a hot water bag

Abstract

A novel phase-change insulation hot water bag is characterized by comprising three layers, from outside to inside, including an outer layer, an interlayer and an inner layer, a cavity between the outer layer and the interlayer is filled with carbon dioxide, a cavity between the interlayer and the inner layer is filled with alcohol, the inner layer is filled with heat-storing salt solution, an electric heater rod is arranged in the heat-storing salt solution, and the electric heater rod is connected with a power plug through a wire.

Description

technical field [0001] The invention relates to a phase change heat preservation hot water bag which integrates different boiling points of liquids, latent heat of phase change of alcohol and heat preservation principle of interlayer of greenhouse gas, and belongs to the invention and creation in the field of energy saving of daily necessities. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, ordinary people have paid more and more attention to the quality of life, so the requirements for the use of various items are also increasing. In addition to focusing on the beautiful appearance of the items, more emphasis is placed on their functionality. Performance. As far as daily heat preservation and heating hot water bags are concerned, achieving long-term heat preservation is of great significance to energy saving and low-carbon economy. [0003] The existing hot water bag heats the heat-prone materi...

AI Technical Summary

Problems solved by technology

But its design has the following shortcomings, one is that the phase change material directly absorbs the heat of the heating element and then indirectly transfers it to the heat storage liquid, so the temperature of the water rises slowly; Boiling point needs to be higher than heat storage liquid to operate efficiently

Third, there is no specific explanation for the security
