Temperature adjustment method for inner-outer-wall-structured heat preservation device and heat preservation device implementing temperature adjustment method

Abstract

The invention provides a temperature adjustment method for an inner-outer-wall-structured heat preservation device and the heat preservation device implementing the temperature adjustment method, relating to a method for transferring heat between inner and outer walls in a sealing cavity of the heat preservation device and further relating to a multifunctional heat preservation device with heating and cooling functions. The heat preservation device comprises an outer wall (1), an inner wall (2), a controllable heat transfer medium (3), a heat transfer boss (4) and a limiting structure (7). Under a heat preservation state, the heat transfer medium (3) is only in contact with the outer wall (1) or the inner wall (2), and a thermal insulation state is formed between the inner and outer walls in the heat preservation device. Under a heat dissipation state, the heat transfer medium (3) is fit with the heat transfer boss (4) between the inner and outer walls of the heat preservation device, and heat is transferred through the inner wall (2), the heat transfer boss (4), the heat transfer medium (3) and the outer wall (1). Under the action of the limiting structure, the heat preservation device can be in a reliable heat preservation or heat dissipation state no matter when the heat preservation device is placed upwards, downwards, obliquely and transversely or when the people move. The heat preservation device provided by the invention has a reliable heat preservation function and is capable of heating and cooling under a sealing state, so that the pollution of liquid to air is avoided, and meanwhile, sprinkling and scalding are prevented; and the heat preservation device can be used as a warming device in cold winter.

Description

technical field [0001] The invention relates to a method for adjusting the temperature of a heat-preservation appliance with an inner and outer wall structure, including a heat transfer method between the inner and outer walls of the cavity of the heat-retention appliance. [0002] The invention also relates to a temperature-adjustable multifunctional thermal insulation appliance, which includes an outer wall, an inner wall, a heat transfer medium, and the like. It is characterized in that the heat-transfer medium between the inner and outer walls of the heat-preservation appliance is in a controlled state, so as to realize reliable heat preservation and heat dissipation. Background technique [0003] In real life, throughout the year, especially in the hot summer or cold winter, people are accustomed to using thermal insulation appliances to keep the temperature of objects, and the vacuum thermal insulation appliances with inner and outer wall structures have a better therm...

Problems solved by technology

Chinese Invention Patent Publication (CN204520141U) discloses a method for realizing the heating and cooling function of a vacuum heat preservation appliance, but there are also the following disadvantages: because one end of the metal sheet is a free end, it can only be placed in a stationary and upright state (upright or upside down). ) is the best state of heat preservation and heat dissipation; when tilted, placed horizontally, or in motion, the metal sheet is in an uncontrolled state, and the free end of the metal sheet is sometimes in contact with the shell and sometimes disconnected, which affects the heat preservation and heat dissipation performance.
