A kind of fluid heater, the heating component that include pipeline for the transporting fluid, is used for the water back inner fluid be connected assembled conduit and be connected the connection shell with heating component, be formed with the first through hole and the second through hole on this connection shell, this heating component and pipeline are embedded at respectively in the first through hole, the second through hole; This heating component includes heating wire, metal inner pipe and metal outer pipe; Wherein, this heating wire is positioned at metal inner pipe inside, is filled with the first insulated enclosure layer between this heating wire and the metal inner pipe; This metal outer pipe is placed in the metal inner pipe periphery, and is filled with the second insulated enclosure layer between this metal outer pipe and the metal inner pipe.

As a kind of preferred version, offer the opening slot that arranges along the hole bearing of trend on the outer wall of described the first through hole, this opening slot is communicated in the first through hole and is connected the shell outside.

As a kind of preferred version, described connection shell is aluminium mass shell body.

As a kind of preferred version, described the first through hole outer wall is cirque structure.

As a kind of preferred version, described heating wire two ends are electrically connected with respectively draws rod, and this draws, and an excellent end is positioned at metal inner pipe inside and its other end stretches out outside, metal inner pipe end, and opening part is packaged with sealed insulation glue in the both ends of metal inner pipe.

As a kind of preferred version, the both ends opening part of described metal outer pipe is packaged with sealed insulation glue.

As a kind of preferred version, described the first insulated enclosure layer and the second insulated enclosure layer are filled by magnesia powder and are formed.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, it mainly is to be provided with metal inner pipe, metal outer pipe by the heating wire outer race in heating power, and in filling the insulated enclosure material between heating wire and the metal inner pipe, between metal inner pipe and the metal outer pipe, so form heating component; This heating component homogeneous heating, the setting of metal inner pipe and metal outer pipe have also improved heat conduction velocity greatly, Effective Raise its firing rate to the pipeline inner fluid, this fluid heater has better heating properties.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
