Abstract

The utility model belongs to a heat collecting plate for a solar water heater, which can replace a roof insulating plate. The utility model is characterized in that an included angle is formed between the heat absorbing fin of the existing flat plate type heat collecting plate and the soleplate of the existing flat plate type heat collecting plate, and an elevation angle and a rake angle are formed between the soleplate and a horizontal plane. The utility model can effectively absorb the light and heat of the sun and can overcome the defects that the existing heat collecting plate has a single function and various models, the heat collecting plates which are arranged on a roof are irregular for badly influencing view, etc. In addition, at the time of installation, the utility model can avoid that because the original laid heat insulating plates need disassembling, human and material resources are wasted.

Description

A kind of solar heat-collection plate that replaces roof insulating slab

The utility model relates to a kind of apparatus for heating water by solar energy member, specifically, is a kind of solar heat-collection plate that replaces roof insulating slab.

Along with promoting the use of of solar water heater, the roof in many places all progressively is that panoramic apparatus for heating water by solar energy is occupied.Be to improve solar energy collecting efficient, solar heat-collection plate is installed and is not taked the horizontal positioned mode usually, and takes the orientation perpendicular to the sunray radiation, and promptly monoblock thermal-arrest plate is 30 °～45 degree inclined-plane more and lays on the roof.Like this, because windage increases, the wind sky is easily blown to turn over, and leads to a disaster.So need carry out consolidation process when installing.In addition, because the particular requirement of thermal cycle aspect, heat-preserving container need be higher than thermal-arrest plate hight end certain altitude.For guaranteeing normal water supply, the pond, roof also need further be increased.So it is uneven just to form city roof solar hot water apparatus, the pond is too high, and thermal-arrest plate and thermal insulation board repeat to interlock and lay the phenomenon that roof a slice is in disorder.In addition, because former some thermal insulation boards that lay in roof also need be removed, caused meaningless waste.

The purpose of this utility model is in order to overcome the above-mentioned deficiency of prior art, to adopt change heat absorption fin welding and assembling angle mode to make a kind of solar heat-collection plate that replaces roof insulating slab.

The purpose of this utility model can be realized by following scheme: a kind of solar heat-collection plate that replaces roof insulating slab, comprise thermal-arrest board mount, heat absorption fin, and it is characterized in that absorbing heat is an angle β between fin (4) and the base plate (8); Between base plate (8) and the horizontal plane angle of elevation alpha is arranged; Delivery port collecting pipe (15) one sides are than the low inclination angle [theta] of water inlet collecting pipe (9) one sides.The size of angle β should change with the infield latitude is different, preferably makes the heat absorption fin (4) can be perpendicular to the sunlight incident direction in time of the year when autumn changes into winter, and angle of elevation alpha can be selected 8 °～12 °, and inclination angle [theta] can be selected 2 °～4 °.

Compared with prior art, but the utility model dual-use material, unified planning design when capital construction, but large tracts of land lay, can be all or most of replacement roof insulating slab, save the thermal insulation of roof construction investment in a large number; Simultaneously can make the roofing layout clean and tidy, help improving the urban construction style and features, and thermal-arrest plate windage reduces, both can save the installation flat cost, can effectively avoid contingency to take place again; Moreover because heat insulation layer is arranged at thermal-arrest plate bottom, and it is equipped with certain gradient, is beneficial to its underpart cross-ventilation, so effect of heat insulation is better than common thermal insulation board.Adopt the utility model that water tank and thermal-arrest plate hight difference are suitably increased, pond, roof height is suitably reduced.Like this, can weaken circulation heat radiation of solar water heater on the one hand, the hot water thermal insulating time is prolonged; On the other hand, reduce the pond height, both can save capital expenditure, also be beneficial to anti-anti-earthquake.

Accompanying drawing 1 is the utility model oblique view and Figure of abstract;

Accompanying drawing 2 is Figure 1A-A face cutaway views;

Accompanying drawing 3 is the utility model scheme of installations.

In the accompanying drawing, 1 is heat-preserving container, and 2 is the bucket support, and 3 is the hot-water circulation pipe, 4 are the heat absorption fin, and 5 is the thermal-arrest plate, and 6 is the thermal-arrest board mount, and 7 is glass, 8 is base plate, and 9 are the water inlet collecting pipe, and 10 is framework, and 11 is plug, 12 is finned tube, and 13 are water inlet collecting pipe four-way, and 14 are the threeway of water outlet collecting pipe, and 15 are the water outlet collecting pipe, 16 is pond, roof feed pipe, and 17 is cool water circulating pipe, and 18 for supplying user's hot-water line, and α is the thermal-arrest plate elevation angle, β is the heat absorption fin elevation angle, and θ is thermal-arrest plate inclination angle, and PW is a blowoff valve.

The utility model is described in further detail with embodiment with reference to the accompanying drawings below:

In accompanying drawing 1, make thermal-arrest plate (5) by conventional method, the fin (4) that will absorb heat by with the have angle fixed-site of β of base plate (8), finned tube (12) is welded respectively with water inlet collecting pipe (9) and water outlet collecting pipe (15) fix as shown in Figure 2.According to thermal-arrest plate infield difference, as cloud, expensive, Guangdong and Guangxi Provinces are regional, when being welded in finned tube (12) on the Inlet and outlet water collecting pipe, heat absorption fin (4) may be selected to be 23 °-26 ° with the angle β of base plate (8).By shown in Figure 3, two blocks of thermal-arrest plates are connected in parallel by water inlet collecting pipe four-way (13) and water outlet collecting pipe threeway (14) then; Thermal-arrest board mount (6) should be made and form angle of elevation alpha and inclination angle 0 when the thermal-arrest plate is laid; Angle of elevation alpha should be met south.Again routinely mounting process connect pond, roof feed pipe (16) and and heat-preserving container (1) between hot and cold water circulation pipe (17) and (3) get final product.When replacing roof insulating slab with this thermal-arrest plate, can unified planning when capital construction, with the two ends parallel connection of thermal-arrest plate, neatly be arranged in roofing in a manner described, both can heat-preserving container be set by the family, also can take the central heating mode, large-scale shared insulation pond is set.
