Problems solved by technology
[0002] Flat-panel household solar water heater is a durable and high-efficiency solar water heater, but when the ambient temperature drops below freezing point, the water in the collector of ordinary flat-panel water heater will freeze and expand, causing the water heater to be damaged by freezing
The existing patented technology "flat compact antifreeze solar water heater" applies the principle that the water in the tubular container will freeze in sequence under low temperature conditions according to the relative position, distance from the heat source, pipe diameter, and heat dissipation and heat preservation conditions. The principle is simple, durable, safe and reliable, the cost of antifreeze is low, and it is a flat compact antifreeze solar water heater that does not require special maintenance. However, the above patented technology has technical difficulties in the manufacture and installation of products with large collector areas. , the function of the product components is not perfect
