Abstract

Disclosed is a dehumidifying and anticorrosion heat-collecting plate core. A glass cover plate and a metal absorber plate in a flat-plate solar collector are peripherally supported by a seal support strip frame which is filled with drying agent. Two sides of the seal support strip frame are hermetically connected with the glass cover plate and the metal absorber plate through sealant. When the collector collects heat, air in an interlayer cavity expands, and the compressed air is discharged through an inflating exhaust nozzle. When the air in the collector shrinks due to cooling and generates negative pressure, pre-expansion form of the metal absorber plate is extended, bent and recessed, and the damage of negative pressure is relieved. The lingering problems that moist gas dews to reflect sunlight and corrodes an absorber coating and heat is lost since the unsealed collector brings away heat are solved. The dehumidifying and anticorrosion heat-collecting plate core has such advantages that the service life of the collector is prolonged and effective heat gain is increased.

Description

The heat-collecting plate core of dehumidifying anti-corrosion function

Technical field

The invention belongs to the heating equipment field, exactly is the heat-collecting plate core of dehumidifying anti-corrosion function.

Background technology

The flat-plate solar collector that existing market is sold all is packing less, heat collector when thermal-arrest the air in the heat collector because of volumetric expansion, by the external exhaust in slit, the air when not having sunlight in the heat collector easily is drawn into humid air in the heat collector because the cooling volume-diminished begins air-breathingly.Even when making heat collector, insulation material is dried, pass through the thermal-arrest exhaust of a period of time in the use, cool off air-breathing, the damp atmosphere that the outside is a large amount of sucks, make and gathered the globule that much condenses under the heat collector glass cover-plate, sunlight reflected to the outside, is gently then stoped sunlight to be injected the thermal efficiency is reduced, heavy then corrode heat absorbing coating, cause the heat absorbing coating permanent damage.In order to address this problem, there is the people when producing heat collector, consciously 1～2 hole respectively to be opened in heat collector lower end and upper end, allow natural convection air, when thermal-arrest, the high-temperature water band of gas in the heat collector is walked.But the another one problem occurred be: though the high-temperature water band of gas in the heat collector has been walked during thermal-arrest, solved the glass condensation trouble, but taken away a lot of heat energy simultaneously yet, caused the collecting efficiency of heat collector to reduce a lot, the problem of corrosion heat absorbing coating is not improved at all.

Summary of the invention

Task of the present invention provides a kind of heat-collecting plate core with dehumidifying anti-corrosion function, sealing between the plate put in order in glass cover-plate and the metal heat absorption of flat-plate solar collector all around, periphery carries out long-term hygroscopic desiccation with drier, both solved wet gas corrosion heat absorbing coating problem, the problem of a lot of heat energy has been taken away in perforate about having solved again, improve the hotly effective of solar thermal collector, prolonged service life.

In order to realize above-mentioned task, the dehumidify heat-collecting plate core of anti-corrosion function of the present invention, glass cover-plate and the whole plate of metal heat absorption of flat-plate solar collector are sealed with sealing support bar frame all around, and desiccant-filledly in four limits sealings support bar frame carry out long-term hygroscopic desiccation, to seal support bar frame two sides seals with fluid sealant and glass cover-plate, the whole plate of metal heat absorption, air expansion in the interlayer chamber during heat collector thermal-arrest is chewed the compressed gas discharge of expansion by the inflation exhaust.Air can produce negative pressure because of the cooling volume-diminished in heat collector, and the pre-intumescent of the whole plate of metal heat absorption is stretched, and the crooked indent of the whole plate of metal heat absorption is simultaneously alleviated negative pressure harm.

Characteristics of the present invention: solved for a long time that the wet gas dewfall flashes back the sunlight, wet gas corrosion heat absorbing coating is because the heat waste problem of heat energy is taken away in the heat collector blow-by.Prolong heat collector service life, improved effective advantages such as heat.
