Abstract
The utility model discloses a folding-plate-type high-temperature air radiation heat collector. The folding-plate-type high-temperature air radiation heat collector is characterized by comprising a heat collection plate, wherein the heat collection plate is formed in the mode that a flat plate is bent to form a hollow flat plate, continuous V-shaped oblique ribs are arranged in the middle of the hollow flat plate, and air holes are formed in the heat collection plate. Two reinforcing strips are arranged on each of two sides of the heat collection plate. A radiation absorption material layer is coated on the surface, facing the high-temperature radiation side, of the heat collection plate. According to the folding-plate-type high-temperature air radiation heat collector, under the condition that a radiation receiving area is given, a larger heat exchange area with air can be provided, and the heat exchange area can be adjusted as needed to enable the temperature of the air to be more approximate to the temperature of the heat collector. When flowing air passes through the heat collector, more heat can be carried away compared with an ordinary heat collector and used as a heat source of a heat energy collector. Due to the fact that a stable triangular structure interface is formed, the folding-plate-type high-temperature air radiation heat collector has high compression-resistant performance and is firmer and more durable. The folding-plate-type high-temperature air radiation heat collector can be used not only as a close-range radiant heat air receiver of a high temperature body but also as an air collector of solar energy and other radiant heat under additional heat preservation conditions.
Description
Technical field
The utility model relates to a kind of hyperthermia radiation air heat energy gathering system, relates more particularly to a kind of folded plate type high temperature air radiation heat collector.
Background technology
Existing air collector is generally for collection solar radiation warm, the position of the sun is far, environment temperature is lower, radiation loss is very large, therefore the back side of heat collector is incubated with insulation material, positive glass heat-insulating with the transmissive radiation, and insulation material and reinforcement material thereof have just consisted of the framework of heat collector, therefore collecting plate does not need to bear very strong extraneous power, so often adopt the trough plate type structure; And the hyperthermia radiation air collector is used for collecting the radiant heat of in-plant high temp objects, therefore environment temperature is higher, radiation loss is little, and heat radiation is in the air of thermal-arrest, therefore, the general back side does not need insulation material, and the front does not need glass, if but heat collector itself does not have good resistance to compression stability under loading, need to do the framework of stablizing its structure to heat collector again.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of folded plate type high temperature air radiation heat collector, has adopted resistance to compression stability under loading hipped plate construction preferably, does not need to make separately framework it is reinforced.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of folded plate type high temperature air radiation heat collector is characterized in that: comprise collecting plate, described collecting plate is the hollow slab of continuous V-arrangement diagonal rib in the middle of being formed by flat plate buckling, and described collecting plate is provided with air-vent.
The angle beta of described dull and stereotyped bending is 10 °-80 °.
Described air-vent evenly divides on collecting plate, and on unit collecting plate area, the shared ratio of air-vent area is 2%-10%.
Described collecting plate both sides respectively are provided with two reinforcing strip.
Described reinforcing strip adopts steel bar to make.
Described collecting plate is towards the surface of hyperthermia radiation side coating radiation-absorbing material layer.
Described collecting plate is made by silver, copper or aluminium sheet.
The utility model with respect to the beneficial effect of prior art is:
The utility model can provide larger and can adjust as required with heat exchange area air and heat exchange area in the situation that radiation receiving surface is long-pending given, makes the temperature of air closer to the temperature of heat collector; When this heat collector of moving air process, can take away than the more heat of general air collector, as the thermal source of heat energy collecting device; Owing to having formed stable triangular structure interface, better anti-compression property is arranged, make it firm and durable more.The utility model can be used as the closely radiant heat air receiver of high-temperature body, also can be used as the photothermal air collectors such as solar energy.

The specific embodiment
Shown in Fig. 1-2, a kind of folded plate type high temperature air radiation heat collector is characterized in that: comprise collecting plate, described collecting plate is the hollow slab of continuous V-arrangement diagonal rib in the middle of being formed by flat plate buckling, and described collecting plate is provided with air-vent.The angle beta of described dull and stereotyped bending is 10 °-80 °.The interface of group triangular structures more than the both sides of V-arrangement diagonal rib and collecting plate form, crushing resistance is good, firm and durable; The bending of collecting plate can provide larger and heat-transfer surface air, and Heat-collecting effect is good.The angle beta of dull and stereotyped bending is decided according to the requirement of heat output, needs the amount of heat transfer larger, and the angle beta of bending is larger, and under same collector area, the area of heat transfer plate is just larger like this; Otherwise, need the amount of heat transfer less, the angle beta of bending is less.
Described air-vent evenly divides on collecting plate, air-vent is in order to allow air that thermal-arrest uses flow into from the heat collector surface, it to be appeared from the back side, and air-vent diameter minimum is 1mm, is 10mm to the maximum, can exempt from dust and stop up air-vent, air-flow is evenly distributed on collecting plate.The shared ratio of air-vent area on unit collecting plate face is long-pending changes with unit are thermal-arrest air mass flow, is generally 2% to 10%.
Described collecting plate both sides respectively are provided with two reinforcing strip.Described reinforcing strip adopts steel bar to make and uses or other high temperature resistant, high-intensity metals.
Described collecting plate is towards the surface of hyperthermia radiation side coating radiation-absorbing material layer, with enhanced rad heat absorption effect.Described collecting plate is made by silver, copper or aluminium sheet, to increase heat-transfer effect.
