Abstract
The invention discloses a snakelike runner flat-plate solar collector. The solar collector takes a flat rectangular box body as a heat-absorbing body, the inner cavity of the heat-absorbing body is divided into snakelike runners, and the outer surface exposed to the sun is plated with a selective absorbing coating, thus a heat conducting liquid can rapidly absorb heat and heating speed and heating efficiency are improved.
Description
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to a kind of solar thermal collector, its absorber is the cuboid casing that inner flow passage is snakelike distribution, and the outer surface that casing faces south is coated with coating for selective absorption.
Two, background technology
At solar energy heat utilization field; The multiple matured product of vacuum tube collector and flat plate collector has appearred comprising in heat collectors for solar water heater; Flat-plate solar heat collector is opened up markets rapidly with its longer service life and easy installation method.But, still can not adapt to the northern cold cold weather because bigger, hot water programming rate of heat loss and amplitude are poorer slightly than vacuum tube collector.
At present existing a plurality of patents about flat-plate solar heat collector, but absorber directly is designed to the cuboid casing, and inner flow passage is the patent discovery as yet of snakelike layout.Below list several existing related patent U.S. Patent No.:
(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates constitute to patent " efficient freeze proof plate type solar water heater ", is full of water in the gap between two metallic plates, and the absorber upper surface is coated with coating for selective absorption.Because the water yield in the absorber gap is fewer, when water freezing expanded, Volume Changes was within the regime of elastic deformation of metallic plate, and can guarantee can be not freezing.
Patent " the built-in many piecemeals assembled flat of circulation pipe type solar water heater " (application number: 200920253847.5) propose a kind of modular plate type solar water heater; This device is designed to the unit that module is with the heat collection body of water heater, is convenient to install and transportation.
Patent " a kind of wall hanging whole pressure-bearing flat plate solar water heater " (application number: 201020192486.0) propose a kind of solar water heater that thermal-arrest layer and storage tank are integrated, the loss of minimizing heat transmission course.
Three, summary of the invention
The present invention propose a kind of with the cuboid casing as the heat collector absorber, inner flow passage is snakelike layout, and absorber on the sunny side one side be coated with coating for selective absorption.Serpentine flow path flat-plate solar collector structure comprises: insulation shell, transparent cover plate, import, outlet, absorber, wherein absorber is made up of heat absorption body wall and serpentine flow path again.Insulation shell is selected the material of good heat preservation performance, firm, light weight for use.Absorber is processed into by metal sheet, and the absorber inner chamber is very flat, and the serpentine flow path internal diameter after the separation is smaller, makes fluid therein big endotherm area can be arranged.A side external surface on the sunny side of absorber is coated with coating for selective absorption.After the placement, the heat collector import below, the outlet up.
Four, description of drawings
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is the front section view of this device.
Fig. 2 is the A-A cross-sectional view of this device.
The position of marking is respectively among the figure: 1, insulation shell; 2, heat absorption body wall; 3, serpentine flow path; 4, import; 5, outlet; 6, transparent cover plate.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
The import of serpentine flow path flat-plate solar collector and the external condenser hot well liner of outlet.When sunny, the selective heat absorbing coating that heat absorption body wall 2 appearances are coated with is converted into heat energy with luminous energy, and heat absorption body wall 2 is heated up.Heat-conducting medium in the inner bag gets into the mobile heat absorption in serpentine flow path 3 longshore current roads through import 4 and heats up, and gets back to heat release the inner bag from exporting 5.
Claims (4)
1. serpentine flow path flat type solar heat collector, this device is made up of lagging casing (1), absorber, import (4), outlet (5), and wherein: absorber is made up of heat absorption body wall (2), serpentine flow path (3).
2. a kind of serpentine flow path flat type solar heat collector according to claim 1, it is characterized in that: absorber is processed by metal sheet, and inner chamber is flat, and the serpentine flow path that is separated into (3) internal diameter is little.
3. a kind of serpentine flow path flat type solar heat collector according to claim 1 is characterized in that: the outer surface that heat absorption body wall (2) faces south is coated with coating for selective absorption.
4. a kind of serpentine flow path flat type solar heat collector according to claim 1 is characterized in that: after the placement, heat collector import (4) below, the outlet (5) up.
