Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to figs. 1 to Fig. 3, a kind of cast aluminium electric heater, includes heater body and the columnar urceolus 4 of heat-generating pipe 1, heat exchanger tube 2 and cast aluminium layer 3 formation.
Described heat-generating pipe 1 includes 4 U-shaped heat-generating pipes, with 2 pieces of connecting plates 10, the two end electrodes of 4 U-shaped heat-generating pipes is connected in parallel into positive terminal and anode connector.The two ends of described heat exchanger tube 2 are respectively heat exchange inlet segment 21 and heat exchange water exit end 22, all the other are interlude, and the interlude of heat exchanger tube 2 coils the outside in heat-generating pipe 1; The interlude of the interlude of heat exchanger tube 2 and heat-generating pipe 1 is surrounded filling formation cylinder-shaped body heat exchanging segment by cast aluminium layer 3, and main body heat exchanging segment has interior intake tunnel 20, and interior intake tunnel 20 is through cast aluminium layer 3 and heat exchanger tube 2, and its external port is positioned at the side of cast aluminium layer 3.
One end of described urceolus 4 has opening, the opening of urceolus 4 also has flanging 41, main body heat exchanging segment is close to cover cap by urceolus 4, urceolus 4 has perforate in the external port place of interior intake tunnel 20, the heat exchange water exit end 22 of heat exchanger tube 2 passes urceolus 4, and the heat exchange inlet segment 21 of heat exchanger tube 2 and the positive terminal of heat-generating pipe 1 and anode connector pass the opening of urceolus 4.
With reference to figure 4, a kind of multimode single-core preheating and instant electric hydrophone, it includes inner bag 5 and above-mentioned cast aluminium electric heater, one end of inner bag 5 has installing port, cast aluminium electric heater is tightly connected by the installing port of mount pad 6 with inner bag 5, the heat exchange inlet segment 21 of cast aluminium electric heater is as water inlet pipe, and an outlet pipe 52 is through inner bag 5; Be provided with into water mozzle 7 and water outlet mozzle 8 in inner bag 5, the head end of water inlet mozzle 7 connects the heat exchange water exit end 22 of logical cast aluminium electric heater, the end of water inlet mozzle 7 is away from cast aluminium electric heater, one end of water outlet mozzle 8 connects pass-out water pipe 52, the end of the other end close water inlet mozzle 7 of water outlet mozzle 8, a kuppe 9 is by the end of water inlet mozzle 7 and water outlet mozzle 8 end shield lid.
When the electric heater of the present embodiment is installed, by the outer end of outlet pipe 52 serial connection outlet valve etc. to export use, the outer end (heat exchange inlet segment 21 end of heat exchanger tube 2) of water inlet pipe is connected logical running water pipe, and running water is made to fill the cold water transported by running water pipe in inner bag 5 by heat exchanger tube 2 → water inlet mozzle 7 of water inlet pipe 21 → cast aluminium electric heater.
The electric heater of the present embodiment is set with preheating, instant heating and pre-instant heating relay three kinds of mode of operations.
Preheating mode; use during cold weather; specifically: in inner bag 5, fill water; outlet valve is closed, the anhydrous outflow of outlet pipe 52, and preheating heating starts, heater work; heater is by the water heating in the water of heat exchanger body surfaces and heat exchanger tube 2; form the circulation of Base Heat liter waterborne, the decline of top cold water in inner bag, until the water in inner bag 5 to be heated to pre-heat setting temperature (80 DEG C), electric heater is shut down.Urceolus 4 serves the cast aluminium layer 3 of isolation heater and the effect of water body, avoids water body that cast aluminium layer 3 is hydrolyzed, and ensures the service life of electric heater.
Pre-instant heating relay pattern, after preheating mode terminates, user can open outlet valve water, outlet pipe 52 exports the water through preheating, the cold water simultaneously being continued to enter by water inlet pipe 21 supplements, (with hot water rapid mixing in kuppe 9) → water outlet mozzle 8 → outlet pipe 52 in portion of cold water → heat exchanger tube 2 → water inlet mozzle 7 → kuppe 9, portion of cold water enters in inner bag 5 from intake tunnel 20 in cast aluminium electric heater simultaneously, in the top that the hot water promoting preheating mode heating continues to rise to inner bag 5 and kuppe 9, when leaving water temperature is reduced to below user's design temperature, pre-instant heating relay pattern starts, heater is started working, water in inner bag 5 and the water flowing through heat exchanger tube 2 are heated simultaneously, ensure that leaving water temperature is for the comfortable use of user.
I.e. heat pattern, use when weather is not cold, specifically: outlet valve is opened, cold water is continued to enter heat exchanger tube 2 by water inlet pipe 21, instant heating heating starts, the cold water flowing through heat exchanger tube 2 heats rapidly by heater, hot water by the mozzle 7 → kuppe 9 of intaking → water outlet mozzle 8 → outlet pipe 52 → outlet valve exports, kuppe 9 serves water outlet mozzle 8 when reducing hot water and the contact surface of cold water, i.e. heat pattern and preferentially exports the effect of hot water, being conducive to instant heating heating effect, being convenient to the use hot water of user without the need to waiting for.
