[0001] The invention relates to the technical field of heat exchangers, and in particular to a multi-return rapid heating type electric boiler heat exchanger. Background Art

[0002] Energy storage electric boilers are usually designed with water and electricity separated. Heat exchange requires the exchange of high-temperature air and water, and generally has a large power, so the heat exchange power of the heat exchanger is also required to be relatively large. However, due to the influence of the site, the volume of the heat exchanger needs to be minimized, so multiple heat exchangers will be combined and spliced ​​to reduce heat dissipation while reducing the occupied area and volume.

[0003] Correspondingly, after multiple heat exchangers are combined, heat exchange will occur between the heat exchangers due to the close fit between the heat exchangers or the installation with a small gap between them, resulting in different degrees of impact on the medium temperature originally used in different scenarios, thereby causing deviations in the final derived medium temperature used in different scenarios.

DETAILED DESCRIPTION

[0024] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 5 As shown, the multi-return rapid heating electric boiler heat exchanger provided by the present invention comprises a heat exchanger body 1, a plurality of pipe connection ports 2 are provided on the outer side of the heat exchanger body 1 for water inlet and outlet, a heat exchange cavity 5 is provided on the inner side of the heat exchanger body 1, connection ribs 3 are fixed on both the left and right sides of the heat exchanger body 1, and a hole structure is provided on the inner side of the connection rib 3, and a gap adjustment mechanism 4 is correspondingly installed in the hole structure on the inner side of the connection rib 3 to control the degree of fit between the monomers of the heat exchanger body 1, wherein:

[0026] like Figure 2 As shown, the gap adjustment mechanism 4 includes a positioning plate 401, a mounting column 402 is fixed on one side of the positioning plate 401 close to the connecting rib plate 3, and the mounting column 402 penetrates the hole structure of the connecting rib plate 3, a connecting seat 403 is installed on the outer side of the mounting column 402, and a connecting plate 404 is fixed on one end of the connecting seat 403 away from the mounting column 402, and a plurality of adjustment bolts 405 are installed on the inner side of the connecting plate 404, and the adjustment bolts 405 penetrate the hole structure provided on the inner side of the positioning plate 401 on the adjacent side, and are threadedly connected with the connecting rib plate 3;

[0027] Specifically, after the monomers of the heat exchanger body 1 are fitted together, the adjusting bolt 405 is rotated to increase the installation depth of the adjusting bolt 405 in the connecting rib 3, so that the distance between the connecting plate 404 and the connecting rib 3 where the adjusting bolt 405 is installed is reduced, so that the connecting rib 3 monomer at the installation position of the positioning plate 401 is driven to move closer to the connecting rib 3 monomer at the installation position of the adjusting bolt 405, thereby increasing the fit between the adjacent heat exchanger body 1 monomers, reducing the gas flow inside, and increasing the heat exchange efficiency between the adjacent heat exchanger body 1 monomers;

[0028] After the heat exchanger body 1 is assembled, the several pipe connection ports 2 arranged on the outside thereof will discharge the water to different usage scenarios, resulting in the need for water of corresponding temperatures in different usage scenarios, and the adjacent heat exchanger bodies 1 will exchange heat, resulting in the same temperature of the water discharged in all scenarios. Therefore, in the assembly composed of the heat exchanger body 1 monomers, it is best that different heat exchanger bodies 1 can achieve different temperatures of heat conduction and heat exchange efficiency;

[0029] In the assembly of the heat exchanger body 1, the gap adjustment mechanism 4 is used to adjust the distance between the monomers of the heat exchanger body 1, so that heat exchange cannot occur between adjacent heat exchanger bodies 1 or the heat exchange efficiency is reduced, thereby avoiding the same temperature water output between adjacent heat exchanger bodies 1, and the gap adjustment mechanism 4 is installed on the outside of the heat exchanger body 1, so that adjacent heat exchanger bodies 1 can be combined, thereby adjusting the water supply rate required in the current usage scenario according to actual needs.

[0030] The inner side of the connecting seat 403 is hollow, and the connecting seat 403 and the mounting column 402 form a sliding connection. A limit spring 406 is arranged on the inner side of the connecting seat 403, and the limit spring 406 is installed on the outer side of the mounting column 402. The longitudinal section of the mounting column 402 is "T"-shaped, so that the connecting seat 403 forms an elastic connection with the mounting column 402 by means of the limit spring 406. When sliding occurs between the connecting seat 403 and the mounting column 402, the limit spring 406 is deformed, so that the limit spring 406 can be used to make the monomers of the heat exchanger body 1 fit more closely, and can also make the threaded connection between the adjusting bolt 405 and the connecting rib 3 tighter, thereby reducing the possibility of loosening.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, a heat exchange control mechanism 6 is further provided at the gap between the monomers of the heat exchanger body 1 to regulate the heat exchange or heat insulation between adjacent heat exchanger bodies 1, wherein the heat exchange control mechanism 6 includes a filling capsule 601, the inner side of the filling capsule 601 is hollow, the filling capsule 601 and the groove structure provided on the outer side of the heat exchanger body 1 are fitted, and a heat preservation film 603 is installed at one end of the filling capsule 601, and a plurality of connecting pipes 602 are installed on one side of the heat preservation film 603, so that the connecting pipe 602 has multiple inlets and outlets when being introduced or exported, and is also convenient for exhaust, and a pipeline structure is provided on the inner side of the connecting pipe 602 to communicate with the inner side of the filling capsule 601;

[0032] Specifically, when the heat exchanger body 1 is produced, a certain groove structure will inevitably be processed on the outer surface of the heat exchanger body 1. Such groove structure has the function of strengthening the strength of the heat exchanger body 1, but the existence of such groove structure will affect the heat exchange efficiency between adjacent heat exchanger bodies 1 to a certain extent, and even if the outer surface of the heat exchanger body 1 is processed flat, the surface of the heat exchanger body 1 will be affected by the thermal expansion and contraction of the material and certain cavities will appear. Therefore, when heat exchange is required between adjacent heat exchanger body 1 monomers, heat transfer oil is introduced from the connecting pipe 602. After the heat transfer oil is introduced, the connecting pipe 602 can make the filling capsule 601 fit the groove structure on the outer surface of the heat exchanger body 1 and continue to fill the pits that may exist on the outer surface of the heat exchanger body 1, thereby increasing the heat exchange efficiency between adjacent heat exchanger body 1 monomers. Finally, the adjusting bolt 405 is rotated to make the corresponding heat exchanger body 1 monomers fit together, thereby closing the inlet and outlet of the connecting pipe 602.

[0033] When heat exchange is not required between adjacent heat exchanger bodies 1, a safe gas with low thermal conductivity such as carbon dioxide is introduced into the filling capsule 601 for heat insulation;

[0034] A positioning piece 604 corresponding to the connecting rib 3 is installed on the outer side of the filling capsule 601, and a hole structure corresponding to the connecting seat 403 is opened on the inner side of the positioning piece 604, so as to facilitate the positioning of the filling capsule 601. At the same time, the positioning piece 604 is used to block the parts that may form a cold bridge between adjacent heat exchanger bodies 1 to avoid the occurrence of a cold bridge phenomenon.
