Description

A kind of tiling type solar water heater
Technical field
The utility model relates to a kind of solar water heater, more particularly say, be meant mode that a kind of employing circulates the liquid forced heat-exchanging carry out exchange heat, can make things convenient for large tracts of land gather solar heat, be applicable to the tiling type solar water heater that roof, body of wall are installed.
Background technology
Solar water heater is made up of complete glass vacuum sun thermal-collecting tube, attemperater, bearing support three big parts.Its core set thermal element is an all-glass vacuum thermal-collecting tube, and it is formed for concentrically ringed high borosilicate ultrahard glass tube by two.Through full-automatic full-computerized filming equipment and with advanced in the world " the only membrane technology of magnetron sputtering ", in a vacuum outer wall of inner tube is plated multilayer gradual change aluminium-nitrogen-aluminized coating or stainless steel aluminium nitride, can stand 400 ℃ high temperature, this coating is to the selective absorption of sunshine, its absorptance 〉=0.92, emission is than≤0.09 (80 ℃).Vacuum heat collection pipe selectivity absorption sunshine is converted into heat energy with luminous energy constantly heats the water in the vacuum tube.Because " thermal siphon " effect, promptly the proportion of cold water is bigger, and the proportion of hot water is less.Thereby the hot water in the vacuum tube enters water tank naturally constantly toward come-up.Water in water tank constantly sinks naturally, enters vacuum tube.Go round and begin again, the water in solar water heater's attemperater also just has been heated.
Direct insertion all-glass vacuum thermal-collecting tube solar water heater, be high-absorbility and the low-launch-rate that utilizes vacuum heat collection pipe to have, convert the solar radiation that absorbs to heat energy, utilize cold water than great, the characteristics that hot water proportion is little form cold water from top to bottom, hot water Natural Circulation from bottom to top in vacuum tube, the temperature of whole water is progressively raise, reach uniform temperature.But the pipe inner storing water amount of existing vacuum heat collection pipe is excessive, and heat conduction toggle speed is slow, easily causes heat waste.Generally, water capacity is 3L in the diameter 58mm, the pipe of the vacuum heat collection pipe of long 1.8m, and the solar water heater water tank capacity of one 30 arm is 250L, and then the water in the vacuum heat collection pipe will reach 90L, account for 26% of Total Water.Because of the defective of existing structure, store this part water in vacuum heat collection pipe and entrained heat thereof after the intensification, not only can not be used effectively, play the effect of heat radiation on the contrary.
The defective that existing direct insertion all-glass vacuum thermal-collecting tube solar water heater roughly exists is as follows:
