Heat preservation sleeve for heat insulation of heating pipeline

Abstract

The invention discloses a heat preservation sleeve for heat insulation of a heating pipeline, and belongs to the technical field of heating and heat preservation. A plurality of light-transmitting covers are distributed on the outer wall of an outer heat insulation sleeve with a heat insulation effect and used for transmitting light and collecting heat, and when a memory thermal deformation body thermally deforms to a spring state due to high temperature, heat conduction columns are pulled to move to the light-transmitting covers. Therefore, light and heat are transmitted to an inner heat conduction sleeve through the heat conduction columns and telescopic heat conduction rods, and the solar heat energy is stored. When the external temperature is lowered, the memory thermal deformation body recovers to the low-temperature initial state, the heat conduction columns are pushed to return to the inner end of the heat storage cavity, and at the moment, a pair of elastic heat insulation petals oppositely reset and are combined under the elastic action of the elastic heat insulation petals. On one hand, heat at the heat conduction columns is sealed at the joint of the heat storage cavity and the inner heat conduction sleeve, heat dissipation is prevented; and on the other hand, external low temperature is prevented from being transmitted inwards through the light-transmitting covers, the internal and external heat insulation effect is achieved, and heat transmission of the heat insulation sleeve to the heating pipeline and the heat insulation effect are achieved.

Description

technical field [0001] The invention relates to the technical field of heating and heat preservation, and more specifically relates to a heat insulation cover for heating pipes. Background technique [0002] Heating pipes In order to avoid heat loss inside the heating pipes due to low external air temperature or heat loss due to heat exchange with the air when the temperature is low, it is necessary to install an insulation device for the heating pipes. [0003] The current heating pipe insulation device generally uses on-site manual splicing of insulation layers on the outside of the heating pipes. Common insulation layers include polyurethane and glass wool. However, a single layer of heat insulation is wrapped around the pipe, which has a limited thermal insulation effect. For some heating pipes installed on the ground, they are more seriously affected by changes in the external environment temperature. Generally speaking, they are hot and cool quickly.

Problems solved by technology

However, a single layer of heat insulation is wrapped around the pipe, which has a limited heat preservation effect. For some heating pipes installed on the ground, they are more seriously affected by changes in the external environment temperature. Generally speaking, they are hot and cool quickly. It is also fast, and the heat insulation effect is poor, and it is impossible to better store the heat energy of the external environment such as the sun's heat in a hot environment.
