Abstract

The invention discloses a thin-tube type solar water heater. A heat absorbing core of the water heater consists of a cold water partition board, a hot water partition board, a bottom board, inner thin tubes and outer thin tubes. Selective-absorption coatings are plated on outer surfaces of the outer thin tubes and the cold water partition board. The outer thin tubes are protruded on the surface of a flat plate to form a stereoscopic capillary heat absorbing surface, accordingly, when the irradiation angle of the sun is changed, sunlight angles of surfaces of a part of the outer thin tubes are 90 degrees, and the heat absorbing area is increased equivalently. In addition, the outer thin tubes contact with cold water more sufficiently, and heat absorbing speed is increased.

Description

Tubule formula solar water heater
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to a kind of tubule formula solar water heater, this water heater heat exchanger core is made of base plate, cold water dividing plate, three blocks of massive plates of hot water dividing plate and inner tubule, two kinds of tubules of outer tubule, and three flat plate separation become two cavitys, and are connected by two kinds of tubules.
Two, background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and dull and stereotyped water heater has appearred comprising in solar water heater, and the plate type solar water heater is opened up markets rapidly with its longer service life and easy installation method.But existing flat-plate solar heat collector exists programming rate slow, and is subjected to the shortcoming of firing angle influence on solar day.The present invention has increased endotherm area, and has reduced the influence of insolation angle for heat absorption capacity by adopting the method for tubule tube-surface plating coating for selective absorption.
At present existing a plurality of patents about the plate type solar water heater, but by adopting the method for crooked copper pipe surface plating coating for selective absorption, increased endotherm area, and reduced insolation angle and find as yet to apply for a patent for the water heater of the influence of heat absorption capacity.Below list several existing relevant patents:
Patent " one pressure-bearing heat pipe flat plate solar water heater " (application number: 201010622329.3) propose a kind of water heater, its heat absorption is welded by heat pipe and the aluminium sheet or the copper coin that are coated with heat absorbing coating, the condensation segment of heat pipe is positioned at the heat collector outside and inserts water tank, directly carry out heat exchange with the water in the water tank, have the collecting efficiency height, heat absorption is fast, and is withstand voltage, freeze proof, characteristics such as the strong and long service life of anti-impact force.。
(application number: 201020608214.4) propose a kind of solar water heater, it is that flat plate collector is installed in the incubator both sides to patent " two-sided flat plate solar water heater ", has increased collector area, has improved collecting efficiency.
Three, summary of the invention
The present invention proposes a kind of tubule formula solar water heater.This water heater is made of water inlet, delivery port, insulation shell, heat exchanger core and transparent cover plate.Wherein heat exchanger core is made of base plate, cold water dividing plate, hot water dividing plate and inner tubule and outer tubule.Cold water dividing plate sunny slope and outer tubule outer surface are coated with coating for selective absorption.Inner tubule one end and hot-water cavity UNICOM, the other end is positioned at outer tubule inside.Outer tubule is enclosed within outside the inner tubule, and is gapped between the two, and outer tubule and cold water cavity UNICOM.Being distributed on the heat exchanger core surface of inside and outside tubule even compact, the material of cold water dividing plate and outer tubule all is the high materials of thermal conductivity such as copper or aluminium, hot water dividing plate and inner tubule material are the low material of thermal conductivity.Inside and outside tubule must be perpendicular to cold water dividing plate and hot water dividing plate.Because the tubule rostrum is for planar surface, form three-dimensional hair-like heat-absorbent surface, so sun irradiation angle is when changing, always some bend pipe surface angle at sunshine is 90 degree, is equivalent to increase endotherm area.And outer tubule pipe and cold water full contact, improved heat absorption speed.Water inlet is square on the upper side in water heater back central authorities, and delivery port is square on the lower side in water heater back central authorities.Hot-water cavity is clipped in the middle of insulation shell and the cold water cavity, is made of base plate and hot water dividing plate.
Four, description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is this schematic representation of apparatus.
Fig. 2 is the A-A sectional view of this device.
Fig. 3 is B part enlarged drawing.
Fig. 4 is C part enlarged drawing.
The position of marking is respectively among the figure: 1, water inlet; 2, heat exchanger core; 3, delivery port; 4, insulation shell; 5, transparent cover plate; 6, base plate; 7, hot-water cavity; 8, hot water dividing plate; 9, cold water cavity; 10, cold water dividing plate; 11, inner tubule; 12, outer tubule.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
The external attemperater of water heater of the present invention and water pump.Cold water enters cold water cavity 9 from water inlet 1, and cold water dividing plate 10 and outer tubule 12 outer surfaces are coated with coating for selective absorption, and luminous energy is converted into heat energy, by transmission of heat by contact heating cold water.Water after the heating enters hot-water cavity 7 from inner tubule 11, enters attemperater by delivery port 3.By the circulation, water constantly is heated, reach assigned temperature after, be stored in the attemperater.
