Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a plate-type indirect evaporative cooling heat exchanger. Background Technology

[0002] Plate indirect evaporative cooling heat exchangers are a type of high-efficiency heat exchange equipment commonly used in modern air conditioning and industrial cooling systems. They achieve heat transfer through fluid flow and evaporation between plates, and have advantages such as compact structure, high heat transfer efficiency, energy saving and environmental protection. In existing plate indirect evaporative cooling heat exchangers, a fixed number of plates are usually used to meet specific heat exchange requirements.

[0003] However, adding or removing plates in traditional heat exchangers often requires a complex process, which may involve bending the plates to move them between the upper and lower guide rods. This can easily damage the plates, affecting the overall performance and lifespan of the heat exchanger. Furthermore, the plates are usually fixed by screws on the sides, which is a relatively fixed method that requires the use of bolts and screws for fixation. This makes it inconvenient to add plates, as it can only maintain a fixed length and cannot be adjusted according to the number of plates. Therefore, a plate-type indirect evaporative cooling heat exchanger is needed to solve the shortcomings of the existing system. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a plate-type indirect evaporative cooling heat exchanger, including a fixed frame 1, end plate one 2, end plate two 3, upper guide rod 4, lower guide rod 5, and limiting plate 6. End plate one 2 is fixedly connected to the front end of the fixed frame 1. The upper guide rod 4 and lower guide rod 5 are both fixedly connected to the opposite sides of end plate one 2 and end plate two 3. The limiting plate 6 is located on the opposite sides of end plate one 2 and end plate two 3, and the upper guide rod 4 and lower guide rod 5 both movably pass through the limiting plate 6. Several plates 7 are provided on the opposite sides of the limiting plate 6 and end plate one 2, and the top and bottom of the plates 7 are... The upper guide rod 4 and the lower guide rod 5 are movably connected to each other. The end plate 2 3 is threaded with a limit rod. The front end of the limit rod abuts against the surface of the limit plate 6, so that the clamp between the limit plate 6 and the end plate 2 can be tightly connected. A set of symmetrical limit components 8 is provided on the front side of the fixing frame 1, and the limit components 8 are in contact with the side of the plate 7. The lower guide rod 5 has a notch 9, and the inner side of the notch 9 is movably connected to the moving frame 10. The lower guide rod 5 is provided with a drive component 11, and the drive component 11 is fixedly connected to the inner side of the moving frame 10.

[0022] like Figure 1 and Figure 3 As shown, the limiting assembly 8 includes a rotating rod 801, a moving rod 802, an auxiliary wheel 803, a control rod 804, a limiting band 805, and a support rod 806. The top and bottom ends of the rotating rod 801 are fixedly connected to the auxiliary wheel 803. The support rod 806 is movably connected to the inner side of the fixed frame 1 via bearings, and a set of symmetrical limiting bands 805 are wound around the outer side of the support rod 806. The limiting bands 805 are respectively attached to the outer side of the auxiliary wheel 803, and the end of the limiting band 805 away from the support rod 806 is fixedly connected to the inner side of the fixed frame 1. The rotating rod 801 passes through the front end of the moving rod 802, and the rotating rod 801 is movably connected to the moving rod 802. The outer side of the control rod 804 is threaded, and the control rod 804 is movably connected to the auxiliary wheel 803 via the thread. Inside the moving rod 802, one side of the limiting band 805 is attached to the side of the plate 7, and both the limiting plate 6 and the moving rod 802 movably pass through the end plate 2. A set of symmetrical servo motors 12 are fixedly connected to the back side of the fixed frame 1, and the output end of the servo motor 12 is fixedly connected to one end of the control rod 804. Two sets of symmetrical guide rods 13 are provided inside the fixed frame 1. The guide rods 13 movably pass through the end plate 2, and the rotating rod 801 passes through the front end of the guide rod 13. The rotating rod 801 is movably connected to the guide rod 13. The moving rod 802 is located on the opposite side of the guide rod 13. A set of symmetrical servo motors 14 are fixedly connected to the top of the fixed frame 1, and the output end of the servo motors 14 is fixedly connected to the top of the support rod 806.

