Description

Technical Field

[0001] This utility model is an evaporator baffle, belonging to the field of evaporator technology. Background Technology

[0002] In the manufacturing process of plate evaporators, two thin plates need to be welded together. During processing, the opposing surfaces of these two plates undergo a special treatment, concave inwards, ultimately forming a unique S-shaped medium channel. After the concave shape is formed, the two plates are tightly connected along their edges using a precise welding process, thus creating the plate evaporator. In the design and manufacturing of plate evaporators, thinner plates are typically selected to achieve better heat exchange performance. This is because thinner plates can effectively shorten the heat transfer path, reduce thermal resistance, thereby accelerating the heat exchange rate and improving the heat exchange efficiency of the evaporator.

[0003] However, this design also presents some problems. When welding the edges of the two thin plates, the actual welded joint area is relatively small due to the thinness of the plates themselves. This is to avoid defects such as burn-through and deformation during welding and to ensure weld quality. Furthermore, to avoid affecting the flow of the medium between the plates and the heat exchange process, the middle section of the two plates cannot be welded. These structural characteristics result in insufficient pressure resistance in plate-type evaporators. In actual use, the medium inside the evaporator will generate a certain pressure, and various stresses may also occur in the external environment. The small welded joint area and the unwelded middle region affect the integrity and strength of the overall evaporator structure, making it difficult to withstand greater pressure and prone to deformation or even cracking, thus affecting the normal operation and service life of the evaporator. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an evaporator baffle to solve the problems mentioned in the background art. This utility model increases the welding connection range between two thin plates and improves the compressive strength.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an evaporator baffle, comprising two thin plates, the two thin plates being fitted together, and the opposing surfaces of the two thin plates being recessed to form medium channels. A first pipe joint and a second pipe joint are respectively installed at both ends of the space formed by the two medium channels. A frame is installed on the opposing sides of the two thin plates, and the two frame joints are welded together. Multiple horizontal plates are evenly installed on the side of the frame away from the thin plates. An elongated oval opening is opened on the side of the horizontal plate facing the thin plates, and a screw is inserted into the elongated oval opening. One end of the screw contacts the thin plate, and two nuts are threaded onto the screw. The two nuts on one screw are respectively located on both sides of the elongated oval opening.

[0006] Furthermore, a first conical sleeve is fitted onto one end of the first pipe connector near the thin plate, and the larger end of the first conical sleeve is connected and fixed to both side frames.

[0007] Furthermore, a reinforcing plate is fixedly connected to the outer surface of the first conical sleeve, and the reinforcing plate is fixedly connected to the thin plate.

[0008] Furthermore, a second conical sleeve is fitted onto one end of the second pipe joint near the thin plate, and the larger end of the second conical sleeve is connected and fixed to both side frames.

[0009] Furthermore, a reinforcing plate is fixedly connected to the outer surface of the second conical sleeve, and the reinforcing plate is fixedly connected to the thin plate.

[0010] Furthermore, the thin plate has a rectangular structure, and the frame has a rectangular structure.

[0011] Furthermore, the medium channel has an "S" shaped structure, and both open ends of the medium channel extend to one edge of the thin plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Install welded frames on the back of two thin plates, with horizontal plates featuring elongated openings on the frames, allowing the two plates to be connected and supported at more points. Welding the two frames together increases the connection range between the two thin plates.

