As a result, the utility model has the characteristics of good light transmission property, good heat preservation property, good heat taking property, convenient fabrication, simple and compact structure, light weight, low cost, convenient installation, convenient transportation, etc.

Description

Plastic film solar energy heat collector

The utility model relates to the plastic sheeting solar thermal collector that a kind of sunlight is adopted hot heat supply water, is specially adapted to family and utilizes sunlight to adopt the device of hot heat supply water.

Along with the increase of the mankind to energy needs, the utilization of solar energy more and more comes into one's own, and it is more and more to utilize solar energy to adopt hot hot-water supply especially.Its heat collector part of the solar energy water heater device that existing market is sold mostly makes heat-collecting box with metallic plate, the heat collector that also has is formed by connecting with many metallic conduits, and cover glass in the heat-collecting box tank surface, reach the transparent heat insulating purpose, though this water heater Heat-collecting effect is fine, but it is many to expend metal material, cost is higher, Heavy Weight, processing and fabricating difficulty, inconvenience is installed, can not the large tracts of land penetration and promotion uses.Another kind of simple water heating device directly is subjected to water tank solar radiation to adopt heat, and its light-receiving area is little, is not incubated, and result of use is undesirable, and above water heater installation and transportation are all inconvenient.

The purpose of this utility model is to avoid the not middle part in the above-mentioned background technology and provides a kind of Heat-collecting effect good, the plastic sheeting solar thermal collector that cost is extremely low, and the utility model can satisfy printing opacity simultaneously, be incubated, adopts hot property, also having structure tightly plays simply, in light weight, processing and fabricating is simple, and characteristics such as easy transportation and installation have practical application value.

The purpose of this utility model is achieved in that it is made up of plastic sheeting heat collector 1, plastic sheeting warmer 6.Plastic sheeting heat collector 1 is hot pressed into 1 to 300 standpipe 7 by good black plastic film 3 midfeathers of two-layer photo absorption performance, hot sealing becomes integral body, upper and lower side hot sealing to become collector pipe 8 around the two-layer black plastic film 3, collector pipe 8 and 1 to 300 standpipe 7 internal run-through, and the water inlet pipe and water outlet pipe 2 of inferior horn hot pressing on collector pipe 8 and the plastic sheeting heat collector 1 is communicated with; Be hot pressed into 1 to 5 layer of heat-insulation layer in plastic sheeting heat collector 1 levels outside with transparent plastic film 4 and constitute plastic sheeting warmer 6, transparent plastic film 4 intermediate heat of every layer of plastic sheeting warmer 6 are pressed into 1 to 200 air

thermal preservation chamber

5,6 hot pressing of plastic sheeting warmer are sleeved on plastic sheeting heat collector 1 outside, and plastic sheeting thermal-arrest 1 water inlet pipe and water outlet pipe 2 is connected with external storage tank.

The utility model is compared with background technology has following advantage:

1, the utility model all adopts plastic sheeting to make, and hot pressing, bonding or straight forming form, so processing and fabricating is simple, and suitable batch process is applied, and has printing opacity simultaneously, is incubated, adopts characteristics such as good in thermal property.

2, the utility model structure is tightly played simply, can adopt hot pressing or bonding way to make, thereby the production and sales cost is low, and is in light weight, flexible, is convenient to installation and transportation.

3, the utility model Heat-collecting effect is good, makes of plastic sheeting, and the big I of its volume is made arbitrarily, therefore can be made into the heat collector of multiple dimensions, satisfies the requirement of different user, can carry out large-area penetration and promotion.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the broken section structural representation of the utility model along the A-A line.

With reference to Fig. 1, Fig. 2, the utility model is made up of plastic sheeting heat collector 1, plastic sheeting warmer 6.Plastic sheeting heat collector 1 is hot pressed into 1 to 300 standpipe 7 by good black plastic film 3 midfeathers of two-layer photo absorption performance, be made into the laminar heat collector of comb form, embodiment standpipe 7 also can adopt bonding forming, two-layer black plastic film 3 also can be made of other colored plastic film, as long as just can with the good plastic sheeting of photo absorption performance, purpose is mainly used to improve the Heat-collecting effect of standpipe 7 water storages, the no specific (special) requirements of internal diameter size of hot pressing or bonding standpipe 7, but be difficult for excessive, the excessive effect of internal diameter is bad, the embodiment internal diameter size is 50 millimeters, the big or small embodiment of plastic sheeting heat collector 1 is made into 1 square metre of size, also can be made into the heat collector of other different size specifications, to satisfy the needs of different user.Sealing of hot pressing or bonding one-tenth is whole around the two-layer black plastic film 3, its upper and lower side hot sealing becomes collector pipe 8, collector pipe 8 and 1 to 300 standpipe 7 internal run-through, and the water inlet pipe and water outlet pipe 2 of inferior horn hot pressing on collector pipe 8 and the plastic sheeting heat collector 1 is communicated with, and water inlet pipe and water outlet pipe 2 is connected with external storage tank.

Be hot pressed into 1 to 5 layer of heat-insulation layer in plastic sheeting heat collector 1 levels outside with transparent plastic film 4 and constitute plastic sheeting warmer 6, transparent plastic 4 intermediate heat of every layer of plastic sheeting warmer 6 are pressed into 1 to 200 air thermal preservation chamber 5, embodiment adopts 3 layers of heat-insulation layer to be made with the colourless transparent plastic film, every layer of air thermal preservation chamber 5 that the heat-insulation layer intermediate heat is pressed into, its size does not have specific (special) requirements, but can not be too big or too little, too little too greatly heat insulation effect is all bad.Embodiment air thermal preservation chamber 5 internal diameters are made into 100 millimeters, be made into a plurality of moist closets, in air thermal preservation chamber 5, fill air during hot pressing, play function of heat insulation, 6 hot pressing of plastic sheeting warmer are sleeved on plastic sheeting heat collector 1 outside, and its contour structure size is decided with the physical dimension of plastic sheeting heat collector 1.

Can keep flat the utility model during use and be placed on the roof, also can be suspended on the wall on the sunny side, make 1 daylighting as far as possible of plastic sheeting heat collector.After piling water in the external water tank, also be full of water in the standpipe 7 of plastic sheeting heat collector 1, the collector pipe 8, standpipe 7 is under solar radiation, make the inside water heating, reach Heat-collecting effect, because the water proportion after the heating is little, can float, reach water in standpipe 7 and the external water tank purpose that circulates automatically, because therefore aeroseal in the air moist closet 5 in the plastic sheeting warmer 6 has good transparent heat insulating effect.
