Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is housed in a streamlined containment vessel (hereinafter referred to as POD) which is a housing box for electronic devices loaded under the wing of an aircraft flying at high speed. It also relates to a POD cooling device for cooling electronic devices.

[Conventional technology]

Conventional devices of this type have been cooled by air (hereinafter referred to as ram air) taken in through an opening in a wall on the front surface (direction of travel) of the POD, that is, air that has been adiabatically compressed and becomes hot. FIG. 2 shows this conventional POD cooling device. (1) is a POD body loaded under the wing of an aircraft, etc., and has air introduction openings (1
a) and a discharge opening (1b) are provided. (2) is an electronic device (unit) provided inside the POD main body (1).

Next, the operation will be described in detail. As the aircraft speeds up, the air pressure on the front of the POD, that is, the difference between the air pressures on the advancing direction side and the opposite side (referred to as P1 and P2 respectively) increases, and the cooling air W1 flows into the POD from the front of the POD. , The inflowing air cools the heat generated by the unit (2) in the POD, and becomes the air W2 whose temperature rises by the amount of the cooling, resulting in the POD.
Sent out.

[Problems to be solved by the invention]

Since the conventional POD cooling device is configured as described above, when the speed of the aircraft is high, the air (W1) in front of the POD is adiabatically compressed, and the electronic equipment inside the POD is not sufficiently cooled due to the warm air. There was a drawback to say.

The present invention has been made to solve the above-mentioned problems, and an air intake port on the front side is attached to the opposite side so as not to be affected by adiabatic compression, and the internal electronic device can be sufficiently cooled. It is intended to provide a POD cooling device that can be used.

[Means for solving problems]

In order to prevent adiabatic compression, the POD cooling device according to the present invention is provided with an outside air introduction opening on the POD wall surface (rear wall) opposite to the traveling direction and takes in outside air from this opening.

[Work]

In the present invention, the outside air introduction opening is provided on the rear wall of the POD so that it is not affected by the adiabatic compression action and the electronic device is cooled efficiently.

Example of Invention

FIG. 1 is an overall view of an embodiment of the POD cooling device according to the present invention. In this embodiment, as is apparent from FIG. 1, a POD main body (1) attached to an aircraft flying at high speed is provided with an introduction pipe (1c) for taking in air from the rear,
The air W1 that is not affected by adiabatic compression is taken into the POD. At this time, a fan (3) for surely taking in and controlling the taking-in amount is provided as shown in Fig. 1. The taken-in cooling air is POD. The unit (2) which flows through the inside and is generating heat is cooled. Warm air due to cooling
W2 is sent out of the POD through the discharge pipe (1a). In this way, the inside of the POD is cooled using the outside air.

That is, when the fan (3) rotates, the inside of the air introduction pipe (1c) becomes a negative pressure than the outside air, and the outside air (W
1) flows into the POD. The inflowing air travels around the unit (2) in the POD and absorbs the amount of heat generated by the unit (2). The warmed air (W2) is discharged into the atmosphere through the discharge pipe (1a).

〔The invention's effect〕

As described above, according to the present invention, since the outside air for cooling is taken in from the rear part of the POD that is not affected by the adiabatic compression, the electronic device inside the POD can be sufficiently cooled by the outside air.
