Abstract

The invention provides a honeycomb cover which comprises a flat plate. Honeycomb through holes are arranged on the flat plate, the flat plate comprises a first surface and a second surface, and the through holes extend from the first surface to the second surface. Ratio of depth to hole diameter of the through holes is 1.5-6. The flat plate is provided with at least one fixed part. A flat-type far infrared radiation device with the honeycomb cover comprises a heater, a radiation flat plate, an insulating layer and the honeycomb cover. The heater is connected with the radiation flat plate. One face of the radiation flat plate is connected with the insulating layer, and the other face of the radiation flat plate is a radiation face. The honeycomb cover is arranged in front of the radiation face. The fixed part is connected with the radiation flat plate. By the aid of the honeycomb cover, convective heat loss of the flat-type far infrared radiation device in the air can be effectively restrained, and accordingly efficiency of the flat-type far infrared radiation device converting heat energy into far infrared radiation is improved.

Description

technical field [0001] The invention relates to the electrical field, in particular to a honeycomb cover and a flat-plate far-infrared radiation device provided with the honeycomb cover. Background technique [0002] The existing flat-plate far-infrared radiation device (such as an electric heater, etc.) is a flat plate with high far-infrared radiation rate. The side facing away from other heating targets such as people, houses or objects is pasted with an insulation layer, and the other side is a radiation surface. Expose to the air or cover with wire mesh (to prevent burns); use electric heating or other heating methods, when the temperature of the plate is higher than the ambient temperature, the radiation surface will radiate far-infrared light to heat the target. [0003] The working temperature of the flat infrared radiation device (electric heater) is between 40°C and 200°C. It has the advantages of uniform and comfortable heating, no fire hazard, and no dazzling red ...
