Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain and from the limitation of embodiment.

Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members Part or other parts.

Fig. 1 shows a kind of solar water heater based on hot and cold water convection current according to the utility model preferred embodiment Structure diagram, should solar water heater based on hot and cold water convection current include vacuum heat absorbing pipe 1 and water tank 2, several are true Suction heat pipe 1 and water tank 2 are arranged on stent.Water tank 2 includes babinet, the first isolation board 3, the second isolation board 6, the first check valve 10th, the second check valve 11 and the 3rd check valve 12.With reference to figure 1, the first isolation board 3 is made by heat-barrier material, first every It is vertically installed in from plate 3 in babinet 1, and the first isolation board 3 separates the inner cavity of babinet 1 two chambers in about distribution, it is left Water in right two chambers cannot be exchanged heat by the first isolation board 3.Chamber wherein positioned at the left side is hot hydroecium 4, and hot hydroecium 4 sets Water outlet 5 is equipped with, water outlet 5 is located at the left end of the bottom of hot hydroecium 4.

With continued reference to Fig. 1, the second isolation board 6 is made by heat-barrier material, and the second isolation board 6 is arranged at positioned at the right In chamber, and the chamber positioned at the right is separated into warm water chamber 7 above and underlying cold water by the second isolation board 6 Room 8, the right end of cold water chamber 8 are provided with a water inlet 9.Water in cold water chamber 8 and warm water chamber 7 cannot by the second isolation board 6 into Row heat exchange.Hot hydroecium 4 is not connected with vacuum heat absorbing pipe 1, and all vacuum heat absorbing pipes 1 are connected with cold water chamber 8, or hot hydroecium 4 It is connected with partial vacuum endothermic tube 1, remaining vacuum heat absorbing pipe 1 is all connected with cold water chamber 8.Second isolation board 6 is from left to right Tilt down, so that the bottom of warm water chamber 7 tilts down from left to right, and the top of cold water chamber 8 is inclined upwardly from right-to-left.

With continued reference to Fig. 1, the first check valve 10 is arranged at the left end of the second isolation board 6, its close to the first isolation board 3 and Between warm water chamber 7 and cold water chamber 8, the water of 8 left end of cold water chamber can be flowed into warm water chamber 7 by the first check valve 10.The Two check valves 11 are arranged at the right end of the second isolation board 6, it is between warm water chamber 7 and cold water chamber 8, the water of 7 right end of warm water chamber Cold water chamber 8 can be back to by the second check valve 11.3rd check valve 12 is arranged at the upper end of the first isolation board 3, it is located at Between warm water chamber 7 and hot hydroecium 4, the water of 7 left end of warm water chamber can be flowed into hot hydroecium 4 by the 3rd check valve 12.

Water tank 2 is separated into hot hydroecium 4, cold water chamber 8 and warm water chamber 7 by the utility model, and during use, utilization is cold The principle of hot water free convection, the cold water entered from water inlet 9 in cold water chamber 8 sink to the vacuum being connected with cold water chamber 8 and inhale Heated in heat pipe 1, since the top of cold water chamber 8 is right low left high, and cold water is entered from right end, therefore vacuum heat absorbing pipe 1 heats Obtained hot water can exchange the left end at the top for rising to cold water chamber 8, and a left side for warm water chamber 7 is flowed into by the first check valve 10 End；When hot water enters the left end of warm water chamber 7, due to the bottom right low left high of warm water chamber 7, the temperature in warm water chamber 7 originally Relatively low water will sink to right end bottom along the second isolation board 6 and be back to cold water chamber 8 through the second check valve 11, then by true Suction heat pipe 1 reheats, and the water of the left end of warm water chamber 7 can remain the hot water for just going up to come after cold water chamber 8 heats；Into Hot hydroecium 4 can be entered through the 3rd check valve 12 by entering hot water in 7 left end of warm water chamber, and the hot water in hot hydroecium 4 is again through water outlet 5 Outflow supply user uses.The utility model can improve the efficiency of the cold and hot water coke slurry of solar water heater, and only need to concentrate Hot hydroecium 4 can be transported to after being heated to the water of part, then user is supplied by water outlet 5 and is used, without to whole Water in a water tank 2 could supply user's use after being heated, so as to improve the efficiency of solar water heater heating, with Rapidly hot water is supplied for user.Preferably, the width of hot hydroecium 4 in left-right direction is less than the width of cold water chamber 8 in left-right direction Degree, so that cold water chamber 8 has more spaces to be connected with more vacuum heat absorbing pipes 1, to further improve the efficiency of heating surface.

With continued reference to Fig. 1, further, a heating unit 13 is provided with hot hydroecium 4, it is electric heater unit.It is if hot Hot water temperature in hydroecium 4 does not reach requirement, then the water in hot hydroecium 4 can sink to the vacuum heat absorbing pipe 1 being connected with hot hydroecium 4 In continue to heat, can also open heating unit 13 and the water in hot hydroecium 4 is heated, or by heating unit 13 to hot water Water in room 4 is kept the temperature, to ensure to meet use demand of the user to hot water.

The description of the foregoing specific exemplary embodiment to the utility model be in order to illustrate and illustration purpose.These Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explain the certain principles of the utility model And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the utility model Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shape Formula is limited.
