Abstract
Description
Technical Field
[0001] This invention relates to the field of beverage processing equipment technology, and more particularly to a non-dilution temperature control device for fluids. Background Technology
[0002] In the fields of specialty coffee and high-end wines, achieving "non-dilution, instantaneous, and deep" temperature control of fluids has always been an industry challenge. Existing cooling solutions have the following significant drawbacks:
[0003] 1. Flavor dilution and loss: Ice dilution changes the fluid concentration; refrigeration takes too long, resulting in a large loss of aroma substances produced at high temperatures.
[0004] 2. Low-flow icing and blockage (a pain point in cold starts):
[0005] In the initial stage of pour-over coffee brewing, such as during the blooming process, the extremely low flow rate of high-temperature fluid will instantly undergo a phase change and freeze upon encountering an extremely low-temperature cold source, leading to physical blockage of the flow channel.
[0006] 3. The contradiction between heat exchange efficiency and flow channel crossflow: Due to the simple flow channel design, the fluid in the existing cooling equipment is very prone to axial "crossflow (direct fall)" under the action of gravity; and the smooth surface is prone to the formation of laminar sublayer, which has extremely high thermal resistance.
[0007] 4. Asymmetric freezing deformation damage gap:
[0008] The energy storage medium expands in volume when it freezes. If the equipment is placed horizontally or tilted arbitrarily in the freezer, the air bag will be misaligned and generate asymmetrical compressive force, causing the metal wall to bend or become out of round at the micrometer level, directly damaging the fitting clearance and making the equipment impossible to assemble.
[0009] 5. Air resistance overflow and liquid discharge surge (gurgling effect): When heat exchange is carried out in a narrow gap, air trapped in the water will cause overflow; and when the core is poured out, due to the lack of internal air compensation, intermittent surges will occur, resulting in unstable water output.
[0010] 6. Hygiene challenges: Traditional heat exchangers have a closed structure, making them difficult to clean.
[0011] Therefore, a non-dilution temperature control device for fluids is designed to provide an alternative technical solution to the above-mentioned technical problems. Summary of the Invention
[0012] Therefore, it is necessary to provide a non-dilution temperature control device for fluids to address the above-mentioned technical problems, thereby solving the technical problem that existing temperature control devices are prone to slight deformation due to heat exchange during use, which makes them impossible to assemble or detach, and at the same time, they cannot control the temperature in non-dilution conditions.
[0013] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0014] A non-dilution temperature control device for fluids, comprising:
[0015] A first thermal management component, and a second thermal management component detachably nested within the first thermal management component;
[0016] The first thermal management component and / or the second thermal management component have a cavity inside for accommodating the energy storage medium;
[0017] The outer surface of the second thermal management component is provided with a recessed nonlinear flow groove.
[0018] As a preferred embodiment of the non-dilution temperature control device for fluids provided by the present invention, the inner wall of the first thermal management component is provided with at least one axially extending groove.
[0019] As a preferred embodiment of the non-dilution temperature control device for fluids provided by the present invention, the cavity of the second thermal management component is provided with an internal heat transfer enhancement structure.
[0020] The internal heat transfer enhancement structure is at least one of phase change heat transfer element and high thermal conductivity solid component;
[0021] The internal heat transfer enhancement structure is constructed as a three-dimensional heat conduction network within the cavity. At least a portion of the structure in the three-dimensional heat conduction network is thermally coupled to the inner wall surface of the second thermal management component and extends radially into the cavity and / or axially to both ends.
[0022] In a preferred embodiment of the non-dilution temperature control device for fluid provided by the present invention, the top of the second thermal management component is provided with a liquid collection tank, the top of the nonlinear flow channel is connected to the liquid collection tank, and the bottom of the second thermal management component is provided with heat dissipation fins.
[0023] In a preferred embodiment of the non-dilution temperature control device for fluids provided by the present invention, the bottom of the second thermal management component is provided with a drainage channel that communicates with the nonlinear flow channel.
[0024] In a preferred embodiment of the non-dilution temperature control device for fluids provided by the present invention, the nonlinear flow channel is a first annular flow channel.
[0025] In a preferred embodiment of the non-dilution temperature control device for fluids provided by the present invention, the first annular flow channel is a U-shaped channel.
[0026] In a preferred embodiment of the non-dilution temperature control device for fluid provided by the present invention, the first annular flow channel is composed of stepped channels and smooth surfaces, and adjacent stepped channels are connected by smooth surfaces.
