The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides a heat collector, which can be applied to a solar device, such as a solar water heater. As shown in fig. 1 and 2, the heat collector includes a frame 1, a heat absorbing body 3, and a grill 4. The frame 1 is used as a framework of the heat collector and plays a role in fixing and supporting other components. The heat absorber 3 and the grid 4 are both arranged in the frame 1, and the heat absorber 3 is positioned on the grid 4. The heat absorber 3 is used for absorbing solar energy and converting the solar energy into heat energy for use.

In this embodiment, the frame 1 is a rectangular frame, and may be made of an alloy material, such as an aluminum alloy material, and has the advantages of light weight, low cost, and good strength.

In order to protect the heat absorber 3 and the internal grid 4, the heat collector further comprises a glass cover plate 2, wherein the glass cover plate 2 is arranged at the top of the frame 1 and used for shielding and protecting the heat absorber 3 and the grid 4 and preventing foreign objects from entering the interior of the heat collector, so that the heat absorber 3 and the like are prevented from being damaged.

In order to fix the glass cover plate 2 conveniently, the top parts of at least two sides of the frame 1 can form a U-shaped accommodating groove through a bending process, the edge of the glass cover plate 2 is accommodated in the accommodating groove, and the glass cover plate 2 and the frame 1 are installed.

Optionally, the glass cover plate 2 and the frame 1 may be fixed by other means, such as adhesive bonding, which is simple, firm and low in cost.

In order to avoid the abrasion of the heat absorbing body 3, the heat absorbing body 3 and the glass cover plate 2 are arranged at intervals, the gap between the heat absorbing body 3 and the glass cover plate 2 can be about 20mm, the gap can be controlled within a small range to reduce the loss of heat generated by air in the gap to the heat collector, the heat absorbing body 3 can be ensured not to be in contact with the glass cover plate 2, and therefore the heat absorbing body 3 is ensured not to be abraded.

In this embodiment, the grid 4 includes a plurality of pipelines extending along the length direction of the frame 1, and the pipe diameter of the pipeline is small, and the length is long, which can reach about two meters, resulting in that the grid 4 is easy to deform when being welded. The deformation of the grid 4 will cause the pipe to bend and easily push the heat absorber 3 to move closer to the glass cover plate 2, causing the heat absorber 3 to contact the glass cover plate 2 and causing wear. In addition, when the collector is inverted during transportation or transportation, the grid 4 is prone to bending under the action of gravity, which also causes the heat absorbing body 3 to be worn away from the glass cover plate 2.

In order to solve the above problem, in this embodiment, the heat collector further includes a grid fixing member 5, and the grid fixing member 5 is disposed in the frame 1 and connected to the grid 4, so as to limit the movement of the grid 4 in the frame 1, and reduce the deformation of the grid 4, so as to shape the grid 4, and further avoid the abrasion of the heat absorbing body 3.

Specifically, as shown in fig. 2 and 3, the grid fixing member 5 includes a support portion 51 and a fixing portion 52. One end of the supporting part 51 is used for abutting against the frame 1 in the heat collector, and the other end is used for supporting the glass cover plate 2 in the heat collector, so that the grid fixing part 5 can be fixed in the frame 1 by matching the supporting part 51 with the glass cover plate 2 and the frame 1, the grid fixing part 5 is prevented from moving, and the grid 4 connected with the grid fixing part is prevented from moving.

The fixing portion 52 has one end connected to the support portion 51 and the other end connected to the grid 4, and the fixing portion 52 limits the position of the grid 4, thereby preventing the heat absorbing body 3 from being damaged due to the movement of the position of the grid 4. The fixing portion 52 is connected to the grid 4, and can also play a certain role in restraining the grid 4, so as to limit the deformation of the grid 4 by the acting force between the grid 4 and the grid, thereby further avoiding the damage of the heat absorbing body 3. The constraint force applied to the grids 4 by the fixing parts 52 can also play a role in shaping the grids 4 with certain deformation after welding, correct the deformation of the grids and further ensure that the heat absorbing body 3 is not worn.

Compared with the prior art in which the grids are fixed by using leftover steel sheets or thin iron wires, the grid fixing piece 5 supports the glass panel through the supporting part 51, and the fixing part 52 is connected with the grid 4, so that the installation positions of the glass cover plate 2 and the grid 4 can be further ensured, and the heat absorber 3 is prevented from being damaged due to movement or deformation of the glass cover plate and the grid 4.

In the prior art, the frame is not provided with a structure matched with leftover material steel sheets or thin iron wires, so that the installation position of the leftover material steel sheets or the thin iron wires is limited, and the frame is arranged at the tail end of a pipeline in a grid, so that the limit or correction effect on the deformation of the pipeline is limited, and the problem of abrasion of a heat absorbing body still exists.

