Description

Technical Field

[0001] This utility model relates to the field of unmanned vessel technology, and in particular to a heat dissipation structure for an unmanned vessel. Background Technology

[0002] Unmanned surface vessels (USVs) are intelligent unmanned platforms that achieve surface operations through autonomous navigation or remote control, integrating technologies from multiple disciplines such as marine engineering, artificial intelligence, communication technology, and sensor integration. Existing USVs are in close contact with water during operation, therefore their interiors require excellent sealing to prevent water from directly entering and damaging the internal electronic components. Consequently, the power unit inside the USV generates a significant amount of heat during operation, severely impacting its reliability and shortening its lifespan. Therefore, technologies for cooling the power unit mounted on the hull have been developed, as illustrated in Chinese Utility Model Patent Publication No. CN205323225U—which involves installing cooling fins on the drive shaft to solve the problem of excessively high temperatures caused by the power unit operating in a sealed environment.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] Reference Figure 1-11 As shown, the heat dissipation structure of the unmanned boat of this utility model includes: hull 1, heat-conducting metal block 2, and power unit 3.

[0019] The hull 1 has an inlet 11 and an outlet 12 on its inner bottom wall; The heat-conducting metal block 2 is fixed inside the hull 1 and covers the water inlet 11 and the outlet 12; The power unit 3 includes a motor 31 placed on a heat-conducting metal block 2.

[0020] The heat dissipation structure of the unmanned boat provided by this utility model is achieved by setting an inlet 11 and an outlet 12 inside the hull 1, and simultaneously equipping the motor 31 on a metal heat-conducting block, so that when the product is operating on water, the heat generated by the motor 31 in the power unit 3 is directly conducted to the heat-conducting metal block 2 to achieve heat dissipation.

[0021] In addition, during the forward movement of the hull 1, water first enters through the inlet 11 and then exits through the outlet 12, thus forming a water flow path. That is to say, when the product is operating on water, the heat generated by the motor 31 is conducted to the heat-conducting metal sheet. Since the heat-conducting metal sheet covers the outlet 12 and the inlet 11, the water also has a cooling effect on the heat-conducting metal sheet.

[0022] It is worth noting that the aforementioned water inlet 11 is opened towards the bow of the ship; the drainage outlet 12 is opened towards the stern of the ship; the heat-conducting metal sheet is made of a metal material with excellent thermal conductivity, such as silver, copper, gold, aluminum, etc.

[0023] Furthermore, a raised ring 13 is integrally formed on the outer circumference of the inner bottom wall of the hull 1, surrounding the water inlet 11 and the outlet 12; Both the inlet 11 and the outlet 12 are located in the inner diameter direction of the convex ring 13; The heat-conducting metal block 2 is glued to the convex ring 13 to seal the upper opening of the convex ring 13, thereby forming the heat exchange cavity 14.

[0024] Specifically, by setting a convex ring 13 and gluing the heat-conducting metal block 2 onto the convex ring 13, the heat-conducting metal block 2 glued onto the convex ring 13 forms a heat exchange cavity 14 after assembly. The gluing assembly method avoids water in the heat exchange cavity 14 from entering the hull 1 and affecting electronic devices and other components.

[0025] It is worth noting that the adhesive required for assembling the thermally conductive metal block 2 and the convex ring 13 in this invention can be a commercially available and mature structural adhesive, such as an organosilicon structural adhesive with a temperature resistance range of -60℃ to +300℃; or an epoxy resin structural adhesive; or a phenolic resin structural adhesive. This invention includes, but is not limited to, the adhesives required for assembling the thermally conductive metal block 2 and the convex ring 13. For example, inorganic high-temperature resistant adhesives and other structural adhesives with adhesive and temperature resistance properties can also be used. Those skilled in the art can select the appropriate adhesive according to actual needs.

[0026] Furthermore, the power unit 3 also includes a base shaft 32 and fan blades 33; One end of the bottom shaft 32 is fixedly connected to the output shaft of the motor 31 inside the hull 1, and the other end of the bottom shaft 32 extends out of the outside of the hull 1 and is located at the bottom of the rear end of the hull 1. The fan blade 33 is fixed to the other end of the base shaft 32.

[0027] Specifically, when the motor 31 is working, its output shaft drives the bottom shaft 32, which is fixedly connected to it, to work, which in turn causes the fan blades 33 to work.

[0028] Furthermore, it also includes a storage battery 4, which is fixedly installed inside the hull 1 and electrically connected to the motor 31.

[0029] Specifically, battery 4 provides energy for this product.

[0030] Furthermore, the side wings of the hull 1 are integrally formed with a cavity 15, and the hull 1 is also provided with an exhaust port 16 connected to the cavity 15.

[0031] Specifically, when the product capsizes during operation on the water surface, water enters the cavity 15 through the opening of the cavity 15 on the side of the hull 1 to achieve counterweight. When the water enters the cavity 15, the gas in the cavity 15 is drained through the drain port 12. Then, the motor 31, bottom shaft 32 and fan blade 33 in the power unit 3 work to generate torque force, which achieves the effect of self-turning.

[0032] It is worth noting that the cavity 15 is only located on the side wing of any side of the hull 1.

[0033] Furthermore, it also includes a fastening assembly 5, which includes a clamp 51 and a mounting screw 52; The inner bottom wall of the hull 1 has a screw post, which is located on one side of the convex ring 13. The threaded end of the mounting screw 52 passes through the clamp 51 and is threadedly connected to the screw post (shown in the figure but not marked).

[0034] Specifically, the threaded end of the mounting screw 52 allows the clamp 51 to press against the body of the motor 31, enabling the motor 31 to better cooperate with the heat-conducting metal block 2 and achieve excellent heat conduction. That is, if there is a loose gap between the body of the motor 31 and the heat-conducting metal block 2, the heat conduction effect will be reduced.

[0035] It is worth noting that the clamp 51 may be made of metal or high-temperature resistant plastic.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
