Abstract

The utility model relates to a solar air warming machine which is composed of a heat collecting box, a fanner, a radiator and a delivery conduit. The fanner which is installed in a room is connected with the heat collecting box by a cold air pipe, and the hot air outlet of the heat collecting box is connected with the radiator by a hot air pip. Cold air in a room is fed into the heat collecting box by the fanner to be changed to be hot air current and to be returned to the room to form a forced circulation system. The solar air warming machine has reasonable design and structure, low cost and convenient installation and use, and the solar air warming machine can cause indoor temperature to achieve 10 to 15 DEG C when outdoor temperature is-20DEG C. The utility model is especially suitable for rural houses, plastic greenhouses and areas with fuel shortage. The utility model can cancel or supplement the existing auxiliary heat sources.

Description

Solar warm air blowing machine

It is the solar heating air device of thermal source with solar energy that the utility model relates to a kind of.

Town and country heating at present is many does thermal source with coal, wet goods, not only expends the energy, and pollutes indoor and outdoor surroundings.Existing passive solar house mostly adopts directly is benefited and heating system that the thermal-arrest wall combines, have at thermal-arrest wall or heat insulation window hollow sandwich fill insulant material, adopt this method construction trouble, cost height, particularly old housing reform is made more difficult.

The purpose of this utility model is a kind of solar heating air device of design, and this device is applicable to dwelling house, office and classroom, particularly grange, classroom, hot house etc., can cancel or additional original auxiliary thermal source.

The utility model is to be thermal source with solar energy, makes indoor cold airflow be transformed into thermal current by heat-collecting box, send into by blower fan indoor, thereby constitute a forced circulation system.Concrete structure and connected mode are: be contained in indoor blower fan and be connected by the cold air inlet of cool air hose with the heat-collecting box that can be shined upon, the hot-blast outlet of heat-collecting box is connected with indoor radiator by warm-air pipe.

Heat-collecting box is the critical piece of this device, be to make casing by base plate and heat-barrier material, heat-barrier material surface coverage on the base plate heat absorbing coating, it above the coating transparent material, transparent material can be plastic sheeting or simple glass, sunlight fully is transmitted on the heat absorbing coating, a seal cavity that air communication is crossed is arranged between coating and the transparent material.Heat-collecting box can be one, also can be a plurality of, and what can determine according to heating surface area quantity, is parallel connection between the heat-collecting box, and tilts to place on metope, roof or the vacant lot at a certain angle, to obtain more heat.

Radiator is a tubular radiator, and the radiating tube surface has louvre, so that thermal air current is to indoor.When not based on heating, and so that to use hot water be main, radiator can be changed into double pipe heat exchanger, interior pipe is connected with warm-air pipe, is communicated with cold water pipe between outer tube and interior pipe, and outer tube-surface is surrounded by insulation material.

The utility model is a thermal source with the sun, is heating agent with the air, and project organization is reasonable, and is easy to be easy-to-use, in my area, is 2m with every heat-collecting box ²Meter can obtain about 710,000 kilocalories heat in the heating phase.15m ²Dwelling house is adorned 2 heat-collecting box indoor temperatures on average can reach 10-15 ℃ corresponding to outdoor-20 ℃ the time, be specially adapted to the area of grange, classroom, hot house and lack of fuel.

Doing one below by accompanying drawing in conjunction with the specific embodiment of the present utility model describes in detail.

Fig. 1 is the overall schematic of utility model.

Fig. 2 is the heat-collecting box schematic diagram.

Fig. 3 is along the cut-away view of A-A direction among Fig. 2.

Fig. 4 is the radiator schematic diagram.

Referring to Fig. 1, this steam air heater is made of heat-collecting box, radiator, blower fan and conveyance conduit, blower fan (3) connects heat-collecting box (5) by cool air hose (4) through cold air inlet (14), blower fan (3) is installed in indoor (1) ceiling position usually, its effect is to make indoor cold air enter the heat-collecting box heating, hot-air in the return chamber exchanges with cold air again, generally adopts 150Pa, and flow is 500m ³The axial flow blower of/h just can satisfy classroom heating needs.The hot-blast outlet (15) of heat-collecting box (5) by warm-air pipe (2) be installed in indoor radiator (6) and be connected, make indoor cold air be transported to heat-collecting box and be transformed into hot-air and send back to indoor again by blower fan.

See Fig. 2, Fig. 3, heat-collecting box is the casing of being made by base plate (12) and heat-barrier material (10), heat-barrier material can be selected rigid polyurethane foams for use, Foam Plastic Surface is carried out the heat absorbing coating (11) that is covered with such as blacking layer or black stone cotton paper class, and the transparent material above the coating (8) is selected plastic sheeting for use, as polyethylene, polyvinyl chloride etc., thickness is 0.25-0.3mm, preferably adopt double-layer films, the spacing of double-layer films is about 60mm, to guarantee the ventilation temperature.It between heat absorbing coating (11) and the innermost layer plastic foil seal cavity (16), be provided with truncated cone shape diffusing opening (9) in this space and at the cool air hose of bottom half 14 places that enter the mouth, cold airflow is evenly entered in the casing, in the space at casing top, be provided with hot-blast outlet (15).The quantity of heat-collecting box can be definite according to heating area, generally speaking, and 15m ²Dwelling house and 56m ²The classroom, select 2 and 7 for use, can make indoor temperature improve 10-15 ℃.Heat-collecting box can be made different sizes and shape according to the shape of house south elevation, can be placed between the metope that can fully draw sunlight, roof, door and window, window and on the ground, casing is with respect to placing preferably tilt angle about 60 ° of plane, so that obtain abundant heat.

See Fig. 4, the warm-air pipe (2) of (1) is connected with radiator (6) through threeway (7) in the inlet chamber, and radiator is a tubular radiator, and the radiating tube surface has louvre (13) equably, radiating tube can the parallel placement in about 400mm place apart from ground, and it is indoor that hot-air is dispersed in equably.
