Problems solved by technology

[0004] This existing technology has the following problems: on the one hand, considering the phenomenon of the medium’s thermal expansion and cold contraction, the medium circulation pipeline cannot run with a full medium, and there is a part of air in the medium circulation pipeline in addition to the presence of the medium, and the medium The hot and humid air in the circulation pipeline will aggravate the corrosion of the medium circulation pipeline and cause the leakage of the medium circulation pipeline; on the other hand, the medium in the medium circulation pipeline is fully enclosed, and the medium circulation pipeline will expand due to the volume If the expansion pressure cannot be effectively released, the non-pressure operation of the medium circulation pipeline cannot be realized, and it is easy to cause the medium circulation pipeline to rupture due to stress fatigue
[0005] Therefore, the above two problems will not only shorten the service life of the medium circulation pipeline, increase the use cost of the medium circulation pipeline, but also cause the paralysis of the medium circulation pipeline, affecting the normal use of the split solar water heater

Embodiment 1

[0044] Such as Figure 1-4 As shown, a non-pressurized split solar water heater with full medium operation includes a horizontal solar water tank, and the horizontal solar water tank includes a tank, a heat exchange jacket 3 , an inner tank 4 , and a buffer sleeve 5 . The box body includes an outer shell 1 and an insulating layer 2 arranged coaxially from the outside to the inside. The box body, the heat exchange jacket 3, and the liner 4 are coaxially arranged in sequence from the outside to the inside, and the heat exchange jacket 3 communicates with the heat collector 8 to form a closed medium circulation pipeline, specifically: the heat exchange jacket 3 passes through the medium The inlet pipe 9 and the medium outlet pipe 10 communicate with the heat collector 8 to form a closed medium circulation pipeline.

[0045] Such as image 3 As shown, the heat exchange jacket 3 only wraps two-thirds of the inner tank 4, and the heat exchange jacket 3 wraps the lower half of the ...

Embodiment 2

[0056] This embodiment 2 is the same as embodiment 1, the difference is that, as Figure 6 and Figure 7 As shown, the water tank is a vertical solar water tank, and the heat exchange jacket 3 wraps half to all of the inner tank 4. In this embodiment 2, the heat exchange jacket 3 wraps the middle and lower parts of the inner tank 4, and the buffer sleeve 5 Set above the heat exchange jacket 3, that is, the buffer sleeve 5 is set at the place where the inner tank 3 is not wrapped by the heat exchange jacket 3, specifically: as Figure 7 As shown, the buffer sleeve 5 is in the shape of a ring cylinder.

Embodiment 3

[0058] This embodiment 3 is the same as embodiment 2, the difference is that, as Figure 8 and Figure 9 As shown, the heat exchange jacket 3 wraps the cylindrical part of the inner tank 4 , the upper and lower hemispherical parts of the inner tank 4 are not wrapped by the heat exchange jacket 3 , and the buffer sleeve 5 is arranged in the insulation layer 2 . Specifically: such as Figure 8 As shown, the buffer sleeve 5 is arranged in the upper left corner of the thermal insulation layer 3. Of course, the buffer sleeve 5 can also be arranged in the upper right corner of the thermal insulation layer 2. The height of the connecting end of the buffer jacket 5 is even, and the connecting end of the connecting pipe 502 and the heat exchanging jacket 3 is arranged on the upper end of the heat exchanging jacket 3 .

[0059] By arranging the buffer sleeve 5 in the thermal insulation layer 2, not only the area of ​​the inner tank 4 wrapped by the heat exchange jacket 3 can be enlarg...

Abstract

The invention discloses a non-bearing and full-medium-operated split type solar water heater, and relates to the technical field of split type solar water heaters. A water tank comprises a tank body,a heat exchange jacket and an inner container sequentially arranged from outside to inside; the heat exchange jacket communicates with a heat collector so as to form a medium circulation pipeline; a medium is fully filled in the medium circulation pipeline; the heat exchange jacket communicates with a buffer sleeve through a connecting pipe; the buffer sleeve is provided with a vent hole communicating with the outside atmosphere; the connecting end of the connecting pipe and the buffer sleeve is arranged at the lower end of the buffer sleeve, and the vent hole of the buffer sleeve is higher than the top end of the heat exchange jacket; or the connecting end of the connecting pipe and the buffer sleeve is arranged at the lower end of the buffer sleeve, and the connecting end of the connecting pipe and the heat exchange jacket is arranged at the upper end of the heat exchanger jacket. According to the non-bearing and full-medium-operated split type solar water heater provided by the invention, non-bearing and full-medium operation can be realized, the service life of the medium circulation pipeline is prolonged, the use cost of the medium circulation pipeline is reduced, the failureof the medium circulation pipeline is avoided, and the split type solar water heater can be used normally.

Description

technical field [0001] The invention relates to the technical field of split-type solar water heaters, in particular to a split-type solar water heater operating without pressure and full of medium. Background technique [0002] Solar water heaters include compact solar water heaters and split solar water heaters. Among them, the split solar water heater separates the water tank from the heat collector to increase the capacity of the water tank. Split solar water heaters are widely used. [0003] In the prior art, the water tank of the split-type solar water heater includes a tank body, a heat exchange jacket, and an inner tank arranged in sequence from outside to inside, and the heat exchange jacket communicates with the heat collector to form a medium circulation pipeline. [0004] This existing technology has the following problems: on the one hand, considering the phenomenon of the medium’s thermal expansion and cold contraction, the medium circulation pipeline cannot r...
