Abstract
Description
Technical Field
[0001] The invention relates to a Joule hot electrode, in particular to a Joule hot water cooling electrode. Background Art
[0002] Existing flash Joule heating high-temperature shock technology: The high-temperature thermal shock device consists of four main components: a DC power supply, a heated reaction chamber, a spectrometer, and a vacuum pump. Specifically, the sample material is connected to a copper sheet via conductive silver glue and fixed to a glass holder. The copper sheets at both ends of the sample are connected to a DC power supply. Turning on the power triggers the high-temperature thermal shock.
[0003] The shortcomings of the prior art are as follows: (1) Traditional Joule heating fixtures can only clamp a specific material, such as carbon cloth / carbon paper / carbon felt, or can only clamp a graphite boat. It is impossible for the electrode to clamp carbon cloth / carbon paper / carbon felt / graphite boat / quartz tube and other materials at the same time, and it is impossible to achieve that one electrode can heat both solids and liquids and gases; (2) The fixture is made of pure copper or brass. Copper will inevitably oxidize, and copper oxide has poor conductivity, which seriously affects the passage of strong current. In addition, under the action of strong current, the oxide layer of the copper fixture has a large resistance and generates severe heat, causing the fixture to burn out. Therefore, the service life is not long and it is easy to show obvious burnout, oxidation and discoloration. (3) Existing technology electrodes cannot withstand high temperatures for a long time; (4) The electrodes are separated, which easily leads to different heating temperature rise rates on both sides. The temperature imbalance on both sides of the electrode has a great impact on the material properties and uniformity. Summary of the Invention

A through hole for connecting flow channels between the upper and lower conductive water-cooling plates is provided between adjacent two conductive water-cooling plates. A first through hole 2-1-1 of the first water-cooling plate 2-1 is connected to a first conductive pipe 3, and a fourth through hole 2-4-1 of the fourth water-cooling plate 2-4 is connected to a second conductive pipe 4. The invention also includes a second conductive fixture 7, a second conductive water-cooling part 8, a third conductive pipe 9 and a fourth conductive pipe 10 which are mirror-imaged and have the same structure as the first conductive fixture 1, the first conductive water-cooling part 2, the first conductive pipe 3 and the second conductive pipe 4; A carrier 11 for carrying a heated material is installed between the first conductive clamp 1 and the second conductive clamp 7. The first conductive clamp 1 and the second conductive clamp 7 transfer heat to the carrier 11. In this embodiment, a graphite boat is used. The outer surfaces of both ends of the graphite boat are respectively fitted in the first groove 1-1 of the first conductive clamp 1 and the second groove 7-1 of the second conductive clamp 7. Therefore, heat can be quickly transferred to the graphite boat through the first conductive clamp 1 and the second conductive clamp 7; the first conductive clamp 1 also has a first through groove 1-2 for avoiding the first conductive pipe 3, and the first conductive clamp 1 also has a second through groove 7-2 for avoiding the third conductive pipe 6; the first conductive clamp 1 also has a There is a third groove 1-3 that is mirrored with the first groove 1-1, and the second conductive clamp 7 also has a fourth groove 7-3 that is mirrored with the second groove 7-1; when high temperature causes damage to the first groove 1-1 or the second groove 7-1, the first conductive clamp 1 and the second conductive clamp 7 can be interchanged, so that the third groove 1-3 and the fourth groove 7-3 are used to install the carrier 11, thereby extending the service life of the clamp; in this embodiment, the cross-sections of the first groove 1-1, the second groove 7-1, the third groove 1-3 and the fourth groove 7-3 are square, and the number is 1. The shapes of the two ends of the graphite boat are also square. In some embodiments, they can also be arc-shaped, triangular or U-shaped.

[0026] In this embodiment, in order to make the cooling medium flow over a longer distance, the through holes of two adjacent water-cooling plates are respectively arranged at opposite ends, that is, the distance between the first through hole 2-1-1 and the second through hole 2-2-1, the distance between the second through hole 2-2-1 and the third through hole 2-3-1, and the distance between the third through hole 2-3-1 and the fourth through hole 2-4-1 are all arranged at the farthest position.

[0029] Example 2 like Figure 5 This embodiment is essentially the same as Example 1, differing in that the internal structures of the first and second conductive water-cooling sections 1 and 7 are integrated using metal 3D printing. The carrier 11 is a graphite rod, with carbon fiber, the heated material, wrapped around the rod. In this embodiment, the cross-sections of the first groove 1-1, the second groove 7-1, the third groove 1-3, and the fourth groove 7-3 are arc-shaped, as are the ends of the graphite rod. In some embodiments, these shapes can also be square, triangular, or U-shaped.
[0030] Example 3 like Figure 6 This embodiment is basically the same as embodiment 1, except that the internal structures of the first conductive water-cooling part 1 and the second conductive water-cooling part 7 are formed by metal 3D printing, and the carrier 11 used is a conductive quartz tube. The gas as the heated material is filled in the conductive quartz tube. In this embodiment, the cross-sections of the first groove 1-1 and the second groove 7-1 are arc-shaped through grooves, and there are no third grooves 1-3 and fourth grooves 7-3.
[0031] Example 4, like Figure 7 This embodiment is basically the same as embodiment 1, except that the number of the first groove 1-1, the second groove 7-1, the third groove 1-3 and the fourth groove 7-3 are all 2.
[0032] In some embodiments, more first grooves 1 - 1 , second grooves 7 - 1 , third grooves 1 - 3 and fourth grooves 7 - 3 may be provided as needed.
[0033] In some embodiments, a water storage tank may be provided on the circuit through which the cooling medium flows, fins may be added for dissipating heat from the cooling medium, and fans may be added to the heat dissipating fins for generating airflow to remove heat from the heat dissipating fins.
