Solar energy heat exchange device with function of energy storage

Abstract

The invention belongs to the technical field of solar energy water heaters, and particularly relates to a solar energy heat exchange device with a function of energy storage. The solar energy heat exchange device comprises a water storage tank, a heat exchange mechanism which is arranged in the water storage tank and a heating mechanism which is connected with the water storage tank and can conduct heat conduct on heat water media in the water storage tank, and a water inlet pipe and a water outlet pipe of the heat exchange mechanism are arranged on the tank wall of the water storage tank; the water storage tank is provided with one or more spoiler baffles which are fixed on the tank wall and provided with convection holes, and the spoiler baffles divide the water storage tank into multiple areas with different temperatures in an up and down mode; an inlet and an outlet of the media of the heating mechanism are formed in the bottom of the water storage tank. According to the solar energy heat exchange device with the function of the energy storage, the heat energy of the water in the solar energy water tank can be stored and fully utilized. The solar energy heat exchange device with the function of the energy storage can be suitable for integrative installation and split-type installation of the solar energy water heaters; efficient energy extraction, energy conservation and safety are achieved.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to a solar heat exchange device with energy storage function. Background technique [0002] At present, the use of solar energy is to use the water in the water tank after being heated by solar tubes. When the hot water in the water tank cannot be used up at one time, the heat energy of the hot water generated will change with the day and night or the weather. A large amount is lost due to the change. and during use, [0003] Not only because the water in the solar water tank is generally used up in a day or two, but more than ten days, so that only a small part of the heat energy in the water heated by the solar energy in the water tank during the day is utilized, and most of the heat energy will be used due to When day and night come, it is lost through the tank, especially through the solar tube; and it goes round and round, causing the water in the sola...

Problems solved by technology

[0004] Because the water in the water tank has a phenomenon of high water temperature in the upper part and lower water temperature in the lower part (hot water will rush to the high place), when the water is released, not only the cold water in the downpipe must be released, but also the water tank near the outlet pipe must be drained. The water at the bottom also needs to be drained, so that the water with higher water temperature in the upper part of the water tank can be released, which not only causes waste of water, but more importantly, the accumulated solar energy is lost because it cannot be fully utilized; and

[0005] When the temperature of the water medium heated by solar energy is lower than the average temperature of the water medium in the water tank, the high and low temperature stratified water medium in the water tank will no longer absorb heat, which not only causes inconvenience in use, but more importantly limits the use of Use of solar energy

[0006] The utility model patent of Chinese Patent No. 200620072491.9 discloses a solar heat exchanger, which can make the heat energy of the water in the solar water tank be utilized through heat exchange; Stratified, there is also the defect that the thermal energy of solar heating cannot be preserved and fully utilized
