Description

Technical Field

[0002] In response to the latest societal demands for food safety during processing, enhancing the sterilization and disinfection capabilities of food processing machinery has become essential. Low-tension spiral freezers, widely used in various food processing fields, offer a new option for the market when they incorporate pasteurization and high-temperature sterilization functions. These devices typically require operation at both -40°C and +80°C.

[0003] Current low-tension spiral devices mainly employ a motor built into the insulated storage chamber, using horizontal airflow to lower the internal temperature. Patent CN121297327B discloses a conventional heat dissipation layout where both the air source and heat exchanger are installed inside the insulated storage chamber. For food quick-freezing equipment supporting internal pasteurization, the motor must not only meet the freezing environment requirements of -40℃ but also the high-temperature sterilization requirements of +80℃. Under these conditions, conventional heat dissipation layouts have the following problems:

[0004] 1. The requirements for motor selection are more stringent, and conventional motors cannot be used in this working condition; 2. The motor generates heat during operation, affecting the internal low-temperature environment; 3. The motor occupies space in the warehouse, and maintenance personnel need to enter the warehouse at -40 degrees Celsius to disassemble and maintain it, resulting in a harsh working environment; or the motor can only be disassembled or maintained after the machine has been shut down.

[0005] Therefore, it is necessary to design a heat dissipation system that can move the motor from inside the storage chamber to outside the storage chamber and efficiently dissipate heat inside the low-tension spiral device. Summary of the Invention

Therefore, they should not be construed as limiting the scope of protection of this invention. The embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0029] It should be understood that the accompanying drawings are for illustrative purposes only.

[0030] A heat dissipation system with a suspended air intake structure, such as Figures 1-20 As shown, the device includes a storage body 1, an evaporator disposed within the storage body 1, a baffle shell connected to the evaporator, and an impeller communicating with the baffle shell. A connecting bracket 2 is disposed inside the storage body 1, and the baffle shell is connected to the connecting bracket. A motor bracket 3 is disposed outside the storage body 1, and a motor 31 is disposed on the motor bracket 3. The impeller 211 is disposed in the connecting bracket 2, and the rotating shaft 32 of the motor 31 passes through the storage body 1 and is connected to the impeller 211. A support frame 64 is disposed below the connecting bracket 2, and the support frame 64 is connected to both the connecting bracket 2 and the evaporator 61. A sealing connection structure 4 is disposed on the storage body 1, and the two ends of the sealing connection structure 4 are respectively connected to the connecting bracket 2 and the motor bracket 3, sealing the connecting bracket 2 and the motor bracket 3 to the storage body 1.

[0031] like Figures 2-3 , Figure 10 As shown, the storage body 1 is constructed from several storage body panels 12, and the interior formed by the enclosed space of the several storage body panels 12 is the operating space. A storage body bottom plate 11 is provided on the bottom surface of the storage body 1 to prevent damage to the ground area below the storage body 1 when the interior is too cold.

[0032] The evaporator 61 is located inside the storage chamber 1 and is not in contact with the storage chamber plate 12. An evaporator support 62 is provided on the bottom plate 11 of the storage chamber. The evaporator 61 is mounted on the evaporator support 62 to facilitate ventilation. The air inside the operating space can flow directly to the evaporator 61 or flow to the evaporator 61 through the evaporator support 62. The wind baffle shell 63 is located above the evaporator 61 and covers the evaporator 61. The wind baffle shell 63 and the evaporator 61 are stacked vertically and are connected to the evaporator 61. The air flowing out of the evaporator 61 enters the wind baffle shell 63 and is then guided from the wind baffle shell 63 to the impeller 211.

[0033] like Figure 17-19 As shown, a fixing plate 631 is provided on the side of the windshield housing 63 near the impeller 211. The fixing plate 631 can move freely, facilitating installation and adjustment when connected to the impeller 211. After installation and adjustment, the fixing plate 631 and the windshield housing 63 are detachably connected. In this design, a bolt connection is used. An air guide port is provided on the fixing plate 631. The impeller 211 communicates with the interior of the windshield housing 63 through the air guide port, drawing cold air from the evaporator 61 into the windshield housing 63 and blowing it out of the windshield housing 63 through the impeller 211. The impeller 211 directs the air towards the top of the storage unit 1.

