Problems solved by technology

[0006] The above two design schemes are battery installation schemes applied to electric vehicles, not suitable for underwater vehicle battery installations, and both schemes have deficiencies
Although the first solution uses phase-change materials to absorb heat, it only dissipates heat through the ventilation holes and cannot quickly discharge the heat from the entire battery device.
Although the second solution uses heat pipes to take heat out of the battery device, the air-cooled device is not suitable for the narrow space of the underwater vehicle, and the efficiency is low

Abstract

The invention discloses a battery device for an underwater vehicle. The device comprises a water-cooling tank, a battery tank, a battery rack, a battery and a heat pipe, wherein a battery pack is fixed on the battery rack made from aluminum-based ABS engineering plastic in the battery tank, and is arranged in battery holes in the battery rack; heat pipe holes are distributed in the gaps among thebattery holes, and are used for assembling cooling heat pipes; the space separated by the battery rack and the battery tank is filled by a phase-change material; the water-cooling tank is arranged atthe upper end of the battery tank, and is provided with heat pipe holes which are corresponding to sizes and positions of the heat pipes of the battery tank and are sealed, and one end of a heat pipeis inserted into the heat pipe hole of the water-cooling tank; a water inlet and a water outlet are formed in the water-cooling tank to complete water-cooling circulation. The battery device is used for cooling a phase-changing material and integrating efficient heat pipe radiation and water-cooling radiation, the actual situation of underwater vehicle application is sufficiently taken into consideration for assembly and maintenance, and safe operation of the power battery of the underwater vehicle can be efficiently guaranteed.

Description

technical field [0001] This patent relates to the field of underwater vehicles, especially the field of battery devices for underwater vehicles. Background technique [0002] With the huge demand for my country's ocean development strategy and sea rights maintenance, various types of water and underwater marine vehicles have developed rapidly. New electric powered underwater vehicles have gradually replaced traditional thermodynamic underwater vehicles because of their advantages such as low noise, no track, and large flight depth. In order to meet the power requirements of an underwater vehicle, its power source usually consists of a large number of high-energy batteries connected in series / parallel. [0003] The underwater vehicle power battery device will produce energy accumulation effect during the long-term high-current discharge process, which will have a very serious impact on the safe use of the battery device. The heat accumulation effect will cause the battery t...
