Abstract

The utility model discloses a heat collecting tube water storage type solar water heater, which comprises an automatic water replenisher and a heat collector. There are hot water outlet pipes, and the heat collector has multiple heat collecting pipes connected in series through the inner connecting pipe. The upper end of each heat collecting pipe is installed in the shell, and the lower end is installed on the end box of the bracket. into the bottom of the collector tube. The utility model uses a diversion tube to extend into the bottom of the heat collecting tube, so that the cold water entering from the automatic water replenisher directly enters the bottom of the heat collecting tube, and the hot water discharged from the terminal is repeatedly heated by multiple heat collecting tubes. relatively short time. The uppermost end of the overflow pipe is higher than the automatic water replenisher, so that cold water will not flow out, and when the water in the collector expands, hot water can flow out from the overflow pipe, avoiding the explosion of the pipe.

Description

Collector tube water storage solar water heater

technical field

The utility model belongs to a solar water heater, in particular to a heat collecting tube solar water heater.

Background technique

A solar water heater is a common device that utilizes solar energy to provide hot water for people. There is an integral water tank type, which is generally composed of a heat collecting tube and a water storage tank. When in use, it is heated as a whole, the temperature rises relatively slowly, and the temperature is relatively low. There is also a series water supply type solar water heater, such as the series water supply type solar water heater disclosed in Chinese patent 200620009410.3, which is connected in series by a plurality of heat collecting pipes through connecting pipes, which increases the contact area between water and heat collecting pipes, although the temperature rise is higher than before , but the temperature rise is slower and the temperature is lower.

Contents of the invention

The purpose of the utility model is to provide a heat-collecting tube storage type solar water heater with fast temperature rise and high temperature.

The technical scheme of the utility model is: a heat collecting tube water storage type solar water heater, including an automatic water replenisher and a heat collector, the automatic water replenisher is provided with a water inlet, the automatic water replenisher is connected to the heat collector through a connecting pipe, and the heat collector There is a hot water outlet pipe on the collector, and the heat collector has multiple heat collecting pipes connected in series through the inner connecting pipe. The upper end of each heat collecting pipe is installed in the shell, and the lower end is installed on the end box of the bracket. The connecting pipe communicates with the diversion pipe. The draft tube extends into the bottom of the heat collecting tube.

The above-mentioned heat collecting tube water storage type solar water heater is also provided with an overflow pipe on the guide pipe, and the uppermost end of the overflow pipe is higher than the automatic water replenisher.

In the heat collecting tube water storage type solar water heater mentioned above, the bracket end box has a built-in thermal insulation material.

The above-mentioned heat collecting tube water storage type solar water heater is provided with valves on the water inlet pipe and the water outlet pipe.

Beneficial effects of the utility model: Since the diversion pipe extends into the bottom of the heat collection pipe, the cold water entering from the automatic water replenisher directly enters the bottom of the heat collection pipe, and the process of slowly overflowing is also the process of heating through the heat collection pipe The hot water heated through the first stage enters the bottom of the next heat collecting tube through the guide tube and is heated again and flows to the next heat collecting tube. In this way, the temperature of the hot water discharged from the terminal through repeated heating is relatively high, and the utilization time is relatively short. The uppermost end of the overflow pipe is higher than the automatic water replenisher, so that cold water will not flow out, and when the water in the collector expands, hot water can flow out from the overflow pipe, avoiding the explosion of the pipe.

The utility model has the advantages of low cost, simple structure and convenient maintenance, and is suitable for household water use, and multiple sets can be used in central hot water supply projects.

Detailed ways

The collector tube water storage solar water heater shown in Figure 1 and Figure 2 includes an automatic water replenisher 1 and a heat collector 2, the automatic water replenisher 1 is provided with a water inlet 7, and the automatic water replenisher 1 is connected to the heat collector through a connecting pipe 6 On the heat collector 2, a hot water outlet pipe 9 is provided on the heat collector 2. The heat collector 2 has a plurality of heat collection pipes 5 connected in series through the inner connecting pipe 14. The upper end of each heat collection pipe is installed in the shell 4, and the lower end is installed in the bracket 3 The tail box 10, the connecting pipe communicates with the guide tube 8, and the guide tube 8 extends into the bottom of the heat collecting tube 5. An overflow pipe 11 is also provided on the diversion pipe 6, the uppermost end of the overflow pipe 11 is higher than the automatic water replenisher, the bracket tail box 10 has a built-in thermal insulation material, a valve 12 is set on the water inlet pipe 7, and a valve is set on the water outlet pipe 9 13.

For the above-mentioned heat-collecting-tube water-storage solar water heater, the heat collector 2 can also have seven or eight or more heat-collecting pipes connected in series, the more heat-collecting pipes, the higher the temperature of the obtained hot water.

Working process: When in use, cold water enters the diversion tube of the heat collecting tube from the automatic water replenisher and then enters the next heat collecting tube. The temperature of the water heated repeatedly through multiple heat collecting tubes is higher. The hot water outlet pipe 13 has flowed out for people to use.
