Problems solved by technology

If the temperature of the heat collecting plate is almost the same as the temperature of the water in the indoor water tank, or more seriously, the temperature of the heat collecting plate is lower than the temperature of the water in the indoor water tank, the solar water heater described above will not work properly, because the water in the heat collecting plate The working medium can no longer transfer the internal energy absorbed by the heat collecting plate to the water in the water tank
And this kind of situation usually happens when the lighting conditions are not particularly good, such as in the evening or on cloudy days, and usually at this time the collector plate is still absorbing solar energy, but it cannot transfer this part of the internal energy to the water in the tank , so that the solar energy utilization rate of the whole solar water heater is not very high

Embodiment 1

[0026] figure 1 An axonometric view showing an embodiment of the collector plate in the solar heat pump collector of the present invention, please refer to figure 1 , the first working medium circulation channel in the heat collecting plate in this embodiment is composed of a plurality of parallel first channels 111 arranged in the heat collecting plate and a first elbow 113 connecting two adjacent first channels, The second working medium circulation channel is composed of a plurality of parallel second channels 112 arranged in the heat collecting plate and a second elbow 114 connecting two adjacent second channels. The heat collecting plate in this embodiment is an integral plate structure, and the section along the arrangement direction of the first channel and the second channel is zigzag.

[0027] Those skilled in the art should be able to understand that the first channel and the second channel meeting the above conditions can be divided into two regions on the heat col...

Embodiment 2

[0031] This embodiment provides a heat collecting plate with another structure. The difference between the heat collecting plate and the heat collecting plate in Embodiment 1 is that the heat collecting plate is spliced ​​together by a plurality of heat collecting plate units by buckling. , this method can facilitate the processing of the heat collecting plate, form a modular processing, and is convenient for transportation and installation.

[0032] specifically, figure 2 shows an axonometric view of the collector plate, image 3 for figure 2 Left view of the collector plate in, Figure 4 for figure 2 Right view of the collector plate in . See also Figure 2 to Figure 4 , the first working medium circulation channel in the heat collecting plate is still composed of multiple parallel first channels 111 arranged in the heat collecting plate and the first elbow 113 connecting two adjacent first channels, the second working medium The medium circulation channel is still ...

Abstract

The embodiment of the invention provides a bent solar heat pump heat collector, which comprises a first heat collecting plate, wherein a first working medium flow passage and a second working medium flow passage are arranged in the heat collecting plate; a first working medium inlet is formed in one end of the first working medium flow passage, and a first working medium outlet is formed in the other end of the first working medium flow passage; a second working medium inlet is formed in one end of the second working medium flow passage, and a second working medium outlet is formed in the other end of the second working medium flow passage; the first working medium flow passage is communicated with a first working medium heat exchanger in a water tank through a pipeline to form a solar heat exchange circulation loop; the second working medium flow passage is communicated with a condenser in the water tank and a compressor outside the water tank through pipelines to form a heat pump circulation loop; and the section of the heat collecting plate in the arrangement direction of the first passage and the second passage is saw-toothed.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a bent solar heat pump heat collector. Background technique [0002] Because of energy saving and environmental protection, solar technology has been widely used in daily life. For example, the application of solar technology in the field of water heaters has formed solar water heaters. [0003] A common solar water heater includes a heat collector and a water tank. The heat collecting plate in the heat collector receives solar energy, the temperature rises, and heats the working medium circulating in the heat collecting plate. After the temperature rises, the working medium flows through the water tank through the pipeline. , to exchange heat with the water in the water tank. During the heat exchange process, the temperature of the water in the water tank increases and the temperature of the working medium decreases; Heat; cycle like this. [0004] But the precondition t...
