[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-4 A multi-channel liquid condenser comprises a condenser body 2 and a load-bearing base 1. The bottom surface of the condenser body 2 is bolted with the load-bearing base 1. The inner wall of the condenser body 2 is provided with a linear auxiliary pipe 6 in a circumferential distribution. A U-shaped main pipe 9 is provided at the center position inside the condenser body 2. An annular flow guide pipe 10 is provided on the surface of the U-shaped main pipe 9. A connecting pipe 11 is provided circumferentially between the annular flow guide pipe 10 and the feed pipe 5. A plurality of groups of annular flow guide pipes 10 are uniformly distributed in a linear array on the surface of the U-shaped main pipe 9. A blast assembly 4 is provided on the side of the condenser body 2. The condenser main A U-shaped main pipe 9 is arranged at the center of the body 2 to cooperate with the annular guide pipe 10 for condensation treatment. At the same time, a straight auxiliary pipe 6 is arranged on the circumference of the inner wall of the condenser body 2 for condensation treatment. No baffle is required inside, and the gap between the annular guide pipe 10 and the U-shaped main pipe 9 is used for baffle. The whole device is provided with multiple channel structures for heat exchange treatment between the refrigerant and the heat medium, and an air cooling structure is arranged on the side for condensation treatment. The condensation treatment is carried out by condensing gas and liquid at the same time, which is convenient for rapid cooling of the liquid, has high condensation efficiency, and saves time.

[0025] In order to accelerate the heat exchange between the refrigerant and the heat medium of the entire device and improve the cooling efficiency, a blower assembly 4 is provided, including an air guide fan 401 and a U-shaped air duct 402. The air guide fan 401 is bolted to the surface of the load-bearing base 1, and the side of the air guide fan 401 is connected to a U-shaped air duct 402. A horn air guide head 403 is provided at the end of the U-shaped air duct 402, and the horn air guide head 403 is abutted against the side of the condenser body 2. The blower assembly 4 is used for air cooling to improve the condensation efficiency of the entire device. The specific structure is to accelerate the circulation of air through the air guide fan 401, and the external air volume enters the horn air guide head 403 along the U-shaped air duct 402, and the air volume is blown into the condenser body 2 through the horn air guide head 403 to realize air cooling heat exchange.

[0026] When the refrigerant and the heat medium of the whole device are exchanged for feeding, since the flanges at both ends of the condenser body 2 are connected with heat exchange floating heads 3, the two ends of the U-shaped main pipe 9 penetrate the top surface of the heat exchange floating head 3, and the two ends of the straight auxiliary pipe 6 penetrate the end of the condenser body 2 and are located inside the heat exchange floating head 3, the top surface of the heat exchange floating head 3 is provided with a liquid inlet auxiliary pipe 7 near the end of the U-shaped main pipe 9, and the bottom surface of the heat exchange floating head 3 is provided with a liquid discharge pipe 8, and the center of the top surface of the condenser body 2 is penetrated with a feed pipe 5, and the surface of the straight auxiliary pipe 6 is bolted to the inner wall surface of the condenser body 2 through a clamp, so the refrigerant is generally used. The refrigerant enters along the end of the U-shaped main pipe 9 and the liquid inlet auxiliary pipe 7. After entering the U-shaped main pipe 9, the refrigerant inside the U-shaped main pipe 9 covers the entire connecting pipe and the inside of the annular guide pipe 10. The refrigerant entering along the liquid inlet auxiliary pipe 7 first enters the inside of the heat exchange floating head 3, fills the inside of the heat exchange floating head 3, and then enters the end of the straight auxiliary pipe 6 through the heat exchange floating head 3, and randomly fills the entire liquid inlet auxiliary pipe 7. The heat medium enters through the feed pipe 5, contacts with the straight auxiliary pipe 6, the U-shaped main pipe 9, the annular flow and connecting pipe 11 surfaces, performs heat radiation cooling treatment, and is equipped with a blast assembly 4 for condensation cooling treatment.

[0030] An openable and closable sealing valve is arranged inside the liquid discharge pipe 8 to control the opening and closing of the liquid discharge pipe 8 , thereby realizing the discharge and closing of the liquid inside the heat exchange floating head 3 .

The specific position is generally set on both sides of the bottom surface of the condenser main body 2, that is, in this figure, close to the position on both sides of the outside of the load-bearing base 1. The specific position can be selected according to the actual use scenario. At the same time, the corresponding sealing valve needs to be set inside the valve at this position to control the opening and closing.

[0032] In summary:

[0033] A U-shaped main pipe 9 is arranged at the center position inside the condenser body 2 to cooperate with the annular guide pipe 10 for condensation treatment. At the same time, a straight auxiliary pipe 6 is arranged on the circumference of the inner wall of the condenser body 2 for condensation treatment. There is no need to set a baffle inside, and the baffle is used through the gap between the annular guide pipe 10 and the U-shaped main pipe 9. The whole device is provided with multiple channel structures for heat exchange between the refrigerant and the heat medium, and an air-cooling structure is arranged on the side for condensation treatment.