[0027] As a preferred embodiment of the non-dilution temperature control device for fluid provided by the present invention, the top surface of the smooth surface is provided with a plurality of micro-grooves extending along the fluid travel direction, and the cross-section of the micro-grooves is sawtooth-shaped or wavy.
[0028] A method for continuous fluid temperature control based on the device of claim 1 includes the following steps:
[0029] The device is configured to enable continuous temperature control via multiple interchangeable second thermal management components;
[0030] The first thermal management component is equipped with an active cooling element or a passive thermal insulation structure to continuously maintain the low temperature boundary state inside it, so as to serve as a heat exchange base station.
[0031] Each of the second thermal management components is filled with a phase change energy storage medium and pre-cooled to a predetermined state; multiple second thermal management components are detachably nested with the first thermal management component in a cyclical and replaceable manner. After the second thermal management component that has completed heat exchange is removed, it is replaced with another second thermal management component in a pre-cooled state to achieve uninterrupted continuous temperature regulation and output of fluid.
[0032] A method for instantaneous large gradient temperature difference conversion of fluid based on the device of claim 1 includes the following steps:
[0033] The device is configured to achieve instantaneous large gradient temperature difference conversion within a single fluid passage cycle by physically coupling dynamic falling film heat exchange with static immersion heat exchange.
[0034] The liquid collection tank at the top of the second thermal management component temporarily stores a small flow rate of fluid during the initial fluid injection phase, thereby releasing sensible heat and preheating the heat exchange interface to prevent blockage by transient solid phase crystallization.
[0035] The fluid is forced to generate periodic hydraulic jumps and eddies by passing through a stepped drop structure on the bottom surface of the nonlinear flow channel to strip away the thermal resistance boundary layer; and the liquid film is anchored and the dynamic heat transfer area is increased by micro-grooves extending along the direction of fluid travel on the bottom surface of the channel, thus completing the first stage of cooling of the fluid.
[0036] The fluid cooled in the first stage is collected inside the expansion chamber at the bottom of the first thermal management component, and then subjected to a second stage of static immersion heat exchange through the heat dissipation fins that extend into the expansion chamber at the bottom of the second thermal management component.
[0037] A gas-liquid self-balancing control method based on the device of claim 1 includes the following steps:
[0038] A gas-liquid control channel, independent of the main heat exchange gap, is formed through the grooves on the inner wall of the first thermal management component.
[0039] When the device is in the vertical liquid injection state, there is at least one groove. The groove is used as an exhaust path to discharge the compressed gas in the liquid collection chamber at the bottom of the device, so as to eliminate the air back pressure in the main heat exchange gap and prevent fluid overflow.
[0040] When the device is in the tilted drainage state, there are at least two grooves that are symmetrically distributed. The groove located below serves as a fluid outflow channel, and the groove located above serves as an external air inflow channel. Through the physical isolation and synchronous replacement of the gas phase and liquid phase in different grooves, the gas resistance surge effect during the drainage process is eliminated, and a stable and linear fluid output is achieved.
[0041] It is clear without a doubt that the technical problems to be solved by the present invention can be solved by the above-described technical solutions of the present invention.
[0042] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:
[0043] The present invention provides a non-dilution temperature control device for fluids. Through the cooperation of an outer barrel, an inner core, and a closed ring, when the inner core is installed inside the outer barrel, the refrigerant or heat medium placed inside the first cavity and the second cavity can regulate the temperature of the fluid entering the first and second annular flow grooves on the inner core under non-dilution conditions. Furthermore, the gap between the outer side of the inner core and the inner side of the outer barrel prevents slight deformation caused by heat exchange from preventing the fluid from being disassembled or assembled.
[0044] Through the cooperation of the outer tub, the closing ring and the support plate, the top of the first cavity inside the outer tub can be closed or opened by the closing ring, so that the refrigerant or heat medium can be put into the first cavity. At the same time, the support plate supports the position of the first cavity at the bottom of the outer tub.
[0045] Through the cooperation of the first core, the second core and the heat dissipation fins, the second core can be connected to the top of the first core as a whole, so that the fluid inside the liquid collection tank can enter the interior of the second annular flow channel through the liquid inlet channel, and then enter the interior of the first annular flow channel. Finally, the temperature is adjusted at the bottom of the outer barrel, located on the outside of the heat dissipation fins.
