Visible light transparent radiation heat dissipation assembly

Abstract

The invention provides a visible light transparent radiation heat dissipation assembly. The visible light transparent radiation heat dissipation assembly comprises a visible light transparent radiation heat dissipation outer layer arranged at the outer side of a thermal management target and a visible light transparent radiation cold insulation inner layer arranged at the inner side of the thermal management target. According to the visible light transparent radiation heat dissipation assembly, the color and pattern of the thermal management target are reserved, efficient heat dissipation of a corresponding cavity is achieved, the refrigeration heat loss of the corresponding cavity is reduced, and the visible light transparent radiation heat dissipation assembly can be applied to building and vehicle energy saving and the like.

Description

technical field [0001] The invention belongs to the technical field of heat management system design, and in particular relates to a visible light transparent radiation heat dissipation component. Background technique [0002] Air conditioning energy consumption accounts for about 37% and 20% of the energy consumption of vehicles and buildings. Taking these chambers as an example, in summer, the main causes of high air-conditioning energy consumption include the absorption of sunlight by the internal objects through the windows and the absorption of sunlight by the painted outer layer (thermal management target). The outer layer of the chamber absorbs about 20% to 95% of the incident solar energy and converts it into heat, causing a thermal load on the chamber. Radiative heat transfer accounts for approximately 26% to 50% of the heat load caused by the outer layers of the chamber. In the traditional research on building energy saving, there are schemes such as using radiat...

Problems solved by technology

In the traditional research on building energy saving, there are schemes such as using radiation blocking aluminum foil (Radiant barrier or Reflective insulation) or silver / white radiation heat dissipation coating to reduce the heat input into the chamber from the thermal management target, because the aluminum foil and radiation heat dissipation coating are beautiful This type of radiation cooling system cannot be directly applied to the inner and outer surfaces of the chamber for efficient cooling of compatible colors
