りに電波障害を被る恐れがあった。Since the water-cooled resistor disclosed in the above publication has a resistor attached to the flat surface of the water-cooled sink, only one side of the resistor that is in contact with the water-cooled sink is forcibly cooled, and the resistance is reduced. If the capacity is small, the calorific value is small and it can withstand practical use, but it is not suitable for a material that has a large resistance capacity and emits high heat. In addition, the conventional water-cooled resistor is installed in the electric control box together with control equipment and precision equipment equipped with various semiconductors, and when the high voltage is applied between the terminals, the water-cooled resistor becomes a water-cooled sink. Corona discharge may occur between the lead wires, which may ignite surrounding combustible materials.The electromagnetic waves generated by the corona discharge may cause a malfunction in the semiconductor device inside the control device or may cause electromagnetic interference in the surrounding area. There was a risk of suffering.

It is held so that each resistor is connected in series via a connector, and each connector connects to the water cooling sink so that it can be energized, and the terminals protruding from the resistors at both ends can be energized to the water cooling sinks at both ends. It is characterized by being connected.

It becomes equal to the child and can prevent the occurrence of corona discharge. Further, since both sides of each resistor are in contact with the water cooling sink, the generated heat can be quickly removed from both sides and a large capacity resistance can be dealt with.

In the frame body 1, the resistors 2 and the water-cooled sinks 3 made of metal and having conductivity are alternately arranged, and both ends thereof are water-cooled sinks 3.
The resistor 2 is formed by stacking a plurality of resistors so as to be terminated with a resistor element 4 such as a thin surface nichrome plate, and an insulating sheet 5 such as a ceramic plate having a high thermal conductivity and a high insulating property. The water-cooled sink 3 has a hollow interior, a water passage 6 through which cooling water circulates, and a water supply port 7 and a drain port 8 on the outside, which are adjacent to each other. The water supply port 7 and the drainage port 8 of the water cooling sink 3 are connected in series by pipes 9, respectively, so that cooling water circulates in each water cooling sink 3.

抗値が得られる。The resistors 2 are connected in series via a connector 10. The connector 10 is made of a copper alloy block body, and one end of the connector 10 projects from the water cooling sink 3. It is fixed to the projecting piece 11 so that it can be energized, and the other end is connected to one end of the resistance element 4. A terminal 12 is provided on each connector 10 in a protruding manner. Therefore, an appropriate resistance value can be obtained by using the terminals 12 at both ends or the terminals 12 in the middle.

Tight bolts 14 are provided, and insulating spacers 15 and 15 are interposed between the water-cooled sinks 3 and 3 at both ends and the substrate 13, respectively.
By tightening the tight bolt 14 with a nut, the water cooling sink 3 and the resistor 2 are held in a state of being sandwiched between the substrates 13 and 13.

生した熱は抵抗体２の両面から速やかに除去される。The water-cooled resistor according to the present invention is connected to each of the water-cooled sinks 3 so that it can be energized. When a voltage is applied to both terminals 12, 12, no current flows through the water-cooled sink 3, but it is the same as the connector 10. The potential is reached, corona discharge does not occur between the water-cooled sink 3 and the connector 10, and since each resistor 2 is sandwiched between two water-cooled sinks 3, the heat generated is generated by the resistor 2. It is quickly removed from both sides.

とはなく、非常に安全性が高いものである。By using the water-cooled resistor according to the present invention,
Even when a high voltage is applied, the potentials of the water cooling sink and the connector interposed between the resistors are the same, so that corona discharge does not occur between the water cooling sink and the connector. Therefore, there is no danger of ignition to the surroundings due to corona discharge, damage to the semiconductor element of the control device due to electromagnetic waves, electromagnetic interference, etc., and the safety is very high.

抗器を小形化、大容量化及び集積化することができる。Since the resistor is sandwiched by the water cooling sink from both sides thereof, the cooling efficiency of the heat generated from the resistor is extremely enhanced, and therefore a large amount of cooling water is not required, and the water cooling resistor is downsized and large. Capacitance and integration are possible.