[0046] By using different shapes of the first annular flow channel, different temperature control requirements can be met, thereby expanding the application scenarios of the temperature control device of the present invention.
[0047] Through multifunctional support components, the conflicting technical challenges of "anti-condensation sealing" and "smooth pressure relief and flow" in heat exchanger design are resolved collaboratively. This achieves a perfect closed loop of heat source isolation, steam dissipation, anti-condensation, and directional exhaust and pressure relief through purely mechanical / material deformation, without adding external moving parts or control circuits. Combined with a nano-hydrophobic coating on the heat exchange surface, condensate contamination in cryogenic equipment under high temperature and humidity environments is completely eliminated, ensuring the absolute purity of the flavor of fluids such as specialty coffee.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0062] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0063] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0064] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0065] Example 1
[0066] Reference Figures 1-5 A non-dilution temperature control device for fluids, comprising:
[0067] The first thermal management component has a first cavity 4 inside for containing an energy storage medium, for placing a refrigerant or a heat medium, thereby cooling or heating the fluid through heat exchange and other processes; and the inner wall of the first thermal management component has at least one axially extending groove 6.
[0068] In this embodiment, the first thermal management component is the outer barrel 1, which is used for external support and protection.
[0069] In this embodiment, the outer barrel 1 is supported by a straight cylindrical shape and an outward convex shape, with a ratio of 2:1 between the straight cylindrical shape and the outward convex shape. This allows the heat dissipation fins 12 at the bottom of the inner core 2 to be located in the outward convex position, enabling the fluid to flow and be regulated on the outside of the heat dissipation fins 12.
[0070] In this embodiment, foaming strips may also be evenly distributed inside the first cavity 4.
[0071] Preferably, a support plate 5 is fixed at the bottom of the first cavity 4 to provide fixed support between the inner and outer layers of the outer barrel 1 separated by the first cavity 4. At the same time, the diameter of the support plate 5 is one-third of the bottom diameter of the first cavity 4, so as not to affect the adjustment of the refrigerant or heat medium at the bottom of the first cavity 4.
[0072] In this embodiment, at least two grooves 6 are symmetrically distributed along the circumference at 180 degrees. They are used to serve as fluid outflow channels and air inflow channels when the liquid is poured at an angle (most of the time the inner core 2 is removed before pouring, but the inner core 2 can also be used for pouring). This achieves physical separation of gas and liquid in the core-containing state, completely eliminating the "surge" and splashing phenomenon during liquid pouring, ensuring linear and stable water flow. At the same time, during vertical liquid injection, they serve as pressure relief channels to discharge internal air, eliminate back pressure and prevent overflow. In other embodiments, the number of grooves 6 can be one or more.
[0073] The second thermal management component is detachably nested within the first thermal management component, and the interior of the second thermal management component has a second cavity for accommodating the energy storage medium;
[0074] In this embodiment, the second thermal management component is the inner core 2, which is detachably installed on the inside of the outer barrel 1.
[0075] In this embodiment, the outer barrel 1 and the inner core 2 can both be cylindrical, or they can be frustum-shaped with an inclined shape, etc.
[0076] In this embodiment, both the first thermal management component and the second thermal management component are filled with an energy storage medium to form a double-sided heat exchange; in one embodiment, only the second thermal management component is filled with an energy storage medium, and the first thermal management component serves as a heat-insulating flow guiding container; in another embodiment, only the first thermal management component is filled with an energy storage medium, and the second thermal management component serves as a heat-insulating flow guiding container.
[0077] Preferably, the outer surface of the second thermal management component is provided with a recessed nonlinear flow groove to force the fluid to flow along a predetermined trajectory and prolong the contact time.
[0078] Preferably, the top of the second thermal management component is provided with a liquid collection tank 9, the top of the nonlinear flow channel is connected to the liquid collection tank 9, and the bottom of the second thermal management component is provided with heat dissipation fins 12 for adjusting the height of the bottom of the second thermal management component inside the outer barrel 1, and when the fluid is located outside the heat dissipation fins 12 inside the first thermal management component, the heat exchange temperature is improved by the heat dissipation fins 12.
[0079] In this embodiment, the liquid collection tank 9 has a heat buffer function, which is used to temporarily store a small flow of fluid during the blooming stage of hand-drip coffee, and use its sensible heat to preheat the top of the inner core to prevent icing and blockage during cold start.
