Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] As shown in Figure 1, the combined solar heat collection and heat storage device includes a box body 1, the top of the box body is a light-facing glass cover plate 2, the middle part is a heat absorption layer 3, and the bottom is a heat storage layer 4; it is characterized in that: The heat-absorbing layer has an orifice heat-absorbing body 7, and the bottom of the heat-storing layer is gravel 5, and a water-filled black sealing pipe 6 is laid thereon.

[0014] The structure of the orifice absorber is shown in Figure 2. The size of the orifice absorber 7 is 2000mm×1000mm. The size of the holes 8 on the orifice absorber 7 is Φ20mm. The forks are arranged on the plate, and the area ratio of the holes 8 and the orifice heat absorbing body 7 is 30-40%.

[0015] As shown in FIG. 3 , the orifice plate heat absorber 7 is arranged in the middle of th...

Abstract

The solar heat collecting and accumulating apparatus includes one tank with one transparent glass cover in the top, one heat absorbing layer in the middle part and one heat accumulating layer in the bottom. It features the heat absorbing layer with perforated plate as heat absorbing body, and the heat accumulating layer with gravels in the bottom and water filling black sealed tubes laid on the gravels. The perforated plate as heat absorbing body has cross arranged holes accounting for 30-40 % of the surface area. The present invention has simple structure and capacity of supplying heat all day long in all weathers, and is suitable for solar energy generating, greenhouse, air conditioning and other fields.

Description

technical field [0001] The invention relates to a combination device of solar heat collection and heat storage. Background technique [0002] Solar heat collectors are generally transmitted from the sun's radiation to a heat absorber made of coated steel, aluminum or stainless steel sheets. Due to the absorption of solar radiation, the metal sheet is heated, and the heat is transferred to the water pipe below the sheet. The heated water or air is passed to the user or the heat storage system; this kind of solar collector can only collect solar energy during the day when the weather is fine, but it cannot work normally at night or in rainy days, and the heat collection effect is not ideal, and the application range is limited , Not suitable for solar thermal wind power generation, greenhouse, HVAC and other occasions. Contents of the invention [0003] The present invention proposes a combined solar heat collection and heat storage device, the purpose of which is to overco...
