Hollow composite bottom pot and manufacturing method thereof

Abstract

The invention discloses a hollow composite bottom pot and a manufacturing method thereof, the hollow composite bottom pot comprises a pot body, an outer pot body, an inner pot body, a heat-conducting medium and a supporting body, the bottom of the outer pot body and the bottom of the inner pot body are connected through the supporting body, and the outer pot body, the inner pot body and the supporting body are integrally machined and formed; the pot body and the inner pot body are integrally formed; a cavity without a supporting body at the joint of the outer pot body and the inner pot body is a medium bin, a plurality of heat conduction holes are formed in the supporting body, the heat conduction holes are communicated with the medium bin to form a sealing cavity, and a heat conduction medium is injected into the sealing cavity; and energy on the outer pot body transfers heat to the inner pot body through the support body and the heat-conducting medium. In order to improve the heat transfer speed of the pot body and reduce the waste of heat energy, heat conducted on the outer pot body by an induction cooker or liquefied gas is transferred to the inner pot body through the support body and the heat-conducting medium. Heat on the outer pot body is transferred to the inner pot body and the heat-conducting medium through conduction of the supporting body, and heat on the outer pot body is transferred to the inner pot body through convective heat transfer of phase change of the heat-conducting medium.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a hollow composite bottom pot and a manufacturing method thereof. Background technique [0002] At present, the bottom of the composite pot is a multi-layer solid composite bottom made of stainless steel. The center of the bottom of the pot may turn red due to high temperature, and the center of the bottom of the pot will become a hot spot of high temperature. The thermal expansion under the condition of uneven heat conduction causes the stress of different materials in the bottom of the multi-layer pot to be very large, and the different thermal expansion coefficients of different materials cause creeping and cracking or desoldering, and the thermal expansion of different materials causes unevenness in the bottom of the pot. The processing technology of the composite bottom pot is complicated, the production efficiency is low, and the processing cost is high; the weight of the co...

AI Technical Summary

Problems solved by technology

At present, the heat pipe technology has been applied to the composite pot. The heat transfer chamber of the composite bottom pot is composed of multiple materials. The expansion rate of the composite bottom pot made of heterogeneous materials is different at high temperature, which may easily cause the deformation of the pot body.
