Abstract

The utility model provides an electrothermal film liquid heater belonging to physical field electrical parts, which is characterized in that: the inner and outer casings are concentrically assembled and are sealed by two sealing plates to form a heating cavity. One sealing plate is provided with a liquid inlet pipe, the other sealing plate is provided with a liquid outlet pipe. The exterior margins of the inner and outer casings are connected with heat exchange vanes and form a flow channel with the liquid inlet pipe and the liquid outlet pipe. The inner wall of the inner casing is coated with an insulation heat conduction layer, an electrothermal film layer is coated on the insulation heat conduction layer, two ends of the electrothermal film is provided with terminals connected with power wires. The utility model can ensure the non-conducting connection of heater and heating medium and is disposed in the container, so the heater has no open fire and overcomes the danger of electric leakage. The heat exchange vane arranged on the inner casing not only forms a flow channel, but also increases the heat exchange area, so the utility model has the advatage of high heating efficiency and uniform heating, which can be widely applied to heating treatment or disinfection of water, beverage, liquid chemical material, petroleum and others.

Two, background technology

The Electric radiant Heating Film heating technique that new development is got up is to mix with film forming matter with semi-conducting material or conductive particle to be coated on the container type device that insulating materials makes, be used to produce fuel factor, come medium is heated, realize the heat conversion of electricity, it is low to have the heating basal temperature, heat-transfer area is bigger, safety, long advantage of life-span.Existing medium type heating appliances usually all is coated on Electric radiant Heating Film the bottom or the sidepiece of container, exist generate heat and can not make full use of, Electric radiant Heating Film drawback such as need protection.So Electric radiant Heating Film generally is used for kettle, boils the milk kettle, Electric radiant Heating Film direct-heating-type radiator etc.

Three, summary of the invention

The utility model utilizes the superiority of Electric radiant Heating Film heating technique, structurally, overcomes Electric radiant Heating Film and is provided with improper and influences the problem of heat utilization and Electric radiant Heating Film protection problem.Design a kind of Electric radiant Heating Film liquid heater that is mainly used in the liquid medium heating.

Technical scheme is to make the heater jacket pipe with one section pipe.Make the heater inner sleeve with the high pipe of thermal conductivity again, inner sleeve relative aperture outer tube is little, and concentric parallel placing in it.Establish the insulating heat-conductive layer at the inner sleeve inwall, application Electric radiant Heating Film on the insulating heat-conductive layer, Electric radiant Heating Film is connected with power supply by binding post, as heater element.Be provided with heat exchange fin at the inner sleeve outer wall, and form flow channel for liquids.Install shrouding additional at inside and outside sleeve pipe two ends, the formed cavity of inside and outside sleeve pipe is sealed by the bolt or the mode of welding.On shrouding, be respectively equipped with feed tube and drain pipe.

Four, description of drawings

Fig. 1 is the utility model structure chart

Fig. 2 is the utility model disk shape heat exchange fin mounting means figure

Among Fig. 1,1 is the heater jacket pipe, and heater inner sleeve 3 is installed within it with one heart, is fixedly connected with shrouding 2 at inside and outside sleeve pipe two ends by shrouding connecting bolt 2a and shrouding coupling nut 2b, is used to seal formed cavity volume between the inside and outside sleeve pipe.At one end shrouding is provided with feed tube 5, is provided with drain pipe 6 on other end shrouding.Be provided with insulating heat-conductive layer 4 in heater inner sleeve 3 inboards, on the insulating heat-conductive layer, be provided with electric membranous layer 4a, be respectively equipped with binding post 4b in the electric membranous layer both sides.In the heater inner sleeve outside heater heat exchange fin 3a is housed.Twist, the fin outer rim contacts with outer sleeve inner wall, forms spiral flow channel between fin.

Among Fig. 2,3 is inner sleeve, is provided with insulating heat-conductive layer 4 and electric membranous layer 4a within it, is set with disk shape heat exchange fin 3a in the outer rim of inner sleeve, which is provided with several thin discharge orifice 3a1.

Five, the specific embodiment

Make the Electric radiant Heating Film liquid heater with the utility model scheme

A, structure constitute

Make outer tube 1 with the metal tube cut-out, and cut off and the isometric inner sleeve 3 of making of outer tube with high copper of thermal conductivity or aluminum pipe, make heater spiral heat exchange fin or disk shape heat exchange fin 3a with copper coin, aluminium sheet or corrosion resistant plate, and be welded on the outer wall of inner sleeve 3.Inwall at inner sleeve coats one deck insulating heat-conductive layer 4, coats one deck electric membranous layer 4a thereon again, then, be heating and curing or sintering, make insulating heat-conductive layer and inner sleeve wall and electric membranous layer strong bonded, establish binding post 4b, in order to be connected with power line at the electric membranous layer two ends.The inner sleeve that makes is placed in the outer tube inner chamber, and two ends are connected and fixed by shrouding connecting bolt 2a and shrouding coupling nut 2b with shrouding 2, when sealing, sealing gasket or other encapsulant can be installed between sleeve pipe and shrouding, guarantee the inner chamber body sealing.The installation of shrouding also can be adopted the mode and the internal and external casing sealing of welding.Feed tube 5 is installed on heater one side seal board, and opposite side is installed drain pipe 6, and both are parallel and on 180 ° of planes, inside is connected with helical form heat exchange fin or the formed helical form tube chamber of disk shape heat exchange fin, and form runner.

The helical form heat exchange wing need weld or be socketed on the inner sleeve outer rim, forms the spiral water flow road between helical wing plate.And disk shape heat exchange fin is to weld with one heart or be socketed on the inner sleeve outer rim, can be spaced installation by several, during installation, with two thin discharge orifice relative tilt certain angle, be clockwise or counterclockwise and arrange, then each corresponding discharge orifice of dredging has just been formed the helical form runner.

B, install and use

When adopting the utility model as liquid heater, can it be connected in container downside or the pipe-line system by pipeline, make it to constitute the heat cycles loop.Be heated liquid and flow to the fluid pipe end, and make the liquid temperature be subjected to inner sleeve and heat exchange fin effect and heat up, reach the purpose of heating from the feed liquor pipe end.

The utility model heater can be horizontal or be perpendicularly put installation, does not influence flowing of the thermal efficiency and heating fluid.

C, superiority analysis

The utlity model has two big advantages, the one, adopt the built-in mode of heating of Electric radiant Heating Film, guarantee that promptly Electric radiant Heating Film is not damaged, the heat safety that it distributed is absorbed and used, its heat loss rate is low, and heat utilization efficiency can reach more than 90%.It is efficient energy-saving.The 2nd, heat exchange fin is installed on inner sleeve, not only under the smaller volume space, be provided with more heat exchange area, and, also form helical flow path, help to be heated the progressively heating of liquid.The effect that makes liquid obtain stirring in heating makes homogeneous heating.

D, application

Isolate the Electric radiant Heating Film heating owing to the utlity model has, efficient height not only, and not have the danger of leaking electricity, and the flames of anger, homogeneous heating, the heat effect time is long.Thereby, can extensively use in fields such as food, chemical industry, oil, household electrical appliance as liquid heater spare.

For example: the hot sterilizer of making beverage milk, vinegar, soy sauce etc.; Make electric heater or solar water heater supplemental heater; Occupy residence heating device or air-conditioner heater; Make the heater of chemical liquid stream; That makes petroleum pipeline adds expansion loop etc.
