As shown in fig. 14, the heat exchange jacket 3 covers the cylindrical portion of the inner container 4, the hemispherical portions of the upper and lower ends of the inner container 4 are not covered by the heat exchange jacket 3, and the buffer sleeve 5 is disposed in the insulating layer 2. Specifically, the method comprises the following steps: the buffer sleeve 5 is arranged at the upper left corner in the heat-insulating layer 3.
The heat exchange jacket 3 is communicated with the buffer sleeve 5 through a connecting pipe 502, and the buffer sleeve 5 is provided with a vent 501 for communicating with the outside atmosphere. The connecting end of the connecting pipe 502 and the buffer sleeve 5 is arranged at the bottom end of the buffer sleeve 5, the connecting end of the connecting pipe 502 and the heat exchange jacket 3 is arranged at the top end of the heat exchange jacket 3,
The bottom of buffer sleeve 5 is located through the link with connecting pipe 502 and buffer sleeve 5, the top that heat transfer jacket 3 was located to the link that connecting pipe 502 and heat transfer jacket 3, can be when realizing the liquid seal that heat transfer jacket 3, reduce the quantity of medium in the medium circulation pipeline, because the in-process of pouring into the medium into toward the medium circulation pipeline, only after filling up the medium in heat transfer jacket 3, the medium just can get into in the connecting pipe 502, do not locate the top that heat transfer jacket 3 and the link that connecting pipe 502 and heat transfer jacket 3 and compare, the quantity of medium can be saved.
in addition, the connecting end of the connecting pipe 502 and the heat exchange jacket 3 is higher than the connecting end of the connecting pipe 502 and the buffer sleeve 5, and the air vent 501 of the buffer sleeve 5 is higher than the top end of the heat exchange jacket 3 by 2-5 cm. The connecting end of the connecting pipe 502 and the heat exchange jacket 3 is higher than the connecting end of the connecting pipe 502 and the buffer sleeve 5, so that the medium used in the medium circulation pipeline when the medium circulation pipeline is full of medium is the least, and the medium can flow into the connecting pipe 502 and the buffer sleeve 5 in sequence after the heat exchange jacket 3 is full of medium in the process of injecting the medium into the medium circulation pipeline.
Further, the buffer sleeve 5 is made of high-temperature-resistant plastic, and the box body is provided with an observation window 6 for observing the medium liquid level in the buffer sleeve 5, as shown by a dotted line in fig. 14.
when the high-temperature medium in the heat exchange jacket 3 expands, the expanded medium which is larger than the medium circulation pipeline flows into the buffer sleeve 5 from the top end of the heat exchange jacket 3 through the connecting pipe 502, the expansion pressure from the high-temperature medium borne by the medium circulation pipeline is released, and at the moment, the medium circulation pipeline still runs full of the medium; when the heat of the high-temperature medium in the heat exchange jacket 3 is absorbed by the low-temperature tap water in the inner container 4, the temperature of the high-temperature medium in the heat exchange jacket 3 is reduced to become a low-temperature medium, the volume of the low-temperature medium is reduced, the air pressure in the heat exchange jacket 3 is reduced, the medium entering the buffer sleeve 5 can enter the heat exchange jacket 3 again, and at the moment, the medium circulation pipeline still runs full of the medium. Therefore, the buffer sleeve 5 can release the pressure born by the medium circulation pipeline due to expansion caused by heat and contraction caused by cold of the medium, realize the non-bearing and full medium operation of the medium circulation pipeline, avoid the medium circulation pipeline from being broken due to stress fatigue, prolong the service life of the medium circulation pipeline, avoid the manpower and material resources consumed by maintaining and replacing the medium circulation pipeline, reduce the use cost of the medium circulation pipeline, avoid the paralysis of the medium circulation pipeline and ensure the normal use of the split solar water heater.
Although the above description has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and on the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative efforts are still within the scope of the present invention.
