Description

Technical Field

[0002] The current fin evaporator adopts a single inlet and single outlet structural design, and the inlet end is connected to a capillary tube that acts as a throttling and controls the refrigerant flow rate. When the evaporator is in a refrigeration cycle, it cools with a fixed refrigerant flow rate, and the energy consumption of the refrigerator is relatively fixed. However, as the energy-saving standards for refrigerators become more and more stringent, it is difficult to meet the standards by only using traditional methods such as variable frequency compressors. It is impossible to meet the refrigeration cycle requirements in different usage scenarios and achieve the goal of more energy saving at the same time. Therefore, a fin evaporator with variable flow refrigeration is designed to solve the problem of high energy consumption caused by the inability to adjust the flow standard of the fin evaporator capillary. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 4 As shown, the utility model provides the following technical solutions: a fin evaporator with variable flow refrigeration includes a fin evaporator 7, a water inlet pipe 1, a capillary tube and a connecting structure, the connecting structure includes a diverter 2, the water inlet pipe 1 is fixedly connected to the fin evaporator 7, and the end of the water inlet pipe 1 is connected to the diverter 2, the capillary tube and the water inlet pipe 1 are fixedly connected through the diverter 2, the connecting structure is used to control the flow size of the water inlet pipe 1, the connecting structure also includes a connecting pipe 3 and an extension pipe 5, the end of the water inlet pipe 1 is connected to the connecting pipe 3, the side of the surface of the connecting pipe 3 away from the fin evaporator 7 is fixedly connected to the extension pipe 5, the diverter 2 is installed on the extension pipe 5, the port of the diverter 2 is threadedly connected to a transfer tube 4, the capillary tube and the diverter 2 are fixedly connected through the transfer tube 4, the end of the transfer tube 4 is sleeved with a rubber ring 10, and the two ends of the side wall of the rubber ring 10 are in contact with the diverter 2 and the connecting pipe 3 respectively.

[0020] Through the above technical scheme: during installation, the adapter tube 4 is first fixed to the port of the diverter 2 by means of a spiral connection. At this time, the two sides of the rubber ring 10 are in contact with the diverter 2 and the adapter tube 4 respectively, thereby filling the gap between the diverter 2 and the adapter tube 4, improving the sealing and reducing the occurrence of leakage. Subsequently, capillaries of different diameters are installed one by one on the adapter tube 4, and then installed on the diverter 2 through the adapter tube 4. Multiple capillaries of different diameters are fixedly installed on the same water inlet pipe 1 by using the connecting pipe 3, the diverter 2 and the adapter tube 4. During operation, the control system is used to detect and adjust the opening and closing of different ports on the diverter 2, so that a single or multiple capillaries can participate in the refrigeration cycle at the same time, thereby solving the problem of high energy consumption due to the inability to adjust the flow standard of the capillary of the fin evaporator 7.

[0021] See also Figure 1-Figure 4 As shown, the inner diameter of the rubber ring 10 is smaller than the diameter of the transfer tube 4, a groove is provided at the end of the transfer tube 4 and on the side away from the diverter 2, the inner wall of the rubber ring 10 is embedded in the groove, a through hole 11 is provided on one side of the surface of the rubber ring 10, a connecting buckle 8 is installed on one side of the outer wall of the diverter 2, a connecting rope 9 is wound and fixed on the connecting buckle 8 and the through hole 11, and the connecting rope 9 is used to control the distance between the connecting buckle 8 and the rubber ring 10, the length of the connecting tube 3 is smaller than the width of the fin evaporator 7, and the connecting tube 3 is vertically arranged beside the fin evaporator 7, a support plate 6 is provided on one side of the outer wall of the fin evaporator 7, a groove is provided on the surface of the support plate 6, and the end of the connecting tube 3 is embedded in the groove.

[0022] Through the above technical solution: since the rubber ring 10 is clamped on the transfer tube 4 through the groove, the rubber ring 10 will not directly detach from the transfer tube 4 during the normal taking and moving process. Therefore, when replacing different transfer tubes 4, since the rubber ring 10 and the connecting buckle 8 are fixedly connected by the connecting rope 9, and the rubber ring 10 cannot independently detach from the transfer tube 4 without being affected by external force, after the transfer tube 4 is detached from the diverter 2, it still cannot directly detach from the diverter 2. While eliminating the need to find the step to facilitate the replacement of the transfer tube 4, the problem of losing the transfer tube 4 is also reduced. In addition, the installed support plate 6 can be used to support the connecting tube 3, thereby reducing the bending of the water inlet pipe 1 due to excessive liquid mass.
