[0023] like Figures 1 to 3As shown, an evaporator according to a first aspect embodiment of the present invention includes an evaporator body 100, a first pipe fitting 200, and a second pipe fitting 300. The evaporator body 100 includes a heat-conducting inner liner 110 and an outer shell 120. The inner liner 110 has a material cavity 130 inside. The outer shell 120 is sleeved on the inner liner 110, and the outer shell 120 and the inner liner 110 enclose a heat exchange cavity 140. The heat exchange cavity 140 is arranged around the material cavity 130. The evaporator body 100 is provided with a portion of material that is uniformly distributed with respect to the heat exchange cavity. The first pipe 200 has an input port 141 and an output port 142 connected together. The first end of the first pipe 200 is used to connect to the refrigerant output end of the refrigeration device. The tail end of the first pipe 200 is welded to the evaporator body 100 and the pipe inside the first pipe 200 is connected to the input port 141. The first end of the second pipe 300 is used to connect to the refrigerant return end of the refrigeration device. The tail end of the second pipe 300 is welded to the evaporator body 100 and the pipe inside the second pipe 300 is connected to the output port 142.

[0024] The inner liner 110 can be made of stainless steel or other metal or alloy materials, which have high thermal conductivity. In some embodiments of this utility model, the outer shell 120 can be made of resin material with low thermal conductivity, thereby preventing external heat from being transferred to the refrigerant in the heat exchange chamber 140 and reducing the heat exchange efficiency of the refrigerant. The outer shell 120 can be heat-fused to the inner liner 110 to form the heat exchange chamber 140. In some embodiments of this utility model, the outer shell 120 can also be made of stainless steel or other metal or alloy materials, so that the inner liner 110 and the outer shell 120 can be laser-welded to form the heat exchange chamber 140, with a tight and stable connection, and the refrigerant is not easy to leak from the heat exchange chamber 140.

[0025] Both the first pipe fitting 200 and the second pipe fitting 300 can be made of metals or alloys such as copper. The refrigeration device can include conventional refrigeration components such as compressors and condensers. The first end of the first pipe fitting 200 can be connected to the refrigerant output end of the condenser, and the first end of the second pipe fitting 300 can be connected to the refrigerant return end of the compressor. Specifically, the refrigerant can be gaseous or liquid, which will not be elaborated here.

[0026] In this utility model evaporator, the inner liner 110 and the outer shell 120 are nested together, forming a heat exchange chamber 140 between them. The heat exchange chamber 140 and the material chamber 130 are separated only by the wall of the inner liner 110, and the structure is stable. The cooler refrigerant can be introduced into the heat exchange chamber 140 through the first pipe 200. After the material in the material chamber 130 exchanges heat with the refrigerant, the warmer refrigerant flows back to the refrigeration device through the second pipe 300. This design is compact and stable, and improves heat exchange efficiency.

[0027] In some embodiments of this utility model, when the evaporator is installed in equipment such as a cold drink manufacturing device, the inlet 141 is located below the outlet 142 in the direction of gravity. The refrigerant enters the heat exchange chamber 140 from the inlet 141. Under the action of gravity, the refrigerant will flow relatively slowly toward the outlet 142, which prolongs the time that the refrigerant is in the heat exchange chamber 140. The refrigerant can fully absorb the heat of the material and improve the heat exchange efficiency.

[0028] Specifically, the evaporator body 100 can be barrel-shaped or cylindrical. When the evaporator body 100 is vertically installed, the inlet 141 can be located at the bottom of the evaporator body 100, while the outlet 142 is located on the peripheral wall of the evaporator body 100. When the evaporator body 100 is horizontally installed, the inlet 141 can be located on the lower peripheral wall of the evaporator body 100, while the outlet 142 is located on the upper peripheral wall of the evaporator body 100.

[0029] In some embodiments of this utility model, such as Figure 3 As shown, the inner liner 110 is cylindrical, and the heat exchange cavity 140 surrounds the outer peripheral wall of the inner liner 110, thereby increasing the contact area between the refrigerant and the outer wall of the inner liner 110 and improving the heat exchange efficiency. Specifically, the heat exchange cavity 140 is annular and sleeved on the inner liner 110, which maximizes the heat exchange contact area.

