Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate heat exchanger technology, and more specifically, to a fully detachable plate heat exchanger. Background Technology
[0002] Plate heat exchangers are composed of stamped, textured stainless steel plates. The textures between two adjacent plates are aligned at 180 degrees, creating staggered contact points. These contact points are then joined by vacuum welding, forming the high-pressure, staggered flow structure of the plate heat exchanger. This staggered flow structure generates strong turbulence in the hot and cold fluids within the heat exchanger, achieving a high heat transfer efficiency. The plate heat exchanger consists of a set of corrugated metal plates with four corner holes for the passage of the two heat transfer fluids. The metal plates are mounted within a frame with a fixed plate and a movable clamping plate on one side, and are clamped together with bolts.
[0003] The plates are fitted with sealing gaskets to seal the fluid channels and guide the fluid to flow alternately into their respective channels, forming heat exchange. The fluid flow rate, physical properties, pressure drop, and temperature difference determine the number and size of the plates. The metal plates and movable pressure plates are suspended by the upper guide rod and positioned by the lower guide rod, while the rod ends are fixed to the support columns. The overall structure is easy to disassemble, allowing all the metal plates to be removed one by one.
[0004] However, most plate heat exchangers are currently vertical plates. When it is necessary to increase the fluid flow path, the size of the metal plate can only be increased, which will lead to a larger overall structural size, increased difficulty in loading and unloading, and is not conducive to installation and use. Utility Model Content

A pressing plate is slidably installed between the L-shaped frame and the base plate. A second corrugated abutment is fixedly installed on the left side of the pressing plate. A continuous contact corrugated heat exchange plate is pressed and fixed between the opposite sides of the first and second corrugated abutments. A flow guiding sealing ring is provided between two adjacent corrugated heat exchange plates. The corrugated heat exchange plate has four flow guiding holes that correspond to the four through holes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0022] Please see Figure 1-4 In this utility model, a fully detachable rolled plate heat exchanger includes a base plate 1. A positioning plate 2 is fixedly connected to the top left side of the base plate 1. The positioning plate 2 has four through holes 3. A first corrugated abutment block 4 is fixedly installed on the right side of the positioning plate 2. An L-shaped frame 5 is detachably connected between the base plate 1 and the positioning plate 2 by bolts. An extrusion plate 6 is slidably installed between the L-shaped frame 5 and the base plate 1. A second corrugated abutment block 7 is fixedly installed on the left side of the extrusion plate 6. A corrugated heat exchange plate 8 with continuous contact and fit is extruded and fixed between the opposite sides of the first corrugated abutment block 4 and the second corrugated abutment block 7. A flow guiding sealing ring 9 is provided between two adjacent corrugated heat exchange plates 8. Four flow guiding holes 10 are opened on the corrugated heat exchange plate 8, which correspond to the four through holes 3 respectively. The flow guiding sealing ring 9 vertically isolates the flow guiding holes 10 into two independent channels on both sides. Two sets of locking parts 11 are installed between the two outer sides of the extrusion plate 6.
[0023] In this invention, the substrate 1 serves as the main body of the device. During use, the four through holes 3 are vertically connected in pairs to the hot and cold media, allowing the hot and cold media to enter from the top and exit from the bottom through the two vertical through holes 3 on each side. When the hot and cold media enter the heat exchange structure composed of the corrugated heat exchange plates 8, they flow independently through both sides of the corrugated heat exchange plates 8. Heat is conducted and exchanged through the corrugated heat exchange plates 8. Due to the curved design of the corrugated heat exchange plates 8, the flow path of the hot and cold media is increased compared to a straight plate, increasing the heat transfer time and achieving better heat exchange. This allows the device of the same height to achieve a longer length. The flow path is clear, and during disassembly, the locking part 11 is removed to release the positioning of the extrusion plate 6. Then, the bolts are turned to remove the L-shaped frame 5, thus completely removing the external positioning structure of the corrugated heat exchange plate 8. This achieves the advantages of increasing the flow path without increasing the height and volume of the device by using a curved metal plate design, improving performance, and facilitating disassembly and installation. This solves the problem in the prior art where the plates are generally vertical straight plates, and when a fluid flow path needs to be increased, the size of the metal plate can only be increased, which leads to a larger overall structural size, increased difficulty in loading and unloading, and is not conducive to installation and use.
[0024] Please see Figure 1 and Figure 4 The locking component 11 includes a long screw 111, a locking nut 112, and an ear block 113. One end of the long screw 111 is fixedly connected to the positioning plate 2, and the other end of the long screw 111 passes through and slides to the right side of the ear block 113. The outer side of the ear block 113 is fixedly connected to the side of the extrusion plate 6. The internal thread of the locking nut 112 is connected to the outer side of the long screw 111 and the extrusion plate 6 is locked by the ear block 113.
[0025] In this utility model, by rotating the locking nut 112, the lug 113 is squeezed along the long screw 111, thereby driving the extrusion plate 6 to press and position the corrugated heat exchange plate 8. Conversely, it can be removed. The operation is convenient and the loading and unloading is easy.
[0026] Please see Figure 3 Among them, the front view of the corrugated heat exchange plate 8 is an S-shaped curve.
[0027] In this invention, the front view of the corrugated heat exchange plate 8 is S-shaped, which makes it easier for the corrugated heat exchange plates 8 to fit together, resulting in better sealing after compression, and also increasing the flow path of the hot and cold media.
[0028] Please see Figure 1 and Figure 3 The corrugated heat exchange plate 8 has a limiting groove 81 at both the top and bottom. The horizontal section of the L-shaped frame 5 is slidably connected to the inside of the limiting groove 81 at the top. A guide rail 12 that cooperates with the limiting groove 81 at the bottom is fixedly connected to the base plate 1.
[0029] In this utility model, the positioning of the corrugated heat exchange plate 8 with the L-shaped frame 5 and the guide rail 12 is more precise and stable by the limiting slide groove 81, which makes the installation of the compression type and the alignment of the corrugated heat exchange plate 8 more accurate.
[0030] Please see Figure 2 The positioning plate 2 is fixedly installed with four sets of connecting screws 21 that cooperate with the four through holes 3. Each set of connecting screws 21 is located in a ring on the outside of the four through holes 3.
[0031] In this invention, the connecting screw 21 facilitates the connection of the through hole 3 to the external hot and cold medium pipeline, making the operation convenient.
[0032] Please see Figure 4 Among them, the top and bottom of the extrusion plate 6 are respectively provided with guide grooves 61 that cooperate with the L-shaped frame 5 and the guide rail 12.
[0033] In this invention, the guide groove 61 makes the connection between the extrusion plate 6, the L-shaped frame 5, and the guide rail 12 more stable, and also makes disassembly and movement more convenient.
[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