[0080] Preferably, the heat dissipation fins 12 are made of a material that can conduct cold or heat, such as copper or food-grade stainless steel.
[0081] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.
[0082] Example 2
[0083] refer to Figure 5 and Figure 6 Based on the above embodiment one, the following is disclosed:
[0084] Core 2 includes:
[0085] The bottom of the first core 7 is fixed to the heat dissipation fins 12, so that the first core 7 and the heat dissipation fins 12 can be adjusted as a whole.
[0086] The nonlinear flow channel includes a first annular flow channel 10 and a second annular flow channel 11;
[0087] The outer side of the first core 7 is spirally provided with a first annular flow groove 10, which can increase the contact time on the outer side of the first core 7 through the flow of fluid inside the first annular flow groove 10, and then cool the fluid through the refrigerant inside the second cavity 20; the bottom of the first annular flow groove 10 is provided with a drain channel 13, which allows the fluid inside the first annular flow groove 10 to be discharged through the drain channel 13 to the outer side of the inner core 2 located on the heat dissipation fins 12.
[0088] Preferably, the first core 7 has a second cavity 20 inside, and the bottom of the second cavity 20 extends into the center of the heat dissipation fin 12, so that a refrigerant or heat medium can be placed inside the heat dissipation fin 12, thereby facilitating non-contact temperature control of the fluid.
[0089] Preferably, a first magnetic component is fixed to the bottom of the inner side of the outer barrel 1, and a second magnetic component is fixed to the bottom of the heat dissipation fins 12. The magnetic repulsion between the first and second magnetic components prevents the bottom of the inner core 2 from directly hitting the bottom of the inner barrel 1 during assembly, thus preventing dents or damage. Both the first and second magnetic components are high-temperature resistant strong magnets.
[0090] The second core 8 is located on top of the first core 7, so that the assembly of the second core 8 and the first core 7 forms the inner core 2, which is convenient for integral installation inside the outer barrel 1. The top of the second core 8 has a liquid collection tank 9 for storing the fluid that needs temperature control and for intercepting the fluid. The outer side of the second core 8 has a second annular flow channel 11, which is connected to the liquid collection tank 9. This allows the bottom outlet of the second annular flow channel 11 to connect with the top inlet of the first annular flow channel 10 when the second core 8 is assembled on top of the first core 7, so that the fluid inside the liquid collection tank 9 can enter the first annular flow channel 10 through the second annular flow channel 11. The liquid collection tank 9 has an inlet channel 19 located inside the second annular flow channel 11, which is connected to the liquid collection tank 9, so that the fluid inside the liquid collection tank 9 can enter the second annular flow channel 11 through the inlet channel 19.
[0091] In other embodiments, an internal heat transfer enhancement structure may also be provided inside the cavity of the inner core 2;
[0092] The internal heat transfer enhancement structure is at least one of phase change heat transfer element and high thermal conductivity solid component, wherein the phase change heat transfer element is one of heat pipe, heat spreader, inward star-shaped heat dissipation fins, etc.
[0093] The internal heat transfer enhancement structure is constructed as a three-dimensional heat conduction network within the cavity. At least a portion of the structure in the three-dimensional heat conduction network is thermally coupled to the inner wall surface of the second thermal management component (inner core 2) and extends radially into the cavity and / or axially to both ends.
[0094] In this embodiment, the interior of both the first annular flow groove 10 and the second annular flow groove 11 can be coated with a food-grade nano oleophobic / hydrophobic layer. Combined with the flow direction design, it can achieve "one-rinse cleaning". A sealing ring can be added at the connection position between the first core 7 and the second core 8 to prevent refrigerant leakage. The overall height ratio of the first core 7 and the second core 8 to the height of the heat dissipation fins 12 is 2:1, which allows the fluid to flow inside the first annular flow groove 10 of the first core 7 for a longer time.
[0095] In this embodiment, the second core 8 is installed on top of the first core 7 by a threaded connection. In other embodiments, it can also be connected by snap-fit, transition fit, or other means.
[0096] Preferably, baffles 14 are fixed inside the first core 7 and outside the first annular flow groove 10, and inside the second core 8 and outside the second annular flow groove 11, so that the fluid can be prevented from overflowing to the outer wall of the inner core 2 when flowing inside the first annular flow groove 10 or the second annular flow groove 11.
