Embodiment Construction

[0014] figure 1 A vapor-liquid cycle solar water heater shown without a gas collection tank is composed of a hot water storage tank 1, a heat collector 2, a heat exchanger 3, an exhaust device 4, a heat resistance structure 5, and a thermostatic valve 6. The water tank is provided with a cold water inlet 7 and a hot water outlet 8. The heat collector adopts a flat plate heat collector, the exhaust device adopts a one-way exhaust valve, the heat transfer medium is 35% ethanol, the closing temperature of the thermostatic valve is less than 75 degrees, and the vapor-liquid circulation solar water heater is installed according to the heat collection cycle effect requirements A certain amount of heat transfer medium is injected, and a suitable expansion space is left in the heat collection and circulation system. The heat collector is radiated by the sun. Since the expansion space is filled with air, the heat collection circulation system is in a state of normal pressure. When the...

Abstract

The invention discloses a vapor-liquid circulating solar water heater which is composed of a heat storage water tank, a heat collector and a heat exchanger. A heat collecting circulating system is a vacuum negative pressure system. The vapor-liquid circulating solar water heater is characterized in that a circulating outlet of the heat collector is connected with a low-position connector of the heat exchanger, and a circulating inlet of the heat collector is connected with a high-position connector of the heat exchanger; and the system is provided with an exhaust device which is connected to the top of the heat collecting circulating system, a thermostatic valve is arranged between the exhaust device connector position of a lower circulating pipe and the heat exchanger, and an upper circulating pipe is provided with a heat resistance structure. The heat collecting circulating system is the vacuum negative pressure system, vapor-liquid mixed circulating is achieved, greater circulatingpower is brought to the heat collecting circulating system through bubbles, the heat collecting efficiency is high, layout of the heat storage water tank and the heat collector is facilitated, and thevapor-liquid circulating solar water heater can be better combined with a building.

Description

technical field [0001] The invention relates to a natural circulation flat solar water heater, in particular to a natural circulation solar water heater whose heat collection circulation system is a vacuum negative pressure system. Background technique [0002] Solar water heaters are energy-saving and environmentally friendly, but they are not as safe and comfortable as traditional water heaters. They are difficult to integrate with buildings, have poor stability, poor durability, and difficult maintenance. Contents of the invention [0003] The object of the present invention is to provide a solar water heater with simple structure, low cost, high user comfort, high heat collection efficiency, easy integration with buildings, stable and durable performance, and reduced maintenance. [0004] A vapor-liquid circulation solar water heater of the present invention is composed of a hot water storage tank, a heat collector, and a heat exchanger. The heat collection circulation...
