Problems solved by technology

But it also has obvious defects: poor reliability, difficult maintenance, if one tube is damaged, the whole system will not be able to operate; the inner tube is prone to scale and difficult to remove; cannot operate under pressure; large heat capacity, large heat loss; frost cracks Hidden danger
[0014] However, there are still insurmountable technical defects in this method. First, the channels of the flat-plate solar collector units are connected in series or in parallel, and the liquid working fluid needs to be heated by the solar energy collected by the heat absorber to form steam. It is generated in the multi-elbow rotary pipeline, so that the steam is not easy to generate and the pressure of the steam is not high, and the steam is not easy to enter the circulation and then promote the work of the entire circulation system
Secondly, since the working medium must be distributed in multiple heat absorbers to absorb solar energy, and enter the circulation system to heat the water in the water tank, this requires more liquid working medium and it is difficult to determine the perfusion amount of the li

Example Embodiment

[0088] Example one

[0089] Combine figure 1 The heat energy transmission method of the heat pipe solar water heating system of the present invention is described in detail. The thermal energy transmission method of the present invention specifically includes two processes:

[0090] The first process is the process of collecting solar energy by the heat pipe type heat collecting unit 10 and converting the solar energy into heat energy; this process is a heat collecting process, mainly through the heat pipe type solar heat collecting unit 10 to collect solar energy and convert it into heat energy. With the extremely high heat collection efficiency of the heat pipe type solar heat collection unit 10, solar energy is collected and thermal energy conversion is completed inside the heat pipe. The heat energy is conducted to the heat energy transmission process through the heat exchange end 11 of the heat pipe type heat collecting unit 10.

[0091] The second process is a heat energy tra...

Example Embodiment

[0124] Example two

[0125] The solar water heating system of this embodiment is such as figure 2 As shown, the working principle and effect of thermal energy transmission in this embodiment are basically the same as those in the first embodiment.

[0126] Specifically, in an embodiment, the sealed cycle heat energy transmission system adopts a vacuum system, and the air pressure inside it is lower than atmospheric pressure, so that the heat exchange working medium 30 therein is easier to boil, even in northern areas with low temperatures in winter, or high altitude areas It can also be used normally. In the specific implementation process, a vacuuming device can be installed on the steam channel 60 or the working fluid return channel 70. After the tightness of the entire system is tested, the vacuuming operation is performed first, and then the vacuuming device is closed, and then the liquid injection The device injects the heat exchange working medium 30, and finally seals the ...

Example Embodiment

[0131] Example three

[0132] The solar water heating system of this embodiment is such as image 3 As shown, the working principle and effect of thermal energy transmission in this embodiment are basically the same as those in the first embodiment.

[0133] Such as image 3 As shown, the difference between this embodiment and the first embodiment is only that the secondary heat exchanger 50 and the water tank 40 have a horizontal coil structure. In this way, due to the existence of the coil structure, the contact area between the secondary heat exchanger 50 and the water tank 40, that is, the heat exchange area, increases, and the heat transfer efficiency in the water tank 40 is correspondingly improved.

[0134] In this embodiment, as image 3 As shown, the heat collection unit 10 may be arranged in a horizontal row, and the heat exchange end 11 of the heat collection unit 10 is connected to the heat collector 20 arranged vertically.

Abstract

The invention discloses a heat transmission method and a system for a heat-pipe-type solar hot water system, relating to a solar hot water system, in particular to a split type solar hot water system. The heat transmission method comprises the process of converting solar energy into heat by a heat-pipe-type heat collection unit, and a heat transmission process of transmitting the heat into a water tank by a heat transmitting system and heating low-temperature water in the water tank, wherein the heat transmission process is that a continuous liquid-gas-liquid phase change is carried out in a completely-sealed circulation system through a heat-exchange working medium in a heat collection device so as to realize transmission of heat collected and converted by the heat collection unit to a water tank. According to the heat transmission method and the system, heat can be effectively transmitted between a condensation end of the heat-pipe-type solar heat collection unit and a split type water tank, thus heat loss is reduced, long-distance heat transmission of a livelihood hot water tank and a solar heat collection device is realized without the needing of external auxiliary energy, and the requirement of a modern high-rise building is met.
