Problems solved by technology

[0004] However, most of the current split solar water heaters are ordinary gravity heat pipe split solar water heaters, which use multiple indirect heat exchanges to heat the water in the water storage tank, which increases the heat transfer resistance of the system and lowers its thermal efficiency. There is a safety hazard of overheating in the collector part
In addition, the carrying limit of ordinary gravity heat pipes makes the heat transfer distance of ordinary gravity heat pipe split solar water heaters limited, and it is difficult to achieve real long-distance indirect heat exchange, so that the current split solar water heaters usually have a certain installation distance limit

Embodiment Construction

[0029] Such as figure 1 , 2 As shown, a split type solar water heater of the present invention includes a solar heat collection part 1 and a water storage tank 3, and also includes a loop gravity heat pipe 2, and one end of the loop gravity heat pipe 2 is assembled on the solar heat collection part 1 The other end is assembled in the water storage tank 3 . The electric auxiliary heating device 4 is an optional equipment for the solar water heater.

[0030] The solar heat collecting part 1 is an important device that is placed outdoors to collect solar energy, and then converts the solar energy into thermal energy. Therefore, the solar heat collecting part 1 can be a common heat pipe type vacuum tube solar heat collector or a heat pipe type flat plate solar heat collector or the like. Specifically, as figure 2 The solar heat collection part 1 shown in the figure adopts a heat pipe type vacuum tube solar heat collector, including a vacuum heat collection tube 11, a common h...

Abstract

The invention discloses a split-type solar water heater. The split-type solar water heater comprises a solar heat collection part and a water storage tank, and further comprises a loop gravity heat pipe, wherein one end of the loop gravity heat pipe is assembled in the solar heat collection part; and the other end of the loop gravity heat pipe is assembled in the water storage tank. The split-type solar water heater is high in heat transfer efficiency, flexible to arrange, and high in safety performance due to no over-temperature hidden trouble of the solar heat collection part.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a split solar water heater. Background technique [0002] Since the beginning of the 21st century, due to the increasing attention to energy and environmental issues, it has become an urgent problem to find an alternative energy that is abundant in reserves, clean and can be put into practical use on a large scale. Among them, the abundant, widely distributed, clean and pollution-free solar energy is undoubtedly one of the most competitive options. The average solar radiation intensity on the earth's orbit is 1369W / m 2 , the total solar energy obtained by the earth can reach 173,000TW, and the global energy consumption is less than one ten-thousandth of the solar energy obtained by the earth. The development of solar energy has broad prospects, and solar water heaters are the most mature and commercialized technology in the application of low temperature areas in the field of ...