[0097] The process of using a non-dilution temperature control device for fluids provided by the present invention is as follows: When in use, for cooling, the refrigerant is placed inside the second cavity 20, and then the second core 8 is assembled on top of the first core 7 to form the inner core 2;
[0098] The refrigerant is placed inside the first cavity 4;
[0099] Then the inner core 2 is placed inside the outer barrel 1. Due to the gap between the outer side of the inner core 2 and the inner side of the outer barrel 1, the inner core 2 will not be unable to be assembled or detached inside the outer barrel 1 when it deforms and expands.
[0100] At this time, the fluid that needs to be temperature-controlled is poured into the inside of the liquid collection tank 9, allowing the fluid inside the liquid collection tank 9 to flow into the inside of the second annular flow tank 11 through the liquid inlet channel 19, and then into the inside of the first annular flow tank 10 through the inside of the second annular flow tank 11. At the same time, the baffle 14 blocks the outside to prevent overflow. When the fluid flows inside the first annular flow tank 10, the refrigerant inside the second cavity 20 cools the fluid, while the refrigerant inside the first cavity 4 cools and regulates the temperature of the inside of the outer tank 1, thus achieving dual temperature control.
[0101] When the fluid inside the first annular flow channel 10 flows out through the drain channel 13 to the outside of the heat dissipation fins 12 located inside the outer barrel 1, the refrigerant inside the second cavity 20 is conducted through the heat dissipation fins 12, and at the same time the fluid outside the heat dissipation fins 12 is cooled by the refrigerant at the bottom of the first cavity 4, achieving double cooling. After the cooling time is reached, the inner core 2 is taken out through the groove 6, the inner core 2 is separated from the outer barrel 1, and the fluid inside the outer barrel 1 is poured out, thus achieving cooling.
[0102] When heating is required, simply replace the refrigerant with a heat transfer medium.
[0103] Example 3
[0104] Based on the above embodiments one and two, the following additional features are also included:
[0105] The closing ring 3 is installed on the outside of the inner core 2 at the top of the first cavity 4 to close the top of the first cavity 4. A sealing ring can be added at the connection between the closing ring 3 and the first cavity 4 to prevent refrigerant leakage.
[0106] Preferably, the inner part of the top of the closed ring 3 is evenly distributed with adjustment grooves, which facilitates the rotation of the closed ring 3 through the adjustment grooves, so as to realize the assembly or disassembly of the closed ring 3 at the top of the first cavity 4. Anti-slip textures can also be fixed on the outer side of the closed ring 3 to increase friction and drive the closed ring 3 to rotate.
[0107] In this embodiment, the closed ring 3 is connected to the first cavity 4 on the outer barrel 1 by a threaded connection. In other embodiments, they can also be connected by snap-fit, transition fit, or other methods.
[0108] Example 4
[0109] refer to Figure 7 Based on the above embodiment 2, the first annular flow channel 10 is a U-shaped channel 15, which allows fluid to flow through the shape of the U-shaped channel 15 inside the first core 7 and the second core 8.
[0110] Example 5
[0111] refer to Figures 8-9 Based on the above embodiment 2, the first annular flow channel 10 is composed of stepped channels 16 and flat surfaces 17. Two adjacent stepped channels 16 are connected by flat surfaces 17, so that the stepped channels 16 are composed of multiple step shapes and are smoothed by the connected flat surfaces 17. When the fluid flows, it flows through the stepped channels 16 and then smooths at the top of the flat surfaces 17 to increase the flow time and achieve the effect of increasing the heat exchange area.
[0112] Example 6
[0113] refer to Figures 10-11 Based on the above embodiment five, micro-grooves 18 are evenly distributed on the top of the flat surface 17, so that the micro-grooves 18 are opened in the direction of water flow on the top of the flat surface 17, thereby increasing the heat exchange area.
[0114] In other embodiments, the cross-section of the microgroove 18 is serrated or wavy.
[0115] Example 7
[0116] Apply the temperature control device of this invention to a home setting;
[0117] You can purchase only one outer barrel 1 and one inner core 2;
[0118] In Embodiment 1, water or other refrigerant is placed inside the second cavity 20 of the inner core 2. The second core 8 is assembled on top of the first core 7 to form the inner core 2. Water or other refrigerant is placed inside the first cavity 4. The closed ring 3 is installed on top of the first cavity 4 to form the outer barrel 1. The outer barrel 1 and the inner core 2 are then placed in a refrigerator to freeze. When needed, they are taken directly out of the refrigerator. The inner core 2 is then installed inside the outer barrel 1, allowing the fluid to cool down in the inner core 2.
