Description

Technical Field

[0001] This invention relates to the field of evaporator technology, and more specifically to a high-efficiency dual-channel evaporator used in refrigeration systems. Background Technology

[0002] In a refrigeration system, the evaporator is the core component for generating cooling capacity. Its structural design directly determines the efficiency and stability of the system. Currently, most existing pipe evaporators adopt a single-pipe design with one inlet and one outlet. If a leak occurs at any point in the pipe, the entire refrigeration cycle will be interrupted, causing the entire unit to stop operating. Furthermore, the adaptability of a single-channel evaporator is also limited, meaning it can only serve one refrigeration system, which is quite restrictive.

[0003] Therefore, by installing two sets of pipes inside the evaporator to form a dual-channel evaporator, it can provide services to two refrigeration systems at the same time, which is more energy-efficient and effective. Furthermore, if one pipe leaks, the other channel can still operate normally, thus ensuring the continuity and stability of the equipment operation.

[0004] However, when installing pipes inside the evaporator, part of the pipes are usually "exposed" on the outside of the evaporator. If the equipment is running, the pipes are very likely to be damaged by physical impacts, and condensation and water leakage can easily cause problems such as pipe corrosion and seal failure, which will have an adverse effect on the overall reliability of the evaporator. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a high-efficiency dual-channel evaporator for use in a refrigeration system, which solves the technical problem in the related art that the external exposed pipes of the evaporator lack protective components and are easily damaged or corroded by bumps or condensation.

[0006] At least one embodiment of the present invention provides a high-efficiency dual-channel evaporator for use in a refrigeration system, including an evaporator body, a protective plate, a hinged plate, a fixing component, and a sealing component. Two protective plates are provided, and the two protective plates are respectively disposed on both sides of the evaporator body by mounting components. The protective plates have through grooves on their sides, and the hinged plate is hinged to the through grooves of the protective plates. The hinged plate can be opened for observation when the protective plates are installed on both sides of the evaporator body to observe the internal pipes.

[0007] Two fixing components are provided, and the two fixing components are respectively installed on the two protective plates to fix the opening and closing plate that blocks the through groove of the protective plate. Two gap filling components are provided, and the two gap filling components are both installed on the evaporator body to seal the gap between the protective plate and the evaporator body.

[0008] To protect the exposed pipes on both sides when using the evaporator body, the mounting assembly further includes slide rails, mounting blocks, clamping components, and limiting components. Two slide rails are provided, both fixedly mounted on the sides of the evaporator body. Four mounting blocks are provided, arranged in pairs, with two pairs of blocks fixedly mounted on the sides of the protective plate. The two pairs of blocks are slidably mounted on the sides of the two slide rails. The clamping components are located on the sides of the evaporator body, and the limiting components are located at the top of the evaporator body. The clamping components include clamping plates and clamping blocks. The clamping plates are fixedly mounted on the sides of the evaporator body, and two limiting components are fixedly mounted on the bottom of the protective plate. The clamping block has a top end with a groove that matches the bottom end of the clamping block. The limiting assembly includes a connecting frame, a connecting rod, a limiting rod, and a limiting block. Two connecting frames are fixedly installed between the top ends of the two protective plates, and two connecting rods are fixedly installed between the two connecting frames. The bottom end of each of the two connecting rods is fixedly installed with a limiting rod. Two limiting blocks are fixedly installed at the top end of the evaporator body. When the limiting rod is inserted into the limiting groove of the limiting block, the clamping block is precisely inserted into the groove of the clamping plate. The top end of the limiting block has a limiting groove that matches the bottom end of the limiting rod. The connecting frame allows the two protective plates to be installed on both sides of the evaporator body simultaneously.

[0009] To secure the opening and closing plate when sealing the through groove of the protective plate, the fixing assembly further includes a pull bracket, a fixing block, an abutment block, and a fixing frame. The pull bracket is fixedly installed on the side of the opening and closing plate, the fixing block is fixedly installed on the top of the pull bracket, the abutment block is fixedly installed on the side of the protective plate, one end of the fixing frame is slidably installed through the abutment block, the top of the fixing block has a slot, and the other end of the fixing frame is adapted to the slot.

[0010] Because a gap exists between the protective plate and the evaporator body when the protective plate is installed on the side of the evaporator body, the gap-sealing assembly further includes a plug, a bracket, a rod, and a gap-sealing frame to seal the gap. The plug is fixedly installed on both sides of the connecting frame, the bracket is installed on the plug, the rod is fixedly installed on the top of the bracket, and the gap-sealing frame is fixedly installed on the bottom of the rod. The top of the plug has a slot that matches the bottom of the bracket. When the bottom of the bracket is inserted into the slot of the plug, the bottom of the gap-sealing frame and the bottom of the protective plate are at the same horizontal level, and the height of the gap-sealing frame is the same as the height of the protective plate.

