Description
Technical field
The present invention relates to a kind of civil solar use device, relate in particular to the solar water heater that a kind of solar energy heat collection pipe adopts invert form.
Background technology
Solar water heater has good market prospects under country's guiding at present as an energy-conserving and environment-protective equipment.Solar facilities kind brand in the market is various, basic structure does not but have much variations, the most common solar water heater mainly comprises three parts: support body, water tank, solar energy heat collection pipe, solar energy heat collection pipe is a double layer vacuum tube, the one end encapsulation other end is open, the socket joint hole of water tank bottom is inserted in the open end, and blind end tilts to be bearing on the support body.The thermal-collecting tube inner chamber communicates with water tank cavity, and the back convection current enters and realizes heating process in the water tank thereby water is heated in thermal-collecting tube.The glass heat collection tube of the solar water heater of this version can not pressure-bearing, and bombing takes place in cold climate easily, and bombing not only solar water heater can not be used but also the water light leak in the water tank can be caused waste.For anti-kind situation here produces, the water heater of putting metal inner pipe has appearred on the market adding in solar energy heat collection pipe, it is coated in heat absorbing coating on the outer wall of metal inner pipe, water only is present in thermal-collecting tube and the water tank and does not contact with glass heat collection tube, other structure and common water heater are as broad as long, owing to adopted the structure of metal inner pipe to make vacuum tube can bear certain pressure, and problems such as bombing can not take place, but the hot water in the pipe still can't be utilized, hot water in causing managing is wasted, present water heater thermal-collecting tube caliber and pipe number all constantly increase, and the waste that causes like this is more obvious.
Summary of the invention
The object of the invention provides a kind of water-storing solar water heater that can prevent that not only bombing from can also all utilize hot water in the thermal-collecting tube simultaneously.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of water-storing solar water heater, it comprises support body and vacuum tube, all transparent inside and outside the vacuum tube, it is built-in with metal inner pipe, and the outer surface of metal inner pipe scribbles heat absorbing coating, it is characterized in that: vacuum tube and metal inner pipe all are invert form, the downward blind end of openend upwards, be water containing chamber below vacuum tube and metal inner pipe, the water containing chamber wall is wrapped with insulation material, and insulation material is outward a shell; Shell, insulation material and water containing chamber wall top all have circular hole, the metal inner pipe openend is plugged in the circular hole on the water containing chamber wall and by the metal inner pipe sealing ring and seals, the vacuum tube openend is inserted in the circular hole of insulation material, is located by O-ring seal between vacuum tube and the metal inner pipe Plug Division; In the indoor design of metal inner pipe the exhaustion spill arm of axially parallel is arranged, exhaustion spill arm both ends open, the one end is positioned at vacuum pipe inner cavity top, and its other end is communicated with the exhaustion spill house steward; Be connected with water inlet pipe and water outlet pipe in the water containing chamber lower sidewall.
Above-mentioned a kind of water-storing solar water heater is characterized in that: the wall of metal inner pipe be stamped out parallel vertical tongue or groove.The endotherm area that its can increase on the one hand metal inner pipe can also increase the rupture strength of pipe shaft on the other hand.
Above-mentioned a kind of water-storing solar water heater, it is characterized in that: vacuum tube and metal inner pipe tilt to have a certain degree, the value of this angle is set to make when metal inner pipe is completely annotated the line of its center of gravity and lower edge fulcrum to keep that is to say that vertically metal inner pipe can keep balance under this angle, does not produce the moment of side direction; The spacing cushion rubber of design between pipe and the metal inner pipe in vacuum tube; The vacuum tube potted ends be absorbed in the groove of microscler upper holder and support body pipe shaft is spacing; An exhaustion spill house steward part is positioned at water containing chamber, and another part is divided into blast pipe and overflow pipe after passing shell.
Above-mentioned a kind of water-storing solar water heater is sealed by capping below vacuum tube and metal inner pipe; The design of capping both sides has mounting ear, and capping is fixed on the joist of bottom by mounting ear; Water containing chamber is deformed into the prolongation of locating of water inlet pipe and water outlet pipe, is connected with the Inlet and outlet water arm on the water inlet pipe and water outlet pipe prolongation; In the indoor design of metal inner pipe the exhaustion spill arm of axially parallel is arranged, exhaustion spill arm both ends open, its upper end is positioned at vacuum pipe inner cavity top, its underpart is communicated with the exhaustion spill house steward; Inlet and outlet water arm and exhaustion spill arm pass capping respectively and enter in the vacuum tube; Inlet and outlet water arm aperture position is lower, and exhaustion spill arm aperture position is higher.
From above-mentioned scheme as can be seen, owing to adopted the inverted method of thermal-collecting tube, direct-fired water in the thermal-collecting tube can be fully utilized, thereby reduce even replaced water tank, simultaneously owing to adopted metal inner pipe to prevent from directly vacuum tube flowing water to be produced the problem that bursts.Main ground, it no longer relies on the convection current thermal-arrest, has improved collecting efficiency.
Below in conjunction with drawings and Examples the present invention is further described.
