JPH09326618A - Housing structure for microwave or milliwave radio equipment - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a housing structure for radio equipment low in cost without using any power source and capable of preventing ice or snow from being stuck onto the surface of a radome for the antenna. SOLUTION: Microwave or milliwave radio equipment 1 is fitted to the opening surface of a Cassegrain-type antenna 6. The antenna 6 is provided with a radome 7. Between the radio equipment 1 and the antenna 6, a ventilation route 8 two-way communicating with them is formed, one end of the ventilation route 8 is communicated into the radio equipment 1 and the other end is communicated to the radome 7. Then, an air blower fan 9 is installed at the opening part of the ventilation route 8 inside the radio equipment 1. Air of which the temperature is increased because of heat generation inside the radio equipment 1 is circulated between the antenna 6 and the radome 7 from the radio equipment 1 by operating the air blower fan 9. With this temperature circulation, ice or snow can be easily prevented from being stuck onto the radome 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casing structure of a microwave or millimeter wave radio having a structure directly attached to an aperture antenna having a radome.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional radio device. The microwave or millimeter wave radio 1 is directly attached to the opening surface of the parabolic antenna 2 or the like. Radome 3 for antenna 2
However, since ice and snow adheres to this, a heater 4 for preventing the adhesion of ice and snow is attached. Reference numeral 5 is a heater lead wire.

Conventionally, as shown in the drawing, in a microwave or millimeter wave radio installed outdoors in a snowfall area in winter, the radome 3 is covered with a heater 4 to prevent ice and snow from adhering to the surface of the radome 3.

[0004]

However, an AC power source is required to operate the heater 4, and it cannot be used outdoors without the AC power source. In addition, there is a drawback that power consumption increases even if there is an AC power source.

An object of the present invention is to solve the problem that an AC power source is required in the case of using this heater and the power consumption increases, and at a low cost, it is possible to prevent ice and snow from adhering to the radome surface of the antenna. To provide.

[0006]

The above object can be achieved by providing means for circulating air whose temperature has risen due to heat generated in a radio, in a radome.

By using the above means, it is possible to keep the radome warm by using the exhaust heat of the wireless device and prevent the adhesion of ice and snow.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Reference numeral 1 denotes a microwave or millimeter wave radio device similar to the conventional one, which is attached to the opening surface of a Cassegrain antenna 6. A radome 7 is provided on the antenna 6. An air passage 8 communicating with the wireless device 1 and the antenna 6 is formed by reciprocating circulation. One end of the air passage 8 communicates with the inside of the wireless device 1 and the other end communicates with the radome 7. A blower fan 9 is provided at the opening of the ventilation passage 8 in the wireless device 1.

By forming the ventilation passage 8 in this manner, the air whose temperature has risen due to the heat generation inside the wireless device 1 due to the operation of the blower fan 9 is transmitted from the wireless device 1 to the antenna 6 and the radome 7.
It begins to cycle between. This warm air circulation can easily prevent ice and snow from adhering to the radome 7. In addition, a heat exhaust effect is obtained inside the wireless device by the circulation operation of air, and a stable operation effect of the internal device is obtained.

It should be noted that the fan 9 may be blown or sucked by making the inside of the radio 1 a closed structure.

[0012]

By implementing the present invention as described above, a microwave or millimeter wave radio can be installed and operated outdoors. It is possible to prevent ice and snow from adhering to the aperture antenna radome surface without increasing the cost. No electric power is required to prevent the adhesion of ice and snow, and it is possible to obtain an effect that the outdoor installation is not restricted by the presence or absence of an AC power source.
