Problems solved by technology

However, in Japanese Patent Laid-Open No. 2004-176966, since there is a space layer (gap) between the special metal film and the heat collector, the heat generated by the special metal film cannot be efficiently conducted from the special metal film to the heat collector. Body, therefore, there is a problem that the heat collecting structure cannot meet the above requirements

[0037] exist figure 1 In the above, the upper side of the paper indicates the upper side (one side in the first direction, one side in the thickness direction), the lower side in the paper indicates the lower side (the other side in the first direction, and the other side in the thickness direction), and the left side in the paper indicates the left side. side (the side of the second direction orthogonal to the first direction), the right side of the paper indicates the right side (the other side of the second direction), and the near side of the paper indicates the front side (orthogonal to the first direction and the second direction). One side of the third direction), and the depth side of the paper indicates the rear side (the other side of the third direction). Specifically, the direction is figure 1 The direction arrow of . figure 2 Subsequent figures start with figure 1 direction as the basis. In addition, in figure 2 In the figure, in order to clearly show the r...

no. 2 Embodiment approach

[0081] In the second embodiment, the same reference numerals are assigned to the same components and steps as those in the first embodiment, and detailed description thereof will be omitted.

[0082] Such as Figure 5 As shown, the solar heat collection multilayer sheet 21 has a substrate sheet 10 , a solar radiation absorbing layer 3 and a low emissivity-low solar reflectance layer 4 .

[0083] The substrate sheet 10 is used to support the solar radiation absorbing layer 3 and the low emissivity-low solar reflectance layer 4, and the solar radiation absorbing layer 3 and the low emissivity-low solar reflectance layer 4 are arranged on the heat collecting plate 2 (imaginary line) support sheet. The plan view shape of the base material sheet 10 is formed to be the same as the plan view shape of the solar heat collecting multilayer sheet 21 . In addition, the external shape of the base material sheet 10 is not limited to the said shape, It can be formed in an appropriate shape...

Embodiment 1

[0107] Make solar collectors

[0108]Prepare an aluminum plate (thickness 0.5mm) as a heat collecting plate, then apply a black body paint on the upper surface of the heat collecting plate to form a sunlight absorbing layer (thickness 30 μm), then, on the upper surface of the sunlight absorbing layer, use An ITO film (thickness 250nm) was formed as a low emissivity-low solar reflectance layer by sputtering. Thus, a solar thermal collector including a heat collecting plate, a solar absorbing layer and a low emissivity-low solar reflectance layer (refer to figure 1 ).

Abstract

A solar heat collector includes a heat collecting board, a solar radiation absorbing layer provided at one surface in a thickness direction of the heat collecting board, and a low emissivity and low solar reflectance layer provided at one surface in the thickness direction of the solar radiation absorbing layer.

Description

technical field [0001] The present invention relates to a solar thermal collector, a solar thermal collector multilayer sheet and a solar heater, in particular to a solar thermal collector, a solar thermal collector multilayer sheet and a solar heating system with a solar thermal collector and a solar thermal collector multilayer sheet device. Background technique [0002] Conventionally, it is known that solar heaters such as solar water heaters have heat collectors that are heated by absorbing sunlight and then heat water (heat medium) inside the heat collectors to obtain hot water. [0003] In the heat collector (heat collection structure), it is necessary to prevent the heat absorbed by the heat collector from escaping to the outside, that is, to reduce heat radiation. [0004] For example, a heat collection structure of a solar energy collection device is proposed, which includes: a heat absorber; For example, refer to JP-A-06-201197.). In the heat collecting structu...
