Description

Technical Field

[0001] The utility model relates to an extrusion-type ice-making evaporator with high heat exchange efficiency. Background Art

[0002] Screw extruder ice making machine is a popular refrigeration equipment, widely used in cold drinks, performances and other fields. As a refrigeration equipment, the evaporator is an indispensable component. The function of the evaporator is to absorb heat by evaporating the liquid refrigerant and turn it into gas, thereby reducing the temperature of the water.

[0003] At present, the refrigerant in the screw extrusion ice machine is in a long and thin evaporator tube, which is spirally coiled on a cylinder through which the liquid to be cooled passes. Although this evaporator can achieve the evaporation effect, since the refrigerant is in one evaporator tube, the high-temperature refrigerant after vaporization needs to move in the spiral pipe for a long time and cannot be removed in time, which affects the heat exchange efficiency. Summary of the invention

[0004] The utility model aims to provide an extrusion-type ice-making evaporator with high heat exchange efficiency, comprising a cylinder, a refrigerant diversion box is provided on one side of the cylinder, a refrigerant collection box is provided on the other side of the cylinder, a plurality of evaporator tubes are connected between the refrigerant diversion box and the refrigerant collection box, and each of the evaporator tubes is wrapped around the outer wall of the cylinder for one circle.

[0005] Preferably, the plurality of evaporator tubes are arranged vertically, the inner diameter of the lowest evaporator tube is larger than the inner diameters of the other evaporator tubes, and the inner diameters of the other evaporator tubes are equal.

[0006] Preferably, the refrigerant diversion box is connected to a refrigerant input pipe.

[0007] Preferably, the refrigerant collecting box is connected to a refrigerant output pipe.

[0008] The advantages and beneficial effects of the utility model are: it provides an extruded ice-making evaporator with high heat exchange efficiency. By changing the structure of the evaporator, the refrigerant contacts the cylinder through multiple evaporator tubes, and each evaporator tube only surrounds the outside of the cylinder once. The refrigerant is quickly discharged after absorbing heat, which greatly improves the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0011] The technical solution specifically implemented in this utility model is:

[0012] like Figure 1 As shown, an extrusion-type ice-making evaporator with high heat exchange efficiency includes a cylinder 1, a refrigerant diverter box 2 is provided on one side of the cylinder 1, a refrigerant collecting box 3 is provided on the other side of the cylinder 1, and a plurality of evaporator tubes 4 are connected between the refrigerant diverter box 2 and the refrigerant collecting box 3, and each of the evaporator tubes 4 is wrapped around the outer wall of the cylinder 1 in a circle.

[0013] The above-mentioned multiple evaporator tubes 4 are arranged up and down, the inner diameter of the bottom evaporator tube 4 is larger than the inner diameter of other evaporator tubes 4, and the inner diameters of other evaporator tubes 4 are equal; in actual use, the water to be cooled flows from bottom to top in the cylinder 1, and the bottom evaporator tube 4 exchanges heat with the water with the highest temperature. The inner diameter of the bottom evaporator tube 4 is the largest, the refrigerant flow rate in the bottom evaporator tube 4 is the largest, and the heat absorption effect is good.

[0014] The refrigerant diverter box 2 is connected to a refrigerant input pipe 5 .

[0015] The refrigerant collecting box 3 is connected to a refrigerant output pipe 6 .

[0016] An extrusion-type ice-making evaporator with high heat exchange efficiency is disclosed. By changing the structure of the evaporator, the refrigerant enters the refrigerant diverter box 2 through the refrigerant input pipe 5. After the refrigerant is filled, the refrigerant contacts the cylinder 1 through a plurality of evaporator tubes 4 through the diversion effect of the refrigerant diverter box 2, and each evaporator tube 5 only surrounds the cylinder 1 once. After absorbing heat, the refrigerant enters the refrigerant focusing box 3 and is then discharged through the refrigerant output pipe 6. Compared with the prior art, the movement path of the refrigerant after absorbing heat in the pipeline becomes shorter and can be discharged in time, thereby greatly improving the heat exchange efficiency.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
