Description

A three-compartment solar water heater pressurized water tank

technical field

The utility model relates to the field of solar water heaters, in particular to a pressurized water tank of a three-chamber solar water heater.

Background technique

The water tank of the existing pressurized solar water heater generally has the entire water tank as a pressurized water tank, and the vacuum tube adopts a superconductor for heat transfer, which has a high cost, and the heat transfer in the vacuum tube is indirect, and the efficiency is low.

Contents of the invention

The technical problem to be solved by the utility model is to propose a low-cost, high-efficiency three-chamber solar water heater pressurized water tank.

In order to solve the above-mentioned technical problems, a pressurized water tank of a three-chamber solar water heater of the utility model includes a cold water tank, a heating cabin, a hot water tank and a heat exchange tube, the cold water tank and the hot water tank are independent pressure tanks, and the The heating cabin is a non-pressurized cabin, the left side of the cold water cabin is fixedly connected to the heating cabin, the right side of the heating cabin is fixedly connected to the hot water cabin, and a plurality of heat exchange tubes pass through the cold water cabin. From the heating cabin to the hot water cabin, the two ends of the heat exchange tubes are fixedly connected to the bulkheads of the cold water tank and the hot water tank respectively, and communicate with the cold water tank and the hot water tank.

In the above-mentioned three-compartment solar water heater pressurized water tank, the left side of the cold water compartment and the heating compartment are welded and fixed by the left disc-shaped head, and the right side of the heating compartment and the hot water compartment are fixed by the right disc The two ends of each heat exchange tube are respectively fixedly connected with the left dished head and the right dished head by welding.

In the pressure-bearing water tank of the above-mentioned three-chamber solar water heater, the heat exchange tubes are stainless steel heat exchange tubes.

Because the utility model adopts the above-mentioned technical scheme, when installing, the all-glass vacuum heat collecting tube is inserted into the heating cabin, and the vacuum heat collecting tube converts light energy into heat energy, and the water in the vacuum heat collecting tube is heated and repeated with the water in the heating cabin. Natural circulation, so that the water in the heating chamber is heated. At this time, as long as the hot water switch is turned on, the cold water will pass through the heat exchange stainless steel tubes placed in the heating cabin from the pressurized cold water tank due to the pressure of the tap water, and exchange heat with the hot water in the heating cabin, thus turning into hot water. The water enters the pressurized hot water tank on the right, and is sent to the homes of users who need hot water by using the pressure of tap water. The utility model adopts the combination of the pressurized cabins at the two ends and the non-pressurized cabin in the middle, finally realizes the pressure-bearing operation of the system, reduces the cost and improves the efficiency. At the same time, the hot water provided to users is also cleaner.

Detailed ways

As shown in Figure 1, the pressurized water tank of the three-compartment solar water heater includes a cold water tank 1, a heating tank 2, a hot water tank 3 and a heat exchange stainless steel tube 6. The cold water tank 1 and the hot water tank 3 are independent pressure tanks, and the heating tank 2 is a non-pressurized cabin, on which there is a socket 7 of an all-glass vacuum heat collecting tube. The cold water cabin 1 and the heating cabin 2 are fixedly connected by welding the dish-shaped head 4 on the left side, and the heating cabin 2 and the hot water cabin 3 are connected through the right side. The dished head 5 is welded and connected (please also refer to Figure 2). As shown in FIG. 3 and FIG. 4 , through holes 8 are provided on the left dished head 4 and the right dished head 5 . As shown in Figure 1, a plurality of heat exchange stainless steel tubes 6 pass through the heating cabin 2 from the cold water tank 1 to the hot water tank 3, and are respectively connected with the left dished head 4 and the right dished head 5 in the through hole 8 connected by welding. Both ends of each heat exchange stainless steel tube 6 communicate with the cold water tank 1 and the hot water tank 2 respectively.

The water tank of the utility model is matched with the all-glass vacuum heat-collecting tube of the solar water heater, and the outer wall of the all-glass vacuum heat-collecting tube is coated with a spectral selective absorption coating to absorb sunlight. Its working principle is as follows: the vacuum heat collecting tube absorbs the radiation of sunlight, the solar energy is converted into heat energy, and the water in the vacuum heat collecting tube is heated. The temperature keeps rising. When the user uses hot water, the tap water uses its own pressure to enter the pressurized cold water tank through the left water pipe, and then enters multiple heat exchange stainless steel pipes from the cold water tank. When the cold water passes through the stainless steel pipe, it will exchange heat with the hot water in the heating chamber, then enter the pressurized hot water chamber, and reach the user's place of use from the outlet pipe.
