Description

A split solar pressurized water tank

Technical field:

The utility model relates to a split solar pressurized water tank.

Background technique:

In the existing split solar products, the heat exchange between the pressurized water tank and the heat transfer medium and the expansion of the medium have always been technical problems that plague the popularization and application of split products. At present, the commonly used split solar pressurized water tank is to place a small inner tank in the inner tank of the water tank. The small inner tank is equipped with a medium circulation inlet and outlet. Through the medium circulation, it exchanges heat with the water in the water tank, and the heat exchange area is small. The efficiency is slow, and the problem of medium expansion cannot be solved at the same time.

Invention content:

The purpose of this utility model is to solve the problems of the existing pressurized water tanks such as low heat exchange efficiency, medium expansion, affecting normal use, etc., and provide a simple structure, convenient installation, good heat exchange effect, and solve the advantages of medium expansion, etc. Split solar pressurized water tank.

In order to achieve the above object, the utility model adopts the following technical solutions:

A split solar pressurized water tank, which includes a water tank liner, a jacketed medium liner is arranged outside the water tank liner, a heat-conducting medium inlet pipe and a heat-conducting medium outlet pipe are provided in the medium liner, and the top of the medium liner is connected to the inside of the water tank There is an expansion cavity at the top of the gallbladder.

The medium liner is welded and fixed to the bottom of the water tank liner.

The heat transfer medium inlet pipe and the heat transfer medium outlet pipe are connected to the heat collector through copper pipes.

The utility model comprises a medium liner and a water tank liner, the bottom of which is welded and fixed together, and the medium liner is provided with a circulating medium inlet pipe and a circulating medium outlet pipe, both of which are connected to the heat collector through copper pipes. At the same time, the unique expansion cavity of the water tank is used to balance the expansion pressure during the medium circulation process, eliminating the need for a separate expansion tank.

The beneficial effect of the utility model is that the structure is simple, the installation is convenient, and the unique expansion cavity is used to balance the expansion pressure in the process of medium circulation, and a separate expansion tank is omitted.

Description of drawings:

Fig. 1 is the utility model sectional structure schematic diagram;

Fig. 2 is a schematic diagram of the bottom surface structure of the utility model.

In the figure: 1. Medium liner; 2. Expansion cavity; 3. Water tank liner; 4. Medium inlet pipe; 5. Medium outlet pipe.

Detailed ways:

The utility model will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the utility model includes a medium liner 1 and a water tank liner 3, the bottom of which is welded and fixed together, and the medium liner is provided with a circulating medium inlet pipe 4 and a circulating medium outlet pipe 5, both of which pass through copper The tubes are connected to the collector. At the same time, the specific expansion cavity 2 of the water tank is used to balance the expansion pressure during the medium circulation process, eliminating the need for a separate expansion tank.

When in use, connect the outlet and inlet of the circulating medium of the split pressurized water tank to the interface of the heat collector. The heat collector absorbs heat, heats the medium, and returns to the medium liner of the water tank through the medium entrance of the water tank. The medium in the medium liner and the water tank The water in the gallbladder conducts heat exchange to achieve the purpose of heating water. As the temperature of the medium in the medium circulation system rises, the system pressure increases, and the cavity on the upper part of the medium liner is used to balance the pressure and protect the left and right of the liner.
