Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, specifically to a heat exchange auxiliary structure for an energy-saving refrigeration system for display cabinets. Background Technology

[0002] Display cases are indispensable equipment in supermarket operations. Using open or glass-door structures, they allow customers to directly observe refrigerated goods, directly increasing sales. A stable refrigeration system maintains a constant low temperature inside the case, extending the shelf life of products and ensuring food quality. Beverage display cases require long-term continuous operation and have a high energy consumption ratio. Therefore, they typically use energy-efficient refrigeration systems, which can significantly reduce operating energy consumption and costs, reduce environmental heat load, and optimize the shopping experience.

[0003] In existing technologies, the evaporators in the refrigeration systems of beverage display cases are mostly coil-type, which have limited heat exchange efficiency. In other finned evaporators, the fins for auxiliary heat exchange are generally straight or corrugated, which are all fixed structures. However, beverage display cases have high customer traffic and more frequent door openings during the day, resulting in a high heat load inside the case. At night, customer traffic is low, and the heat load inside the case is low. The fixed structure of the straight fins cannot adjust the auxiliary heat exchange intensity according to the fluctuation of the heat load of the display case. Under high load, it is easy to have insufficient heat exchange, resulting in slow cooling. Under low load, it is easy to have excessive heat exchange, resulting in waste of cooling capacity, increasing the operating load of the refrigeration equipment, high energy consumption, and reduced equipment lifespan.

[0004] Therefore, we propose an auxiliary structure for heat exchange in an energy-saving refrigeration system for display cabinets to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary heat exchange structure for an energy-saving refrigeration system for display cabinets, in order to solve the problems mentioned in the background art, such as the different heat load inside the beverage display cabinet during the day and night, the inability of the fixed structure of the straight fins to adjust the auxiliary heat exchange intensity according to the heat load fluctuation of the display cabinet, the easy insufficient heat exchange leading to slow cooling under high load, and the easy excessive heat exchange leading to waste of cooling capacity under low load, thus increasing the operating load of the equipment and high energy consumption.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When this invention is used, the first and second retracting mechanisms are driven to move synchronously by the power mechanism, so as to realize the reversible deformation of the elastic rhomboid fins and the adjustment of the fin cavity state. Under high load conditions, the cavity is filled with a wide state and thermally conductive silicone oil to form a double reinforcement; under low load conditions, the cavity is filled with a narrow state and a hollow cavity to form a double optimization. The coordinated control can cope with different heat load conditions, assist in adjusting the heat exchange intensity, avoid increasing the operating load of the equipment, and further improve the energy saving effect.

[0017] 2. When using this invention, the segmented structure design of the pull-out frame and pull-out ring allows the power mechanism to uniformly control the width and narrow deformation of the fins and the flow and filling of the thermally conductive silicone oil. No additional power device is required, achieving passive synergy and forming a synergistic link of power, deformation, fluid, and heat conduction. This enables precise control of high-load strong heat exchange and low-load low energy consumption, resulting in a significant improvement in energy efficiency compared to traditional static fins.

[0018] 3. When using this invention, the elastic rhomboid fins are set with rounded corners and micro-arc shapes. Through the streamlined structure, combined with the fin width deformation and fluid heat conduction, the three are deeply coupled to form a synergistic adaptive heat exchange system.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-12 As shown, the present invention provides a technical solution: A heat exchange auxiliary structure for an energy-saving refrigeration system of a display cabinet includes an evaporator body 1 and a mounting shell 2 installed on the top and bottom of the evaporator body 1. It also includes a power mechanism 3 and several deformable fins 4. Each deformable fin 4 is provided with several first retraction mechanisms 5 and several second retraction mechanisms 6. The first retraction mechanisms 5 are used to drive some of the fins in the deformable fin 4 to dynamically deform. The second retraction mechanisms 6 are used to squeeze the thermally conductive silicone oil to fill the interior of the deformable fin 4. The power mechanism 3 is used to drive the first retracting mechanism 5 and the second retracting mechanism 6 to move simultaneously; The deformable fin 4 includes an elastic rhomboid fin 401 and a fixed fin 402. Several elastic bladders 408 are fixedly connected to the four sides inside the elastic rhomboid fin 401, and each elastic bladder 408 is filled with thermally conductive silicone oil. Under the compression of the second pulling mechanism 6, the elastic bladder 408 forces the thermally conductive silicone oil to flow into the cavity of the elastic rhomboid fin 401 to enhance the thermal conductivity of the elastic rhomboid fin 401. Each first retracting mechanism 5 includes a retracting frame 501, a reinforcing rod 503, a double limiting rod 504, a double ring rod 505, a connecting rod 506, and a fixed seat 507. There are two reinforcing rods 503, double limiting rods 504, and double ring rods 505. Rollers 511 are movably sleeved at both ends of the two double limiting rods 504.

