Description

Technical Field

[0001] The invention relates to the technical field of underwater acoustic transducers, and in particular to a transducer heat dissipation method. Background Art

[0002] With the deepening of the development of marine resources and the rapid development of marine military, the scope of human activities in the ocean is expanding, and ocean-related detection technologies are becoming more and more important. Sonar technology, as the main technology for ocean detection, has developed rapidly and has been widely used in military submarines, offshore oil surveys, seabed geomorphology surveys and other fields.

[0003] The transmitting transducer has high power and will generate internal heat when working for a long time. The rapid increase in temperature will cause changes in the transducer parameters and gradually change the matching state, and will also lead to deterioration of the performance of piezoelectric ceramics. Therefore, cooling the transducer is necessary to maintain long-term stable operation. Summary of the invention

[0004] The object of the present invention is to provide a transducer heat dissipation method to solve the problems in the background technology.

[0005] In order to solve the above technical problems, the present invention provides a transducer heat dissipation method, comprising the following steps:

[0006] Cut the heat-resistant silicone tube according to the size and number of the vibrators in the transducer;

[0007] Arrange the heat-resistant silicone tube in the internal gap space of the vibrator;

[0008] Seal and connect the two ends of the heat-resistant silicone tube to the metal joints respectively;

[0009] Insert the metal connector into the hole of the transducer housing;

[0010] The whole is sealed by a perfusion layer.

[0011] In one embodiment, the heat-resistant silicone tube is evenly arranged in the arrangement gap of the vibration element.

[0012] In one embodiment, the heat-resistant silicone tube has an inlet and an outlet at both ends, respectively, and there is a liquid level difference between the inlet and the outlet, thereby generating a pressure difference between the inlet and the outlet, allowing the heat-conducting medium to flow between the heat-resistant silicone tube and the external water area to transfer heat.

[0013] In one embodiment, there is a temperature difference between the internal space of the transducer and the external water area.

[0014] The present invention provides a transducer heat dissipation method, wherein the heat-resistant silicone tube is evenly arranged in the available space inside the transducer, withstands the temperature of the transducer during high-temperature curing, and has excellent insulation performance. The heat-conducting medium is determined by the external medium, and there is no need to fill special heat-conducting medium materials. There is a temperature difference between the internal space of the transducer and the external water area. When the transducer is actually used, there is a liquid level difference between the water inlet and the water outlet, thereby generating a pressure difference between the water inlet and the water outlet, allowing the medium to flow between the hose and the external water area, thereby transferring heat.

[0018] The following is a further detailed description of a transducer heat dissipation method proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0019] In view of the heat dissipation requirements of the above transducer, the present invention provides a method that is simple to manufacture and has reliable heat dissipation. Figure 1 As shown, the specific content of the present invention is that the heat-resistant silicone tube 3 is evenly laid in the arrangement gap of the array element 1, the water inlet and the water outlet of the heat-resistant silicone tube 3 are connected to the external water area through a metal joint 4 respectively, and the liquid medium forms a loop through the water inlet and the water outlet, bringing the heat of the internal space to the external water area, thereby cooling the transducer.

[0020] The operating method of the above-mentioned transducer heat exchange mode comprises the following steps:

[0021] (1) According to the size and number of the vibrator 1 in the transducer, cut the heat-resistant silicone tube 3 to the corresponding size.

[0022] (2) The heat-resistant silicone tube 3 is evenly arranged in the internal gap space of the vibration element 1.

[0023] (3) The two ends of the heat-resistant silicone tube 3 are sealed and connected to the metal joint 4 through rubber sealing rings. Figure 2 As shown,

[0024] (4) Insert the metal connector 4 into the hole of the transducer housing 2.

[0025] (5) The whole is sealed by a perfusion layer, such as Figure 3 shown.

[0026] The biggest feature of the present invention is that the heat-resistant silicone tube is relatively soft and can be evenly arranged in the available space inside the transducer. It can withstand the temperature of the transducer during high-temperature curing and has excellent insulation performance. The heat-conducting medium is determined by the external medium and there is no need to fill special heat-conducting medium materials. There is a temperature difference between the internal space of the transducer and the external water area. When the transducer is actually used, there is a liquid level difference between the water inlet and the water outlet, thereby generating a pressure difference between the water inlet and the water outlet, allowing the medium to flow between the hose and the external water area, thereby transferring heat.

[0027] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
