Description

Technical Field

[0001] This utility model relates to the field of mold temperature controller technology, specifically to a high-efficiency cooling device for mold temperature controllers. Background Technology

[0002] In the application of mold temperature controllers, their cooling effect plays a crucial role in the operational stability of the entire system and product quality. Currently, most mold temperature controllers on the market use plate heat exchangers or single-channel copper tube coolers, which often result in extremely high outlet water temperatures due to insufficient inlet water flow. Increasing the heat exchange area to improve cooling efficiency leads to excessively large cooler volumes. Therefore, this application proposes a high-efficiency cooling device for mold temperature controllers. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling device for a mold temperature controller, comprising a housing, a heat medium inlet pipe provided at the top of one side of the housing, a heat medium outlet pipe provided at the bottom of the other side of the housing, and a first cooling copper pipe and a second cooling copper pipe provided inside the housing;

[0005] Both the first cooling copper tube and the second cooling copper tube are spiral tubular structures wound from top to bottom. The inner diameter of the spiral tube wound by the first cooling copper tube is larger than the outer diameter of the spiral tube wound by the second cooling copper tube.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency cooling device for a mold temperature controller, comprising a housing 10, a heat medium inlet pipe 11 at the top of one side of the housing 10, and a heat medium outlet pipe 12 at the bottom of the other side of the housing 10. Inside the housing 10 are a first cooling copper pipe 30 and a second cooling copper pipe 40. Both the first cooling copper pipe 30 and the second cooling copper pipe 40 are spiral tubular structures wound from top to bottom. The inner diameter of the spiral tube wound by the first cooling copper pipe 30 is larger than the outer diameter of the spiral tube wound by the second cooling copper pipe 40. The second cooling copper pipe 40 is inserted inside the first cooling copper pipe 30. In practical application, the heat medium enters the device from the heat medium inlet pipe 11 at the top of one side of the housing 10, first contacting the flow channel formed on the outside of the first cooling copper pipe 30. Because the first cooling copper pipe 30 is a spiral tubular structure... In this structure, as the heat medium flows from top to bottom, it undergoes thorough heat exchange with the cooling medium inside the first cooling copper pipe 30. Simultaneously, some of the heat medium enters the flow channel formed between the first cooling copper pipe 30 and the second cooling copper pipe 40, continuing to flow downwards. During this process, it again exchanges heat with the cooling medium inside the second cooling copper pipe 40. Finally, the remaining heat medium enters the flow channel formed inside the second cooling copper pipe 40, where it exchanges heat with the cooling medium again until it is discharged from the heat medium discharge pipe 12 at the bottom of the other side of the shell 10. By increasing the heat exchange area and water inflow within the same volume, high-efficiency heat exchange is achieved, and the outlet water temperature is reduced. At the same time, the structure is compact, and the increased heat exchange area does not lead to an excessively large cooler volume, thus solving the problems of low cooling efficiency and large size of existing coolers.

[0024] The bottom of the housing 10 is provided with a bottom cover plate 13, and a drain pipe 14 is inserted into the center of the bottom cover plate 13. A control valve is provided on the drain pipe 14. After the device has been used for a period of time, the impurities and dirt that may be generated inside the device can be cleaned. By opening the control valve on the drain pipe 14, the impurities and dirt can be discharged to ensure the normal operation and cooling effect of the device.

[0025] The first cooling copper pipe 30 has a first cooling medium inlet 31 at one end and a first cooling medium outlet 32 ​​at the other end; the second cooling copper pipe 40 has a second cooling medium inlet 41 at one end and a second cooling medium outlet 42 at the other end. In actual operation, the cooling medium enters the first cooling copper pipe 30 from the first cooling medium inlet 31, exchanges heat with the heat medium during its flow in the first cooling copper pipe 30, absorbs heat, and then flows out from the first cooling medium outlet 32. Similarly, another cooling medium enters the second cooling copper pipe 40 from the second cooling medium inlet 41, exchanges heat with the heat medium during its flow in the second cooling copper pipe 40, absorbs heat, and then flows out from the second cooling medium outlet 42. This design allows the cooling medium to circulate fully and continuously remove the heat from the heat medium.

[0026] The casing 10 has a top cover plate 20, on which a first cooling medium inlet connector 21, a first cooling medium outlet connector 22, a second cooling medium inlet connector 23, and a second cooling medium outlet connector 24 are sequentially mounted. The first cooling medium inlet end 31 is connected to the first cooling medium inlet connector 21, and the first cooling medium outlet end 32 is connected to the first cooling medium outlet connector 22. The second cooling medium inlet end 41 is connected to the second cooling medium inlet connector 23, and the second cooling medium outlet end 42 is connected to the second cooling medium outlet connector 24. The cooling medium can enter the first cooling copper pipe 30 and the second cooling copper pipe 40 from the first cooling medium inlet connector 21 and the second cooling medium inlet connector 23 respectively. During its flow within the pipes, it exchanges heat with the heat medium and then flows out from the first cooling medium outlet connector 22 and the second cooling medium outlet connector 24 respectively, forming independent cooling medium circulation paths to ensure stable and efficient cooling. Furthermore, the tight interconnections between the components reduce the risk of cooling medium leakage.

[0027] The design incorporates flow channels for the heating medium, forming channels on the outer side of the first cooling copper pipe 30, between the first and second cooling copper pipes 30 and 40, and inside the second cooling copper pipe 40. In the channel on the outer side of the first cooling copper pipe 30, the heating medium initially exchanges heat with the cooling medium inside the first cooling copper pipe 30. When the heating medium enters the channel between the first and second cooling copper pipes 30 and 40, it further exchanges heat with the cooling medium inside the second cooling copper pipe 40. Finally, in the channel inside the second cooling copper pipe 40, the heating medium exchanges heat with the cooling medium again. Through these three heat exchange processes, a significant amount of heat is carried away from the heating medium, resulting in a significant reduction in the outlet water temperature. Simultaneously, this multi-channel design greatly increases the heat exchange area within a limited space, improving cooling efficiency.

[0028] Working principle: When in use, first connect the device to the mold temperature controller system through the heat medium inlet pipe 11 and heat medium outlet pipe 12 on the housing 10. At the same time, connect the first cooling medium inlet connector 21 and the second cooling medium inlet connector 23 to the cooling medium supply pipeline respectively, and connect the first cooling medium outlet connector 22 and the second cooling medium outlet connector 24 to the cooling medium return pipeline respectively.

[0029] When the mold temperature controller is running, the heat medium enters the housing 10 through the heat medium inlet pipe 11, and flows sequentially through the flow channel outside the first cooling copper pipe 30, the flow channel between the first cooling copper pipe 30 and the second cooling copper pipe 40, and the flow channel inside the second cooling copper pipe 40. At the same time, the cooling medium enters the first cooling copper pipe 30 and the second cooling copper pipe 40 through the first cooling medium inlet connector 21 and the second cooling medium inlet connector 23, respectively. During the flow process in the pipe, it fully exchanges heat with the heat medium, absorbs the heat of the heat medium, and then flows out from the first cooling medium outlet connector 22 and the second cooling medium outlet connector 24, respectively, returning to the cooling medium supply system for cooling and recycling. After the heat medium temperature is greatly reduced after multi-stage heat exchange, it is finally discharged from the heat medium outlet pipe 12 and returns to the mold temperature controller system to continue to participate in the circulation. In the whole working process, the device achieves efficient heat exchange in a limited space through a unique spiral tubular structure design and multi-channel layout, effectively solving the problems of low cooling efficiency and large size of existing coolers.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
