Abstract
A dual channel waveform core board solar power air collector belongs to a solar power heat utilization device. The utility model provides a high efficiency low cost air collector, and is characterized in that a waveform heat collection chip divides a heat collection chamber into two heating channels in the direction of thickness. The heat collection chip and air flow can exchange water through both sides. By adopting the waveform heat collection chip, heat collection area is increased, and perturbance of air is enhanced. The rate of the length of the collector to the thickness ranges from 11 to 13. A draw-type air filtration dehumidizer is provided on an air inlet end face; a discharge fan is provided on an air outlet end face to force air into convection. Connecting pieces for modularized parallel assembly of the collector are fixed on both sides of a frame of the collector. In an experiment, under the air conditions of solar radiation of more than 900w/m<2>, and the ambient air temperature of 20 DEG C, two 3.6W DC fans are adopted for artificial draft; air temperature of the outlet of the collector is as high as 70 DEG C. The connecting pieces on both sides of the frame of the collector can provide conditions for the collector to be assembled in a line in parallel in the modularized way.
Description
Technical field
The utility model belongs to solar energy heat utilization device, relates to a kind of solar energy air heat collector.
Background technology
Flat air collector reception solar radiation area is big, and cost of manufacture is low, and installation and transportation are convenient, and thermal response is fast, extensively applies to fields such as building heating, agricultural product, agricultural byproducts, woods fruit product drying.But also there is the big shortcoming of area of dissipation, causes the heat collector outlet air temperature on the low side.Existing plate type solar air collector majority is all from reducing heat radiation, increases air adding in heat collector to improve aspect the hot path, to improve outlet temperature, perhaps increases the heat storage capacity of heat collector with heat accumulating.As the utility model of number of patent application 85200928, feature is to have an air return flow line, increases air and add hot path in heat collector.The utility model of number of patent application 88221059.9 (publication number 2042939U) and 93248208.2 (publication number 2193978Y) and for example, feature are the transparent honeycomb structure are installed between transparent cover plate and absorber, to reduce the heat loss of upper cover plate.The utility model of number of patent application 200510040068.3, it is characterized by between the absorber plate of traditional flat air collector and base plate and fill heat accumulating, utilize heat accumulating to absorb and the storage solar heat, to reduce the air collector thermal loss, improve the thermal efficiency, but it is bigger that these heat collector materials expend, and cost is higher.
Summary of the invention
A kind of solar energy air heat collector is made up of heat collector backboard, sunny slope air duct, opaco air duct, support, heat-insulation layer, glass, heat collection chip, air-filtering dehumidifier, press strip, connector and frame.The length of air collector and thickness proportion are directly connected to the thermal efficiency and the outlet temperature of air collector.Under the certain situation of heat collector length, heat collector thickness is big, air drag by heat collector is little, the heat collector outlet can obtain the air stream of big flow, though the thermal efficiency is high, but airflow temperature can be lower, if heat collector thickness is less, though the airflow temperature that obtains is higher, flow can reduce, and the thermal efficiency reduces.The utility model is from the length of heat collector and the proportionate relationship of thickness, propose a kind of efficient, low-cost, binary channels solar energy air heat collector that the flowed energy loss is little, can under the prerequisite that does not increase cost, improve the outlet hot air temperature of air collector.
The technical scheme that adopts:
A kind of solar energy air heat collector, it is characterized in that waveform heat collection chip (7) is separated into two air heat passages along thickness direction with heat collector cavity, wherein, sunny slope air duct (2) highly is 1.8～2.2 times of opaco air duct (3) height, the flowed energy loss of admission passage is little, be easy to do turbulent motion, accelerate the heat collector exchange heat; Heat collector air intake end face install can pull air-filtering dehumidifier (8), adopt the waveform heat collection chip, both can increase collector area, can make the air that enters heat collector produce disturbance again, make the abundant heat exchange of air and heat collection body.
Air collector length and thickness are than between 11-13.
Described heat collector frame (11) both sides are fixing for the connector (10) of heat collector with the modular parallel assembling.
The waveform heat collection chip can increase the heat exchange amount between air and the heat collection body, and the sunny slope gas channel is suitably greater than the opaco gas channel.Through the experiment, in solar radiation greater than 900w/m
2, under the meteorological condition that ambient air temperature is 20 ℃, adopting the DC fan forced draft of 2 3.6W, air collector outlet hot air temperature can reach 70 ℃.
