Embodiment
Shown in Fig. 1 and 2 is a kind of aluminium alloy heating tube by thick-film heating that is applied in the foot bath, comprise, the heating tube main body of cylindrical aluminum alloy material, thick-film heating plate, heating tube shell, silica gel lead directly to and the silica gel threeway, it is characterized in that, the side of described heating tube main body is provided with the radially inside insertion groove of a depth direction, the severity control of insertion groove is in the 70%-85% of heating tube diameter, and described thick-film heating plate is inserted in this insertion groove.Be provided with a pair of clamping section in insertion groove import department on the heating tube main body, be provided with 3 location holes on the clamping section, evenly distributed, with special-purpose machinery it is clamped first between the clamping section, with screw and nut locking, heating tube main body and thick-film heating plate are fixed together firmly afterwards.Described heating tube main body be respectively equipped with in the both sides (both sides of Width) of insertion groove length direction along the heating tube body shaft to the through hole (the outer setting of semicircular circular arc portion) of approximate half-circular.Vertically be provided with 3 ribs on the described semicircular planar section and be evenly arranged middle rib summary length along the insertion groove depth direction.The surface of described planar section and rib is ups and downs corrugated surface (such as Fig. 3), and is uneven, can increase the contact area of water and heating tube main body inner wall, makes heat-transfer rate faster.
Described heating tube shell is the cylindrical shell of a both ends open, and heater body is installed in the heating tube shell, because the heating tube casing is in heater body outside, so that heating tube integral body appearance looks elegant not only, and heat is difficult for scattering and disappearing.One end of heater body is fixedly connected with by the snap close ring with silica gel is straight-through, and its other end is fixedly connected with by the snap close ring with the silica gel threeway, and the two ends of insertion groove seal with silica gel plug respectively.Silica gel straight-through with silica gel threeway be connected and be connected with outside water supply or water outlet equipment.A temp control switch is installed in the side of heating tube main body, be used for the temperature that the heating of control heating tube reaches, in the silica gel threeway of assembling with it in the heating tube end, a temperature sensor is installed, is used for the temperature of water in the heating tube is passed to control chip.
The tangible stainless steel substrate of described thick-film heating plate is enclosed first one deck insulating heat-conductive coating, then, and by silk-screen printing technique printed circuit layer on this insulating heat-conductive coating; Then, on the circuit layer that produces, be coated with again one deck insulating heat-conductive coating; At last, high temperature sintering forms.The thick-film heating plate is higher than the utilance of traditional mode of heating heat, reaches 70 ~ 95%, and energy-conserving and environment-protective are favored by the client more.
During use, start water inlet system, current enter heating tube main body (simultaneously, the thick-film heating plate begins heating) by the silica gel threeway, and to flow to silica gel along through hole straight-through always, reaches to the outside.Current are flowed through during the through hole, the thick-film heating plate with electric energy conversion be thermal energy transfer to the heating tube main body, thereby the current that flow through are heated rapidly.Be not difficult to find out that the thick-film heating plate is arranged on the outside of heating tube main body, its working method is indirectly with the current in the heat transferred pipe by the heat conduction.The thick-film heating plate is to print insulating medium layer at corrosion resistant plate, be printed with alloy material layer at insulating medium layer, thick-film resistor and other conductor materials are to be printed on the alloy material layer, and then on thick film circuit, print respectively again one deck alloy material layer and insulating medium layer, therefore the current-carrying part on the thick-film heating plate is kept apart with regard to being insulated material fully, the outer surface of whole plate just all insulate, heating tube does not just have the situation generation of electric leakage like this, has greatly improved the coefficient of safety of equipment.
In order further to improve the insulation property by the aluminium alloy heating tube of thick-film heating, during installation, be lined with two cloudlet master slices at the outer surface of thick-film heating plate, make the insulating properties of heating tube many again one protecting wall, safe and reliable.
Below only expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement; these all belong to protection range of the present utility model; and the utility model not only is applied in the middle of the foot bath, can also relate in the middle of other heating systems.Therefore, the protection range of the utility model patent should be as the criterion with claims.
