Abstract

The invention discloses a metal reflective warming plate. The metal reflective warming plate comprises a thermal insulation casing and several stacked metal reflection foil sheets coated with the thermal insulation casing. Each one of the several stacked metal reflection foil sheets is provided with several raised first ribs arranged along a first direction and several raised second ribs arranged along a second direction, the first ribs and the second ribs are staggered and extend to form several rhombic unit arrays, the rhombic units of each two adjacent metal reflection foil sheets form an included angle of 90 degrees, the raised first ribs and second ribs of each two adjacent metal reflection foil sheets are staggered oppositely, and several relatively-independent air sandwich chambers are formed between each two adjacent metal reflection foil sheets. The metal reflective warming plate utilizes the metal reflection foil sheets of the rhombic unit structures, and the air layer between each two adjacent metal reflection foil sheets is divided into narrow spaces so that air natural convection heat transfer between the metal reflection foil sheets can be effectively inhibited.

Description

technical field [0001] The invention relates to a metal reflective heat preservation plate, especially a metal reflective heat preservation plate with good heat preservation effect, which can be used to construct a metal reflective heat preservation system for nuclear power plant equipment and pipelines, so as to ensure that the equipment and pipelines are in normal operation Reduce heat loss under working conditions and realize heat preservation function. Background technique [0002] Under normal operating conditions of a nuclear power plant, there is a large difference between the temperature of various equipment and pipelines and the external ambient temperature. For example, the average temperature of the coolant in the primary circuit of the nuclear island is generally higher than 310°C, while the external ambient temperature is generally required to be less than 50°C. Therefore, in order to ensure that the equipment and pipelines in the nuclear power plant reduce hea...
