Is an external fan that blows air from the end of the heat radiating portion 45b of the heat pipe 45 and discharges it from the external air outlet 37, and is located near the end of the heat radiating portion 45b, that is, on the right side of the end of the heat radiating portion 45b in the drawing. It is attached to 30. 49 is a heat radiating portion 45b of the heat pipe 45.
Is a jetting device that is provided on the side opposite to the external air outlet 37 and that removes dust and the like adhering to the heat radiating portion 45b of the heat pipe 45 by jetting compressed air such as factory air from the jet outlet. .. This ejection device 49 is
A pipe 50 for supplying compressed air, an air ejection pipe body 51 connected to the pipe 50, and a plurality of air ejection pipe bodies 51 are formed. For example, the hole diameter is larger on the air outlet side. It is composed of a trumpet-shaped ejection port (not shown) and a boss 52 that connects the pipe 50 and the ejection pipe body 51.

Next, the operation will be described. The internal air A is heated by the heat generated by electronic parts, electric devices, etc. (not shown) housed inside the panel, and the temperature rises. The internal air A is guided by the internal fan 47 to the end extending direction side of the heat receiving portion 45a of the heat pipe 45 inside the casing 30. The internal air A changes direction from the end extending direction side of the heat receiving portion 45a of the heat pipe 45, passes through the entire heat receiving portion 45a of the heat pipe 45, and returns to the inside of the board for circulation. When the heat receiving portion 45a of the heat pipe 45 is heated by the internal air A, the working liquid inside the heat pipe 45 evaporates while taking heat in the form of latent heat of vaporization, and the vapor passes through the heat pipe 45 to form the heat pipe. It moves to the heat radiation part 45b of 45. On the other hand, the external air B is guided by the external fan 48 to the end extending direction side of the heat radiating portion 45b of the heat pipe 45. The external air B changes its direction from the end extending direction side of the heat dissipation portion 45b of the heat pipe 45, passes through the entire heat dissipation portion 45b of the heat pipe 45, and is discharged to the outside. The hydraulic fluid inside the heat pipe 45 cooled by the external air B is condensed and liquefied to radiate heat, and then returns to the heat receiving portion 45a side of the original heat pipe 45. By naturally repeating such an operation, the heat of the internal air A is transferred to the external air B to be released and the inside of the board is cooled. By the way, since the external fan 48 is not provided with a filter, dust or the like mixed in the external air B tends to adhere to the heat radiating portion 45b of the heat pipe 45 due to the driving of the external fan 48. Compressed air such as factory air is ejected from the trumpet-shaped ejection port formed in 51 to remove dust and the like adhering to the heat dissipation portion 45b of the heat pipe 45. As described above, since the filter is not used, maintenance such as cleaning the filter with a chemical agent or the like is unnecessary, and a great deal of time and labor is not required. Therefore, stable operation can be realized for a long time without stopping the operation of the device or the operation of the control panel or the like. In addition, the heat receiving portion 4 of the heat pipe 45
Since the internal fan 47 and the external fan 48 are arranged on the lower side and the upper side of the heat radiating portion 45b and the heat radiating portion 45b, respectively, the overall size and thickness of the device can be reduced. Further, by arranging the heat pipes 45 in an inclined manner, it is possible to obtain a heat exchange device having further improved heat exchange characteristics as compared with the above-mentioned respective embodiments.

Example 8. In addition, in the said Example 7, although the case where the ejection device 49 was provided in the heat radiation part 45b of the heat pipe 45 in the anti-outside air outlet 37 side was described, the ejection device 49 was equipped with the external air of the heat radiation part 45b of the heat pipe 45. It may be provided on the side of the outlet 37 or on the other heat dissipation portion 45b, and has the same effect as that of the seventh embodiment.

The heat pipe has a thin structure in which a working fluid such as water or ammonia is enclosed, and a plurality of heat pipes are provided in a row, for example. Reference numeral 46 is a fin attached to the heat pipe 45, and 47 is provided in the internal air introduction port 34. For example, the internal air A is blown from the lower part of the heat receiving portion 45a of the heat pipe 45 and is returned to the inside of the panel from the internal air discharge port 35. It is an internal fan and is attached to the casing 30 so as to be located below the heat receiving portion 45a. An external fan 48 is provided in the external air inlet 36 and blows the external air B from, for example, the upper portion of the heat radiating portion 45b of the heat pipe 45 and discharges it from the external air outlet 37.
It is attached to the casing 30 so as to be located above the 5b. 49 is provided on the heat radiation part 45b of the heat pipe 45, for example, on the side opposite to the outside air outlet 37,

Next, the operation will be described. The heat exchange operation of the heat pipe 45 is the same as that of the fifth embodiment described above, and thus the description thereof is omitted. By the way, since the external fan 48 is not provided with a filter, dust or the like mixed in the external air B tends to adhere to the heat radiating portion 45b of the heat pipe 45 when the external fan 48 is driven. When it is desired to remove dust or the like, the switch mechanism 54 is turned on to open the control valve 53, and compressed air such as factory air is ejected from the trumpet-shaped ejection port formed in the ejection pipe body 51 of the ejection device 49. Then, dust and the like attached to the heat dissipation portion 45b of the heat pipe 45 is removed. When the removal of dust is completed, the switch mechanism 5
4 is turned off to close the control valve 53. As described above, since the filter is not used, maintenance such as cleaning the filter with a chemical agent is unnecessary, and a great deal of time and labor is not required. Therefore, it is not necessary to stop the operation of the device or the operation of the control panel or the like, and stable operation can be realized for a long time. Further, when the dust or the like is desired to be removed, the dust and the like can be removed very simply by opening and closing the control valve 53 by the ON / OFF operation of the switch mechanism 54.
