specific Embodiment approach 1

[0013] Specific implementation mode one: combine Figure 1 to Figure 13 Describe this embodiment, a heat transfer-enhanced low-resistance solar flat panel collector of this embodiment, which includes a heat absorber 1, a transparent cover plate 2, a frame 3, at least one spoiler 4, an insulating material 5 and a back plate 6, the heat absorber 1 includes multiple sets of circular tubes 1-1 and multiple heat absorbing plates 1-2, multiple sets of circular tubes 1-1 are arranged in parallel, and an absorber is passed between two adjacent sets of circular tubes 1-1 The heat plate 1-2 is connected; the thermal insulation material 5 is installed on the back plate 6, the heat absorber 1 is installed on the thermal insulation material 5, and at least one spoiler 4 is installed in each group of circular tubes 1-1, and the same group of circular tubes The direction of rotation of the two adjacent turbulence devices 4 in the tube 1-1 is opposite. On the transparent cover plate 2 and th...

specific Embodiment approach 2

[0016] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the upper end surface of the thermal insulation material 5 of this embodiment is provided with a plurality of arc-shaped grooves 5-1 at equal intervals. With such arrangement, it is convenient to embed multiple sets of circular tubes 1-1 into the arc-shaped grooves 5-1, and the heat-absorbing plate 1-2 can be placed between two connected arc-shaped grooves 5-1. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0017] Specific implementation mode three: combination Figure 1 to Figure 7 The present embodiment will be described. The chainring 7 of this embodiment is an annular chainring with notches. Such setting prevents its endothermic expansion from extruding the circular tube flow path. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The utility model relates to a heat-transfer-enhanced low-resistance solar flat panel heat collector, relating to a solar flat panel heat collector. The invention solves the problem that the heat absorbing body of the existing flat-plate solar heat collector cannot efficiently transmit solar energy to the working medium in the flow channel. Multiple groups of circular tubes of the present invention are arranged in parallel, and two adjacent groups of circular tubes are connected by a heat absorbing plate; the thermal insulation material is installed on the back plate, the heat absorbing body is mounted on the thermal insulation material, and at least One turbulence device, and the direction of rotation of two adjacent turbulence devices in the same group of circular tubes is opposite, the two sides of the thermal insulation material are higher than the upper surface of the heat absorber, the transparent cover is installed on the thermal insulation material, and the frame is installed on the The transparent cover plate and the back plate; the two toothed discs are arranged opposite to each other, and the middle part between the two toothed discs is connected by a plurality of torsion plates, and the circumferential direction of the two toothed discs is evenly distributed with a plurality of torsion plates whose rotation direction is opposite to that of the torsion plates. Stick to the wall. The invention is used for solar heat collection.

Description

technical field [0001] The invention relates to a solar flat panel heat collector, in particular to an enhanced heat transfer type low-resistance solar flat panel heat collector. Background technique [0002] In recent years, as the problem of environmental pollution has become increasingly serious, more and more scientific and technological workers have paid more and more attention to solar energy as a clean energy source. The flat plate solar collector is a basic component for converting solar energy into heat energy. It is mainly composed of a frame, a transparent cover, a heat absorber, an insulation material, a back plate and a seal. Cross-sectional metal runners for the passage of heat-conducting media. Flat-plate solar collectors have the advantages of simple structure, less maintenance and failure, convenient installation, and low cost. They have been widely used in many fields such as domestic water heating, building heating and air conditioning, refrigeration and ...
