Convection insulating board

Abstract

The invention discloses a convection insulating board, which is suitable for roofs or building envelops. The convection insulating board mainly comprises a lower end board and an upper covering board which is arranged above the lower end board, wherein an appropriate gap is formed between the upper covering board and the lower end board for forming a ventilation channel; and a plurality of vent pipes are arranged above the upper covering board. Under the condition of sunlight irradiation, solar radiant heat is absorbed by the vent pipes, so that the temperature and the density of air between the upper covering board and the lower end board change and an air buoyancy phenomenon is produced; simultaneously, a buoyancy effect is enhanced by ventilation pipelines of the vent pipes, so that air between the upper covering board and the lower end board flows outwards, external low-temperature air enters from the ventilation channel, natural convection is formed, heat inside the convection insulating board is brought away, heat is prevented from being transferred into the roofs or the building envelops, indoor load is lowered, indoor air conditioning load is lowered, and power consumption is lowered.

Description

【Technical field】 [0001] The invention relates to a convection heat insulation board, in particular to a convection type heat insulation board which can generate natural convection to reduce the heat introduced into the room. 【Background technique】 [0002] When the building shell is exposed to the sun, it will absorb heat and transmit it into the building, increasing the indoor temperature. The air conditioning system is needed to reduce the temperature. Therefore, the heat load of the building shell usually accounts for the majority of the air conditioning load, so it can effectively reduce the solar energy. Heat energy is introduced into the room, which is of great help to energy saving. [0003] The way to reduce solar heat into the room is to use heat insulation panels to cover the building shell to isolate heat conduction and reduce heat absorption, and the general design focuses on the strength or utilization of heat insulation panels. The intermediate filling materi...

[0003] The way to reduce solar heat into the room is to use heat insulation panels to cover the building shell to isolate heat conduction and reduce heat absorption, and the general design focuses on the strength or utilization of heat insulation panels. The intermediate filling material is used to cause thermal impedance. The existing technology uses the heat insulation board design of the intermediate filling material to fill the middle part of the insulating brick with materials such as Styrofoam or air to isolate heat conduction and reduce heat absorption, but limited effect
