Description

Technical Field

[0001] This utility model relates to the field of graphite technology, and in particular to a graphite block for enhanced turbulent heat transfer. Background Technology

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid. It is chemically stable, corrosion-resistant, and does not readily react with acids, alkalis, or other reagents. Natural graphite comes from graphite deposits, but artificial graphite can also be made from petroleum coke, pitch coke, and other raw materials through a series of processing steps.

[0003] An existing enhanced turbulent heat transfer graphite block (publication number: CN110553529A) has at least the following drawbacks: the device increases the heat exchange area by using a concave-convex spiral inner wall, but the structure is simple because it only sets a concave-convex spiral inner wall in the channel. When liquid or gas passes through the channel, the flow rate is relatively slow, which affects the heat exchange effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a graphite block for enhanced turbulent heat transfer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A graphite block for enhanced turbulent heat transfer includes a graphite body and a horizontal protective strip. The upper end of the graphite body has vertical holes that are evenly distributed on the graphite body. The inner wall of the vertical holes is fixedly provided with concave and convex threads. The side wall of the graphite body has horizontal holes. The horizontal protective strip is fixedly installed on the side of the graphite body away from the horizontal holes. An installation ring is provided inside the vertical holes. A connecting rod is installed at the lower end of the installation ring. A spiral baffle is fixedly provided on the connecting rod.

[0007] As a further embodiment of this utility model, a fixing block is provided on the inner side of the mounting ring, and an inclined block is fixedly provided between the fixing block and the inner wall of the mounting ring. The top end of the connecting rod is fixedly connected to the fixing block, and a connecting rod 2 is provided on one side of the connecting rod.

[0008] As a further embodiment of this utility model, the top end of the second connecting rod is fixedly connected to the fixing block, and the outer wall of the first mounting ring is fixedly installed with a locking block, which is distributed at equal intervals on the outer wall of the first mounting ring.

[0009] As a further embodiment of this utility model, the card block is fitted into the inner wall of the vertical hole, and the bottom end of the connecting rod is fixedly installed with an installation ring.

[0010] As a further embodiment of this utility model, the spiral baffle is fixedly connected to the second connecting rod, and a metal fiber sheet is fixedly disposed on the outside of the graphite body.

[0011] As a further embodiment of this utility model, the metal fiber sheets are distributed at equal intervals on the graphite body, the metal fiber sheets are fixedly connected to the graphite body, and a vertical protective strip is fixedly installed on the horizontal protective strip.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The graphite body has vertical and horizontal holes distributed at equal intervals, which are arranged in a crisscross pattern while remaining independent of each other. First, the porosity of several metal fiber sheets is used to enhance the heat transfer on the surface of the graphite body. The inner walls of the vertical and horizontal holes are provided with concave and convex threads. The spiral shape of the concave and convex threads causes turbulence in the flow of liquid or gas through the channels, thereby accelerating heat transfer. Furthermore, spiral baffles are set inside the vertical and horizontal holes to increase the flow rate of liquid or gas, thereby further improving heat exchange efficiency and reducing fouling. Finally, the vertical slots and horizontal protective strips are interlocked and fixed to prevent the graphite body from being deformed by compression, thus enhancing the performance of the graphite body.

[0023] In use, vertical holes 102 and horizontal holes 103 are equally spaced on the graphite body 1, so that the vertical holes 102 and horizontal holes 103 are arranged in a cross pattern while remaining independent of each other. First, the porosity of several metal fiber sheets 2 is used to enhance the heat transfer on the surface of the graphite body 1. The inner walls of the vertical holes 102 and horizontal holes 103 are provided with concave and convex threads 101. Then, the spiral shape of the concave and convex threads 101 causes disturbance to the liquid or gas during the flow through the channels, thereby accelerating the heat transfer. Furthermore, spiral baffles 104 are provided inside the vertical holes 102 and horizontal holes 103. The spiral baffles 104 increase the flow rate of the liquid or gas, thereby further improving the heat exchange efficiency and reducing the formation of fouling. Finally, the vertical slots 3 and the horizontal protective strips 301 are interlocked and fixed to prevent the graphite body 1 from being deformed by compression, thereby enhancing the performance of the graphite body 1.

[0027] In use, the spiral baffle 104 is installed in the slot by the mounting ring 203 and the locking block 202, which reduces the formation of dirt, makes it easier to flush the dirt out of the slot, and facilitates the flow of liquid or gas.

[0028] In this embodiment, the locking block 202 is fitted into the inner wall of the vertical hole 102, and the bottom end of the connecting rod 106 is fixedly installed with the mounting ring 302.

[0033] In use, the vertical protective strip 301 and the horizontal protective strip 3 are made of high-temperature resistant rubber. The horizontal protective strip 3 and the vertical protective strip 301 are interlocked to enhance the protection of the graphite body 1 and prevent the graphite body 1 from being squeezed and deformed.

[0034] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: Vertical holes 102 and horizontal holes 103 are provided on the graphite body 1 at equal intervals, so that the vertical holes 102 and horizontal holes 103 are arranged in a cross pattern while remaining independent of each other. First, the porosity of several metal fiber sheets 2 is used to enhance the heat transfer on the surface of the graphite body 1. The inner walls of the vertical holes 102 and horizontal holes 103 are provided with concave and convex threads 101. Then, the spiral shape of the concave and convex threads 101 is used to cause disturbance in the flow of liquid or gas through the channels, thereby accelerating the heat transfer. Furthermore, spiral baffles 104 are provided inside the vertical holes 102 and horizontal holes 103. The flow rate of liquid or gas is increased by the spiral baffles 104, thereby further improving the heat exchange efficiency and reducing the formation of fouling.
