Abstract

The invention provides a heat dissipation device for a heating assembly in a closed environment and a battery compartment of an underwater vehicle, and solves the problem that an existing common heat dissipation mode is poor in heat dissipation effect or has adverse effects on the work of a battery pack and the work of the underwater vehicle. The heat dissipation device for the heating assembly in the closed environment comprises a control unit, a vibration exciter, a connecting assembly, a first elastic vibration film and a second elastic vibration film. The first elastic vibration film and the second elastic vibration film are located on the two sides of the heating assembly respectively to form a closed space, and the heating assembly is contained in the closed space. The vibration exciter is arranged outside the closed space and provides axial reciprocating vibration force for the first elastic vibration film through the connecting assembly under the control of the control unit, so that gas in the closed space circularly flows; and the vibration frequency and amplitude of the first elastic vibration film and the second elastic vibration film are determined according to a low-order modal shape spectrum, and resonance with other components is avoided.

Description

technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a heat dissipation device for heating components in a closed environment and a battery compartment of an underwater vehicle. Background technique [0002] The use of underwater vehicles to detect and develop marine resources has been widely used in scientific research, military and industrial fields. The power required by underwater vehicles is generally provided by electric propulsion systems. In order to meet the power requirements of underwater vehicles, a large number of batteries with high specific power and high specific energy need to be connected in series-parallel and installed in groups on underwater vehicles. In the battery compartment; however, the battery compartment of the underwater vehicle is in a closed environment for a long time during the working process, and the batteries continuously generate heat due to Joule heat and entropy change fact...
