[0025] Next, in conjunction with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0026] As Figure 1 shown, the embodiment of the present invention provides a vortex tube 4 cold and hot integrated box, which includes a box body 1. The box body 1 includes a heating layer 2 and a refrigerating layer 3. A first heat exchange device 21 is provided in the heating layer 2, and a second heat exchange device 31 is provided in the refrigerating layer 3. At least one vortex tube 4 is provided on the box body 1. The hot end outlet of the vortex tube 4 is connected to the first heat exchange device 21, and the cold end outlet of the vortex tube 4 is connected to the second heat exchange device 31. An exhaust hot gas pipe 8 and an exhaust cold gas pipe 9 are provided on the box body 1. The exhaust hot gas pipe 8 is connected to the heating layer 2, and the exhaust cold gas pipe 9 is connected to the refrigerating layer 3.
[0027] Among them, a nozzle, a vortex generator and a hot end regulating valve are provided in the vortex tube 4. The nozzle is used to introduce high-pressure gas from the inlet of the vortex tube 4 into the inner cavity of the vortex tube 4. The vortex generator is located behind the nozzle and is used to make the high-pressure gas perform a rotational motion to form a vortex effect, thereby separating the high-pressure gas into a hot end air flow and a cold end air flow. The hot end regulating valve is located at the hot end outlet of the vortex tube 4 and is used to adjust the amount of high-temperature gas at the hot end outlet, so as to control the ratio between the low-temperature gas and the high-temperature gas in the vortex tube 4, and further control the refrigeration effect in the refrigerating layer 3.
[0028] Water storage layers are provided in both the refrigerating layer 3 and the heating layer 2, and a liquid is stored in the water storage layer. The liquid in the water storage layer provided in the heating layer 2 is used to absorb and transfer the heat of the high-temperature gas generated by the vortex tube 4 to heat the items stored in the heating layer 2. The liquid in the water storage layer provided in the refrigerating layer 3 is used to absorb and transfer the cold of the low-temperature gas generated by the vortex tube 4 to refrigerate the items stored in the refrigerating layer 3.
[0029] Specifically, in this embodiment, the box body 1 is made of explosion-proof steel plates or lightweight aluminum materials. A sandwich layer is provided between the inner and outer walls of the box body, and polyurethane foam is used as the sandwich material, which can block the heat conduction path to achieve a good heat preservation effect. The first heat exchange device 21 and the second heat exchange device 31 are made of aluminum alloy materials. The heating layer 2 is made of high-temperature and corrosion-resistant stainless steel. The refrigeration layer 3 is made of ABS plastic, which has good impact resistance, heat resistance and chemical resistance, helps to isolate external heat, keep the internal temperature stable, reduce energy consumption and improve refrigeration efficiency.
[0030] As Figure 2 , Figure 3 shown, the first heat exchange device 21 is located at the bottom of the heating layer 2 and immersed in the water storage layer, and is used to transfer heat to heat the liquid in the water storage layer.
[0031] The first heat exchange device 21 includes two first header pipes 211, a plurality of first louver fins 213 and a plurality of first porous flat tubes 212. The first header pipes 211 are communicated with the first porous flat tubes 212. The two first header pipes 211 are placed along the left and right side walls of the box body 1, and the plurality of first porous flat tubes 212 are placed along the front and rear side walls of the box body 1. The first louver fins 213 are located between two adjacent first porous flat tubes 212, and the first louver fins 213 and the first porous flat tubes 212 are arranged in an interlaced manner.
[0032] Among them, the first header pipes 211 are used to receive the high-temperature gas from the hot end of the vortex tube 4 and evenly distribute it to the plurality of first porous flat tubes 212. This layout helps to make the most of the entire space of the heating layer 2, enabling the hot air flow to cover every corner of the box body, thus achieving a more uniform heating effect. The first porous flat tubes 212 are communicated with the first header pipes 211. The design of these flat tubes not only enables them to provide a larger heat exchange area in a limited space, but also can effectively disperse the hot air flow through their porous structure, further enhancing the heat transfer efficiency. The porous design inside the flat tubes can also promote gas flow, so that the heat will not concentrate in a certain place during the transfer process, but can be evenly diffused to each area within the heating layer 2. The design of the louver fins can not only increase the heat dissipation area of the heat exchanger, but also guide the air flow through the gaps between the fins, thereby further improving the heat exchange efficiency. The interlaced layout helps to form a turbulent flow, breaking the laminar state of the air flow, so that the heat can be transferred from the gas to the fins and the heating layer 2 more efficiently.
