Description

Technical Field

[0001] This utility model relates to the field of heating devices, specifically a heating device for polar life rafts. Background Technology

[0002] A life raft is a non-self-propelled vessel used for emergency rescue on board. It is typically equipped with a certain amount of food and fresh water for the crew while adrift at sea awaiting rescue. Life rafts are classified into two types based on their structure: rigid life rafts and inflatable life rafts. Rigid life rafts are constructed primarily of rigid materials, while inflatable life rafts are mainly made of rubber and nylon fabric. Life rafts are designed to withstand prolonged exposure and afloat in various sea conditions and to function safely and normally after being deployed from a certain height.

[0003] Polar life rafts are lifesaving devices specifically designed for use in extreme polar environments. Due to the extremely low temperatures in polar regions, ordinary life rafts may not be able to maintain their structural integrity and functionality under these conditions. Therefore, polar life rafts are typically equipped with special insulation and heating systems to ensure normal operation even at temperatures as low as -55°C. The polar life raft heating device is a device specifically designed for operation in extremely low-temperature environments. It ensures that the life raft remains operational in the frigid conditions of polar waters. In low-temperature conditions, it is not only necessary to rely on the cold-resistant properties of the polar life raft itself, but also to ensure that the storage tank and its internal release mechanism are not damaged by the low temperatures. It is also necessary to prevent the equipment from freezing and affecting release. During the heating process, the heating temperature also needs to be controlled to prevent excessively high temperatures from damaging the equipment. Utility Model Content
