Description
One, technical field
The utility model provides the heating equipment in thermal technology field, specifically the closed circuit electric heating equipment of negative pressure.
Two, background technology
In the thermal cycle heating that utilizes heat-conducting work medium is the heating facility of device widespread usage.Usually be divided into hot-water heating and hot air heating, heater block is generally fuel boiler.This heating plant, it is even to have heating, layout easily, the advantage that cost is low, thereby, extensively be used.And be that the heating plant of the energy has the infrared ray electric warmer, the variety type of units such as electric heating installation using oil as medium with the electricity.Advantage is a conveniently moving, heat up rapidly, but thermal balance is poor, and local temperature height, and with xeothermic sense, thereby, heating system and adopting as a supplement usually.Along with the restriction of coal and oil and environmental protection requirement improve, encourage to utilize the waterpower or the utilization of the nuclear power energy, be development trend for the electric heating of oneself building of on a small scale heating design or resident or dwelling house.
But the open circuit circulation heating system that with water is cycle fluid is more, and establishes vent valve and expansion tank, because circulation is slow, thermal inertia is big, spilling water easily, and gas is stifled and ice is stifled.Thereby, inapplicable in the heating plant that with the electricity is heating source.
Three, summary of the invention
The purpose of this utility model is that a kind of closed circuit negative pressure electric heating equipment is provided.
Technical scheme is, utilizes electrothermal film heater as thermal source, and radiator is a heat exchange device, constitutes the heat-conducting work medium closed circuit by pipeline between Electric radiant Heating Film liquid heater and radiator, and a certain amount of heat-conducting work medium of filling betwixt.Between the heating tube of circulation line and return duct, liquid level gauge is installed, at heating tube one end setting pressure table and negative pressure valve.
Four, description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model negative pressure valve structure chart
Among Fig. 1,1 is the Electric radiant Heating Film liquid heater, at an end downside of Electric radiant Heating Film liquid heater 1 feed tube 1a is installed, and other end top is equipped with drain pipe 1b.Drain pipe is connected with heating tube 4, and pressure gauge 3 and negative pressure valve 2 are installed on heating tube 4.Heating tube is connected to several radiator upper ends with 1, is connected with liquid back pipe 6 by pipeline respectively at the radiator downside.Between liquid back pipe 6 and heating tube 4, be communicated with liquid level gauge 7 is installed.In heater and radiator and pipeline, fill a certain amount of heat-conducting medium 8.
Among Fig. 2, be provided with valve seat 4a at heating tube 4 one ends, heating tube and negative pressure valve body 2a join, on the valve seat 4a within it spool 2b is installed, the spool rear end is equipped with spring 2c, is provided with the liquid injecting mouth 2d that bleeds at the tail end of valve body, and pressure regulation post 2e is installed in the hole within it, be provided with defeated discharge orifice 2f on the pressure regulation post, spring 2c places between spool 2b and the pressure regulation post 2e.
Five, the specific embodiment
Utilize the utility model scheme system household heating device
A, according to heating area, selecting has the Electric radiant Heating Film liquid heater of full-amount heat capacity power as heater element.
B, be provided with and needs attractive in appearance are selected plate-fin type, suitablely usually select the little area of dissipation of volume big, compact conformation, the tubular type sheet string type fin of good looking appearance according to the space.
C, select good steel pipe of air-tightness or plastic-aluminum pipe as connecting pipe.
D, the withstand voltage glass tube of selection are as liquid level gauge.
E, the positive and negative duty pressure table of selection are as Pressure gauge.
F, selection check valve are as negative pressure valve.
G, fin can be one or more groups, can install in a Room or the multicell, connect by the pipeline assembling.
Deploy by structure shown in Figure 1, each parts combination is installed.Guarantee being horizontally disposed with of heating tube and liquid back pipe.
Heating plant install combination complete after, insert vavuum pump by negative pressure valve, the air in the withdrawing device adds the heat-conducting work medium of total measurement (volume) about 1/3 simultaneously, closes negative pressure valve.
H, use and the course of work
Behind the power supply of connecting the Electric radiant Heating Film liquid heater, built-in Electric radiant Heating Film heat generating member unit promptly generates heat, and passes through heat exchange action, the heat-conducting work medium that places in it is heated up, because apparatus system is a negative pressure, Gu and, the heat-conducting work medium boiling point is lower, and is easy to vaporization, rises rapidly, and in the arrival fin, be subjected to the conduction of heat of fin, make the heat-conducting work medium cooling liquefaction of vaporization, proportion strengthens, form drop, be dropped in the bottom of radiator, in the liquid back pipe that confluxes.Because the heater continuous operation constantly make the working medium vaporization, and liquid back pipe replenishes constantly, and heat-conducting work medium is constantly circulated between heater and radiator, thereby realizes the purpose of interior space heating.
Because the utility model heating plant adopts the Electric radiant Heating Film liquid heater as heating source, has safety, the advantage that heat utilization efficiency is high.Owing to adopt closed circuit negative pressure heat-conducting work medium circulation, has quick heating again, the heat conduction advantage of uniform again.Also, help observing the number change of cycle fluid, help maintenance and guarantee safe condition operation down owing on device, Pressure gauge is housed and liquid level is taken into account negative pressure valve.The suitable freezing point that adopts of heat-conducting work medium is low, and the big liquid of heat of evaporation, guarantees stable circulation, and prevents to freeze the generation of stifled phenomenon.
The utility model heating plant is suitable to divide the family central heating, and higher, inflammable, the explosive occasion of specification requirement adopts.
