Sheet type solar water heater

Abstract

The invention relates to a panel-typed solar water heater, belonging to the product utilizing solar energy to heat water and mainly aiming at solving the technical problems of water heating efficiency and freeze proof. The technical scheme is that a water inlet pipe (1) is installed on a control box (2); a water control valve is arranged in the control box; a water inlet pipe (3) arranged at the lower part is led to a hot water collecting box (4); a steam discharge pipe (5) is arranged at the top of the hot water collecting box (4); a water outlet pipe (6) is also arranged at the top; a hot water inlet pipe (7) and a cooling water outlet pipe (11) are led to the bottom of the hot water collecting box; the hot water inlet pipe (7) is connected with an upper water pipe of a heat absorption plate (9); the cooling water outlet pipe (11) is connected with a lower water pipe of the heat absorption plate (9); a drain pipe (10) is arranged; and the heat absorption plate is arranged in an insulating box (8). The invention can be used for utilizing solar energy to produce hot water.

Description

1. Technical field [0001] The invention relates to a solar water heater, in particular to a chip type solar water heater whose heat absorbing plate is a sheet. 2. Background technology [0002] There are three basic types of common solar water heaters at this stage. One is the traditional flat plate type, which has the disadvantage of low heat absorption efficiency and is not very frost-resistant; the second is the vacuum tube type, which has the disadvantage of high cost and is not very resistant to hail. ; The third is the auxiliary electric heating type, its defect is that it is inconvenient to install, there is a potential safety hazard in use, it needs power consumption, and it increases the cost of use. [0003] In addition, since the implementation of the patent system in our country, many technical products related to solar water heaters have applied for national patents, no less than a thousand, which shows that this type of technology has attracted the attention an...

[0002] There are three basic types of common solar water heaters at this stage. One is the traditional flat plate type, which has the disadvantage of low heat absorption efficiency and is not very frost-resistant; the second is the vacuum tube type, which has the disadvantage of high cost and is not very resistant to hail. ; The third is the auxiliary electric heating type, its disadvantage is that it is inconvenient to install, there are potential safety hazards in use, it needs power consumption, and it increases the cost of use

[0006] For this reason, flat-plate solar water heaters are mainly solved by adding heat-absorbing fins, but no one has raised doubts about this long-term method. In addition, the design of hot water circulation pipelines has not considered too much the self-accelerating cycle of heat flow. ability to improve, moreover, the means of anti-freeze have not been considered from the structural design
