[0027] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0028] like Figure 1 The figure is a schematic diagram of an embodiment of a phase change heat storage tank provided by the utility model.
[0029] Please refer to Figure 1 This embodiment is used for waste heat recovery and reuse, and has the function of stabilizing the refrigeration efficiency of the refrigeration chip. It is specifically used in beverage equipment to cool and heat beverage liquids.
[0030] This embodiment specifically includes an insulating tank body 10, a refrigeration chip 11, a heat conduction component 12, a phase change heat storage body 13 and a pipeline 14. A refrigeration chip 11 is provided on the surface of the insulating tank body 10, the cold end of the refrigeration chip 11 (the left side in the figure) is located outside the insulating tank body 10, and the hot end of the refrigeration chip 11 (the right side in the figure) is located inside the insulating tank body 10. The hot end of the refrigeration chip 11 is connected to the heat conduction component 12, and the heat conduction component 12 conducts heat to the pipeline 14 through the phase change heat storage body 13. The inlet and outlet of the pipeline 14 are located outside the insulating tank body 10.
[0031] The insulated tank body 10 has an opening on the side, and the shape and size of the opening match the refrigeration chip 11. The insulated tank body 10 is made of an insulating material, or is coated with an insulating layer on the outside. The refrigeration chip 11 is embedded in the opening. The refrigeration chip 11 is specifically a semiconductor refrigeration chip. After power is turned on, the cold end cools and the hot end releases heat. The cold energy generated by the cold end of the refrigeration chip 11 can be used by beverage equipment to cool beverages. The heat generated by the hot end is absorbed by the phase change heat storage body 13. The phase change heat storage body 13 undergoes a phase change after absorbing the heat. Since the temperature does not change during the phase change process, the temperature of the hot end does not change, thereby avoiding the refrigeration efficiency of the refrigeration chip 11 from being reduced due to the excessively high temperature of the hot end, and maintaining a stable refrigeration efficiency.
[0032] In one embodiment, the heat conducting component 12 includes a heat pipe 121 and a heat conducting plate 122. The heat pipe 121 and the heat conducting plate 122 are arranged inside the heat insulating tank 10, the head end of the heat pipe 121 is in contact with the hot end of the refrigeration chip 11, and the middle and tail ends of the heat pipe 121 are in contact with the heat conducting plate 122. The heat conducting component 12 is used to transfer the heat released from the hot end of the refrigeration chip 11 to the phase change heat storage body 13.
[0033] Furthermore, the phase-change heat storage body 13 is arranged inside the heat-insulating tank body 10, and the phase-change heat storage body 13 covers the middle part and the tail end of the heat pipe 121, and the phase-change heat storage body 13 covers the heat-conducting plate 122, and the length of the heat-conducting plate 122 is adapted to the height of the phase-change heat storage body 13, and the width of the heat-conducting plate 122 is adapted to the inner diameter of the heat-insulating tank body 10. The heat-insulating tank body 10 is a cylinder, the heat pipe 121 is used for longitudinal heat conduction, and the heat-conducting plate 122 is used for transverse heat conduction, and both play the role of increasing the contact area with the phase-change heat storage body 13.
[0034] Specifically, the head end and the middle part of the heat pipe 121 are connected by a bending part, and the bending part is bent toward the inside of the heat-insulating tank body 10, so that the middle part and the tail end of the heat pipe 121 are away from the inner surface of the heat-insulating tank body 10. The heat pipe 121 is bent toward the inside of the heat-insulating tank body 10, close to the inside of the heat-insulating tank body 10, so that the heat absorbed by the heat pipe 121 is diffused outward from the inside of the phase-change thermal storage body 13, the heat transfer efficiency is higher, and the heat loss is reduced.
[0035] In one embodiment, the inlet and outlet of the pipeline 14 are connected through a curved pipeline or a bent pipeline, the curved pipeline or the bent pipeline is located inside the heat-insulating tank 10, and the phase-change thermal storage body 13 covers the curved pipeline or the bent pipeline. The pipeline 14 can be a spiral pipeline or a serpentine pipeline. The use of such a pipeline 14 increases the path length of the pipeline, thereby increasing the time for the liquid in the pipeline 14 to flow through, so that the liquid and the phase-change thermal storage body 13 can fully exchange heat.
