Description

Through type exterior focusing inner fin heat exchange solar energy heat collector

Technical field

The utility model relates to a kind of solar thermal collector, more particularly, relates to a kind of through type exterior focusing inner fin heat exchange solar energy heat collector.

Background technology

Traditional flat-plate solar collector mainly is by heat-absorbing plate core, be coated on the solar selectively absorbing coating on the heat-absorbing plate core upper surface, comb with the heat-absorbing plate core welding, transparent cover plate, insulating and shell constitute, air-flow after the heat-absorbing plate core heating contacts with the transparent cover plate (glass plate) on the flat-plate solar collector, can not on heat-absorbing plate core, form airtight air-flow heat tunnel, cause heat energy to run off in a large number, heat loss is big, and the heat transfer efficiency of heat-absorbing plate core is low, and comb is welded on outside the heat-absorbing plate core in addition, heat mainly is to conduct by the solder joint between comb and the heat-absorbing plate core, and heat conduction efficiency is greatly limited.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides a kind of and can significantly reduce that heat energy runs off, heat loss is little, can effectively increase the area of heat exchange, the through type exterior focusing inner fin heat exchange solar energy heat collector that heat conduction efficiency is high.

For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of through type exterior focusing inner fin heat exchange solar energy heat collector is provided, comprise the reflect focalization device, be arranged on described reflect focalization device top and supply the reflection ray of reflect focalization device and the heat insulation light penetrating object of hollow that direct projection light sees through, be equiped with solar energy heat absorption pipe in the heat insulation light penetrating object of this hollow, light is absorbed by solar energy heat absorption pipe through reflection of reflect focalization device and the direct heat insulation light penetrating object of hollow that sees through, and solar energy heat absorption pipe will enter heat accumulation and the heat transfer medium heating in it.

The beneficial effect of through type exterior focusing inner fin heat exchange solar energy heat collector described in the utility model is: by constructing a reflect focalization device, the heat insulation light penetrating object of hollow that sees through for the reflection ray and the direct projection light of reflect focalization device on described reflect focalization device top, be equiped with solar energy heat absorption pipe in the heat insulation light penetrating object of this hollow, light is absorbed by solar energy heat absorption pipe through reflection of reflect focalization device and the direct heat insulation light penetrating object of hollow that sees through, solar energy heat absorption pipe will enter heat accumulation and the heat transfer medium heating in it, thereby make heat accumulation and the heat transfer medium confined space heating back output heat energy in solar energy heat absorption pipe, heat accumulation and heat transfer medium can not contact with the transparent cover plate (glass plate) on the flat-plate solar collector, significantly reducing heat energy runs off, heat loss is little, and solar energy heat absorption pipe is to entering heat accumulation and the heat transfer medium heating in it on the one hand, be provided with some heat transmission fins on the other hand in the solar energy heat absorption pipe, form heat accumulation and passage for heat transfer medium between adjacent two heat transmission fins, effectively increased the area of heat exchange, improved heat conduction efficiency widely, the taper fluid dividing cover at described hollow tube two ends is evenly distributed heat accumulation and heat transfer medium, helps further improving heat conduction efficiency.
