Abstract
The utility model discloses a plate core of a solar thermal collector of heat exchange type with double mediums, comprising hollow heat conducting profile. At least one heat conducting medium channel is arranged in the hollow heat conducting profile; a first heat conducting fin fixedly connected with the heat conducting medium channel is arranged with intervals in the hollow heat conducting profile; heat storage and heat transfer medium is sealed in the hollow heat conducting profile, so that heat conducting medium in the heat conducting medium channel is heated and outputs heat energy in an enclosed space of the heat conducting medium channel in the hollow heat conducting profile; the heat conducting medium may not be contacted with a transparent cover plate on the flat plate solar thermal collector, so that heat energy loss is greatly reduced; on one hand, the heat storage and heat transfer medium in the hollow heat conducting profile exchanges heat with the heat conducting medium in the heat conducting medium channel; and on the other hand, the first heat fin in the hollow heat conducting profile, a second heat fin on the inner wall of the heat conducting medium channel, and a third heat fin on the outer wall of the heat conducting medium channel substantially accelerate the heat energy conduction and increase the thermal conducting efficiency.
Description
Technical field
The utility model relates to a kind of solar thermal collector, more particularly, relates to a kind of two medium plate core for heat transfer solar heat-collecting that are used for solar thermal 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, heat-conducting medium 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 heat-conducting medium 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, two medium plate core for heat transfer solar heat-collecting 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 pair of medium plate core for heat transfer solar heat-collecting is provided, comprise hollow heat conduction section bar, be coated with solar selectively absorbing coating on the upper surface of this hollow heat conduction section bar, at least be provided with a heat-conducting medium passage in the described hollow heat conduction section bar, be arranged at intervals with first heat transmission fin of fixedlying connected in the hollow heat conduction section bar, be sealed with heat accumulation and heat transfer medium in the hollow heat conduction section bar with the heat-conducting medium passage.
The beneficial effect of described in the utility model pair of medium plate core for heat transfer solar heat-collecting is: by constructing a hollow heat conduction section bar, be coated with solar selectively absorbing coating on the upper surface of this hollow heat conduction section bar, at least be provided with a heat-conducting medium passage in the described hollow heat conduction section bar, be arranged at intervals with in the hollow heat conduction section bar and fixedly connected first heat transmission fin with the heat-conducting medium passage, be sealed with heat accumulation and heat transfer medium in the hollow heat conduction section bar.Thereby make output heat energy in heating back in the confined space of the heat-conducting medium passage of heat-conducting medium in hollow heat conduction section bar in the heat-conducting medium passage, heat-conducting 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 heat accumulation in the hollow heat conduction section bar and the gas in heat transfer medium and the heat-conducting medium passage carry out heat exchange on the one hand, first heat transmission fin in the hollow heat conduction section bar on the other hand, second heat transmission fin on the heat-conducting medium vias inner walls, the 3rd heat transmission fin on the heat-conducting medium channel outer wall has been accelerated the conduction of heat energy greatly, has improved heat conduction efficiency widely.
Below in conjunction with drawings and Examples described in the utility model pair of medium plate core for heat transfer solar heat-collecting is described further.