[0034] The windshield housing 63 has a maintenance ramp on the side away from the impeller 211. Specifically, one side of the windshield housing 63 is set as a ramp, preferably on the side away from the impeller 211, to facilitate maintenance. A maintenance door 632 is provided on the maintenance ramp. Opening the maintenance door 632 allows operators to enter the windshield housing 63 to maintain the impeller 211. To facilitate operator access, a maintenance ladder 633 is provided at the maintenance door 632, allowing operators to enter the windshield housing 63 or climb to its top using the maintenance ladder 633.

[0035] like Figure 20As shown, a fan guide ring 212 is provided on the impeller 211. The fan guide ring 212 is connected to the windproof housing 63. Specifically, the rotating shaft 32 of the motor 31 drives the impeller 211 to rotate. The fan guide ring 212 is located on the side away from the rotating shaft 32 and is connected to the fixing plate 631. Furthermore, both the fan guide ring 212 and the fixing plate 631 are provided with connecting holes. Connecting parts are provided through the fan guide ring 212 and the fixing plate 631 to connect the fan guide ring 212 and the fixing plate 631 together. As the impeller 211 rotates, the air on the evaporator 61 flows towards the baffle shell 63, and is conveyed and guided by the fan guide ring 212, blowing towards the top of the storage unit 1; or, as the impeller 211 rotates, the air on the evaporator support flows towards the evaporator 61, enters the baffle shell 63 after passing through the evaporator 61, and is conveyed and guided by the fan guide ring 212, finally being thrown by the impeller 211 into the space above the storage unit 1, forming a high-pressure zone in the space above, thereby delivering cold air to the frozen product area. The impeller 211 can be any model; in this design, the impeller 211 is a centrifugal fan.

[0036] The connecting bracket 2 is disposed between the windproof housing 63 and the storage plate 12, inside the storage body 1. The connecting bracket 2 is connected to the windproof housing 63 and the support frame 64 respectively. The support frame 64 is connected to the evaporator 61 and the bottom plate 11 of the storage body respectively. The windproof housing 63 is connected to the evaporator 61. All structures are connected as a whole, which better suppresses the vibration of the motor 31 and the impeller 211. Furthermore, one side of the connecting bracket 2 is connected to the fixing plate 631, and the other side is connected to the motor bracket 3 through the sealing connection structure 4. The connecting bracket 2 has a frame structure. The impeller is placed inside the connecting bracket 2 but does not contact the connecting bracket 2, so that air can be blown out from the top of the connecting bracket 2 when the impeller 211 is running.

[0037] The support frame 64 is located at the bottom of the connecting bracket 2 and extends toward the bottom plate 11 of the storage body, connecting with the bottom plate 11 of the storage body, and is used to support the connecting bracket 2 and suppress the vibration of the motor 31. A first baffle plate 641 is provided between the connecting bracket 2 and the support frame 64, and a second baffle plate 642 is provided between the support frame 64 and the evaporator 61. The first baffle plate 641 prevents the air coming from the evaporator bracket 62 from not flowing through the evaporator 61, but directly flowing through the support frame 64 to the impeller 211. The second baffle plate 642 prevents the air coming from the evaporator 61 from not flowing through the baffle shell 63, but directly flowing through the support frame 64 to the impeller 211. As a result, a complete and orderly heat dissipation air path cannot be formed, resulting in poor heat dissipation effect on the evaporator 61. This causes the air from inside the condenser 1 to flow sequentially through the evaporator 61, the baffle shell 63 and the impeller 211 to form a heat dissipation air path, or to flow sequentially through the evaporator bracket 62, the evaporator 61, the baffle shell 63 and the impeller 211 to form a heat dissipation air path. Furthermore, the support frame 64 also serves as scaffolding. In this case, the first wind deflector 641 or the support frame 64 provides a working surface, which facilitates the inspection and installation of the impeller 211 and / or the sealing connection structure 4.

[0038] The motor bracket 3 supports the motor 31. A motor mounting plate is provided on the motor bracket 3, and the motor 31 is mounted on the motor mounting plate. The motor mounting plate and the motor bracket 3 can be bolted or welded together. In this design, the motor mounting plate is welded to the motor bracket 3 to prevent the motor mounting plate from falling off the motor bracket 3 when the motor 31 vibrates during operation. To ensure reliable fixation of the motor 31 to the motor mounting plate, a connector is provided on the motor 31 to fix the motor 31 to the motor mounting plate. The connector can be any structure that can stably connect the motor to the motor mounting plate; in this design, the connector is a bolt.

