Embodiment 1

[0042] RF cables are mainly used between the RF source and the matcher, and between the matcher and the load. There is a stable match between the RF source and the matcher. The loss in the transmission process is very small, and the heat generated is very small. Auxiliary device for heat dissipation. Due to the diversity and uncontrollability of the load, the matching between the matcher and the load is unstable, so the transmission loss between the matcher and the load is very large, and a lot of heat is generated at the same time, and the heat conduction of the RF cable itself cannot be effective. The heat is transferred out, causing the temperature of the cable to rise. It needs the assistance of an efficient heat dissipation device to reduce the temperature of the RF cable in time. Axial heat convection is a very suitable and efficient heat transfer method for cables. Therefore, this device Take this approach.

[0043] This embodiment provides an axial heat convection coo...

Embodiment 2

[0058] Such as Figure 10 As shown, this embodiment is substantially the same as Embodiment 1, except that a through hole is provided on the outside of the first conduit 4, and a T-shaped joint 5 is sleeved on the outside of the through hole, and the input end of the T-shaped joint 5 faces the through hole.

[0059] Such as Figure 11 As shown, it is a structural schematic diagram in which a plurality of through holes and a T-shaped joint 5 are provided on the outside of the first conduit 4 .

Abstract

The invention relates to an axial thermal convection cooling device for a radio frequency cable. The device is used for cooling the radio frequency cable and comprises a trapezoidal joint, a first guide pipe, a T-shaped joint, a bracket, a second guide pipe and cooling medium input equipment, the radio frequency cable is installed in the first guide pipe, and the first guide pipe supports the radio frequency cable through a support. The first guide pipe is of a sectional structure, a T-shaped connector is connected between every two adjacent sections of the first guide pipe, and the T-shaped connectors are further connected with cooling medium input equipment through second guide pipes; trapezoidal connectors are arranged at the two ends of the whole first guide pipe and provided with through holes allowing radio frequency cables to penetrate through, and the cooling medium input device is used for inputting convection media. Compared with the prior art, axial heat convection heat dissipation cooling of the radio frequency cable is achieved, cooling of the radio frequency cable is accelerated, and a radio frequency power supply can stably output in a normal high-power working state.

Description

technical field [0001] The invention relates to the technical field of radio frequency cable heat dissipation, in particular to an axial heat convection cooling device for radio frequency cables. Background technique [0002] When the electromagnetic signal transmission device transmits high-power current signals, the transmission device will absorb part of the electromagnetic energy and convert it into heat energy, resulting in loss; if the radio frequency equipment and the load cannot achieve a good match, the electromagnetic signal will be more on the transmission cable. Repeated round-trips will cause the electromagnetic signal to be absorbed by the transmission cable multiple times, thereby transforming into more heat energy, causing the transmission cable and the connector to become hot, and the connection device to loosen, which will eventually lead to damage to the radio frequency equipment. [0003] The RF power supply has the characteristics of high frequency, and ...
