Abstract

PURPOSE:To improve cooling effect by dividing the interior of a panel case unit in the vertical direction into a heat generation section-housing part and a heat radiation section-housing part and cooling a heat radiation section in the interior of the heat radiation section-housing part by the outside air sucked from the lower direction and released to the outside. CONSTITUTION:Two sheets of partitioning plates 9 are provided in the vertical direction in a panel case unit 6 which is divided into two heat generation section-housing parts 8A, housing two heat generation sections 7A of two sets of electric equipments 7, and a single heat radiation fin-housing part 8B for opposedly housing heat radiation fins 7B. The heat radiation fin-housing part 8B serves as a chimney-shaped ventilating path arranged, on the inside, with the heat radiation fins 7B to which heat is transmitted from the heat generation sections 7A, and the heat radiation fins 7B are cooled by the outside air sucked through a suction air hole 5A of a base channel 5, lower part suction air hole 6A of the panel case unit 6 and a lower part suction air hole 4A of a side door 4, as a result, the outside air, increased with its temperature, is moved in the upper direction and released to the atmosphere via an upper part discharge hole 6B of the panel case unit 6 and a lower surface discharge hole 1A of a roof 1.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a board box body in which an electrical device placed on a base channel and consisting of a heat generating part and a heat radiating part is housed, and an upper end of this board box body. The present invention relates to an outdoor type control panel having a roof mounted on a wall, and particularly to an outdoor type control panel having a cooling ventilation passage inside the panel case.

(Prior art) Conventionally, when installing an electrical device consisting of a heat generating part and a heat radiating part, such as a variable voltage variable frequency inverter device (VVV "inverter device @)" in a control panel, when this control panel is an indoor type, The cooling effect of electrical equipment was achieved by housing the heat generating part inside the control panel and exposing the heat radiating part (radiating fins) outside the control panel to radiate heat to the outside air.

(Problem to be Solved by the Invention) When this control panel is an outdoor type, exposing the radiating fins outdoors can provide a cooling effect for electrical equipment, but it is exposed to raindrops that enter through the radiating fins. In order to prevent electrical equipment from being corroded and damaged, it was necessary to house the entire electrical equipment within a control panel. Although this makes it possible to avoid damage to electrical equipment due to intrusion of raindrops, there is a problem in that a sufficient cooling effect cannot be obtained.

In view of the above points, it is an object of the present invention to provide an outdoor control panel that effectively solves the problems of the prior art, prevents raindrops from entering, and achieves a sufficient cooling effect.

(Problems to be Solved by the Invention) In order to achieve such an object, the present invention has a panel box body in which an electric device consisting of a heat generating part and a heat radiating part is housed and a roof is placed on the upper end. In the outdoor type 1 control panel, the inside of the panel box body is vertically divided into a heat generating part accommodating part for accommodating the heat generating part and a heat radiating part accommodating part for accommodating the heat radiating part, and The heat dissipating section is provided with a partition wall plate that forms a cooling ventilation path through which the outside air, which has been cooled by the outside air taken in from below and whose temperature has risen, moves upward and is discharged to the outside through the roof. Features and Features: 16° (Function) The present invention provides a partition plate in the vertical direction inside the panel box body, and the partition plate serves as a heat generating part accommodating part that accommodates a heat generating part and a heat radiating part accommodating part that accommodates a heat radiating part. The board box body is divided, and the inside of the heat radiating part housing part is cooled by the outside air taken in from below by the heat radiating part, and the outside air whose temperature has risen moves upward and is released to the outside through the roof. The ventilation path prevents electrical equipment from being directly exposed to raindrops, preventing damage to them.
Its environmental resistance is improved and, moreover, a sufficient cooling effect is achieved.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment of the present invention, and FIG.
A sectional view taken along line A-A in the figure is shown. In FIGS. 1 and 2, an outdoor control panel 100 mainly includes a roof 1, front and rear doors 2, 2A, side plates 3, side doors 4, a base channel 5, and a panel box body 6. Two partition plates 9 are vertically provided in this panel box body 6, and two heat generating part accommodating parts 8A in which two heat generating parts 7A of the electrical equipment 7 of 'l are accommodated; The heat dissipating fin accommodating portion 8B is divided into 18] heat dissipating fin housing portions 8B in which two heat dissipating fins 7B are accommodated facing each other.

In addition, the roof 1 has a lower roof exhaust hole 1A, the side door 4 has a side surface m lower intake hole 4A, the base channel 5 has a base 1 non-nel air intake hole 5A, and the panel box body 6 has a lower panel case body intake hole 6A and Each board box body upper part exhaust hole 6B is provided.

Note that the radiation fin housing portion 8B serves as a chimney-like ventilation passage, and the heat transferred from the heat generating portion 7A to the radiation fins 7B disposed therein is transferred to the air intake hole 5A of the pace V tunnel 5,
! The outside air taken in from the lower air intake hole 6A of the box body 6 and the lower air intake hole 4A of the side surface m4 cools the outside air, and as a result, the outside air with increased humidity is moved upward, and the upper air exhaust hole 6B of the panel body 6 and the roof are cooled. It is released into the atmosphere via the lower surface JIG pores 1A of 1.

In this way, the fin accommodating portion 8B is intentionally formed as a chimney-like ventilation path by the partition plate 9, so the cooling effect of the radiation fins 7B of the electrical equipment 7 is large, and it is separated from the heat generating portion 7A by the partition plate 9. Therefore, the influence of heat radiation is not transmitted to the inside of the panel box body 6. Moreover, since the heat dissipation part 7B is also covered by the roof 1 and allows outside air to flow through it, the electrical equipment 7 is not directly exposed to raindrops, corrosion thereof is prevented, and its environmental resistance performance is improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but may be modified in other embodiments by making appropriate design changes, for example, one heat generating part accommodating section 8A for accommodating one set of electrical equipment 7. It is also possible to implement the present invention with a panel box body consisting of one partition wall plate 9 forming the radiation fin housing portion 8B.

(Effects of the Invention) As described above, according to the present invention, the inside of the panel box body is vertically connected to the heat generating part accommodating part in which the heat generating part of the electrical equipment is housed and the heat radiating part accommodating part in which the heat radiating part is housed. A partition plate is provided that is divided into two directions, and the heat dissipation section is cooled by the outside air taken in from below, and the outside air whose temperature has increased moves upward and is released to the outside through the roof. The problems of the conventional technology can be effectively solved by using a radiator fin, which can achieve sufficient cooling effect of the radiation fins, prevent raindrops from entering, and improve the environmental resistance performance of electrical equipment. play.
