermal fatigue in the device. The purpose is to improve the durability by protecting the battery from being damaged.
