Technical field

The utility model relates to a kind of solar water heater, refers in particular to a kind of solar water heater that can fit on the skin.

Background technology

In the prior art, solar water heater mainly is installed on the roof in the inclination mode, and this is by its structure decision itself, and its defective is owing to its thermal-arrest part and the necessary disjunctor of storage tank, so volume ratio is bigger, installs also relatively more difficult; In addition, bursting by freezing easily in use, knot dirt descend security performance; In addition, existing water heater can't accomplish that all being close to metope vertically installs, and has influence on the use of a large amount of non-attic resident family, makes applying of solar energy be subjected to very big restriction.

The utility model content

The purpose of this utility model is to design a kind of plate wall-hanging solar water heater, and this water heater can be installed on the exterior wall of building, therefore, can provide solar water heater for the resident family that comprises ground floor.

Its main technical schemes is: in the framework of heat-collecting box glass tube is set, in the glass tube of laterally placing or be similar to laterally placement, the conduction heat pipe is arranged, and, the condensation end of conduction heat pipe stretches out glass tube, in the glass tube of laterally placing or be similar to laterally placement, the thermal-arrest plate is being set, this thermal-arrest plate is connected with the conduction heat pipe, at an end of framework inner water tank is set, and the condensation end that conducts heat pipe is positioned at inner water tank.

Arc groove along its length is set on the thermal-arrest plate, and the conduction heat pipe embeds in the arc groove, links together with the thermal-arrest plate.Angle α is arranged between axis on the width of thermal-arrest plate and horizontal plane, between the axis on the length direction of axis that conducts heat pipe and thermal-arrest plate, angle β is arranged, the water-in and water-out joint is set respectively on inner water tank, seal nipple is set at one section the connecting portion that conducts the close condensation end of heat pipe with glass tube.

Be provided for the keeper of fixing glass pipe in the end of framework, light penetrating panel is set on framework, heat-collecting box utilizes water-in and water-out joint and pipeline to be connected with storage tank, cooling water inlet and hot water outlet are set on storage tank, and on 1 pipeline therein check valve is set, circulating pump and fixed in limited time switch frequently.

The utility model has the advantages that: all install in the mode that tilts owing to reach thermal-arrest plate itself between conduction heat pipe and thermal-arrest plate, compare with original mode, the utility model can be worked as whole heat-collecting box and is when laterally vertically being installed on the skin, higher Heat-collecting effect is still arranged, thereby for solar water heater is laid a good foundation with the mounting means that is affixed on the skin, make solar water heater and building realize perfect the combination, solved in the past and solar water heater can only be installed on the problem of building end face in the inclination mode, for more wide prospect has been opened up in the application of solar water heater.

The specific embodiment

As shown in the figure: in the framework 9 of heat-collecting box 12, glass tube 3 is set, conduction heat pipe 11 is arranged in the glass tube 3, and, the condensation end 5 of conduction heat pipe 11 stretches out glass tube 3, in the glass tube 3 of laterally placing or be similar to laterally placement, thermal-arrest plate 2 is being set, this thermal-arrest plate 2 is connected with conduction heat pipe 11, at an end of framework 9 inner water tank 4 is set, and the condensation end 5 that conducts heat pipe 11 is positioned at inner water tank 4.After sunlight sees through glass tube 3, shines on the thermal-arrest plate 2, make thermal-arrest plate 2 produce heat, by conduction heat pipe 11, heat is passed to its condensation end 5 again, by the water in the condensation end 5 heating inner water tanks 4.

Arc groove along its length is set on thermal-arrest plate 2, and conduction heat pipe 11 embeds in the arc groove, links together with thermal-arrest plate 2.This connected mode can increase the contact area of thermal- arrest plate 2 and 11 of heat pipes of conduction, and improving its heat-transfer effect, so the shape of arc groove should be coincide with the profile of conduction heat pipe 11.

Angle α is arranged between axis on the width of thermal-arrest plate 2 and horizontal plane, it is skewed that the thermal-arrest plate is in, and when heat-collecting box 12 was installed on skin, the thermal-arrest plate 2 of this inclination was just in time towards the sun, therefore can receive sunlight to greatest extent, thereby improve its Heat-collecting effect.

Between the axis on the length direction of axis that conducts heat pipe 11 and thermal-arrest plate 2, angle β is arranged, so that make the conduction heat pipe be in the state of inclination equally, and the condensation end 5 of conduction heat pipe 11 should be higher than its other end, according to the heat conduction principle, the fluid of heat always hoists mobile from lower, after the condensation end of conduction heat pipe 11 is higher than its other end, can promote heat exchange, thereby improve the thermal efficiency.

Water-in and water-out joint 6 or 7 are set, to realize the convective exchange of hot and cold water respectively on inner water tank 4.

One section connecting portion with glass tube 3 at conduction heat pipe 11 close its condensation ends 5 is provided with seal nipple 10, scatters and disappears to avoid heat, improves Heat-collecting effect.

For avoiding glass tube to damage, can be provided for the keeper 8 of fixing glass pipe 3 in the end of framework 9 because of loosening.

Light penetrating panel 1 is set on framework 9, and this light penetrating panel 1 has higher light transmission, therefore, both can improve the quantities received of 2 pairs of sunlight of thermal-arrest plate, but cover glass pipe 3 is avoided the erosion of dust storm, dust again, to prolong the service life of heat-collecting box 12.

Heat-collecting box 12 utilizes water-in and water-out joint 6,7 and pipeline to be connected with storage tank 13, and cooling water inlet 18 and hot water outlet 17 are set on storage tank 13, and check valve 16, circulating pump 15 and fixed in limited time switch 14 frequently are set on 1 pipeline therein.As can see from Figure 5, heat-collecting box 12 is installed with the transverse horizontal shape, this is that the utility model is different from one of main points of other solar water heater, in use, can utilize pipeline that heat-collecting box 12 and storage tank 13 are linked together, heat-collecting box 12 constantly is passed to heat storage tank 13, makes the water in the storage tank 13 obtain heating.For ease of control, check valve 16 can be set on pipeline, because storage tank 13 of the present utility model not necessarily is positioned at the top of heat-collecting box 12, therefore, need utilize circulating pump 15 to impel water to carry out convection current, to guarantee the heat exchange of whole water heater, fixed in limited time switch 14 frequently is an outsourcing piece, its role is to control the work period of circulating pump 15.
