In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings used in the description of the embodiments will be briefly introduced below. It is obvious that the drawings in the following description are only examples or embodiments of the application, from which the application can also be applied to other similar scenarios without inventive effort for a person skilled in the art. Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.

As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that these steps and elements do not form an exclusive list, and that an apparatus may comprise other steps or elements.

FIG. 1 is a schematic view of a heat exchanger shown according to some embodiments of the present application. As shown in FIG. 1, the heat exchanger comprises an S-shaped sleeve arranged by the upper and lower fall. The S-jacket is used for heat exchange between at least two fluids. In some embodiments, the inside of the sigmoid sleeve comprises at least a first and a second passage for the flow of a first and a second fluid, respectively, inside said sigmoid sleeve. Wherein the first fluid enters from the lower port 101 of the S-shaped sleeve and exits from the upper port 102 of the S-shaped sleeve; the second fluid enters through the upper port 103 of the S-shaped sleeve and exits through the lower port 104 of the S-shaped sleeve.

In some embodiments, the first fluid may be a low temperature medium to be heated and the second fluid may be a high temperature heat transfer medium. Furthermore, the first fluid and the second fluid each comprise a medium of gas, liquid and a mixture of gas and liquid. In the actual use process, the first fluid can be domestic water with lower temperature to be used by a user, and needs to be heated by the heat exchanger to meet the requirement of the domestic water. The second fluid may be a high temperature medium for heat transfer, such as a high temperature gas, liquid, or gas-liquid mixture, depending on the type of heat source (e.g., air or water source) of the heat exchanger.

In some embodiments, when the water heater is not in operation and is in a low-temperature environment, because the vertical fall of the heat exchanger is large, the second fluid (water) is discharged out of the sleeve pipe only by opening the valve at the lower port through the gravity effect, and the problem that the water heater is frozen to be damaged at the low-environment temperature is solved.

Fig. 2 is a transverse cross-sectional view of a heat exchanger according to some embodiments of the present application. As shown in fig. 2, the S-shaped casing of the heat exchanger comprises a first channel (1), a second channel (2), a spiral intermediate heat transfer conduit (3) and an outer conduit (4). Wherein the first and second passages are separated from each other by a spiral intermediate heat transfer conduit. And the inner cavity surrounded by the spiral middle heat transfer pipeline (3) is a first channel (1), and the outer cavity surrounded by the spiral middle heat transfer pipeline (3) and the outer pipeline (4) is a second channel (2).

In some embodiments, the outer pipe (4) may be designed by using plastic material or steel material, the thickness may be designed to be in the range of 0.3-10.0mm, and the shape may be in a round/square structure mode. The spiral middle heat transfer pipeline (3) can be made of steel or copper, the thickness can be designed to be 0.2-5.0mm, and the outer wall of the spiral middle heat transfer pipeline is provided with a plurality of fins side by side.

FIG. 3 is a longitudinal cross-sectional view of a heat exchanger shown according to some embodiments of the present application. As shown in fig. 3, a first fluid (i.e., a low-temperature medium to be heated, such as water) flows through a first passage at the inside in the S-shaped sleeve; a second fluid (i.e., a high temperature heat transfer medium) flows through a second passage located outside in the S-shaped sleeve. The arrangement mode can ensure that the medium to be heated at low temperature can be surrounded by the heat transfer medium at high temperature and is heated uniformly.

The utility model relates to a heat exchanger has simple structure, save material, processing convenience, low in manufacturing cost, heat exchange efficiency height, energy consumption low grade advantage. In addition, the double-pipe heat exchanger with the S-shaped structure mode has large vertical fall and very clean water drainage, and the S-shaped structure mode is similar to a plate structure and is convenient to mount and dismount, so that the failure rate and the repair rate of the unit are reduced.
