TECHNICAL FIELD OF THE INVENTION
[0002] The present invention relates to heat radiation of a heating cable, for example, a cable such as a semi-rigid cable, which is intended for relatively high output.
[Prior art]
When high power is used in a high-frequency device using a semi-rigid cable for connecting between high-frequency circuits, a semi-rigid cable having a large diameter is used to improve the heat radiation effect. However, as the semi-rigid cable becomes thicker, the cost increases and the processing becomes difficult. If a semi-rigid cable having a small diameter is used for cost reduction, the temperature of the cable increases. Also, it has been difficult to use a small-diameter semi-rigid cable and directly blow air from the cooling fan of the apparatus to the cable to cool the entire semi-rigid cable over the entire apparatus.
[0003]
Further, as another conventional technique, there is a structure for processing a surplus length of a cable (for example, see Patent Document 1).
[0004]

[Problems to be solved by the invention]
An object of the present invention is to cool a heating cable which is a problem of the prior art.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention described in claim 1 of the present invention relates to a heating cable for high output, in which fins are directly attached to an external conductor and heat generated from the heating cable is blown by a cooling fan. It is characterized by cooling.
[0007]
Further, the invention according to claim 2 is characterized in that, in the heating cable intended for high output, the heating cable and the heat sink are in close contact with each other, and the air from the cooling fan is passed between the fins of the heat sink for cooling. I do.
[0008]
Further, the invention according to claim 3 is characterized in that, in a heating cable intended for high output, the heating cable is fixed to and contacted with a heat sink, and is cooled by blowing air from a cooling fan.
[0009]
Configuration and Function of the Invention
In order to achieve the above object, according to the present invention, as shown in FIG. Structure.
Specifically, a plurality of fins 2 are radially attached to the outer peripheral surface of the heating cable 1. Further, though not shown, air from a cooling fan is passed through the heat generating cable 1 between the fins 2 to be air-cooled. Each fin 2 is attached to the outer peripheral surface of the heating cable 1 by welding, bonding, or the like.
With such a configuration, the heating cable 1 can be cooled even if the amount of heat generated from the heating cable 1 increases.
[0010]
Further, as shown in FIG. 2, a groove 4 is provided in the heat sink 3 for cooling the entire device in conformity with the shape of the heating cable 1, and a part or the whole of the surface (outer periphery) of the heat sink 3 and the heating cable 1 are brought into close contact. The fins of the heat sink 3 are cooled by blowing air from a cooling fan (not shown).
In this way, by further providing a groove in the heat sink 3 and bringing the heating cable 1 into close contact with the groove, it is possible to obtain a further heat radiation effect.
[0011]
Next, another example in which the heat sink 3 is cooled by blowing air from a cooling fan is shown in FIG. As shown in the figure, a fixing device 5 for bringing the heat generating cable 1 into contact with the heat sink 3 may be combined to bring the heat generating cable 1 into contact with the heat sink 3. The fixing device 5 in this case may be assembled with an adhesive or the like, or may be assembled by fastening the whole with a screw.
[0012]
With such a configuration, it is possible to realize a structure in which the heat generation of the heat generation cable is improved even when the heat generation amount of the heat generation cable increases.
[0013]
【The invention's effect】
By practicing the present invention, a fin is directly attached to the outer conductor of the heat generating cable, a structure for blowing air from the cooling fan to the fin, the heat generating cable is brought into contact with the heat sink, and the heat generating cable is connected to the heat sink by using a fixing device. The close contact makes it possible to effectively cool the heat from the heat-generating cable, and even a relatively thin and inexpensive cable to cool the heat, thereby preventing a thermal accident. In addition, by tightly fixing the heat generating cable to the heat sink, the cable can be fixed and the RF characteristics can be stabilized.
