Description

Technical Field

[0001] The utility model relates to the technical field of RV water heaters, and particularly to a hot water generating device for RVs. Background Art

[0002] As a special vehicle integrating living and traveling functions, the internal design of an RV often needs to consider various living needs of occupants during the journey. Among them, hot water is an indispensable part. To heat the water in the RV water tank into hot water, a hot water generating device for RVs is required.

[0003] Some current hot water generating devices for RVs on the market: For example, the utility model patent with the authorization announcement number CN221137966U discloses a multifunctional hot water tank for RVs. This device can use a fuel heater to heat the antifreeze, making the heated antifreeze flow through the first heat exchange tube and then return to the first antifreeze kettle. During this process, the antifreeze in the first heat exchange tube exchanges heat with the fresh water in the water heater. The antifreeze passing through the RV engine is pumped into the second heat exchange tube through a booster pump and then returns to the second antifreeze kettle. During this process, the heated antifreeze in the second heat exchange tube exchanges heat with the fresh water in the water heater. However, since the first and second heat exchange tubes for heat exchange are tubular structures, the surface area in contact for heat exchange is small, resulting in an unsatisfactory heat exchange effect and room for improvement.

[0004] Therefore, we propose a hot water generating device for RVs to solve the problems mentioned above. Content of the Utility Model
