Description

Split solar water heater tank

technical field

The utility model belongs to parts of solar water heaters, in particular to a pressure-bearing water tank.

Background technique

The water tank is an important part of the split solar water heater. Usually the heat collector is installed outdoors and the water tank is installed indoors. Chinese patent CN2890754 discloses a split solar water heater. The vertical height of the hot water outlet on the water storage tank of the water heater is high The vertical height of the water outlet on the collector. After the cold water absorbs solar energy and heats up, its specific gravity decreases, and it will automatically flow upwards and enter the hot water storage tank, while the cold water in the hot water storage tank will flow out under pressure and enter the sewage circulation connection tank as a supplement, thus eliminating the need for a closed heat transfer medium. Realize the natural circulation of cold and hot water. Although the problem of not using heat transfer medium is solved, the hot water outlet of the water heater is installed at the bottom of the water tank. When the relative height of the water storage tank is installed at a low level, the hot water has no pressure and the hot water nozzle comes out Powerless and inconvenient, and the water temperature at the bottom of the water tank is low when the heating time is short.

Utility model content

In order to overcome the shortage of low water outlet pressure in the existing water tank, the utility model provides a split type solar water heater water tank, which not only has high water outlet pressure, but also makes full use of the hot water at the top of the water tank.

The technical solution adopted by the utility model to solve the technical problem is: a split type solar water heater water tank, including a water tank body and a heat preservation layer, characterized in that the lower part of the horizontally installed water tank body has a circulating hot water inlet and a circulating cold water outlet , cold water inlet, hot water outlet, the top of the circulating hot water inner pipe connected to the circulating hot water On the top of the water tank, the top of the circulating cold water inner pipe connected with the circulating cold water outlet is located at the bottom of the water tank, and the top of the cold water inlet pipe connected with the cold water inlet is located at the bottom of the water tank.

An auxiliary electric heater is housed in the water tank.

The upper mouth of the cold water inlet pipe is closed, and there are at least three horizontal water outlet holes around the water pipe near the upper mouth.

The water tank body is provided with a safety valve.

The cold water inlet is provided with a pressure limiting valve.

The water tank is equipped with temperature and pressure sensors and is connected with an electrical controller installed outside the water storage tank.

Since the circulating hot water inlet of the utility model is equipped with a circulating hot water pipe whose top is higher than the center line of the water tank, due to the low density of the hot water, the hot water first concentrates on the upper half of the water tank and gradually goes downward, and the hot water outlet is connected to the heat pipe near the top of the water tank. Water outlet pipe, when using hot water, open the cold water inlet and push the hot water to be discharged from the hot water outlet under the pressure of cold water. No matter the relative height of the water tank is high or low, the hot water has the same pressure as cold water, and the water spray effect is good, and the discharge is good The hot water with higher temperature at the top of the water tank overcomes the disadvantage that the hot water outlet is located at the bottom of the water tank to discharge low-temperature water in the prior art. The auxiliary electric heater can be used normally in rainy weather, and the temperature and pressure sensors, safety valves, and pressure limiting valves are beneficial to realize automatic control and ensure the safety of the equipment.

The utility model discloses that the water tank of the solar water heater operates under pressure even when the relative height of the water storage tank is relatively low. It is suitable for residents of small high-rise and high-rise buildings.