[0119] Example 8
[0120] Apply the temperature control device of this invention to commercial scenarios;
[0121] One outer barrel 1 and several inner cores 2 can be purchased;
[0122] Water or other refrigerant can be placed inside the second cavity 20 of the inner core 2 in Embodiment 1, and the second core 8 can be assembled on top of the first core 7 to form the inner core 2.
[0123] A semiconductor cooling chip is installed at the bottom of the first cavity 4. At the same time, the support column installed at the bottom of the outer barrel 1 allows the cold side of the semiconductor cooling chip to be located inside the first cavity 4, while the hot side of the semiconductor cooling chip is allowed to contact the outside air through the bottom of the outer barrel 1, thereby achieving air cooling.
[0124] When in use, the frozen inner core 2 is taken out of the freezing equipment and placed inside the outer barrel 1. The outer barrel 1 is cooled by the cold surface of the semiconductor cooling chip on the outer barrel 1, which in turn cools the fluid flowing on the inner core 2.
[0125] Example 9
[0126] Unlike Embodiment 1, the outer barrel 1 and the inner core 2 can also be joined together by two flat plates (or more plates) on the left and right sides, and a zigzag or reciprocating flow channel can be carved out on the joined plane.
[0127] Example 10
[0128] Based on the above embodiments one to nine, the following is disclosed:
[0129] The top of the first thermal management component (outer tank 1) is equipped with a multi-functional support member (filter cup holder). This member is constructed as a composite structure that integrates physical load-bearing, thermal insulation, steam dissipation, anti-condensation microenvironment construction, and directional pressure relief functions.
[0130] Multifunctional support components include:
[0131] Discontinuous support section: The top surface of this component has a cross-shaped, star-shaped or multi-point protrusion structure, which is used to form point contact or line contact support with external heat sources (such as filter cups). In this way, the direct heat conduction from the 90°C external heat source to the cryogenic thermal management component is minimized through the discontinuous support structure at the top. At the same time, the physical contact area of the external heat source cuts off the direct heat bridge to the first thermal management component. The open space formed between the support points allows the hot steam generated by the high-temperature fluid to dissipate upwards and prevents water vapor backflow.
[0132] Flexible sealing ring: A food-grade flexible sealing ring (such as a silicone gasket) is fixed on the bottom surface of this component (i.e., the contact surface that mates with the top opening of the first thermal management component). Thus, when the support component is closed on top of the first thermal management component, the flexible sealing ring at the bottom blocks the top opening of the annular flow channel from the external environment. Because the internal cold air sinks, external humid and hot air cannot penetrate, thus forming a relatively sealed, anti-condensation microenvironment above the fluid channel. This prevents external water vapor from condensing and frosting on the cryogenic surface, ensuring zero loss of fluid concentration.
[0133] Directional exhaust structure: A directional exhaust structure is provided on the multifunctional support member and / or flexible sealing ring, precisely aligned spatially with the longitudinal groove 6 corresponding to the inner wall of the first thermal management component; eliminating air back pressure in the sealed state:
[0134] Implementation Plan A (Exhaust Gap):
[0135] The directional venting structure consists of a localized venting notch created on the flexible sealing ring. During vertical liquid injection, the air discharged from the liquid collection chamber escapes outward along the longitudinal groove 6 through this notch, eliminating air resistance.
[0136] Implementation Plan B (One-way exhaust valve):
[0137] The directional venting structure consists of a one-way venting valve (such as a silicone duckbill valve or umbrella valve) located at the edge of the supporting component. When fluid injection generates a slight positive pressure, the one-way valve automatically opens to vent outwards; in the non-injection state, the one-way valve automatically closes due to its self-elasticity, completely preventing backflow of external air.
[0138] Results Achieved: Through multifunctional support components, the conflicting technical challenges of "anti-condensation sealing" and "smooth pressure relief and flow" in heat exchanger design were resolved collaboratively. This resulted in a perfect closed loop of heat source isolation, steam dissipation, anti-condensation, and directional exhaust pressure relief achieved through purely mechanical / material deformation, without adding external moving parts or control circuits. Combined with a nano-hydrophobic coating on the heat exchange surface, condensate contamination in cryogenic equipment under high temperature and humidity environments was completely eliminated, ensuring the absolute purity of the flavor of fluids such as specialty coffee.