[0023] There are four fixed seats 507 and four connecting rods 506. The outer surfaces of the four connecting rods 506 are respectively movably embedded in the interior of two double ring rods 505. The outer surface of each fixed seat 507 is movably fitted with a rotating seat 508. The outer surface of each rotating seat 508 is fixedly installed with two telescopic rods 509. The two ends of each connecting rod 506 are fixedly installed with a limiting plate 510. One side of the outer surface of the limiting plate 510 is fixedly connected to one end of the telescopic rod 509.

[0024] One end of each of the two reinforcing rods 503 is fixedly connected to the outer surface of the two double limiting rods 504, and the other end of each of the two reinforcing rods 503 is fixedly connected to the outer surface of the two double ring rods 505. The outer surfaces of the four rollers 511 are in contact with the two sides inside the retractable frame 501. Movable holes 502 are provided on the outer surfaces of both sides of the retractable frame 501. The outer surfaces of the two reinforcing rods 503 are movably embedded in the two movable holes 502. The four fixed seats 507 are fixedly installed on the four sides inside the elastic rhomboid fin 401.

[0025] In practical applications, when the beverage display case is under high load and the internal heat load is high, the control system drives the power mechanism 3 to start, driving the first retracting mechanism 5 and the second retracting mechanism 6 to move simultaneously. The first retracting mechanism 5 releases the tension on both sides of the elastic diamond-shaped fins 401. At this time, the elastic diamond-shaped fins 401 rebound due to their own elasticity, and their sides expand outward, deforming into a wide state, such as... Figure 12 As shown in the left-hand diagram, the second retracting mechanism 6 then compresses the elastic bladder 408, forcing the thermally conductive silicone oil within it to flow through the oblique hole 407 into the thermally conductive cavity 406, filling the cavity of the elastic diamond-shaped fin 401. At this time, the states of the first retracting mechanism 5 and the second retracting mechanism 6 are as follows: Figure 5 As shown, the multiple deformable fins 4 on the outer surface of the evaporator body 1 are all wide-shaped, such as... Figure 1 and Figure 3 As shown, when the elastic diamond-shaped fin 401 is in its wide state, the windward area is maximized, increasing the heat exchange contact on the air side and providing a structural basis for strong heat exchange. At the same time, the cavity of the elastic diamond-shaped fin 401 is filled with high thermal conductivity silicone oil. The large windward area in the wide state and the high thermal conductivity of the thermally conductive silicone oil form a double reinforcement, which quickly absorbs the heat of the hot air inside the cabinet and achieves rapid cooling inside the display cabinet.

