Description

Technical Field

[0001] This utility model relates to Joule thermoelectric electrodes, and more particularly to a Joule hot water cold electrode. Background Technology

[0002] Existing flash Joule thermal shock technology solutions: The high-temperature thermal shock device mainly consists of four parts: a DC power supply, a heating reaction chamber, a spectrometer, and a vacuum pump. Specifically, the sample material is connected to copper sheets via conductive silver paste and fixed to a glass support. The copper sheets at both ends of the sample are connected to the DC power supply. Turning on the power supply will trigger a high-temperature thermal shock.

[0003] The disadvantages of existing technologies are as follows:

[0004] (1) Traditional Joule heating clamps can only clamp a specific material, such as carbon cloth / carbon paper / carbon felt, or only graphite boats. They cannot enable the electrode to clamp carbon cloth / carbon paper / carbon felt / graphite boat / quartz tube and other materials at the same time, and cannot achieve the goal of heating solids, liquids and gases with one electrode.

[0005] (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 copper fixture has high resistance and generates a lot of heat, causing the fixture to burn out. Therefore, the service life is not long and obvious burning oxidation and discoloration are easy to occur.

[0006] (3) Existing electrodes cannot withstand high temperatures for extended periods;

[0007] (4) The electrodes are separate, which can easily lead to different heating rates on both sides. The temperature imbalance on both sides of the electrodes has a significant impact on the material properties and uniformity. Summary of the Invention

[0040] The design of the circulation path of the cooling medium and the flow path of the current simultaneously meets the requirements of cooling and Joule heating.

[0041] The embodiments of this utility model will be further described below with reference to several examples.

[0042] Example 1

[0043] like Figures 1-4 A Joule hot water cooled electrode includes a first conductive clamp 1 and a first conductive water-cooled part 2 fitted to the first conductive clamp 1. The first conductive water-cooled part 2 is formed by stacking a first water-cooled plate 2-1, a second water-cooled plate 2-2, a third water-cooled plate 2-3, and a fourth water-cooled plate 2-4 from top to bottom. There is a through hole between two adjacent conductive water-cooled plates for connecting the upper and lower conductive water-cooled plates. The first through hole 2-1-1 of the first water-cooled plate 2-1 is connected to the first conductive pipe 3, and the fourth through hole 2-4-1 of the fourth water-cooled plate 2-4 is connected to the second conductive pipe 4.

[0045] A carrier 11 for supporting the 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 into 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 a second through groove 7-2 for avoiding the third conductive pipe 6. The second conductive clamp 7 has a third groove 1-3 mirror-image of the first groove 1-1, and a fourth groove 7-3 mirror-image of the second groove 7-1. When the first groove 1-1 or the second groove 7-1 is damaged by high temperature, the first conductive clamp 1 and the second conductive clamp 7 can be interchanged, thereby using the third groove 1-3 and the fourth groove 7-3 to install the carrier 11, extending the service life of the clamp. In this embodiment, the cross-section of the first groove 1-1, the second groove 7-1, the third groove 1-3 and the fourth groove 7-3 is square, and there is one of each.

[0047] It also includes a driver 13 for driving the cooling medium, which is connected to the second conductive pipe 4 and the fourth conductive pipe 9 respectively through an insulating interface;

[0048] It also includes a power supply 14, one end of which is connected to the second conductive pipe 4 via the first wire 5, and the other end is connected to the fourth conductive pipe 9 via the second wire 10.

[0049] In this embodiment, in order to make the cooling medium flow a longer distance, the through holes of two adjacent water-cooling plates are respectively set at opposite ends, that is, the distance between the first through hole 2-1-1 and the second through hole 2-2-1, the second through hole 2-2-1 and the third through hole 2-3-1, and the third through hole 2-3-1 and the fourth through hole 2-4-1 are all set at the farthest positions.

[0050] In this embodiment, both the insulating interfaces at the insulating interfaces 12 and the two ends of the driver 13 are made of ceramic.

[0051] In this embodiment, the cooling medium used is deionized water.

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, and the shapes of the two ends of the graphite rod are also arc-shaped. In some embodiments, they can also be square, triangular or U-shaped.

[0054] Example 3

[0055] like Figure 6 This embodiment is basically the same as embodiment 1, except that the internal structure of the first conductive water-cooling part 1 and the second conductive water-cooling part 7 is formed by metal 3D printing, the carrier 11 used is a conductive quartz tube, and the gas used as the heated material is filled in the conductive quartz tube. In this embodiment, the cross-section of the first groove 1-1 and the second groove 7-1 is an arc-shaped through groove, and there is no third groove 1-3 and fourth groove 7-3.

[0056] Example 4,

[0057] 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.

[0058] In some embodiments, more of the first groove 1-1, the second groove 7-1, the third groove 1-3, and the fourth groove 7-3 may be provided as needed.

[0059] In some embodiments, a water tank for storing water may be provided in the circuit through which the cooling medium flows, fins for dissipating heat from the cooling medium may be added, and fans for generating airflow to remove heat from the heat dissipation fins may be added to the heat dissipation fins.
