Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high-frequency heating device using a heat pipe as a cooling means for a high-frequency heating heat source.

Conventional configurations and their problems There are some that use a heat pipe as a cooling means for a high-frequency heating heat source. This conventional example involves wrapping one end of a heat pipe around the anode cylinder of a magnetron, which is a high-frequency heating heat source.
The other end is connected to a radiator fin, so that the heat lost by the anode cylinder of the magnetron is transferred to the two-vehicle radiator fin.

By the way, as is well known, a heat pipe is filled with an appropriate amount of a working fluid that easily evaporates, such as water or fluorocarbon, and this working fluid d: the heating part of the heat pipe (the evaporating part of the working fluid) and the heat radiation part ( (condensing part of the working fluid). The smoother the fluidity of this working fluid, the better the heat conduction characteristics of the heat pipe. Therefore, the relative positions of the evaporating section and the condensing section of the heat pipe and the inclination angle of the communication path between the two directly affect the heat conduction characteristics of the heat pipe.

However, the usage condition of the user (the state in which the device is placed)
In the worst case, the inclination angle of the heat pipe that connects the evaporating section and the condensing section of the heat pipe becomes below the horizontal level, which worsens the fluidity of the working fluid and deteriorates the heat transfer characteristics of the heat pipe. In the worst case, there is a danger that the high-frequency heating heat source may be destroyed.

Objective of the Invention 3 - An object of the present invention is to maintain good thermal conductivity characteristics of a heat pipe used as a cooling means for a high-frequency heating heat source, and to efficiently cool the high-frequency heating heat source. Structure To achieve this object, the present invention includes a display means for displaying the inclination angle in the longitudinal direction of the heat pipe when the device is mounted;
The height adjustment means of the apparatus body is also installed, and the height of the apparatus body is adjusted based on the displayed content of the inclination angle, so that the inclination angle in the longitudinal direction of the heat pipe is adjusted appropriately. In addition to maintaining good thermal conductivity characteristics of the heat pipe, it also has the effect of protecting the high-frequency heating heat source from thermal destruction.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway external view of a high-frequency heating device showing an embodiment of the present invention.

In FIG. 1, the high frequency heating heat source 1 is
9-123190 (2) Consists of a high frequency generator in which the element is an active element. High frequency power generated by this high frequency heating heat source 1 is transmitted via a coaxial transmission line 2 into a heating chamber 3 that accommodates an object to be heated (not shown). In order to efficiently dissipate the power loss of the semiconductor element, which is a component of the high-frequency heating heat source 1 of Kadako, the heating heat source cooling section has a heat pipe 5 connected to the high-frequency heating heat source at one end and having a radiation fin 4 at the other end. It is configured using

Furthermore, a display section 8 for displaying the tilt angle in the longitudinal direction 7 of the heat pipe is provided on the access door 6, which is a component of the heating chamber 3, and a main body support for adjusting the height of the apparatus main body is provided at the bottom of the main body. 9 are arranged.

FIG. 2 is an enlarged cross-sectional view of the display section of FIG. 1 that displays the inclination angle in the longitudinal direction of the heat pipe.

As a means to display the inclination angle, there is a partial air layer 10 inside.
On page 5 of the display, a bar-shaped level meter 12 filled with a liquid 11 having be.

That is, if the air layer 1o is within the proper position range, this indicates that the heat pipe has good heat conduction characteristics.

FIG. 3 is a diagram showing the operation of the main parts of a high-frequency heating device showing an embodiment of the present invention.

The solid line shows an example before adjustment of the main body supports 9a, 9b for main body height adjustment, and the broken line shows an example after adjustment.

Before adjustment, if the inclination angle display 8 corresponding to the inclination angle of the heat pipe longitudinal direction 7 deviates from the proper position as shown in the figure and the air layer of the rod-shaped level meter is at the position shown by 13, then the main body support By adjusting the height of the main body as shown in the figure using the tool 9a, the air layer of the bar-shaped level meter is moved and adjusted to within the appropriate position range shown in Figure 2 indicated by 14, and the horizontal level of the heat pipe 5 is adjusted. Inclination angle θ based on
The broken line shows the heat pipe that has been optimized to have good heat conduction characteristics.

The main body support part is configured to adjust the height of the main body by rotating it, and reference numeral 6 No. 2 15 in the figure is a height adjustment screw part of the main body support part 9a. In one embodiment of the present invention, the display section 8 is disposed at the entrance/exit door, but it is not limited thereto, and it may be disposed anywhere as long as it can display the inclination angle in the longitudinal direction of the heat pipe, which is the gist of the present invention. Further, the display means is not limited to the one embodiment of the present invention, and for example, a display means applying the principle of a pendulum, a curved level meter, etc. may be used.

As described above, the present invention provides a high-frequency heating apparatus equipped with a heating heat source cooling unit using a heat pipe as a cooling means for the high-frequency heating heat source, and a display unit that displays the inclination angle of the heat pipe with respect to the horizontal level in the longitudinal direction.
