Abstract

A solar water heater comprises a frame and a vacuum tube. The vacuum tube is transparent in the whole body, an inner metal tube is arranged in the vacuum tube, the outer surface of the inner metal tube is coated with a heat absorbing coating layer, an outer casing which is an upper-opened rectangular box is arranged outside the vacuum tube, a heat-insulating material arranged inside the outer casing is provided with a recess in the shape matching with that of the vacuum tube, the outer casing is supported by the frame, the lower end of the inner metal tube is sealed by an inner tube seal plate, an exhaust overflow branch and a water inlet and outlet pipe are connected with an external pipeline after penetrating through the inner tube seal plate, and the exhaust overflow branch is connected with an exhaust overflow main pipe after penetrating out of the outer casing. As a heat collecting tube is inverted, directly heated water in the heat collecting tube can be utilized sufficiently, and then a water tank is substituted. Simultaneously, the problem that vacuum tubes are blast because water in the vacuum tubes is heated directly is resolved by aid of the inner metal tube arranged in the vacuum tube. Above all, as the solar water heater can realize hot water collection without the water tank, heat collection effect is increased.

Description

Solar water heater

Technical field

The utility model relates to a kind of civil solar use device, relates in particular to a kind of solar water heater.

Background technology

Solar water heater is as an energy-conserving and environment-protective equipment, solar facilities kind brand in the market is various, 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.The water tank of existing water heater is the hot water storage device, because it is unsatisfactory to be in outdoor itself heat-insulating property, especially at night, heat loss is bigger.In addition, existing thermal-collecting tube of solar water heater is thinner, and water capacity is less.

Summary of the invention

The utility model purpose provides a kind of solar water heater that hot water in the thermal-collecting tube all can be utilized.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of 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, the outer surface of metal inner pipe scribbles heat absorbing coating, it is characterized in that: vacuum tube is outside to be shell, and shell is designed to the open rectangle box body in top, insulation material design in it has the depression consistent with the vacuum tube shape, and vacuum tube and its inner metal inner pipe place in this depression; Shell is supported by support body; The metal inner pipe lower end is sealed by interior pipe shrouding, and the exhaustion spill arm passes interior pipe shrouding with water inlet pipe and water outlet pipe and links to each other with exterior tubing, and the exhaustion spill arm passes outside the shell and links to each other with the exhaustion spill house steward.

Above-mentioned a kind of solar water heater is characterized in that: in metal inner pipe, exhaustion spill arm aperture position is higher, and the aperture position of water inlet pipe and water outlet pipe is lower; The spacing cushion rubber of design between pipe and the metal inner pipe top in vacuum tube; The insulation material longitudinal profile is " J " shape, the interior pipe shrouding of bottom can be wrapped up fully like this.Two in vacuum tube is one group, and their water inlet pipe and water outlet pipe position is connected with the Inlet and outlet water house steward in opposite directions and by threeway.

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 water tank and collects hot water, has improved collecting efficiency.

The utility model is further described below in conjunction with drawings and Examples.

The specific embodiment

Embodiment 1

As shown in Figure 1 and Figure 2, a kind of solar water heater, it comprises support body and vacuum tube 2, all transparent inside and outside the vacuum tube 2, it is built-in with metal inner pipe 3, the spacing cushion rubber of design between pipe and metal inner pipe 3 tops in vacuum tube 2; The outer surface of metal inner pipe 3 scribbles heat absorbing coating, the vacuum tube outside is a shell 9, shell 9 is designed to the open rectangle box body in top, and insulation material 6 designs in it have the depression consistent with the vacuum tube shape, and vacuum tube 2 and its inner metal inner pipe 3 place in this depression; Insulation material 6 longitudinal profiles are " J " shape, and shell 9 is supported by support body; The metal inner pipe lower end is by interior pipe shrouding 5 sealings, and exhaustion spill arm 4 passes interior pipe shrouding 5 with water inlet pipe and water outlet pipe 7 and links to each other with exterior tubing, and in metal inner pipe 3, exhaustion spill arm 4 aperture positions are higher, and the aperture position of water inlet pipe and water outlet pipe 7 is lower; Exhaustion spill arm 4 passes outside the shell and links to each other with exhaustion spill house steward 1.Two in vacuum tube is one group, and their water inlet pipe and water outlet pipe position also is connected with the Inlet and outlet water house steward by threeway 8 in opposite directions.The vacuum tube water capacity is bigger, therefore can design as required in actual use one group, two or more sets.
