Example Embodiment

[0021] Example one:

[0022] The present invention relates to a phase change insulation box, which includes a box body 11. The upper bottom surface, the lower bottom surface and the side walls of the box body 11 are respectively arranged with heat preservation structures, and the heat preservation structures are installed as modular structures. The thermal insulation structure on the upper and lower bottom surfaces of the box body 11 is a paraffin thermal insulation structure 12, which is a phase change material. The paraffin thermal insulation structure 12 includes paraffin microcapsules and thermal silica gel. The paraffin microcapsules and thermal silica gel are mixed and stirred evenly. The composite material obtained by mixing paraffin microcapsules and thermally conductive silica gel has high thermal conductivity, good thermal insulation effect, and can be reused many times.

[0023] The paraffin thermal insulation structure 12 includes a rectangular parallelepiped with a ca...

Example Embodiment

[0033] Embodiment two:

[0034] The difference between this embodiment and the first embodiment is that the heat preservation structure located on the side wall of the box 11 is a paraffin cylinder heat preservation structure, the paraffin cylinder heat preservation structure is a phase change material, and the paraffin cylinder heat preservation structure includes paraffin wax and thermally conductive silica gel, paraffin wax and The heat-conducting silica gel is evenly mixed and stirred, and the composite material obtained by mixing paraffin wax and heat-conducting silica gel has high guiding efficiency, good heat preservation effect, and can be reused many times. The composite material obtained by mixing is injected into the cavity of the rectangular parallelepiped, and the composite material of paraffin wax and thermally conductive silica gel is modularly designed as a cylindrical thermal insulation structure 13, which can avoid the poor thermal conductivity caused by directly...

Abstract

The invention discloses a phase change heat preservation box, a heat preservation testing method, and a manufacturing method of a heat preservation structure. The phase change heat preservation box comprises a box body. Heat preservation structures are arranged on the upper bottom surface, the lower bottom surface and the side walls of the box body respectively; the heat preservation structures located on the upper bottom face and the lower bottom face of the box body are paraffin heat preservation structures, while the heat preservation structures located on the side walls of the box body aren-tetradecane cylinder heat preservation structures or paraffin cylinder heat preservation structures; a plurality of columnar holes used for containing the heat preservation structures are formed inthe side walls of the box body. A heat preservation structure is modularly designed on the box body, the heat conduction efficiency is improved, the heat preservation effect is improved, replacementis convenient, the box body can be repeatedly used, cost is effectively saved, and the heat preservation box is reasonable in structure and can be widely applied to the technical field of heat preservation boxes.

Description

technical field [0001] The invention relates to the technical field of heat preservation boxes, in particular to a phase change heat preservation box, a heat preservation test method and a method for making a heat preservation structure. Background technique [0002] With the gradual popularization of online shopping, people shop more and more types on the Internet, gradually extending from the initial clothing and electronic products to food, medicine, cosmetics and other fields, basically covering all the items people need in life. The continuous development of logistics and transportation is required to meet the transportation requirements of increasingly diversified online shopping commodities. Inexpensive thermal insulation materials have mediocre thermal insulation effects and cannot meet the harsh transportation requirements, while aerospace-grade thermal insulation materials with good thermal insulation effects are expensive. The cost of such materials is currently h...
