[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] Combination Figure 1 and Figure 2 As shown, a liquid storage dryer with a U-shaped inner tube includes a tank body 1, a gland 2 and a U-shaped low-pressure tube 3, wherein a liquid suction tube 4 is arranged in the tank body 1, and the top of the liquid suction tube 4 is connected to the output port on the gland 2, and the gland 2 is also provided with an input interface 5 and an output interface 6 corresponding to the low-pressure tube 3, and the two ends of the low-pressure tube 3 are respectively connected to the input interface 5 and the output interface 6;

[0022] A square boss 7 is also provided on the top of the gland 2, and the input interface 5 and the output interface 6 are respectively arranged close to two symmetrical corners of the square boss 7 to reduce the manufacturing cost of the gland 2, ensure the strength of the gland 2, and maximize the outer diameter of the U-shaped low-pressure pipe 3;

[0023] The tank body 1 is also provided with a drying bag 8, which is arranged at the lower end of the tank body 1, so that the gaseous high-temperature and high-pressure medium entering the tank body 1 can first contact with the low-pressure pipe 3 as much as possible for heat exchange and liquefaction, and then be dried by the drying bag 8 and enter the lower end of the tank body 1.

[0024] The working principle of the above structure is: the high-temperature and high-pressure medium is input into the tank body 1 from the input port, and the low-temperature and low-pressure medium passes through the tank body 1 through the input interface 5, the low-pressure pipe 3, and the output interface 6. After the high-temperature and high-pressure medium enters the tank body 1, it exchanges heat with the low-pressure pipe 3, so that the high-temperature and high-pressure medium is quickly cooled, and the temperature of the low-temperature and low-pressure medium in the low-pressure pipe 3 is increased; the high-temperature and high-pressure medium is quickly liquefied and dried by the drying bag 8 and accumulated at the bottom of the tank body 1, and is sucked out from the output port by the liquid suction pipe 4.

[0025] The beneficial effects of the above structure are: the utility model has a simple structure and a reasonable layout. Through the arrangement of the U-shaped low-pressure pipe 3, the liquefaction of the high-temperature and high-pressure medium passing through the tank body 1 and the heating of the low-temperature and low-pressure medium are accelerated at the same time, which can effectively improve the working efficiency of the automobile air conditioner and has a certain energy-saving effect.

[0026] In another embodiment, heat exchange fins are further fixed on the low-pressure pipe 3 to further improve the heat exchange efficiency of the low-pressure pipe 3 .

[0027] Optionally, the heat exchange fins are corrugated fins or stacked fins.

[0028] In another embodiment, if Figure 1 As shown, a distance is maintained between the bottom of the low-pressure pipe 3 and the bottom of the tank body 1 .

[0029] In another embodiment, the suction pipe 4 and the low-pressure pipe 3 are both plugged into the pressure cover 2, the bottom of the suction pipe 4 abuts against the lower end of the tank body 1, and a suction hole is provided on the bottom side of the suction pipe 4 to facilitate the assembly of the suction pipe 4.

[0030] Optionally, the portion of the low-pressure pipe 3 located above or below the drying bag 8 is a spiral pipe, so as to increase the length of the low-pressure pipe 3 in the tank body 1, thereby improving the heat exchange efficiency.

[0031] In another embodiment, baffles 9 are respectively provided at the upper and lower ends of the drying bag 8 , and the two baffles 9 are used to limit the position of the drying bag 8 .

[0032] In another embodiment, if Figure 2 As shown, the gland 2 is also provided with a temperature and pressure sensor 10 for outputting the temperature and pressure data in the tank body 1 to the controller.
