Description

Water tank of a split type solar water heater

technical field

The utility model relates to a solar water heater, in particular to a separate cavity water tank with a built-in heat exchanger of the split solar water heater.

Background technique

1. The water tank of the split type solar water heater is generally a complete cavity. When in use, after tap water enters the water tank, the hot and cold water will have a mixed temperature phenomenon. Water needs one day or more, and the characteristics of long heating cycle are very inconvenient to use water and waste energy.

2. This utility model solves the problem of how to combine the pressurized solar water tank with the non-pressurized solar collector. The hot water used is pressurized (to solve the problem of automatic water supply), and the heat exchange part is not under pressure Yes, non-pressurized vacuum tube solar collectors can be used instead of expensive collectors such as "heat pipes" or "U" tubes, which reduces the cost.

3. Double circulation mode, natural circulation heat exchange, no need for water pump, no scale in the collector.

Utility model content

The main task of the utility model is to provide a split-type solar water heater with a built-in heat exchanger and an isolated water tank with fast heat collection and high hot water utilization rate.

In order to solve the above technical problems, a water tank of a split type solar water heater of the present invention includes components such as a water tank shell and a water tank liner. Heat exchanger, the stainless steel connected to the head part is used as a part of the heat exchanger, and the heat exchanger and the inner tank of the water tank are sealed with non-metallic sealing materials, and the inner tank of the water tank is separated into several cavities. There is one guide flow tube at the seal of the inner tank; and the upper circulation tube between the heat exchangers is made into a T-shaped structure and connected to the medium tank.

The water tank liner cavity is divided into three cavities.

One end of the drainage tube is at the upper end of the seal between the heat exchanger and the water tank liner, and the other end extends into the bottom of the other cavity.

The exhaust pipe of the heat exchanger is built in the heat exchanger, and the length of the exhaust pipe is slightly shorter than that of the heat exchanger.

The water tank liner of the solar water heater with the above structure is butt-welded by the head of the stainless steel pressurized water tank liner, and the head is welded into a heat exchanger built into the water tank liner, so that the water tank cavity is artificially divided into three parts: cold water, warm water and hot water. There are three compartments, and guide pipes are installed on the upper walls of the three compartments to guide the water flow into an S-shaped flow direction, and the water is guided into different compartments according to the temperature, so that the heating and heat storage are integrated. Since the separation of the chambers becomes smaller and the temperature of the three chambers increases progressively, the water area with the highest temperature will always be concentrated in the compartment for direct hot water supply, which is convenient for water. In addition, such a structure has a built-in heat exchanger, which reduces the capacity of the heat exchange medium and improves the heat exchange efficiency.

Detailed ways

As shown in Figure 1, the water tank liner 1 is butt-welded by the stainless steel pressurized water tank liner head 2, and the head is welded into a heat exchanger 3, and an exhaust pipe 6 is built in the heat exchanger 3. The exhaust pipe 6 The length of length will be slightly shorter than the length of heat exchanger 3, and such arrangement makes on water tank and heat exchanger 3 avoid opening too many holes because of exhaust. Then connect the stainless steel part of the head 2 as a component of the heat exchanger 3. At this time, its width can be adjusted according to the needs of the heat exchange area. The larger the heat exchange area, the larger the width should be. The size of the heated area. Then use non-metallic sealing material to seal the heat exchanger 3 and the water tank liner 1, and divide the water tank liner 1 into several cavities, generally divided into three cavities of cold water, warm water and hot water. 3. There are 4 guide tubes at the seal of the water tank liner 1, and the other end of the guide tube 4 hangs down to the bottom of the cavity, so that the water flow is in an S-shape, so that cold and hot water are isolated and reduce Mixture of hot and cold water. In addition, the upper circulation pipe 5 between the heat exchangers 3 in the water tank liner 1 is made T-shaped and connected to the medium tank. The medium hot water in the heat exchanger can circulate with each other and separate from the hot water in the water tank, because the heat exchanger part is operated without pressure and adopts the form of natural circulation, and the heat exchange medium can be water or Antifreeze, in the north where there is heating, it can even be passed through with heating.
