[0021] Combination Figure 1-3 As shown, an internally cooled liquid storage dryer comprises a tank body 1, a gland 2, a bottom plate 3 and a low-pressure pipe 4, wherein a liquid suction pipe 5 is arranged inside the tank body 1, and the liquid suction pipe 5 is connected to the output port on the gland 2, and the two ends of the low-pressure pipe 4 are respectively connected to the gland 2 and the bottom plate 3, and the connection between the low-pressure pipe 4 and the gland 2 and the bottom plate 3 is respectively sealed, and the low-pressure pipe 4 at the two connection points respectively forms a joint or an interface, and the low-pressure pipe 4 is also provided with a heat exchange fin 6;

[0022] A drying bag 7 is also provided in the tank body 1 , and the upper end of the heat exchange fin 6 extends to the drying bag 7 , and a gap is maintained between the lower end of the heat exchange fin 6 and the bottom of the tank body 1 to avoid affecting the suction pipe 5 to suck out the liquid medium.

[0023] 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 low-pressure pipe 4. When the low-temperature and low-pressure medium passes through the low-pressure pipe 4, it exchanges heat with the inside of the tank body 1 through the low-pressure pipe 4 and the heat exchange fins 6, 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 7 and accumulated at the bottom of the tank body 1, and is sucked out from the output port by the liquid suction pipe 5.

[0024] The beneficial effects of the above structure are: the utility model has a simple structure and a reasonable layout. Through the arrangement of the low-pressure pipe 4, 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, if Figure 1 As shown, the low-pressure pipe 4 is coaxially arranged with the tank body 1, and the liquid suction pipe 5 is arranged on one side of the low-pressure pipe 4, so that the low-pressure pipe 4 can adopt a larger caliber and is easy to assemble.

[0027] Optionally, the low-pressure pipe 4 is a straight pipe.

[0028] Optionally, the portion of the low-pressure pipe 4 located below the drying bag 7 is a straight pipe, and the portion of the low-pressure pipe 4 located above the drying bag 7 is a spiral pipe, so as to increase the length of the low-pressure pipe 4 in the tank body 1 and thereby improve the heat exchange efficiency.

[0029] In another embodiment, in combination Figure 1 and Figure 2 As shown, baffles 8 are respectively provided at the upper and lower ends of the drying bag 7 , and the two baffles 8 are used to limit the drying bag 7 , and the upper ends of the heat exchange fins 6 are in contact with the baffles 8 .

[0030] In another embodiment, in combination Figure 1 and Figure 2 As shown, a base 9 is fixed at the connection between the low-pressure pipe 4 and the bottom of the tank body 1, and the bottom of the heat exchange fin 6 abuts against the base 9 to limit the bottom of the heat exchange fin 6 and maintain a suitable distance between the heat exchange fin 6 and the bottom of the tank body 1.

[0031] Optionally, the heat exchange fins 6 are corrugated fins or stacked fins.

[0032] In another embodiment, if Figure 3As 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.

[0033] In another embodiment, if Figure 3 As shown, a sight glass 11 is also provided on one side of the tank body 1 to facilitate the staff to observe the internal conditions of the tank body 1 in real time.