[0011] The present invention provides a high-efficiency dual-channel evaporator for use in a refrigeration system. Compared with the prior art, through the cooperation between the protective plate, the opening and closing plate, the fixing component and the sealing component, the protective plate can be installed on both sides of the exposed pipes of the evaporator body at the same time to protect them when the evaporator body is used. If it is necessary to observe the pipes on the side of the protective plate during protection, the pipes can be observed by opening the opening and closing plate and through the through groove of the protective plate. During protection, the opening and closing plate can be fixed by the fixing components, thereby blocking the through groove of the protective plate. In addition, the gap between the protective plate and the evaporator body can be sealed by the sealant assembly, thereby further protecting the pipes on both sides of the evaporator body and preventing condensate from dripping from the gaps into the pipes.

It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-9 As shown, this invention illustrates a high-efficiency dual-channel evaporator used in a refrigeration system, comprising an evaporator body 1, a protective plate 2, a hinged plate 3, a fixing component, and a gap-sealing component. Two fixing components are provided, each mounted on one of the two protective plates 2, for fixing the hinged plate 3 that seals the through groove of the protective plate 2. Two gap-sealing components are provided, each mounted on the evaporator body 1, for sealing the gap between the protective plate 2 and the evaporator body 1.

[0021] Two protective plates 2 are provided, each mounted on one side of the evaporator body 1 via an installation assembly. When using the evaporator body 1, the two protective plates 2 are installed on both sides of the evaporator body 1 via the installation assembly to protect the pipes. The installation assembly includes slide rails 4, mounting blocks 5, clamping components, and limiting components. Two slide rails 4 are provided, both fixedly mounted on the side of the evaporator body 1. Four mounting blocks 5 are provided, arranged in pairs, with two pairs of blocks fixedly mounted on the side of the protective plate 2. The two pairs of blocks 5 are slidably mounted on the side of the two slide rails 4. The clamping components are located on the side of the evaporator body 1, and the limiting components are located on the side of the evaporator body 1. At the top of the evaporator body 1, the clamping assembly includes a clamping plate 6 and a clamping block 7. The clamping plate 6 is fixedly installed on the side of the evaporator body 1. Two clamping blocks 7 are fixedly installed at the bottom of the protective plate 2. The top of the clamping plate 6 is provided with a groove that matches the bottom of the clamping block 7. The limiting assembly includes a connecting frame 8, a connecting rod 9, a limiting rod 10, and a limiting block 11. Two connecting frames 8 are fixedly installed between the tops of the two protective plates 2. Two connecting rods 9 are fixedly installed between the two connecting frames 8. The bottom of each connecting rod 9 is fixedly installed with a limiting rod 10. Two limiting blocks 11 are fixedly installed at the top of the evaporator body 1. The top of the limiting block 11 is provided with a limiting groove that matches the bottom of the limiting rod 10.

[0022] Specifically, during installation, the operator holds the connecting rod 9 and, with the connection of the connecting frame 8, moves the two protective plates 2 to both sides of the evaporator body 1. It should be noted that the sliding groove on the side of the slide rail 4 is open at both ends, meaning the mounting block 5 can slide into the groove of the slide rail 4 and can also be removed. During installation, the mounting block 5 slides into the groove of the slide rail 4, causing the protective plates 2 to slide vertically on both sides of the evaporator body 1. The sliding continues until the clamping block 7 at the bottom of the protective plate 2 inserts into the slot of the clamping plate 6. As it moves downwards, the connecting rod 9 and the limiting rod 10 move downwards simultaneously. When the limiting rod 10 inserts into the limiting groove of the limiting block 11, the clamping block 7 inserts precisely into the slot of the clamping plate 6. When the clamping block 7 is inserted into the slot of the clamping plate 6, the limiting rod 10 can insert into the limiting groove of the limiting block 11, thus limiting and fixing the protective plate 2 and protecting the pipes on both sides of the evaporator body 1.

[0023] When it is necessary to inspect the pipes during protection, the opening and closing plate 3 is hinged to the opening and closing plate 2 through the through groove on the side of the protective plate 2, so the pipes inside the protective plate 2 can be inspected through the through groove. When protection is needed, the opening and closing plate 3 can be closed to block the through groove, and then the opening and closing plate 3 can be fixed by the fixing components. The fixing components include a pull bracket 12, a fixing block 13, an abutment block 14, and a fixing frame 15. The pull bracket 12 is fixedly installed on the side of the opening and closing plate 3, the fixing block 13 is fixedly installed on the top of the pull bracket 12, the abutment block 14 is fixedly installed on the side of the protective plate 2, and one end of the fixing frame 15 is slidably installed in the abutment block 14.

