Abstract
The utility model discloses a kind of electric heater, comprise the housing being provided with cavity, the two ends of housing are respectively equipped with fluid intake and fluid issuing, be interval with at least one heater block and at least one disturbing flow device in the cavity of housing successively, external fluid enters from fluid intake and flows out from fluid issuing after heater block and disturbing flow device.Its advantage produces flow-disturbing after the fluid after heating runs into disturbing flow device, inhibits the formation of heater block nearby layers laminar boundary layer, improve heat exchange efficiency; Because the flow-disturbing wheel of adjacent disturbing flow device is orthogonal, under the stirring action of disturbing flow device, be evenly distributed by the fluid temperature (F.T.) heated in housing, thus avoid heater block surface localized hyperthermia, extend the service life of heater block.
Description
Technical field
The utility model relates to heater context, especially a kind of electric heater.
Background technology
There is the various electric heater that fluid is heated in the market, the heater block of electric heater inside, in order to reach better heating effect to fluid, is arranged to vertical with runner (namely heater block is vertical with fluid flow direction) by these electric heaters.The part but this setup comes with some shortcomings, as well-regulatedly in heater block to be evenly arranged in electric heater, fluid easily forms stable fluidised form when heater block, thicker laminar boundary layer is formed near heater block, reduce the efficiency of heating surface, hand over mixed more weak simultaneously between fluid, make fluid temperature (F.T.) skewness.
Summary of the invention
The purpose of this utility model solves the deficiencies in the prior art, provides a kind of electric heater.
The technical solution of the utility model:
A kind of electric heater, comprise the housing being provided with cavity, the two ends of housing are respectively equipped with fluid intake and fluid issuing, be interval with at least one heater block and at least one disturbing flow device in the cavity of housing successively, external fluid enters from fluid intake and flows out from fluid issuing after heater block and disturbing flow device.
A kind of preferred version is the quantity of heater block is 2 ~ 8, and the quantity of disturbing flow device is corresponding with the quantity of heater block.
A kind of preferred version is the quantity of heater block is 7, the quantity 3 of flow-disturbing dress.
Preferred version is that disturbing flow device comprises the framework being fixed on inner walls, to be located at inside framework and the some support bars be parallel to each other and the flow-disturbing wheel be located between support bar.
A kind of preferred version is that flow-disturbing wheel comprises matrix and is located at the blade of matrix surrounding.
Preferred version is that disturbing flow device also comprises the fixed axis be vertical on support bar, and fixed axis is divided into some sections by support bar and every section of fixed axis is provided with a flow-disturbing takes turns, and flow-disturbing wheel freely rotates around fixed axis.
A kind of preferred version is that the flow-disturbing wheel of adjacent two disturbing flow devices is orthogonal.
A kind of preferred version is that heater block is formed by some U-shaped heating tube series connection.
A kind of preferred version is the profile of heater block is S shape.
A kind of preferred version is the profile of heater block is three-back-shaped.
Technique scheme has following beneficial effect: fluid enters from fluid intake, heat through heater block, the fluid after heating produces flow-disturbing after running into disturbing flow device, and the flow direction of fluid changes, inhibit the formation of heater block nearby layers laminar boundary layer, improve heat exchange efficiency; Because the flow-disturbing wheel of adjacent disturbing flow device is orthogonal, under the stirring action of disturbing flow device, be evenly distributed by the fluid temperature (F.T.) heated in housing, thus avoid heater block surface localized hyperthermia, extend the service life of heater block.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the stereogram of the utility model middle shell;
Fig. 3 is the stereogram of disturbing flow device in the utility model;
Fig. 4 is the schematic diagram of heater block in the utility model.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 4, a kind of electric heater, comprise the housing 1 being provided with cavity, the two ends of housing 1 are respectively equipped with fluid intake 2 and fluid issuing 4, be interval with at least one heater block 3 and at least one disturbing flow device 5 in the cavity of housing 1 successively, external fluid enters from fluid intake 2 and flows out from fluid issuing 4 after heater block 3 and disturbing flow device 5.
Fluid enters from fluid intake 2, heats through heater block 3, and the fluid after heating produces flow-disturbing after running into disturbing flow device 5, and the flow direction of fluid changes, and inhibits the formation of heater block 3 nearby layers laminar boundary layer, improves heat exchange efficiency; Disturbing flow device 5 is also even by fluid agitation simultaneously, makes to be evenly distributed by the fluid temperature (F.T.) heated in housing, thus avoids the surperficial localized hyperthermia of heater block 3, extends the service life of heater block 3.
The quantity of heater block 3 is 2 ~ 8, and the quantity of disturbing flow device 5 is corresponding with the quantity of heater block 3.The quantity that in the present embodiment, heater block is put is 7, the quantity 3 of flow-disturbing dress.Certainly, in some other embodiment, the quantity of heater block 3 and the quantity of disturbing flow device 5 can choose other number.Wherein, disturbing flow device 5 comprises the framework 51 being fixed on housing 1 inwall, to be located at inside framework 51 and the some support bars 52 be parallel to each other and the flow-disturbing wheel 53 be located between support bar 52.Disturbing flow device 5 also comprises the fixed axis be vertical on support bar 52, and fixed axis is divided into some sections by support bar 52 and every section of fixed axis is provided with a flow-disturbing wheel 53, and flow-disturbing wheel 53 freely rotates around fixed axis.Flow-disturbing wheel 53 comprises matrix and is located at the blade of matrix surrounding, and matrix is preferably cylinder, and blade is evenly arranged along cylinder.In order to better realize the purpose of this utility model, wherein, in housing 1, the flow-disturbing of adjacent two disturbing flow devices 5 is taken turns 53 orthogonal, and namely the installation direction of disturbing flow device 5 is mutually vertical, and heater block 3 is connected by some U-shaped heating tubes and formed.
In other embodiments, the profile of heater block is the profile of S shape or heater block is three-back-shaped.
It is more than detailed description of the invention of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
