[Structure] The heated cooling medium 3 guided from the lower part of the heat dissipation device 6 is used as a flow path inside the partition plate 8 and is guided to the uppermost part of the heat dissipation device 6, and the corrugated plate 9 releases heat to the outside air. Then, the cooled cooling medium 3 is collected in the lower common channel 10 and guided to the container 7 through the outlet pipe 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat dissipation device for electric equipment.

[0002]

[Prior art]

 FIG. 4 is a diagram showing an example of a conventional heat dissipation device for an electric device. In the figure, the heat generated from the iron core 1 and the winding 2 raises the temperature of the cooling medium 3. The heated cooling medium 3 is guided to the heat dissipation device 6 through the inlet pipe 4. In the heat dissipation device 6, the cooling medium 3 dissipates heat to the outside air to lower the temperature, and is guided to the container 7 through the outlet pipe 5.

[Problems to be solved by the device]

 However, since the conventional heat dissipation device for electric equipment is configured as described above, the inlet pipe 4 for connecting the container 7 and the heat dissipation device 6 is required. Further, although the inlet pipe 4 has a small outer surface area and a heat dissipation effect cannot be expected, it occupies a large installation area in the upper part of the container 7 and reduces the floor area on which the heat dissipation device 6 is installed. Therefore, in order to obtain the heat dissipation device 6 having a heat dissipation area necessary for cooling the cooling medium 3 to a predetermined value, it is necessary to increase the height dimension and the width dimension, and increase the size of the entire electric device. There were drawbacks such as doing. Therefore, the present invention has been made in order to solve the above problems, and it is possible to omit the inlet pipe connecting the container and the heat dissipation device and to obtain a floor area sufficient for installing the heat dissipation device on the upper part of the container. The purpose is to provide a heat dissipation device for electric equipment.

[0004]

[Means for Solving the Problems]

 In the present invention, the corrugated plates are arranged on both sides, the inner side is separated by the partition plate and used as a flow path, so that the inlet and the outlet to the heat dissipation device are arranged in the lower part.

[0005]

In the heat dissipation device for electric equipment of the present invention configured as described above, even if the cooling medium inlet is arranged in the lower portion, the cooling medium reaches the top of the heat dissipation device without reducing the driving force of natural convection. Therefore, the inlet and the outlet can be arranged in the lower portion without deteriorating the heat radiation effect. Further, by arranging the inlet and the outlet at the lower part, the inlet pipe 4 for connecting the conventionally required container 7 and the heat dissipation device 6 is not required. Therefore, the floor above the container 7 where the inlet pipe 4 is installed is installed. The area portion can be effectively used as the floor area of the heat dissipation device 6.

【Example】

 1, FIG. 2 and FIG. 3 show an example of a heat dissipation device for electric equipment of the present invention, FIG. 1 is a side view, FIG. 2 is a front view, and FIG. 3 is a three-dimensional view. In FIG. 1, 1 is an iron core, 2 is a winding wire, 3 is a cooling medium, 4 is an inlet pipe, 5 is an outlet pipe, 6 is a heat dissipation device, 7 is a container, 8 is a partition plate, 9 is a corrugated plate, and 10 is It is a common channel. The cooling action in one example of the present invention will be described. In FIG. 1, the heat generated from the iron core 1 and the winding 2 raises the temperature of the cooling medium 3. The heated cooling medium 3 is guided inside the partition plate 8 of the heat dissipation device 6 through the inlet pipe 4. Since the outside of the partition plate 8 has few places in contact with the outside air, the cooling medium 3 is guided to the corrugated plate 9 from the uppermost part of the heat dissipation device 6 while the temperature is raised. The heated cooling medium 3 guided to the corrugated plate 9 is guided to the lower portion while releasing heat to the outside air, and the cooled cooling medium 3 gathers in the lower common flow channel 10 and passes through the outlet pipe 5 to the container. Draw a circulation cycle that returns to 7.

[Effect of device]

 According to the present invention, as described above, since the function corresponding to the conventional inlet pipe 4 is configured by the partition plate 8 inside the heat dissipation device 6, when the floor area and height of the heat dissipation device are the same, The heat dissipation area of the heat dissipation device can be greatly increased. In other words, when the temperature rise of electrical equipment is the same, the heat dissipation area of the heat dissipation device can be the same. Therefore, when the height is the same as the conventional product, the floor area can be made smaller and the heat dissipation device becomes compact. be able to.