[0026] When the beverage display case is operating at low load at night and the heat load inside the case is low, the control system drives the cylinder 301 (using Airtac MI16×20S-CA model) to retract, which drives the fixing bar 302 and fixing rod 303 to move downward. The second retraction mechanism 6 first releases the pressure on the elastic bladder 408, and the thermally conductive silicone oil automatically flows back from the thermally conductive cavity 406 to the elastic bladder 408. At this time, the fin cavity returns to a hollow state, which can reduce unnecessary loss of cold energy from the fins and avoid waste of cold energy. Simultaneously, the retractable frame 501 moves downward (the width of the fixed rod 303 within the retractable frame 501 is relatively small, not affecting the rolling of the subsequent rollers 511), and the rollers 511 roll along its three-section inner wall. When the rollers 511 roll to the middle arc section, they are pushed by the arc wall, causing the two rollers 511 to move relative to each other while rolling. The reinforcing rod 503 pulls the double-ring rods 505 on both sides to move relative to each other. The double-ring rods 505, through the reinforcing rod 503, exert tension on both sides of the elastic diamond-shaped fins 401, causing them to deform from a wide state to a narrow state, such as... Figure 12 As shown in the right-hand diagram, the double-ring rod 505 is slidably connected to the connecting rod 506. The telescopic rods 509 and the rotating seat 508 at both ends of the connecting rod 506 are movably connected to the fixed seat 507. These components slide and rotate in accordance with the deformation of the elastic rhomboid fins 401 without affecting the deformation of the rhomboid fins 401. When the rhomboid fins are in a narrow state, the windward area is reduced. The small windward area in the narrow state, combined with the low thermal conductivity of the hollow cavity, creates a dual optimization, minimizing the operating load of the fan while ensuring stable temperature inside the cabinet, thus achieving energy-saving operation. By coordinating the first retracting mechanism 5 and the second retracting mechanism 6, the shape changes of the elastic rhomboid fins 401 are used to cope with different heat load conditions, assist in adjusting the heat exchange intensity, avoid equipment operating load, and further improve energy-saving effect. This solves the problem that the heat load inside the beverage display cabinet is different during the day and night, and the flat fins with fixed structure cannot adjust the auxiliary heat exchange intensity according to the heat load fluctuation of the display cabinet. Under high load, it is easy to have insufficient heat exchange, resulting in slow cooling, and under low load, it is easy to have excessive heat exchange, resulting in waste of cold energy, increasing equipment operating load and high energy consumption.

[0027] See Figure 4 and Figures 9-11 As shown, the interior of the elastic rhomboid fin 401 is provided with several heat-conducting cavities 406. The inner wall of each heat-conducting cavity 406 is provided with several oblique holes 407. The elastic bladder 408 is connected to the heat-conducting cavity 406 through the oblique holes 407. Several elastic ribs 404 are fixedly installed at the two corners inside the elastic rhomboid fin 401. The interior of each elastic rib 404 is provided with a flow cavity 409. The outer surface of the elastic rhomboid fin 401 is provided with several flow holes 405. Each flow cavity 409 is connected to two adjacent flow holes 405.

[0028] It should also be noted that when the elastic diamond-shaped fin 401 is in the wide state, the elastic bladder 408 is compressed, and the thermally conductive silicone oil filled inside is forced to flow into the thermally conductive cavity 406 through the oblique hole 407. This allows the thermally conductive silicone oil to be evenly injected into the four fins of the elastic diamond-shaped fin 401, forming a continuous and efficient heat conduction path. The overall temperature of the fin is more uniform, and the effective heat exchange area is greatly improved. When the elastic diamond-shaped fin 401 is in the narrow state, the elastic bladder 408 loses the compressive force, and the thermally conductive silicone oil automatically flows back into the elastic bladder 408, which can reduce unnecessary loss of cold energy from the fin and avoid waste of cold energy.

[0029] Furthermore, the elastic ribs 404 have an included angle of 60° and are evenly distributed inside the elastic rhomboid fins 401. This not only enhances the overall structural strength of the elastic rhomboid fins 401, but also, in conjunction with the flow holes 405, forms a through-flow channel, allowing some air to pass directly through the elastic rhomboid fins 401 instead of merely skimming along the surface. This significantly reduces the air-side thermal boundary layer and improves the heat transfer coefficient. The elastic ribs 404 have good elasticity and can expand and contract synchronously with the deformation of the elastic rhomboid fins 401, ensuring that the channel remains unobstructed at all times.

[0030] See Figures 3-4 , Figure 9 and Figure 11 As shown, the fixed fin 402 is fixedly connected to the coil of the evaporator body 1, and the front surface of the fixed fin 402 is fixedly connected to the elastic diamond fin 401. The fixed fin 402 is used to transfer the cooling capacity of the coil of the evaporator body 1 to the elastic diamond fin 401. The top and bottom of the elastic diamond fin 401 are fixedly connected with elastic gaskets 403. The two sharp corners on both sides of the outer surface of the elastic diamond fin 401 are rounded. The four outer sides of the elastic diamond fin 401 are all slightly arc-shaped.

[0031] It should also be noted that the deformable fins 4 are fixedly connected to the coils of the evaporator body 1 via the fixed fins 402, ensuring that there are no gaps or contact thermal resistance at the connection surface, and guaranteeing that the cooling capacity of the evaporator coils can be efficiently transferred to the elastic diamond-shaped fins 401. The elastic gasket 403 itself has good elasticity and can deform with the elastic diamond-shaped fins 401 without affecting the shape change of the elastic diamond-shaped fins 401.

