Specific embodiment
To make technical scheme and advantage clearer, with reference to the accompanying drawing in the embodiment of the present invention, to this
Technical scheme in inventive embodiments carries out clearly complete description：
The non-immersion electric water heater of a kind of interior-heat as shown in Figure 1-Figure 3, by heated body is heated with heat exchanger tube 2
Water and calandria are that heating element heater 6 is isolated, and the outer surface of heat exchanger tube 2 is immersed in heated water, are cavitys inside heat exchanger tube 2.
Heating element heater 6 is placed in cavity.That is calandria is among the encirclement of heated body, but calandria is immersed among heated body,
Concrete scheme is：
Including barrel cover 1, the inside of barrel cover 1 is provided with multiple heat exchanger tubes 2, heat exchanger tube 2 along ladle body direction and sets
It is equipped with insulation tube 7, insulation tube 7 and is provided with heating element heater 6, the water inlet 3 and water outlet for interpenetrating is provided with barrel cover 1
Mouth 4, the end of outlet 4 is connected with aqua storage tank 8, and aqua storage tank 8 is connected with water pump 9, and water pump 9 is connected with water inlet 3.
Further, the upper surface and lower surface of barrel cover 1 is provided with end plate 5, and heat exchanger tube 2 is through end plate 5 along tubbiness
The ladle body direction of housing 1 is arranged, two end plates 5, the tube wall outside of heat exchanger tube 2 and being heated for one sealing of the formation of barrel cover 1
Cavity.And the inwall of heat exchanger tube 2 and its internal insulation tube 7 and heating element heater 6 form calandria.
Further, the end plate 5 is arranged with the end welding of multiple heat exchanger tubes 2.This ensure that calandria and be heated
Body is adequately isolated setting.
Under working condition：Heating element heater 6 is switched on power, the heat that heating element heater 6 is produced will be exchanged heat by insulation tube 7
Pipe 2 is heated, and starts water pump 9, and the water in aqua storage tank 8 enters water pump 9 by pipeline 10, through pipeline 10 after water pump 9 pressurizes
With water inlet 3 i.e. enter closed shell, water heat exchanger tube 2 outer surface flow at high speed, while receive heat exchanger tube 2 be conducted through come
Heat, flows out after being heated from outlet 4, and by pipeline 10 aqua storage tank 8 is returned, and moves in circles, and reaches to the coolant-temperature gage of aqua storage tank 8
Require, turn off heating power supply and water pump 9.
The present invention provides a kind of calandria and heated body is separated, while calandria and heated body heat-conducting area are maximum, heat conduction
A kind of most short non-invasive electric water heater of distance.Will the heater of water and the storage device of water separate.Logical
In the state of electrical heating, the water in the storage device of water is exported, in the presence of water pump 9 in heater default runner
In force quick flowing, the heat that heating 6 is produced to be conducted to from tube wall inner side by heat exchange tube wall quick on the outside of tube wall
The water of flowing heats in water, and heated water returns again to the storage device of water, and mixes with the water in the storage device of water.So
Move in circles, until the coolant-temperature gage in the storage device of water reaches and needs temperature.The device considers the electricity of " water bag fire " mode
Heat pipes heat, heating tube needs to be immersed in water during work, because insulating properties is difficult to solve, it is impossible to which high voltage is directly used.This
Device is isolated in water and heating element heater 6 using heat exchanger tube 5, and leave between heating element heater 6 and the inwall of heat exchanger tube 5 can be with
Freely regulated clearance space, for improving the insulating properties of heating element heater 6, to be suitable for the requirement that high voltage is directly used.Together
When the device consider that the clearance distance of heating element heater 6 and the inwall of heat exchanger tube 5 is directly affected between heating element heater 6 and heat exchanger tube 5
Heat-transfer rate, so ensureing to reduce clearance distance as far as possible on the premise of insulating properties is required.And effectively utilizes spoke during considering
Penetrate, various heat-conducting modes such as convection current and conduction of heat.So the technical program not only solves electric-heating water because heating element heater is exhausted
Edge can not directly use a high-tension difficult problem, while it is slow also to solve the problems, such as that " fiery Bao Shui " mode heats heat-transfer rate.
As shown in Figure 4 and Figure 5, can be used for producing steam using this programme.Will the storage device of water be arranged to close
Container is closed, hermetic container top arranges steam outlet, while arranging water supplement port B, discharge outlet C etc. on hermetic container.Or will
Barrel cover removes the water inlet and outlet on barrel cover as hermetic container, steam is arranged at the top of barrel cover defeated
Outlet, and water supplement port B, discharge outlet are set on barrel cover.In position valves such as steam outlet C, water supplement port B, discharge outlet C
Close, when hermetic container is in air-tight state, when the water inside hermetic container is heated above 100 DEG C, steam outlet can
To produce steam.Change the temperature of the water in hermetic container, it is possible to produce the steam of different pressures.
Direct mode produces the device of steam.A kind of new electric water heater as shown in Figure 4.Device
Two parts are constituted, i.e. heated body, hot body.The barrel cover 1 that heated body is rolled including steel plate, seamless steel pipe conduct
Heat exchanger tube, end plate 5 is processed with steel plate.Heating element heater 6 adopts heating wire, insulation tube 7 to adopt earthenware in calandria.In housing simultaneously
Row are provided with multigroup heat exchanger tube.Steam (vapor) outlet A, water supplement port B, discharge outlet C are set on housing.Processing method is, 1 liang of barrel cover
End and two end plates 5 are welded, and the mouth of pipe of heat exchanger tube 2 are placed in the perforate of two end plates 5 outside.And outer surface and the end of heat exchanger tube 5
Plate weld.So, barrel cover 1, two end plates 5 and the outer surface of heat exchanger tube 2 surround the housing of a closing.On the top of housing
Welding steam (vapor) outlet A, side welding water supplement port B, discharge outlet C.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
