Abstract
The utility model discloses a negative pressure type flat-plate solar heat collector. A heat absorbing plate of the flat-plate solar heat collector consists of an upper metal sheet and a lower metal sheet which are adhered together, wherein strip-shaped sink marks are pressed on at least one metal sheet; the strip-shaped sink marks are mutually communicated to form runners; during operation, a water circulating pump pumps heat transfer fluid (such as water) from the runners into a heat insulation water tank, so that negative pressure is formed in the runners of the heat absorbing plate; then water is absorbed from the water tank by a pipeline, thus forming negative pressure circulation; and the negative pressure circulation can not form positive pressure onto the upper metal sheet and the lower metal sheet which can not be caused to open, thus being capable of greatly lowering the pressure bearing requirement for the heat absorbing plate and achieving the purposes of simplifying the manufacturing technology and reducing the cost.
Description
Technical field
The utility model relates to a kind of solar energy heat utilization device, is specifically related to a kind of flat-plate solar collector.
Background technology
At present, solar thermal collector mainly contains vacuum tube solar heating element and flat-plate solar collector, wherein flat-plate solar collector more attractive in appearance and can better with architecture-integral.But shortcoming is that its metal absorber plate manufacture difficulty is bigger, and cost is higher! So it is universal like that in China at present not as vacuum tube solar heating element.
Summary of the invention
The purpose of this utility model is the problems referred to above at flat-plate solar collector, a kind of suction type flat-plate solar collector is provided, change traditional flat-plate solar collector into negative pressure operation (promptly manage internal pressure and be lower than atmospheric pressure) at operation under positive pressure (promptly manage internal pressure and be higher than atmospheric pressure), bearing requirements to absorber plate can reduce significantly like this, reach simplified manufacturing technique, the purpose that reduces cost.
For achieving the above object, the technical solution of the utility model is as follows: a kind of suction type flat-plate solar collector, comprise absorber plate, transparent cover plate, heat-insulation layer, water circulating pump and attemperater, the absorber plate delivery port links to each other with attemperater by water circulating pump, and water inlet directly links to each other with attemperater.Described absorber plate is made of two sheet metals that fit together up and down, wherein has the indenture that is forced out strip on the piece of metal sheet at least, the indenture formation runner that is interconnected, water circulating pump is with the heat transport fluid in the absorber plate runner (as water) pump in attemperater during operation, make and form negative pressure in the absorber plate runner and in attemperater, absorb water by pipeline, so just formed the negative pressure circulation, for guaranteeing the negative pressure in the absorber plate runner, the installation site of attemperater can not be higher than absorber plate, and have relief valve on the attemperater, to guarantee that attemperater can not form high pressure the absorber plate runner is produced normal pressure.If in attemperater and the less occasion of absorber plate difference in height, when also placing roof with storied building or attemperater such as three layers, then can directly relief valve be changed into steam vent and directly be communicated with, have steam vent on the attemperater, better low pressure in the guard box with atmosphere.
The beneficial effects of the utility model are, change traditional flat-plate solar collector into the negative pressure operation at operation under positive pressure, and the bearing requirements to absorber plate can reduce significantly like this, reaches simplified manufacturing technique, the purpose that reduces cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the structural representation of utility model.
1. transparent cover plates among the figure are 2. gone up sheet metal, 3. descend sheet metal, 4. heat-insulation layer, 5. delivery port, 6. attemperater, 7. relief valve, 8. water circulating pump, 9. water inlet.
The specific embodiment
In the drawings, between transparent cover plate (1) and the heat-insulation layer (4) is absorber plate, absorber plate is by last sheet metal (2) and following sheet metal (3) formation that fits together, be pressed with the strip indenture that is evenly distributed and is interconnected on the last sheet metal (2), after fitting, last sheet metal (2) and following sheet metal (3) just formed the heat transport fluid passage in the uniform absorber plate like this, make heat transport fluid with water here, the heat transport fluid passage is provided with a delivery port (5) and a water inlet (9) at least, delivery port (5) links to each other with attemperater (6) by water circulating pump (8), water inlet (9) directly links to each other with attemperater (6), has relief valve (7) on the attemperater (6).
When sunlight is arranged, start water circulating pump (8), absorb water from delivery port (5), toward attemperater (6) internal pump water, make the interior heat transport fluid passage of absorber plate form negative pressure, absorb water in attemperater (6) by water inlet (9), thereby the heat-carrying water that forms negative pressure circulates.The heat-carrying water circulation of this negative pressure can not make it distending to last sheet metal (2) and following sheet metal (3) the formation normal pressure that constitutes absorber plate, if owing to other reason, raise gradually such as operation back attemperater (6) temperature and to make air expanded by heating in the case, when pressure raises, relief valve (7) is opened exhaust automatically, guarantees to make absorber plate can not arrive malleation and destroys.So only need to carrying out the flanging pressing around the absorber plate or simple adhering and sealing gets final product.Need not welding and come pressure-bearing, so just simplified production technology, reduce manufacturing cost with thicker material.
Claims (4)
1. a suction type flat-plate solar collector comprises absorber plate, transparent cover plate, heat-insulation layer, water circulating pump and attemperater, it is characterized in that: the absorber plate delivery port links to each other with attemperater by water circulating pump, and water inlet directly links to each other with attemperater.
2. according to claims 1 described a kind of suction type flat-plate solar collector, it is characterized in that absorber plate is made of two sheet metals that fit together up and down, wherein has at least to be forced out the strip indenture that is interconnected on the piece of metal sheet.
3. according to claims 1 described a kind of suction type flat-plate solar collector, it is characterized in that being equipped with on the attemperater relief valve.
4. according to claims 1 described a kind of suction type flat-plate solar collector, it is characterized in that having on the attemperater steam vent.