[0033] A first partition plate 214 is provided in the first header pipe 211 on one side close to the vortex tube 4. The first partition plate 214 divides the first header pipe 211 into a first flow channel 2111 and a second flow channel 2112. The first flow channel 2111 is communicated with the hot end outlet of the vortex tube 4 and is used to receive the high-temperature gas separated from the vortex tube 4. The second flow channel 2112 is communicated with the waste hot gas discharge pipe 8, so that after the first heat exchange device 21 completes heat exchange, the remaining waste heat gas can be discharged, ensuring the smooth flow of the gas in the first heat exchange device 21. By providing the first partition plate 214, the first flow channel 2111 and the second flow channel 2112 are respectively responsible for the management of gases at different temperatures, enabling the hot gas and the waste gas to be treated independently and avoiding the phenomenon of mixed flow. At the same time, the effective discharge of the waste gas prevents the accumulation of heat, ensuring the overall stability and safety of the system.
[0034] As Figure 4 , Figure 5 shown, the second heat exchange device 31 is arranged in an L shape. Through this layout method, the cold air can be more evenly distributed in the refrigerating layer 3, thereby achieving a more comprehensive cooling effect.
[0035] The second heat exchange device 31 includes two second header pipes 311, a plurality of second louver fins 313 and a plurality of second porous flat tubes 312. One of the second header pipes 311 is arranged in the horizontal direction along the left and right side walls of the box body 1, and the other second header pipe 311 is arranged in the vertical direction along the front and rear side walls of the box body 1. The second porous flat tubes 312 are communicated with the second header pipes 311. The second louver fins 313 are located between two adjacent second porous flat tubes 312, and the second louver fins 313 and the second porous flat tubes 312 are arranged in an alternating manner. In this embodiment, the first louver fins 213 and the second louver fins 313 are corrugated louver fins.
[0036] A second partition plate 314 is provided in the second header pipe 311 on one side close to the vortex tube 4. The second partition plate 314 divides the second header pipe 311 into a third flow channel 3111 and a fourth flow channel 3112. The third flow channel 3111 is communicated with the cold end outlet of the vortex tube 4 to receive the low-temperature gas discharged from the cold end of the vortex tube 4. The cold air enters the second porous flat tubes 312 through the third flow channel 3111 for heat exchange, thereby transferring the cold quantity into the refrigerating layer 3. The fourth flow channel 3112 is communicated with the waste cold air discharge pipe 9, so that after the second heat exchange device 31 completes heat exchange, the waste cold air is discharged.
[0037] As Figure 1As shown, a control assembly 5 is provided on the vortex tube 4. The control assembly 5 includes a switching valve 52 and a pressure regulating and reducing valve 51. The switching valve 52 is used to control the input of high-pressure gas, and the pressure regulating and reducing valve 51 is used to regulate and stabilize the pressure of the high-pressure gas input into the vortex tube 4. The switching valve 52 is connected to the pressure regulating and reducing valve 51, and the pressure regulating and reducing valve 51 is connected to the vortex tube 4.
[0038] Adopting the above solution: When the system needs to start working, the switching valve 52 is opened to allow high-pressure gas to enter the pressure regulating and reducing valve 51. The pressure regulating and reducing valve 51 regulates the input high-pressure gas to ensure that the gas pressure is stabilized within the range required for the operation of the vortex tube 4. The regulated gas flows into the vortex tube 4, and the system starts the refrigeration or heating operation.
[0039] A pressure relief valve 6 is provided at the top of the box body 1. The pressure relief valve 6 is used to prevent the internal pressure of the box from being too high. Among them, the pressure relief valve 6 is set at the top of the box body, which is convenient for quickly discharging gas and preventing gas from staying in the box. When the internal pressure of the box exceeds the safety limit, it automatically releases the excess gas to reduce the internal pressure, thereby preventing equipment damage or safety hazards that may be caused by excessive pressure.
[0040] At least one punching plate 7 is provided in both the heating layer 2 and the refrigerating layer 3. The punching plate 7 is fixedly connected to the box body 1 and is respectively installed above the first heat exchange device 21 and the second heat exchange device 31 for placing food. Among them, the punching plate 7 installed in the heating layer 2 can ensure that heat is evenly transferred to the internal area of the box through the liquid medium, making the temperature in the heating layer 2 more uniform; the punching plate 7 installed in the refrigerating layer 3 can ensure that cold is evenly transferred to the internal area of the box through the liquid medium, taking away the excess heat and keeping the temperature inside the refrigerating layer 3 always at a low temperature state.
[0041] The box body 1 is provided with a first sealing door 10 and a second sealing door 10. The first sealing door 10 and the second sealing door 10 are both hinged to the box body 1. The first sealing door 10 and the second sealing door 10 are respectively arranged corresponding to the heating layer 2 and the refrigerating layer 3, and are used to prevent the cold air in the refrigerating layer 3 or the heat in the heating layer 2 from leaking.
[0042] A plurality of moving members 11 are provided at the bottom of the box body 1. The moving members are used to move and fix the position of the box body 1. Preferably, in this embodiment, the moving members 11 are self-locking universal wheels.
[0043] It should be understood that in the present utility model, terms such as "first" and "second" are used to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present utility model, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0044] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
