Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat pipe type case cooler installed inside a case such as a control panel or a switchboard.

[0002]

[Prior Art]

 A conventional heat pipe type case cooler has a structure as shown in FIG. Reference numeral 60 in the figure denotes a housing such as a control panel or a switchboard. An opening 61 for ventilating the outside air is formed in the housing 60. A cooler main body 62 is installed in a region inside the housing 60 and including the opening 61. The cooler main body 62 is composed of a fan 63 arranged corresponding to the position of the opening 61, and a finned heat pipe 65 arranged in the center of the cooler main body 62 by jigs 64 and 64 ′. ing. Further, a filter 66 for removing oil mist contained in the outside air is attached to the outer wall of the fan 63. The filter 66 may be attached to the housing 60 so as to include the opening 61 of the housing 60 as shown in FIG. 7.

[0003]

[Problems to be solved by the device]

 However, in the heat pipe type cooler having the above-described configuration, the filter 66 is adjacent to the cooler main body 62, so that the oil captured by the filter is transmitted through various members and cooled. Enter the inside of the container body 62. Further, this oil component penetrates the inside of the casing 60 through the finned heat pipe 65 and the jig 64 in the cooler body 62.

This oil may reduce the cooling capacity inside the cooler main body 62, or may adversely affect the control equipment inside the housing 60.

The present invention has been made in view of the above points, and a heat pipe type casing cooling system capable of sufficiently cooling the inside of the casing without allowing oil contained in outside air to enter the inside of the casing. The purpose is to provide a container.

[0006]

[Means for Solving the Problems]

 The present invention provides a cooler main body, which is provided inside an enclosure having an opening for ventilating outside air so as to communicate with the opening, and accommodates a heat pipe and a fan, and is arranged outside the enclosure. A filter that removes oil contained in the outside air that flows in through the section and holds the filter at a predetermined distance from the housing to prevent the oil captured by the filter from entering the housing. And a filter holder attached to an opening for ventilating the outside air of the casing having a means for controlling the heat pipe type casing cooler.

Here, as a means for preventing the oil content of the filter holder from entering the housing, a trough-shaped oil reservoir is provided in the holder that supports the lower end of the filter, and the lower end of the filter is Examples of the method include providing an opening in a holder that supports the filter, and inclining the holder that supports the lower end of the filter. The cut surface of the gutter-shaped oil sump may have any shape such as a substantially U-shape, a substantially V-shape, and a substantially semicircular shape as long as the oil can be accumulated. Needless to say, the above means may be used in combination.

[0008]

[Action]

 The heat pipe type cooler of the present invention is provided with a filter holder having means for holding the filter at a predetermined distance from the casing and preventing the oil content captured by the filter from entering the casing. It has.

Therefore, the oil content contained in the outside air is captured by the filter and is either stored in the filter by the above means or discharged to the outside. Therefore, it is possible to completely prevent the oil content captured by the filter from entering the inside of the housing. As a result, it is possible to prevent the control devices in the housing from being adversely affected and the cooling capacity from being lowered.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a schematic explanatory view showing an embodiment of a heat pipe type case cooler of the present invention. Reference numeral 10 in the figure denotes a housing such as a control panel or a switchboard. The housing 10 is formed with an opening 11 for ventilating outside air. A cooler body 12 is installed inside the housing 10 in a region including the opening 11. The cooler main body 12 is composed of a fan 13 arranged corresponding to the position of the opening 11, and a heat pipe 15 installed by a jig 14 at the center of the cooler main body 12.

Filter holders 16 and 17 are attached to the opening 11 of the housing 10. The filter holder 16 has a substantially L-shaped cross section, and the flange portion 18 is attached so as to face downward. Further, the filter holder 17 has a trough portion 19 and is attached to the trough portion 19 so that the oil content 20 can be stored. The filter 21 for removing oil components such as oil mist contained in the outside air is attached so that its upper end is held by the filter holder 16 and its lower end is held by the filter holder 17.

According to the heat pipe type case cooler having such a configuration, when the outside air enters the inside of the case from the direction of the arrow, the filter 21 captures oil components such as oil mist contained in the outside air. The outside air that has passed through the filter 21 is introduced into the cooler main body 12 by the fan 13, and the high temperature air inside the housing 10 is cooled by the heat pipe 15.

On the other hand, the oil content captured by the filter 21 is transmitted through the filter 21 and stored in the trough portion 19 of the filter holder 17. Therefore, it is possible to prevent the oil contained in the outside air and the oil stored in the trough 19 of the filter holder 17 from entering the housing. Further, the filter 21 can prevent dust and the like from entering the housing.

In the present invention, the means for preventing the oil component flowing out of the filter from entering the housing is not limited to this embodiment, and the filter holder 17 for holding the lower end of the filter 21 is As shown in FIG. 2, it may have a trough portion 30 having a substantially V-shaped cross section. Further, as shown in FIGS. 3 and 4, the filter holder 17 holding the lower end of the filter 21 may be provided with a hole 40 to discharge the oil to the outside. Further, as shown in FIG. 5, the filter holder 50 for holding the lower end portion of the filter 21 is extended from the position of the filter 21 and is provided so as to be inclined, so that the oil component transmitted from the filter 21 is exposed to the outside. It may be configured to be discharged.

[0016]

[Effect of the device]

 As described above, the heat pipe type case cooler of the present invention can sufficiently cool the inside of the case without allowing oil contained in the outside air to enter the inside of the case.
