Novel multi-layer heat radiation structure of heater

Abstract

The invention relates to a novel multi-layer heat radiation structure of a heater. The novel multi-layer heat radiation structure comprises a heat radiation rack assembly and heating tube assemblies. The heating tube assemblies are installed inside the heat radiation rack assembly in parallel. The heat radiation rack assembly contains sheet metal flat plates, aluminium pipes, and radiating fins; the radiating fins are distributed at the middle parts of the aluminium pipes at equal intervals along the axis directions of the aluminium pipes; the aluminium pipes are distributed horizontally side by side along the rear side length directions of the radiating fins; and the rear parts of the radiating fins are connected with the outer surfaces of the aluminium pipes. The left ends of the aluminium pipes are connected by one sheet metal flat plate and the right ends of the aluminium pipes are connected by one sheet metal flat plate. The heating tube assemblies are respectively installed in the aluminium pipes in a sleeving mode. According to the invention, the novel multi-layer heat radiation structure has advantages of reasonable structural design, low production and manufacturing costs, and convenient installation and usage and the like. Heat radiation hole expanding at two directions is realized to meet space requirements of the air conditioner and the warmer; the flexibility and adaptability are high; and defects existing in the traditional unidirectional heat radiation hole expanding way can be overcome.

Description

technical field [0001] The invention relates to the technical field of heater heat dissipation, in particular to a novel multilayer heat dissipation structure of a heater. Background technique [0002] Heaters are commonly used in daily life, such as heaters for air conditioners. Metal PTC rapid heaters have been developed rapidly in many fields since they were born as new heaters at the beginning of this century. Their rapid heating, environmental protection and safety characteristics are especially suitable for use as auxiliary heating for air conditioners and heaters. The traditional metal PTC fast heater and the air conditioner design match mainly through its heating power, surface load, and installation conditions, while the air conditioner’s heating power and installation conditions are initially determined, and the heater expands the cooling holes in a single direction The more cooling holes, the lower the surface load. By adjusting the number of holes, it can meet t...

Problems solved by technology

[0003] With the continuous development of air conditioners, their size and space are becoming more and more miniaturized, and the space left for metal PTC fast heaters is getting narrower and narrower. Traditional metal PTC fast heaters expand the number of cooling holes in one direction and adjust the surface load. Space requirements for air conditioners and heaters
