Radiant heat exchange plate component

Abstract

The invention provides a radiant heat exchange plate component. The radiant heat exchange plate component comprises a metal radiant plate, a heat exchange component and an outer cover. A nonmetal heat conduction layer is arranged between the metal radiant plate and the heat exchange component. The heat exchange component and the metal radiant plate contact with the upper side and the lower side of the nonmetal heat conduction layer respectively. Through heat conduction of the nonmetal heat conduction layer arranged between the metal radiant plate and the heat exchange component, heat resistance between the metal radiant plate and the heat exchange component can be reduced; through surface heat conduction, the metal radiant plate can acquire an uniform temperature field, so that low temperate of the surface of the metal radiant plate can be maintained through proper increase of water temperature of an refrigerant water inlet in a refrigeration working condition (or high temperature of the surface of the metal radiant plate can be maintained through proper reduction of the water temperature of the refrigerant water inlet in a heating working condition), and working efficiency of a heat pump unit can be improved.

Description

technical field [0001] The present invention relates to the field of air conditioners, and in particular, to a radiant heat exchange plate assembly. Background technique [0002] Most air conditioning systems in the prior art use air as the heat transfer medium. However, the all-air air-conditioning system has high energy consumption, poor human comfort, and is not conducive to the removal of pollutants in the indoor air. Therefore, the radiant panel refrigeration technology came into being. However, the previous radiant panel refrigeration technology cannot solve the problem of condensation on the panel surface when it is applied in high-heat and high-humidity areas in my country. [0003] In the current solution, since the heat transfer fins and the heat exchange coil are not in contact with the metal radiant plate, there are only radiation and convection heat transfer processes between the heat transfer fins, the heat exchange coil and the metal radiant plate. Although...
