The invention provides an efficient flat plate type solar evaporation panel. An integral type metal solar heat collection panel which is used for collecting solar radiation energy is utilized. One side of the integral type metal solar heat collection panel is of a flat plate structure, and refrigerant snake-shaped semicircular flowing channels are arranged on the other side of the integral type metal solar heat collection panel. An inlet and more than two outlets are formed in the refrigerant snake-shaped semicircular flowing channels. L-shaped flanging edges are formed in the periphery of the integral type metal solar heat collection panel towards the surface with the refrigerant snake-shaped semicircular flowing channels so that the strength of deformation resistance of the integral type metal solar heat collection panel can be improved. Refrigerants in the refrigerant snake-shaped semicircular flowing channels serve as heat exchange media, gas-phase flow and liquid-phase flow are formed, narrow refrigerant pipelines with the pipe diameter ranging from 1mm to 3mm are adopted by the flowing channels of the efficient flat plate type solar evaporation panel, the number of the flowing channels and the total circulation area are gradually increased, and therefore the efficient flat plate type solar evaporation panel can adapt to the feature of the gas-phase flow and the liquid-phase flow of the refrigerants in the solar evaporation panel and the characteristic that refrigerant steam completely exists in the final outlets.

A kind of high-efficiency flat type solar evaporation plate, for collecting the metallic monolith solar energy heating of solar radiant energy
Plate, it is simultaneously slab construction, another side is the snakelike semi-circular runner of cold-producing medium；Which is provided with an import and two or more goes out
Mouthful；The snakelike semi-circular pipes' analysis of the circumferential cold-producing medium of the four of metallic monolith solar heat-collection plate form L-shaped flanging, to improve metal
The intensity of the monoblock type solar heat-collection plate resistance to deformation of itself；Cold-producing medium is used as heat exchange matchmaker in the snakelike semi-circular runner of cold-producing medium
Be situated between, biphase gas and liquid flow, the runner caliber that high-efficiency solar evaporation plate is adopted for 1～3mm narrow and small refrigerant line, and runner number
Amount and total circulation area gradually increase, the characteristics of to adapt to solar energy evaporation plate inner refrigerant biphase gas and liquid flow and final outlet
Locate the characteristic of all refrigerant vapours.
Described inlet and outlet in the form of insertion weldering, draw by welding copper pipe, and inlet and outlet
Fairlead is picked out by lower end, it is ensured that high-efficiency flat type solar evaporation plate front is plane.
Beneficial effects of the present invention：
1. a kind of high-efficiency flat type solar evaporation plate is in solar energy heat pump system, cold-producing medium Natural Circulation or mechanical cycles
Use as refrigerant evaporator in system, for the phase infantile feverish perspiration for collecting solar radiant energy and pass through bottom flow passage inner refrigerant
Heat absorption is sent out, in transferring heat to condenser, so as to the High Efficiency Thermal for realizing solar energy is utilized.High-efficiency flat type solar evaporation plate
Bottom runner be refrigerant flow path, internal circulation is refrigerant air-liquid mixed flow.Under normal operating conditions, refrigerant liquid
Body is flowed into from an import, and solar irradiation is mapped in plate face, and solar radiant energy causes plate face temperature to raise, and liquid refrigerant is along stream
Road gradually absorbs heat evaporation, gradually becomes refrigerant vapour, finally after cold-producing medium flows completely through evaporation plate, is then all evaporated to system
Refrigerant vapor, flows out from outlet.The high-efficiency flat type solar evaporation plate reduces the interlayer thermal resistance of traditional solar thermal collector,
Have the advantages that heat conduction efficiency is high, it is adaptable to which direct expanding solar heating pump system, refrigerated medium pump drive forced circulation system, system
Refrigerant natural circulation system, and processing technology is simple, and reliability is high, light and beautiful.
2. a kind of high-efficiency flat type solar evaporation plate, is first and last snakelike half the characteristics of its circuit design has uniqueness
Round type runner, but entrance is two pipes system, is to split into two runners by an import, is progressively divided then along refrigerant flow direction
Flow for many control, multiple outlets are finally flowed to again and are flowed out.It is all conflux and shunting at by round and smooth pipeline transition, rather than straight tube
The form of road bifurcated, to prevent from increasing flow field resistance, causes cold-producing medium to dam.The purpose of this kind of type design scheme is to enter
Mouthful place is refrigerant liquid, middle for refrigerant air-liquid mixed flow, and exit is refrigerant vapour, cold-producing medium be along runner gradually
Evaporation expansion, volume gradually increases, and refrigerant vapour pressure also gradually rises, therefore, in order to ensure stablizing for flow field
Property, reduce flow field resistance, damage of the gas lock to solar energy evaporation plate and the impact to systematic function are prevented, pipeline form should
It is designed to an import, the form of two or more outlets.
3. a kind of high-efficiency flat type solar evaporation plate, the outdoor frosting powder of lower surface spray black thereon, one be for
Raising solar radiant energy absorptivity, two be that evaporation plate is played a protective role.