[0030] Specifically, the outer casing 120 can be barrel-shaped, such as... Figure 3 As shown, the inner liner 110 is located inside the outer shell 120. The bottom edge of the inner liner 110 is ultrasonically welded to the bottom surface of the outer shell 120, while the upper edge of the inner liner 110 is turned outward and ultrasonically welded to the inner wall surface of the outer shell 120.

[0031] In an embodiment where the heat exchange chamber 140 is annular, the inlet 141 and the outlet 142 are arranged symmetrically around the central axis of the inner liner 110. The evaporator body 100 can be placed horizontally. In this case, the inlet 141 can be located below the heat exchange chamber 140, while the outlet 142 can be located above the heat exchange chamber 140. The inlet 141 and the outlet 142 can be arranged at the greatest possible distance. The refrigerant enters the heat exchange chamber 140 from the inlet 141 and can flow slowly along the outer peripheral wall of the inner liner 110 toward the outlet 142, uniformly covering most of the material chamber 130 and improving the cooling effect of the material chamber 130.

[0032] In some embodiments of this utility model, such as Figure 1 , 3 As shown, the tail end of the first pipe fitting 200 is welded to the inner peripheral wall of the inner liner 110; the tail end of the second pipe fitting 300 is welded to the inner peripheral wall of the inner liner 110.

[0033] Both the first fitting 200 and the second fitting 300 are welded to the inner circumferential wall of the inner liner 110 and will not protrude outward from the outer circumferential wall of the outer shell 120. This facilitates installation, prevents collisions with external objects, improves service durability, and also prevents external heat from entering and exchanging heat with the refrigerant through the first fitting 200 or the second fitting 300, thereby improving heat exchange efficiency and reducing energy consumption.

[0034] In some embodiments of this utility model, such as Figure 1 , 2 As shown, the first end of the evaporator body 100 is provided with a first opening 150 communicating with the material chamber 130. The evaporator body 100 is provided with a flange connection 400 at the position of the first opening 150. The first ends of the first pipe fitting 200 and the second pipe fitting 300 both extend toward the first opening 150.

[0035] The evaporator body 100 can be applied to a cold drink manufacturing device. The evaporator body 100 can be connected to the housing of the cold drink manufacturing device through the flange connection 400, thereby defining a material chamber 130 for placing materials. The first pipe 200 and the second pipe 300 can both have a bend. The first end of the first pipe 200 and the first end of the second pipe 300 both extend toward the first opening 150. The refrigeration device can be placed on the housing of the cold drink manufacturing device. The first pipe 200 and the second pipe 300 can pass through the housing to facilitate connection with the cold drink manufacturing device. Specifically, the outer shell 120 can be provided with an outward flange 410 at the edge of the first opening 150 to form a flange connection 400. The outward flange 410 is provided with an installation notch 420 for bolt connection with the flange.

[0036] In some embodiments of this utility model, the tail end of the evaporator body 100 is provided with a second opening 160 communicating with the material chamber 130, wherein the head end and the tail end of the evaporator body 100 are located on both sides of the material chamber 130.

[0037] In cold beverage manufacturing equipment, a stirring component is usually also provided. The stirring component is driven to rotate by a motor or rotary cylinder and other drive components. The stirring component extends from the second opening 160 into the material chamber 130, thereby stirring the material in the material chamber 130. By setting the first end of the evaporator body and the tail end of the evaporator body 100 opposite to each other, the stirring component extending from the second opening 160 is less likely to interfere with the first pipe 200 and the second pipe 300, ensuring stable internal refrigeration and stirring operations.

[0038] The cold drink manufacturing apparatus according to a second aspect of the present invention includes the evaporator disclosed in any of the above embodiments.

[0039] The cold drink manufacturing device typically includes a housing, a refrigeration unit, a stirring component, and a driving component. The driving component and the refrigeration unit are both located in the housing. The evaporator body 100 can be detachably installed in the housing via flanges, clips, screws, or other components. The driving component drives the stirring component to rotate, and the stirring component can extend into the material chamber 130 of the evaporator body 100. The refrigerant output end of the refrigeration unit is connected to the first end of the first pipe 200, and the refrigerant return end of the refrigeration unit is connected to the first end of the second pipe 300.

[0040] The present invention relates to a cold drink manufacturing apparatus that utilizes the evaporator disclosed in any of the above embodiments, which has a compact and stable structure and improves heat exchange efficiency.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
