Description

High energy efficiency solar plate heat collector and solar cold warm air conditioner
Technical field
The utility model relates to a kind of solar thermal collector, particularly a kind of flat type solar heat collector.The utility model also relates to the solar cold warm air conditioner that adopts above-mentioned flat type solar heat collector.In addition, the utility model has also related to the processing method of above-mentioned flat type solar heat collector.
Background technology
In utilizing the process of solar energy, key is that the radiant energy with the sun converts heat energy into.Because solar energy relatively disperses, must manage to put together it, this just needs to adopt solar thermal collector, is used for absorbing solar radiation and makes it to convert into heat energy and pass to thermal medium.
Solar thermal collector is the various key components of utilizing solar energy equipment.The most common solar thermal collector has plate and vacuum tube type.The solar cold heating air conditioner patent of the for example patent No. of vacuum tube type: ZL2005201402412 adopts uses the glass-vacuum tube heat collecting type.The flat heat collecting formula then for example number of patent application be 201110193234.9 disclosed flat-plate collectors.
Glass vacuum tube type heat collector advantage is that Heat-collecting effect is fast, and the heat transferring medium of use is in glass-vacuum tube, directly to circulate to carry out heat exchange, just says that also medium in the warm heat exchanger that weighs and the medium in the vacuum tube mix.If vacuum tube thermal-arrest mode winter temperature low excessively, the easy bursting by freezing of vacuum tube; And go up also explosion easily of water summer, after vacuum tube broke, the medium of water tank will all be revealed.
The flat type solar heat collector of usefulness and existing market is everlasting; Mostly be with copper coin one little or monoblock or aluminium sheet; Pitch-dark in the spraying of the one side of plate, at the another side copper pipe of burn-oning, the contact-making surface of copper pipe and plate face has only a very thin line face; Do frame with aluminium alloy then and simple glass seals, this product can be done the branch water heater body.
But, because the heat-absorbent surface of this product is with flat, owing to can not use too thick copper coin or aluminium sheet; Under solar energy, be exposed to the sun for a long time like this, the plate face can be out of shape, and the copper pipe that the plate facial disfigurement can cause and weld comes off; The solder side of itself is just very little; Heat-conducting area is too little, and the heat of heat-absorbent surface can not fully conduct to copper pipe, and thermal conversion rate is too poor.Compare with the electron tubes type heat collector, thermal conversion rate is too wide in the gap, surperficial simple glass, and environment temperature is crossed low or overheated, also breaks easily.After above situation occurring, cause solar airconditioning refrigeration, heating efficiency to descend, Energy Efficiency Ratio is lower, can not make equipment give full play of self effect.
The utility model content
The utility model technical problem to be solved provides the higher high energy efficiency solar plate heat collector of a kind of thermal efficiency; The solar cold warm air conditioner that the utility model also provides the processing method of above-mentioned solar plate heat collector and adopted above-mentioned solar plate heat collector.

A kind of high energy efficiency solar plate heat collector comprises face glass, frame and backboard, and said face glass, backboard and frame constitute enclosure space; Said backboard is provided with heat-insulation layer; Heat-insulation layer is provided with absorber plate, is provided with copper pipe between said absorber plate and the heat-insulation layer, and said absorber plate is one group of fin perpendicular to face glass and backboard; The two ends of said copper pipe are respectively import and outlet; The copper pipe of part interts on fin with endless form repeatedly between the export and import, and said face glass is surfacing, and there is the glass of water caltrop its inside.
Said fin is copper fin or aluminium fin.
The width of said fin is 3-5cm.
The surface of said fin is coated with fluorine carbon.
The utility model also relates to a kind of solar cold warm air conditioner that adopts above-mentioned high energy efficiency solar plate heat collector.Adopt the solar cold warm air conditioner of the high energy efficiency solar plate heat collector of the utility model, more meet environmental protection, energy-conservation requirement, can design, can reach 40%---70% than the common air-conditioning economize on electricity with a large amount of evidences with architecture-integral.Underload superelevation, low temperature running, use usual pressure pump or compressor can accomplish the T3 operating mode at the long-life.
The processing method of the high energy efficiency solar plate heat collector of the utility model may further comprise the steps:
1) adopts wide copper of one group of 3-5cm or aluminium fin in identical middle part punching, and stretch and keep certain flatness;
2) copper pipe is passed from the above-mentioned hole that dashes, keep certain distance between fin and the fin;
3) adopt the technology of producing condenser that copper pipe is expanded slightly, guarantee that fin is fixed on the copper pipe firmly, and guarantee that all fins all keep an angle of 90 degrees to stand on the copper pipe;
4) the copper pipe two ends in the fin are welded import and outlet respectively;
5) carry out fluorocarbon-sprayed to above-mentioned fin;
6) do frame with aluminium alloy then, with rigging-angle connector four jiaos are connected and fix, be separated by with foaming layer at the aluminium alloy periphery;
7) pave with steel plate in the aluminum alloy frame bottom surface, on steel plate, place heat-insulation layer again;
8) be fixed on maintenance sealing on the aluminum alloy frame to toughened glass panel with the silica gel sealing bar at last.
The utility model compared with prior art, fin surface uses the spraying of environment-friendly type fluorocarbon coating, has high temperature resistant, corrosion resistant performance, its life-span can reach 20 years.
Polylith fin (concrete quantity look in the size, face glass of heat collector spacing decides between water caltrop refraction angle and fin) combination; Compare with ordinary flat formula heat collector; Frame is measure-alike, but endotherm area is big, punching on the fin; Copper pipe is through in the fin hole, and heat exchange area has also increased greatly like this.Through experiment, thermal efficiency ordinary flat heat collector has on year-on-year basis improved 50%.
Compare this utility model with the vacuum tube thermal-arrest and be more suitable for being used for the separated type solar air-conditioner, because of present development of city, skyscraper is many; The whole solar airconditioning of electron tubes type not too is fit to skyscraper, and vacuum tube breaks easily, and this utility model is fit to use the demand with the heating or the cooling of family, enterprises and institutions with architecture-integral; Compare vacuum tube; The medium that uses preparation in copper pipe heat transferring medium, this utility model can be used under-15 ℃ of temperature, hot summer; Go up water suddenly, can be as the vacuum tube explosion yet.The utility model not only thermal efficiency has improved, and be suitable for and multiple environment under freeze or heat with any construction conditions under install and use.
