DESCRIPTION JPS63144697
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
transducer, and more particularly, to a transducer designed to save space for associated
transmission circuits and to omit cooling equipment and to form a free beam fork. 2. Description
of the Related Art Conventionally, a transducer used as a sensor of a sonar or the like and
operated in water has a structure in which a vibrator and an extremely matching transformer are
housed inside a water resistant metal watertight case. [Problems to be Solved by the Invention]
The above-mentioned conventional transducer is normally limited to the matching transformer
for matching the transducer with the transmitting circuit only in the case of being accommodated
together with the transducer, and therefore the transmitting circuit And other electronic circuits
require a separate space in which to place them, and especially those with heat generation such
as transmission circuits that require special cooling equipment such as water cooling and air
cooling. There is. Also, in the conventional transducer, a plurality of these are often used in
combination in an arrangement structure based on transmission / reception directivity
characteristics to be formed. In this case, the number of transmission circuits for driving each
transducer is not the same as the number of transducers, and one transmission circuit serves as a
driving source of a plurality of transducers. Therefore, there is a problem that so-called beam
homing to obtain arbitrary transmission directivity by freely combining and using the transducer
can not be freely performed. The object of the present invention is to eliminate the abovementioned drawbacks, and in the transducer operated in water, the transmission circuit is housed
in the same watertight case and the heat dissipation is taken into account, regardless of the
matching transformer and the center of the input / output circuit of the vibrator. With the above
structure and K, it is an object of the present invention to fundamentally eliminate the space for
installation of the transmission circuit in the ship and the need for cooling equipment, and to
provide a transducer capable of freely performing beam homing. [Means for Solving the

Problems] The transducer according to the present invention is a transducer housed in a
watertight case and operated in water, wherein the transducer and matching transformer as well
as the input and output to and from the transducer are contained in the watertight case. Even in
the center of the circuit, the transmission circuit is accommodated, and the heat generated by the
heat generating component included in the transmission circuit is dissipated into water through
the watertight case. The present invention will now be described in detail with reference to the
drawings. FIG. 1 is a longitudinal sectional view of an embodiment of a transducer according to
the present invention. Prior to describing the embodiment with reference to FIG. 1, the structure
of a conventional transducer will be described. FIG. 2 is a longitudinal sectional view of a
conventional transducer. The transducer shown in FIG. 2 exemplifies the case where a so-called
Langevin type vibrator of a cylindrical shape is used, and this transducer is sent by arranging a
plurality of such transducers in a predetermined shape.
The present invention is directed to a modular-type unit transmitter / receiver which is
connected to a receiving circuit by a predetermined connection method to form a desired
transmission / reception beam. The transducer shown in FIG. 2 has a watertight case of a water
pressure resistant structure utilizing an aluminum alloy. 1. Rubber cover which covers the
outside of the watertight case 1. Vibrator 3. Alignment transformer 4. ????? A watertight
ground 6 and a cable 7 # are provided. The vibrator 3 is provided with a multilayer cylindrical
vibrator main body 31 utilizing a vibrating material such as ceramic, a front mass 32 for holding
and clamping this with a metal bolt or the like, and a rear mass 33 etc. A sound wave is emitted
from the free end of the front mass through the rubber cover 2. At this time, it is the cork 5 that
prevents unwanted vibration from reaching the watertight case 1. For the rubber cover 2, the
watertight case 1 is usually used to reduce the weight and use an aluminum alloy in many cases,
and it is used for the purpose of preventing corrosion that occurs when it is directly immersed in
water, particularly in seawater. . The matching transformer 4 is also housed inside the watertight
case 1 if it is necessary to provide a matching transformer for impedance matching between the
vibrator 3 and a transmission circuit or the like connected via the cable 7. The watertight ground
6 is a fitting for holding the cable 7 in a watertight state and guiding the cable 7 into the
watertight case 1. By the way, in the transducer of such conventional structure, only the vibrator
and the maximum matching transformer are housed inside, which causes the problems described
above. Therefore, the circuit connected to the transducer, especially the transmitting circuit with
a large amount of heat generation, can be housed inside the watertight case 1, and the heat
generation can be dissipated to seawater etc. as the operating environment of the transducer. For
example, the space for the transmission circuit and the cooling equipment are not required, and
besides, the operation of the transducers can be individually controlled, and beamforming can be
performed freely. However, as described above, the conventional transducer covers the outside of
the watertight case with a rubber cover, and heat dissipation can not be performed as it is. What
solves this problem is the transducer shown in FIG. The transducer shown in FIG. ???????
