Description

Novel circulating connecting pipe of flat-plate solar water heater

Technical Field

The utility model relates to a circulating connecting pipe of a solar water heater, in particular to a cold and hot water circulating connecting pipe of a flat-plate solar water heater.

Background

At present, a flat-plate solar water heater integrated machine is mainly divided into three parts, wherein the first part is a flat-plate solar heat collecting plate; the second part is a heat storage water tank; the third part is a cold and hot water circulation connecting pipe for connecting the flat solar heat collecting plate and the heat storage water tank. The flat solar heat collecting plate is arranged at the lower part of the hot water storage tank, the two parts cannot be directly connected, the flat solar heat collecting plate and the hot water storage tank are connected through two circulating connecting pipes, and hot water heated by the flat solar heat collecting plate flows into the upper part of the hot water storage tank through a hot water end circulating connecting pipe according to the siphon principle; the water with lower temperature at the lower part of the water storage tank flows into the flat-plate solar heat collecting plate through the cold water end circulating connecting pipe, and the water is heated continuously in a circulating way.

In the current market, the first part is a flat solar heat collecting plate and the second part is a very standard mature product, but the third part is a cold and hot water circulating connecting pipe which is basically not a mature formed product, so that the third part is basically a salesperson for claiming, the installation constructor can be installed on site, the construction randomness is very high, and the condition of temporarily charging the cost during installation is very common.

The second part of the heat storage water tank is divided into a pressure-bearing water tank and a non-pressure-bearing water tank, and the common installation method of the circulating connecting pipe corresponding to the non-pressure-bearing water tank at present is as follows: firstly, a heat-resistant plastic pipe (an aluminum plastic pipe or a PPR pipe) is selected as an internal liquid flowing and conveying pipeline, the pipeline is cut off according to the actual length, then the shape of a bending circulating pipe is installed and arranged according to the positions of a flat solar heat collecting plate and a heat storage water tank, threads are processed on site for the pipeline or a connecting joint is installed, and then a hot water end and a cold water end of the connecting circulating pipe are respectively connected with the flat solar water heater and the heat storage water tank. And secondly, wrapping the heat-insulating pipe outside the water conveying pipeline, firstly cutting the heat-insulating pipe when wrapping the heat-insulating pipe, then wrapping the heat-insulating pipe on the conveying pipeline, then smearing glue on the heat-insulating pipe notch, and after the glue is fully volatilized, adhering the cut heat-insulating pipe notch. And thirdly, winding a protective tape on the outer layer of the heat preservation pipe to strengthen the ultraviolet resistance, ageing resistance and waterproofness of the heat preservation pipe. The usual method for the installation of the circulation pipes of a pressure-bearing heat storage tank is: firstly, selecting a heat-resistant and pressure-resistant metal pipeline as a circulating pipeline, and usually selecting a copper pipe or a stainless steel pipe, wherein the copper pipe or the stainless steel pipe is required to be bent into a corresponding shape, the copper pipe or the stainless steel pipe is not easy to bend in an installation site, the copper pipe or the stainless steel pipe is required to be prefabricated and bent in advance, and the prefabricated and bent volume in advance is very large; the other way is to select a metal hose, but the metal hose cannot be ensured to be flat, the installation appearance cannot be well matched with the flat solar heat collecting plate, and the installation is not attractive, so that the installation effect of the flat water heater integrated machine of the pressure-bearing heat storage water tank is not good at present. The second step and the third step of the installation of the circulating pipeline of the pressure-bearing heat storage water tank are the same as the installation method of the circulating pipeline of the non-pressure-bearing water storage tank, namely, a heat preservation layer and an ultraviolet-resistant anti-aging layer are added.

So the current market common situation is: in terms of quality control, the circulating pipeline installation of the flat-plate solar water heater integrated machine is a matter with large workload, more working procedures and difficult quality control. In terms of cost control, the circulating pipeline of the flat-plate solar water heater integrated machine is large in waste of installation materials, labor cost is continuously and rapidly increased, and installation and construction cost is continuously increased. In terms of sales management, the circulating pipeline of the flat-plate solar water heater integrated machine is not easy to sell independently because of no formed complete product, is basically introduced orally by sales staff, is randomly installed on site by construction staff, and has a plurality of conditions of temporarily charging. In terms of consumer purchase, the circulation pipeline of the flat-panel solar water heater integrated machine is also free of ready-made forming complete products, so that the formed products cannot be seen actually before purchase, the situation that the imagination effect of the consumer and the actual installation effect are quite different frequently occurs, and complaints often occur. So that a great part of consumer complaints of the existing flat-plate solar water heater integrated machine occur in the circulating pipe part.
