The technical scheme of the utility model comprises a water tank inner body, an outer shell, and a water inlet tube and a water outlet tube which both are arranged at the inner body, the inner body is not provided with insert holes for vacuum heat collection tubes, the vacuum heat collection tubes are matched with the co-jointed tank having insert holes, two ends of the co-jointed tank are respectively communicated with the low end and the high end of a heat conduction inclined tube in the inner body through ducts to form a closed independent heating medium circulation structure. The joint of both the high end of the heat conduction inclined tube and the duct are guided upwardly to be connected with the air exhaust tube arranged above the inner body, the air exhaust tube is communicated with the air exhaust opening above the inner body through duct. The utility model has the beneficial effects that the heat energy is transferred by the heat conduction inclined tube through the inner body of the solar energy hot water heater, the built-in heat conduction structure can improve heat efficiency and has constant water temperature, and can enhance water temperature of hot water heater, reduce the cost and prolong the service life (about 10-15 years).

Description

The conduct heat conjuncted water tank of non-bearing type water heater of outside header of inner inclined tube

(1) technical field

The utility model relates to the apparatus for heating water by solar energy field, specifically is the outside conjuncted cisten mechanism of a kind of non-bearing type solar water heater.

(2) background technology

At present, the interior most of water heater of field of solar energy is perforate installation vacuum tube on inner bag directly, forms a closed-loop path between inner bag and the vacuum tube, and water circulates in this loop.The principle of this solar water heater is after vacuum tube absorbs the heat of the sun, and the coolant-temperature gage in the vacuum tube is raise, and rises in the inner bag of eminence.The low water of temperature in the inner bag then can flow in the vacuum tube and heat.By so continuous circulation the water temperature in the inner bag is raise gradually.The water heater of this frame mode is owing to directly open a lot of vacuum pores on inner bag, in case seal badly, O-ring seal wears out, and serious drainage will occur.And water directly heating in vacuum tube, phenomenons such as bombing, fouling, bursting by freezing can appear in vacuum tube.A little less than sunray, situations such as cloudy day, the water temperature decrease speed is fast.What a kind of in the market new construction adopted is the heating of internal helicoid copper pipe, and copper pipe passes the inner bag that is filled with thermal medium, and its principle is that cold water is by copper pipe one side inflow, through spiral copper pipe absorbs heat in thermal medium after, by opposite side discharge hot water.The water heater antileaking of this frame mode, but the hot water amount is little, flow is in a single day too fast, and water temperature just can descend, and adopts its cost of copper pipe also than higher.

(3) summary of the invention

Many in order to improve the existing solar water heater hidden danger of leaking, the thermal efficiency is low, various shortcoming such as water temperature instability, the conjuncted water tank of non-bearing type water heater that the utility model provides a kind of inner inclined tube to conduct heat outside header.The water heater of this structure adds hot water by heat-transfer tube, and the water heater hidden danger of leaking is significantly reduced, and the thermal efficiency improves, and is convenient to maintenance, and increase service life.

This utility model water heater as heat-transfer tube, behind the inclination certain angle is installed in a stainless steel inclined tube in the enamel inner container, links together with the header that vacuum tube is housed outside the tank, constitutes the pipeline of a closure.In this pipeline, added heat transfer medium solution.Heat transfer medium solution absorbs heat in vacuum tube after, be recycled in the heat transfer inclined tube, the heat transfer inclined tube of high-temperature just can directly heat the water in the inner bag.

The technical scheme that the utility model adopted comprises: inner water tank, shell, and be arranged on water inlet pipe and water outlet pipe on the inner bag, the vacuum heat collection pipe jack is not set on the inner bag, vacuum heat collection pipe cooperates with the jack header that has, the two ends of header are communicated with heat transfer inclined tube low side position and high-end position in being arranged on inner bag by conduit respectively, and independently heat medium loop structure is sealed in formation.

Upwards draw with the junction of conduit in the high-end position of heat transfer inclined tube and to receive the blast pipe that is positioned at inner bag top, blast pipe is communicated with by the exhaust outlet of conduit with inner bag top simultaneously.

On blast pipe, also be provided with overflow pipe.

In inner bag, also be provided with electric heating assembly and be arranged on electrical heating hood-protecting assembly on the shell.

Be provided with insulation material between inner bag and the shell, in all component all is wrapped in by shell except that header.

The beneficial effects of the utility model are: conduct heat energy by a heat transfer inclined tube that passes in the solar water heater liner, this built-in heat transfer structure improves the thermal efficiency, and water temperature is constant, promoted the water temperature of water heater greatly, and cost reduces, and prolong service life, approximately 10-15.

Accompanying drawing is a kind of example structure schematic diagram of the present utility model.

The each several part title is in the accompanying drawing: 1. shell 2. enamel inner containers 3. level sensors are placed mouthful 4. heat transfer inclined tubes, the 5. blast pipes filler 6. overfalls 7. electrical heating hood-protecting assemblies 8. electric heating assemblies 9. headers 10. inlet/outlet pipes 11. support connecting bolt assemblies of double as heat medium simultaneously.

(5) specific embodiment

The specific embodiment of the present utility model is: heat transfer inclined tube 4 passes enamel inner container 2 and is connected on the header 9, on the header 9 vacuum tube is installed.Formed the pipeline of a closure like this between heat transfer inclined tube 4, header 9, the vacuum tube.In this pipeline, add and have heat accumulation function, the heat transfer medium solution that heat conduction efficiency is high.Medium solution absorbs heat in vacuum tube after, be recycled in the heat transfer inclined tube 4, carry out heat exchange with water in the inner bag 2, the medium solution of cooling is got back in the vacuum tube again and is heated, and carries out next one circulation.When a little less than the sunshine,, keep the temperature of water because the accumulation of energy effect of medium still can be brought into play heat.

Water inlet pipe and water outlet pipe 10 is connected between inner bag 2 bottoms and the running water pipe.Blast pipe 5 protrudes upward shell 1, on top, overflow pipe 6 and the header 9 that is connected to downwards inner bag 2 successively and the three-way pipe of heat transfer inclined tube 4, play the effect of the filler of getting rid of steam and double as heat medium, exhaust outlet by inner bag top can also be to the automatic supplementing water of heat medium simultaneously, so just needn't artificial supplementation medium moisture.

It is in order to replenish the heat energy use under the situation of water temperature deficiency for a long time in the winter time that inner bag 2 bottoms connect electric heating assembly 8.Inner bag 2 is provided with level sensor and places mouth 3, so that level sensor is installed.

Be provided with insulation material between inner bag 2 and the shell 1, all component except that electrical heating hood-protecting assembly 6 and header 9 is convenient to installation and maintenance in all being wrapped in by shell like this.