[0039] Connecting rods extend from both the motor bracket 3 and the connecting bracket 2 toward the storage body plate 12, connecting the motor bracket 3, the connecting bracket 2, and the storage body plate 12. The two ends of the sealing connection structure 4 are connected to the motor bracket 3 and the connecting bracket 2 respectively, preventing cold air from escaping from the interior of the storage body 1 to the exterior. Specifically, a storage body connecting plate is provided at the end of the connecting rod near the storage body plate 12, and the storage body connecting plate is connected to the sealing connection structure 4. The sealing connection structure 4 is configured one-to-one with the connecting rods extending from the motor bracket 3 or the connecting bracket 2, ensuring a sealed connection between the bracket and the storage body 1.

[0040] The sealing connection structure 4 has two embodiments: Example 1 like Figure 3-7As shown, the sealing connection structure 4 includes a connector and a seal. The connector includes a plurality of through connectors 42. The seal is a sealing block 43. The sealing block 43 is inserted into the housing plate 12. The plurality of through connectors 42 pass through the housing connecting plate of the motor bracket 3, the sealing block 43 and the housing connecting plate of the connecting bracket 2 from the outside to the inside. Of course, they can also be connected from the inside to the outside to achieve a sealed connection between the motor bracket 3, the sealing connection structure 4 and the connecting bracket 2.

[0041] The sealing block 43 is made of an elastic material, which is not strong enough. Therefore, a reinforcing member 41 is provided on the sealing block 43. The reinforcing member 41 is sleeved on the sealing block 43 to increase the strength of the sealing block 43. Specifically, the reinforcing member 41 includes a first reinforcing ring 411 and a second reinforcing ring 412 connected together. When the reinforcing member 41 is sleeved on the sealing block 43, the first reinforcing ring 411 is located at the end of the sealing block 43, and the second reinforcing ring 412 is sleeved on the sealing block 43, which enhances the strength of the sealing connection structure 4 and makes the connection reliable. Furthermore, the first reinforcing ring 411 extends radially along the sealing block 43, and the second reinforcing ring 412 extends axially along the sealing block 43. The first reinforcing ring 411 protrudes from the second reinforcing ring 412. When the sealing connection structure 4 is provided on the tank plate 12, the second reinforcing ring 412 is accommodated within the tank plate 12, and the first reinforcing ring 411 is located outside the tank plate 12. The first reinforcing ring 411 protruding from the second reinforcing ring 412 can not only form a limit but also increase the strength.

[0042] Of course, one or two reinforcing members 41 can be provided. When one reinforcing member 41 is provided, the first reinforcing ring 411 is located at both ends of the second reinforcing ring 412. When two reinforcing members 41 are provided, only one first reinforcing ring 411 is provided on each reinforcing member 41, and the two reinforcing members 41 are respectively sleeved on both ends of the sealing block 43.

[0043] The reinforcing member 41 is tightly connected to the sealing block 43.

[0044] When the sealing block 43 is inserted into the storage plate 12, the cold air inside the storage 1 flows out through the gap between the sealing block 43 and the storage plate 12. A sealing protrusion 44 is provided at the end of the sealing block 43, protruding from the sealing block 43 to seal the gap between the sealing block 43 and the storage plate 12, preventing cold air from escaping. When the reinforcing member 41 is fitted with the sealing block 43, the first reinforcing ring 411 abuts against the sealing protrusion 44. When the several through-connectors 42 connect the sealing connection structure 4 to the storage plate 12, the first reinforcing ring 411 abuts against the storage plate 12. Through the fastening of the several through-connectors 42, the sealing protrusion 44 and the first reinforcing ring 411 are pressed towards the storage plate 12 to seal the gap between the sealing block 43 and the storage plate 12, ensuring a better sealing effect.

[0045] The sealing protrusion 44 is reliably connected to the sealing block 43. In this solution, the sealing protrusion 44 and the sealing block 43 are integrally formed.

[0046] Furthermore, the sealing block 43 can be provided as one, two, or other types. When multiple sealing blocks 43 are provided, they are connected sequentially along their axial direction. In this embodiment, two sealing blocks 43 are provided, with the sides of the two sealing blocks 43 close to each other tightly connected, and sealing protrusions 44 provided on the sides of the two sealing blocks 43 far from each other.

[0047] The sealing block 43 is made of an elastic heat insulation material, preferably rubber.