[0014] 2. Multiple screws are inserted into the elongated openings of several horizontal plates, with one end of each screw contacting the thin plate. Two nuts are then used to restrict the relative position of the screws and the horizontal plates. The structure formed by the screws, nuts, horizontal plates, and frame effectively holds the thin plate, dispersing pressure, improving overall compressive strength, and reducing the risk of deformation and cracking under medium pressure and external stress, thus ensuring stable operation of the evaporator. Strengthening the connection between the thin plates from multiple points and surfaces avoids weak connections caused by small welding areas. This better maintains structural integrity during long-term use, extending the evaporator's service life. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: an evaporator baffle, comprising two thin plates 1, which are fitted together. The thin plates 1 are rectangular in structure, and the opposite surfaces of the two thin plates 1 are recessed to form a medium channel 4. The medium channel 4 is an "S"-shaped structure, and the two open ends of the medium channel 4 extend to one edge of the thin plate 1. A first pipe connector 6 and a second pipe connector 7 are respectively installed at both ends of the space formed by the two medium channels 4. A first conical sleeve 5 is fitted on the end of the first pipe connector 6 near the thin plate 1 and is fixed to the first pipe connector 6. The large end of the first conical sleeve 5 is fixed to both frame 2. The design of the first conical sleeve 5 facilitates the connection between the first pipe connector 6 and the frame 2. A second conical sleeve 8 is fitted on the end of the second pipe connector 7 near the thin plate 1 and is fixed to the second pipe connector 7. The large end of the second conical sleeve 8 is fixed to both frame 2. The design of the second conical sleeve 8 facilitates the connection between the second pipe connector 7 and the frame 2. A reinforcing plate 9 is fixed to the outer surface of the first conical sleeve 5 and the outer surface of the second conical sleeve 8. The reinforcing plate 9 is fixed to the thin plate 1. In the design of this evaporator baffle, a first conical sleeve 5 and a second conical sleeve 8 are respectively fitted tightly to the first pipe joint 6 and the second pipe joint 7. The first conical sleeve 5 and the second conical sleeve 8 not only achieve a stable connection with the corresponding first pipe joint 6 and second pipe joint 7 in terms of installation, but also have a reinforcing plate 9 connected to their outer surface. The other end of the reinforcing plate 9 is fixed to the thin plate 1, forming a stable connection structure. This carefully designed structure greatly enhances the connection strength between the first pipe joint 6, the second pipe joint 7 and the thin plate 1 and the frame 2. When the evaporator is in operation and the medium is continuously entering and exiting, the first pipe joint 6 and the second pipe joint 7 will be subjected to considerable pressure. Thanks to the synergistic effect of the first conical sleeve 5, the second conical sleeve 8 and the reinforcing plate 9, the first pipe joint 6 and the second pipe joint 7 can better cope with this pressure, effectively avoiding common problems such as loosening and leakage. This structural optimization significantly improves the overall structural strength and reliability of the evaporator, ensuring the evaporator remains stable during long-term operation, reducing the probability of failure, extending the service life of the equipment, and providing more reliable protection for related industrial production processes.

[0023] See Figure 1 and Figure 2Each of the two thin plates 1 has a frame 2 mounted on its back side. The frame 2 is a rectangular structure, and the two frames 2 are welded together. By welding the two frames 2 together, this method breaks through the limitations of traditional connection range and greatly expands the connection area between the two thin plates 1. Compared with traditional connection methods, it not only increases the number of connection points but also expands the connection area, resulting in a qualitative improvement in the stability and robustness of the entire structure. This multi-position connection and support structure design can effectively disperse pressure and reduce stress concentration, enabling the evaporator to maintain good performance and structural integrity when facing internal medium pressure and external complex environmental stress, greatly improving the evaporator's pressure resistance and reliability.

[0024] See Figures 1-4 Multiple horizontal plates 3 are evenly installed on the side of the frame 2 away from the thin plate 1. Each horizontal plate 3 has an elongated oval opening 12 along its length on the side facing the thin plate 1. A screw 10 is inserted into each oval opening 12, with one end of the screw 10 in contact with the thin plate 1. Two nuts 11 are threaded onto each screw 10, with the two nuts 11 positioned on either side of the oval opening 12. Multiple horizontal plates 3 each have an elongated oval opening 12, and multiple screws 10 are inserted into these openings. The screw 10 is in close contact with the thin plate 1, and the relative position between the screw 10 and the horizontal plate 3 is limited by the two nuts 11 positioned on either side of the oval opening 12. In this way, the screws 10, nuts 11, horizontal plates 3, and frame 2 together form a stable structural system, effectively pressing down on the thin plate 1. This design possesses excellent mechanical properties and can cleverly distribute pressure. When the medium inside the evaporator generates pressure, this structure can evenly distribute this pressure to each connection point and surface, greatly improving the overall pressure resistance and significantly reducing the risk of deformation and cracking of the thin plate 1 under pressure, thus providing a solid guarantee for the stable operation of the evaporator.

[0025] Meanwhile, this structural design strengthens the connection between the thin plates 1 at multiple points and surfaces. Unlike traditional methods that rely solely on edge welding and have a limited connection range, it effectively compensates for the weak connection caused by a small welding area. During the long-term use of the evaporator, even under frequent pressure changes and the influence of the external environment, this structure can still maintain good stability and better preserve the integrity of the overall structure, thereby extending the service life of the evaporator, reducing equipment maintenance costs and replacement frequency, and bringing higher economic benefits and operational reliability to related production activities.