[0032] Furthermore, the two sharp corners of the elastic rhomboid fin 401 are rounded, and all four outer surfaces are slightly arc-shaped, such as 8 and Figure 11 As shown, the radius of the rounded corner is controlled between 0.5-1.0 mm, preferably 0.8 mm. The surface of the fin is polished to reduce surface roughness, so that the airflow can flow smoothly along the micro-arc surface.

[0033] See Figures 5-6 and Figure 8As shown, each second retracting mechanism 6 includes a connecting plate 601, a retracting ring 602, a support base 608, and a pressing plate 604. There are two retracting rings 602 and two support bases 608. The top ends of the two retracting rings 602 are respectively fixedly installed on the outer surfaces of the two sides of the connecting plate 601. Two retaining rings 603 are movably sleeved on the outer surfaces of the two retracting rings 602.

[0034] It should also be noted that the downward movement of the fixing rod 303 causes the connecting plate 601 and the two pull rings 602 to move downward together. The arc-shaped inclined rods on both sides exert a pushing force on the retaining rings 603, causing the two retaining rings 603 to move relative to each other in turn, thereby causing the corresponding pressing plates 604 to move relative to each other, realizing the closing of the four pressing plates 604, releasing the compression on the elastic bladder 408, and allowing the thermally conductive silicone oil to automatically flow back.

[0035] See Figure 5 and Figure 8 As shown, there are four compression plates 604. The opposite side of the four compression plates 604 is fixedly connected to four retaining rings 603, and the other side of each compression plate 604 squeezes four elastic bladders 408. Two springs 605 are fixedly connected between each pair of laterally adjacent compression plates 604.

[0036] It should also be noted that when the pressure plate 604 closes, it will compress the spring 605 to make it contract. When the pull ring 602 moves upward, the force on the retaining ring 603 disappears, and the spring 605 uses its own elasticity to push the pressure plate 604 to expand, and compress the elastic bladder 408 again, so that the thermally conductive silicone oil flows into the blade cavity.

[0037] See Figure 8 and Figure 11 As shown, one side of the outer surface of each of the two support seats 608 is fixedly installed on the outer surface of the fixed fin 402. T-shaped strips 606 are fixedly installed on the top and bottom of the four pressure plates 604. A T-shaped slide rod 607 is fixedly installed at one end of each T-shaped strip 606. Two T-shaped slide grooves 609 are opened on the opposite side of each of the two support seats 608. Each pair of T-shaped slide rods 607 distributed laterally forms a group. One end of each group of T-shaped slide rods 607 moves inside the T-shaped slide groove 609.

[0038] It should also be noted that the support base 608 provides auxiliary support for the pressure plate 604. When the pressure plate 604 closes or expands, it drives the corresponding T-shaped slide rod 607 to slide in the T-shaped slide groove 609, which limits the pressure plate 604 and improves its movement stability.

[0039] See Figures 3-6As shown, the power mechanism 3 includes a cylinder 301, several fixing bars 302, a fixing rod 303, and a fixing plate 304. The bottom of the fixing bar 302 is fixedly connected to the output end of the cylinder 301, and the top of the fixing bar 302 is fixedly connected to the bottom end of several fixing bars 302. The top end of the fixing rod 303 is fixedly inserted through one of the elastic pads 403 and extends into the interior of the elastic rhomboid fin 401. The pull-out bracket 501 and the connecting plate 601 are both fixedly installed on the outer surface of the fixing rod 303. The top of the two support seats 608 are both provided with sliding holes 610, and the outer surface of the fixing rod 303 is movably embedded in the interior of the sliding holes 610.

[0040] It should also be noted that the movement of the output end of the cylinder 301 drives the fixed bar 302 and the fixed rod 303 to move up and down, thereby driving the retracting frame 501 and the connecting plate 601, which are fixedly connected to the fixed rod 303, to move simultaneously, so as to realize the simultaneous movement of the first retracting mechanism 5 and the second retracting mechanism 6, thereby realizing the shape change of the elastic rhomboid fin 401 and the change of the fin cavity state.

