Quick-freezing unfreezing plate and refrigerator

Abstract

The invention discloses a quick-freezing unfreezing plate and a refrigerator. The quick-freezing unfreezing plate comprises a shell, a heat tube, a wire tube metal mesh, a cold storage agent and a graphene nano composite material layer, wherein the heat tube is installed inside the shell and is used for heat conduction, the wire tube metal mesh is wound on the heat tube, the cold storage agent isfilled inside the shell and corresponds to the periphery of the heat tube and the wire tube metal mesh, and the graphene nano composite material layer is arranged above the shell and is used for heatconduction or cold conduction. According to the quick-freezing unfreezing plate and the refrigerator, the heat storage (cold storage) material structure is added around the heat pipe, the phase changeof the material is used for absorbing or releasing heat, the continuous cooling amount (heat) is provided for food freezing (unfreezing), the time required for freezing (unfreezing) is shortened, andthe quick-freezing unfreezing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a quick-freezing and thawing plate with cold storage and rapid heat conduction functions and a refrigerator. Background technique [0002] The quick freezing and thawing of frozen food can keep the freshness of the food to the maximum extent, and it has always been an important technology that the refrigerator industry pays attention to. The industry adopts a variety of methods to achieve it, among which is the use of heat pipe cooking trays to achieve food fast. Freezing and thawing, the heat (cooling capacity) of the food is quickly dissipated to the surroundings through the heat conduction tube to achieve the purpose of rapid freezing (thawing). [0003] However, because the cold energy (or heat) accumulated in the cooking plate material itself is too small, there is a problem that the effect is good at the beginning but the persistence is poor during the quick freezing ...

AI Technical Summary

Problems solved by technology

[0003] However, because the cold energy (or heat) accumulated in the material of the cooking plate itself is too small, there is a problem that the initial effect is good during the quick freezing or thawing process, but the persistence is poor. After a while, the process is slow and the efficiency is poor.
