[0042] Example 3:

Embodiment 2

[0044] In the above-mentioned embodiments of the light energy heat collecting device of the present invention, as attached figure 2 As shown, the glass body 130 can be set as a glass plate compatible with the solar heat collecting tube 120, for example, a flat glass plate whose length and width are suitable for the solar heat collecting tube 120, or curved glass plate, whose shape is adapted to the solar heat collection tube 120; or, the glass body can also be set as a glass tube that is compatible with the solar heat collection tube 120, and the glass tube is coaxially sleeved on the solar heating On the tube 120 ; for example, a cylindrical glass tube whose diameter exceeds that of the solar heat collecting tube 120 , and another example, a prismatic glass tube whose shape is adapted to the solar heat collecting tube 120 .

Embodiment 3

[0046] Further, as attached figure 2 As shown, on the basis of the reflective layer 170, an insulating layer 180 is arranged on the back of the reflective layer 170. The insulating layer 180 can be made of a solid solid insulating material, or a solid insulating material with air holes. The configuration can prevent the heat of the light energy heat collecting device or the glass tube from dissipating outward.

[0047] Based on the above-mentioned light energy heat collecting device, the present invention proposes a method for preventing the light energy heat collecting device of a solar water heater from generating fog, which is used to prevent the inner surface of the glass on the light energy heat collecting device from generating fog, as shown in the attached Figure 6 shown, including the following steps:

[0048] Step S610, the solar photothermal layer 160 located in the solar heat collecting device absorbs solar energy to generate heat;

[0049] Step S620, the solar ...

Abstract

The invention discloses a method for eliminating mist on a light energy heat gathering device of a solar energy water heater, including a solar energy photoheating layer in the light energy heat gathering device for adsorbing the solar energy and generating heat. The solar energy photoheating layer transmits the heat on a glass body which has mist on an inner surface and heats the glass body. The glass body absorbs the heat generated by the solar energy pohotoheating layer. The mist one the inner surface of the glass is evaporated. Because the technical scheme that the solar energy photoheating layer is arranged on the glass body out of a solar energy collector tube is adopted, even if a thermal insulation layer is a gas insulating layer under a non-vacuum state, at the same time that the solar energy collector tube absorbs the solar energy and exchanges heat with liquid in the tube, the solar energy photoheating layer on the glass body can also absorb the solar energy and heat the glass body to lead the temperature to rise. The rising of the temperature also evaporates the mist condensed on the inner surface of the glass body.

Description

technical field [0001] The invention relates to the field of water heaters using solar energy to heat cold water. More specifically, the improvement relates to a light energy heat collecting device of a solar water heater and a method for eliminating fog on it. Background technique [0002] As people's awareness of energy conservation and environmental protection continues to increase, energy-saving and environmentally friendly products are gradually recognized and accepted by people, and solar water heaters are one of them; A solar collector tube and a plurality of corresponding vacuum tubes coaxially arranged on its outer side are used to prevent mist generation, that is to say, in order to prevent fog from being generated on the inner surface of the vacuum tube and reduce the effect of absorbing solar energy by the solar thermal collector tube, The space between the outer wall of the solar heat collection tube and the inner wall of the vacuum tube adopts a technical mean...