[0041] See Figures 3-4 and Figures 6-7 As shown, the retractable bracket 501 has a three-section structure, consisting of a lower straight section, a middle arc section, and an upper straight section. The retractable ring 602 has a two-section structure, consisting of a lower arc section and an upper straight section. The bottom end of the fixing rod 303 extends movably into the interior of one of the mounting housings 2. The fixing strip 302 is located inside one of the mounting housings 2. The fixing plate 304 is fixedly installed inside one of the mounting housings 2, and the cylinder 301 is installed on the top of the fixing plate 304. Multiple telescopic support rods 305 are fixedly installed on the top of the fixing plate 304, and the top ends of the telescopic support rods 305 are fixedly connected to the bottom of the fixing strip 302.

[0042] It should also be noted that the structures of the retractable bracket 501 and the retractable ring 602 are as follows: Figure 6As shown, the lower straight section of the retractable frame 501 corresponds to the lower inclined arc of the retractable ring 602, and the middle arc of the retractable frame 501 corresponds to the upper straight section of the retractable ring 602. When the fixed rod 303 drives the retractable frame 501 and the retractable ring 602 to move downward synchronously (deform into a narrow state), the roller 511 moves at the lower straight section of the retractable frame 501. At this time, it is not subjected to thrust, and the elastic diamond-shaped fin 401 does not deform. However, the retaining ring 603 is subjected to thrust at the lower inclined arc of the retractable ring 602, which drives the pressure plate 604 to close. The elastic bladder 408 loses its compression and automatically rebounds. When the retaining ring 603 is located at the upper straight section of the retractable ring 602, the roller 511 moves to the middle arc of the retractable frame 501. The roller 511 is simultaneously subjected to thrust, which drives the elastic diamond-shaped fin 401 to deform into a narrow state. When the fixed rod 303 drives the retracting bracket 501 and the retracting ring 602 to move upward synchronously (deform to the wide state), the elastic rhomboid fins 401 first return to the wide state, and then the pressure plate 604 squeezes the elastic bladder 408. The width and narrow deformation of the elastic rhomboid fins 401 and the flow and filling of the thermally conductive silicone oil are uniformly controlled by the power mechanism 3. No additional power device is required, and the passive coordination achieves precise control of high load strong heat exchange and low load low energy consumption.

[0043] Please see Figures 1-12 As shown, the overall effect and working principle of the mechanism are as follows: When the beverage display cabinet is under high load and the heat load inside the cabinet is high, the control system controls the power mechanism 3 to start, driving the first retracting mechanism 5 and the second retracting mechanism 6 to move simultaneously. The first retracting mechanism 5 releases the tension on both sides of the elastic diamond-shaped fins 401. At this time, the elastic diamond-shaped fins 401 rely on their own elastic rebound deformation to a wide state, maximizing the windward area and increasing the air-side heat exchange contact, providing a structural basis for strong heat exchange. Then, the second retracting mechanism 6 squeezes the elastic bladder 408, forcing the thermally conductive silicone oil to flow through the inclined hole 407 into the heat-conducting cavity 406. The two work together to form a double reinforcement, realizing rapid cooling inside the display cabinet. When the beverage display case is operating at low load at night, with low heat load inside, the control system drives the cylinder 301 to retract, causing the fixing bar 302 and fixing rod 303 to move downwards. The second retracting mechanism 6 first releases the pressure on the elastic bladder 408, and the thermally conductive silicone oil automatically flows back from the thermally conductive cavity 406 into the elastic bladder 408, reducing unnecessary cold loss from the fins and avoiding cold waste. At the same time, it drives the retracting frame 501 to move downwards. The roller 511 moves relative to the roller while being pushed by the arc-shaped wall. The reinforcing rod 503 pulls the two double-ring rods 505 relative to each other, and the reinforcing rod 503 generates tension on both sides of the elastic diamond-shaped fins 401, causing them to change from a wide state to a narrow state. The small windward area of ​​the narrow state and the low thermal conductivity of the hollow cavity form a dual optimization. In addition, the sharp corners on both sides of the elastic diamond-shaped fins 401 are rounded, and the four external sides are all slightly arc-shaped. The mechanical width and narrow deformation, fluid heat conduction, and streamlined structure are deeply coupled to form a synergistic adaptive heat exchange system.
