Problems solved by technology

[0003] But from the point of view of energy saving, when the general water heater is in low light or no light, the solar collector itself will produce heat loss, and after there is no light, the water temperature in the solar collector will drop significantly, and when the water is heated again, The starting point of the heating water temperature of the solar collector needs to be when the sunlight intensity reaches the standard, and the temperature of the stored water in the collector is used as the heating starting point. Therefore, the power consumption of electric supplementary heating in winter is greatly increased, which increases the production cost and operation of the solar water heater. cost, and the water in the solar collector will also cause the solar collector to freeze and crack, which greatly reduces the service life of the solar water heater

Description

(1) Technical field [0001] The invention relates to a solar water heater, in particular to a high-efficiency heat collection device for a split solar water heater suitable for use in regions with short daytime, insufficient light, freezing in winter and alpine regions. (2) Background technology [0002] The split type solar water heater is a kind of high-efficiency and energy-saving solar water heater. The biggest difference between the split type solar water heater and the traditional integrated solar water heater is that the water tank of the solar water heater is installed indoors instead of being installed outdoors together with the solar collector, which effectively avoids the The water tank is prone to freezing outdoors. [0003] But from the point of view of energy saving, when the general water heater is under low light or no light, the solar collector itself will generate heat loss, and after no light, the water temperature in the solar collector will drop significa...