Vibrator 3. Alignment transformer 4. In addition to the cork 5 ░ watertight ground 6 and the
04-05-2019
2
cable 7, the transmitter circuit 8 ░ heat sink 9. The heat generating component 81 such as a
power FET which is included with the ceramic coating 10 etc. and further included in the
transmitter circuit 8 and is particularly high power type power FET is formed from the case of
the transmitter circuit 80 and the heat conductive insulating mounting member 82 Attached to 1.
Among these constituent items, those with the same reference numerals are the same as the
transmitter-receiver shown in FIG. 2, so detailed description thereof will be omitted. In the
embodiment of FIG. 1, the transmitter circuit 8 is housed inside the watertight case 1, and
further, the heat generating component 81 included in the transmitter circuit 8, in the case of
this embodiment, the power type PET, the thermal type such as aluminum nitride. The structure
is mounted on the watertight case 1 using a heat conductive insulating mounting member 82
utilizing a material having high conductivity and insulating properties. Further, the rubber cover
2 does not cover the entire exterior of the watertight case 1 and a part of the rubber cover 2 is
covered by the heat sink 9. The heat sink 9 is attached in intimate contact with a part of the
watertight case 1 and the ceramic coating 10 further includes a baking process about 10 ?m
thick over the ceramic coating area shown in FIG. 1 including the outside of the heat sink 9 It has
been subjected. With such a structure, heat generation by the heat generating component 81
such as a power type FET is caused by the thermally conductive insulating mounting member 82.
It is dissipated into water through the watertight case 1 and the heat sink 9. In this case, the
ceramic coating 1o forms a corrosion resistant structure for the heat sink 9 and the watertight
case IK, and the heat dissipation property is hardly impaired. In this manner, the transmitter
circuit can be stored in the watertight Couss internal pressure, and heat dissipation can be
realized with a simple configuration of each easy transducer. The above-described transducer
shown in FIG. 1 is merely an example of the present invention, and various variations are
possible. For example, the watertight case 1 may be a composite metal formed by an explosive
bonding method. However, in this case, the outer surface is a corrosion-resistant metal such as
stainless steel or copper alloy, and the inner surface is a metal having a good thermal
conductivity such as an aluminum alloy. In addition, the explosive bonding method is well known
recently as a method of bonding different metals by using explosive force of explosives in a state
of facing each other with a predetermined gap. In addition, an insulating oil such as silicone oil
may be filled in the watertight case 1 or a transmitting circuit or the like housed in the watertight
case l to utilize its thermal conductivity and insulating property. It is also apparent that the
method to be used to fill the watertight case 1 as a high thermal conductivity gas such as
hydrogen or helium is substantially the same. Furthermore, in the present embodiment, only the
transmission circuit is accommodated in the watertight case, but it is also possible to additionally
accommodate other desired electronic circuits such as the reception circuit, etc. It can be easily
implemented without loss.

According to the present invention as described above, according to the present invention, the
transmitter circuit is accommodated in the water-tight case of the transducer without using it in
the electronic circuit to be used, and the heat is generated underwater through the water-tight
case. The transmitter / receiver can reduce at least the layout space of the transmitter circuit and
the cooling facility, and can freely determine the beamforming characteristics when formed by
using multiple transmitters / receivers. There is an effect that it can be realized.