In this embodiment, the grid fixing member 5 is fixed between the frame 1 and the glass cover plate 2 by the support portion 51, so that the fixing position is more flexible, the grid fixing member 5 can be installed at any position in the frame 1, and the use is more flexible.

In addition, a connecting structure with the grid fixing piece 5 does not need to be added on the frame 1, the structure of the frame 1 does not need to be redesigned, the existing frame is used, and the compatibility is good.

In other embodiments, the bottom end of the supporting portion 51 may not abut against the frame 1, and the supporting portion 51 may be fixedly connected to the frame 1 by a fastener, so as to make the installation of the grid fixing member 5 more stable.

In this embodiment, the supporting portion 51 is vertically disposed, and the fixing portion 52 may be horizontally disposed, so that the supporting portion 51 and the fixing portion 52 form a T shape, and the T-shaped structure is beneficial to improving the strength of the grid fixing member 5.

In order to reduce the space occupied by the grid mount 5, both the support portion 51 and the fixing portion 52 may have a plate-like structure, and the mass of the grid mount 5 may also be reduced.

Further, the supporting portion 51 may be disposed closely to the inner wall of the frame 1, so that the frame 1 provides support for the grid fixing member 5, which is beneficial to improving the strength and fixing effect of the grid fixing member 5.

Alternatively, one end of the support portion 51 contacting the glass cover plate 2 may have elasticity. The specific elasticity of one end of the support part 51 in contact with the glass cover plate 2 can increase the clamping and fixing effect of the glass cover plate 2 and the frame 1 on the grid fixing piece 5, and can better fix the grid fixing piece 5.

In addition, the supporting part 51 has elasticity at one end contacting with the glass cover plate 2, so that the supporting part 51 can be prevented from scratching the glass cover plate 2, and the surface quality of the glass cover plate 2 is ensured.

Alternatively, one end of the support portion 51 supporting the glass cover plate 2 may be an arc-shaped structure 511 bent toward the grid 4. The arc-shaped structure 511 not only can increase the elastic coefficient of the supporting portion 51, but also can increase the contact area between the supporting portion 51 and the glass cover plate 2, which is beneficial to improving the fixing effect of the grid fixing member 5.

In order to facilitate the connection between the fixing portion 52 and the pipes in the grid 4, a slot may be disposed on the fixing portion 52, and the pipes in the grid 4 may be connected to the fixing portion 52 by being clamped in the slot. The fixing part 52 is connected with the grid 4 through clamping, so that the connection is convenient and the structure is simple.

Optionally, the grid fixing member 5 may further include an arc plate 53, the arc plate 53 may be disposed on the fixing portion 52, and the arc plate 53 encloses a slot that is formed to cooperate with the grid 4 pipe. The clamping groove is formed by the arc-shaped plate 53, so that the fixing part 52 can be prevented from being directly provided with a groove, and the strength of the fixing part 52 is improved.

As shown in fig. 4, in order to improve the strength of the grid fixing member 5, prevent the grid fixing member 5 from being deformed, and thus improve the shaping effect of the grid fixing member 5 on the pipes in the grid 4, the grid fixing member 5 further includes reinforcing ribs 54, and the supporting portions 51 and the fixing portions 52 are respectively connected to adjacent sides of the reinforcing ribs 54, thereby improving the strength of the grid fixing member 5.

Alternatively, the ribs 54 may have a triangular configuration, which is advantageous in improving the stability of the grid fixing member 5.

Alternatively, the reinforcing ribs 54 may be provided with through holes to reduce the weight of the reinforcing ribs 54, thereby reducing the load of the frame 1 and preventing the frame 1 from being deformed.

Optionally, the fixing portion 52 is located between the arc-shaped structure 511 and the reinforcing rib 54 for supporting the glass cover plate 2, and the fastening groove is disposed on one side of the fixing portion 52 close to the glass cover plate 2, so that the fixing portion 52 can apply a force to the pipes of the grid 4, which is away from the direction of the glass cover plate 2, thereby further preventing the pipes from protruding to one side close to the glass cover plate 2, and further preventing the heat absorbing body 3 from being worn.

Because the pipeline deformation is concentrated in the middle position of pipeline along length direction in grid 4 more, so in this embodiment, grid mounting 5 can be connected with the middle part of pipeline, is favorable to reducing the deformation of pipeline.

Alternatively, as shown in fig. 5, the grid fixing member 5 may be provided in plurality, and a plurality of grid fixing members 5 are symmetrically distributed on both sides of the grid 4.

The embodiment also provides a water heater which comprises the heat collector, so that the abrasion of the heat absorbing body 3 is reduced, and the working efficiency and the quality of the water heater are improved.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