[0024] Specifically, when the hinged plate 3 needs to be opened, the hinged plate 3 can be opened by using the pull bracket 12 as a relay point. During the opening, because the top of the fixing block 13 has a slot and the other end of the fixing frame 15 is adapted to the slot, the fixing frame 15 can be moved upward, so that one end of the fixing frame 15 passing through the fixing block 13 moves out of the fixing block 13. At this time, pulling the pull bracket 12 can open the hinged plate 3 and expose the through groove. When it is necessary to close, the hinged plate 3 can be used to block the through groove, and then the fixing frame 15 can be moved downward. At this time, the two sides of the fixing frame 15 are respectively inserted into the slot of the fixing block 13 and slide in the abutment block 14, thereby fixing the hinged plate 3. It should be added that a sealing strip is installed between the hinged plate 3 and the through groove.

[0025] Because a gap exists between the protective plate 2 and the evaporator body 1 when the protective plate 2 is slid into the groove of the slide rail 4 for installation, the gap can be sealed by a sealing assembly. The sealing assembly includes an insert block 16, an insert bracket 17, an insert rod 18, and a sealing frame 19. Insert blocks 16 are fixedly installed on both sides of the connecting frame 8, the insert bracket 17 is installed on the insert blocks 16, the insert rod 18 is fixedly installed on the top of the insert bracket 17, and the sealing frame 19 is fixedly installed on the bottom of the insert rod 18. Specifically, when sealing is required, the operator holds the insert bracket 17 and lowers it via the insert rod 18 and the sealing frame 19, thereby placing the sealing frame 19 between the protective plate 2 and the evaporator body 1. The top of the 16 has a slot that matches the bottom of the insert 17. When the bottom of the insert 17 is inserted into the slot of the insert 16, the bottom of the sealant frame 19 and the bottom of the protective plate 2 are at the same level. Then, the two ends of the insert 17 are inserted into the slots of the insert 16 to fix the sealant frame 19. At this time, the insert rod 18 passes through the connecting frame 8, which can further stabilize the sealant frame 19. The height of the sealant frame 19 is the same as the height of the protective plate 2. When the sealant frame 19 is placed in the gap, it can achieve a full-length seal of the vertical gap between the protective plate 2 and the evaporator body 1, preventing condensate and dust from entering from the gap and contacting the exposed pipes.

[0026] Working principle: When using the evaporator body 1, during installation, the operator holds the connecting rod 9 and, with the connection of the connecting frame 8, moves the two protective plates 2 to both sides of the evaporator body 1. At this time, the mounting block 5 slides into the groove of the slide rail 4, thereby causing the protective plates 2 to slide vertically on both sides of the evaporator body 1. When the protective plates 2 slide down, the clamping block 7 at the bottom of the protective plate 2 is inserted into the groove of the clamping plate 6. When moving down, the connecting rod 9 and the limiting rod 10 will move down synchronously. When the clamping block 7 is inserted into the groove of the clamping plate 6, the limiting rod 10 can be inserted into the limiting groove of the limiting block 11, thereby limiting and fixing the protective plates 2 and protecting the pipes on both sides of the evaporator body 1.

[0027] Then, the staff holds the insert bracket 17 and moves it down through the insert rod 18 and the sealant frame 19, thereby placing the sealant frame 19 between the protective plate 2 and the evaporator body 1. At this time, the two ends of the insert bracket 17 are respectively inserted into the slots of the insert block 16 to fix the sealant frame 19. At this time, the insert rod 18 passes through the connecting frame 8, which can further stabilize the sealant frame 19 and seal the gap between the protective plate 2 and the evaporator.

[0028] If it is necessary to inspect the pipeline during protection, the opening and closing plate 3 can be opened to inspect the pipeline inside the protective plate 2 through the through groove. When protection is needed, the opening and closing plate 3 can be closed to seal the through groove, and then the fixing bracket 15 can be lowered. At this time, the two sides of the fixing bracket 15 are respectively inserted into the slots of the fixing block 13 and slide in the abutment block 14, thereby fixing the opening and closing plate 3.

[0029] In use, the piping of the evaporator body 1 is divided into two equal parts, and the piping of the two parts is arranged symmetrically and at equal intervals. Using the same fins, the effect is consistent. The two parts of the piping can be connected to two refrigeration systems respectively. It is equivalent to one evaporator body 1 being used in two parts. The core advantage is that the "independent controllable flow channel" design is achieved through two independent refrigerant inlets and two independent outlets, realizing complete separation and precise control of the flow channel. It can specifically solve the performance bottleneck of single flow channel evaporators in multiple scenarios, and is suitable for scenarios with large fluctuations in refrigeration system load, uneven heat exchange demand, or high requirements for operational stability.

[0030] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