[0048] Example 2 like Figure 10-16 As shown, the sealing connection structure 4 includes a connector and a seal. The connector passes through the seal, and the seal is inserted into the tank plate 12. The connector includes a motor connector 47 and a fan connector 48. At least one of each is provided. The motor connector 47 connects the motor bracket 3 and the seal, and the fan connector 48 connects the connecting bracket 2 and the seal. The fan connector 48 and the motor connector 47 are staggered.

[0049] Furthermore, the sealing element includes a first fixing member 45 and a second fixing member 46. The first fixing member 45 includes a first connecting plate 451, a second connecting plate 452 and a first connecting rod 453. One end of the first connecting rod 453 is connected to the first connecting plate 451 and the other end is connected to the second connecting plate 452. There is a space between the first connecting plate 451 and the second connecting plate 452. Specifically, when the first fixing member 45 is inserted into the storage body 1, the first connecting plate 451 is located outside the storage body plate 12, and the second connecting plate 452 is accommodated inside the storage body plate 12.

[0050] The second fixing member 46 includes a third connecting plate 461, a fourth connecting plate 462, and a second connecting rod 463. One end of the second connecting rod 463 is connected to the third connecting plate 461, and the other end is connected to the fourth connecting plate 462. There is a space between the third connecting plate 461 and the fourth connecting plate 462. Specifically, when the second fixing member 46 is inserted into the storage plate 12, the third connecting plate 461 is located outside the storage plate 12, and the fourth connecting plate 462 is accommodated inside the storage plate 12.

[0051] When the first fixing member 45 and the second fixing member 46 are connected, the first connecting plate 451 and the third connecting plate 461 are far apart from each other, and the second connecting plate 452 and the fourth connecting plate 462 abut against each other.

[0052] In this solution, the first fastener 45 and the second fastener 46 have the same structure.

[0053] The motor connector 47 passes through the first connecting plate 451 and the second connecting plate 452, and then through the fourth connecting plate 462 to connect the motor bracket 3 and the sealing connection structure 4. The fan connector 48 passes through the third connecting plate 461 and the fourth connecting plate 462, and then through the second connecting plate 452 to connect the connecting bracket 2 and the sealing connection structure 4. The motor connector 47 and the fan connector 48 are staggered and do not contact each other, so there is no heat exchange between the connectors.

[0054] A plurality of first external connection holes 454 are provided on the first connecting plate 451, and the plurality of first external connection holes 454 are evenly arranged along the circumference of the first connecting plate 451. A plurality of first internal connection holes 455 are provided on the second connecting plate 452, and the plurality of first internal connection holes 455 are evenly arranged along the circumference of the second connecting plate 452. A plurality of second external connection holes 464 are provided on the third connecting plate 461, and the plurality of second external connection holes 464 are evenly arranged along the circumference of the third connecting plate 461. A plurality of second internal connection holes 465 are provided on the fourth connecting plate 462, and the plurality of second internal connection holes 465 are evenly arranged along the circumference of the fourth connecting plate 462. After the motor connector 47 passes through the first external connection hole 454, the first internal connection hole 455 and the second internal connection hole 465, the fan connector 48 passes through the second external connection hole 464, the other second internal connection holes 465 and the other first internal connection holes 455. Since the two different connectors cannot be inserted into the same hole at the same time, no heat exchange is formed between the connectors, thus preventing the cold energy inside the storage body 1 from dissipating through the connectors.

[0055] In this solution, to achieve the staggered connection between the motor connector 47 and the fan connector 48, the number of the first internal connecting hole 455 or the second internal connecting hole 465 is greater than or equal to twice the number of connectors to ensure reliable connection, and the number of the first external connecting hole 454 or the second external connecting hole 464 is equal to or greater than the number of connectors.

[0056] Because the first internal connecting hole 455 and the second internal connecting hole 465 are located inside the entire structure, to facilitate the installation of the motor connector 47 and the fan connector 48, fixed support plates 49 are provided on the side of the second connecting plate 452 near the first connecting plate 451 and on the side of the fourth connecting plate 462 near the third connecting plate 461. Specifically, the first fixed support plate is provided on the second connecting plate 452, and the second fixed support plate is provided on the fourth connecting plate 462. Mounting holes 492 are provided on both the first and second fixed support plates. The mounting holes 492 of the support plate are each corresponding to the first internal connecting holes 455. The mounting holes 492 of the second fixed support plate are each corresponding to the second internal connecting holes 465. A rivet nut 491 is provided in the mounting holes 492 at intervals. The rivet nut 491 is oriented towards the internal connecting holes. When the first fixed support plate is connected to the second connecting plate 452, the rivet nut 491 is inserted into the first internal connecting hole 455 at intervals. When the second fixed support plate is connected to the fourth connecting plate 462, the rivet nut 491 is inserted into the second internal connecting hole 465 at intervals.

