Improved flat-plate compact directly freeze-proof solar water heater

Abstract

The invention relates to an improved flat-plate compact directly freeze-proof solar water heater, belonging to the field of solar water heater. The solar water heater is characterized in that same heat collectors of the solar water heater are symmetrically arranged below a support frame, wherein the exposed upper circulation connecting openings of the upper collecting pipes of the heat collectors and the exposed lower circulation connecting openings arranged at the upper part of the lower collecting and connecting pipes are arranged on the upper end face of the heat collector, heat-insulating material is coated on the lower collecting and connecting pipes arranged inside the heat collectors, and protective covers are arranged outside the heat-insulating material; and a hot water storage tank of the solar water heater is arranged above the support frame, the lower part of the hot water storage tank is provided with a cool water inlet, a hot water outlet, two upper circulation connecting openings and two lower circulation connecting openings which are symmetrically arranged, the hot water storage tank is internally provided with a conduction pipe and a inlet water diffuser, wherein the two upper circulation connecting openings the hot water outlet which are arranged at the lower part of the hot water storage tank are connected with each other and extend inside the hot water storage tank to the upper part of the same, the cool water inlet is connected with the inlet water diffuser which is arranged at the lower part of the hot water storage tank, the hot water storage tank of the solar water heater is correspondingly connected with the circulating water channels of the heat collectors by circulating pipe connecting parts.

Description

Technical field: [0001] The invention relates to an improved flat compact direct antifreeze solar water heater, which belongs to the field of solar water heaters. Background technique: [0002] The 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 the 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 the flat compact antifreeze solar water heater does not need special mai...

[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
