ない、電力の放出を良好に行なうことが重要となる。In electrical circuits, there is a method that utilizes the resistance of a material with high electrical resistance as a means of controlling the amount of electricity that is applied to the electrical circuit. For example, a spot detection circuit may be protected by converting surplus electricity into thermal energy using a resistor. The resistor device used in such a case is a sheathed heater type in which a resistor 3 is provided inside an outer tube 1 via an insulator 2, as shown in FIG.
Surplus power is consumed by energizing the resistor 3 from the electric circuit and generating heat. Therefore, in this resistor device, an external 9 is used to sufficiently cool the heat generated from the resistor 3. It is important to blow air efficiently to effectively dissipate heat and dissipate power well.

良好に行なえないという問題がある。Therefore, a configuration is adopted that increases the heat dissipation area. However, in the resistor device, since the resistor 3 is surrounded by the outer tube 1 and the insulator 3, the amount of heat generated by the resistor 3 is limited to the area near the resistor inside the outer tube 1. For example, resistor 3
If it is in the form of a coil, it will accumulate in the inner part surrounded by the coil. Therefore, the temperature of the portion inside the outer tube 1 near the resistor is not the lowest, and the heat of the resistor 3 that is conducted through the outer tube 1 and the insulator 2 and released to the outside is reduced. Therefore, in the conventional structure, the resistor 3. There is a problem in that the heat of the resistor 3 is not partially transmitted to the radiation fins 4 provided around the outer tube 1, and therefore the heat of the resistor 3 cannot be efficiently radiated to the outside, and surplus power cannot be properly radiated.

This resistor J3 is provided along the axial direction inside the outer tube 11 and is embedded and supported in the insulator 12. Both ends of the resistor 130 are connected to terminals 141'' protruding from the outer side of the circumferential wall at both ends of the outer tube 11. Inside the outer tube 11, the inner portion of the coil of the resistor 13 is connected to a terminal 141'' of the resistor 13.

The inner part of the coil, that is, the part near the resistor, is the resistor 1.
The amount of heat generated in step 3 is inhibited by the insulator 12 and is not conducted to the outside (it accumulates at the point where the temperature is highest in the entire resistor device. Therefore, the fluid pipe 15 , the resistor 13 is located inside the outer tube 11, surrounded by the resistor 13, where much of the heat of the resistor 13 accumulates and becomes high temperature. is a sealing material that seals both ends of the outer tube 11.

Both ends of the fluid pipe 15 are opened to the atmosphere. When surplus power is generated in the electric circuit and the resistor 15 is energized, the resistor 15 generates heat. The heat of resistor 13 is transferred to resistor 1
5. Heat is conducted from the periphery to the fluid pipe 15 through the insulator 12 in the inner portion of the fluid pipe 15. In addition, the fluid pipe 15
Air from the outside can flow inside. For this reason, the fluid pipe 15
is cooled and heat is radiated by the air passing through its interior. Here, in the inner part of the coil of the resistor 13, that is, the part near the resistor, as described above (= Since a large amount of heat of the resistor 13 is accumulated, a large amount of accumulated heat is transferred to the fluid pipe 15. At this time, there is an external hoof inside the body canal 15.

。By healing the body, the heat transferred to the body can be efficiently removed. Further, a part of the heat generated in the resistor 13 is conducted to the outer tube 1 through the insulator 12 on the outer side of the coil of the resistor 13, and is transmitted to the outer tube 1. Heat is radiated from the outer tube 11 by external air. Therefore, the resistor 13
Since heat exchange is performed by fluids on the inside and outside of the tube, it is possible to obtain a remarkable heat dissipation effect compared to the conventional method.
