The invention relates to a heat collecting device of a water heating system, in particular to a heat collecting board achieving flow channel same-stroke constant pressure distribution. According to the heat collecting board, working media in a flow channel are evenly distributed, and the effective heat collecting area can be enlarged. The heat collecting board comprises a board body and the working medium flow channel formed inside the board body. The working medium flow channel comprises main flow channels and branch flow channels. The board body is provided with a master flow channel inlet and a master flow channel outlet. The master flow channel inlet is connected with the main flow channels through a same-stroke flow divider. The main flow channels are the same in flow stroke. The other end of each main flow channel is connected with the branch flow channels through a same-stroke flow divider. The branch flow channels are the same in flow stroke. Each branch flow channel is provided with a reducing section. The reducing sections are the same in length and diameter. The tail ends of the branch flow channels are gathered and then are connected with the master flow channel outlet. The master flow channel outlet is formed in the upper end of the board body. According to the heat collecting board achieving flow channel same-stroke constant pressure distribution, by means of the same-stroke constant pressure distribution of the working medium flow channel, the working media are evenly distributed in the working medium flow channel, the effective heat collecting area is enlarged, and the heat collecting effect is improved.
Description
technical field [0001] The invention relates to a heat-gathering device of a hot water system, in particular to a heat-gathering plate with equal-pressure distribution of flow channels on the same course. Background technique [0002] At present, the space between the flow channels of the solar heat collecting plate is relatively large, the distribution of the working medium in the flow channel is uneven, and the heat collecting effect is poor. The heat accumulation is slow, the heat accumulation efficiency is low, and the flow channel of the heat accumulation plate is relatively sparse, resulting in a large area and affecting installation. Contents of the invention [0003] The object of the present invention is to provide a heat-gathering plate in which the working medium in the flow channel is evenly distributed and the effective heat-gathering area can be increased in order to solve the deficiencies of the above-mentioned technologies. [0004] In order to achieve the...
