Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration evaporator. Background Technology

[0002] The working principle of an ice cream machine is as follows: First, the ingredients are added to the ingredient tank. Then, the ingredients are mixed evenly with air by an air-milk pump and conveyed to the refrigeration tank. The expanded milk mixture is stirred and gradually cooled in the freezing tank, while its viscosity increases. When the desired viscosity is reached, it is pushed to the outlet by a screw conveyor. Then, the outlet is opened, and the machine extrudes the finished ice cream.

[0003] In the existing technology, most refrigeration tanks used for refrigeration directly inject the refrigerant into a set of pipes. The pipes are in close contact with the refrigeration tank for refrigeration. There is also a pipe body between the pipes and the refrigeration tank. During the heat exchange process, the refrigerant also needs to conduct heat through the pipe body. In addition, there is a gap between the pipe body and the refrigeration tank, resulting in low heat conduction efficiency and poor refrigeration effect. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0027] Example 1:

[0028] like Figures 1 to 3 As shown, this embodiment provides a refrigeration evaporator, including a shell body 1 and a bushing 2 for refrigerant flow. A hollow receiving cavity is defined inside the shell body 1. The bushing 2 is fitted inside the shell body 1. An inlet 21 and an outlet 22 are provided on the bushing 2. At least one groove 3 is recessed vertically on the outer side wall of the bushing 2. Each groove 3 is arranged in a serpentine manner to form a serpentine structure. The inlet end of each groove 3 is connected to the inlet 21, and its outlet end is connected to the outlet 22. The outer end of each groove 3 is an open end. The outer side wall of the bushing 2 is connected to the inner side wall of the shell body 1 to form a flow channel for each groove 3.

[0029] In this embodiment, by fitting the bushing 2 inside the shell body 1, the food is separated from the bushing 2, thus preventing the bushing 2 from contaminating the food inside the shell body 1 due to long-term dirt accumulation, thereby effectively improving the quality of the food. Secondly, at least one groove 3 with a serpentine structure is arranged vertically on the outer wall of the bushing 2. The inlet end of each groove 3 is connected to the inlet port 21, and its outlet end is connected to the outlet port 22. The outer wall of the bushing 2 is connected to the inner wall of the shell body 1 to form an independent flow channel for each groove 3. This allows the external refrigerant to enter the flow channel through the inlet port 21, and then the refrigerant can quickly flow to the outlet port 22 and then be delivered to the evaporator through the outlet port 22. Since each groove 3 is arranged in a serpentine structure, the length of the refrigerant flow channel is effectively increased, thereby effectively improving the cooling effect. Its structure is simple and allows for rapid delivery of refrigerant, thereby achieving efficient cooling and further improving the quality of the food.

[0030] Furthermore, the groove 3 is inclined in the vertical direction.

[0031] Preferably, when there is only one groove 3, the inlet 21 and the outlet 22 are respectively spaced at the upper end of one side of the outer wall of the bushing 2.

[0032] Specifically, it also includes a feed pipe 4 and a discharge pipe 5, wherein one end of the feed pipe 4 is connected to the external refrigerant and the other end is connected to the inlet 21, and one end of the discharge pipe 5 is connected to the outlet 22 and the other end is connected to the evaporator.

[0033] Preferably, the diameter of the feed pipe 4 is smaller than the diameter of the discharge pipe 5.

[0034] Specifically, it also includes a conveying pipe, with an inlet 11 provided on the lower end wall of the shell body 1. The conveying pipe is connected to the inlet 11 to convey external ingredients into the shell body 1 through the inlet 11.

[0035] In this embodiment, since the inlet 21 and outlet 22 are respectively arranged at the upper end of one side of the outer wall of the bushing 2, one end of the groove 3 is connected to the inlet 21. Then, the groove 3 extends from top to bottom and is inclined. Then, the groove 3 is bent to the left or right and continues to extend from bottom to top. This cycle continues until the other end of the groove 3 is connected to the outlet 22. Thus, the groove 3 makes multiple detours in the vertical direction to form a serpentine structure. Through the cooperation between the outer wall of the bushing 2 and the inner wall of the shell body 1, each groove 3 forms an independent flow channel, effectively increasing the length of the refrigerant flow channel.

[0036] In addition, since the refrigerant in the flow channel is in direct contact with the outer wall of the shell body 1, the traditional use of pipes as intermediate medium is reduced, and the contact area between the refrigerant in the flow channel and the barrel body is larger, resulting in higher heat exchange efficiency.

