[0019] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] Combination Figure 1-3 As shown, a double-layer liquid storage dryer includes a gland 1, an inner tank 2 and an outer tank 3. The outer tank 3 is placed on the outside of the inner tank 2. The tops of the inner tank 2 and the outer tank 3 are sealed with the gland 1. A liquid suction pipe 4 is provided in the inner tank 2. The liquid suction pipe 4 is connected to the output port on the gland 1. A gap is maintained between the inner wall of the outer tank 3 and the outer wall of the inner tank 2, and the gap forms a low-temperature and low-pressure medium channel 5. The outer tank 3 is also provided with an input interface 6 and an output interface 7.

[0021] The working principle of the above structure is: the high-temperature and high-pressure medium is input into the inner tank 2 from the input port, and the low-temperature and low-pressure medium is input between the inner tank 2 and the outer tank 3 from the input interface 6. The low-temperature and low-pressure medium exchanges heat with the inside of the inner tank 2 when passing through the low-pressure medium channel 5, so that the high-temperature and high-pressure medium is quickly cooled down and the temperature of the low-temperature and low-pressure medium 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 inner tank 2, and is sucked out from the output port by the suction pipe 4.

[0022] The beneficial effects of the above structure are: the utility model has a simple structure and a reasonable layout. Through the arrangement of the inner tank 2 and the outer tank 3, the liquefaction of the high-temperature and high-pressure medium and the heating of the low-temperature and low-pressure medium inside the liquid storage dryer 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.

[0023] In another embodiment, a plurality of partitions are arranged between the inner tank 2 and the outer tank 3 to enhance the strength of the entire dryer, separate the low-temperature and low-pressure medium channel 5 into multiple channels, and enhance the heat exchange efficiency.

[0024] In another embodiment, a spiral partition is provided between the inner tank 2 and the outer tank 3, which can also enhance the strength of the entire dryer and enhance the heat exchange efficiency, and make the entire low-pressure medium channel 5 spiral, so as to extend the time required for the output of the low-pressure medium, and make the heat exchange between the low-pressure medium and the high-temperature medium more thorough.

[0025] In another embodiment, heat exchange fins are further provided on the outside of the outer tank 3 .

[0026] In another embodiment, the heat exchange fins are corrugated fins or stacked fins.

[0027] In another embodiment, if Figure 1 and Figure 2 As shown, a drying bag 8 is also included. The drying bag 8 is arranged in the inner tank 2. Baffles 9 are respectively provided at the upper and lower ends of the drying bag 8. The two baffles 9 are used to limit the drying bag 8.

[0028] In another embodiment, the pipette 4 is inserted into the pressure cover 1, the bottom of the pipette 4 abuts against the bottom of the inner tank 2, and a pipette hole is provided on the bottom side of the pipette 4 to facilitate the assembly of the pipette 4.

[0029] In another embodiment, if Figure 3 As shown, the gland 1 is also provided with a temperature and pressure sensor 10 for outputting the temperature and pressure data in the tank body to the controller.

[0030] In another embodiment, if Figure 3 As shown, it also includes a sight glass 11, which is fixed on one side of the outer tank 3 and whose inner end is connected to the interior of the inner tank 2, so that the staff can observe the internal condition of the inner tank 2 in real time.
