Battery pack and cooling device for UUV (Unmanned Underwater Vehicle)

Abstract

The invention discloses a battery pack for a UUV (Unmanned Underwater Vehicle) and a cooling device, and relates to the technical field of battery pack heat dissipation. The cooling device comprises a front heat dissipation end plate, a front capillary tube welding plate, a cooling capillary tube, a rear capillary tube welding plate and a rear heat dissipation end plate, cooling fins are arranged on the outer side of the front heat dissipation end plate, a communication water channel is milled in the inner side of the front heat dissipation end plate, and one end of the cooling capillary tube is fixed through the front capillary tube welding plate and communicated through the communication water channel of the front heat dissipation end plate; radiating fins are arranged on the outer side of the rear radiating end plate, communicating water channels are milled on the inner side of the rear radiating end plate, and the other ends of the cooling capillary tubes are fixed through a rear capillary tube welding plate and are communicated through the communicating water channels of the rear radiating end plate; the cooling capillary tube penetrates through the unit battery of the UUV, and the penetrating direction of the cooling capillary tube is the same as the axial direction of the single battery in the unit battery. According to the invention, cooling of the UUV battery pack can be realized under a relatively high-rate discharge working condition.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of battery packs, in particular to a battery pack and a cooling device for UUV. Background technique [0002] At present, the existing small UUV battery packs are usually installed in a mine section with a compact space. There is no space to install a fan in the section, and the battery pack is cooled by air cooling, so the natural cooling method is basically adopted. When the battery pack is discharged at a higher rate, it will cause short-term overheating of the battery pack, which may cause thermal runaway of the single battery, and cause serious consequences such as combustion and explosion of the entire battery pack. Contents of the invention [0003] The invention provides a battery pack and a cooling device for UUV, in order to solve the problem of short-term overheating of the battery pack in the prior art when the battery pack is discharged at a higher rate. [0004] In order ...