[0023] If the number of plates 7 increases, servo motor 12 and servo motor 14 are started simultaneously, driving the control rod 804 to rotate. Since the control rod 804 is threadedly connected to the moving rod 802, and the end plate 2 restricts the direction of movement of the moving rod 802, the moving rod 802 is driven to move horizontally forward, pushing the rotating rod 801 forward. The guide rod 13 moves synchronously. Since one end of the limiting band 805 is fixedly connected to the inner side of the fixed frame 1, when the auxiliary wheel 803 moves with the rotating rod 801 and the rotating rod rotates, the support rod 806 rotates, and the limiting band 805 gradually loosens. Thus, the extended part of the limiting band 805 fits along the side of the increased clamping piece, and the limiting band 805 remains taut. Therefore, the length of the limiting band 805 can be freely adjusted according to the number of plates 7, so as to fully limit and protect the side of the plates 7. The operation is simple and adaptable to limiting different numbers of plates 7.

[0024] like Figure 1 and Figure 4 As shown, the drive assembly 11 includes a drive rod 1101, a connecting rod 1102, and a slider 1103. The slider 1103 and the connecting rod 1102 are symmetrically arranged. The top end of the connecting rod 1102 is movably connected to the inner side of the moving frame 10 through a rotating shaft, and the bottom end of the connecting rod 1102 is movably connected to the top end of the slider 1103 through a rotating shaft. A set of symmetrical threads is provided on the outer side of the drive rod 1101. The drive rod 1101 passes through the slider 1103, and the drive rod 1101 and the slider 1103 are threadedly connected. The drive rod 1101 is movably connected to the inside of the lower guide rod 5 through a bearing, and the slider 1103 is slidably connected to the inside of the lower guide rod 5. A servo motor 15 is fixedly connected to the outer side of the end plate 2 3. The output end of the servo motor 3 15 is fixedly connected to one end of the drive rod 1101.

[0025] Start the servo motor 15 to drive the drive rod 1101 to rotate. Since the drive rod 1101 is threadedly connected to the slider 1103 and the slider 1103 is slidably connected inside the lower guide rod 5, the sliders 1103 move away from each other, causing the two connecting rods 1102 to rotate, thereby pulling the moving frame 10 to move downward along the notch 9, removing the obstruction of the notch 9, and thus moving the plate 7 to the notch 9 along the upper guide rod 4 and the lower guide rod 5. The notch 9 increases the longitudinal space between the upper guide rod 4 and the lower guide rod 5, providing movable space for the installation of the plate 7, avoiding assembly by bending the plate 7, reducing the damage caused by bending the plate 7, and thus making it convenient to increase or decrease the number of plates 7.

[0026] Working principle: In use, firstly, a limit rod is threaded onto end plate 2 3. The front end of the limit rod abuts against the surface of limit plate 6, thereby ensuring a tight connection between the clamping piece between limit plate 6 and end plate 2. If it is necessary to add or remove plates 7, the limit rod is rotated outward to release the restriction on limit plate 6, allowing it to move to the other end of notch 9. Then, servo motor 3 15 is started, driving drive rod 1101 to rotate. Since drive rod 1101 is threadedly connected to slider 1103, and slider 1103 is slidably connected inside lower guide rod 5, sliders 1103 move away from each other, driving two connecting rods 1102 to rotate, thereby pulling moving frame 10 downward along notch 9, releasing the obstruction of notch 9, and thus moving plate 7 to the notch along upper guide rod 4 and lower guide rod 5. The number of plates 7 can be easily increased or decreased at 9 locations. If the number of plates 7 is increased, servo motor 12 and servo motor 14 are started simultaneously to drive the control rod 804 to rotate. Since the control rod 804 is threadedly connected to the moving rod 802 and the end plate 2 restricts the direction of movement of the moving rod 802, the moving rod 802 is driven to move horizontally forward, pushing the rotating rod 801 forward. The guide rod 13 moves synchronously. Since one end of the limiting band 805 is fixedly connected to the inside of the fixed frame 1, when the auxiliary wheel 803 moves with the rotating rod 801 and the rotating rod rotates, the support rod 806 rotates, and the limiting band 805 gradually loosens. Thus, the extended part of the limiting band 805 fits along the side of the increased clamping piece, and the limiting band 805 remains taut, thereby providing sufficient limiting protection for the side of the plate 7.
