A cavity 2 with an open end and a closed end is formed in the current-conducting rod 1, and a front end cover 12 is installed on the port of the cavity 2 of the current-conducting rod 1 and is connected with the cavity in a sealing mode. It should be noted that, the sealing connection can be selectively bonded, the front end cover 12 covers the opening of the cavity 2, and then the sealant is sealed in the gap between the front end cover 12 and the conductive rod 1; the sealing connection can also be a thread sealing connection, the front end cover 12 is provided with an external thread, the inside of the current conducting rod 1 is correspondingly provided with an internal thread, and the two threads are matched and sealed. The sealing connection avoids the leakage of cooling medium, ensures that the current-conducting rod 1 is continuously cooled, ensures the normal work of the current-conducting rod 1, and greatly improves the safety of the current-conducting rod 1. The conductive rod 1 works at normal temperature, and has longer service life compared with the conductive rod working in a high-temperature environment.
During installation, the fluid input structure 3 and the fluid output structure 4 firstly penetrate through the preformed hole in the front end cover 12, glue is sealed at the gap point of the preformed hole, then the turbulent flow structure 5 and the buffer structure 7 are installed, and the conducting rod 1 and the front end cover 12 are installed in a sealing connection mode.
The fluid inlet structure 3 corresponds to a liquid inlet pipe, and the fluid outlet structure 4 corresponds to a liquid outlet pipe. One end of the fluid input structure 3 and the fluid output structure 4 is inserted into the cavity 2 through the front end cap 12. When the contact bar 1 is horizontally placed as shown in fig. 1, or when the cavity 2 of the contact bar 1 is opened upward and sealed downward, the fluid inlet structure 3 is inserted deeper and sealed near the cavity 2. Whereas the fluid output structure 4 is inserted less deeply, close to the cavity 2 opening. This structure is favorable to filling cavity 2 with the cooling medium that flows in through fluid input structure 3, lets the conducting rod 1 and the abundant heat transfer of cooling medium, reaches the effect that lets the conducting rod 1 cool down, and then the cooling medium flows out from fluid output structure 4 again.

Because the temperature of the cooling medium close to the inner wall of the current-conducting rod 1 is higher, and the temperature of the cooling medium far away from the inner wall of the current-conducting rod 1 is lower, the cooling water flows out and becomes disordered, and the cooling water with different temperatures is uniformly mixed, so that the cooling effect is better.
In one implementation of the embodiment of the present invention, a micro-pump 13 is provided on the fluid input structure 3. The micro pump 13 has small volume, does not occupy too large space, and provides power for the circulating heat exchange of the cooling medium. The power generated by the micro-pump 13 can meet the requirement because the cavity 2 of the heat conducting rod 1 has small volume and does not need the cooling medium to have fast flow rate. The invention has small requirement on power, the power consumption of the micro pump 13 is especially low, and energy waste can not be caused. A micro-pump 13 is mounted on the fluid input structure 3 between the conductive rod 1 and the cooling means.
Example 2
Referring to fig. 5, the structure of this embodiment is substantially the same as that of embodiment 1, and the only difference is that the spoiler structure 5 is replaced by a spiral piece.
In the embodiment of the present invention, the turbulent flow structure 5 includes a spiral piece, and the spiral piece is sleeved on the circumferential surface of the fluid input structure 3. The spiral piece is a circle of axially extending rotary piece, the axis of the spiral piece is provided with an axis hole, and the spiral piece is sleeved on the outer surface of the fluid input structure 3 through the axis hole and is bonded and fixed by waterproof glue. Because the cooling medium temperature that is close to the inner wall of conducting rod 1 is higher, and the cooling medium temperature that keeps away from the inner wall of conducting rod 1 is lower, becomes disorderly when the cooling water flows through the flight, and the cooling water misce bene of different temperatures for the cooling effect is better.
In summary, the invention provides a cooling electrode for a high-temperature electrical heating experiment, which adopts a conductive rod 1, wherein the conductive rod 1 is provided with a cavity 2, one end of the cavity 2 is open and the other end is sealed, the opening of the cavity 2 is connected with a front end cover 12, a fluid input structure 3 and a fluid output structure 4 are inserted into the cavity 2, the fluid input structure 3 is connected with a turbulent flow structure 5, the inner surface of the conductive rod 1 is provided with an insulating structure 6, the end part of the fluid input structure 3 is fixedly connected with a buffer structure 7, the fluid input structure 3 and the fluid output structure 4 are both externally connected with a cooling device, the cooling device stores a cooling medium, and the cooling medium impacts on the buffer structure 7 when flowing out from the port. Through cooling medium, take away the heat on the conducting rod 1, to the cooling of conducting rod 1, have the advantage that improves the security of conducting rod 1, increase of service life.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
