Embodiment 1
[0034] Such as figure 1 As shown, an injector that automatically adjusts the area ratio with the generated temperature includes an injector cavity 1 including a working fluid inlet 1a, an injection fluid inlet 1b, a fluid outlet 1c, a working fluid nozzle 1d, and a diffuser chamber 1e, and The injector cavity 1 is connected with the temperature sensing package 2, the injector cavity 1 is divided into two spaces respectively connected with the temperature sensing package 2 and the working fluid inlet 1a, the diaphragm 3, the adjusting cone 4, and the spring 5;
[0035] The injection cavity 1 is divided into a steam chamber 101, an injection chamber 102, a mixing chamber 103 and a diffusion chamber 1e; the diaphragm 3 is arranged in the steam chamber 101, and the steam chamber 101 is divided into two parts: the active chamber 101a and the driven chamber 101b. Diaphragm 3 is an elastic sheet, metal sheet, plastic sheet, etc. can be used, and its surroundings are sealed and fixed ...
Embodiment 2
[0042] This embodiment is a specific application carried out on the basis of Example 1: a jet refrigerator using the ejector of Example 1, such as figure 2 shown in figure 1 On the basis of the shown system, it also includes a condenser 6, a throttle valve 7, an evaporator 8, a circulation pump 9, and a generator 10; the fluid outlet 1c of the ejector is connected with the inlet of the condenser 6, and the outlet of the condenser 6 is connected with the circulation The inlet of the pump 9 and the inlet of the throttle valve 7 are simultaneously connected, the outlet of the circulating pump 9 is connected with the inlet of the generator 10, the outlet of the generator 10 is connected with the working fluid inlet 1a of the injector, and the outlet of the throttle valve 7 is connected with the inlet of the evaporator 8 Through, the outlet of the evaporator 8 is connected with the injection fluid inlet 1b of the injector;
[0043] The temperature sensing bulb 2 is located on the...
Embodiment 3
[0048] Such as image 3 As shown, this embodiment is an improvement carried out on the basis of Example 2. The temperature-sensing package 2 is located on the wall of the generator 10. The heat exchange between the working fluids makes the pressure change in the temperature sensing bulb 2 more sensitive to the temperature change.
