Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention has a heating medium that repeats evaporation and condensation sealed inside, one end of which is a heating section (evaporation section), and the other end of which is a heat dissipation section (
The present invention relates to a cooling device that cools the inside of a closed box such as a control panel using a so-called "heat vibrator" (condensing section).

[Prior Art] Figure 1 is a sectional view showing a conventional cooling device of this type.
is a sealed box, such as a power distribution board, which houses electronic components or electrical equipment (not shown) inside. This sealed box (1
), the mounting plate (4) that closes the opening (1a) drilled in the ceiling has a heating medium such as ammonia or methyl alcohol sealed inside, and has heat absorbing fins (IQa) in the lower half. A pair of heat pipes (2) forming a heating part (2a) and having a heat dissipating part (2b) having heat dissipating fins (10b) on the upper part are inserted and supported almost to the middle part of the heat pipes. (2) is maintained by a protective case (3). (5) is the heating section (2a) of the beet pine (2) in the sealed box (]).
), and (6) is an external cylinder and motor disposed facing the heat dissipation part (2b)' of the heat pipe (2) outside the sealed box 0). fan,(
7) is blown onto the heating part (2a) of the heat pipe (2) by the internal electric fan (5, 1), and due to the cooling effect accompanying the evaporation of the hot W body in this heating part (2a). The internal air to be cooled (8) is the heat dissipation part C2b of the heat pipe (2) by the external electric fan (6).
It is the external part 9 that condenses and liquefies the thermal barrier that has been evaporated and evaporated in the heating part (2a).

Conventional cooling devices of this type have been tested as described above, so the internal space (7) inside the sealed box (1) is heated by the heat generated by the electronic components or side equipment contained therein, and is heated to the brim. i rises. Then, this internal air whose temperature has increased (7
) is powered by the heat pipe (
2) is sprayed onto the heating section (2a);
When the heating medium inside the vibrator (2) is heated, this # medium evaporates while taking away the heat of the attached internal air (7) in the form of latent heat of vaporization, and the heat dissipation part (2b) of the heat pipe (2)
rise to The evaporated heat medium is cooled by the external air (8) blown onto the heat dissipation section (2b) by the external electric fan (6), and is condensed and liquefied. ), but
The heating section (2a) is blown into the heating section (2a) by the internal wave fan (5) and heated again by the internal air (7), and by completing the above-mentioned operation, the airtight box (0) is heated.
) is cooled to a predetermined temperature.

However, in the above-mentioned conventional cooling device, the heating part (2a) and the heat radiation part (2b) of the dopane stem 2) are placed in the vertical direction of the internal electric fan (5) and the external dynamic fan (6). Not only does the thickness of the cooling system itself become large because the parts are cut in a stacked manner, but also the heating part (2a) of the heat pipe (2) is thicker than the inside of the sealed box (1). Since the heat pipe (2) protrudes for a long time and has a temperature of ℃2, it is possible to install electronic components or electrical equipment near this protrusion. ) also protrudes to the outside of the closed box (1) for a relatively long time, which also has the drawback of restricting the installation of the closed box, that is, the control panel. moreover,
An internal electric fan (
5) and an external dynamic fan (6), there is also the drawback that the air velocity distribution around the heat pipe (2) is uneven, resulting in poor cooling efficiency. .

1 Summary of the Invention] was made with this point in mind. A heat pipe is disposed on one side of the sealed box in parallel with this, and furthermore, the heating part of this heat pipe and The heat dissipation section is configured such that the inner air flow passage and the outer wall air flow passage are arranged such that the inner air and the outer wall air flow passage 91 flow in through a pair of inlets and exit through a single outlet in the middle part. It is partitioned by a plurality of partition plates, and an internal electric fan and an external electric fan are respectively arranged in the internal air flow path and the external air flow 11, thereby reducing the thickness of the sealed box, that is, the control panel, and improving the cooling effect of the heat pipe. The object of the present invention is to provide a cooling device that can improve the performance of the cooling device.
