題があった。However, in these configurations, the above-mentioned (a)
In this configuration, the air does not hit only a small part of the circumference of the X-ray tube device, so the cooling efficiency is low, and in order to increase the cooling area, multiple blowers are sometimes used for cooling.
The rotating noise of the blower increases, making it difficult to hear the patient's voice through the interphonon, so the blower is made smaller to reduce the air volume and reduce the rotating noise. As a result, the cooling characteristics inevitably deteriorated due to the small air volume. Although the configuration described above currently has the best cooling efficiency, the overall configuration of the X-ray tube device increases in size and weight due to the attachment of connecting pipes, hoses, coolers, etc. Moreover, it is complicated to handle, and it may not be possible to install it depending on the X-ray tube device.
Additionally, there were other problems such as the product being expensive. However, in the above-mentioned configuration (c), the total length of the X-ray tube device is increased by about 20 mm because the blower is installed in the axial direction of the X-ray tube container, and for this reason, the installation on the X-ray device must be rotated. Sometimes the X-ray tube device and the floor surface come into contact, which limits the conditions of use. Furthermore, MACHLETECH
According to NICAL DATA, silicone grease is applied between the X-ray tube container and the cooling fins to improve thermal conductivity, but it generally has a heat transfer rate of one to three orders of magnitude compared to aluminum or copper. There were problems such as a decline in the rate.

るが、風の当る表面積が小さいために冷却特性が低い。FIG. 1 shows an example of an X-ray tube device with a conventional structure equipped with this type of blower, with (&) in the figure being a side view and (b) being a plan view. In the figure, a blower 4 is fixed to the side surface of the X-ray radiation opening 2 of the X-ray tube container 1 with screws 3, and the air sent out from the blower 4 is blown onto the X-ray tube container 1 to cool it. . In addition, a structure has been proposed in which a special adapter is attached to the left end 1a + right end 1b of the X-ray tube container 1, and the blower 4 is fixedly installed, but since the surface area exposed to the wind is small, cooling Characteristics are low.

せて回転させた場合に床面と接触することもあった。Further, as shown in FIG. 2, the left end portion 1a of the X-ray tube container 1,
Cooling fins 6 are fixed to the surfaces of the right end portion 1b and the center portion 1C using metal bands 5, and furthermore, a blower 4 is attached and fixed to, for example, the left end portion 11L of the X-ray tube container 1 to blow air in the tube axis direction. An X-ray tube device that cools by blowing air has been proposed. According to this configuration, in order to blow air onto the outer circumferential surfaces of the left end [a], right end 1b, and center 1C of the X-ray tube container 1, Since the blower 4 is larger than the outer diameter of the X-ray tube container 1 and needs to be installed at a certain distance from the left end 1a, the total length is approximately 20 inches or more compared to the structure shown in FIG. It was so long that it sometimes came into contact with the floor when rotated in combination with an X-ray device.
