Heat preservation container capable of quickly transferring heat and preparing method of heat preservation container

Abstract

The invention relates to a heat preservation container capable of quickly transferring heat and a preparing method of the heat preservation container. The heat preservation container capable of quickly transferring heat comprises a hot container, a cold container and a shell wrapping the outer surfaces of the two containers. A vacuum cavity is defined by the hot container, the cold container and the shell. The lower half part of the vacuum cavity is filled with a heat transfer medium, and the height of the heat transfer medium in the vacuum cavity is lower than the bottom of the hot container. The preparing method comprises the steps that the containers are welded to the shell, a process opening is reserved, and the sealed cavity is formed by the shell and the outer surfaces of the containers; the sealed cavity is vacuumized through the process opening, and the heat transfer medium is injected into the cavity through the process opening after vacuumizing is finished, wherein the height of the heat transfer medium in the vacuum cavity is lower than the bottom of the hot container; the process opening is sealed. The heat preservation container can preserve heat and can also quickly transfer heat through the phase change of the heat transfer medium, the heat transfer time is greatly shortened, and cooling is fast; the preparing method is simple, and the processing cost is low.

Description

technical field [0001] The invention relates to the field of household utensils, in particular to a thermal insulation container capable of rapid heat transfer and a preparation method thereof. Background technique [0002] At present, in real life, it often occurs that after pouring boiling water, it cannot be directly used, and there is a lack of rapid and effective cooling methods. Patent: ZL201410367161.4 proposes a method for rapidly cooling high-temperature liquids through heat storage materials, and mentions a liquid metal. Considering that the specific heat capacity of metal is much lower than that of water, in order to meet its practical use, it needs Liquid metal with multiple volumes is heavy and expensive to carry. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a thermal insulation container capable of rapid heat transfer and a preparation method thereof, which can not only maintain r...
