Method for preparing double-layer heat-uniformizing pot

Abstract

The invention relates to a method for preparing a double-layer heat-uniformizing pot. The method comprises the steps that an inner pot and an outer pot are prepared; the outer side of the inner pot and / or the inner side of the outer pot are / is coated with a metal powder glue layer, and pressing, baking and sintering are performed; the inner pot is sleeved with the outer pot, the tops of the inner pot and the outer pot are sealed and fixedly connected, and a heat conduction cavity is formed between the inner pot and the outer pot; air in the heat conduction cavity is extracted from a vacuumizing hole formed in the outer pot, so that the heat conduction cavity is in a negative pressure state, a liquid phase change working medium is injected through the vacuumizing hole, and the vacuumizing hole is sealed. A porous metal layer is manufactured through the method. The porous copper layer can ensure that after the liquid phase change working medium is volatized into gas, the gas is passed to the condensed end at the top of the heat conduction cavity to be diffused, cooled liquid flows along the porous copper layer to the bottom of the heat conduction cavity and is heated again and evaporates, the heating process is repeated, and it is ensured that the temperature field at each part of the whole inner pot is basically kept consistent.

Description

technical field [0001] The invention relates to a double-layer soaking pot and a preparation method, belonging to the field of double-layer soaking pots. Background technique [0002] At present, the inner tank of electric rice cooker or pressure cooker that can be heated by electromagnetic is generally made of aluminum-stainless steel composite plate or aluminum-stainless steel double-bottomed steel plate, which is usually achieved by spraying non-stick coatings such as PTFE (Teflon) on the inner aluminum surface. The non-stick effect of its surface during cooking. However, these non-stick coatings have poor wear resistance and are relatively easy to fall off. After being absorbed by the human body, they may cause safety hazards to the health of consumers. How to achieve a pan body that does not need to spray PTFE to achieve uniform heating and prevent sticking is an art in the art Problems that technicians urgently need to solve. Contents of the invention [0003] The ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a preparation method of a double-layer soaking pot, which overcomes the uneven heating of the pot body in the prior art that causes easy sticking to the pot or the inner wall of the pot is sprayed with PTFE to achieve a non-stick effect, but it is easy to fall off and thus Defects that cause safety hazards to human health