[0057] A reinforcing support plate 40 is provided on the side of the first connecting plate 451 near the second connecting plate 452 and on the side of the third connecting plate 461 near the fourth connecting plate 462. Specifically, the first reinforcing support plate is provided on the first connecting plate 451, and the second reinforcing support plate is provided on the third connecting plate 461. Reinforcing connection holes 401 are provided on the reinforcing support plates 40. The reinforcing connection holes 401 on the first reinforcing support plate correspond one-to-one with the first external connection holes 454, and the reinforcing connection holes 401 on the second reinforcing support plate correspond one-to-one with the second external connection holes 464, which are used to enhance the overall strength of the sealing component.

[0058] For ease of connection, both the fixed support plate 49 and the reinforcing support plate 40 are designed as semicircles, and the two semicircles are snapped together.

[0059] To achieve quick alignment between the first fixing member 45 and the second fixing member 46, a limiting protrusion 456 is provided on the first fixing member 45, and a limiting groove 457 is provided on the second fixing member 46. When the first fixing member 45 and the second fixing member 46 are connected, the limiting protrusion 456 is inserted into the limiting groove 457.

[0060] After the sealing connection structure 4 is connected, foam adhesive is placed between the sealing connection structure 4 and the tank plate 12 to fill the gap between them and prevent cold from escaping.

[0061] like Figure 8 , Figure 9 As shown, the rotating shaft 32 of the motor 31 is directly connected to the impeller 211 through the housing plate 12. The housing plate 12 has a certain thickness, and the shaft length required for the rotating shaft 32 to pass through the housing plate 12 is very long. The longer the shaft length, the easier it is to amplify the vibration and other problems that occur when the impeller 211 is running. Therefore, a plate 5 is provided on the housing plate 12. A placement groove 51 is provided on the side of the plate 5 near the motor 31. The end of the rotating shaft 32 of the motor 31 is located in the placement groove 51, so that the distance between the motor 31 and the impeller 211 is shortened. A connecting hole 52 is provided on the placement groove 51, and the rotating shaft 32 of the motor 31 passes through the connecting hole 52 to connect to the impeller 211.

[0062] Furthermore, a snap-fit ​​groove 53 is provided on the outer periphery of the panel 5, which is connected to the body plate 12 and is used to limit the position of the panel 5.

[0063] The material filled in the panel 5 is the same as that of the cabinet panel 12, which helps to shorten the length of the motor shaft without completely sacrificing the heat preservation effect of the corresponding position of the motor.

[0064] After the shaft 32 of the motor 31 passes through the connecting hole 52 and connects to the impeller 211, foam adhesive is placed between the insert 5 and the tank plate 12 according to the position of the insert 5 to seal the insert 5 and the tank plate 12.

[0065] In this design, all connectors 42 are bolts.

[0066] This invention primarily designs a heat dissipation system with a suspended suction structure. By installing a motor bracket 3 on the outside of the storage unit 1, the motor 31 is suspended externally, freeing up usable space inside the storage unit 1. This makes the overall structure of the equipment more compact, reducing costs. Simultaneously, the heat generated by the motor 31 does not affect the internal low-temperature environment, effectively improving the internal hygiene quality of the equipment. Furthermore, the motor 31 does not need to operate in conditions ranging from -40℃ to +80℃, reducing the operating cost of the motor 31. This effectively avoids the impact on the motor 31 and related accessories during normal spiral freezing at -40℃ and high-temperature sterilization at +80℃, extending the overall service life of the motor 31 and facilitating motor disassembly. A sealed connection structure 4 is also provided to tightly connect the motor bracket 3, connecting bracket 2, and storage unit plate 12, preventing the leakage of internal cold or hot air and affecting the internal temperature of the storage unit 1. The insert plate 5 shortens the length of the motor 31's shaft 32, preventing excessive radial vibration during operation, and also facilitates connection to the motor 31 without requiring precise control of the position of the connection hole 52. The motor connector 47 and fan connector 48 on the sealed connection structure 4 are staggered to prevent cold air leakage. The motor bracket 3, connecting bracket 2, support frame 64 and evaporator bracket 62 are connected in sequence, so that the bracket structure in this solution is connected as a whole. At the same time, the support frame 64 is grounded to suppress the vibration of the motor 31.