[0037] In this embodiment, a connecting pipe and an output connector are respectively provided on the outer side of the bushing 2. The upper end of the connecting pipe is fixedly installed on the inlet 21, and its lower end extends downward and is bent to form a bend, so that the connecting pipe can be connected to the feed pipe 4 through the bend. At the same time, one end of the output connector is fixedly installed on the outlet 22, and the discharge pipe 5 is connected to the outlet 22 through the output connector, which facilitates the assembly of the feed pipe 4 and the discharge pipe 5, thereby effectively improving the assembly efficiency. More preferably, the material of the connecting pipe is different from that of the feed pipe 4, and the material of the output connector is different from that of the discharge pipe 5. Since the feed pipe 4 and the discharge pipe 5 are preferably made of copper, the material of the connecting pipe and the output connector can be preferably made of stainless steel, thereby effectively reducing the production cost of the product while maintaining the cooling effect. In addition, of course, in order to effectively improve the cooling effect, the material of the connecting pipe can also be set to be the same as that of the feed pipe 4, that is, the material of the connecting pipe can also be made of copper. More preferably, since the diameter of the feed pipe 4 is smaller than the diameter of the discharge pipe 5, the cross-sectional area of ​​the inlet 21 is smaller than the cross-sectional area of ​​the outlet 22, thereby achieving the purpose of rapid cooling.

[0038] Example 2:

[0039] like Figures 4 to 6 As shown, this embodiment provides a refrigeration evaporator, which is similar to the first embodiment in that the bushing 2 is fitted inside the shell body 1, thus separating the food from the bushing 2 and preventing the bushing 2 from contaminating the food inside the shell body 1 due to long-term dirt accumulation. Secondly, at least one groove 3 with a serpentine structure is arranged in a vertical direction on the outer wall of the bushing 2. The inlet end of each groove 3 is connected to the inlet port 21, and its outlet end is connected to the outlet port 22. The outer wall of the bushing 2 is connected to the inner wall of the shell body 1 so that each groove 3 forms an independent flow channel, so that the external refrigerant enters the flow channel through the inlet port 21. In this way, the refrigerant can flow quickly through the flow channel to the outlet port 22, and then be delivered to the evaporator through the outlet port 22. Since each groove 3 is arranged in a serpentine structure, the length of the refrigerant flow channel is effectively increased, thereby effectively improving the refrigeration effect.

[0040] Unlike Embodiment 1, there are two grooves 3.

[0041] Specifically, when there are two grooves 3, the input ends of the two grooves 3 are connected to the input port 21 respectively, and the output ends of the two grooves 3 are connected to the output port 22 respectively.

[0042] Furthermore, the inlet 21 is located at the lower end of the outer wall of the bushing 2, and the outlet 22 is located at the upper end of the outer wall of the bushing 2.

[0043] Preferably, the two grooves 3 have the same detour direction.

[0044] Specifically, the two grooves 3 have opposite detour directions.

[0045] In this embodiment, since the inlet 21 is located at the lower end of the outer wall of the bushing 2 and the outlet 22 is located at the upper end of the outer wall of the bushing 2, one end of each of the two grooves 3 is connected to the inlet 21. Then, one of the grooves 3 extends downward from top to bottom and is inclined, then bends to the left and continues to extend upward from bottom to top. Next, the other groove 3 extends downward from top to bottom and is inclined, then bends to the right and continues to extend upward from bottom to top. This cycle continues until the other ends of the two grooves 3 are connected to the outlet 22. In this way, the two grooves 3 make multiple detours in the vertical direction, and the detours of the two grooves 3 are in opposite directions, so that the two grooves 3 form a serpentine structure. Through the cooperation between the outer wall of the bushing 2 and the inner wall of the shell body 1, each groove 3 forms two independent flow channels, thereby further ensuring the cooling effect.

[0046] Furthermore, if the two grooves 3 have the same direction of detour, then one end of each groove 3 is connected to the input port 21. Then, the two grooves 3 extend downwards and are set at an angle. Then, they bend to the left or right simultaneously and continue to extend upwards. This cycle continues until the other end of each groove 3 is connected to the output port 22. In this way, even if the two grooves 3 detour multiple times in the vertical direction and the detour direction of the two grooves 3 is the same, the two grooves 3 will form a serpentine structure.

[0047] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
