[0002] Hot weather creates a huge demand for cold drinks, and cold drink dispensers have become a common device in modern society. Their primary function is to quickly cool drinks to meet consumer demand. The cooling system's ability to provide both rapid and continuous cooling is a key criterion for evaluating a cold drink dispenser.

[0003] However, most of the cold drink machines currently used mainly use the tube-plate type to achieve cooling. The tube-plate type is to attach metal tubes to a metal plate by welding or mechanical connection. The beverage box is placed on the metal plate, and the refrigerant is passed through the metal tubes. The beverage is cooled through multiple heat exchanges. The pipes are directly attached to the metal plate. The contact area in this process is limited, and the cold resistance of the cold transfer is large, resulting in reduced cooling efficiency. In addition, the cooling effect will deteriorate when the cold drink is continuously output. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a distributed cold drink machine with cross-pipes includes: a bottom bracket 1, a compressor 2, a condenser 5, a cast aluminum heat exchanger 8, a filter pump 3 and a fan 4.

[0025] The compressor 2 is fixed in the bottom bracket 1 , and the compressor 2 includes a compressor inlet 14 and a compressor outlet 13 .

[0026] Next, the condenser 5 is fixed in the bottom bracket 1 . The condenser 5 is provided with a condenser inlet 15 and a condenser outlet 16 . The condenser inlet 15 is communicated with the compressor outlet 13 . The pressurized gaseous refrigerant is condensed through the condenser 5 .

[0027] Secondly, the cast aluminum heat exchanger 8 includes a cold drink pipeline 10 and a refrigerant pipeline 11; the cold drink pipeline 10 is arranged in multiple layers, and each layer of cold drink pipeline 10 is spirally distributed along the vertical direction. The cold drink pipelines 10 are nested and connected by a U-shaped interface 22. A cold drink pipeline inlet 20 and a cold drink pipeline outlet 19 are provided on the cold drink pipeline 10; the refrigerant pipeline 11 is provided with a refrigerant pipeline inlet 17 and a refrigerant pipeline outlet 18. The refrigerant pipeline inlet 17 is connected to the condenser outlet 16, and the refrigerant pipeline outlet 18 is connected to the compressor inlet 14 to receive liquid refrigerant from the condenser 5 and return the heated gaseous refrigerant to the compressor inlet 14. The refrigerant pipeline 11 is wound around the cold drink pipeline 10 in a cross form.

[0028] Furthermore, the refrigerant pipe 11 is interleaved and wound around the multiple layers of cold drink pipes 10 in a cross-wrap pattern. In this embodiment, the refrigerant pipe 11 is interleaved and wound around the second and fourth layers of cold drink pipes 10 from the outside inward in a cross-wrap pattern. The exposed cold drink pipe 10 and the refrigerant pipe 11 on the upper side of the cast aluminum heat exchanger 8 are secured to each other via pipe fixing plate A 12. The upper sides of the cold drink pipe 10 and the refrigerant pipe 11 are secured to each other via pipe fixing plate B 23. The lower sides of the cold drink pipe 10 and the refrigerant pipe 11 are secured to each other via pipe fixing plate C 24. The front and rear sides and left and right sides of the cold drink pipe 10 and the refrigerant pipe 11 are secured to each other via external pipe fixing brackets 25. The interiors of the cold drink pipe 10 and the refrigerant pipe 11 are secured to each other via internal pipe fixing brackets 26. The heat transfer area between the cold drink pipeline 10 and the refrigerant pipeline 11 is increased, and the cold drink pipeline 10 is at the outermost layer, so that the cold drink pipeline 10 can fully absorb cold energy.

[0029] In this embodiment, the cast heat exchanger 8 is manufactured as follows: the refrigerant pipe 11 and the cold drink pipe 10 are arranged in a cross pattern, and then fixed with the pipe external fixing frame 25, the pipe internal fixing frame 26, the pipe fixing plate A12, the pipe fixing plate B23, and the pipe fixing plate C 24. The heat exchanger 8 is then cast with molten aluminum. The resulting cast aluminum acts as the medium between the pipe heat exchangers, thereby increasing the heat exchange area and efficiency, and having a cold storage capacity, making it suitable for both home and commercial use.

[0030] In this embodiment, the working process of the cast aluminum heat exchanger 8 is as follows: the low-temperature refrigerant in the refrigerant pipeline 11 exchanges heat with the cast aluminum, the refrigerant temperature increases, and the cast aluminum temperature decreases. The cast aluminum then exchanges heat with the cold drink in the cold drink pipeline 10, the cast aluminum temperature increases, and the cold drink temperature decreases. When the cast aluminum and the cold drink pipeline 10 are heat exchanged, the excess cooling capacity can be stored.

[0031] Furthermore, aluminum evaporator fins 9 are fixed on both sides of the cast aluminum heat exchanger 8 to increase the heat exchange area.

[0032] Furthermore, an evaporating dish 6 is provided below the condenser 5. An evaporator water pan 7 is also provided below the cast aluminum heat exchanger 8. This pan is equipped with an evaporator water pan pipeline 21, one end of which is connected to the upper surface of the evaporating dish 6. The cast aluminum heat exchanger 8 condenses moisture from the outside air. The evaporator water pan 7 collects moisture flowing down from the outside of the cast aluminum heat exchanger 8. This moisture then flows through the evaporator water pan pipeline 21 into the evaporating dish 6. The higher-temperature condenser 5 is located above the evaporating dish 6, where it is further evaporated.

[0033] Next, the inlet of the filter pump 3 is connected to the external cold drink pipeline, and the outlet of the filter pump 3 is connected to the inlet 20 of the cold drink pipeline.

[0034] Secondly, the fan 4 is located between the compressor 2 and the condenser 5 , and the fan 4 is used to dissipate heat from the condenser 5 .

[0035] In this embodiment, the flow process of the refrigerant is as follows: after being pressurized by the compressor 2, it flows out from the compressor outlet 13, enters the condenser 5 through the condenser inlet 15, and then flows out through the condenser outlet 16 after the heat dissipation is completed, enters the cast aluminum heat exchanger 8 through the refrigerant pipe inlet 17 for heat exchange, and then flows out through the refrigerant pipe outlet 18, enters the inside of the compressor 2 through the compressor inlet 14, and performs the next working cycle again.

[0036] The flow process of cold drinks: the external cold drinks are powered and filtered by the filter pump 3, enter the cast aluminum heat exchanger 8 through the cold drink pipeline inlet 20 for heat exchange, and then are taken away by consumers through the cold drink pipeline outlet 19 for drinking.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
