フィン５２ａを介して外部雰囲気に放熱している。2. Description of the Related Art Conventionally, a power regulator is generally used for controlling power to a heater, for example. Such a power conditioner includes a thyristor as a switching element,
The amount of power supplied to the heater is adjusted by controlling the phase angle by the thyristor. However, thyristors generate large amounts of heat due to power loss. Therefore, a heat sink is provided to radiate the heat generated by the thyristor to the atmosphere outside the power conditioner. Here, FIGS. 6 and 7 show a conventional power conditioner. The power regulator 5 includes a heat sink 52 on the rear side of a housing 51, and a thyristor 53 is mounted directly on the heat sink 52. The radiator plate 52 is provided with a plurality of radiator fins 52a, and radiates the heat transmitted to the radiator plate 52 to the outside atmosphere via the radiator fins 52a.
【０００３】サイリスタ５３を放熱板５２に接触させる
理由は、電力調整器５に必須のサイリスタ５３は発熱部
品であり、発熱を放熱板５２から放熱させて電力調整器
内部の温度上昇を極力抑える必要性があるからである。The reason that the thyristor 53 is brought into contact with the radiator plate 52 is that the thyristor 53, which is indispensable for the power regulator 5, is a heat-generating component, and it is necessary to radiate heat from the radiator plate 52 to minimize the temperature rise inside the power regulator. Because there is a nature.

い、これらの小型化・薄型化の要請に反する。However, in the conventional power regulator 5, the heat radiating plate 52 is disposed on the back of the power regulator 5 as shown in FIG. However, it can be arranged only on the heat sink surface as shown in FIG. In the configuration in which the thyristor 53 is arranged in this manner, the head of the thyristor 53 faces the front side of the power regulator, and since it is necessary to connect an electric wire to the connection terminal of this head, the depth of the power regulator is limited to some extent. I have no choice. When the power regulator 5 having such a depth is provided in a control panel or a power panel (not shown), the control panel or the power panel itself becomes large, which is against the demand for downsizing and thinning.
【０００５】また、放熱板５２を電力調整器５の背面部

上の制約がある以上、放熱面積を稼ぐことができない。Further, since the heat radiating plate 52 is provided only on the back surface of the power regulator 5, there is a restriction on the external dimensions of the whole power regulator, so that a heat radiation area cannot be increased.

A power regulator, wherein a heat radiating plate as a main body case is provided on at least two continuous surfaces of the power regulator main body case.

コストが下がる。The heat radiating plate provided on at least two surfaces of the case can also be used as a part of the main body case. This alleviates restrictions when designing the arrangement of heat-generating electric components (such as thyristors) provided inside the case and attached to the heat sink. Specifically, the depth is reduced without increasing the width of the power regulator itself. As described above, the heat radiation effect can be enhanced while the body size of the power regulator itself is reduced, and as a result, the configuration of the power regulator body is simplified and the cost is reduced.
【００１０】また、電力調整器自体の小型化を図ること

ことができる。Further, since at least two surfaces of the power conditioner main body case are formed of a rigid heat radiating plate, it is possible to protect the electric components housed in the power conditioner main body.
In particular, the built-in electric components can be protected in a state before the power conditioner is installed (for example, during transportation of the power conditioner).

に行うことも可能となる。Further, since at least two surfaces of the case are formed of a rigid heat radiating plate, the strength of the housing constituting the other surface of the power conditioner main body case is not required as much as the conventional case.
For this reason, the housing is made thinner to facilitate processing of air holes and the like, and more air holes are formed in the housing than conventional power regulators to more efficiently ventilate inside and outside the power regulator. It is also possible.

It is provided on the side surface, and is characterized in that the thickness of one surface is smaller than the thickness of the other surface of the heat sink.

の間隙に効率的に放熱することができる。Since the side of the main body case is thinned and this portion mainly serves as a heat transfer plate, when a plurality of power regulators are installed in parallel on a control panel or a power panel, the depth can be reduced. It contributes to making control panels and power panels smaller and thinner. In addition, since the side surface of the main body case also plays a role of a heat radiator plate, the contact area with the external atmosphere can be made much larger than that of the conventional power regulator, and the heat radiation effect is enhanced. In particular, since the side of the power regulator is also used as a heat radiator, when multiple power regulators are installed in parallel on a control panel or power panel, these power regulators that were not used in the conventional power regulator The heat can be efficiently radiated to the gap between the containers.

However, the unevenness 12a on the surface of the heat transfer section has a certain degree of heat dissipation effect, and thus also plays a secondary role as a heat sink. The plurality of radiating fins 11a formed on the heat radiating portion 11 are configured to efficiently radiate the heat transmitted from the heat transfer portion 12 to the external atmosphere by increasing the contact area with the external atmosphere.

The degree of freedom of the layout of the thyristor 14 increases. In particular, when the thyristor 14 is mounted on the heat transfer plate 12, the depth of the power regulator 1 is reduced, which contributes to downsizing of the power regulator itself. In addition, since the internal space of the control panel and power panel is considerably occupied by the power regulator, it is possible to make the control panel and power panel smaller and thinner by reducing the size of the power regulator itself.
