Abstract

The invention discloses a vacuum thermal insulation component, which comprises a thermal insulation core plate, a first support plate, a second support plate, and a blocking film bag, wherein the first support plate is arranged on the upper surface of the thermal insulation core body, the second support plate is arranged on the lower surface of the thermal insulation core body, the first and the second support plates are used for supporting the thermal insulation core body, and a cavity is formed between the first and the second support plate; and the thermal insulation core body and the first and the second support plates are hermetically arranged in the blocking film bag, and the interior of the blocking film bag is vacuum. The vacuum thermal insulation component provided by the invention has excellent thermal insulation performance.

Description

technical field [0001] The invention relates to a vacuum heat insulation component, a preparation method of the vacuum heat insulation component and a refrigeration device comprising the vacuum heat insulation component. Background technique [0002] There are three modes of heat transfer: conduction, convection and radiation. If you want to reduce the heat transfer, you need to reduce the heat transfer in the above three ways. Among them, radiation heat transfer has a greater influence on heat transfer at high temperature, but has less influence on heat transfer at normal temperature. The current common insulation methods are all improved by reducing the conduction and convection thermal conductivity of the material. Existing vacuum insulation panels achieve high thermal insulation performance by greatly reducing their conduction and convection. The interior of the vacuum insulation panel is filled with low thermal conductivity thermal insulation material, and the exteri...
