勿論である。In the above description, the case where the high-temperature fluid 2 is mixed has been described. However, it goes without saying that the fluid mixer 17 of the present invention can be applied to a low-temperature fluid generator such as a refrigerator or an air conditioner. Of course, various changes can be made without departing from the spirit of the present invention.

成できるという優れた効果を奏し得る。The fluid mixer of the present invention has a cylindrical body having a closed wall at one end for deflecting the flow direction of the fluid and having a fixing flange formed on the outer periphery of the opening at the other end. Since it has a configuration in which a plurality of fluid mixing holes are formed on the outer periphery of the cylindrical main body, the fluid mixer is installed in the flow path such that the closed wall faces the upstream side of the fluid,
Alternatively, the fluid may be installed so as to face the downstream side of the fluid, or the obstruction wall may be installed so as to be located in the fluid outlet of the fluid generator, or the obstruction wall may be protruded into the fluid generator. By installing it at the outlet, effective mixing is achieved by the fact that the direction of fluid flow is deflected by the obstruction wall, and the deflected fluid is throttled and opened / expanded when passing through the fluid mixing hole. Therefore, it is possible to achieve an excellent effect that the uniformity of the temperature and the flow velocity of the fluid can be effectively achieved with a simple configuration.
