Description

A double tank solar water heater

technical field

The utility model belongs to the technical field of solar energy utilization and relates to a solar water heater, in particular to a double-tank solar water heater.

Background technique

Solar water heaters can use solar energy to convert internal energy into water. On the one hand, it reduces the coal, natural gas or electricity used in the water heating process. On the other hand, solar water heaters have a relatively long life, and one-time investment can benefit long-term. Therefore, the installation of solar water heaters in our country is increasing year by year. The solar water heater with larger usage at present is a single box structure solar water heater, and the water storage tank is directly connected with the heating vacuum tube, and the hot water produced is all stored in the water storage tank.

The above-mentioned solar water heater with a single box structure is simple in structure, but there are many problems as follows during use:

(1) The water temperature rises slowly. Since the heating pipe is directly connected to the water storage tank, the volume of the water storage tank is relatively large, and it is difficult for the vacuum heat collecting tube to rapidly increase the water temperature in the water storage tank;

(2) Water circulation is slow. The vacuum heat collecting tube circulates and heats the water source in the whole water storage tank. Due to the relatively large volume of the water storage tank, the speed of circulating water becomes slow.

The circulating water speed of the single-box structure solar water heater is slow, and the water temperature rises slowly, which is increasingly unsuitable for the needs of customers.

Utility model content

The utility model provides a double-tank solar water heater in order to solve the shortcomings of the prior art. A heat insulation board is added to the water storage tank, and a high-temperature water tank and a low-temperature water tank are separately provided.

The technical scheme of the utility model is as follows:

A double-tank solar water heater is composed of an insulated tank, a high-temperature water tank, a low-temperature water tank, a vacuum heat collecting tube, a water inlet, a water outlet and an exhaust port.

The high-temperature water tank and the low-temperature water tank are installed inside the insulated box with the upper and lower structures, the water inlet is connected with the low-temperature water tank, the water outlet and exhaust port are connected with the high-temperature water tank, and the vacuum heat collecting tube is connected with the low-temperature water tank.

The low-temperature water tank also includes a heat shield, a water riser, a one-way port cover, and a honeycomb hole. The heat shield is a right-angle structure, which is used to divide the low-temperature water tank and the high-temperature water tank; the center of the upper end surface of the heat shield has a riser, and the upper end of the riser faces the high-temperature water tank to install a one-way cover; the lower end of the side wall of the heat shield It has honeycomb holes to connect the high temperature water tank with the low temperature water tank.

During use, the vacuum heat collecting tube heats the water source, the high temperature water rises in the low temperature water tank, pushes the one-way cover through the water riser to enter the high temperature water tank, and the cold water in the high temperature water tank will be located at the lowest end of the high temperature water tank and enter the low temperature water tank through the honeycomb holes. This large circulation structure can ensure that the water temperature in the high-temperature water tank will always be higher than that of the low-temperature water tank.

When the water outlet discharges water, because the honeycomb aperture is small, the overwhelming majority that directly flows into the water outlet is the high-temperature water in the high-temperature water tank, which ensures the water temperature of the water outlet. When the water source in the high temperature water tank is exhausted, the water source in the low temperature water tank will flow into the high temperature water tank through the honeycomb holes to ensure the timeliness of water use. At this time, because the high temperature water tank is in a state of water shortage, the water pressure in the low temperature water tank is relatively high. The water outlet speed of the honeycomb holes can meet the flow requirements of the water outlet.

Effect and benefit of the present utility model are:

(1) For the double-tank solar water heater, the high-temperature water tank and the low-temperature water tank are installed inside the incubator in a vertical structure, and the heating water source is managed separately to improve the use performance of hot water;

(2) The heat shield separates the high-temperature water tank from the low-temperature water tank to ensure that the temperature of the water source in the high-temperature water tank is always at a high temperature;

(3) The water riser, one-way cover, and honeycomb hole structure of the heat insulation board not only ensure that the high-temperature water tank always stores high-temperature water source, but also ensure that when the high-temperature water tank is short of water, the water source flows directly from the low-temperature water tank through the honeycomb hole to the water outlet. Enhance its functionality and practicality.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

A double-tank solar water heater, as shown in Figure 1 of the specification, consists of an incubator 1, a high-temperature water tank 2, a low-temperature water tank 3, a vacuum heat collecting tube 4, a water inlet 5, a water outlet 6 and an exhaust port 7.

The low-temperature water tank 3 also includes a heat shield 31 , a water riser 32 , a one-way cover 33 , and a honeycomb hole 34 . The heat insulation board 31 is a right-angle structure, which is used to divide the low-temperature water tank 3 and the high-temperature water tank 2; the center position of the upper end surface of the heat insulation board 31 has a riser 32, and the upper end of the riser 32 is facing the high-temperature water tank 2. A one-way cover 33 is installed; The lower end of the side wall surface of the heat insulation board 31 has honeycomb holes 34 to connect the high-temperature water tank 2 and the low-temperature water tank 3 .

Example

During use, the vacuum heat collecting tube 4 heats the water source, the high-temperature water rises in the low-temperature water tank 3, and pushes the one-way cover 33 to enter the high-temperature water tank 2 through the rising water port 32, and the cold water in the high-temperature water tank 2 will be located at the lowest end of the high-temperature water tank 2 Enter the low-temperature water tank 3 through the honeycomb hole 34.

When water outlet 6 discharges water, because honeycomb hole 34 apertures are little, the overwhelming majority that directly flows into water outlet 6 is the high-temperature water in the high-temperature water tank 2. After the water source in the high-temperature water tank 2 is exhausted, the water source in the low-temperature water tank 3 will flow into the high-temperature water tank 2 through the honeycomb hole 34 to ensure the timeliness of water use. The water pressure is relatively high, and the water outlet speed of the honeycomb hole 34 can meet the flow requirement of the water outlet 6.
