technical field

The utility model relates to the field of solar energy devices, in particular to a gradient heating type solar water storage tank.

Background technique

In today's advocacy of energy saving and environmental protection, solar water heaters are more and more used in daily life. The basic working principle of solar water heaters is to absorb the thermal energy of the solar collector device through a heat conducting medium, and heat the water tank by means of a medium conduit by means of heat conduction. At present, the solar hot water storage tank adopts an integral water tank, that is, the inside of the water tank is an integral cavity, and it takes a long time for the heat transfer medium to heat the water in the entire water tank, especially in areas with insufficient sunlight. . At present, many solar water heaters have built-in electric heaters in the water tank. In the event of insufficient hot water supply or insufficient sunlight, the electric heater will be activated to heat the water in the water tank, but the water in the entire water tank should be heated to The time and electricity required for a certain temperature are still a lot, and people's domestic water often does not need the water in the entire water tank, so a lot of heat will be lost invisibly due to non-use.

Detailed ways

As shown in FIG. 1 to FIG. 3 , the gradient heating type solar water storage tank of the present invention includes a heat storage barrel 1 and a medium conduit 2 arranged in the heat storage barrel 1 . An insulating layer is arranged on the outside of the wall; the interior of the heat storage barrel 1 also includes a heat insulation board 7 that divides the inner cavity of the heat storage barrel 1 into a number of closed water tank partitions 10, and the medium conduit 2 extends from the left side of the heat storage barrel 1. The low position obliquely passes through the heat insulating plate 7 inside the heat storage barrel 1, and protrudes from a higher position on the right side of the heat storage barrel 1; the upper end of the heat insulating plate 7 is fixedly connected with a communication conduit 6, and the communication conduit 6 The two adjacent water tank partitions 10 on the left and right are connected, and one end of the communication conduit 6 extends into the upper part of the water tank partition 10 on the left side of the thermal insulation board 7 , and the other end extends into the bottom of the water tank partition 10 on the right side of the thermal insulation board 7 .

A cold water inlet 8 is arranged on the left side of the heat storage tank 1, and a hot water outlet 4 is arranged on the right side.

A heat exchange medium inlet 9 is provided on the left side of the heat storage barrel 1, and a heat exchange medium outlet 3 is provided on the right side.

An electric heater 5 is arranged in the rightmost water tank partition 10 in the heat storage barrel 1 .

The communication conduit 6 is 7-shaped, the upper end of the communication conduit 6 extends into the upper part of the water tank partition 10 on the left side of the heat insulation plate 7 , and the lower end of the communication conduit 6 extends into the bottom of the water tank partition 10 on the right side of the heat insulation plate 7 .

A circulating pump can be configured on the pipeline of the medium conduit 2 to promote the heat conduction medium in the pipeline to flow and conduct heat, so as to improve the thermal conduction efficiency. The medium conduit 2 can also be arranged in a structure parallel to the central axis of the heat storage tank 1, which is simple in structure, but a circulating pump must be configured to do a forced circulation to meet efficient heat conduction.

Each water tank partition 10 divided by the heat insulation board 7 is an independent heat storage space, and the water tank partitions 10 adjacent to each other realize the circulation of water flow through the communication conduit 6, and the heat transfer medium is used to heat the water in the water tank. The principle of the middle hot water layer is always at the top of the water level, the hot water layer is above the left water tank partition 10, and the hot water in the hot water layer flows to the right water tank partition 10 through the communication conduit 6, and finally forms a right side of the water tank partition. The water temperature in the water tank partition 10 on the left side is higher than the overall temperature of the water temperature in the water tank partition 10 on the left side, so that the entire internal space of the water tank is divided into several water tank partitions 10 with different temperatures. The higher temperature water tank partition 10 takes water, and only heats the water in the rightmost water tank partition 10 during electric heating, so that the water user can quickly use hot water.

The structure of the utility model is especially suitable for areas with short illumination time and insufficient illumination. This area needs to heat the water in the water tank within a limited time, but often due to insufficient sunlight and insufficient time, the water temperature of a whole tank of water cannot reach When it comes to the usage requirements, when the electric heater 5 is used for heating, the hot water is often wasted because a whole tank of hot water cannot be used. The utility model completely solves the technical problem from the structure of the water tank, and in a short time, the limited heat is transmitted to the rightmost water tank partition 10 step by step through the heat transfer inside the water tank, and because the heat insulation plate 7 and the communication conduit With the special design of 6, the heat transfer process from right to left cannot be realized, so the limited heat can be collected as much as possible in the rightmost water tank partition 10, so as to meet the needs of water users.