[0140] Based on the above embodiments one to six, a non-dilution temperature control method for fluids is disclosed, comprising the following steps:
[0141] S1: The refrigerant is placed inside the first cavity 4, and the closed ring 3 is assembled on the top of the first cavity 4 to form the outer barrel 1, so as to start cooling the cavity inside the outer barrel 1.
[0142] S2: The refrigerant is placed inside the second cavity 20, and the second core 8 is assembled on top of the first core 7 to form the inner core 2;
[0143] S3: Place the inner core 2 inside the outer barrel 1. After the inner core 2 enters the cooled cavity inside the outer barrel 1, it is cooled again by the refrigerant inside the second cavity 20. The fluid is injected into the liquid collection tank 9 and the fluid flows from the second annular flow channel 11 to the inside of the first annular flow channel 10 for the first cooling.
[0144] S4: When the fluid inside the first annular flow channel 10 flows into the outside of the heat dissipation fins 12 inside the outer barrel 1 through the drain channel 13, it achieves secondary cooling by exchanging heat with the refrigerant and heat dissipation fins 12 at the bottom of the first cavity 4, thus completing non-contact cooling of the fluid.
[0145] When the fluid is heated, the refrigerant inside the first cavity 4 in step S1 and the refrigerant inside the second cavity 20 in step S2 are replaced with a heat transfer medium to achieve heat conduction.

[0147] Based on the above embodiment one, the disclosed device provides a method for continuous fluid temperature control, comprising the following steps:
[0148] The device is configured to enable continuous temperature control via multiple interchangeable second thermal management components;
[0149] The first thermal management component (outer barrel 1) is equipped with an active cooling element (such as a semiconductor cooling chip) or a passive thermal insulation structure to continuously maintain the low temperature boundary state inside it as a heat exchange base station.
[0150] Each second thermal management component (inner core 2) is filled with a phase change energy storage medium and pre-cooled to a predetermined state; multiple second thermal management components are detachably nested with the first thermal management component in a cyclical and replaceable manner. After the second thermal management component that has completed heat exchange is removed, it is replaced with another second thermal management component in a pre-cooled state to achieve uninterrupted continuous temperature regulation and output of fluid.

[0152] Based on the above embodiment one, the disclosed device provides a method for instantaneous large gradient temperature difference conversion of fluid, used in a nested device of a first thermal management component (outer barrel 1) and a second thermal management component (inner core 2), with the following steps:
[0153] The device is configured to achieve instantaneous large gradient temperature difference conversion within a single fluid passage cycle by physically coupling dynamic falling film heat exchange with static immersion heat exchange.
[0154] The liquid collection tank 9 at the top of the second thermal management component temporarily stores a small flow of fluid during the initial fluid injection phase, so as to release the sensible heat preheating heat exchange interface and prevent transient solid phase crystallization blockage.
[0155] The fluid is forced to generate periodic hydraulic jumps and eddies through the stepped drop structure on the bottom surface of the nonlinear flow channel to strip away the thermal resistance boundary layer; and the liquid film is anchored and the dynamic heat exchange area is increased through the micro-grooves 18 extending along the direction of fluid travel on the bottom surface of the path, thus completing the first stage of cooling of the fluid.
[0156] The fluid cooled in the first stage is collected inside the expansion chamber at the bottom of the first thermal management component, and then subjected to a second stage of static immersion heat exchange through the heat dissipation fins 12 that extend into the expansion chamber at the bottom of the second thermal management component.
[0157] Example 14
[0158] Based on the above embodiment one, the gas-liquid self-balancing control method of the disclosed device has the following steps:
[0159] A gas-liquid guiding channel, independent of the main heat exchange gap, is formed through the groove 6 on the inner wall of the first thermal management component.
[0160] When the device is in the vertical liquid injection state, there is at least one groove 6. The groove 6 is used as an exhaust path to discharge the compressed gas in the liquid collection chamber at the bottom of the device, so as to eliminate the air back pressure in the main heat exchange gap and prevent fluid overflow.
[0161] When the device is in the tilted discharge state, there are at least two grooves 6 that are symmetrically distributed. The lower groove 6 serves as a fluid outflow channel, and the upper groove 6 serves as an external air inflow channel. Through the physical isolation and synchronous replacement of the gas phase and liquid phase in different grooves 6, the gas resistance surge effect during the discharge process is eliminated, and the smooth and linear output of the fluid is achieved.