[0036] In one embodiment, the upper side of the heat-insulating tank 10 is a cavity, and the lower side accommodates the phase-change thermal storage body 13, which is a solid-liquid phase-change thermal storage body. The cavity with a certain space reserved on the upper side of the heat-insulating tank 10 is adapted to the volume change of the phase-change thermal storage body 13 during phase change. The solid-liquid phase-change thermal storage body has the advantages of small volume change during phase change, large volumetric heat storage density, and small temperature fluctuation.
[0037] The phase change heat storage body 13 is an organic phase change material, and the melting point temperature of the phase change heat storage body 13 is 40-45 degrees Celsius. The phase change heat storage body 13 in this embodiment can specifically be made of animal fat combined with additives.
[0038] like Figure 2 As shown, the utility model also provides an embodiment of a beverage device.
[0039] Please refer to Figure 2 This embodiment includes the above-mentioned phase change heat storage tank embodiment, and also includes a heating component 2, a water storage tank 3 and a brewing component 4.
[0040] The water storage tank 3 is connected to the inlet of the pipeline 14 of the phase change thermal storage tank 1 through the pump 5. The phase change thermal storage tank 1 preheats the water transported by the water storage tank 3. The outlet of the pipeline 14 of the phase change thermal storage tank 1 is connected to the heating component 2. The heating component 2 reheats the water transported by the phase change thermal storage tank and outputs the heated water to the brewing component 4. The water enters the brewing component 4 and is brewed before being output. The brewed beverage can be output into the container through the valve switch.
[0041] The focus of this embodiment is on the connection relationship of each component. The heating component 2 can be a heating tube with resistance heating, and the brewing component 4 can be a brewer for brewing coffee. The specific structures of the heating component 2, the brewing component 4 and other components are all conventional design structures. The heating component 2 can realize the heating function, the water storage tank 3 can realize the water storage function, the pump 5 can realize the pressurization function, and the brewing component 4 can realize the brewing function. The specific structures are not repeated here.
[0042] like Figure 3 As shown, the utility model also provides an embodiment of a brewing system.
[0043] Please refer to Figure 3This embodiment adds a cold drink container 6 and a hot drink container 7 on the basis of the above beverage equipment embodiment. The cold drink container 6 and the hot drink container 7 can be cups and other containers. The cold drink container 6 and the hot drink container 7 are respectively connected to the brewing component 4 in the beverage equipment, and the brewing component 4 outputs the brewed beverage to the cold drink container 6 or the hot drink container 7 respectively. The cold drink container 6 is connected to the cold end of the refrigeration chip 11 in the phase change thermal storage tank 1 through the heat conduction cavity 8. The heat conduction cavity 8 surrounds the circumference of the cold drink container 6 and is used to conduct the coldness of the refrigeration chip 11. The heat conduction cavity 8 can be made of stainless steel.
[0044] Furthermore, the cold drink container 6 receives the hot water output by the brewing component 4, and the cold energy generated by the cold end of the refrigeration chip 11 in the phase change heat storage tank 1 is transferred to the cold drink container 6 through the heat conduction cavity 8, so as to refrigerate the beverage in the cold drink container 6 and realize the production of cold drinks.
[0045] During the process of making the chip 11, the phase change heat storage body 13 in the phase change heat storage tank 1 generates phase change to store the heat generated by the refrigeration chip 11. The heat stored in the phase change heat storage body 13 is transferred to the pipeline 14 in the phase change heat storage body 13, preheating the water in the pipeline 14 and releasing the stored heat. The preheated water is transported to the heating component 2 for heating and then transported to the brewing component 4, and the brewing component 4 outputs the brewed beverage to the hot beverage container 7 or the cold beverage container 6.
[0046] In the above embodiments, the circuit connection methods and control methods involved are of conventional design and are not the focus of the implementation of the embodiment scheme, so they will not be described in detail.
[0047] In summary, in the embodiment provided by the utility model, the cold end of the refrigeration chip is located outside the heat-insulating tank body, which is convenient for the use of cold energy, and the hot end is located inside the heat-insulating tank body. The heat generated by the hot end is transferred to the phase-change thermal storage body through the heat-conducting component. The phase-change thermal storage body absorbs heat to produce phase change, so that the temperature of the hot end remains unchanged and does not continue to rise, thereby achieving stable and efficient operation of the refrigeration chip. In addition, the phase-change thermal storage body transfers heat to the pipeline, heats the liquid in the pipeline, and realizes the reuse of waste heat.
[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
